Re: need glue for most plastics
https://en.wikipedia.org/wiki/Cyanoacrylate ... Cyanoacrylate glue has a low shearing strength, which has led to its use as a temporary adhesive in cases where the piece needs to be sheared off later. Common examples include mounting a workpiece to a sacrificial glue block on a lathe, and tightening...

Re: Best online source for hemispheres?
I did discover one online manufacturer...it wasn't too expensive.I think the 24" dia. acrylic domes were somewhere between $100-$200?I don't recall exactly.The 36" domes were closer to $300.00.The domes come with a flange that (in some cases) needs to be removed.I think they provide the d...

Re: Decals ripping during slide off
Another "just in case" step you can perform (provided you have the equipment) before doing anything with the decals -- scan the decals into the computer. That way if there *is* a problem, you *might* have a chance to create new ones (assuming that transparent/translucent nature of inkjet w...

Re: Decals ripping during slide off
as dizzyfugu stated, how decals behave vary from case to case. When in doubt, try one of the more easily-replaced or less-noticeable ones on the sheet to see how well it goes. If you immediately run into a problem, then putting a clear coat over the sheet to stabilize them is needed -- and you proba...
