Measure the drum at 12 o'clock, and 6. Then measure the drum at 9 and 3. Both numbers should be the same, or at worst, within 1/8th of an inch for the drum to be considered in-round.

measure 12/6 - 9/3 (+) and compare. Keep squeezing until they match.

Measure it........

Yes, John above had the right idea.

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!

I was bidding on both of them.But did not win the landscape drum..That drum was a Leedy bass from the 30's a nice drum...Mikey

I was online & read your posts late last night, only to discover after I had typed a reply and attempted to attach photos that my internet connection had gone down. It's still not up, so I'm answering from work. Do a google search on "pipe clamp" and on "strap clamp" and it will bring up photo examples. After you've applied appropriate pressure with the clamps, measuring as mentioned above is how to check things out.

Hey, what did I sell you?

A variation of your "circle" idea was also offered up to me by the woodshop teacher. His idea was to take hardwood glued together (aka a cabinet door, only thicker) and cut a perfect tapered circle on the CNC machine. It would be cut to size so that it could be gently driven via the tapered edges into the inside of the drum at the bearing edges (I hope that made sense).

jccabinets, if you're reading this thread, what do you think about that?

Hey Bill,

It occurred to me late last night _ what you meant _ D'oh _ because I have about 10 of them in various lengths _ just haven't used them in a while _ as I had first went to using biscuits and then to a Kreg Jig for cutting pocket holes when doing edge to edge joinery.

I'd have to look back on my purchase history because I was on a huge buying spree a few months back _ but it was all kinds of stuff _ a bunch of Premiere lugs, various Pearl mounts, some other MIJ lugs and other assorted oddities and mounting hardware _ I think.

Also an apology may be in order here _ because I may have NOT gotten to sending Positive Feedback _ as there was a sudden and serious illness in the family at the height of all that _ that concluded the Buying Spree at that point and delayed all of my 'Works in Progress' _ drumming projects.

Things are better now though.

I would take off the lugs and use the existing holes for the turnbuckles. I would also "over do it" so to say, so the when you take off the turnbuckles it goes back close to original.

Good luck!
