View Full Version : So I want to build a frame.

Yeah, I'm poor, have a welder, and want to build a frame.

I have a crappy Hyper BMX in my garage that I can sacrifice parts like drop outs and the bottom bracket area from etc...

I am planning on buying some steel tubing to build a frame from.

Any tips?

It's going to be a mod style bike... I have a stem that a friend gave me, all I will need really is a set of bars for it. Hell, I could just make a set myself...

Metal is EXTREMELY cheap in my city... mainly because we have Stelco and Dofasco here in Hamilton.

Please don't post if you have negative comments, I don't care if it's heavy, I don't care if it's going to be weak. I only want suggestions to help me build something with decent dimensions for a mod bike.

Yeah, I'm pretty bored, and nobody has posted in my thread looking for Hamilton/Burlington riders... I don't want to sink money into a sport I'm not going to enjoy.

you most likely arent going to enjoy the sport if your trialsing around on some poorly welded piece of a bmx. I would maybe by a used bike or if your really sure about the whole frame building just look at more specs like head tube angles and tube lengths. there really isn't much point in doing a hack job of somthing like this. you will probably want to do a lot a research on the frame.

dont
if you are low on money buy a cheap bike. dont build something that isnt going to work. you will actually end up spending more money in the end doing it your way and it may just discourage from the sport

Whoa there, hack job? It will be fine, it's just going to be heavier than an aluminum mod bike. I'm asking for tips, not for people to degrade my metal working skills.

Would you suggest a long frame? Higher top tube like a Monty? Or a low one welded to the down tube like a Zoo!?

I mean poor like, I don't have $100 to buy parts, I was planning on buying like $30 worth of metal, and having some fun building a frame.

I enjoy building bikes more than riding them, I maintain my BMX very well because I enjoy working with tools, it's just the way I am.

If I trusted people at school, I could make it out of aluminum, and CNC parts like dropouts. You know how stuff at school goes though, "Oh look, that's cool, lets smash it with a ball peen hammer till it's useless" kids at my school are pretty retarded.

I made a mod out of steel once.

It was heavy as hell but kind of fun.


If I may, why dont you pick up a few shifts at a restaraunt durring the week after school and become, less poor?

Sounds like a really fun project. For geometry, I'd start with a monty mod geometry, which you can get that from www.monty.es (http://www.monty.es)! For tubing, the only place I know of is www.henryjames.com (http://www.henryjames.com). If metal is really that cheap in the Hammer, then try to get some 4130 tubes. Use the thicknesses outlined in henryjames.com to to find the wall thickness that's commonly used for steel bikes. Since you're going to make a mod bike, which rarely have seats, you only need to use round tubing for the head-tube and BB shell, everything else could be square. It's probably easier to get square:) I don't know if butted tubes are common for applications other than bike frames, so you may be stuck with straight gage.

I'd use vBrake posts, rather than magura mounts, cause they're cheaper.

I've often though of making my own frame, but when it comes to making the jig and learning how to bend the stays, I give up!

good luck

01-16-2007, 10:59 AM
I had planned on using V-Brakes because of how cheap they are, and how strong they are compared to 990s, which I absolutely hate. Magura's were out of the question because I A. Don't have a set, and B. Don't have brake bosses to weld into the frame.

The metal truly is easy to get, square, round tubing, very cheap, not 100% sure if it's going to be 4130 CrMo, but it is still good steel.

Been really lazy...

I have that Hyper frame all chopped up.

Going to use the dropouts and the stays as is, just bend the seat stays down to a lower level...

So basically I'm trashing the down and top tubes... and trimming off the seat tube... then welding in new tubes... more trials geometry than dirt jumping like it used to be.

My manufacturing teacher wouldn't even sell me this 5 foot long piece of tubing that nobody is using... so now I can't even save the trip to the metal shop and like $5 for the tube.

I just need to buy some tubing... and swap some parts from my Powerlite P-17.

I might need a set of bars... not sure if I want to make my own... it's easy to just run a straight tube... but I kind of want some curvature.

I don't like those 990's... but they're going to have to do, maybe I'll grind my rim very lightly so they grip.

