Wow!  That's an amazing amount of CAD work, Dave!  Very impressive engine.

Hope you get some time over the holidays to make more progress!

Hello Dave,

The CAD model looks great. I like the look of those external oil pumps. Hope you get some shed time soon.

My vacation has been going well!    Stuff is getting done, tomorrow I focus a bit more on the engine.   I have the gear cutter I needed (32 DP #3 cutter) and I have a fixture ready to make to hold the crank webs for final turning.   I'm hoping for a good time in the shop tomorrow.   

I got a phone call from my boss today.....oh boy!.......it was good news though.....A little reward for my hard work .....

I'll need to make a bushing for the gear cutter...it's 1" bore, and my arbor is currently 7/8"

Doesn’t it always happen, I have a drawer full of them!  You’d think one might fit. :shrug:

Really enjoying this build Dave.  Always looking for the next installment.

Productive day in the shop today!     I'll post some photo's and a vid a bit later, but I got the 3 main drive gears cut.   They'll need the bearing diameters finished, but i'll do that tomorrow when I start the final machining of the crankshaft.

Just gears today.   Tomorrow, I start on the final machining of the crankshaft components

The lathe needs a very good cleaning though first.....I could say the same about the mill!!!...
