That trick is usable on many machines with an open horizontal spindle. I just scored an old Hammond tool and cutter grinder which isn't really designed for mill sharpening, but adding a spindex will be a natural fit. You can clamp a shop vac hose with a wide nozzle aligned with the plane of wheel rotation to catch some of the dust. It's an ancient trick as is putting a panty hose leg over your vacuum filter to prevent clogging.
Hi Shadon, Good deal. Its a fine tradition using a tool for something the designers never thought of. I see you have added a pattern of tapped holes in the bottom of your spin indexer. Is that to mount it to an angle plate? All the best, Tom
+Shadon HKW regrind shops( in my area at least) do reconditioning for fractions of what new tools cost. I am one such. also offering recoating Gordon form tools
Very cool idea Stan, thanks for the tip and especially the warning lol. I had to chuckle cause most of the time I do catch myself before doing something stupid, but not always 😜 Ian Little
To catch the abrasive dust I use "sticky mats" cardboard with grease spread on it. The dust sticks to it and does not bounce or slip off. After the jod they are bagged and binned.
Just found this Shadon. Just got a cheapy spindex - and have various plans for it after truing it up etc and making it better. Interesting approach - 10:4 re the AlO grit! (Or is it AlO2 - forget my valencies!)
I'm not sure I know what you are doing with your "probe". So you're turning the handle on the Spindex and because the "probe" is sitting in the flutes, it pulls the spindle of the spindex forward, aligning the flute edges of the mill with the grinding wheel? Not sure I'd have much luck with my Spindex. whenever I have tried to use it, it chatters. Too much play between the spindle and the casting.even when the locking pin is engaged.
The Clarkson T&CG uses pieces of flat spring steel (re-purposed hacksaw blade) as the tool rests. Because of the spring action, you can use them as a ratchet when indexing the tool. John Stevenson has a channel here and participates on many forums. His wife sells engineering stuff on ebay (marypoppinsbag) and they do a DVD on Tool an Cutter grinding which many have found useful (item 360797299864 just now). I have two complete Clarksons that exist only as a pile of bits awaiting rebuild. A wheel guard would not only be safer, but allow you to capture a good deal of the dust with a vacuum cleaner whilst grinding.
A flat piece of spring steel is brilliant, after using this set up for a few hours, I can see the value it could provide. Ill look into a Clarkson, thanks for the comment.
Mighty expensive bench grinder. I would think your surface grinder would do a nicer job, and i bet you could still rig your rotation probe to work also. Just a thought. Be Careful and Stay Safe Bob
your vise is packed full of abrasive…… will take more than removing sliding J to clean that. and I believe you will have to plow your nut and it’s way through the Alum ox to get it out… maybe get a dedicated vise or just make a riser for spinD?
+brucegor Hey Bruce, I'm sure this method is horrible to watch for a pro, the setup time alone makes this ineffective, let alone the questionable results, I'm still on the prowl for a nice KO Lee or Denkel.
+Shadon HKW . sorry did not mean to disparage what you did.I see a lot of time and effort in that set up.as i said needs must when the devil drives. quick note when useing the centering post do not touch off on the wheel with it runing. instead rock the wheel and feed in till it touches or better yet put a shim between. that saves the post. i make my own for my ko lee radius fixture. ko lee wants an arm and leg for replacement
Now that's gotta be the best idea I've seen for sharping end mill bit's Thanks
I really want to see a lot more of this project!!
Thanks Stan I love the creativity. I was wondering how to do this. Another Bulls Eye for You Tube viewers like me.

Interesting....it would be cool to see the actual grinding in action!

All the best,

Whoops replied before I saw the bracket.
Best,

oxtoolco Still need a tool grinder for the shop, your little Deckel looks handy, any recommendations?

i like the out of the box thinking.
thanks for sharing the great idea!
Hi did you ever do a video on how to sharpen the ends of the end mills
nice job. i like when people get creative with what thay have
A nice and nifty little idea when you have many af these dead endmills and other cutting peaces too, I beleave !
... and we all have !
Excellent idea and video. Thanks.

Hi mate.
Bloody smart cookie you are. I don't know how ridged the set up is, but it's pretty clever.

Great idea I'm stealing it!
That's genius.

let the man turn his milling machine.
I mean how often does it happen ya know
It just occurred to me shell mills could be adapted to this setup for sharpening.

I like it!
regrinding services out here in Ca. will refurbish these endmills for Approx 20% of new price. 7 axis cnc cutter grinders
Hey again Bruce, go ahead and throw up a link, I will make sure it gets pinned to the top, good resharpening services are hard to find.
A.C. drill. Not sure how to do links.
They are in Anaheim ,Ca. They also coat.
great ingenuity
Brilliant
Clever
Nice
"Needs Must" ;)

Genius
whew thats some fred flintstone s--t right there. sorry "needs must" I'm a cutter grinder by trade
