The Secret Society of Lathe Trolls

Wow. I thought the speed changes would be very slight and difficult to discern but no. There's really quite a difference in speeds.

"I think it is possible to press such a small cone into aluminum just by pressure." That is an interesting idea. You could through drill 1.2mm, make a press tool out of 1.5mm carbide rod (with a blunt end at say... just under 1.2mm) and tap the tapered rod in and then press it back out from the othe...

Hi All! I'm building a similar overhead for a friend and he suggested looking at VinylBurn for controlling it. Just reading through the thread, the photo interrupters seem to be causing some people grief. If all we're trying to do is get a 1 or 0 out of a physical sensor, why not use a Hall effect s...

Long way from that as yet.

I remade the funnel cutting jog from nylon bar and the result is good.

The funnels as cut are well matched weight wise



and they are not all marked up like the earlier ones I made using the aluminium funnel holding jig.

Hi All, When I was building the half scale VMS I realised that I would need a cutting head. I was impressed with the KNOP head and I bought two bodies (one pla & one resin) and all the other necessary parts. Only later did I realise that the KNOP head would be too big for the half scale VMS. In my d...

Mack Stevens approached me to make him 10 new tungsten carbide cutting styli. IMG_0036.JPG 1.5mm x 19mm (1/16" x 3/4") I have 8 left over from the batch of 20 I made. Some are "super-finished" and some normal. The "super-finished" styli have just the very tips polished using a 1200 grit wheel. I hav...

Regarding ball screws, I considered "upgrading" the half scale VMS 70 to ball screws but abandoned it as an idea due to concerns over noise. The VMS 70 saddle actually does run on ball bearings (which I did not know when I made the half scale model). If I had known, I suspect I still would not have ...

Yes, retaining the housing and magnet is a sound idea.

I look forward to seeing more of your posts on this project.

Hi Thomas, I was looking at your cutter head. Its very professionally done but I wonder if you shouldn't just bite the bullet and go 100% home made by winding your own coils. While tweeters may be convenient I can't help but think they are not ideal and given the splendid effort you have already mad...

Hi All, As with all things, it takes longer than you think it will. If I had some money I could speed up the next part of the project (mostly electrical / electronic parts). Would anyone be interested in making their own half scale VMS or making it from parts? I'm considering selling new parts based...

Very very cool!!!

Thanks!

Your project is considerably cooler though....

My friend Louie made himself a cabinet....



You open it and all the records come out in a sliding rack.

Or that's the idea! That feature is yet to be implanted but.... damn.... I love that cabinet he made.

Wilson. Cheers,

I used to make needles with a jig but you're limited to one geometry. Now that I got used to using the tool & cutter grinder for making embossing cones I thought I'd use it for needles too.

Hmmm... its working for me but maybe I can see the images because I'm hosting them on my own site.

I'll try it again but with attachments.

Well done! That is a novel solution to a difficult problem. Model engineers have the same problem reaming small tapered holes and what they do is to make a " D Bit Reamer ". https://www.homemodelenginemachinist.com/threads/making-a-tapered-d-bit.23861/ It's usually done on a lathe but there seems no...

Hi All, I made an air spindle for my grinder to make super accurate embossing cones. https://www.youtube.com/watch?v=v9LnN5laF0Y I don't have a working record lathe. Would anyone like to test one of these for me ? Your choice of cone angle (its 87 degrees in the video). Postage costs only (I am in t...

Is the plug "special" ?

I've had a lot of experience finding (and sadly making) weird plugs.

Can you post a picture of it?

Thanks for the comments guys. It's made of brass. Bored 16mm, lapped & polished, cross drilled with two rows of four, 4 thou holes, about a half inch from each end. The compressor is a very old Binks Bullows : https://www.ebay.co.uk/itm/265197028203?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&tool...

Hi All, I recently made an air spindle for another purpose (tool & cutter grinder) but I hear that they were used in record lathes. Now that I've made one I could fit it to my Neumann VMS70 project but aren't they a massive source of white noise? https://www.youtube.com/watch?v=otwqjbgnxqw Cheers, W...
