Chuck,
Wow, some very nice machining   :) :) :)

Just wondering is there a reason to use magnesium for the block?

Thanks, Dave!  I used magnesium based on available stock.  I didn't have any aluminum the right thickness, only the magnesium, so that's what I used.

Looking good, there is always something fascinating for me with V8's. I'm looking forward to watching this one grow.

Coming along great, Chuck.  I like the way you chose to remove the stock from inside the crankcase. 
Is this engine going to use your special valve setup?  (Forgotten what you call it..)

Thanks, Dean, yes this engine will use my slave valve arrangement.  Adds as much to the sound as to the operation!

Thanks Stew, always a compliment to know your watching...

Thanks, Nick, I've been having a problem of my own this past few days.  The better half has taken over my shop to paint a piece of furniture.  I can't make chips until she has it finished and back in the house.  Hopefully just another day or two!

For those of you who may not have seen my opposed 4 cylinder engine, this V8 will use the same valve set up and will be a 4 stroke.

It ought to be quite something to hear running then, Chuck.  I've seen a few of your other engines that use the slave
valve, and it really makes a realistic sounding pop on the exhaust.

I messed up one of the connecting rods trying to make them prettier, so I decided to remake all of them.  Tonight I was drilling the pilot holes for the rod cap screws and broke my only 3/64" bit.  Had to order some new ones so the project is on the shelf for a few days.

In the meantime, I'm working on my own design for a model 2-stroke horizontal oil field engine similar to the Bessemer.  Current plan is for a 1.25" bore, 1.75" stroke, 9" flywheels and hot tube ignition.  If I can't get the hot tube ignition to work, I'll fall back on spark ignition.
