Great feedback, thanks. 3-phase would be overkill I think, it's only a 7x14 minilathe. This sewing machine motor's been working well although I still need to finesse the pulley ratios a little.

Thanks for your kind words, Sam! Appreciate you taking the time.

Hery, thanks for commenting. Yes, I did make slots there with tensioning in mind but they're very awkward to get at. The slider arrangement you see in this video is much easier to deal with. Appreciate your input, thanks for dropping by.

Good info, thanks 👍

Great feedback Colin, really appreciate you taking the time. I was tempted to mill it flat myself but wasn't sure what else that might affect, so good to know it's a possibility for the future. Thanks again mate, really useful information and great to hear from you 👍

@@myharris Many thanks for the reply. Looking at my notes it's 7 years since I delved into the back end of the pump and mine, for some reason, has a slightly different arrangement for the regulator. It has an extra spring above the piston so there is a light, long spring down the middle of a shorter stiffer spring. It also has two bypass holes, the lower 1.25mm diameter and the upper of 2.5mm diameter. I had a bit of fun "walking in the footsteps" of the original designers by sticking the spring rates etc. onto a spreadsheet to work out how the pressure would vary with rpm and thought just how much hard work the original guys would have had with slide-rule and log tables to do what a click of a mouse allowed me to calculate. It set me wondering if they did this sort of thing by calculation or experimentation - I guess we will never know for sure.

The motor came with instructions on how to reverse rotation. It's a series of keypresses on the keypad under the readout, I can't remember offhand the exact sequence but I'd assume it'll be specified in the paperwork that comes with the specific motor you get. Thanks for stopping by, appreciate you taking the time.

No quill, but there's a fine-feed wheel which works just as well for close work. Hope this helps, appreciate you stopping by. Best, Harris

You're very welcome Doug, thanks again for taking the time. Best of luck with your rebuild mate, do let me know how you get on. All the best 👍

Cheers Doug, really appreciate you taking the time. It is a bit daunting but I just watched all the videos I could find and pored over the manual. Lance's video included in the description is pretty much definitive. Just take it steady mate, you''ll be good 👍

Thanks bud, much appreciated :)

They were GBP15 each, which is about US$19.

Thanks so much for your kind words David, that's great feedback! Appreciate you taking the time 😁

Brute force and ignorance go a long way in my workshop! 😂 Thanks again, glad you're enjoying the content.

As I say at 09:13, I tightened the c-nuts til it felt free-running but without being free-wheeling. A little later on I check the deflection with a dial indicator which showed about 1/3 of 0.01mm.

Hey Steve, I'm glad you enjoyed the video and many thanks for the feedback. Thanks also for the steer to the other channels, and also for the tip about the Noga deburrer clone - I keep meaning to hunt one downbut the Stanley knife is always on hand!Good luck with the centre plate - it would be great to see the results when you're finished :) Appreciate you taking the time 🙏

Hey Lucian, thanks for your feedback. I use 2 ancient Samsung Galaxy S5s, they really work well - true 4k, removable batteries, and cheap as chips :)

Glad it helped. Incredible how robust these things are. It was still working after 60 years! Appreciate your feedback, thanks 👍

A fair question I'd say. It's straight through, no taper at all. I wish it was MT2! Appreciate your input, thanks for taking the time 👍

You're most welcome, glad to have helped. How did the job go? Thanks for your input 👍

Hey John, thanks for stopping by and for your kind words. That's an interesting idea, I hadn't got as far as thinking about that. Ebay here I come! Appreciate your input, thanks again

Hey Jim, thanks for dropping by. Do you mean the electrical enclosure box on the Sieg SX2P mini mill in the background? If so, check out the video here: ua-cam.com/video/BQQUafty1lI/v-deo.html - it's not a bad video, if I say so myself, plus there are download links there for the box's STL file. As to payment - just click the 'like' button and leave extravagantly flattering comments on all my videos. Deal?! 😂 Appreciate your comment buddy, all the best.

Not that one the one that houses the stepper controller and the transformer, don’t know the actual size but thinking it might fit the boxes in my country.

@@Bigbigjimbo Sorry, I'm being a bit slow today! Are we talking about the lathe or the mill? The controller box for the lathe is metal and came with the machine. The mill transformer and controller box likewise. Dial me in a bit! Happy to send some measurements if that would help?

@@myharris my mistake it is not you that is adding the electronic lead screw, i watch that may of these things lol

Hi Richard, thanks for taking the time. It's a great question and one I should've addressed in the video. Space is really limited behind the lathe, and it's a proper pita to get to the 4 motor mounting bolts. Trying to get the belt tension right whilst keeping the motor in alignment under those conditions ends up being a multi-hour curse-fest! I wanted something that was easier to get to, and more capable of delivering consistent results. Appreciate your feedback, and great to see someone's giving my little videos such close attention! All the best. 👍

I'm past the point of being annoyed by this stuff - well, almost past the point! These days I just assume I'm getting a semi-finished self-assembly kit from the get-go. Ya get what you pay for - and ya pay for what ya get! Thanks for taking the time Robert, appreciate your input 👍

Hey Shawn, really appreciate your kind words, and also your long-time loyalty. Your machining videos are definitely worth watching, and I'd recommend anyone reading this to swing by your channel for insights. Thanks again for your support buddy, it really means a lot 🙏

Really appreciate your feedback Glenn, a major part of the motivation for these videos is the support and generosity of spirit I've found in our mutual community of like-minded hobby machinists. I'm finding your videos a solidly useful source of mini lathe mods and tips and would recommend anyone reading this comment to check out your channel. Very best of luck with your belt-tensioner project - hope my screw-ups supply some lessons!!

I did consider this but it's much easier to grip and align a square-section toolbit shaft than a circular one. Which isn't to say that it's impossible! However, I happened to have the length of 8mm HSS bar stock you see in the video and decided to go with that. Appreciate your input, thanks for taking the time 👍

Not quite with you - flask? How do you mean? Appreciate your input, many thanks

Maybe he meant chuck end bearing cover

This is the one I got: www.ebay.co.uk/itm/125617202047

Thanks Glenn, really appreciate your support.

Now that's a great tip for future reference! Never occurred to me. Appreciate that Peter, many thanks.

Yes, we're West Midlands - rolling green hills and some lovely twisty roads. The bike's been sitting under a cover in the barn for a while now sadly, I just haven't had the time. She needs a new timing chain, which I have on the shelf but balers and tractors are currently taking priority!

Thanks Bill! Necessity being the mother of invention and all that 😁
