Today I acquired...........

[The_Yellow_Ardvark]

After a week of hotels, many miles and some goos customers. This what I aquired this week.

Part One.

A Oil can and a wire brush.

The painfull end of a 50 Call.

That money again, two decks of cards and a Old style razor.

A old and odd tin.

A old vice.

A bit of rust.

 

[The_Yellow_Ardvark]

Part 2.

More money.

A set of number punches. I have not seen them yet, as the box is still sealed after all these years.

A old style foot measure, to work out what size shoes you need.

All skip finds.

 

[The_Yellow_Ardvark]

This lot was in a skip in a loading bay of a shopping centre, I am guessing it was pulled from a second hand shop that had closed. I never went it after the first time.
They had items that were over priced, rude staff and not much else.

Both still have the wax sealing intact on them. They rattle so I am guessing they are full.

In good order.

Just need to find a box now.

This was the item I was realy after, the rest was just in the way.

Dunno if it's Griffin, or Griffin & George, I remember. Their balances were ubiquitous in our school when I was growing up, and I'm sure they supplied loads of the chemistry department's reagents (reagent! ).

I have to ask @The_Yellow_Ardvark what do you do with all your ‘stuff’?

Define stuff.

 

[Easywelder]

All the interesting things you acquire on a daily basis

All the interesting things you acquire on a daily basis

Oh that stuff.
Restore it, use it and make use of it.
Some goes to MIS, some I sell, some I donnate to good life forms.

 

[Tigman]

Haven't seen thrupenny bits for a long time !

 

[Tigman]

Oh I was referring to the coins !

 

[tigdlo]

This is going to have to earn its keep

Have you cut anything yet?

 

[angellonewolf]

I donnate to good life forms

as long as there not hammers for @Parm

 

[Parm]

as long as there not hammers for @Parm

Hang on a minute, let’s not go there

I’m currently due a hammer and an axe !

 

[awemawson]

Haven't seen thrupenny bits for a long time !

I have two bags of thrupenny bits in uncirculated condition if anybody lusts after them. I took then out of the bank when they announced their withdrawal in 1971 and still have them.

... some parts for the Myfords, after a loooong way to me.

I am extraordinarily grateful to a fellow forumist helpful beyond measure for his patience, perseverance and collegiality in the face of the greatest adversity.

Thank you



First, a 3D printed tool acquired via eBay.co.uk for fixing the bullgear on Myfords when changing jaw chucks without losing teeth on the backgear.

This part is of really remarkably poor fit ... but see for yourself:

Top tip: Don't bye it!


I've been desperate to get this for a while, I finally saw the advantages of using it for parting off while relieving the front spindle bearing, let's see how it does, it's an original:

Included was this parting knife holder with a remnant parting knife.
The screws are recognizably dead, certainly not there from the beginning and with their drive also completely unsuitable to apply the necessary force to clamp the knife securely.

Fortunately, the three broken screws were sent with it and I unpacked my full set of thread gauges.
Since the parts came from British lands, I started with BSW, then UNF, UNC and even "4 to 42 V-Thread" - nothing wanted to match right and the damaged threads have not made it easy.

At some point I was fed up and took from my small screw stock any somehow suitable looking screw and tried .... fit on the first try - for whatever reason,
but it is quite a normal M3x0.5mm thread in the knife holder and I have several dozen of them.

Finally also these three Allen screws in the right length in stainless .... fixed!

A little cleaning and care would do any of the items good .... comes.


Been wanting one for a while, especially since I learned here how important a supported workpiece can be for good results:

After a while ago a fellow forumist already gave me a fixed steady rest, now I have an additional traveling steady in quasi-new condition.

I have also wanted this one for a while:

Whether it will allow me to disengage in between when cutting metric threads - which should not be possible they say
- I will now find out, but it is a helpful extension in any case.

This part also needs attention, but after a few drops of oil, it already works without complaint.


I wish everyone a wonderful weekend and thank you again to my brave helper!


Best regards


Carsten

I think I'm right with this :-
The counter will simply turn as the shaft rotates so it will be a few trials of seeing where the graduations line up . If it's no good for metric perhaps make a slip over magnetic cap with one marked point for metric if they aren't accurate enough & run in from a fixed carriage stop block so you know where the thread starts

Pay you dues, then visit.
I will supply them to you. Plus a coffee.


Failing that I keep them.

I will soon. You knew my predicament

I don't think that's right. A thread dial indicator only works with metric threads using a metric lead screw or imperial threads with imperial leadscrew. All the TDI does is keep track of the linear position of the saddle wrt the lead screw orientation. It is permanently locked to the lead screw so that when it rotates one full turn, the saddle has moved a known distance (typically one inch on an imperial lathe).

You can frig an imperial lathe to move in mm by using 254/10 steps (or a 127 tooth gear wheel etc) but the lead screw is a fixed number of turns of the TDI per inch. So far as I can tell, once you lose the relationship between the position of the gearbox and the orientation of the lead screw, the toolpath no longer tracks the thread pitch.

My guess is if you had a similar 254/127 ratio in the TDI then it might allow you to pick up the half nut where you left off. However you would then have to move the saddle an unfeasible distance and pick up the correct 254/127 "mark" before it fell back in phase...

Bit of a head scratcher to be honest but simply changing the dial face on the TDI won't help (I don't think).

I can cut metric & imperial on my antique Atlas using the same thread dial indicator & lead screw , nothing changes save for the change gears . I suspect Carsten will have change gears for metric thread cutting on his Myford lathe .

see :- https://www.model-engineer.co.uk/news/article/metric-myford-threads/27223

Such gears 3D printed if not readily available appear to be good for many lathes , as they are somewhat strong There might be some on such sites as thingyverse etc just ther for th paying a small fee and getting thm printed .

I can get a full set plus extra's for the Atlas , but if I wanted I think I could 3D draw and print individuals in ABS without much difficulty . Apparently a lot of modern home hobby lathes are using plastic gears as well as a few industrial ones.
