There is a dirty great bolt through the handwheel that holds the chuck in. It would get interesting turning without it.

It might look spindly but I have not noticed any bouncing. It is bolted to the floor and the bed rails are filled with concrete.

Now that you have said that I am going to be paranoid about every little vibration.

What I did to outboard turn was (2) things. I had a large alo gluechuck made up (120mm) with a left hand thread.
If I am using the supa nova chuck, I use a L Hand adaptor. I have found these two ways successful. I have found using
hot melt glue with the alo chuck very successful and to date I have not had any problems with this approach in
turning large bowls or platters (up to 400mm). I am about to go bigger with a large platter of monteray pine.
As you know, I am sure, keep the speed down, until you get it into balance and then in safe increments. I do not turn in reverse,
but some do, where they have ample room on both sides of the lathe. Drillit.
PS. I limit reverse to sanding.

Alo?

Nice range of speeds on the lathe. Did you fill the bed tubes with concrete, or did they come that way from the factory?

I have a Hegner with square steel tubes for the bed which shakes like a dog pooping peach seeds, and rings like a bell. I have considered drilling out the ends and filling the tubes with machine setting grout. Maybe even running a 5/8 inch rebar down the middle to stiffen things.

Yours looks like a nice stout lathe. What is the swing over the bed?

Hi Paul,

The lathe came from the factory with the concrete in the tubes. The tubes are welded to 5 mm steel plate at the ends and I think the tubes are 4 or 5 mm wall thickness. I was told the concrete was to dampen vibration.

It will swing 50 cm (20 inches) over the bed and 80 cm (32 inches) outboard. The biggest piece I have had on it was about 40 cm (16 inches). It's not too bad as long as you keep the speed down until things are in balance.

Thanks Michael,

I tried to find more information on the lathe. I found two that were offered for sale in NZ, one with a photo on a rather spindly stand.
