Thread: "TINKER" tool & cutter grinder

I would also like to build this model ( please do not suggest other models in replying) & have been in touch with Guy Lautard who is willing to send me the drawings in PDF format for 50 canadian dollars. I can then print them out on 93 A4 sheets here in the UK. At least that should save surprise import duty etc

While 50 CD is not that excessive - looking at David Clark's picture where do 93 A4 sheets come into it?

Thread: Tich cylinders

I don't think the drawings are incorrect - if for no other reason than so many of the locos have been built from them.

Inlet ports are 3/32, exhaust 1/4 with 3/32 bars giving a width across the inlet ports of 5/8"

The valve is 3/4" long so in mid travel overlaps the ports by 1/16" each side.

With a 9/64 throw eccentric this means the inlet ports open 5/64 out of 3/32 which is fairly normal as ports on LBSC's designs don't always open completely. There is no reason to suppose the extra 2mm or so will be needed - it still will not open the posts completely.

Thread: Replacing a Canon printer with a Brother Laser?
05/04/2021 10:26:41

Consider your computer operating system. I had to dump a Brother Laser printer because it was not well supported for use with Linux - it did work, but much of the functionality was lost. Brother did not provide a LInux driver, only for Windows and Apple

When I stated my present job nearly 11 years ago there were two Brother printers in my room, a mono and a colour both two or three years old and they would still be in use now if it were not for the fact that while Win 10 drivers for both to run connected to a computer are still available, the Win 10 .bin files needed to connect them to a dedicated printer server on a network have not been produced for these old models.

I can't really blame Brother for this as I doubt that many commercial enterprises would be still trying to run 12 or more year old printers in a networked environment!

I cannot comment on today's Brother printers, but comparing those I have seen there is a conceptual difference between them and comparable HP models. A HP toner contains the drum and so is a more expensive replacement than the Brother system of separate drums and toners (and belts in colour models.)

The Brother cartridge for the mon printer is about £80 (genuine - recycled are cheaper) and the drum about £150(ditto) while the equivalent HP for a similar specced machine we have at work is £120. You get a new drum each time but you don't need to change this every time you run out of toner on the Brother. I a nutshell running costs would be cheaper for the Brother but for one thing - You can shake up an HP cartridge until there is no toner left after the message to replace it has appeared and it will continue to produce prints until nothing is printed - long enough to order a replacement. The Brothers have page counters and will stop printing when it thinks the toner has printed enough - or the drum has printed enough or waste toner bottle has collected enough or a belt (in a colour printer) has printed enough. While some of these can be reset you cannot reset the toners cartridge(s) and when recycling them they are clearly not empty.

For work I would use Brothers again, but my mono printer at home is HP running genuine cartridges as I get a new drum every time that way. If I wanted a colour Laser I might go for a Brother at home as well - we'll see.

All laser printers are cheaper to run than the alternatives, but the individual cost of toners is higher at each replacement than for an inkjet printer - so when it runs out you have to find £100 or so which may be harder than finding £5 more often

Thread: Canon printer

I too use VueScan but while drivers are available for my HP G4050  scanner they produce scans of appallingly poor quality.

I bought the scanner off the reduced table in PCWorld and I suspect it was returned for this very reason. Thinking I had wasted (some more!) money I was persuaded to try VueScan. Instant superb quality scans!

I bought a registered version and it has updated with every change of OS since.

A great buy!

Confusing at first blush but ok once you work his system out. I guess you were expected to have a modicum of initiative in those days compared with modern practice.

The use of fractions still drives me nuts as i have to look up the decimal equivalent every time. I guess those old guys had them all in their head, or did everything with a steel ruler and calipers.

That's why my old Moore & Wright micrometer has decimal equivalents engraved on it

Purely out of interest have a look at the following drawing from the description of LBSC's Netta where the axles for gauge O, gauge 1, 2½", 3½" and 5" are all shown together.

in general I suggest lubrication is kept to the minimum you can get away with as all of the oil will end up in your boiler.

Surely not; if you're daft enough to pipe the lubricant into the water side of the pump, yes, but if it's only being used to lubricate the steam side as intended, then you won't get oil into the water side and hence none into the boiler.

Sorry - Yes Nigel you are quite right - Brain failure on my part. Thanks for correcting.

Thread: Starting out a young enthusiast

My daughter left school several years ago when she moved to sixth-form college, but I still keep in contact with the place. As a Technology College it had up to date metal and wood working facilities, but these are being taken out and more computers are being installed because they are moving from CDT or Design Technology or whatever it is called this week to 'Engineering' which means a single CNC machine and a few 3d printers are being installed.

Not quite certain if that is to the benefit of the pupils or not. OK they are more likely to meet a CNC machine in the real world, but if they spend all of their time on a computer and the finished article pops out of a CNC mill like a coke can out of a coke machine, are they not missing out on what is actually happening?

