Sanding off a finish
 
I'm planning on sanding off the finish from my LTD M-107, anyone have any idea what grit of sandpaper would work best in removing the finish but keeping the wood in good condition?

Sanding off a finish takes a long time, and is a pain in the ass. Start with the lowest grit you can, until all the finish is off, then work up to ~320.

i did it to an old epiphone V going from 80 grit, to 120 to 220. it took hours though by hand and many passes through with each grit so keep that in mind, especially since you can buy a palm sander for about $30USD.

i expect start off ehavy through the clearcoat then once that's gone, go for light stuff

Low grit till you hit where you want (bare wood, base coat, etc) then higher grit to get it relatively smooth.

Just be careful if it is a flame top, because the top is a very thin vineer (about 1/16" thick)

If you are going to re paint it, DO NOT sand all of the paint off.

If its got a thick coat of poly on there, I'd probably scrape that off before going to sandpaper using a cabinet scraper. Keeps the wood in good shape, but is quicker and doesn't make as much dust.

Otherwise, you'll want a lot of aluminium oxide paper, probably its grits from about 60- 400ish? Higher if you want a semi gloss or gloss finish.

This is not true, if you are spraying a finish or using oil. Anything past 400 grit will be filled with finish. It is a waste of sanding to go higher than that.

If your goal is just to take off the finish and apply an oil of some sort, you might want to look into a stripper. But you'd have to get a stripper that will remove the finish, but not the veneer. I'm not sure what LTD used to glue on the veneer, could be formaldehyde, could be something else. You'll want to find that out before applying a stripper. And if it has a plastic binding, you might want to find out about that as well.

Alright, I stand corrected. Thanks for saving my time. :D

My goal is just to take the body down to bare wood, don't believe there is any veneer under the finish.

Stripper. Search the web and find out which stripper will work.
