Hi
On my Drummond flat bed lathe I added another arm so I could fit another set of gears to have a slower feed . These are the pin type gears .The lead screw is 8 tpi

HI
How would you check a square .I use a bottle square I ground . as I said before if you have an accurate angle plate that's square on the side as well . with a fence fitted just locate on the fence and its square . also on a surface grinder with a mag chuck lay it on its side with with the job in place switch on clamp job . then switch off stand A. P up and you are ready to go . Bear in mind the angle plate must be dead square on all faces . no square required in this operation . Valid on a mill table as well  Try it it works fine

Hi
It may have been said . After squaring / tramming head clamp a 4" angle plate to the machine table . Place the job vertical against the angle plate resting on a flat parallel say about 1/2" if there is no fence on angle plate square using an accurate Square . clamp using two toolmakers clamps . Face end using face mill or fly cutter . Job done

Hi Frank
I photo may help new members a Wobbler/ edge finder may be confused with a wiggler as in John's post.
They are both useful in the home workshop and at work

Hi Guys
As Bob says .you may wont to check holes for roundness, bell mouthed etc inside calipers are tended to be forgotten in this digital age . I always talk now about the home shop machinist not industry . you can measure deep into the hole you are boring . I have also made some gauges similar to inside micrometers but have to be measured with a micrometer I also have a metric M&W set Nobby

Hi Jack
If I recall it was 6 BA / the pitch is no problem as its just for adjustment. If I was marking out a job against an angle plate on a surface plate as Neil says I'm lucky I have a 10 inch Mitutoyo height gauge

Hi Jack
I added fine adjustment to my digital caliper
Nobby

Hi Jack and Guys
I always make a rule to use a micrometer where possible if I can ....A vernier caliper if in a awkward place A scribing block toolmakers use a lot with a DTI fitted for use with slips / gauge blocks to transfer to the job. No and no go gauges i found useful. For measuring holes. our firm had a DEA machine on a granite surface plate with a probe
For example touch the inside of a hole in 3 or more place.s and read the result . You could also print out the result.

HI Richard & Guy's
I needed a fixed steady for a job on my S7 . So i made a simple one and it works well
Nobby

Hi Rik
Yes I raised my Myford S7 about 4" and it saved me bending over the machine & it saved my back from hurting

Hi
Here we go . On a CNC lathe the finishing cut would only be a few lines position 1 linear move to position 2
Nobby

If you have any items in the workshop with the taper required on. fit on lathe between centre.clock along with top slide until Zero then it is set at that angle .
Nobby

Hi Yngvar
I fitted a mandrel that I screw my drill chuck., cutter holders, fly cutter ect to as you know it has a morse taper 2
Please see photo or my album No morse taper Nobby

Hi Lathejack & Guy
Here is a photo of my Kerry with guard up also showing some cutters on bench

Hi Lathejack
I have a Kerry Super 8 . I have fitted an X Y table & clock for z depth . great for milling with various cutters
I don't mill with cutters in drill chuck.
