Keep a right-angle protractor & ruler with the Hudy case...
When I reset my blocks, I measure the distance between the 2 and use the right-edge to check that its square against the bulkhead.
I try not to adjust the blocks too much, I've fixed them to fit most of my arms. The looser arms just use a washer/s to shim the freeplay; its quicker than readjusting & measuring.
Measure your comm with good calipers across the straight surface
and it'll show up if you've cut it cone-shaped.
