I've had that site bookmarked for a couple years now also.. Very good insight....and don't miss the other 2 pages on metalforming, I think he also does the windshield opening.
Got some work done on the other corner today, but only after some shelves were put up in the pantry. A quick trip to Lowes this morning, and most of the afternoon was spent making sawdust...
Back to metalwork, this is about my favorite "vise mounted" anvil. 2" diameter works well for hammering around most radiuses.
The hole relief for the other side is tackled, I'll show a bit more detail on the high tech tools used....
Rounded tips on some punches...
3/4 round stock....
Test fit.....
And after numerous times of hammering, tweaking, fitting, trimming, not all in that order, this corner is starting to take shape.....
