Son of a Harley

My new [to me] shop equipment showed up today.

Now all I need is another couple cubic ft. of porcelain beads and I will be back to shaking heads and cases. Jim

Very nice. Way more efficient that doing it by hand. I had a friend (and Norton rider) in Texas who built his own vibratory cleaner, large enough to easily take crankcases and such. Really made them look nice. I've lusted after one, but don't know where I could fit it in the shop. Too much crap in there already. Soda blasting works pretty well for me, but it's time consuming, messy, and doesn't give as nice a finish.

Can we see something thats been done, when you have given it a tryout.

These vapour blasters (plastic beads in high pressure water) give a pretty nice finish to alloy.
Bit rusty on the steel and iron parts though....

Yeah, I had a homebrew job some years back. It did a great job when it wasn't broken. The bowl finally gave up and it went to the scrap yard. This one seems to be very well built so it should last a long time. Jim

I tried a vapor blaster for a bit. It was very time consuming and didn't give the finish I wanted. The vibratory mill works well to close the porosity in the aluminum and makes them easy to clean.
Depending on the media you use you can do anything from completely stock and new looking to a mirror polish. Jim

Exactly like that. [cylinder head]

Closing the pores . . . . that's the trick.

Snorton74 · Jan 28, 2015

Jim's right about this process really tightening up the porosity. You can really see it around the carb manifold and inlet rocker.

When you stand within about 20 feet of it when it is running, the ground trembles...

I had a guy tumble polish the SU carb bodies from my MG. It would take hours to polish them and that's not the finish I wanted anyway. The nice all-over luster is just perfect.

It makes plenty of noise as is -considering it only has a 2 horsepower motor.
