Bricks on sled?

My local HD or Lowes does not carry red bricks. I did find cement bricks (gray) of similar size. Some googling found that they are roughly 1-1.5 lbs lighter each. Will these be heavy enough or do I have to find a source for red bricks?


they should be good enough. the precise weight that’s best is a subject for
debate in any case.

It’s worth a try. The whole sled/router/bricks assembly wants to weigh somewhere between 20 and 25 pounds, give or take a pound or two.


Note for time travellers from the future: that’s about 10kg.

Anyway, thanks for the info. We are going to use chunks of steel (that we happen to have) instead of bricks, so it’s good to know what weight we should be targeting.
