I'm sure you could build one.
The last one I had was made from parts cut from a propane tank and lined with 1/2 inch thick rubber conveyor belt. It was mounted on 4 large valve springs. When I got it the crank assembly had broken away from the bottom of the tank. After re-enforcing that the bearings the crank was turning in proved to be to light for the job. [A norton crank and a couple superblends would probably work nice]
The price for media is shocking... Jim

My unit is a little over 3 cu ft. You need to have a few inches clearance around the parts and the tub dimensions vary.
The media is a mixture of Microbrite porcelain balls of 3 and 4 mm and two other things that I really don't know.
I sent two cracked heads to a media supply outfit and they sent them back with different finishes for me to choose from.
They supplied the media with a custom mix number so I could buy more -from them. They were actually very helpful. Jim

Hey Jim and All
I run several vibratubs at my machine shop. Media can vary in cost. There are only a handful of companies that make the media, the cost depends on which distributor you use, and the quantity (in pounds) that you buy. We use vibratory process for several finishing issues. We use it for primary deburring (especially for blanked parts that are then going on to gearing) We also use the process for prepping for anodizing, and for final polish. We use these processes for steel, aluminum and other non-ferrous materials.
Would love to compare notes with you on these processes

John,
I have a small tub also that is the same model as yours. I have been using it for deburring for several years. I run it with either plastic or ceramic media. [aluminum or steel] It will not fit a head or cases however. Jim
And your right about the media prices. Generally anywhere from $5.00 a lb to $25.00 a lb by the time it's delivered in the quantities I use.

Do ya have room and change left for a N2 gas powered cyrogenic 'puter controlled tempering box? Easiest way to remove valve seats and densify and destress head at same time. Might not even have to heat cases to drop in a super chilled bearings but don't drop to shatter. Ammo reloaders love their case polishing units.

... I had my engine tumbled using this kind of UFO shaped steel media...

We use the "flying saucer" type media (made of stainless, and it cost an arm and leg) to polish stainless parts. Works quite well
How much does your machine hold?
I'm sure this is not the right size, but $15 a pound might be worth a shot.
