If there is no provision for changing the feed direction via the feed
gearbox then I would expect it to be possible to add an idler into the
geartrain driving the feed gearbox. This would reverse the direction. I
am not about to download the 47mb PDF file from harborfreight even with
broadband to find out.

I have a small lathe, similar to this one at Harbor Freight (

Anyway, I would like to be able to machine LH threads but this machine
does not have a reversible leadscrew.

I'm wondering if any of you creative gentlemen may have engineered a
fix for this?

Your help will be appreciated.
