Was stuck in the shop waiting for deliveries. Got sick of doing paperwork so went into the shop and knocked up a third hand from scrap. The 1/4" round came from a mop squeezer already bent to perfect shape, just had to cut it to length. All three points got aluminium bronzed to eliminate sparking.
Deliveries came, too late to go back to site and I missed lunch so what would do you think an aussie joker would do about that? Ah Queensland, beautiful one day, perfect the next.

A few from the week. The first ones were tough. The main tubes were 0.6 mm (0.024") wall. A little nerve racking!

The rest were a little more chill. Typical 0.7 - 0.8 mm wall.

Beautiful work as usual Zank!
0.6mm is gettin pretty thin. How does it go for strength, is there a weight limit for the rider?

Wall thikness dosent efect on the strenght of the pipe, only material and outside diameter. You can apply the same force in pipe or axle... until there is a litle dent in the pipe.


i have made controllarms for race cars with 0.8mm wall thikness pipe, material 4130. Worked great. Cant take any dents, but is same for the stiffness than hevier wall pipe.

Well you're wrong about that. You're just operating at a lower factor of safety. If you did the strength calculations you would know this to be true.

Thats true that the longevity of the part goes down with thin wall, but dosent effect the torsional stiffness much. Not problem @ racing (cars.. bikes..)

Yeah! We got our ASME "R" stamp qual yesterday. This li'l root pass was enough to send the fire marshal and board inspectors over the edge. I then went to lunch with them and the bosses and stuffed myself full. Great bunch of folk.
It'll be 3-4 weeks before we have our certificate and stamp, but code work can proceed.

Great news Steve, well done. I recon the feeling might better than a standing ovation.

Thanks, guys! I have one procedure and test left... One vessel in the queue is aluminum, so I have to qualify separately, and qualify a separate procedure.

Steve

Good luck on the last one, Steve! Congrats so far!

Last month or so I have ore pics of each if anyone wants more

Looks awesome 5th

Some p91 field weld OD prep for phaser ray this is a power house main steam line. The system runs at 1950 degrees at 2400 psi. The weld shot good time for drinks!
