I got a Titan Lathe ( TL180V )secondhand just before Christmas. I've tried a few things with it but find it quite a finicky beast. It is nothing like the old Colchesters I remember from school days. My first issue is with just how speed sensitive it is. There seems to be no consistency between cutters even from the same set. The replaceable tip set seems to require higher speeds on brass than on alloy of the same diameter, just not logical.
Specific issues - Anticipated speeds causes bad ribbing on brass, fine manual feed or auto feed. The only way to get anything like a cut is to run flat out. I am able to smooth this out with a Tubalcain shearing cutter copy in tool steel but a 4 inch length of brass supported with live centre has full length concavity. Cutting 9.5mm stock down to 8mm gives 8.12 live centre end, 8.07 at chuck end and 7.92 centre. I could understand if the middle bowed out due to flex in the stock bar.
Is it my tools? see image- cheap chinese supply, came used with the Lathe. I can't afford better. Is there something else going on? Thanks
