Thread: What lathe
23/01/2021 12:45:53

Joshua, you have now arrived at the position most of us faced at one time or another, I had a super 7 for years which is now with my son, an excellent quality product but limited in capacity. I went for a Warco 290V lathe, so much more capable than the Myford but rough as old boots in places. Your choice as always is old British/American/European iron or new Chinese products, both have their good & bad points!

If pre loved, condition is key as you have found out so if going down that route again you must see the lathe in the flesh, if you don't like change gears & who does get a screw cutting gearbox.

There are loads of threads on this subject but no easy answers.

Joshua, so at present you have no lathe & are asking advice as to what to buy?

Joshua, It is very likely the Myford lathe had/has an imperial leadscrew, so if you were cutting a metric thread on it you must keep the half nuts engaged at all times, after one pass stop the motor, put the motor into reverse & drive the tool back towards the tail stock to start the next cut.

Thread: How not to use a clamp
22/01/2021 12:30:22

Clamp bar looks level to me so ok to use, what I don't like or do is put the step blocks straight onto my precious ground table, in industry & now at home I use surface ground 6 mm hardened steel plates to spread the clamping load, just a little foible of minewink

Thread: Myford ML7 Chucks - Which one?
22/01/2021 09:37:05

I'm not sure why but all the import chucks seem to be 'long', i,e, more overhang from the spindle bearings.

Thread: Myford spindle rectification or replacement

Yes definitely something showing up on the thread as Diogenes II mentions.

You are not checking the spindle in you videos, you need to check the actual spindle, i.e. the register diameter & the register face. From memory the Super 7 spindle is hardened so very unlikely to be damaged, the thread outside diameter can be checked with a dial gauge using an 'elephants foot' [large diameter] stylus to bridge the threads, you can also check the threads themselves by setting the lathe to cut the same pitch as the spindle thread & use a very small stylus to bear on the thread flanks but maybe tricky for a beginner?

Thread: Vertex (V4?) Rotary Table

Try milling a large 'square' on the RT or Div head & then check to see how square it actually is and are opposite sides parallel?

Thread: Telescopic Bore Gauges
18/01/2021 13:40:09

'This Old Tony' on Youtube did a video on improving a set of telescopic bore gauges, it might be useful having a look to inform your buying decision. I wouldn't personally buy this sort of thing for less than £20, it would end in tears. The Kennedy ones look OK & you can always get a refund if they are a load of rubbish but as they are mainly an industrial supplier you should be alright.

Thread: Vertex (V4?) Rotary Table

Hold on, hold on, what dividing head are you using & what plates have you got? You should be able to get closer than 1 degree over 360 degrees.

Thread: Spur gear help.
15/01/2021 17:17:50

I looked at the 'Rushgears.com' calculator & as Jason says 1.375" centre distance doesn't give a meaningful answer. I'm guessing the mill is a 'Herbert'?

Thread: Identifying Internal threads

Okay not easy with your limited 'equipment',what m/c is it & how do you know it's not metric? Give us the manufacturers name that will be a good clue.

Two more to report here,

ebay numbers 224312889459 and 224312889782

Definitely the same scammer.

The exact Boxford lathe was listed by a guy in Southend Nov 2019.

I think the only choices are a dealer or Ebay if you need to sell as one lot, or maybe Face Book market place.

Apparently it's got a quick change gear box & 26-3000 rpm spindle speed plus a metric threaded nose, 1" headstock bore & 4 MT in the spindle? Some ML7!! Item reported to Ebay.
