I’ve had some rings cast, and am now looking into finishing larger quantities efficiently.
Most of the work, though not all, will be very textured.
I’m thinking in terms of a magnetic pin tumbler, and I’m thinking of a model that has a larger (in this case 100 ring) capacity) on the idea that you’re going to spend a fair amount of money in any event, so you might as well spend a bit more and be ready to move to larger quantities.
Every thing I’ve read about these seems to say that they’ll take rings to almost all the way finished pretty rapidly, with only minimal work required after that.
I’m kind of assuming that I’ll have to run something on the insides of the shanks.
One thing that I’ve read is that they leave a flat surface looking frosted. It this something that can be polished up quickly in a second step?
Also, if parts of the exteriors of the rings are smooth, how do the machines leave those?
Lastly, in terms of sanding down the remains of sprues, while I’ve seen fairly impressive video’s of Jool Tools (Made by the manufacture/distributor, natch), I’m not sure that they would be any better than a belt sander. Thoughts?
