I have a question, when building a tuber how do you make a joint twith numorus tubes, one where like four tubes meet?

TMXONR · 10-04-2006, 07:35 AM

I've have never had more than 2 tubes come together, but you could just cut the ends so they would all mate up correctly.

I think he means a Cross "X" Section.

If that is so. Then you will run one solid the full distance (corner to corner) and two smaller pieces that will intersect it.
Making a V shape for the corners.

Well kind of the intersection will have tubes in the cross shape and one sticking perpandicular to them. the problem is how do you braze all those tubes at once. you cant do one and then another cause you would melt the joint for the first, right? i guess you would have to do the rest of the boy and they would hold themselves and you could try to do one big joint. maybe

Try to make a jig that holds everthing together all at once.

A magnet.
I would normally have the frame done then add the braces. also working in different areas so the oposite doesn't get as hot. or braze the out sides first then do the middle piece with all of them meeting.

I think that's 5 different ways so far. Just look at it, think about it, then do it.

If you use silver solder (technically a silver based brazing alloy) then you can get a few different types with different melting points... very useful if you don't have a few '3rd hand' tools.

'Hard' has the highest melting point, 'easy' is lower, 'medium' being in between if (you can imagine)... the only tricky thing is the tubes have to mate PERFECTLY- it flows better than general brazing rod, but it also means you don't have to spend forever filing to get a clean looking joint.

Be careful with the magnet.If you heat it up enough the fumes could make you pretty damun sick,not that I've done that or anything....a friend of mine did....yeah.

I did this joint with silver solder, nothing holding anything, you just have to be quick and careful with your heat but it can be done with some practice.

If you are using an Oxi/Mapp tourch, you can actually control your heated area very well. I can braze second and third joints without melting the base joint.

I tack-weld, then braze.
