Lathe Height
« on: September 06, 2017, 11:55:35 AM »
Hey guys. I'm debating building some stilts for my lathe stands to bring up the center height. The old back gets a bit sore after hunching over for extended periods.

What's the ideal center height? I'm 5'8" (173cm) so I would say about average height. Why does it seem that all import lathes are too short? This is my second lathe, and it's the same center height +/- as my first Craftex lathe.

Thanks for any input.

Hi Paul, I think the recommendation is that the centre height is the distance from the floor to your elbow, with your lower arm held horizontally across your stomach.
I raised my Boxford approximately 4" and I find it's perfect. I'm about the same height as you.

Hi Paul -- I grew up with the same advice as Graham gave you, but in my later life (now 63) I have raised my spindles by 4 inches to make micrometers and dial indicators more readable to my (now) bespectacled eyes.

Have you considered using a high stool?

Works for me at 186cm tall and with a dodgy back.

Thanks chaps - I have to pinch myself and calculate these days to check how old I am - certainly don't feel 68 until something needs doing down at ground level, then reality sinks in  :lol:

Agree with everyone else, get the twirly bits at or above elbow height.  I'm 5'9" and my mini lathe spindle centreline is at 4'2".  I'm an arthritic 70, as of last Monday..............

The elbow height check was originally given for setting the height of vice jaws. This is so the hacksaw cuts nicely at 90 to the work piece (set flush'ish with top of jaws).

A long long time ago when I first set up my ML7 I set the top of the compound slide to "elbow" height.

I am 6' tall and have my spindle at just over 4' and I still find myself stooping over it. I would like it another 3" higher.

Yup,
     Elbow height is good but I'm coming to the conclusion as I begin my 77th orbit of the sun that Elbow plus a hand might be better.
      As Lew said the closer the better for spectacle wearers (Within reason else the loupe might be needed).
     Andrew M , I find that floor level stuff really becomes a problem when trying to get back up. Gravity really works against me then.

Blimey a collection of "SAGA LOUTS", who'd have guessed.  :jaw: :proj: :jaw: :jaw:

Wishing you all many more years to pass on your collective wisdom to us all ,😇

Ps I built all. My lathe workbenches to give me centre height just above elbow level, but fotgot to allow for the thickness of the worktop on the wood lathe( oops 🤢) but on the bright side that makes planing cuts with a skew chisel much easier to do !

Since this has been hijacked once already...
High!  You want the lowest handwheel at elbow height.  And buy a rubber mat to stand on!

I'd love to have my lathe a bit higher - at 6'4" in my underpants, a few hours at the lathe is a recipe for a sore back...

However, having once managed to lift it an inch, an effort which took the best part of an afternoon and copious amounts of sweat, I need to find a better way than a 5ft pry bar!
Cheers!

Elevating my Boxford lathe so the center of apron handwheel matches my elbow height is ideal for me. I'm 6' tall.

The elbow height comes from old visdom when you need power like filing. Think of vice, clamp iron and start filing.




https://ergo-plus.com/fundamental-ergonomic-principles/

There is a difference when arms are used to manipulate something on confortable height. Think of drawing board.

It is actually beneficial to have to move a little on not too essential controls (as long as you don't need to hunch over something dangerous or reach too far to trip) ocassionally. In modern offices peope have way more restricted mobility on "mouse hand" than non-rodent-hand.

Long winded story...where I am getting at?

When lifting: Hands should be in "Power zone" when reaching or lifting or using heavy controls. This is standing position. This ofcourse has a little consideration if the parts you machine are very light weigh and your milling machine has no 1930 lever operated clutch.

When working (sitting or standing): the hands should lie comfortably on the most used controls. And E-stop (button, stomp bar) should be easy to operate.

I see some people hunching over a small lathe like vultures over carcass, that can't be too comfortable. Clock makers lathe table is diferent than floor mounted affair.

Habits are hard to break...I mounted one lathe to "perfect" height. I made the table. 15 years later it is time to come clean and make a new table for it ....it is too low, I can comfortably hunch over it. The thing was - it was perfect height for my vision, now I need glasses (and often magnifying lense), I would like to have it "closer".

The stop start button on the clubs Colchester Master is just above knee height , as I was screw cutting a metric thread on a imperial lathe , stop reverse stop forward repeat until done this got old very quickly especially as you cant see the buttons .

My Bridgeport's e-stop button is at almost exactly knee height. I soon learned to stand well away from the control box whilst milling...
