Baz,

Several ;points arise.
The first was a 'plastic' Vernier which I found in my late wife's orthodontic tool kit. It probably had been sterilised too many times and is rock solid.

As for a tail turret, I have yet to sort out a 6 station one that probably fits the saddle. One of those round tuits! However there is a Ken Metcalf one that he fitted to a Myford ML7. Maybe you have it in your download.

However, Sparey made drawings for his and that appears in his Amateurs Lathe book. Otherwise, Myford DID make a capstan attachment to fit on a ML7 lathe bed. I came across it whilst doing a sort out- probably when the turret affair finally materialised.

Does this help, please. I am in the midst( mist?) of sorting tax and estate problems but drop me an e-mail and I'll try to find something amongst my stuff.

Off hand, I think that JohnB has raised this matter too.

Regards

Norman

As a sort of addendum, I have traced TWO Myford ones from a French site. Unfortunately, I think that they are too poor to copy but both are really for collets which is where you came in.

There is the Cleeve one which was rack operated but I'll have to rack( ouch) to find the French site all this stuff was printed.

Default tooling wall bracket

Thank you Blogwitch for pointing me towards a better system.Likr the more compact setup but didn't like the pins.You know me always looking to further improve.I cut 20 no pieces of 25x3 alum angle and filed a small chamfer to obtain a nice sling fit .Screwed to a piece of timber and then to the wall
Works a treatClick image for larger version

Default Carriage travel handwheel

For those reading my threads will know I am currently making a capstan/turret
I have reached a certain stage and wanted to drop back to this thread so I was
familiar with what is required to return to normal.Simple,just remove the leadscrew bracket (2 screws) and wind/slide off the capstan I 1 or 2 assys
Slide back on the main carriage ,refit the leadscrew brkt and tailstock and good to go.Next mod was the carriage handwheel.The 80mm dia plastic one had split next to the grubscrew and was wobbly.My new 100mm cast iron one had arrived so proceeded to fit as photos show.Looks much better and silky smooth.When I used the lathe to make thumbscrews the 16mm keyless chuck was way too big so I ordered a new 10mm one.I machined 12mm off the quill feed screw,cut of the tang from the chuck and gained an extra 40mm
Photos tell the tale.Dont know whats next for lathe mods but will fluctuate between this thread and the capstan/turret modClick image for larger version

Default Threading Dial

I plan to do some single point threading on this lathe.2 no er16 collet chucks
for the turret,and from my memories long long ago whats threading without
trying to hit line with a dial.Bought one awhile ago local off ebay only $25
Decided to fit it,and although its standard for the 7" mini lathe its not just bolt on.had to drill and tap the apron 2 posns for fixings and mill a rebate to
clear the gibb screws.This one has some design changes,i noted the addition
of 2 ball races for the carriage drive.No big deal, anyway works great and fun

Default Mnor mods

I have mentioned on my other thread that the only thing stopping the
capstan assy winding straight off the lathe was the top part of the leadscrew
brkt and it was no problem.I decided it was simple to fix,i milled off the top section of the brkt and drilled/tapped for a secondary fixing.Now the capstan
winds off without removing the brkt and the tailstock drops on.
The power cable came out of the rear of the back cover and with my limited
space was in danger of damage so I bored a new conduit hole and took the lead out of the top.Much better.I have also started single point screw cutting
with this lathe which I will post on the capstan thread.Looking good so far
The thread indicator works well but instead of trying to catch a line,i approach the work using the carriage handwheel and the lathe off,engage the leadscrew in the correct position and start the lathe.I an only cutting 6 or 7 threads in length,the slow speed bogs down and the lowest I can use is just a bit too fast
so I am reverting to the safe method and turning the chuck by hand.I have cut under powerbut still not confident enough to do everything by the book

I have just spent over half a day screwcutting 2 collet chucks M22x1.5
Had some fun changing the plastic gears,they don't come off easily
Then proceeded screwcutting.Got much easier as I got more familiar
Got down to the last 3 thou on the second one when the carriage started playing up.I had not done the final bedding in on the gibs and they were
slopping about.Reoved the chuck and job and decided to strip down the lathe
Knew I would have to at some time.Could not get a decent adjustment due
to problems with the bed.The tailstock and headsock ends were about 3 thou
bigger than the middle.With the lathe totally stripped I spent a couple of hours with a 4" angle grinder,files emery paper etc to remove the excess from the underside of the ways.Got it down to about a thou then reset the gibs
Much improved so put it all back together and finished the last few thou
on the threading.Satisfying but very frustrating.I should have finished everything off the first time.Screwcutting very successful and the thread dial
made it much easier

Default Rear tool post

I made the rear parting off tool post.Started with a 65mm length of 50mm MSt
Tenoned the underside to fit the T slot with a single M8 fixing.Ready for overall
video now before I strip down and start tidying loose ends ,add some bling etc
and start using it.I have in my head ideas for a tapping head and a self
release die box to fit the turrets.Will post what I do as I do it etc
I have shot a video and will post it on the capstan thread

A possibly stupid question, how do you work out what height to cut the slot for the cut off tool? Is it just the height of the centre of the lathe, then 5mm or 4mm above and below the centre line?

I simply measured the tool and cut to suit lathe centre height
With this parting off tool,the top of the blabe was level with the
top face of the clamping flange.A parting off tool needs to be dead on centre height.I sometimes mount the blade at 5o to produce top rake and avoid having to grind top rake.In this case it was level so any grinding of the tool will
change the height and I will have to pack.Easy enough to do
