Thread: Problems with Mardrive
10/03/2023 10:30:31

Hi Noel, Thanks for the wiring instructions. I feel a bit uncomfortable about the asbestos in the switch as it looks very tatty so I have contacted Santon switchgear Ltd and they have an identical modern equivalant switch with the same code number accept with an added P ie SRP 137KA instead of the old SR 137KA. They have advised me that the switch is the equivalent so I'm wondering about getting it. I am already getting the clutch thrust brake pad replaced at the moment at a surprisingly resonable cost so will feel more comfortable using the lathe again. From your very knowlegable advice you've given me would I be correct to go down this route. Many thanks Martin

Thank you Noel, I shall attempt your instructions but might ask a ''sparks' neighbour for help. Just out of interest are there equivalent replavcements for these old switches? Martin

img_8556.jpgimg_8555.jpgimg_8554.jpgimg_8552.jpgHi Noel Images of the switch which is indeed a Santon. Also a reversing on off switch I had to put on my Myford when the main control switch gave up. Could something like this be a replac ement? Thanks Martinimg_8551.jpeg

internal.jpeginternal.jpegGetting a bit paranoid now as I was looking at the guts of the forward /reverse switch on the pultra cabinet and noticed the wired parts I have circled in red. Are these also Asbestos? as they look pretty ragged. If they are should I look for a replacement modorn switch equivalent? appreciate your advice Martinfront of switch.jpg

Hi Noel, Yes sorry about that. I would like to be able to reverse the motor and also have some wiring diagrams. I would be very grateful for those. Thanks Martin.

Hi, I have a Pultra Lathe that has been in storage for some time. I am now trying to assemble it to use in a new workshop. I have put the machine together but have found a part left over that I can't see would fit anywhere. (image attached) pultra 2.jpg I discovered from the wealth of original literature that came with the lathe that it is a clutch thrust and spring. Secondly Whilst the lathe was in store my carefully labelled wiring decription ( image att) pultra.jpgto the front control switch has faded and I don't know what goes where. Would anyone be able to in simple 'leyman's terms' advise me on this problem. Lastly while searching for the odd left over part above in the literature I worryingly discovered that the brake pad on the Mardrive pulley system supposidly has an Asbestos brake pad. (image att 13B))pultra 3.jpgHas anyone come up against this problem and could advise how to replace or resolve this predicament. Many thanks.

Thanks to you all.

Sorry having problems with adding the image but have done it now I think. Martin.

img_1285.jpgFour years ago I dismantled my Pultra lathe whilst moving workshops. Only now have I been able to re-assemble the unit but I have come up against problems due to my stupidity ant not noting down where certain parts came from. I have attached an image of a part that I assumed came from inside the clutch cone of the motor but if it is put there the clutch cone cane be returned to its original position. I am hoping in anticipation that someone has had experience of Mardrive units and could advise. Many thanks.

Thread: Wiring problems
29/06/2011 11:09:54
Recently moved premises and dismantled myford super seven for move but on rewiring motor according to my sketched wiring diagram and attempting to turn on the lathe just throws the trip switch on the main power board. I haven't changed anything I think so don't understand the problem. I have attached images of the on off switch which I haven't touched and the inside of the motor. The only wires I have attached are earth/brown to U1/blue to U2 and two black wires to S terminal (one of which I have removed prior to the taking the image) all others are as they were. Can anyone help please. Thank you
