No need to use a key in the saw. However a key in the plain portion of a collar wil help stop the cutter turning.

Got the key out of the arbor. Ahhh, the taste of sweet success! laugh

Again a big thank you to all for the tips and suggestions and a special shoutout to both Nicholas and Nigel - using the vise to hold the key while oh-so-gently tapping the arbor upwards with a padded hammer did the trick.

Evidently there was a combination of a slightly roughened key along with a wee touch of manufacturing swarf that was preventing me from removing the little sucker. I cleaned out the groove and then very lightly stoned the sides and corners of the key. It now slides in and out of position as it should without any undo play.

Problem solved and I can now mount my slitting saws as hoped for!

As an Apprentice, (at a world renowned maker of engines, cars and gas turbines) we were told NEVER to use a key with a slitting saw. One of my fellows forgot, and the flying bits of a six inch dia saw just missed several of us, the other half was still rotating on the arbor.

If it jams, it slips, but does not become dangerous shrapnel!

I was taught the same when apprenticed at what was Dorman Long, Forty Foot rd. Middlesbrough back in the 60's along with, never wear gloves on any rotating equipment, always grind the mushroom head off the cold chisel ( shouldn't have let it get that far in the first place was my ear bashing ) always measure twice before cutting, along with a myriad of other old stuff that still applies today, & yes I've had many a test piece flung down the length of the fitting shop by the charge hand accompanied by ' what the **** do you call that piece of s***!... do it again!. Aaah the good old days... crying 2 thinking... have also had my ear clipped  by my allocated fitter when I made mistakes, along with the appropriate vernacular.

George.
