I finally got the cylinder tilt brackets done, but just tacked in place for now. I had no problems using a hole saw to drill out the 1&1/8" holes for the pin, but when I had to cut the relief angles for clearance, the plasma cutter really angled off on the 2nd one. I should have cut each separately. So I had to cut another plate. Then my guide plate slipped one one and ended up different from the other, and the pin is bit close to the edge, but the pin will be welded in solid all around the outside ends, so won't be an issue as far as strength. Mistakes like this almost always happen when you work longer than you should. I knew I was getting too tired to keep on, but being stubborn got me.
The original cross pieces have to be cut at an angle on the bottom side to clear the quick attach on my tractor, and once I get the lower pin mount plates on, I may remove them entirely.
I wish I had worked even slower so things would look cleaner, but it is what it is. Function will be fine and that's what counts. Plus I'll do some cleaning up before paint and it'll end up looking better.
