yeah man, i don't know if you'll find your answers here but it's certainly worth the read and i'd bet everything i have that someone posting in this thread knows the answer and would willing share it with you.


Welding what do you use? Recommend?

peace, bozo

 

[builder bob]

thanks i'll look through that

I just bought a new snowboard so I guess I won't be getting a welder any time soon.

 

[builder bob]

great news! there's a guy close by who is giving away/selling at a low cost all of his welders and he said he'd teach me to weld!

ok so I want to build a bike like the one in the pic. to do it I need to stretch a bike frame a foot and drop it to 6 inches higher than the tire. I have a 4 cycle hausheng engine that runs great and has not been broken in. problem is I don't know how to weld yet. I want to use a 7 speed hub so I can keep the engine at a lower speed. I also think I have to stick pedals on it some where to make it street legal in MA. I know basic machining but haven't gotten my lathe running yet. I will be making parts for the engine and a custom muffler.

Thats my bike!

seriously?! that's awesome! I love the bike! is it comfortable to petal with the petals in that position?

 

[Choppercabra]

As comfortable as it can be being stretched. It is for me.

 

[builder bob]

ok cool, can't wait to get a welder and start making my own version

 

[Choppercabra]

Here are a few in progress pictures. i thought I had more pics. I think i deleted some.

Here is another I made with a mens beach cruiser.

you're really good at stretching bikes! where'd you get the material you added in?

 

[Choppercabra]

Go to your local metal supply store. I just use 1 inch mild steel tubing and I believe 3/8 tubing for the chain stays. When you stretch the chain stays you will need tubing the will fit inside the 3/8 tubing for inserts. Need that for strength. If you are not sure the size tubing you need just take the frame with you that your are stretching and match up the size.

 

[builder bob]

sadley I don't know of any metal supply store near by. only have a few hard where stores. what is the wall thickness of the tubing you used? think I could get it at home demonic?

 

[Choppercabra]

Not sure what thickness I used. Another alternative is cut up a bunch of bikes and use the tubing from the bikes.

 

[builder bob]

I was thinking of doing that but i'd have to buy all the bikes because there is no dump near me which would be expensive

 

[builder bob]

finally got around to calling about a welder and don't have a super busy weekend so I hopefully will be getting one soon. I also heard about a place near buy that sells metal

Here's a supplier of bike building components.
I don't build my own frames, but if I did here's the place I'd check out.

that is an awesome cite! thanks!

 

[builder bob]

sadly the guy with the welders barely picks up his phone or returns calls so it's taking a wile to get a welder. if I get some of my r/c equipment sold though I can start buying some materials
