Also those holders for the inserts are not shouldered so all the force goes on the lower section, whereas with your setup you have the full depth of the blade.don't know what you mean,
thats 60mm diameter EN3 bar on my hobbymat, which isnt the most sturdy of lathes
The rear toolpost is something I haven't tried or have. But I can visulise the benefits. The extra rigidity comes from it being mounted directly on the cross-slide, so that also does away with the toolpost side overhang. The tool is downwards cutting, which will assist swarf removal, unless you run lathe in reverse, which is unwise on a RH screwed on chuck. The action will try to lift the rear of the saddle which is pretty tight with the gib strip. On my Colchester there is significant lift in the front of the saddle, but the locking clamp, which stops sideways movement also stops that. However the action is still a downwards force and still equates to lifting the rear of saddle.Thanks all. All i've ever used are the hss type parting tools on proper lathes. My myford came with a hss parting tool, but I haven't used it. I'm upgrading the tool post to a gib type which I got from banggood.
Why is it recommended to use the parting tool on a rear tool post?
I'm not sure of what the motor is rated at, but i'll probably run a 2mm gtn insert. I imagine that it would have an easier time dealing with a 2mm cut.
Thanks to whoever mentioned arceuro. I was struggling to find somewhere other than china to order from for a reasonable price. Looks like I can get the whole lot together instead of having to order everything separately as well.
