--- Quote ---John S: Why won't it do LH ? --- End quote --- I was thinking that its only lateral support near the business end was on one side (the face of the fixed part), which will be fine for RH threading. But on LH threads, it will tend to be pushed to the left (from the operator's viewpoint), where the side support is from the nut and washer, a long way from the tooltip and perhaps thus subject to undue leverage. Or have I missed something (I expect I have!). Perhaps there's a tenon hidden beneath. Andy |

Excellent project Darren and I can see one of those lying in the scrap box just waiting to be discovered. :coffee: |
| Darren:
Nice to see it worked for you John and to see they needn't be anything complicated. Does your lathe reverse without stopping ? What is it? |
| John Stevenson:
Darren, It's a TOS 14" swing x 40 BC and is fitted with forward and reverse clutches with a brake in neutral. You can bang it straight from forward to reverse with no problems which makes it ideal for this type of threading. It's made to leave the 1/2 nuts enganged as reverse is 1 1/3 times faster than forward to save time going back, nice machine. Did a LH thread tonight, same pitch, 2mm again no problems in fact it even easier as you are running away from the chuck. Video here:- Finished thread. John S. |

Well I think that demonstrates it rather well, seemed to be no pulling there on the left handers :clap: Thanks for taking the time to do the vid :thumbup: |
