All the directions sound excellent, but I will give you a hint on covering the plugs..drill a plug size hole in a piece of hard wood allowing a hair of gap..you may need to do a couple to get it right, they wet the hide and using a wooden dowl, push the leather in the hole with the dowell and let it dry, glue it over the rubber plug..All wood should be hard and smooth for best results.

Thanks Gents.

I appreciate your time and advise.

Cheers,

Sam
