Chuck, it's looking really nice.  However, if I may make a suggestion to round the vertical corners of the pan as well as the bottom, it would look more realistic.  Feel free to ignore, comply or ridicule as you see fit.

This thread has motivated me to get back to working on the 4 cylinder boxer version you made a while back.  I just love that exhaust note you get with your ball valve system.  Can't wait to hear how this one growls.

Really coming together now, Chuck.  Your "growth spurts" are very productive.  ;)

Thanks Arnold, Stew, Dave, rleete, Dean... Had to take the day off yesterday to help the kids get their house ready to sell.  But I'm back in the shop today.

Here's a couple of photos of the engine partially assembled.  I took rleete's advice and rounded the vertical edges of the oil pan and it does look better that way!  Had to use a file since I couldn't figure out any other way to do it...





Next I'm laying out the lines and drilling the holes in the head to accept the air supply tubes and the slave valve assemblies.

Glad I could contribute.  It's a fine looking beastie.

Thanks, guys.  I appreciate the interest and the kind words.

One last picture for the day.  I finished soldering the bolt flanges onto the inlet air tubes this evening. 



The flanges are a little bulkier than I'd like, but I'm not inclined to try to slim them down at this point.  Next I'll have to assemble the flange nuts and then put the flange on the bottom end of all the tubes.  I hate it when I get to this part.  One little misstep can flush a lot of work down the drain!

I really like it Chuck!   The look of an old aircraft V8 is definitely there!

Thanks Ron, Dave.

Managed to sneak in a little more shop time this morning.  I got the air inlet tubes all flared with the flare nuts in place.  It was really pesky getting the length on those tubes correct.  There is very little margin for error.  I used a piece of 5/8" thick cold rolled steel plus an .008" feeler gauge blade clamped in the vise as a gauge and filed the tubes to length.  I would have used 3/32" compression fittings if I'd been able to find any, but didn't have the patience to search the internet for them.  I might have gotten by with using a short length of 1/8" tubing as a compression fitting.  Need to try that some day, it would be a simple solution.

Chuck,
Nice I really like the micro flare fittings. Good thing to remember the nuts, I have scrapped a few jobs by forgetting the nut before a flare.

How many times I have soldered some wires together with out the shrink tube, strain relief or plug hardware...I would not mind to forget.

The engine is taking shape nicely.  Keep it up.
