On a recent trip to the UK, I purchased a Glanze parting tool from Chronos Engineering. I experimented with it briefly before using it for a project on a piece of 30mm diameter EN1A. Due to inexperience and/or general mis-handling, I managed to break the insert! I've sent off for a couple of replacements, which should arrive in a few days. While I'm waiting, can anyone answer this question: How do I go about replacing the tip? I tried reversing the broken one, but it was damaged in such a way that it wouldn't (or wasn't meant to) go in that way round. Any tips (pun intended)?

You can't reverse the tip, it only fits one way.
There are no clamps or screws holding the tip in place it just slots into the holder but remains loose until it cuts for the first time. The pressure applied to the tip when it cuts forces the tip into the holder keeping it in place.

Tap the new tip with a bit of brass bar or similar, I lost one forever just relying on the cutting to force it in.

I'm with Gordon on this one. I tap replacements in with the hide mallet just to make sure they are located before use.

I chipped one tapping it with a piece of brass. I'd recommend a hide mallet or better still, push hard against a hardwood object.

I,v just got hold of oneat the local second hand shop for $NZ 2, and a bag of a dozen tips for $NZ1 including a tip that fits the parting tool blade, I think it may be a little bigger than the average modlers size, the tip cuts a 4 mm groove. I,v taken to giving it a whack with the back end of the wire scratch brush. The tip had been used and, it was a bit blunt, but a touch up with a diamond lap, it sailed through a bit of 1" scrap, but because of the width it did pull the revs down a bit (1 1/2 hp). Ian S C

Thanks for all the replies. I think I'll take a good look at the new tips with a magnifying glass when they arrive and dig out the soft mallet. With the cost of airmail postage what it is, this could working out quite an expensive exercise. That'll teach me to be more careful and double-check everything before switching on!

Small ash mallet allows you to safely tap the inerts home with low risk. Mahogony is good too and you don't need a lot to make a tapping mallet!

Thanks. I've found an old woodworking mallet in the bowels of the tool chest which I think will be receiving the attentions of a saw this afternoon then I can use it on the mill drawbar, too, instead of a hammer handle.
