In general are you bead blasting the parts to get them so clean? Vapor blasting?

I want to tear an engine down this summer to do a cam swap, I don't plan to be Dr. Detail like you however would like to do a little cleanup of the parts.

Yes, I do the plating. I do it for quite a few years now. It's not difficult once it's all set up. I'm blasting the parts first, then polish as good as possible. After that first clear zinc and then in a solution I got from Caswell plating.

The other engine parts like the cam housings are vaper blasted. I use a Harbor freight sand blast cabinet and converted it. It's really worth it. But all parts need to flushed really good. I also remove plugs and make new ones.

Here are the fuel and oil lines for the cam housing after assembled.

Looks mint Carmagic, AKA Dr. Detail!

I tried the Caswell plating, and my results were so-so. I probably needed to spend more time on the details. I do use the yellow zinc chromate on silver hardware store fasteners though. Yours looks factory, so good to know it 'can' be done. Any details on converting the HF blast cabinet to vapor blasting? My cabinet still works after all these years, but tends to make a mess with sand debris (mostly from the vacuum exhaust I think since the cabinet is sealed 12 times over). Does the vapor blast cabinet completely replace the traditional sandblaster in your opinion? In order words, if I were to convert mine, would I miss the ability to do traditional sand blasting?

Tom, I have a dry blast cabinet, which I built myself, also larger.

There are a lot of videos on youtube where I got my info from. Here is one

But I made this quite a few years ago. Most add a vacuum, but I found I don't need it, since it's open at the bottom where the water runs back in the bucket with the pump.

I can take a picture of my setup and post.

OK, since I dropped off the heads and some other item at the machine shop, I started on the transmission.

I know it needs a new synchro ring for 1st gear, bearings, etc.









The first gear synchro need everything, New ring, gear ring and shift sleeve.

In the picture bottom is the new, top the old.



Here are the housing pieces rough cleaned



Comparison.

Before wet blasting


After

That's one heck of any oil change! Love seeing all the parts clean up like that. My wet blast envy grows with every post!

Carmagic, Absolutely gorgeous work, I’m jealous!!

Got some more work done. I will not go in all the details, but here are some pictures from the transmission.

Ready to put it back together,



The backlash of the R&P was off, so I had to play with some shims.



After that was in specs, playing again with shims for the pre-load.

Now adjusting the shift rods.



One more check with the housing in place,



All back apart and now final assembly.



Here it is, ready to go.



Here is the old parts collection.



Next post will be from the Engine.

Happy weekend

OK, I'm trying to catch up my posting with the work I have done.

Here are some pictures of the engine assembly.

Testing and cleaning up the WUR and Aux Air Valve

Before


After


Got all the parts back, so I can start with the assembly of the engine.


The crank shaft bearings are in good condition and micro polished. The rod have new bushings and new bearings.




Ready for the other half to come on.


I like to apply the loctite on the upper half.


Supertec head studs installed.


Pistons and Cylinders are ready for installation.




Next, the heads. The 98mm Cylinders don't use head gaskets


Also the air guides must be installed before the heads.


The cam housings are next.


It already looks like something, LOL.


More to come.

Cheers
Engelbert

More awesomeness!
