Need Help With Tank Calculation

Re: Need Help With Tank Calculation
Don't expect too much perfection.
This is what I'm able to do on 0.6mm Ti sheet material. Welding the ring of sections is feasible. All done with fusion welding, i. e. no rod used... Which I didn't have anyway (used thin stripes of sheet material instead)
1mm should even be somewhat easier.
Though I have to admit that bugs are not my strongest side. Connecting them to a flat thin sheet is difficult and will distort the surface to some degree.
At least I have 50 x 0.6 mm tubing here to do some practice before tackling the important stuff.

Even the annealing works somehow...
Unfortunately it's not like on steel - if you rub with fingers the blue color gets pretty pale.

Thanks, Martin!
Perhaps I can design a bung that has an approximately 1mm collar for welding.

Re: Need Help With Tank Calculation
2 or 3 would do the job. 1 would be a bit too thin (and even more difficult to attach ...)

Can your CAD drawing give the angle (for cutting the sections)?Speed Freak wrote:is this what you are searching for?
Dimensions:
If not, I can get pretty close by measuring the drawing itself.
Thanks!
Re: Need Help With Tank Calculation
Oh that's even easier.
Count the number of cuts (12) and divide 360 by that number (=30 degrees).
The cut angle is half of that as each side adds to the total angle. (= cut angle is 15 degrees).
As a counterprobe the total angle is the sum of all involved cut angles (12 x 2 x 15 = 360).

I can actually understand the formula, this time.
Re: Need Help With Tank Calculation
One problem is how to hold the tubing for cutting.
The idea I have is to sacrifice the end of the tubing, and clamp (one end of) it to a wooden angle that could slide through the ban saw. That way, the orientation of the cuts would be uniform. Need a fine-toothed blade since the tubing is only 1mm thick.
Also need to find someone or some place with the tools to do it, like a Miter Band Saw.

Looks good.
Probably just need a mirror polish before annealing.
Re: Need Help With Tank Calculation
How about using pre-formed stuff like 30 deg elbows?

I've been trying to find prefab 30 degree, 3 inch pie cuts, but they're never going to be the correct length.MK wrote:How about using pre-formed stuff like 30 deg elbows?

Ticon sells the same tubing, so I'll ask them about cutting. They only sell parts, but maybe they can point me in the right direction.
Not going any further until the cutting is figured out. Also need to cut a large hole in one tube for the filler neck.
Re: Need Help With Tank Calculation
It was raining outside and I felt like practicing titanium welds
That's the best I'm capable of after not having touched my TIG box for half a year or so.
Its 1mm Ti tubing, 1.6mm needle in a big cup setup with some 14A DC though the inside looks like a few amps more couldn't hurt ...
(Still managed to burn one hole on the invisible side)

Re: Need Help With Tank Calculation
Very nice work, Martin!
Enjoying some time working on the RZV roller. Been getting help here and there from friends, so making progress again.
This project should be my first priority, though. I'll get back on it, and thanks for everything.

Re: Need Help With Tank Calculation
It'll be like carrying an umbrella. If you have one, it doesn't rain!

Should have some more info, soon.
