I live in the UK and have a Record DML24 wood turning lathe. I would like to
add electronic speed control to this. Does any one know if this is possible? |

Steve it should be possible but you will need to change the Motor to a
3 Phase Motor which while you are doing this you may wish to increase
the Power from the 1/3rd HP upto say a 1/2HP.
I notice that 1/3rd HP Motors come in Frame Size 63 and 71 whereas
1/2HP Motors are generally available as Frame Size 71, this refers to
the height to the centre of the Shaft in mm.
Also Frame 63 Motors have a 11mm Dia. shaft whereas Frame 71 are with a
14mm shaft.
So there are a number of issues to take into consideration.
Any larger and you may also have to think about the Pulley Bore and
Motor Fixing/Mounting.
I did an upgrade on my Hegner and have included the process in the
Hints & Tips Section of my WEB Site.

Possible with DC motors. I know that (at least one) AC motors can be
damaged when connected to speed controls. I have a variable speed,
plus a reseversing switch, on my DC motor--it's great. |

Penn State Industries has just released a variable speed motor kit for delta
and jet mini-lathes. Cost is around $120 US. Might be a better answer. Kit
contains new motor and speed control unit. Here is link..

My lathe varies speed through a 2 pulley system one on the motor shaft
and one one the lathe spindle. As you change the speed one pulley will
open up reducing its diameter as the other pulley will close down
increasing its diameter. There must be a name for this type of system
but I don't know it.
My problem is the slowest speed is still too fast for the bigger
blanks.
Is there a way I can change the speed of the AC motor to compensate
for the high ratio of the pulleys.
Thanks in Advance
Peter
