Now that the gear reducer has been completed, it's time to go around to the other side of the edger and spend some time on the final drive for the saws. I had one set of timing gears and pulleys that were salvaged off some appliance, and they will be the only timing belt drives used on the project. The new reducer has one shaft that extends completely through the leg of the edger to drive the saw blade, and I have to do some very serious calculating to make sure the hole gets put into the correct place. I have ordered two Lovejoy couplings. One will go between the engine and the clutch, and one will go between the clutch and the gear reducer. No O-rings or pulleys will be used at all.
I'm liking this build very much. I wasn't crazy about the o-ring drive set-up with the overhead shafts, gears, and towers, but it did actually make the edger run the way I wanted it to. At least it helped me to establish what speed the various components should be running at. The new system I have designed requires much less power to run it, so I still have high hopes of running the edger with one of my gas engines. I'm glad you fellows check in with a comment occasionally. I've had very little interest in this thread.---Brian
