I honestly could not answer the PVC question in regards to twisting torque. I've never seen it tested that way, and I can't say I've ever thought about it in that fashion.
I have beat on a length of PVC pipe with considerable force at times over the years, while performing various automotive related tasks. It seems stronger than I expected.

It does take a considerable amount of torque to initially break the lower bolt loose on a fork that has never had that removed, but nothing I would consider excessive, and can be handled with a screwdriver stuck through the upper hole in my fabricated tool.
PVC could possibly handle the torque, but like Holligl stated it may leave PVC shavings inside the fork trying to use it that way?

Good point, SkunkWorks and Holligl; I hadn't considered the possibility of plastic shavings contaminating the inside of the fork tube.

lots of great advice in this thread!

I used a long set of harbor freight forceps to get down through the spring to grab the damper rod for reattachment of the top cap. to exercise the damper rod all I needed was some needle nose pliers to grab the nut on top of the rod before the spring was in.

I just received the motionpro tool and it seems too short to reach the nut on the bottom of the forks to remove the damper rod. im gonna find out tomorrow if it’s long enough or report back with what I did to make it work. I fear some debris got in the damper system in one of my forks because there is some stiction in that damper assembly. I need to get it out to inspect/clean it.

The motion pro rod works with the forks full compressed, just barely. If you're doing seals and pistons, the damper rod can stay in.

For the debris, maybe fill the forks with fluid and dump it a few times...
And shoxsox are your friend. With the upper and lower apart, you can get the ones that are seamless and slip on instead of velcro and zipper types.

awesome to know! thanks.

I'm sure the debris came from a buggered seal when doing the first fork fluid change. i’ve already dumped and filled the fluid twice after the initial seal change with no debris out. so this is my only hope

I removed the damper to find this little piece of rubber, for reference that is my index finger. the motion pro tool sticks out as pictured when fully seated, I used a small wrench across the exposed end to give me the torque I needed. the rubber bit was causing stiction with one of my forks and driving me crazy.
