Unusual machine. Guessing the diameter could have been turned elsewhere.
Carriage looks clamped to bed and cross slides feed in directly. Appears the opposite forming roll is being test fit. This would corrugate serious material. *26 and *24 gauge rolls for roofing aren't half that size.

It looks like a set of reducing rolls to me, as the material makes a pass through each section of the roll, toward the right, it gets thinner & wider...Possibly...

They do not look like steel to me. Does the color suggest they might be aluminum? Compared with what I assume is the steel bearing surface of the shaft sticking out the right side. They cannot go much closer together as those 4 rings appear to be as deep as they can go into the grooves already.

those are ghost bolts for when the hole is bigger then the shaft and bubba forgot to put in a key way.

In CA there is a drag racing team named "Fingertight". One can guess how that was picked.
Knowing how to contact them, I'd send marksbug quip, asking what torque they apply to ghost bolts. If they replied "what size", I'd say "this big".
There I go again, LoL'ing myself silly.

thattel doo. my elbo clicked. hmm....fingertight racing in drag. when we were promod&top sportsman racing about 10 years back (paradise racing) we just called our selvs CFR chicken ****er racing. I dont have a clue where it came from but it stuck.just buddies screweing around I presume. then one day at brainerd for the season opener another big rig pulled in...CFR, they parked next to us...just another day at the races...well 4 days. we just went to have fun for the most part...well we were not there for the NHRA race but we ran it any way we were there for the quick 8 race witch we usualy won or took 2nd.those were more fun as you could really turn the car up and fly as thats what the other guys were doing,not just trying to get points. that car is out west somehwere still flying,I saw it about 2 years ago on utube under 60 foot monster, and that it was for sure. never should of let that car go, the next one wasent my favorite.
