Dave,
Take care of yourself. My wife picked up some bug, I seem to have caught the tame version of it. Your progress looks good. So does the dipstick itself thread into the case?

OK got the 1/2-20 thread cut....not without drama on the tap...see notes elsewhere.

The new Nikcole insert worked a treat single pointing the threaded cap.    drill some holes and make a gasket and done and dusted....we'll see how much time I get this weekend.

Hi Dave

Just getting caught up on this project.  All looks good from where I sit.

Had my cold just before Christmas.  Slight fever and chills for about a day, then feeling like crap for a few days more; but it all passed quickly before the dreaded bronchitis set in.  Take care of yourself.

I hope you are going to start the cross drilling by using a center cutting end mill. It will not get pulled to the side as will happen if you try to start the drilling with a standard center drill.
Good luck

Abso-freakin-blutely!     I'm gathering the tooling in one place....looking for a good 0.078" long series drill   I'll start with a 3/32 end mill short series end mill.... :paranoia: :ShakeHead: :toilet_claw:

Just be careful when you break through the bottom. Thats when the drills tend to break.

Good news! I have finished a prototype 10-40 plug. All the tooling is done, all the fixtures are made, and all the Gcode is written. With any luck i'll have 50 in stock by the end of next week.

Nice Job! How was it coming out the bottom? Was the bit a little grabby?

I was worried about that too, but didn't grab in the least..just popped thru.    Second one went in like the first.  DONE.

Now for the key-way on the gear side.

Nicely done Dave. The keyway should be easy after that :)

Thanks for looking in everyone.    Yup...keyway and 8 tapped holes for the counterweights....and done and dusted.

Wait a minute.   The crank pins are hollow...I need to drill them out, and put in plugs...at least on the print I do.

Should be able to do both features with the same set up but with the margin block set to horizontal.   It's already on center.

That should be interesting.....I think I'll make those plugs loctited in instead of press fit....my nerves are on edge already.