I was kind of wondering why people recommended a Monty geometry... are Monty's not a little short? Just by visually comparing to others.

short bikes give u lots of pop so it takes like no effort to do stuff, but long bikes take more effort but ultimately let u go a lot bigger. if your bikes heavey u probablly want to do big moves

What's the geometry of a Zoo Python? I want to build it like one of those, minus the chainstay obviously.

Borgschulze
01-19-2007, 12:58 PM
I got a 4' 11.5" piece of 1" diameter 2mm gauge tubing.

Got it from my Manufacturing class... it was behind all the other metal... I snuck out the back at the end of class... so nobody is even going to know it's gone.

The piece I asked if I could have or buy was shorter... so this is a better deal by far :)

I just went to the metal shop with my Mom. She bought me a 6' 11" long piece of .083" wall tube. That piece of metal cost... wait for it... $5.70... they have a $5 minimum, so I could have gotten 8' for that price if they had an 8' piece around. They normally sell 12' long stock, but I didn't want that much, so they offered me that piece.

I would really like to find out how long the down tube is on a Zoo Python, or a similarly long mod bike. I would also like the weather to be warmer... because I'll be welding this in my garage... which isn't exactly any warmer than outside... by the way, did I mention I'll be squaring this up by eye, because I'm just that cool.

Probably going to use some steel tubing for handle bars too... unless a friend of mine is willing to give me one of the like 10 crappy mountain bikes in his garage.

:momaru: i want to see this bike when its done

Don't worry, I'll post more pictures when it's built. (Soon after I find out how long I need to make the down tube.)

I'll be using that Kenda Kinetics (20x2.35) tire on the rear of the bike, and probably a bald Max Daddy on the front, or a Primo Wall. Most likely won't have front brakes either... but I'm not looking to do anything on the front wheel... that stuff scares the shit out of me.

Not to dampen your spirits about this project - which sounds fun - but my honest feedback? You're building a bike frame without a jig or a clue.

Now for the helpful part:

If you actually plan on riding this bike, which you may or may not - might just be a fun project to build a bike, you really ought to do some research, and build yourself a decent jig (you can find instructions for a plywood jig online). As far as mitering goes, metal holesaws work just fine, but you'll need to figure out a way to clamp them at the correct angle in your drill press/bridgeport.

Um...yeah...good luck homey. With tubing that thick, amperage is your friend...

Man, if I was planning on seriously riding, I would probably just save up for a real bike. I just want some fun for a few days...

You guys probably all have higher standards than me.. but comparing where we live... my area is probably a ghetto as to your maybe suburb or upper class city. I know one city over... in Burlington.. they think Hamilton people are poor, and they won't even come to our area because they think they're going to get stabbed when it gets dark at 5pm... I know this has nothing to do with me building a bike... but I just wish people would stop with the negative comment. I am just looking to have some fun, and that's what I'm going to do.

I think I'll make my down tube 24", to compensate a little more length from having crappy forks. I haven't decided what I'm going to eyeball a heat tube angle at though... probably close to 70 degrees though. Bottom bracket around +10mm?

I think it's better to build something solid and alligned, and to take your time with it, rather than to just have fun for a few days. If you take your time, the end result will be your fun.

Stop complaining, Hamilton isn't bad. I must admit though, you dont want to get caught walking alone downtown at night in the irish district..

Well I ran out of welding wire... only a small spool of it was in my welder. It's a small MIG/Fluxcore that my Dad bought me for Christmas.

I got most of it done... and I do admit, this picture looks weird, the seat tube is actually directly under the top tube... it's like some kind of illusion.

http://i124.photobucket.com/albums/p37/Borgschulze/DSCF0092.jpg

Yeah I know... dangerous seat stays... I don't know what I'm doing with them yet... probably just put some old jeans over it with zip ties... or find some kind of rubber to wrap it with so it doesn't cut my leg off if I fall on it.

I did a good job eyeballing it. The frame sitting flat on the floor without wobbling... the forks are maybe one degree from going straight forward. I'm also lazy and don't want to make a jig, I'm too stubborn to go through with that.

