Stent Tool Grinder

[Howard LewisParticipant @howardlewis46836]

Holding square or rectangular pieces in the Worden is easy. I was thinking more in terms of being able to hold square workpieces in a collet for turning, to minimise the work needed to set it to run concentric.

So this is the wrong place to have that particular discusion.

Fair enough, Howard. I wasn't having a go at you or anyone else. Too late to edit my post, so please ignore it.

No offence taken, John.

Just that I am very prone to taking threads off topic!

Actually, collets are far less used in the lathe than chucks. Collets are far more often used for work holding or trying to sharpen drills.

See? He's at it again!

If you know someone with an EDM machine it would be easy to make an ER collet to suit !

Not a daft question. Why do you want one?
if you go onto the Bristol model engineers site they do a very simple cutter grinder that I made and sold recently as I can no longer work. It was featured in MEW no 47 and called the Collier Caseley. No castings needed,made from stock materials, driven by 1/8 hp motor and diamond cup wheel. 2, 3 and4 flute cutters can be sharpened ON THE END only – never had the need to do the sides.
I have pics but cannot get then onto this site but can email if you contact off line.

As mentioned by Pete above. two more pictures in my album. If you have half a brain you can see how it works and make the equivalent out of whatever you have to hand. The tool is swung across the wheel similarly to a Quorn.

[Mark RandParticipant @markrand96270]

To be fair, I trawled the BSME site and couldn't find peter's grinder.

Many thanks John

Holding a tap in a round collet has the safety factor that if anything jams, or gets too tight, it slips, reducingb then risk of a broken tap.
