Fluid for Sioux valve surfacer

Bruce, I can already picture myself using this to turn all kinds of stuff, like one of those repair type head studs with 1/2" threads into the block and ground to 7/16" above. This thing's a Mad Scientist's dream.
Here's some pics showing the nozzles and pump etc. I see nothing complex about running a dry sump and a coolant tank. Heck, I even have an old remote mount spin on oil filter assembly and a 12 v fuel pump. Like I have nothing better to do....

Just looked at the pictures of your valve grinder. You will be happy to know that if you ever need to grind valves with mushroom stems, the chuck you have allows for that without a lot of difficulty. It's a very time consuming thing to grind them with a quick release chuck. Just another plus for you.

Thanks for the heads up! I have always used the later style valves in the past, but I have a bucketfull of the early ones. I would also like to build an engine with the factory solid lifters. The way this machine is set up I can see it isn't rocket science grinding the stems. I have done some testing on various adjustable lifters and even new they vary greatly in their resistence to turning. I posted a thread on this 'scientific' testing procedure titled 'Light in the Lifters', or maybe 'Loose in the lifters'.....
 
KOOL machine, & very useful. My engine business buddy gave me one like it. We were converting "A" engines to main bearing inserts, he did all the machine work & hated to assemble them. So he paid me a great wage to assemble them, including going to straight Chevy valve trains. Went on for a few years then he passed away & was out of a job (hobby).
This was all 30 years ago & I had no use for the valve grinding machine anymore so gave it away- someone got REAL lucky!

Use soluble oil and water , it cools better and doesn't carry the abrasive through the pump like oil does . I have the same machine as you, got it in 1962
I've ground a lot of valves since then.

I have these Sioux valve grinding machines. The old Model 620 is a dry grinder that I used a lot until I got the Model 645 wet grinder.Both have the capability to grind the valve stems. I need to change the coolant so where do I get the water soluble oil ? And how much. ?

lathes ,mills, broach cutters and wet grinders have always used soluble oil mix but use what ever the manufacturer says its their machine and wheels
 
This is right up there with a good old fashioned 'what motor oil' thread. Do they make synthetic grinding fluid?
