Is the spur availiable from Stihl?
Not in the UK it isn't. You might get more luck in the US at a dealer with a large supply of "NOS" in the back room.
I will save you a lot of time on the search for an 07S sprocket in .404. The part number Oregon lists is wrong, and you will end up buying a pile of sprockets for an 041 or something.
Bantasaw has them - spur only.
If you want rim/drum, then buy a sprocket for an 070, and cut a few mm of depth off it with a chop saw. I suppose you could mill it if you had the kit. They are dimensionally identical, except for the "depth" or thickness.
that sprocket isnt all that bad......lol I had one onetime that i thought was a 3/8 and i outfitted the saw with such, later to find out it had a severely worn .325 The groves were almost worn through to the other side of the metal.
Can you do it on a stationary disc sander?
Don't see why not - though it might take a while, and you need to find a way of keeping it level.

You are doing a good job. I am sure it will look like a new saw when you are finished.
This thing will be harder to stick in the wood than my 084 was. I did test the fuel resistance of the Urethane paint last night. In trying to get it running, I got fuel on the tank several times. It doesn't even begin to attack the finish. Now that's what I'm talking about!
Can that paint be applied to a case bottom without disassembling the entire saw?
Look at that shine! Painting all these deep compound curves and recesses is a pain.
