An excellent 'How To Article' is in Shotgun Technicana by Michael McIntosh & David Trevallion. I've done several leather recoil pads for my own guns. I suggest that you use pre-dyed goat skin and not pig skin. The goat skin stretches much nicer and is easier to work with. I stretch the goat skin wet and apply Weldwood Contact cement along the edges to secure to the rubber recoil pad. If you insist on using Barge cement, you can purchase from Tandy Leather. The Tandy brand contact cement also is excellent and you may apply to dry or wet leather. Goat skin is available from several E-Bay sellers. I think that I paid about $28 for the last small goat skin hide on E-Bay.
