Started out on multi spindle lathes. Ran thread rolling machines, multi tool chuck lathes, multi station horizontal milling machines.  My favorite was a brand new out of the crate Bridgeport vertical milling machine. Got to set it up from the crate. Was a joy to operate. There were a few CNCs being used. Never got to run them. Would love to go through our old shop today. Technology advance must be incredible. Also was a draftsman for a few years. Many moons ago.

Hey Scoot, were you a manual machinist or a CNC machinist? I have had up to thirty machinist reporting to me but I have never worked full time as a machinist, I did occasionally fill in for absent operators and I developed all the processes we used. Before I retired, we had converted over to completely CNC machining other than a tool room that still used manual machines. 
Did you ever use this trick for making square holes on a manual mill?
Start by laying out the square, then drill a hole the same size as the finish corner radius on each corner, then a hole in the center of the square. Drill the center out with a drill very near the diameter as the dimensions of the square. That leaves just a fraction of the original material to be removed.

Hey Scoot,

No where near a proper blueprinting, just enough to develop the data I need.

Hey Ray. Did you draw up a set of prints for this mid section? Would love to see it if you did. 
Worked in machine shops for about 15 years.
Really enjoyed machining.

Here's a few more details.
The big hole is what everything is located from, it is where the drive shaft goes through the bracket.
The smaller ones are the holes for the studs that will bolt the powerhead to the bracket.



The bigger tapped holes are for the bolts that will hold the bracket to the midsection, the smaller tapped holes are for the original 70 exhaust tuner.





The studs that hold the powerhead to the bracket can't go all the way through the bracket because they interfere with the bolts that hold the bracket to the midsection so they will have to be accessed from the edge of the bracket through these windows. These won't be so deep once the edges are trimmed in the final stages. Two down and five to go.

Ray thx for sharing my anticipation has been building on seeing this!! Always enjoy seeing you make the impossible possible. Very cool.

It’s moving very slowly, I will post more soon.
The engine block does have bigger holes in it now, going on advice from Joe McCauley I’m using 0.030” oversized OEM Evinrude pistons.

Ray how’s this block of aluminum looking?

I’d take one lol that rivet bottle opener is gold mine!!

Bag that up and send it to Terry.  Maybe he can make a bottle opener .02 run.
