Not a good idea to be touching the lead, especially with little cuts on your fingers. Wear rubber gloves at the least. If you're cutting the lead with a tin snip you have to be careful of sharp edges etc.
Laminating to AL makes no sense to me. Most of the platters are already AL We have approx. 6mm total thickness to work with. Depending on the table, motor torque etc. I want it all lead + leather.
Contact cement is no good here. It's too thick and uneven. The top surface can be painted, varnished or whatever, but it's the interface with the platter that makes all the difference.
