How can I clean up the mold lines

[Donal Harris]

I purchased this SCABA swage block a few years ago. Rather than wait on a new shipment, I purchased this one even though the two halves of the mold were misaligned. How can I clean it up?  Someone told me a Dremel tool but that would take way to many bits. I tried an angle grinder, but that was difficult to control.

I used a Dremel tool with a barrel sander after a diamond burr. It works pretty good for seams but not for taking off large amounts of material.

I'd use a straight grinder with a 1/4' carbide burr. Usually cleans things right up. Sanding drums with ceramics are also goods.

I'd put a contact wheel smaller than the curve I was working on my belt sander and use a coarse belt to start with.

Once I have built it, that is what I will do.

Die grinder with a burr, small sanding drum on a drill, file, I would try the angle grinder again, with a 36 grit flap wheel sanding disk and a very light touch.  A Dremel would work, but would use lots of little sanding drums, you could use the carbide burrs if you have them.

Good luck

You guys are good, I think I just used files on mine after roughing with a 60 grit flap wheel on the 4.5" grinder...  Took a long time and I got quite frustrated with the poor quality casting.

Now I feel like a neanderthal!

I had mine cast from a pattern I made years ago and cleaned everything up by chipping off flash with chisels (cast iron chisels really nicely) and finishing with coarse files then finer files and a die grinder for the bowl depressions

If it was me, a milling machine.  Chuck up a boring bar in the quill, set the bit for the right diameter, and down it goes.

Wouldn't a Neanderthal have beaten the flashing off with a rock, Ed?

I spoke with one of the SCABA directors. He told me to bring it by and he would swap it out for a much cleaner one.
