Thread: Just for fun what’s this stuck in my tyre?
28/08/2019 09:58:10

Ah, 'hippy crack', N2O - you have no doubt parked in a quiet corner of a public car park, where the sniffers gather.

I suspect some smart Alec deliberately wedged it under your tyre at an angle, so it did what it did and penetrated the tyre.

The constant pitch threads are just a subset within Unified, as are UNS, the specials. They aren't in common use, but a standard does exist for them.

As you correctly stated earlier, BSCY is also a constant pitch thread at 26 tpi, as is BSB (Brass), which, although also 26 tpi, is confusingly NOT the same as BSCY!

I have a number of reference books I use for for threads - Machinery's Handbook, Kempe's, Newnes, IMechE, but my go to first choice for the most common threads is normally Harold Hall's Metalworker's Data Book, no. 42 in the Workshop Practice series.

Thank you for the prompt replies. Never heard of 28-UN who knew........ Think that one will be in the "come in handy" section of the tap drawer, never to see the light of day again.

Thanks again.

Rich.

You probably have heard of UN threads.

UN stands for Unified, and is is the standard US thread standard.

Within that you have UNF (unified fine)

UNC (unified coarse)

UNEF (unified extra fine)

UNS (unified special - custom/non standard UN threads drop into this category)

Thread: Things I should know cutting various materials on lathe

Buy some reputable books on the subject, and have a read!

I don't mean that facetiously, but look through the 'Workshop Practice' series of books, everything you need is there, start with nos 3, 30, 34, 42 and 45.

Thread: Lathe rigidity
25/08/2019 19:52:12

I agree, and to to reinforce Vic's comment, if you have a 'slightly sloppy spindle' and poor finish, why is the collet chuck so far from the headstock?

If you don't mind me saying so, you have much more than desirable tool protrusion with that setup in the penultimate photograph, and are only clamping the insert holder with two screws, which is because you have to pull the tool holder out to clear the other tool holder dovetail on the tool block.

If you turn the toolpost 90 degrees and use the other tool dovetail, you will have around 10 mm or more reduced tool protrusion, and a more rigid setup, with correspondingly better results.

Martin,

I always make my back plate register undersize by around 5 thou. If you make the holding screw holes oversize, then you have a cheap Griptru chuck that you can adjust to get zero run out for any work diameter you want.

Andrew.

Yep, exactly what I was going to say! yes

That would be "Purple Poison" built by 2WheelsMiklos.

It looks like when it left their custom shop, it had a rather more direct linkage. [ ... ]

Good Grief ...

I wonder who supplies their MOT certificates

Have you tried the manufacturer - 600Group/Colchester Machine Tool Solutions?

And obviously my borrowing/lending books comment was not pointed at you, Christopher, or anyone else on here smiley

My policy is never borrow a book as it lead to falling out if it gets forgotten, but your a mate for offerring.

Chris

Same here. Have had a few fallings out over exactly that in the past (books that were borrowed from me, in one case the borrower having subsequently 'lost' it).

I would use a slot drill for that. Clear the swarf regularly.

What about a Myford 254S the metric ones are cheaper than the imperial ones. Only secondhand machines now. Very happy with mine.

Nathan's brief included 'good sized spindle bore, perhaps 38mm'. A 254S misses that brief by 12mm wink

I had thought someone else would have answered by now!

Just been out in the workshop and checked, mine is 2.25"

I suspect the .0001 was a typo for .001 wink

Thread: First Lathe
06/08/2019 20:45:44

If you are looking at Warco, why haven't you mentioned the GH1322?

Bigger swing than the two you mentioned, smaller footprint, and if you want a metric 3 phase one, and you say you can fit a VFD, it has the benefit of currently being £650 off!

Thinking of your poor old fingers, please use a brush to clean the swarf off before before poking your fingers in brass milling swarf wink

Bit small the reply

Vertical along a 75mm length

When quoting, start your text below the left hand vertical line on the quoted part, you will then get full size text - as here

Re the lines on the work, do you have a larger diameter cutter you can use?

Also, are you winding in the feed evenly? If manually feeding, there is a tendency to speed up and slow down the hand wheel rotation if not careful, which can leave marks.
