Does the roller start and stop with a foot switch? Dang Frank, powered and geared, that thing must be a beast. Our work manual roller would only do 1/8th inch. I never tried to max out the power roller.

No I had built the power unit for other applications and I used a spool valve set up with 3 spool valves. Rather than strip the power unit and change out the manual spool valves for solenoid operated valves I just capped off the 2 extra sets of outputs the pump and motor is a combination of salvaged parts from a couple of automotive lift power units the 3 valve bank valve is salvaged from an auxiliary hydraulic circuit off of some machine I had disassembled the tank for the power unit was a 12 gallon barrel no idea what it was originally used for I bought a whole pallet of them years ago the cart is salvaged from a small pressure washer.
The hydraulic motor that powers the slip roll is off of a zero turn mower.
Getting to the guts of the slip roll the frame was made out of salvaged beams and other steel the bearings were salvaged from High line stringing pulley assemblies the 2 main rollers are 6" sch 80 pipe each having 9 2" thick disk inside of them on a 2 3/8" diameter shaft turned down on the ends to fit the 55mm bore of the bearings. the top roll is a single solid 3 1/2" diameter shaft salvaged from a cotton gin turned down to 45 mm and 2 bearings are fitted on both ends the adjusting screws were made from a 2 1/2" threaded rod Yes it is a beast but about the same size dimensionally speaking of a commercially produced unit of comparable size.
My only reason for building it was because a friend of mine had asked me to exactly duplicate the air tanks for an antique truck he was rebuilding I told him I could thinking I could find a metal forming shop with the capability to roll the cylinders for the tanks to the dimensions required. Sheet metal shops couldn't roll the thickness or the lengths I needed and larger plate roll shops couldn't roll down to the diameters I needed or wouldn't even talk top me for a production of just 3 pieces and there was no tubing made of the correct OD's I needed let alone the proper thickness I could find some that was way too thick like 3/8" with the proper OD or some that would have been way too thin after turning down, the thought of having to turn down tubing 44 inches long to wind up with the proper OD sounded silly to me plus I would have had to weld a faux seam weld to make them perfectly match the originals
Hence
