So, flat backed it is. Just spit balling again Is the rest of that tank sealed except the front? As in, heat that flat piece you made and blow pressure into the tank. Maybe a damp rag /paper towel wrapped on the tank edge near it to keep that from heating and expanding too 2 Share this post Link to post Share on other sites

To some extent that's the fault of the kit(s) but also, I'm doing a combo that the manufacturer wouldn't have planned. 1 Share this post Link to post Share on other sites

How a bout, Make a thin metal cylinder just a bit larger than what the final cut out shape is, glue a piece to it and do the heat air pressure thing. Then cut out the smaller correct size out of that? Thin aluminum flashing is pretty easy to shape. 1 1 Share this post Link to post Share on other sites

This may be combined with carving from wood/clay or bondo. 2 Share this post Link to post Share on other sites

What about just making a small metal ring the shape and size it needs to be, thickness would depend how deep you want the concave to be. Lay the plastic material over it and heat the center. Push down if necessary. Or heat the material, lay it right on the actual piece and push to concave it. Once cool and hard flip it over and cut out the shape I don't know how soft that material will get Edited 30 minutes ago by wallfish 1 Share this post Link to post Share on other sites
