Now its time to break out the Grove gear for drilling the weldments. This task is a bit overwhelming considering a mistake here will be quite costly and extremely time consuming to repair.

So I took the fuse off the rottisserie and leveled it out.

I drilled the inner bracket wear plate on the press. Piece of cake with a good bit and Boelube.

Fits nicely.

Trimming the crossmember is essential to fitting the oversized Grove brackets.

Next I clamped 8' aluminum angle to each gear leg for alignment purposes. I have read several write-ups and techniques and I "think" I know how to proceed.
I marked the center of the leg and center of the angle and rested the angle on 2 bolts to secure the angle to the leg. I think this works well.

Then I spent a few hours marking the fuse centerline on the floor so I could take measurements from each angle. It was a time consuming process...I first started with plumb bobs at each end marking the center. then I tried a chalkline between the two. I didn't like the chalkline so I tried a laser line. That works but I had to cover the garage door windows and turn off the lights to see the line. Not a good long term solution. So I used the laser to lay out a tape line. This took time but came out well.

Here is the aft plumb bob through the tailwheel spring bolt attachment hole. I used a spent pop rivet shaft to locate the bob directly in the center of the hole.
My ATC opinion is NOT an official FAA recognized opinion, so any advice you get from me is ONLY my opinion.
