Hey Pete, I just found out for the umpteenth time that the same ID doesn't go into the same size OD!!!!!!

I never learn.
Not too tough of a fix but a lathe would have been nice.

Mike, it just requires you to be devious sometimes!

Thanks. I just checked.

My throttle body blank is at Geraldo for final machining. The old guy looks good
and I have a feeling he beat the Colon cancer.🙏🙏🙏.

Ian and I are arguing because I can't get to grips with Autodesk. He refused to
help with drawings. I couldn't find all the materials I needed so I bought a kid's
Math set. Compass, protractor etc.

Spent yesterday doing drawings. Bear in mind
I was educated at a school where we never had shop class. .

We'll know in a few days if the throttle body is a winner.
Old habits die hard. I weighed the blank before Geraldo machined it the first time.
3,3Kg and after it was 2,1. I don't expect it will lose any significant weight this time
around.

Excited and impatient. Got my MoJo back and have to make up for the year I lost.

Do not feel like the lone ranger.  All of my designs are done on paper using the traditional ways.  I cannot figure out the computer stuff, either.

Huge download. Took forever.
I really wish I could master the thing.
I only have 4 more drawings to do on the liner.

Bo, we can't all be PC geniuses. Ian is trying this reverse
psychology on me but when he works with composites he's covered in goo from
head to toe by his own admission. All good brother. Old school works, just takes
longer and in my case a better option. Geraldo is 79 and doesn't use CNC.

I use CAD for everything...Cardboard Aided Design.

As long as it's the thin stuff like shoe box material you're good to go.

Shoe box???  Patti makes me go bare foot...Keeps me closer to home.............

Use the box your Cocoa Puffs come in.

Thanks M.P...Now I have that f`n song stuck in my head :x

[tauruck]

Grand Funk, best band ever. Well for me anyway.

If Patti's got you barefoot then do some Footstompin Music.

That will get that other song out of your head.

Steel solid roller.

   
I've been trying to get info out of my cam builder so I can get the correct valve train but he's not forthcoming.

I really need advice as I have no experience. Is this a good enough unit considering I need close to 8500RPM?.🙏

Thanks in advance.

The folks that made my cams were the same way.  They considered their profiles to be trade secrets.  I had to buy the cams and send them to the fellow who built the valve train and he made the digital profiles for the design work.

I went through the cam thing this summer & found very little interest from the cam companies to whittle me out a grind to my specs to prolong valve spring life, they all wanted to fit me up with an off the shelf cam.
Howard Cams on the other hand went out of their way to come up with a steel billet blank that would take my specs, they had it to me in seven days & charged me the same price as a production grind.
