ToxicFabrication

for over a year now i have been throwing the thought of building my self a bike around. never have time and could never get the materials i wanted. so finally i found everything i needed. this is no easy task. i used all double butted 4130 chromo tube. every part is made from chromo. frame came in at 4.2lbs which put a smile on my face:updown: here are some pics of the frame before and after welding. most pictures before welding its in the jig which i will keep a secret for now. enjoy!

sweet man! great as always.

I really want to build my self a jumper. my little bro is a semi-pro downhiller and when i see some of the fab quality on bikes that cost 7 grand it blows my mind. guys like you should be doing it, not chinese robots.

perseverance

that looks great, i wonder how it will hold up to some hard street riding. I've broken a couple frames, although i am 5'11'' and 230lbs. It looks really really fresh tho man. What size top tube you got going on? i see you're running integrated headset and mid bottom bracket. Def keep it up man. Btw how much do you think you spent on building the frame?

ToxicFabrication

next up im going to build a down hill bike. cant wait! yeah the quility of bikes has gone way down... hense why i built my own.

its holding up just fine, im 180lbs 6ft. ive been trying to brake it so far its stout as hell. top tube is 1 1/4''. double butted .047-.035-.047. i bought enough to build around 5-7 frames. so i spent around 80$ for this frame. give or take a bit. i also scored this material from a old bike builder so i got it cheap. you can expect to spend around 100-140$ i want to say for all materials for a bmx chromo frame. hard part is finding all the right parts.

Thats just badass!

Boostedld9

Man your work is amazing and that frame is badass!

Detective Coati

Sick work man. I love the raw finish of it.

You didn't happen to get that headtube, seat tube, and bb shell from the people over at Roadkill did you? You know Chelsea's dad started a bike company 15 years ago that made frames?

ToxicFabrication

Yeah I know about all that, but no. They couldnt help me out. As far as i know they really do more of aluminum frames. Race bikes. Let me know

STRATTON

thats awesome. make your own handle bars and forks and it would be ****.

Yes, a very nice jig. I'd say with out a proper bike frame jig, it would not be possible to build a good frame. Actually, imo all manifolds, bikes, anything really i weld in fixtures so it comes out working how i wated it to.

doug118

They only make chromoly frames. Well now they do. Back then it was only aluminum. I've been looking for those headtubes to buy but in aluminum to try to make my own frame. I wanted to have a custom frame made but people want CRAZY money to make an aluminum frame. I actually just got one of the first bmx frames in the world with 20mm dropouts

I've been dying to own a 3 pound frame though!

Furyof4

Looks great! I always wanted to build a BMX too, I spent countless hours of my youth riding around on one of those.

Where did you find the materials?

namewasdallas

thats dope looking, keep up the good work

any distortion when welding the head tube... or head set stem, or whatever its called?been a long time since i was into bikes. Looks gorgeous though, because of this thread I will probably order an extra piece of moly to make a frame with

ToxicFabrication

I had no problems with any distortion. Be careful on the materials you order. It's not just any old chromo tube. If you used 8th inch wall or .095wall for like roll cages you would have your self a 17-20 pound frame or even more. I used very thin wall double butted 4130. It's .047-.035-.047. Plus you need a machined head tube (integrated) also, a machined bottom bracket. Hope this helps.

nemisish20

Can you make another one?

I'd be more than happy to pay you for the frame. PM me

^what he said

unusual71

thanks for the info.
I work at a machine shop, which will be ordering the material for me so its no problem. did you just pick a head set and crank etc. and then machine to fit those parts, or did you copy another bike and then order parts that fit it?

doug118

The bottom bracket shell and head tube were purchased. It's next to impossible to make those parts on your own unless you know the INS and outs of bmx. I've been racing for 20 years and worked for a company that makes bmx sprockets but not even we could have made that exact headtube properly. You could just buy a piece to use a normal press-in headset though
