Both good points. A LH thread would have cost the factory nothing. An adjustment system might have added a penny or two, but at least they could have provided say 4 to 6 positions for the handle.
In any case I have found no disadvantage with having a rear mount, I have used the rear mount for over 10 years.

this is a good idea for some, buit for me outa sight outa mind....I would still leave it tight. I just added a nice stiff spring inbetween so they were held apart. witch pretty much keep the arm up when you unlock it. and down is locked. I did that years ago....but i still check every time I use the machine.old habbets seem to be hard to break. my quill has some good marks on it from somebody not paying attn.... before I got the refurbusshed machine... I dont know who/what company refer bushed it, but i think they just had a joint in 1 hand and a spray can in the other hand....smoking their referbush and spray painting the mill. you cant fix stupid, ugly can be fixed, stupid ..not!!! good thing I didnt pay a lot for it...( it's fine, but not reworked like it should of been,or that I was led to be leave)
