Hi Paul,
The welder came over and we tacked the tubes in place. This was the first
time he has seen my project and he made some suggestions to insure the
mount is safe. Because this is a pusher and the engine is relatively far
back the "column" needs some members to effectively shorten the
length. The tubes are in compression for the most part. Anyway the front
of the motor is now getting cluttered with tubes so I need to decide on how
to mount the accessories like water pump and alternator. Is the 2 groove
pulley on the Eshaft adequate? I think all I need to drive is the
alternator and water pump. How does your water pump differ from the
Mazda? Powersport had a front cover with the crank angle sensor removed
and blocked off ( mount alternator there). Has anyone used a crank trigger
setup on the rotary using Tracy"s EFI controller? Do the sensors mount on
the front or at the flywheel? I think I could squeeze a small alternator
in the stock location but if there is another choice I would like to look
at it. The welder does this for a living and has built chrome molly
structures before like a Tailwind. He also teaches welding at Osh. Thanks
for any help.

Only the lower tubes are in significant compression.
Depends on the tubing diameter you choose. You figure the loads and use this chart
to size the lower tubes. Instructions are on the ACRE NL web site. You did
do that did you not? Before you ordered your tubing? :) My guess without
graphing the loads is a one inch .049 lower tubing will more than
take any compression load your motor is likely to generate.
Well it won't hurt. Not a show stopper. Will add to the cost and weight and
make it a bit more difficult to fit things in.
Don't do it if it makes a mess of the tubes. Start over and bite the bullet
on the tube cost.
My water pump uses the early Mazda cartridge so it should work as well
or better. I looked at the 1.6L Toyota Corolla pump Don mentioned and it
looked a bit small. I tried to buy one in the junkyard but they did not
want to take it off the engine. It does look like my pump with the
water coming straight in from the back side and it is mounted down low
on the side of the block. I have not seen the Toyota 1.8L version yet.
It may be a bit bigger.
