Re: wanted ...armstong/williams holders for my Hendey 14" lathe
+1 on George's suggestion of an Aloris Type toolholder.
by all means get a lantern type toolpost and holders and try working with them.
they did the job for more than 100 years.
OR
you can produce superior work with more rigidity by putting a modern toolpost.
i was a purest as well, on my Atlas TH42 10" lathe.
i, not knowing any better, thought the lantern toolpost just looked cool.
i found myself turning metal alright until it came time to part work off
that's when you will find the true meaning of aggravation.
parting requires rigid set ups and lantern's don't offer the same stiffness.
after fouling a few jobs,i figured out that with my time loss + fouling of work + having to redo work + breaking of parting tooling= the need for a better way
i bought an import version from Shars of the Aloris AXA 100 piston type. cost me about $100 shipped
it was the single best thing i ever did for that lathe. it cut my parting issues dramatically.
Atlas lathes are not the most rigid animals out there, but, the issues that were not solved by the use of the qctp were due to the lathe's limitations and my disregard for those limitations.
i have some williams toolholders laying around, i'd be happy to get them to you.
