After repairing the plastic elevation crank on the Dewalt 7790 ras, I recently bought, and mounting the saw on a cabinet I have, so it's table is above, my tall work bench, I realized, I needed to stand on something to be able to adjust the arm elevation.
I bought a couple of sprockets, and a bicycle chain, and came up with this easier to use crank.
It works great. The chain looks skewed a bit, as I am waiting for a bushing for the crank and sprocket. I used a small pipe nipple and it's about 1/16" too small, and sprocket is skewed a bit.
I may figure out something to keep some of the sawdust off the chain. Maybe just a cloth cover, as it doesn't get adjusted often.
