(sound of forehead being slapped) - I hadn't realised it was a link. I must thank your colleagues for the effort they have also put in trying to help me

Is it something I should be able to see on this thread? Like an attachment?

I'm sorry, but for some reason, I received no notification of your last post :( hence the delay Taking your suggestions in order: I had also feared I had damaged the original bearings by over-tightening the roller drive belt, so for each of the subsequent sets of bearings I have fitted, I have...

Thanks yet again for your very quick response - I really appreciate it. Since I've retired, I no longer have access to the sort of EEs that you describe - so I would be grateful if you could re-post this link. Regarding the input wiring issue you describe, are there any benefits in me making...

Thank you. I thought it might be appropriate to dismantle one of the two motors and post some pictures. Nothing looks wrong to my (untrained) eyes. What I find most baffling, is that the noise, to all intents and purposes, is identical from both motors. Both motors initially worked fine...

Guineafowl21 - did the attached mp3 file give you what you requested?

Again, thank you for your suggestions. TheUnicorn - I was able to do a variant of what you had suggested, I couldn't move the motor away, but by unwinding some of the motor power leads from the ferrite ring and providing a new earth connection, I was able move the circuit board away - see...

Thank you all for your suggestions - much appreciated Terry, yes the treadmill does have a controller board - it is shown in the first photo just to the left of the motor. Fitzroy, I'll give this a go a bit later today Ttrees, sooner you than me 🤐 Myfordman, I would like to pursue your...

Thanks Mark - I'm also hoping that it will be OK, but I'll just wait a little longer before doing so :) As I re-read my post I realise I hadn't really described the noise itself. It's not the sort of noise that I would have naturally associated with worn bearings - it is a whine, but no...

Hi, I hope someone can help. I have previously asked for assistance and been very pleased with the help and advice the members have provided. This time I recognise it's a bit cheeky of me to ask the question of this forum, as it isn't exactly workshop related - but it is a motor and / or...

Thanks Chas, for your quick reply. Sadly, I am quite new to a lot of this, so may need a bit more spoon feeding :-| For 1 & 2, is my first step to strip the spindle out of the drill, to enable taking the measurements? For 3 - does this photo help at all - I'm not sure where the slot for the...

I know it will a lot more effort and expense that refurbishing the no1 MT - but I really would like to press on with my late father's goal of upgrading to a no.2 MT. Can someone point me at what I need?

OK, thank you. I found the point on the taper that was 12.065 in diameter - it was just a couple of mm from the back of the chuck. As I have no way of measuring the angle, I measured the diameter close to the other end of the taper (40mm along from the first measurement) it was 10.006mm, so by...

Thanks for that. I have dropped the chuck from the spindle, but am struggling to see where I make the measurements to tie up with the table. Better news, I think I have cracked the file upload issue - I have resized them to below the 256Kb forum threshold

Thanks for the reply Steve. May I ask, what part of my description is pointing you at a Morse Taper as opposed to the Jacobs' taper?
