Hi Bill

I'm kind of jumping in here a little late as well; but wow! what a cool project. I will be following along with your journey down the Wright Brothers path.

Thanks for sharing,
Dave

Well, it was a good weekend, just not terribly productive in the shop as some other things needed doing like fixing the mailboxwhose post had rusted completely through and it just fell over!!  One of the little projects in the shop was inspired by a picture in one of Thayer's posts...a simple mod to the Sherline vise.  The socket head cap screw was replaced with a molded wing nut and some 10-32 threaded rod, a dab of loctite and a locknut to bear against the swivel insert in the vise. This will save me lots of time as I am bad about dropping the t-handle hex wrench used to tighten the SHCS previously (see photo 1)  With that brief aside, I did get a little more done on the face of the combustion chamber, and made one of the fixed terminal insert bushings that screws into the side of the chamber. These are shown in the other photos. Since the threading attachment is not a quick changeover on the lathe trials of that will wait until somme other lathe operations are done first. Tomorrow I will be cutting pieces for the crankshaft and beginning fabrication of that.

It is for sure Dave, and the other parts of the igniter, valve cages, and valves,springs, and keepers are even smaller...maybe I am developing masochistic tendencies or something  :shrug:

Hi Bill, that is some bit of work. I use my visor are I wouldn't be able to see them. Still following you with great interest.

Looks good Bill. 

Small is a relative term.  One day you'll be working on a part and all the small parts for this build  will seem big.  It's a state of mind. :insane:

This is a very interesting build.

And I know (think) how big that finger is.

That's small work. Looking good!

It's hard to make small parts with big fingers  ;)

Looking forward to the next instalment Bill

It gets hard once it gets parted off and that little man in the workshop thinks it is another trinklet to add to his collection :ShakeHead:.

Haven't had much to post progress wise lately, but have made a start (after a few false starts) on the built up crankshaft. The rather crude raw components are shown in the first picture below. The web blanks were then all milled to size and the two 5/16" holes drilled and reamed in each. The original design calls for the ends to be radiused which is shown in photo 2. All 8 pieces were slipped onto a length of 5/16" drill rod with a secondary rod slipped into the other holes to maintain alignment. Once the first end was done the set up was just reversed to do the other end. The 8 web pieces are shown in photo 3 ready for asembly. The crank pin was loctited into one side of the web, left to cure  (photo 4), and then into the other web using a short piece of 5/16 drill rod again in the free holes to keep the two webs parallel to each other. At the end of that photo 5 shows the 4 cranks.  Tonight I will put in the lengths of 5/16" drill rod  which will space the 4 cranks. The final two end pieces have yet to be made and will require some threading and keyway cutting for the flywheel and timing gear sprockets. All of this i do on a 15"x24"x 1" thick piece of blanchard ground steel plate to hopefully keep everything flat. Once this part of the assembly is all complete each of the joints will be pinned with small taper pins or a 1/16" dowel pin. SOrry the photos aren't as clear as I would like but should convey the process at least.

This is a fascinating build. The quality of these parts is superb. Great stuff - I am particularly interested in your approach on the crankshaft. I shall keep following along. The ingenuity displayed in threads like this is wonderful.

Watching closely and intensely.
I'm very interested in this engine.
