allenwrench,
You got some good advice from herman. The Sherwoods (except the SR1) are among the simplest regs out there. The average 12 year old would have no trouble rebuilding one. Your biggest expense would probably be for a large adjustable wrench to remove the cap and the yoke nut. You could use what is called a "Sherwood tool" in the Caribbean--a straightened paper clip held in a pliers--to pop out the high pressure seat. You can download a service manual from frogkick.com.
With the low price of Sherwood kits, it hardly pays to fool with making your own seats, as the seats last a long time and can be used on both sides. The kits include parts for both stages including inlet screen, star washer, all o-rings, and both (teflon for first stage, and rubber for second) seats. The last kits I bought, about 2 years ago, cost $8 US, which was full retail.
The older Sherwoods had the dry bleed filter integral with the piston, the later ones with the round first stage have it located in the first stage body. The piston located ones will require replacement of the piston to replace the filter. In the later bodies it can be simply removed and replaced with a small allen wrench. The reason I mention this is that if this filter ie partially or compltely blocked, the Sherwood will be a pretty miserable breather, getting considerably worse as one goes deeper.
