I finally found some pin stock material to make mosaic pins and i could use a little help . I am going to make simple patterns for pins and lanyard tubes. With out pictures ill explain the best i can on the variopus ones im making . First one is a 1/4 od, brass thin wall tube with a 7/32 square tube. its going to be a lanyard tube.What do i fill the sqaure tube with to keep the epoxy from filling the area i dont want filled. Also whats the best epoxy for doing this ??? How do and what do i add to get color??? Also would like to know whats the best to inject the epocy into the tubes. I have no vaccum but if i heat the tube slightly im sure the glue should run fast. I would like to have black and red for color any ideas please let me know. Oh I also have some micro tubes that are 1/16 od and i would assume you need a vaccume to get the epocy inside let me know thanks kellyw
