Nice looking work and presses.
We do right much restoration work.Keep an eye out for cheap,free even....old electric griddle.When painting metal,throw the cleaned and ready to shoot(spray)part up on the griddle.Usually low,but Winter may see it on medium.
You're going to be smiling at the results.Heck we use'm as pre,and post heat sources for Tig welding C.I.(cast iron)....part never leaves the griddle.
They're also used for LIGHTLY heating epoxy spray finishes we use on certain gunstocks and traditional archery bows.As with all airborne,kill you dead fumes...be careful.
Thanks for taking the time to post your pics.
