Duffy's 1/71 Series 1 240z build

I will look into the driveline stuff more. 

 

Diff is prepped for powder coating. Inside is clean and empty. I sealed it to minimize sand and powder getting in. I will then burn the powder off the aluminum parts and then wire wheel smooth and vapor blast to look perfect.

Is this normal practice or your own idea?  Seems messy.  You could probably just rub your greasy hands over the areas you don't want the powder to stick and it would peel off.

Powder can't go some places and it sucks to remove.  The more time I spend prepping the better.  The surface has to have zero grease or it ruins the powder coating.  This is just a easy method to make sure it comes out nice.  They do the same thing with engine blocks.

That was my point.  Ruin the bonding surface if you don't want a bond.  Just some thoughts.  There are other ways too.

Powder coating masking is the worse, it's this terrible rigid tape.  It works, but not nearly as well as this.  If you can sacrifice something to do a firm mask off, it will turn out awesome.  

 

This is just my experience in years of powder coating car parts. I am sure there are other ways.  My powder shop charges me a lot less if I do the prep/ masking.

Well results are awesome. I couldn’t be happier. 

All mating surfaces are free of powder and ready to be put back together

Starting to take the trans apart. Curious if I can getting bearings on and off without a press.

Here is a good source for new r180 shims.

They have all the sizes.

5 speed is mostly apart. Really all I needed was a long puller.

I got the 5 speed close ratio transmission case vapor blasted. Took forever, like most of a day.  Looks good though

We tried that case in the bead blasting cabinet but gave up because it was so slow. We blasted it with the pressure pot instead
