Paul:

I trust you got Tracey's plate OK?

I'm ready to order some 4130 tubing if you could let me know what
diameter and wall thickness?

Also, is the final Cozy IV engine mount design finished?

Note, I do have Jeff's plate now---------------- with an RX-8, 6-port.

Thanks and regards,


Richard Craig

Yes I have it thanks.

I order 4130  tubing from AC spruce. I pay the same price as everybody else.

Can you advise what diameter 4130 tubing to use?

Can you advise what wall thickness to use?

Thanks and regards,

For lower tubes that are under compression I use 1 inch dia. .049 wall.
For upper tubes 3/4 dia. .049 wall but to simplify the universal mount
I use one inch upper and lower. Adds very little weight.
I have a bunch of tube ends made on an NC lathe.
