I was finally going to use a fancy cutter….and it was smoked…so I used the lowly hole saw. Yeah, 1” of steel takes the better part of a beer.
This is the main hinge that allows the grinding head to piviot away from the stump, if feed is too aggressive, so one can stop advancing and allow it to “eat“ it’s own weight until it is perpendicular, then proceed.
Not going to insert the oil impregnated bushings until bearing surface tube is welded in place and cooled, then will final ream.
Upside down; however, arranged like this in the end.
Cut the other mid plate mount and a couple of gussets today.
Can see the ”from the back of the tractor” view of the hinge in the last photo. Will be two pins, as a finished produc, just easier than a fixture to align them with 1 piece of barstock.
Had Dad stuff to do again but would really like to take it out for a hot lap before next year, so I knocked out another few inches of weld. Not my best work but should be sufficient.
