Finished the top, applied 4 coats of BLO and drilled dog holes.
Then is was on to the handwheels and installing the front chop.
The next decision was how to attach or lock the wheels on to the acme rod.
I took them to a machinist friend of mine to have the collars drilled and tapped for set screws, but he suggested using a roll pin instead. After thinking about this a bit, he suggested just to go with nuts on each side of hand wheel.
Which is what I ended up doing. Actually it worked out nice because the nut on the inside pushed the handwheel out just a bit more, making it more convenient to turn.
So it works well, with one exception: I did not put bushings in the outside chop, thinking the 1” hole I bored for the 3/4” thread would give it some slop when clamping a tapered leg
BUT…..there’s a problem.
1) I can’t use the dog hole feature now because the chop has too much slop and just angles out of the way.
Rather than mess around with spacers, I’ve decided to come up with a way to eliminate the “chop slop”.
2) I can’t clamp a piece of wood long ways near the top of the chop without some sort of spacer to keep it from racking.
Solution 1: Put a bushing in the front chop.
Solution 2: Some sort of slide or guide rod mounted on the bottom of the chop directly under the screw. This way, I could remove it quickly if the need for tapered clamping ever came up. Drill a hole in the stretcher for the guide rod to move and mount a beefy guide block on the bottom edge of the chop.
I’ll keep you posted on this.
