I am wanting to build a decent bench grinder tool rest for grinding lathe tools. I can grind free hand quite well but I want something better. The tool rests that came with the grinder I have are adjustable forward and backward only. I want to build a tool rest that will adjust for height, vertically and for angular tilt. I have plans for the Tinker as well as the Mini Tinker, but I want something simpler. I have a Quorn Tool and Cutter Grinder about 80% finished so I don't need a real elaborate system for the bench grinder. Are there any ideas out there that I could use to replace the stock tool rests?

Dick,
I don't have an answer for you. However, I look forward to watching as others respond.
Should you ever decide to drive toward Dayton. Please send me a PM I give you an address and you can stop for coffee!

what ever you do , design it so if something does get stuck, the table falls away from the wheel and not jam into it so the wheel explodes and ruins your day

How about the Glendo grinder tool rest?

I have one of these in front of my bench grinder and it works okay. The grit tends to get into the adjustment part of the rest but it is solid enough. Pricey, though. Maybe take a look and fab up something similar?

I like the "Advanced Grinding Rest" that Harold Hall describes in his book "Milling, A Complete Course". You can see pictures of it at
http://www.homews.co.uk/page398.html
(By the way don't blame Mr. Hall for that title. It was probably a publisher's decision. "Milling, A Project Based Course for Beginners" would probably have been a better title. I highly recommend the book to beginners.

If you search Amazon for "Harold Hall metal" you will find two similar books. "Milling, A Complete Course" in the Workshop Practice series (published in the UK) and "Milling for Home Machinists" published by Fox Chapel (USA). According to Mr. Hall the books are almost identical with just a few editorial changes to translate from British english to American english. No attempt was made to change the drawings from metric to imperial units.

Of course a search on youtube will bring up a whole list of other grinding tables.

Probably similar to the grinding rest in "milling for home machinists" by Harold Hall. Personally, I found his book difficult to follow, as he would repeatedly use machining-specific terms without defining them, and go back and forth between the part drawings and pictures of the parts themselves to figure out what he wanted done on the part. And there was a number of "just do this, I'll explain later". And I've taken drafting classes as well as civil and mechanical engineering courses in University.

Had to see what a Quorn Tool grinder is, Google turned up a picture quickly.

If you already have the skills to build such a tool why are you asking questions here?

I bought the tool rest from Veritas and love it. It's not heavy duty but at least is all metal except the adjusting handle. For grinding lathe tooling it's been fine for me for the couple of years I've had mine. I bought two of them since I hadn't had the time...or desire honestly..to build one.

I am just looking for suggestions. There may be an idea out here somewhere that I never considered. I also realize I don't know everything and never will. When we work alone in at a hobby like ours it is easy to develop tunnel vision and not be able to see the forest for the trees. We are all part of a larger community and I enjoy the camaraderie here.

I kinda like the advanced grinder rest that Harold Hall designed and built. Something like this could could be put together rather quickly using cold rolled 1018. My bench grinder could be mounted on a heavy board and have a T track inset into the board out in front of the grinder. That way I could slide the rest assembly from wheel to wheel or quickly remove it when desired . I have a 36 grit on one end and a 60 grit on the other end. Thanks for the idea.

Hi Dick,

@Splat beat me to it regarding the Lee Valley/Veritas grinding rest.

I got one with a little grinder I bought used. It has worked very well for me. One great feature is that that the adjusting handles can be pulled out and set at any angle to get them out of the way.
I was thinking about another one, but the price is kinda steep.....I should build one.

It comes as just the rest:

or as a kit with a chisel and plane blade grinding jig:

I might mention that Veritas tends to make too many things out of aluminum. Even with anodizing,it might not bee long before the tool resting table gets coated with annoying pieces of embedded grit,scratching up everything you rest on it.

I think the simple,bent heavy gauge sheet steel TWO PIECE tool rests on my old 1963 Craftsman 6" grinder do everything I need to do. The Craftsman tool rests are "double jointed",and can be configured into many different positions. They are made of steel,and in all these years,there is not a single embedded speck of grit in them.

Far too often these days,bench grinders have only single piece tool rests,or a tool rest that only allows you to rest a tool that is facing STRAIGHT INTO the grinding wheel. I think a lot of these tool rests are designed by someone who has NO EXPERIENCE in grinding tools.

My Harbor freight bench grinder has awful tool rests. I get the tool close then take it to my big Jet 12" disc sander/ grinder with right media. Precision is way easier no facets. Before my jet I had some cheesy little 6 inch disc but was still better than the grinder for the big finish.

Some day I'll get this project done, I got it cheep ,it's well made , but can't seem to find much info about it. It's adjustable to just about any angle ,not shop made but should grind lathe tools good
The wheels could be hard to find and expensive tho

The tool holder slides on a 1.5" round shaft and has a bearing that rides on the bar
Although it does take up some valuable floor space
