Does anyone use ultrasonic cleaners for their projects? If so, what brand and size would you recommend?
Our local vintage BMW guru, Joe Groeger, has an ultrasonic tank that is just big enough to swallow a /2 engine case. It has to be the easiest way to clean out 60 years of baked on sludge, just dunk the case in for a day with the heater turned up to 200F and some cleaner. Depending on the cleaner you use, it can take some of the shine off a newly bead blasted casting, so test it out first.
These machines are great .....but very expensive . I have combed the web to find something big enough for a block, these will run around $5,000.00-$7,000.00 This is in Canada prices are higher here. Branson is a good brand. http://www.crystalelectronics.ca/
You can submerge the item partially and clean then flip it ....repeat. Seems the vibration is sound and has a science behind it.
This one is affordable and has been working well for me.
It's big enough to accept a 64/32/xx Bing carburetor body.
