Universal Grinding Fixture From Plans

Here are the plans by Doug Ross:
http://www.homemadetools.net/forum/u...9360#post89149

I wanted to make one a bit smaller so I used 2.5" diameter steel for the rotors.
Most of the other parts were made to fit this diameter.
Hot rolled steel was on hand so I used that for the rotors and cold rolled for the flat parts.

Very nice set of complete plans from Doug.
I did not put any numbers on the graduations yet and may do that after I make a stamping fixture.

The divisions are a little cramped with only a 2.5" diameter but are very readable. I think this is just
the ticket for sharpening and forming lathe tool bits.

You did a great job JR, very well executed and displayed, these fixtures will greatly improve the grinding of your lathes tool geometry, I use mine frequently, it comes in very handy especially when grinding say a 29° acme threading tool or a 60° HSS threading tool.

Thanks for posting your completed tool on homemadetools, you can receive any one of my other plans free !

Thanks Again and nice work
Doug

Thanks Doug. The plans are very clear and complete with drawings and dimensions for everything which makes for an easy build.
I have been looking at your extended point center and just may order it in the future.

Thanks again John

Nice! If you post a tool that you made from plans you bought on this site, we'll buy you a free set of plans of your choice. Let me know which ones you want and I'll send them out to you.

Nice job! I like your use of an annular cutter instead of a monster drill bit. And noticed you nearly maxed out you steady rest diameter there. It all worked out perfectly.

JR
Very nice job and I like your altering. Just goes to show nothing is written in stone.
Beautiful job, well documented.
Nelson

Thanks guys, actually I did max out my steady rest! The steel rod I was turning would not fit and I had
to take a file to part of the casting. But it all worked fine in the end. Fun project and I like the results.
Ready to start grinding!

Cheers, JR

Thanks JR, glad you found the Universal Grinding Fixture plans complete and understandable, the Extended Point Live Center really comes in handy for smaller diameter work and trying to incorporate the cutting tools,

Thanks Again
Doug

:thumbsup: Very, Very Nice JR and love the way your scaled it to your needs. The gradations are a thing of beauty also and the finishes superb considering the materials! Thanks for sharing the build and can't wait to see your stamping jig.

Thanks PJ and Doug. I had so much fun making this fixture.
Really, not kidding at all. This was the project where my lathe motor gave up the smoke
and the best thing about that is now my little lathe has a real motor!

Cheers, JR

Thanks PJ

Long time to complete this tool but I had a few things to do first, such as fix my lathe!
So here are the results with the graduations labeled. There are four quadrants on each of
the 3 dials. Don't need anything more than about 20 degrees for the tools I will be grinding.

Obvious zero numerals were not stamped as they are assumed.

Numbers were stamped using a version of Rossbotics Universal Grinding Fixture.

I will post the version that I made shortly.

Turned out great Jr. glad I inspired you to take on a task like this, great work

Doug

Thanks Doug, this fixture is a real aid for grinding lathe tools and keeping the angles
correct. One of these days I might be able to hand grind them but not yet.
The fixture is excellent for taking an unground bit and forming it. Once it is
formed and needs re-grinding I can do that by hand.

Thanks again for the plans,
Cheers, JR
