Yep seconds per hole and all nice and square and if you need to go back you can’t cross threat the tap either.

I’ve been very happy with the taps and will likely look to see what else they make in that department…
@jackdawg4579 21 күн бұрын
So how high did you space the plate above the deck to be sure you wouldnt end up bottoming your tap out on the bench surface? That would be my biggest fear! Also I like the YG taps as well, a mechanical engineer mate put me on to them a few years ago, cheap as chips on ali express.

I am wondering is that a Visby. I just purchased a Russian lathe manufactured in 1976. I have to decode all the different diagramatic plates. I have not used a lathe in a very long time. The Russian lathe is a bit of a beast weighing at approximately 4 tonnes. It came with steadies, 3 and 4 jaw chucks etc etc. Also a large multi drawer cabinet with a treasure trove of cutting tips . Problem is, I have to admit I probably don't know how to use the bloody thing. I will learn as I do have the basic knowledge required. The gear box/headstock must easily weigh well over a metric tonne. I had to sort out the electrics..........managed that and it is humming along. Power feed to the carriage and slides. I'm hoping to pick up some basics from your videos.
@docsofftopic8130 4 ай бұрын
The lathe I do my turning with is a 1937/8 Southbend 9c, the blue mystery project lathe is likely a Hercus made version of a pope 13” swing lathe from around the mid 1920’ though likely made in the 1930’s.
@StuartsShed 5 ай бұрын
I have a very similar mill - VERY similar. With careful use and setup they can be very accurate machine tools. They may not hog out huge cuts of material, but you can make accurate parts with good finishes, as long as you are patient.
@docsofftopic8130 4 ай бұрын
It’s a nice machine for sure, and like all light mills defs not for hogging, but it will get jobs done. I’d like to add dro to the quill and a mm scale on the column bug that’s about all I’d change right now. One day maybe power feed but not right now.

A useful tool - and you got through it and got it done. I need to make a pair - a little something for the weekend I think. Possibly holding the balls with V blocks and using a smaller end mill may have gone better. Thanks for posting the video. 👍

Mount so your cutting force is directed into the fixed jaw… and soft jaws if doing them from hardened steel.

A match pair… Wouldn’t it be better to have a match triplet? You’ll have the 3 points required for a surface. Bore the soft jaw at 1/3 the diameter and chamfer. That has more contact surface than the dimple you make and is less aggressive to the clamp. (Adjust the size of the hole according to the thickness of the material)
@docsofftopic8130 5 ай бұрын
It would have but given the condition of the balls I figured it wasn’t worth the effort. Next time though if I can get some 25-30mm balls that are new I’d defs be up for it.
@01thomasss 5 ай бұрын
Hi I have the same lathe as you, also with the main bearing oilers on top of the bearings and not on the sides as with the later South Bend 9-inchers. My question is: how do you achieve such accurate metric dimensions with a lathe calibrated imperially? With me it's mostly 'hit-&-miss'. Cheers, Thomas
@docsofftopic8130 5 ай бұрын
Three main things to keep in mind; the first is that 1/1000” is 25.4microns, the second is you need to know the backlash in your machine, on mine the cross slide screw is visibly worn and has a hair over 20/1000” backlash, the third is practice. I build my first lathe from scratch and it has no feed dials, so I learnt to go slow and to know how much to expect from a given amount of feed. And as I neared final dimension measured lots.

Hi Have you considered just using spiral flute machine taps? Just grip the tap tightly in the tailstock chuck, select low speed (40rpm) and use the jog button to start. Don't lock the tailstock down. Just slide it into the job and push it until the tap starts. It will automatically pull itself into the work. When the desired depth is reached, just reverse out.
@docsofftopic8130 5 ай бұрын
Would mean duplicating existing tooling some of which very old imperial sizing (pre ww2) so if I don’t have it’s a win. This also works in the mill and drill press.
@johnspathonis1078 5 ай бұрын
I have made the decision not to machine anthing that is not metric unless it absolutely has to. You can use the same technique on a mill or drill press as long as RPM is dialed down. Once you have used spiral flute machine taps you will not use anything else. A good brand is YG1 from South Korea. Cheers @@docsofftopic8130

Keep the ball from moving, depending on geometry they can get squeezed out if left spherical. Second into minimise damage to your vice jaws.

@@docsofftopic8130 I see what you mean about damaging the vise jaws. Did you damage yours too? How would a matched pair work on a rough casting? Did you wreck the insert edges cutting hardened steel? Did you consider holding the ball between two nuts to protect the jaws? Or maybe use one nut and no flat to hold a casting.

When I made them I just took them to the disc sander and flattened a spot in about 2 or 3 minutes. You just need a flat to prevent indentation of your movable vise jaw…..that’s all.

So you simply copied prezzos recent video. The reason for the flat is to prevent dents in the vice jaw which will transfer to future parts. Yet you held the balls against the jaws and putting a dent in them! Use a nut or a washer to sit the ball in, no flat required.
