Thread: Latest forum posts
13/06/2017 15:36:49

The latest forum posts list is handy, but Bazyle's suggestion of making the "more latest posts" your default setting for the forum should do the trick. Would save you 'one click' every time you access the site, so not that big a deal.

IIABDFI seems to be the state of replies. YCPSOTPSOTTBNATPATT applies?

Thread: The thread of assorted Keighley lathe questions
12/06/2017 22:00:25

First - doubtful.

Thread: Left hand thread nut for Pinnacle Bench Grinder
12/06/2017 06:32:04

Just a rain check.

 

 

(7/10th inch) and over than length I count 9 thread ridges

 

 

 

 

How many valleys? Wondering here whether first ridge counted was number zero.

Thread: Milling cutter ?
11/06/2017 18:30:57

Yanks often say "keep it simple, Sugar". You choose your acronym conversion. When teaching I use "keep it simple, Sir" as an alternative to the "stupid".

Thread: Can an electric power steering pump drive a hydraulic ram
11/06/2017 16:46:34

This thread might be a starting point for you musings:

http://www.practicalmachinist.com/vb/general/ot-power-steering-pump-question-148528/

Likely referencing mechanically driven pumps, but maybe of some use.

I reckon a portable leccy generator might be a better alternative to messing around with power steering pumps and 12V batteries?

Thread: Ouch... electric car crash
11/06/2017 10:28:09

Question might be was it a left or right corner he stuffed it. Now there are more vids, one shows it as him attempting to turn right. Perhaps he didn't know which way to turn? Maybe someone moved the goal posts - but he scored an own goal either way!

There is a 20 second clip of it on u-toob.

Two wheels? If so, remove the other side and check that?

Thread: Worth Rescuing?
08/06/2017 12:35:26

First thought that came to my head was a roller to shape roofing valleys. Likely a million miles off the real use!

Thread: Machining Precision Angles

Joe has umpteen handy tips for doing all sorts of machining operations.

Thread: Knowledge
07/06/2017 22:21:38

The one thing I have either missed, or has been omitted is safety. You can break as many cutters, scrap lots of bits, etc while learning but you need to be safe. You have not offered information on what you have bought. Even small machines can kill or maim.

U-toob videos - they are not all good - and a search for any new procedure on the forum, or elsewhere, for tips and advice is always well worthwhile.

If you are not sure, ask someone or somewhere before proceeding. Enjoying making chips is good. Breaking tools is annoying, but all part of learning. But don't learn the hard way about safety!

Donation to local FB? Is it still in test? Pub suppliers? BOC?

Thread: Rusty lathe for sale
07/06/2017 07:25:36

Good value at 1p!

A quick scrub up, paint job over filler and metal and it's a good 'un. On epay, with a starting price of goodness knows how much, in a week or so!

The gears might be good, still, or could be re-hardened and tempered if it was actually hot enough to affect them.

Thread: Split dies
07/06/2017 07:04:25

Look at it from the common sense perspective. What die (or pair) is in the tool at present?

Ooh, can't read it because it is in the wrong way? Does that make it fairly obvious which way they should be installed?

Like buying a newspaper or a book and all the names/titles only being hidden inside somewhere!

Thread: Hello from Northamptonshire.
06/06/2017 10:19:05

Welcome to the forum. I'm nearly from Northants, but not quite. On Saturday I went nearly seventy miles, by road (not as a crow would fly), and was still only at Croughton! Engineers tend to be a little more precise than that (Rutland being the exception, maybe?), so north, east south or west?

Thread: BA's VW moment
06/06/2017 10:04:05

Shirley, the system should have been designed such that this could not occur?

Not quite sure who Shirley is/was but she must be to blame....

That problem would be about as basic as starting an automatic car while not in either 'park' or 'neutral'. One could expect a crash!

Thread: Piston rings muddled up
04/06/2017 10:52:33

Compression rings have other duties than simply confining gases within the combustion chamber. They also help regulate the amountvof oil passing upwards in a four stroke engine and transfer heat from the piston to the cylinder walls. This latter duty indicates that the piston is rsther hotter than the cylinder walls. Therefore the rings will expand rather more than the cylinder. Interference, rather than sliding fit can lead to engine seizure, not just excessive wear.

Ahh, I see it is fairly modern engine design, a separate head - not a blind cylinder. Look at the B&S engine ring types used. That may be useful.

Or this may be more useful:

03/06/2017 23:02:59

doing up a Suffolk mower remember?

Nope!

Not replacing the rings with new? What is the ring gap in an unworn part of the bore? Can you see a line in the ring groove to determine where the inside stepped ring fits? The more worn (on thickness) is likely the top ring.

There won't be a ridge dodger if original, so that step is likely bottom side of second ring. You may need a ridge dodger if the bore is worn and you fit new rings.

Are they square or tapered rings (if not appreciably worn)?

You might need a magnifier as well as your reading specs. If there is metal displaced on the outer edge of the ring (sharp edge) it will be the bottom of the top ring.

Thread: How should we describe non-metric tooling?
01/06/2017 09:35:48

A pair of horses' arses to determine railway track width. Two ox, needing a rest when pulling a plough, to determine the furlong (furrow long). The Americans losing a spacecraft by mixing two different measurement systems.

All arcane examples of unit determination or what might happen with mixing systems. Even imperial bearings have been metric for decades, apparently.

How often do you see a u-toob where someone converts other fractions of an inchoto the simpler decimal measurememt (thousanths). Drill bits in a box, marked as fractions but used as thousandths of an inch. Not many inch 'micrometers' in 1024ths!

Americans might call their system anything they like; they might claim some units are English, Imperial. American user standards, etc. But the still use the BTU (British Thermal Unit) as a measure of energy. Go figure....

Some, I know, dislike metric because "It is French". How quaint, or peculiar (and luddite)!!! I hear children stating their height and weight in old units, but don't have a clue as to how many pounds in a stone or even feet in a foot! And the only pints you might find are beer volume or blood donoring (actually 400g). Even spirits and wine are dispensed in metric volumes these days.

Even rugby- a real British invention, for sure - went metric decades ago. Cricket pitches may be 22 yards between the stumps but that does not change the fact that those stumps are 20.13 metres apart. Are tennis courts imperial or metric these days? I would guess that most professional golfers are metric users as well?

Metric rules, particularly now as SI units. But the computef industry still uses 1024 as a standard....

Call your tools metric or 'old units', because that is what imperial units are - old units.

Thread: Max speed for an 8 inch 4-jaw?
29/05/2017 07:15:42

If the OP were to state the actual mass of the item to be turned, the real offset from the centre line, dimensions, material, density, and more - he might get a more specific reply.

I would not countenance making a judgement on the information given. Rotating devices are dangerous enough without stretching close to mechanical limits. I note that a 4" item would have a surface speed of around 2000' per minute. Just those two off-centre jaws will have a considerable (non negligible) effect on the balance of the chuck.
