Well I got home early today and decided to make the hub for the Ryobi I mentioned in an earlier post. Digging through the material box I found a hub I had made for another engine a while back that the guy never paid for. All I needed to do was shorten it and tap it again for the Ryobi crank. Took a few pictures for your viewing pleasure. Re-working had been discussed and I mentioned the collet chuck I have and love. Here the picture will tell the story. I was able to chuck the piece on the prop side and had less than .001 TIR for runout. Then you can see the way I tap with the tailstock. The tap wrench mounts in the tailstock chuck and works itself along the shaft that holds it into the chuck when the handle is turned. Also shows the keyless drill chuck I use most. Another picture shows how I QC the work. I set this up on the Bridgeport table. Just lightly turn the shaft and watch the needle. Needle only moved a half thou or .0005 all the way around. Meaning I only have half that when running on each side of center. Next picture shows the hub on the Ryobi. Last picture shows the bench centers I bought a while back, I can use that to do the same thing as the V-block setup. I also have used it to check hubs when the plane engine has had a crash. Of course one could still use the V-block for that.
