I know it's not very old, but it does seem to be made in the U.S.A. I've found a few pictures of an older version of the same model, but nothing about manufacturing dates. I figure someone here might be able to tell me a little more based on the UL sticker and such.



Thanks.

i'm not sure of the age, but be careful with that bad boy it will tear your arm off. can you post more pictures of that entire awesome grinder?

i have a 1/3 HP Dayton and a beast that is 3/4 both are 3600 RPM. your slower RPM will give you a lot of the choices that you don't have with the 3600 and with the 1 HP all the power you should need. and it's single phase 2.

just guessing buy i'd say 1970's

Call tech support at Grainger, they should be able to tell you based on the serial number.

I'd estimate 70's vintage as well. If it's got a Made in USA Dayton motor, then it's a USA made machine.

A 1HP 1800 RPM grinder....that's a big grinder! A Baldor equal would probably run you $1000.

Dayton used to be exclusive to Grainger.....correct?

Dayton is a Grainger-owned brand. Just like Speedaire is a Grainger-owned brand.

That model 1Z853 grinder wasn't made by Dayton though, it's just branded Dayton. It was made by Doerr Electric Corp., which was also a Grainger-owned company at the time that grinder was made. Doerr Electric Corp. was established by the sons of Emil Doerr, who was one of the founding partners of Baldor Electric Co. in 1920.

1Z853 is listed in the 1972 Grainger wholesale net price motorbook no. 332 (what they called their catalog back then). Suggested retail price $240.45, Grainger net price $144.25, shipping weight 85 LBS.

It is still listed in the catalog but listed as discontinued. This tells me that it was still available recently (last few years, probably) but the suggestion above about the serial number is probably the only way to find out for sure.

I assume you were looking at the online catalog:

http://www.grainger.com/product/DAYTON-Grinder-1Z853?searchQuery=1Z853

It's not listed in the catalog number index in the No. 401 catalog (2010-11), which is the most recent Grainger (printed) catalog I've got, so it's been gone for at least that long, and I'd guess even somewhat longer than that.

The image in the 1972 catalog is a dead-ringer for what can be seen of it in the OP's photo, and based on the style of the nameplate, I'd bet his is from around that time.

I appreciate the help. I'm more curious than anything. I've found pictures of the same model that are newer, and have the made in Taiwan sticker. I've also found one pic of the same model that had an id plate similar to some of the older Dayton grinders on vintage machinery.

Thanks for the info WWIIjeep. Depending on whether or not your catalog is color or not may help. As I've been researching I've also found other Dayton models with what appears to be the same id plate except the bottom section of the tag is red also.
Here's a better pic of mine.

here's my smaller Dayton grinders for your thread to show the tag being all red instead of red/black. i think both of mine are from the 60's and 70's, but not sure.

by the way your 1 HP Dayton grinder looks awesome.

I believe I have the same as the OP, it's a 10" model and yeah talk about power! I replaced the bearings in mine (6205 btw) and fixed the centrifugal (sp) switch, one of the tabs wouldn't make contact so I soldered a metal disc on one of the pads. Works perfect, quiet and spins forever!

According to mr google, 244 in 1972 dollars is equivalent to 1388 in 2014 dollars, my $40 was well spent!

Drivesitfar, those are nice grinders. I didn't really need a ten inch grinder last year when I found this one. It was just in better shape than the rough block grinder I went to look at. Of course, more is sometimes better. It's my first grinder, and I couldn't be happier with it.

I should clarify about the red and black tag. The other tags I'm referring to that had a red bottom section were the same shape with the same layout as mine. They also still had a black center section. They were divided by the unpainted lines that run all the way across horizontally. So red on top, black in the middle, and more red on bottom.

Dayton seems to have had a variety of shapes and color schemes on their name plates over the years. I don't know if they were era specific, if they overlapped, or certain models got certain plate designs.

$40 is a "you ****" price. I paid $225, which I feel may have been a little high, what with missing a tool rest and eye shields. It just ran so nice, and did take forever to spin down. Of course, besides what are on it in the picture I also got an unused 60 grit wheel, an unused fine wire wheel, and 4 or 5 black and decker buffing wheels (which I probably won't use on the grinder). All of which made me feel better about the price, and I will eventually get around to making the parts it's missing.

$225 for that is a damn good price, especially given its excellent condition. You paid what someone would have in 1972 for it!

Thanks for the pic. Your grinder was definitely made for Dayton/Grainger by Doerr. Grainger owned Doerr from 1969 to 1986, then sold it to Emerson. Doerr made grinders for a lot of other brands, including Dayton/Grainger and Rockwell/Delta.

Here's a Rockwell parts diagram for their 10" grinder made by Doerr, showing some details that can be seen to be exactly the same as yours, especially the tool rests, water pot, base, and the wheel guards and end covers.

A better guess at the age of your grinder, using the same model Doerr made for Rockwell as a guide is 1966 to 1972. After 1972, they changed the style of the base and the water pot, but most of the rest of the grinder remained the same for several more years.

Grainger customer service may or may not be able to give you a better date range. On their older products, especially ones that are 40+ years old, it sometimes depends on who you get on the phone, or who is reading emails that day.

Grainger was no help, but all of you have been. Thank you.

Well if I look at it like that I guess it's not a bad buy. The seller started at $325, but he didn't want to carry it with him when he moved. It was his grandfathers though, and he didn't know a thing about it.

The extras I got with it are pictured below, all on the trunk his grandfather kept the grinder in. I've often alleviated my feelings of overpaying with the fact that these were part of the deal. Of course, I could sell the trunk for a little and recoup some of the cost. However, now I'm feeling better about the price, and I like the trunk.

If you are ever feeling bad about the deal ask some of the guys how much they are paying for the wheels and all the parts to fix their $50 grinders that are half the grinder you own.

you did more than ok because that one sir is a keeper to hand down to your grandson or nephew.

thanks for sharing and if you want to trade my 2 smaller grinders for your one with the extras just say the word and you can keep the trunk.:bounce:

You did great at 225, I would have done the same. Only reason mine was $40 was that guy thought the windings were bad, and local place charges 495 to rewind.
