Our 8" long radius sanding blocks are made in-shop. We laminate poplar, cut to 8" length, and then shape to popular sizes. All blocks are sanded and ready to go. Great for fret and refret jobs, as well as making fingerboards.
We stock 7 1/4", 9 1/2", 12", 15", 16", and 430mm(Ibanez) radii. Custom radii and lengths available (maximum workable radius is 20"). Let us know what kind of block you need and we'll try to accommodate.
Occasionally there may be a 2-3 day delay between ordering and shipment due to fabrication times. This is not normal, but does happen periodically if someone orders a size that we don't immediately have in stock. Any length over the standard 8" will require 2-3 days fabrication time.
