John Glands Dalton

Hi All

I had nothing to do this morning so I posted some pictures of John
Glands 1915 B-4 Lot 4 serial number 2270.

For you guys that are looking for a drive for your Dalton take a
look at the last couple of pictures and you will see the one I built
for Johns Lathe. This lathe will fit on a 22 inch wide bench and is
really compact. The frame is just angle iron and to it is bolted a
Atlas vertical countershaft. These are always available on eBay and
I actually have a couple of them here if anyone is interested in
purchasing one for there lathe. As you can see in the photos I used
a poly Vee drive belt. These are available from McMaster Carr for
about $20 bucks and they come in a variety of lengths so you can
match up with your drive. These belts really grip and they like to
squeal before they start to slip. Run very smooth also.

As to the post about a VFD or variable speed drive they will work
just great but remember you will need to us a countershaft of some
kind were you can reduce the speed of the motor by at least 2 to 1
if not 3 to 1. If you try and run direct to the lathe from a VFD
equipped motor you will burn the windings out of your motor at slow
speeds. There is just not enough air moving over the field windings
to keep them cool. VFD's will really pump the power into your
windings at very slow speed trying to keep the torque up and really
heat things up in doing so. If you can not run a reduction on the
motor then you will have to put an additional fan on the motor to
cool it.

With the price of VFD's coming down they are becoming a drive of
chouse for many lathe owners. A 1 hp drive can be gotten off eBay
now for under $100. These give you a lot of flexibility in setting
up a simple drive but remember to set the top speed of the spindle
at 1000 or less or you will be looking for someone to make you a new
set of spindle bearings.

Dennis,
?
Does John Gland's motor and countershaft rely on its weight pivoted back to apply pressure to the belt or is there a fixed arm locking the belt tension in??

Hi Brad
?
Yes there are two little slotted arms you cant see that hold the motor in place but adjustable.
