I have a Delta ShopMaster DP350 Type I drill press in need of a replacement chuck. The current chuck is rusted and I can't open it. Other than this issue, the machine cleaned up nicely, rust on the table, stand, and column has been removed, and it runs like it did when it was new. I think this machine is worth this minor repair... if I can figure out what I need to purchase.
When I started digging into this, I quickly found there are a few choices when it comes to chucks and I have no idea how to select one. Everything on this machine is stock - no aftermarket upgrades - so it would be a good start if I could find what type of chuck was included from the factory.
How can I figure out what kind of chuck I need?
