Ooops... Hit the wrong button!

For some time I've been thinking of adding a full size milling spindle to my Taylor Hobson CX engraving machine.

I was going to make my own spindle but yesterday I rediscovered a rusty Myford Lathe bed with headstock in the deep dark recesses of my garden shed.

A few hours work & the headstock appears viable - bearingd & tapet socket protectef by old oil - 😁result 😁

Another few hours & a simple bracket show that it will fit & in the lashed up shown gives a useable surface area of 6" x 18" ish with up to 6" depth.

Does the panel think that it's a viable project?

As a professional horologist...... I would fix it with a new one.

There is a reason why good old fashioned machines/engineers use fine threads. 😁

With watchmaking it's only when you stop losing things that you start to get anywhere 😁

I'm sorry it's sideways (my phone is insisting that it be so!)

What does the hive mind think about my Super compound slide?

The indexing handle works as normal, albeit with horrendous backlash & not as smoothly as I'd like. When pushed forwards the small lever at the back advances the slide by precisely 1/8th of an inch & vice versa.

Knowing something of the history of my mistress I think that I know it's precise use but I'd like to hear your unpredudiced ideas before offering my own.

Hi Pete,

I'm a little late getting to this thread but have read your exploits with interest.

We could almost be twins!

I'm a 1959 vintage Burtonian with a recently installed Super 7 (1962 model so it's just younger than me) I'm also a recent heart attack survivor , April 28th 2018 & used my Covid furlough to bring initiate my retirement project early.

If your lathe is still in need of some turning mine has offered it's services 😊

Get back to me here or PM if we can be of any help or if you just want to meet up for a beer & compare notes about our mechanical mistresses 🍻

Cheers..... Ady@Burton

It's always nice to find out something new .....

As my old dad used to say

'A day without learning is as disappointing as a day without beer' 🍻 😁

Yippppeeee I've found my answer 😊

As I suspected the tool colour relates to the grade of carbide & what material it is designed to cut.

Generally speaking :-

Blue is for steel

Yellow for Stainless Steel

Red for Cast Iron

Green for Non Ferrous

Khaki / Brown for Heat resistant alloy - Titanium Alloy

&

Silver / Grey for Hardend steel

It's 1AM & now I can finally go to sleep & rest easy

😁😴😴😴😴

Hi Bazyle,

I'm not so sure that colours are a whim. Some of the pictures of sets that I've seen do have descriptions of the tools :8 of one, 6 of another, ect. & the quantaties do seem to match up with photos.

You are correct about the wheel engine it does look like a modified chronos, can model engineers ever resist a modification?

G'day Paul 😁

They are indeed more than a bit heavy for my intended use, it's just that I have got them & would like to know what the colours mean - knowledge is power after all!

Hi Brian,

Thanks for the welcome.

I'm pretty sure it's not just the toolmakers whim because I can find pictures of complete sets that carry the same colours, just can't find out what the colours mean & I'm ever curious about things,

Yep!

It's for synchronising the striking.

Hiyas,

Very young 60+ professional horologist here.

Covid19 furlough has enabled me to complete my retirement project some 10 years early & I now have a shiny new workshop 😊

I aquired the contents of an ex model enginees workshop some 18 years ago & it had been languishing in my front room ever since!

Whilst the main building is completed I'm still sorting out my bits & have yet to commission my equipment - 1962 Myford super 7 with attachments, clock wheel cutting engine, pillar drill, sensitive drill with tapping jig, lever press, grinding wheel, polishing motor & various other bits & bobs.

Anyways ..... Sorting through my toys I've come a cross several part sets of brazed carbide lathe tools painted in various colours - red, green, yellow, blue, silver/grey - Now I'm sure that the colours mean something but, for the life of me I can't discover what!

I'm pretty sure that it's a novice question but could somebody please put me out of my misery?

Thanks in advance

Ady@Burton
