Didn't make it adjustable, if I need a longer one I could fit a different bar to the holder.
I had one that went directly into the clapper of the Logan but the hole in the clapper of this shaper is too far up. I'd have to block the work up off the table to reach in it, thought that would give more chance of movement than the shank extending down.
On a side note, the clapper has to be locked down for the cutter to work. If the cutter is further below the hinge point than it extends forward it doesn't need to be locked down. The forward cutting force has to exceed the upward force.