.Jeff a good suggestion as you all know my nickname thoughts come to mind of fitting a De-Laval Nozzle at a certain body part for pure thrust.

Current World record is just over 107mph for a chariot like yours - You need something flat to fit under the seat - Porsche perhaps?

Thread: Milling machines - western-made s/h recommendations up to 2k
30/03/2021 11:17:35

Looking at the drawings for Maid of Kent I cannot see that there would be any difficulty fitting the components for the loco on even the smallest hobby mill - the assumption until the 1980s or so seems to have been that an amateur would use a vertical slide in the lathe for milling as it was not as usual as today for a milling machine to be available (although it usually was in a club workshop of course)

This is not to say that a small mill would necessarily have sufficient power to do the milling on a loco, just that bits would physically fit.

Thread: Southworth Pump Lubrication
30/03/2021 09:06:15

For his steam pumps LBSC drew a tiny displacement lubricator - it is described in the Live Steam Book (aka Shop, Shed & Road) and as far as I recall it was 5/16" diameter by about an inch tall - I can't lay my hand on the book at present to check though.

in general I suggest lubrication is kept to the minimum you can get away with as all of the oil will end up in your boiler.

Thread: Whicht "Fonts" were used on th e Somerset & Dorset Joint Rlwy??
29/03/2021 11:00:16
Posted by Tim Stevens on 28/03/2021 17:56:43:

And for the pedants among us, a font is a set of type of one design and one size only. If the printer needed a different size he bought a new font. Computer designers got this wrong (as in so many other things).

Cheers, Tim

Having shared an office with printers for several years, one of whom taught typography, I can assure anyone that cares that the term 'pedant' is scarcely strong enough when professionals discussed the subject.

Talking about the Times family of typefaces, to take just one example, there would be arguments as to which of the different commercial versions (before personal computers there was no such thing as a 'free' font, they were all copyright to different companies) was best, with aesthetics, ease of reading and inkholding all entering into the fun.

Nick

PS - Different sizes of metal type, nominally of the same typeface, did not always use the same glyphs for corresponding letters - these were sometimes simplified in smaller sizes.

Thread: RH vs LH threads
29/03/2021 09:33:14
Posted by John MC on 29/03/2021 09:27:05:

I thought it time to ressurrect this thread. The choice of LH vs RH threads on a bicycle is done for good reason. Considering the pedals, RH thread on RH side, the often made assumption is that the pedal rotates CW on this side , it doesn't, it rotates ACW, the direction that will undo a RH thread. So why the RH thread?

A couple of the replies to my original question have "got it", what I am looking for is a simple explanation. So, once again over to you guys.

John

A pedal will indeed turn anti clockwise on its spindle, however the spindle is not totally frictionless so the force of a power stroke from the rider will tend to tighten it in the crank surely?

I suggest looking to see if an axlebox is sticking in the horns.

If not look to see where the boxes are vertically in the horns - you have added weight so they will be higher up in the horns than before so does it run if the loco is supported under the boiler to take some of the weight off?

Regarding he smokebox front I don't think it was ever described in full or drawn in the magazine.

Cast frames or tender frames were usually the production of individual suppliers - if I had to guess I would suggest perhaps W.K.Waugh, trading as Wilwaugh - but this is only a guess. These 'extra' castings were something he often produced alongside the standard ones. Long gone and when his passing was announced in ME there was no indication that his patterns were taken over by anyone else.

Thread: New car - or is it a wheeled computer?
26/03/2021 09:37:54
Posted by Howard Lewis on 26/03/2021 09:31:08:

Even small ,cars are not immune from the "I have invented a new whistle, so I will fit it, even when not needed" syndrome.

My wife and I each run probably some of the smallest and cheapest cars on the market.

One of the features is a speed limiter. Tried once and considered to be a possible danger. (Impossible to accelerate out of a developing emergency ) based on the proposition that my motor control, and powers of observation are so poor that I cannot see the speedo right in front of me, or lift off the throttle pedal.

Wish that they had spent the money on providing a back shelf that does not fall out when anything is placed in, or removed from, the boot!

Like predictive spelling, I do not believe that a computer knows better than I do what is in my mind.

(My wife abandoned one, otherwise excellent, mobile phone because the predictive spelling cannot be disabled )

Next thing, will it refuse to close the doors automatically until my fingers are out of the way?

So much for market research driving what WE want

I'm with you Howard - The criteria for my present car when I bought it 8 years ago were

  1. Does it always start?
  2. Has it a good heater?

In addition it is the first car I have had with Air Con (even if it does not work if kept unused) and Bluetooth and I have grown to like these as well.

But the interesting thing about your comment on doors and fingers is that in the past people WERE trapping themselves in electric windows which did not stop, and not only small children!
