You can also cut out a perfect circle out of plywood that matches the I.D. of the drum and use that as a guide for where it needs drawn in. One thought I did have though was to sort of pay attention to both open ends of the drum so as not to create a drum that is round on both ends, but racked out of square.
I have thoughts of inventing something for putting drums in round. I may get my son to weld up some stuff and scour around for a junker that is out of round to experiment on. I was going to use the lug holes to hook up a wagon wheel looking rig that would draw the drum in towards the center from these points. Of course the footprint where the drum is actually being drawn would have a pad to spread the force of the pulling out across the surface of the drum. I believe this would work quite well and very well may attempt to produce a prototype. Now, if one already exists, I am not aware at this time but would love to reverse engineer it and make my own anyways.
Also, I am pondering ways to make it more of a universal fit and less of a drum type/size specific type tool.
This is all just thoughts at the moment and if/when I do put something together, I will hit the site up for someone who wants to be the guinea pig!
