Both of these tools lacked a means of indexing the depth of the cloth, so my copy didn't work too well. For years, I used hide glue, cauls, and two pieces of appropriate thickness cloth, inserted into the mortise, caul inserted, and trimmed flush with the caul with a knife. This worked, ok, with near zero waste of bushing cloth, but was hard to gage the depth of the bushing in the mortise. Lately, I've used my old homemade tool, re-modified with ears to index the cloth to proper depth (like the Bushmaster). It's quick and wastes three times as much bushing cloth as is glued in the keys. Unnecessary waste offends me, but the uniformity of the job is just what I was after, so that's where I currently am. I suppose if I did key bushings on a weekly basis I might be doing it differently, since it always seems to take me half a set to get comfortable with it and in rhythm, this is easy and mindless enough a system for me to run it. When I get tired of looking at my funky little tool, or it finally falls apart and dies, I'll probably buy a Bushmaster. So how do you Spurlock method bushers index cloth depth, and are you happy with the result? Ron N
