Thread: Poly-Vee Belts
10/09/2019 22:09:53

As with Vee Belts there are various different sizes of Poly Vee Belts.

Let me have your details via a PM and I will send you a PDF catalogue showing all the details.

Thread: Zinc plating
07/09/2019 15:16:22

I will second that.

Many years ago my dad thought he was being clever by making the boiler lagging sheets for our Aveling & Porter steam roller from zinc coated sheet, he assumed it would last longer in that environment and it probably would have done.

Etch primer was not very common back then, and the nice new shiny black coach paint and pin striping all started peeling of within a few weeks !!

When we restored the Fowler road loco, we used blued steel sheet for lagging the cylinder block, that looked superb.

Thread: Any one used a digital microscope for micro turning on a lathe
07/09/2019 11:27:40

I almost universally use a clip on magnifier in the workshop, I occasionally use the optivisor headband but find it not as comfortable to wear for long periods.

I have good quality Zeiss clip ons in 4 & 6 dioptre strengths.

These when worn with my +2 reading glasses are great for really close up stuff working at about 150mm range.

Most of the time though, I use one of these with the 1.5x lens fitted and that gives me a working range of about 250mm, they are cheap as chips so if you break or scratch one it does'nt matter too much.

**LINK**

Not wishing to damage my eyes by using a £3 bit of plastic, I took it to my optitions yesterday when choosing some new glasses for the workshop. He put it on his lens strength testing machine and told me it was spot on and that he was quite impressed at the quality for the price, so carry on using it with no problems.

Just a thought.................If a stereo microscope is used for watchmaking, does that make it a Horoscope ?

Thread: Pultra 10mm Collet Blocks
06/09/2019 11:34:07

Jason

Fair comment.

I have made the nut so it is machined on both sides and also so that the collet cannot poke out of the end for that very reason. I did wonder about a recessed nut, but thought it over complicated the design.

This is a solution I made in the late 1980's before going back to a 4 Tool Turret, based on George Thomas's design.

I still use mine on the Super 7, its a brilliant design in my opinion, why did you revert back to a four way toolpost ?

I made Georges four way turret years ago, but did not really like it to be honest.

Thread: Pultra 10mm Collet Blocks
06/09/2019 11:14:30

OK, if anyone is remotely interested, here are my Solidworks drawings in JPG format.

Just bear in mind that I have not actually made them yet, so they may possibly change.

The plan is to bore the 10mm collet hole and taper in the square and hexagon raw materials, then use a mandrel to hold them in the dividing head to finish the flats to size on the milling machine.

Thread: Any one used a digital microscope for micro turning on a lathe
06/09/2019 10:52:50

Definitely not the cheapo chinese digital ones for me, I have borrowed one to try out on both my Boley watchmaking lathe and my Pultra 1770. I could not get on with it in either situation, so am sticking to my binocular microscopes.

I would be very interested to hear and see how other people have mounted a binocular microscope though.

Mine is on an old angle-poise type lamp bracket, but is not what I would call ideal as it can flex slightly when in use.

Thread: Why does the micrometer have a second knurled segment
06/09/2019 08:47:36

Brian

You are right of course, but the OP got his answer in the first couple of replies and I am sure he will be able to see that this is just a bit of friendly banter. If not, and with all due respect he is probably asking the wrong people.

My Mitutoyo 1" Mic doesn't have a second knurled ring.

Should I not be hammering with it in that case wink

Thread: Pultra 10mm Collet Blocks
05/09/2019 23:52:14

Yes Michael

That's the sort of thing, in fact I have just this minute finished drawing a set up in Solidworks 3D CAD.

Watch this space !!

As I suspected.

The only thing I have managed to find is on this website, he calls it an upright collet holder but it is not really what I am after.

**LINK**

Looks like I will be making my own then.

OK I know this is a long shot, but before I set to and make some, has anyone come across any commercially available ones.

What I am talking about are the four and six sided blocks to hold collets, they are typically available for ER and 5C etc.

Those are too bulky for my needs, and I would like a set to take my 10mm Pultra 1770 collets for doing really small work on the Boley jig borer. I have every imaginable size and shape of collet, so it makes sense to use them on more than one machine.

Thanks

Phil

Thread: Just for fun what’s this stuck in my tyre?
27/08/2019 23:05:04

Dunno what that is, but I had a bizzare puncture the other day that cost me a new tyre. It had 4" nail through it.

Now that may not sound all that strange, until I tell you the head was inside the tyre with the pointy bit on the outside. work that one out ?

Thread: Tempering Rivet Snaps
20/08/2019 21:30:45

Andrew

Just looking at the wheel rim photo above, it would appear to have slightly bulged the rim inwards on the two rivets nearest the edge. Or I could have just imagined all the above !!

I reckon you will have got some really good strong joints if the rivets have expanded with such outwards pressure in the holes like that.

Bob no longer runs Southworth Engines, you need to speak to Blackgates.

Thread: Digital calipers made in same factory?
14/08/2019 22:18:42

The CE mark on the Moore & Wright looks incorrect to my eyes, the letters are too close together. All that means is "Chinese Export"

The CE mark on the cheap ones actually looks to be the correct spacing as far as I can tell.

Google it if you are not sure what I mean, A correct CE mark is very specific.

Stefan Gotteswinter is worth a look too.

Thread: Parting off

Yes, you can grind the nose of your perting tool so it has a very slight angle to it. That way the leading edge will break through first.

You will then leave the lip behind on the parent bar. And then follow through with the cut to remove it.

I have just sent the details you need to make contact, the BCA is in excellent condition and is on the original makers stand, my friend is also a very accomplished clock maker, so you will have an interesting conversation when you make contact.

Thread: Hello from Yorkshire

Hi Ben

I too work all day every day with SW2018, we have just upgraded from 2014 last week !!

Where are you based in Yorkshire, I live in West Yorks, but work just over the border in N Yorks.
