Love the factory cabinet base. Believe Van Dorn was eventually acquired by Black and Decker. Do you have the jig to chamfer the ends of the valve stems?

It sure does look similar to a Black&Decker one I had twenty five years ago.

Does it have a coolant pump or is it set for dry grinding?

I'm using an old Sioux 680 that I have had for many years.
I have also had several of the old B&D units as well as an older Sioux as well.

Just used it a few weeks ago to build a couple sets of heads

That bent drawer front is just damn cool....

And I approve of the ambient music. I like to think that VanDorn would, also!

Hang onto that beauty. It's got another hundred years of life left, easy.

I have an ancient seat grinding tool, which would go nicely with that.
A while back I saw a tool for setting the angles and truing up the grinding wheels, but it took me too long to figure out what it was for and I did not buy it. I regret that now.

Here are a couple pics of a Black & Decker version of the valve grinder, probably several years newer than your Van Dorn. Like others have said I sure do like that cabinet base you have for yours. This one has a coolant reservoir and pump and came with a ton of tooling. Ed.

Ahhhh... the good old days. When Black and Decker made quality tools instead of cheap junk.

oooh, another valve grinder thread!

here's mine. I don't have the diamond point for truing the wheels but so far it had done dozens of small engine valves and one V6 Taurus...when I first got it it was missing the collet (I thought) and I almost scrapped it. then I started cleaning it and found the collet sitting in the oil pump drawer.

wish I had the vinyl cover like the photo!!!

I bought this one a couple of years ago for about 40$ on an auction here in Sweden. The owner of a local tractor workshop retired so he sold most of his stuff:


Was a machine under the dirt


I changed the long leather "wire" and got it to work, but a valve will not center correctly, so Im looking for a new collet. I have found a couple from other models, but they are expensive, so I have not bought any yet as I dont know it they fit. I would also like to buy some extra stones too if I find a collet.

Not sure what you paid, but a decent one on racingjunk runs $500~1000 or better.

Cool machine.. Do you know how to dress the grinding wheel? It looks like it needs it. Its usually done with a diamond tipped dressing tool that somehow chucks up so you get the angle you need on the wheel itself. If you don't do that and run the machine dry (doesn't appear to have wet grinding capability), you stand the chance of grinder burning the valve..

I haven't ground valves on a machine like that since high school auto shop..

I bought a 680 a few years ago. Came with a compressed-air-powered seat grinder, a few pilots, a few stones, two very ratty stone holders, some seat cutters, the cabinet, two stone-dressers but only one had the diamond-point, the fixture for butt-grinding the valve stem, and some miscellaneous crap. Did not come with the fixture for refacing rocker arms.

I had to re-mount the motor for the chuck; clean...everything. Twice. Apparently, the previous owners NEVER cleaned this machine. I made other minor repairs. The valve-holding chuck needed to be re-set on it's threads; it can be assembled four ways and three of them are wrong. I've played with the carriage ways, and the backlash on the handwheel adjustment. And then I cleaned it again.

I bought more pilots, more stones, a concentricity gauge, and a really crappy photocopy of the owner's manual from a guy on eBay that sells a lot of photocopied owner's manuals for various machinery.

At this point, it will hold 0.0005 runout pretty consistently; sometimes better. At the time, I thought the price was very ordinary, even a little high. I bought it because there just wasn't anything else available, and I had a cylinder head project. Wasn't until later I discovered that $650 was a screaming bargain, all things considered.

Fantastic machine, even if there are newer models. I might want the variable-speed chuck from one of the newer machines--but for automotive work I don't really need it. The only thing that it genuinely lacks is the ability to accept modern small-diameter valve stems; although I think I can finesse 5.5 mm stems, there's just no hope of anything smaller fitting the chuck.

Kool, I spent a lot of time on a Sioux valve grinder. I think I retaught every young tech we got how to grind valves.

Good spot.. sort of looks like it.. but the way its set up it certainly wasn't a full flow setup.. Seems like the one we had in high school was full blown coolant flow with a catch tray underneath everything.....

At one point had considered it, and then engine work went away. My Bud had a Bud who saved one from a dumpster and it got passed to me for free and somewhere we scored seat tools in the deal. I did a dry grind on 1 valve the other day, just a touch.
We use it once in a while, if I was farting with old engines all the time would certainly consider today to hunt down a bargain sale set.
Allow for fix it now no cost repair. I can do golf carts ad the recent repair was a minor grind to 1 valve, didn't do anything to the rest of it but clean.
I use it so occasionally actually have a cox its covered with and put on a shelf out of the way with the forklift, its great to have,,, out of the way.
The seat stuff is used, a lot of stones though and I been able to make it. The grinder was NIB, sat in a half busted packing crate taking space in my Buds place and finally to me where I was the first one ever used it.
