Hispano Suiza V8

Good to see you Ron! Boat and H-S engine look great. 

Beautiful Boat and Clinker build too => I'm back in my childhood 
Though Granddads where longer and everything above the waterline was a dark clear lacquer - inside and out.
His also sailed amazingly well with a Johson 5.5Hp outboard and seated 7 person with ease.

Great to see progress on the Engine again

Thank you, my friends!

Building a boat is my favorite way to work with the brown stuff, and this one gave my great-grandfather's planes, chisel's, and other old school carpenter's hand tools (including the oil stone!) a good work out. It is named the "Frank Russell" in his honor and memory, though he passed before I was born so I never knew him.

But I do also enjoy machining and building model engines.

Glad to see you back on the engine   

The boat looks great   

Hello Roger. Thank you!

Continuing to knock out odd little jobs whilst weaving around all the usual summertime distractions and occasional heat induced torpor.

Most important visually, the “monobloc castings” have finally had their ends rounded off to complete the H-S look. I'm confident all critical machining is complete on them, so felt safe removing the square corners and datum edges.

The intake and exhaust ports have been tapped for the manifold flanges, and the intake flanges have been made.

All the spark plug holes have been tapped; 10-40 along the upper, or inner side of the vee for the live plugs, and 8-32 along the outside for a set of simple dummy plugs turned from hex brass. These latter are smaller and look a bit more to scale; I'll probably make a set to install up top as well for display purposes. For the last photo I plopped them into the larger upper holes for comparison with the live plugs. Also a printed dummy manifold is plugged into the brass flanges.

That's looking really nice, Ron! 

I like the 3D printed gizmo on the top too!  Is that a permanent fixture? Or will that be redone in metal?

Looking great Ron. Hope you can steer clear of the heat torpor. (and torpor-edo's) 

A very distinctive engine style, looking great! 

Great look - nice to see progress

Hi Kim. That gizmo impersonates one of the earlier versions of  H-S intake manifold, and yes, I will be fabbing it up in brass eventually. The real ones were heated with coolant water but mine will be rather simpler. Worst case I'll blast it with a heat gun to help keep the fuel vaporized.

Hope you can steer clear of the heat torpor. (and torpor-edo's)

Thanks CNR! If I can't steer clear I do my best to deal with it by retreating to a shady spot or the AC'd house with a cold beer and a good book!

Hi Chris and Per – Thanks guys!

Back on page 6 of this thread is a brief discussion of the clever and patented H-S adjustable valve tappet assembly, and whether I could or should try to replicate it in my build. In the end I settled on a good suggestion from Mike (Vixen) that is much simpler to make and more robust at this size, while still retaining a reasonably accurate appearance.

Now, almost exactly two years later (!!) I've gotten around to making a first sample in metal. Happily it turned out pretty well. Only fifteen more sets to go.

It is good to see that you are progressing with the engine.

Now for a long winter in, hopefully, a warm workshop.

Great looking parts and valve assembly Ron!

Hello Ron,
Good to see you are back in the workshop working in the Hispano Suiza V8 once again.  You've been a long time away.

Also, it's nice to have some i/c engine interest on the MEM forum for a change

Cheers 

Mike
