I've finished the second bearing housing:


Then onto machining the counterbores . . .


. . . and making pilot holes


They were finished off on the drill press:


Trial fit:


Then back to the bed rail supports. On the original CAD I'd forgotten to include the radius on the edge of the box section, meaning the threaded holes were on a corner. Drilling and tapping these turned out to be a bad idea so I needed a plan B. So I decided to machine out some pockets and insert some threaded bosses. Here are the bosses - took quite a long time to machine all 16, but they are done now:


Then machining out the pockets:



Trial fit - a gentle sliding fit. They locate themselves, but I'll still knock up a little jig to hold them in place so they don't move when being welded




Still need to finished the other rail support in the same way, then off to a friends to be welded in.
