My new to me toy

Guessing he had a bet going. lol. Didn't you say you also have a CNC machine?

 

Not CNC.......yet.

I do have a full size Mill and lathe in the basement already.

I am thinking of converting my mill and my lathe to CNC.

But that is another project for well down the road.

Too bad. I know of a certain part that could be made for a certain control line airplane. :-)

Well I started the cleaning process today.

 

Yuck, What a MESS.

The oil passages in the ways were caked solid so even IF someone tried to oil it, the oil would have never got to where it was needed.

I worked on it most of today and barely made a dent.

 

The last "overhaul" was more of clean off some outside grunge and slap on a coat of paint.

They painted right over the dried grease and built up grinding crud.

oh cheap superglue works better than duct tape and bailing wire

I have been building bike engines and rebuilding machine tools for over 35 years and it is not recommended to grind valve shims due to the fact that you take the risk of grinding through the heat treat making them soft. It is not worth taking the risk. Find someone that has a set you can swap shims and do it right.

The theory is that as long as the unground side is the side running against the cam, it should be OK.

I am also not planning to remove large amounts of material from a shim, maybe a couple thou at most to be able to hit in between stock sizes.

Overkill, yes.

Unnecessary, yes.

Something to mess with in the cold of winter while PMS is doing its thing, yes.

 

If I feel it is necessary I do have access to the stuff to redo the case hardening.

 

I have many other uses planned for this machine.

 

I will need an electroetch or chemical etch marker to mark the thickness after grinding.

It lives!!!

 

Sparks be a flyin.

 

It took a while to get everything rebuilt (all new bearings) then some electrical issues to iron out. But it is now running.

 

I still need to get some accessories for it, like a diamond dresser to square of the wheel, and some finer wheels (the ones that it came with are very coarse).

 

I still have some cleaning and painting to do on the base casting and a few smaller parts.
