There are a lot of double disc rotors being replaced in this area. Let's do something a bit different this month and make something useful using this item.

The discs I have seen have different patterns of bolt holes, 4, 5, 8 so you get your choice. The webbing between the discs seems to beg to be used in some way. Use your imagination.

The hub for my tire hammer was a disc brake rotor. I cut the disc off with a plasma cutter, however.

I use the brake rotors for the bases of stock support stands. See BP0316 for the full construction details.

The Mont De Lancey Blacksmithing Group (Melbourne Aust.) are using BMW brake discs as fire pots in both permanent and portable forges. I would imagine that many other makes of discs could be used as fire pots?.

Great idea, but only if they are single side discs. The double sided discs have the air holes between the discs. This may effect the fire, I am not sure as I have not tried the double disc rotors in that application.

I have built 2 forges using the single sided discs and they both work well. Great suggestion.

Never really looked at these bad-boys but when I look at that pic of the one with the air holes, I see the possibility of a chisle/punch holder when cut in half. Depends on the size of the holes though and I've never tried it. Just me thinking between classes and sleep-deprived.

See Glenn, I would take and make a forge table, but double decked the same width as the outer circimfrence of the rotor. then I would make a reducer to go from between the two decks reducing to a 2 inch pipe, which would go to a blower. Then I would cover the whole bottom of the brake disc. Than I would build a little rim around the outer part of the brake disc, about 2 inches high, with two slots to get longer stock into the heart of the fire. Then fill it with coal and light the fire, with the air coming in from all around the inner bit of the brake drum, so it would work like a side draft but from all around the inner pan.

Sam, how are you going to address the accumulation of ash?


This is not the double disc, but a single disc rotor used as a fire pot.
