OK, Finally felt good enough to get out in the shop for a couple of hours.  I got the shafts for the oil pump done tonight, and made a bushing to locate the bearing holes in the cover, and put in the bearing holes with the bushing and a D-bit.

Turns nice now.   I need to tap the inlet and outlet.  The plans call for #10-40, and I'll probably use that size thread for the spark plugs so I'll get that tap and die and add it to my collection.

No real drama, other than I need more light in the shop.   The eyes aren't what they used to be! :hellno:

I know what you mean about the eyes not being what they use to be I suffer from that also. You oil pump looks nice and you have done some nice work. Looks like an interesting engine we will be watching.

I know what you mean. When I first read that, I read "more light in the soup".
It's worse with the hearing. Sometimes what I hear is funny...sometimes she gets upset.

My wife sent me to get my hearing tested!   I went through the battery of tests at a very prestiqeous medical center...and the doctor said I have good news and bad news

The good news is you have a little bit of mid range loss in your left ear...but not enough to worry about and otherwise your hearing is normal.

The Bad news is your hearing is normal !   ...... :Lol:      He was right!,,,,,that was bad news!

Ordered 10-40 tap and die yesterday... I'll need make a co-bore tool to make a square bottom hole and to spot face the outside surface for a seal washer.

Ok

I got up early this morning and got to work on the oil pump.

I was able to tap 10-40 using a .156 diameter as a tap drill, even though, the book says it should be .166.     

This let me make the hole with an end mill (5/32) and spot face the hole (.25").

I had to deburr the part a bit, but it went back together....I need to shorten the screws....but I'll post a finished photo in a bit.....got the lawn to mow first ::)

OK question to the membership

I don't really want to use a "point" ignition and would prefer an electronic ignition.

Whose should I use?

I can run a two magnet rotor off the camshaft and go from there or use a loss fire system.

Remember you have a Mechanical guy messing with wires......never really a good thing! :slap:

I would go with Roy. He is a great guy to work with and if you need help he works hard to make sure everything works great. He is at the model shows every year.

I have had the basic ignition in the Peewee for about 3 or 4 years now and everything still works great. I did burn out a sensor when I was doing the inital shake down but now that the ignition timing is set and everything is dialed in, the sensors last for years.

Thanks for that Steve!

I think I'll just use 2 magnets off the cam and keep the ignition box seperate from everything else.   I can shield it easier I think if I ever decide to put this little beasty in a R/C tug of something....

The original plans call for a 3/8 plug!   I think I want to use a 10-40  or 1/4-32 plug instead.

Considering the head will be aluminum....I'm thinking maybe 1/4-32 would be a better idea as I think the threads will hold up better...though they're still kinda big...

I think you gave me some advice on this long ago Steve.....so excuse me for asking again.

Don't worry Dave.  It's a common affliction.  As women get older, they begin to mumble.
