Thread: 20 inch Disc Sander

Greetings Chaps. This has been a work in progress for some time now. It is almost impossible to procure a reasonable size Disc Sander. So a couple of years ago I started to build one with the view to making Foundry patterns. It is now approaching completion. The pics were taken today and it is not complete. The Disc is 3/4 " plywood this is directly coupled to a 240 volt motor as per the pics. Because the disc has a velcro backing the table has to be able to be moved back so it is easier to fit the sanding discs in place. This is done by loosening the two vertical pieces and moving the table back. When the table is pushed back it should return to being square with the disc. As I use tapered blocks to get draft on the patterns there is no need for the table to be tilted. I have yet to place a guard over the edge of the disc. This also assists wit the dust suction. There is also a wooden box under the table to help with the dust collection. These beasties make lotts of dust. Hope this is of interest yours 4-6-4
