Tuber sketch, rate it please.

joints look good. definately make it comp legal.

Ok, made some adjustments to the sketch and mocked up some tubing...let me know what you think..

I'll be adding some supports on the side from the bottom to the roof and some other cross bars here and there to give it strength...

looks nice. when brazing; more solder does not mean stronger bond. Make sure that you are getting good penetration on in and around the joint. Flux is the key, where the flux goes, so goes the braze. You will get better as you learn when and how to apply the solder- I could tell you how I do it, but it would probably confuse you more.

keep at it, looks solid.

you may wanna consider where your shocks are gonna mount at this point.... not a good thing to over look.

 

[Calderwood]

looks cool. what happened to dove tailing the back? you going to have it done for this weekend?

 

[joemomma95]

Umm, this weekend, no way possible...I'm not good enough brazing and I don't wanna rush this, want everything to look and work good.

mrpink, thanks for the tips. I would still love to hear your explanation of brazing no matter if it confuses me or not, I can never have enough info. And the shock mounts are taken into consideration already, gonna put a shock hoop type thing on the front and the rears should hit the bend in the lower piece..

custom tubers

in my opinion a jigsaw and some 3/4" MDF is your best investment for making complicated curves in brake line. You can cut out whatever curve you want out of the MDF using the jigsaw. Just draw the curve out on the board, cut it out, sand it down nice and smooth and then clamp it to your workbench and you have a profile to bend your brake line. I'd used this idea a few times but haven't completed a tuber yet. I'm working on getting my shop together now. I plan on using this idea and then marking on the template what radius it is and keeping them. After a few builds I'm sure I'll have enough templates to make up about whatever radius I want.

Nick....this is a very good idea... i have used it a few times before reading your post...

updates?

thinking the same thing. looks good man.

I am not real sure about triangulating joints, but from what I've heard it adds alot of strength. And it looks to me that you do not have very much trangulation at all. You might want to conisider that. Just look at some other tubers, and it should give you a good idea of what you need to add. Looks good though. It will look pretty mean when its done.;-)"thumbsup"

This is how it sits right now, have been short on time trying to do some work on it..I mounted the first link/panel mount plate last night, definately needs more holes now that I look at it...

Also, would like to hear how people go about cleaning up the brazes, I've had luck with the red(pink) grinding wheels on the dremel but it's getting to the point where the dremel isn't going to reach into some of the places I need to get cleaned up...

To make a uniform curve like in the picture I would use something to make them the same. You can cut a piece of 3/4 inch medium density fiber board at the arc you want and use it. Don't use a hammer to shape it use your hands.

Well, if your talking about the roof pieces then ya you could do it that way...I don't have the patience to do all that though...I used a small propane bottle(camping bottle) and formed them by hand. I taped the two pieces together real tight and bent them to the desired shape. It actually worked out real good and I'd do it again if I had to, experimenting with different objects..

Response- How i clean up my brazes. Ive tried alot of stuff, for me i like to just use the files, round and flat. Then i sand the enitre thing with some tough sandpaper, not sure what grit or anything, just some stuff i already had.

It takes some seriouse time, but if you want high quality work, your gonna put the time into it to begin. If you dont have the time, just remember; You either spend $25 building your own with brakeline/lexan or $300+ for someone elses work.

To late for this advice now,,,but next time grind/clean the joints as you go...it is easier to reach them at that time which you have aleady found out.

Ya, I started out doing that, got tired of grinding/sanding and wanted to do more building. I guess I got the best of myself on that one...I just get to building and I don't wanna stop for anything:lol:..thanks for the help guys!

If you can find a REALLY stiff wire round brush for the dremel, I would suggest that. When I restored my old 20 inch mountain bike, the welds were are rusty and rough, but I got this cool stiff wheel brush for my dremel at lowes that worked great for cleaning up the welds. Also, if you have a large stiff wire brush for like an air powed dremel like thing, use that. Those work great too. I have use my dads on various larger things. Works great. ;-)"thumbsup"
