Apparently the customs papers for a chap importing hydraulic rams into Zimbabwe were maked "Livestock"

Rob

I think Colin is making the handles as well, so he can thread the ends to suit metric balls if needed.

Rob

Just another bit of praise for Tracy Tools - ordered a number of drill bits late yesterday afternoon (replacing the broken ones in my sets) and they arrived by Royal Mail before lunch today.

Hi Colin

Just had a search on Ebay for "plastic ball handles" and there's quite a choice available.

Rob

Hang on a minute... these sort of questions sound a bit familiar

Nice one Steven.

Rob

SOD - in this case heavily optimistic, as a) I've got a Myford 4 jaw chuck (wouldn't want to drop it on my foot), and b) I don't regard a 4 jaw as anything approaching an inherently precision device, more like a spinning clamp adjustable in two axes.

But still no reason to abuse them

And to hijack the thread, as is my wont, I've just cleaned up a Taylor 3 jaw which has a dished front face and strangely angled jaws which move closer to the back of the chuck as they close. Not seen anything like it before.

Rob

Edit - just found this video on how to repair/replace four jaw chuck screws

I really miss 405 line VHF TV...

Coincidentally, BT Openreach are currently installing fibre down our street - firstly laying 3 inch (approx) dia plastic pipes and then pulling the fibre cable through. You can see their point, really, the fibre is cheaper and takes up much less space than the copper cables.

And look forward to the time when all that scrap copper they remove hits the market - prices of model engineering metals should drop dramatically

Rob

Agree with Dave S. Like a building, it's only going to be as good as the foundations. (Waits for someone to come up with an example that disproves it... )

Rob

It's a four jaw - presumably not self-centering - so not much chance of it being scrap.

Rob

The O-ring solution is probably the best way, but I do like Michael G's suggestion with the magnets

Rob

Just to drift slightly off-topic, the funnel shape of a blunderbuss was more to make it easier to load than to scatter the shot over a wider area. Similarly with sawn-off shotguns, it's to make them easier to conceal, not spread shot.

Back to the dividing heads...

Rob

Can you still get ammonia? Not seen it on sale for years.

Rob

I like this Double TT spray, which leaves a bit of a residue, for things not in regular use. And GT85, as mentioned above is also good (smells nice too!) and seems to be identical to the much more costly Wurth spray, for things used daily, as it can be wiped off easily - if indeed you need to wipe it off at all, probably not necessary in most cases.

Edit - in your nice warm environment, possibly just a coat of Renaissance wax would suffice,

As a start, make a tapping block. Adam Savage has a video here which covers the subject.

Excellent point, and one that probably has not been taken into account. I seem to recall left and right-handed ground marking knives for woodworkers - fire up the Google machine, we may be looking for those next

Rob

Well said Jon

Rob

I quite often have the radio on in the background, and find myself talking back to it...

Rob

I would have thought this one from Level Developments would be more than accurate enough, and only half the price you quoted.

Thanks chaps, the forum wins again. Like Michael, I was thinking some sort of gauge.

Cheers,

Rob
