I think either way will work. Cutting the bearing edges to 30 degrees is good to do if you have a router and bit or know someone and then round over the outer edge. Just sanding will also do the trick and is probably the cheapest way to go. Johnnistix has considerable experience in this area and hopefully he will jump in soon with specifics.

Come on...you know I will. OK, first off, look at the edge in a dim or dark room, on a table that you know is reasonably flat and level...look for any significant un-eveness. If there is only a mm or less, don't worry as you will likely sand it out. Mark it in pencil if you need to know where the high and low spots are. Use a flashlight inside the shell to see the uneven areas.

Start with a 60-80 grit. On this, I would go for the 60, then 80, then 150, then 220. Don't worry about getting it perfect, this is a bass, not a snare. You want consistent, not perfection. On this shell, it is like a Kent, looks like 2-3 ply with no re-rings, so just go for a good, even edge all the way around. That is the best you can do for this. Allow your hands to guide you, gently but firmly work your way around the shell. count your strokes, 1, 2, 3, 4, turn, and so on. The count is the number of strokes you will make, and it goes very fast, so in about 3 minutes, you should go around twice at least.

Thank you for your advices!

I'll keep you posted how it goes.

Hy Gilnar,I think you are right,Amati did not made 14" floor,but if you could find older Tacton ,they hed 14"floor and it was with re rings.I remember,they were dark red painted inside,and wrap was easy to take off,glued only on few spots for the shell

Dule,

that kit is bad ass looking!

Did they sound any good?

I would love to have that set!

[COLOR="Sienna"]I agree. Maaaaaan, I think some of those ol' Eastern European sets are hella cool.....[/COLOR]

Blairndrums,compare to nowadays cheep sets come from east,yes they sound prety good,but this older Tacton had a slight incopatibility with Remo heads.For example,they counted in factory that 1"=25mm and for 14"tom it was 350mm,but 14" are actualy 355,6mm,and you had a problem that Remo head could not fit in hoop.For bass drum was never problem.It is hard to find them now,but as I mentioned,I think they were one ply with re rings

I "true up"drums in a different manner-4 sheets of sandpaper stapled to a

20X 20 piece of finish plywood that has been checked for "perfect" flatness.Turn the drum by hand against the stapled sandpaper and it HAS to come out flat.Then make your edges by hand or with a router.

That Tacton set covering looks like the surface of Jupiter-WILD!

I do on snares and on shells that are really outta whack, but if they are just only like a hair out on bass and toms, I left the rods take care, but then I have this way of sanding. You have to watch me I guess. The process may seem not quite kosher, but the results speak volumes. I do true my shells, just not the same way everyone else does, always. If it's a snare though, I take all the time in the world to get it true.
