Sorry I took video of the whole process but my editor doesn't handle 1080p so I can't edit it yet, I usually do 1080i for editing but here are the pics I took anyway. The light WOC seems to be working out ok but it takes awhile.
Stock begins as a rough bar of steel and is then face square and smooth
Bar is cut into 4 pieces 1x2.25x2.5
Rough cut sides of the bars are then faced to the same dimension
Rough stock pre-drilled then milled out. These started from 2 of the solid blocks of 4140HT
Next flip the parts and repeat for the next holes
The final roughed out parts. Although I only did two here I plan on doubling up and doing 4 at a time.
Now for the fixture plate to hold them
Here is what the plate looks like with the bosses finished. I removed .0001 inch at a time from the diameter of the bosses until the parts just press fit on so there is no play whatsoever. They just barely need to be tapped on with a hammer to seat.
Here is what it looks like with a part secured on the bosses. I still need to drill and tap the large bosses so I can bolt the parts down.
Yeah I know I should probably center the vice on the table or use two of them to support the overhang but the fixture plate is 1 inch thick of hardened steel so I haven't found it to be much of an issue yet.
