Right...took daughter and wife to airport...bit lonely for a month, but probably I will have have some garage time...
Gave my camera away this old nikon makes really ugly pictures, this piece looks like turd. My apoligies.
Slot drilling was easy. Used just a tad over 5 mm two flute slot drill. 1,5 mm deep cut at a time. I used shop vack and no cutting fluid.
Boltted all parts together and dry tested, so far so good.
There is just one slight consideration left. See last picture.
I'm a little undesided:
* First plan was to drill trough whole contraption a hole for M8 cap head screw and insert the screw from the top. No problem there. Could even make special allen key....but I don't like it fiddly. I dummytested it and I dont't like anymore....
* Second plan was to cut a 8mm slot to the lower ali abutment to allow to insert normal bolt...I don't think it would weaken it unnecessarry.
Original design was such that the screw took a hold from foot and the upper body was just noched to allow use of key.
I take hints how to improve appearance. I'd like arms look better, but I don't like painting them - that would be unpractical. I don't have chemical blackening compound and I'm afraid it would make brass look clapped.
Thank you, if this contraption works, I might be back on track on spotting drill very soon.
