Is that an ER collet for the post? That will lock it in well if it is.

Yup, it work well so far

Hughie, I couldn't think of a more frustrating device to use than an ER ?? Collet Chuck in that situation. But I guess you have a good reason?

lol I had one,I admit this lathe has not had a lot of use, so its in the trial stages still

Only ever seen the banjo handle at the opposite end to the tool post on dedicated bowl lathes, like...

That works OK when you are standing at the open end of the lathe.

Hughie... am I right in seeing that banjo on a lathe like that?

The collet chucks on the removable handles I have been using seem to hold gouges firmly enough with just an hand twist, although the force applied in use with them is more rotational than axial thrust.

Given the large size of that collet chuck I expect you would be able to apply a fair twist by hand onto the tool post. But, if it needs a handle every time it has to be adjusted then that would be a PITB for me.

I sometimes have an issue with sawdust feeding down the post when adjusting the height with one of my tool rests and I'm thinking that fine sawdust falling down the tool post could perhaps be an issue with the collet mechanism, but in practice that may not be the case.

To date the dust falling hasnt been a problem on my other lathe, although it doesnt have a collet. I had thought it might be an issue, probably go with a soft collar.

I pretty well only do bowls or hollow vessels and I have seen a banjo with tool post at both ends. I did give the various options a lot of thought. The double ended affair I couldnt see any great benefit for me. My banjos are quite long at 300 long as a minimum with the tool-post carrier to the left-hand side of the banjo and always at the end as seen here. This lathe has a longish bed for a bowl lathe so getting around the end wont be so comfortable as my short bed, which is around 700.