I'll have to see if Mommy will buy me some more Fluxcore wire... or maybe go to my Dads and see if he will. I've never checked out how much it was, so hopefully it's cheap enough to finish this project within the next few days.

Dude, that looks pretty good, I'm impressed it came out looking so nice.

One thing I'd be a bit worried about though is the rear triangle. The bend/weld in the seat stays looks dangerous. Not from the fact that you could cut yourself on it, which you could, but when you're backhopping there is a lot of force pushing the rear wheel up. I'm worried your frame will fail at the intersection of the seat stays/seat tube/top tube or at the bend in the seat stay, or both. I'm no expert, but I'd recommend a gusset or something in there to strengthen it up.

I know how much force there is back there because I've cracked my Monty cromo frame, and I'm not a big guy.

Other than that, like I said, it looks good.

Borgschulze
01-19-2007, 10:09 PM
I could weld another post in there, from the bottom bracket to the angle at the seat stays.

Tomorrow I'll do it when I get more wire.

My BMX bars are too short, they're chopped down to have my break lever on the angular part, and my hand just fits the width between the lever and the end of the bar.

I might be trading an old 120gb hard drive for a crappy mountain bike.

I can use the bars, brake levers, brakes possibly, and maybe Monday if I plan it right, make an adapter for the bottom bracket so I can have a better gear ratio and better cranks than a one piece.

01-20-2007, 04:28 AM
I dont think that rear triangle will matter because its so long you'll be leaning too far forward to reach the bars and wont be anywhere near hitting it anyway!

Henri
01-20-2007, 05:00 AM
wow, thats long! i'd weld some gussets near the bb seatstays area like the coustiller, old pitbull have. and you should modify the brake mount to fit a v-brake, the u-brakes dont give a grip and are hard to pull from my experience. also the stem is really low. good luck!

Dang!
01-20-2007, 10:04 AM
I think it's great, well done so far-
I agree that the seat stays could use a gusset or two, the head tube area could stand to have some gusseting as well, a lot of stress will be realized at those welds because of the geometry and length of top and down tubes, it may help the aesthetics a little too.
Also be careful of the MIG weld, as they have a tendency to look better than they function, the weld zone also reaches a hardened state more frequently than with some of the other welding processes (I am not sure if you have ever tried to drill through a MIG weld, some times you can, some times you break the bit), the concern will be that at a stress zone or point of moment the hardened area will not flex like the sorrounding area and develop a stress crack, causing the weld to fail.
Don't let any of this impede your process, just be aware.
All these discoveries and failings will only help to make you a better fabricator.

I've been welding occasionally for the last 3 years, I know quite a bit, but I also realize I'm not the best welder. In the case of this frame, I feel I am greatly held back by the use of Flux core wire. My welds on projects at school are a hundred times more pleasing aesthetically.

I have tried drilling through welds before.. and have broken a so called Titanium drill bit doing so.

I might gusset the rear if I find it flexes too much when I hop. I'm not planning on doing any big drops on this bike, so I doubt it's going to be a problem. I did jump on the top tube of the bike in my garage today after I finished welding it. It's not flexing from what I can feel, very solid, but I'm not exactly hopping on the back wheel...

Once I warm up from the cold, I'll go bug my friend, see if I can get that mountain bike for parts, I'm hoping it has a one piece crank, or the same fitting as the one pieces use. He has three or four bikes in his garage, so hopefully one of them I'll be able to use the cranks.

What colour should I paint it? I'm thinking orange.

Maybe I should have just chopped up my Powerlite? I like it too much to do that to it, it's served me a good five years with only changing tires and the cranks coming loose. Plus the frame is too narrow in the chainstays to fit a tire any wider than 20x2.1.

EDIT: I forgot, I broke two crank sets on the Powerlite.

I don't mean to disappoint, but, as someone who IS a certified welder, don't expect to be rolling in the big dough. I made more working at Bath and Body Works than I did welding. It doesn't matter if you pass the test with flying colors - if you don't have experience in doing it (like, 5+ years) forget about getting a job that pays $25/hr. Tests are also expensive, at least my TIG cert was.

