This is what is going on with this machine at this point. This is a flawed part because; too much hurry; forgot details in part;  forgot to tell pp which side of line in a segment, etc, etc, etc. But its working....and pretty well at that!

This is fruits of the labor (and advice and troubleshooting) of the good folks here on this forum. God love 'em! They just blindly keep plugging advice, sincerity and good cheer into the posters here...and get things working.... thank you all very much, names are known.... and appreciated.

Here is a photo of a much hurried part to just make something right away......!

Hi, Bill

Look's great, Beat's cutting Air or nothing at all for sure, Next one will be perfect, Wooo-Hooo.

Chip

Hey Chip, do you recognize what this part is?

Bill C.

Heeeeey ,

 It's the drive side of a Harley engine case.
And , a nice job it is.

Ed

Yes. The intent is to cast these cases. I've straightened up the programming on this side to do another one and the cam side is nearing completion. Have a full plan set in CAD, just need time to  make the parts. 1.25" bore X 1.443" stroke - pan bottom, shovel top.

Very interesting project Bill , as I use to work on the full size HD.
Don't forget to keep us updated. Are you making all the parts for this project ?

Ed

That is realy nice machining  .

Marcel

Yes, I will keep updates coming. This drive side case part was finish cut radially with a 1/8 ball at 1/2 degree steps. The next one is programmed for 1/3 degree steps to get a better initial finish (don't like sandpaper). The only parts that I have purchased so far are some ball and needle bearings, and the needles will need to be modified.

The crank is assembled as the early HDs were so a hardened crank pin with needles is what is intended. The forked rods will need to be tool steel too. Scaling the engine has required gears of an oddball diametral pitch so I must make them.

Too many of these hobbies and too little time to devote to them. This day job is really getting in the way! This is why I stopped and converted a mill for CNC because there is no way that these patterns can be made as accurately as this by conventional methods. I've tried...

Thanks,
Bill C.

KeyCreator....Toolpaths are complete. Part coming!

Looks real good Bill . but wheres' the cavity for the rotary breather?
Just wondering.
Whats the scale?
