How to fishmouth tube???

[ElChupacabra]

So Ive just been using a grinder to fishmouth tubes for custom building. I was just curious if anybody had a better solution. I know you can use hole saws to do it as well in a drill press but it seems like youd need an elaborate clamp system to hold the pipe at the right angle and such. Post your setup if you have something awesome or just shoot me some ideas. Thanks!

Harbor Freight has this for $49.99. I've been meaning to get one.

Ive used one of those before, and they work awesome! if you notice the clamp is adjustable for different angles, makes life soo much easier

Have you got one, Mitch? I might have to come hang out in your shop for my next build!

No I dont have one, but I plan on getting one soon along with the tubing roller. Maybe a Christmas present to myself :wink:

Since I cant seem to find any cool bikes, Ill just have to build my own :lol:

We have one that we used for build our dunebuggy and they work really great makes it alot easier to weld the tubes together, haven't tried one of these yet but I think it would help out quite a bit http://www.summitracing.com/search/Part-Type/Tubing-Joint-Template-Tools/

Cody,

You got a buggy too?

Ive got one that needs finished, custom made 4 seater, me and a buddy built up the frame almost 10 years ago, kinda lost interest so it never got done. Ive got all the parts to build a 2180 and a set of 48IDA's for it. 6 rib bus trans, suspension seats, aluminum front, SR1 paddles, etc etc. One of these days I gotta get it finished up, or trade it off for something else :lol:

Yeah ours is supposed to be a motorcycle powered mini buggy but it has Subaru motor and tranny in it need to tear it apart and paint it but it runs really good heres a link to my youtube account which has a few videos of it in action http://www.youtube.com/user/400redrider

the other day i ran across this site where using a hacksaw and a round file is described. she drew the miter on the tube and went at it.