That being said, if you want to do it, go for it.

I received an old Raleigh mountain bike.

Tons of Shimano parts on it. Pretty nice bike I might say for free.

Quick release hubs, V-Brakes front and rear.

I almost think I should scrap what I built and try trials on this bike.

I'll post pictures after school.

01-22-2007, 10:20 AM
the geometry on that bike you built is retarded(the welding itself is nice, but the geo is truly reaterded, it's way too long and the front is waaaay too low + mod bikes have a bit longer forks than bmx bikes)

you might be ok when you put a 26" fork on it(try that raleigh mtb fork on it) but it will won't be all that good.

but if I were you i wouldn't give up - you have the potential to build a nice costum frame, just TRY to make the geometry correct.

wheelbase should be around 1010-1040mm, chainstays 360-370mm, headangle 72 degrees and about 40-55mm bbrise. if your current rear triangle has reasonable cs lenght(less than 380mm) then you could still use it and at least try to make some kind of frame jig for it before just starting to weld randomly. I agree - building stuff yourself is fun and you could most definetly make a rideable mod for almost nothing, but THINK before you weld. there must be a reason that mods have max 1045mm wheelbase and have higher front ends, right?

Nice welding on the mod but it is to long and low. Way to hard to pull up the bars. That mountain bike is a way better bike to learn trials on. Have fun.

I tried some hopping on it, couldn't even do two... it's so short wheelbased I can't pull it up.

its easier to pull up on a shorter wheel base. shorter lever requires less force. i know when i got from my mod to BMX bike i loop out like a mad man cuz its so easy to pull up on

I came from BMX to that Mountain Bike and I can't pull it up at all... can't even bunny hop...

I can clear a recycling bin on it's tall end on my BMX.

juhan: that fork won't fit on the mod - the fork is 1'' threaded

If you thought a bit you'd notice that he posted the pic AFTER my post so I couldn't know that.



The reason why you can't pull up the front end of the mtb is because you have bmx background - bmx is the bike that's easyest to bunnyhop(the front comes up really easy on bmx bikes) and biketrials bikes ride VERY VERY differently from bmx'es.(so do mtb's)
you should start to learn some balance(trackstand) on the mtb and then start trying to backhop(there are loads of topics on how to start learning trials so there's no point in going over all that in this topic)

anyway good luck, and i hope that your next frame will be better suited to trials.

I can trackstand (Still stance) on a unicycle, easy skill.

I can trackstand (Still stance) on a unicycle, easy skill. Its actually is very important to learn, I hope you get the basics as easy as you say. But I think they are much different.

I tried to do some stuff on a mountain bike like that when I was on vacation without a bike, same type of brakes (cantis) it was quite funny at that time .. back then I couldn't even backhop. But I could say that it sucked even for a beginner bike. But I saw some russian video where they rode trials on mtb's like that.

Maybe you could replace some parts like vees etc.

Yeah, I can trackstand on a bike easier than a Unicycle.

If the damn snow would stop I would swap the bars to the mod I built.

Have you ever seen a raleigh with a 1 1/8'' threadless rigid fork?

I just wanted to save him some time in case he didn't know and wanted to try :dunno:

I am well aware of which parts will work on what.

I didn't say anything though in my post, so that left the opportunity open.

I don't know... I could hop better on a friends Norco Kokanee... Maybe because it was aluminum?

I think it's really cool that you've built your own frame with the limited material that you had. Stick with it, and as someone else said, it will probably make you a better fabricator in the end.

With that said, you seem to have a chip on your shoulder, as if you already know it all. Be a little more receptive to some of the comments, and pay particular attention to our warnings. While it is indeed criticism, it's constructive; we're looking out for both your well being and your enjoyment of our sport.

Good luck on the project!

Lots of people say that, it's because I don't use "Smilies".

In person I never get that, only on the Internet.

Buy me a video camera.

It feels like I'm riding the mountain bike, just that I'm lower to the ground.

The brakes work very well.

So yeah, I just threw on the BMX stem and bars...

It's too cold for me to ride really... I get really really slow reaction time in the cold.
