Those 1/4" plugs look very deeply recessed. How will you screw them up and connect the HT leads? My Triumph Dolomite Sprint required a special thinwall socket for plug changing and some strange long reach plug caps.
Best regards

Roger

Thanks for looking in Rodger,  There is enough room.....JUST!!!...... to get a reduced OD socket in...5/16 hex  (8 mm) with a 7/16 socket counter bore...  ( 11.1 mm)   I won't be putting the plugs in with a breaker bar I can assure you!!!....

That is why I was looking at 10-40 plugs so hard....but the value of 1/4-32 is I can get it started on glow plugs as a phase 1 effort, and then mount up sparkplugs later.  Thanks Vixen for staying on my backside and making sure I could do this.   It will help with debug later.

I'll be running it regardless on E85 with a small amount of oil added...as it will run well with either glow plugs or spark plugs and RC carbs in the .15 cu in range don't mind running the E85.

A 120 degree connector and a silicone boot should be good for a connection....

Distributors are done....based on Steve's Demon V8 design....I've added a mesh adjustment bushing and a separate timing clamp.   This way I can remove the distributor without affecting the timing

I'll be finalizing the cam boxes, and cleaning up the block internal design next.   I'll be purchasing a carb to model next  It's starting to come together now....

Dave,

This is going to be a very interesting and exciting engine build.  :ThumbsUp: :ThumbsUp: :ThumbsUp:

Will be a welcome change from all the other steam engines.

Keep safe

Exciting - what an engine! I will enjoy watching that get built for sure!

Forging ahead regardless.

I've found that there are enough problems in a project even with good prints at hand. Without good prints those problems become overwhelming. So, good choice.

Does look like a very ambitious project. I hope to look in now and again. Thanks.

YES.....When I'm making parts...I don't like doing the engineering on the fly....I just want a print...with dimensions I need to hit.....

Isnt it?    Thanks for looking in Stuart...I ordered a pair of carbs that I think will work out well for what I'm doing
