   Look for the older Kodak slide projectors, I mean the 
ones previous to the Carrousel projectors. Most of these had 
manual slide changers which were designed to take glass 
mounted slides which are quite thick. Glass mounts were 
generally held together by thin tape around the edges and 
included a mask. I am not sure about the aluminum mounts you 
mean because the modern mounts, like Gepe mounts, are not 
thick.
   I think you may be having problems with friction rather 
than weight.
