… aside from making you feel fortunate.

It may be worth looking at this thread from another forum: **LINK**

I was curious as to what this might be so:-


Likewise … and particularly intrigued by this little ‘teaser’ …

Besides detailed drawings, machining instructions and how-to-use info, several ‘extras’ are included, like how to make a lathe sub-faceplate that thinks it’s a magnetic chuck. The "power supply" costs about $2, and it works on ferrous and non-ferrous materials alike - this info alone could be worth the whole price of the drawings!

[sorry about the font change … I just copied and pasted]

The missing teeth were, I believe, an improvement introduced after the original build

I do have some information about the modification, but cannot locate it at present. blush

[…] Then taking a mass 1 kg on a rod 1m long […]



What makes you think that the rod of the conical pendulum is 1m long question

PTFE washers are available

Nicely put, John yes

In my opinion … The Bond was a work of genius

The conical pendulum, in the dome atop, is not the timekeeper as such

… I suppose it best qualifies as something more like a flywheel.



It’s worth watching this :

Thread: Blacking aluminium

Be wary of ‘unsophisticated’ black anodising … it tends to fade to purple with prolonged exposure to light, and also on contact with soluble cutting oil. crying 2

Obviously, these characteristics will vary with the specific materials.

Thread: Moving v belts on pulleys ?
19/06/2022 12:59:06

Loosen the belt laugh

Seriously … if you can’t do that, you are either using the wrong size belt or a very badly designed machine.


Thread: Replacing a 24V AC machine lamp
19/06/2022 08:25:44

Too late to edit, but this is the style of pin clamping/connecting used on my big LOMO microscope:





19/06/2022 06:40:34


I think the underlying problem that you have is the inadequate quality of contact in that type of holder.

The lamp pins oxidise because of the heat generated by contact resistance

A much better arrangement [commonly used in microscope illuminators] is to clamp the pins down on a vee groove; but, of course, you may not have space to do this.



P.S. __ digressing somewhat: This article may be of general interest

Thread: Understanding chuck test certificates
18/06/2022 13:03:51
Posted by DiogenesII on 18/06/2022 07:12:32:

..well, the ticket clearly has spaces below the 'Body No.' serial box for the recording of 'LV' & 'SV' Jaw Set serial numbers - what else might they refer to other than the sets of external & internal jaws supplied with the chuck?


Not sure if that “… well” was intended for me

… but, if so, it completely misses my point.

Hopper’s explanation seems eminently logical to me yes

My only slight misgiving is that I would find it difficult to describe those areas as V-shaped

… perhaps I need help


Thread: WM280v PCD

My guess is that the nominal PCD might be 75mm

… if you share your raw measurements, everyone can have a go at working from those
