I need some of the large size fasteners for an old Gulbransen grand missing a leg screw and a lyre screw -- and I think two of the screws on there may be mis-sized replacements.

Schaff says to phone for availability and price, so perhaps they don't have a complete inventory anymore? I'm thinking of laying in a supply of sizes 16 to about 20, in varying lengths, just so that if this comes up again I have something to reach for. The hardware stores around here all stop at size 14.

You can go years and years without needing oversized fasteners, but sometimes all at once without warning nothing else will do. Does anybody have any favorite online sources?

thanks in advance

P.S. Wandering hammers -- good advice all round. I wouldn't stop with the strips of sandpaper, I'd add lockwashers as several have suggested. Then the bottoming wouldn't be a problem, and there'd be some leeway in case humidity changes tend to loosen the screws. In fact, if the lockwashers were installed in the damp season, then they'd maintain tightness through the dry season without letting the wood fibers be crushed when the humidity rose again. I'm assuming a strong weather shift ... we're getting more of that than we used to in Oregon -- summer rains, wasn't our style until three years ago, has been since then.

I get rolls of sandpaper from Klingspor.
www.woodworkingshop.com<http://www.woodworkingshop.com/>

For flat hammer rails:
item # AR20268:  220 grit, F weight paper

For S&S rails:
item # SR98760: 320 grit on cloth
double sided tape to adhere to moulded rail is available at a hardware store as 1/2" window plastic mounting tape.

Washers I use for S&S hammer flanges: Part Number:  98017A624

With the abrasive rolls, I cut long strips, I don't like seams.

Use a small drill bit and make the pilot hole a little deeper to insure full insertion as Marcel mentioned. Washers too.
