Thread: Canon Printer in Aldi
12/09/2018 19:01:45
Posted by HOWARDT on 12/09/2018 16:07:21:

Ady1, try using thicker paper. I've found using 90gm paper reduces the problems of incorrect feed, 70gm seems like tissue paper these days.

Totally agree. I buy paper and printers for our school and some brands of 80g paper just will not feed in any printer others will feed in some printers and not others. Some mono and colour laser printers are worse than inkjets.

The big issue is that inkjets need to be used. I have scrapped Canon, HP and Epson printers that have had gunged up heads. Apart from printers where the head is in the cartridge (which are prohibitively expensive to run), all have replaceable heads, but at about £90 for an head for a £50 printer I don't bother.

Canons are not especially bad for slipping rollers - they can always be cleaned if necessary and they are not the only ones - HP were supplying roller cleaning kits for deskjet printers already in the 1990s.

If the waste ink bottle is full on an inkjet it is probably not worth stripping the printer down to replace it. Those in Lasers are easier to get at, but take care as the toner dust itself is carcinogenic.

If you want to print photos, particularly on photo paper, then the inkjet, providing you use decent paper and keep using it, is a good choice - otherwise put up with the lower image quality from a colour laser. If you only use mono then a mono laser is a no brainer.

There is a physical law which says that if you do break it, it will be in the last hole on the final operation of the workpiece.

Believed to be Newton's Fourth Law (of the eternal cussedness of things; sometimes attributed to Sod)


As a teacher I prefer the version of the law that states :-

A piece of toast, when dropped, will always land butter side down - UNLESS you are trying to demonstrate this to someone else!

Thread: Mosaic Mini lathe
10/09/2018 17:50:03

The spec on the front of the lathe pictured in the Amazon link above does not match the spec described by the seller and both of these are different from the spec described by at least one of the reviewers. Although both reviewers gave high scores, reading their comments they have been very generous to say the least.

One more vote for sticking with the established sellers.

An alternative could have been to use tubing, rather than bar. I really need a cupboard full of off-cuts; I haven't located a suitable scrap metal merchant near my new home. There was a brilliant place in Brighton that would sell useful stuff at really good prices. eBay is not a cheap source of bits and bobs,

With all due regard to your personal privacy, what general area of the country are you in? Perhaps someone could make a suggestion?

My personal experience is that metal merchants (as against model engineering suppliers) keep offcuts and usually, if you have bought something, will sell these to you at scrap prices as that is all they will get for them.

Thread: Understanding plans.

If in doubt ask here. There are a lot of very experienced people here (not me!!) who seem happy to help.

Remember that sometimes there is the odd piece of information left to 'experience' and not clearly drawn on a plan so ask if you are not clear.

No 13 in the 'Workshop Practice' books is 'Workshop Drawing' by Tubal Cain (Google for availability online) which is clear and comprehensive.

Got a recipe somewhere involving ground up chalk and Gum Arabic. I'll see if I can find it.

Some recipe! These TV cookery programmes are really getting a bit weird - bring back Delia I say!

Thread: Hackfly Requires a Rebuild says LBSC

On the other hand,the AK47 appears to be highly regarded everywhere.

But not presumably if it is pointing at you!


30/08/2018 09:27:13

In the early 1970's a member of the Nottingham SMEE built a Hackfly (Sorry if you read this but I can't remember your name) working full time in a gap between jobs I believe.

It certainly ran on the Valley Road track and I drove it once but I never saw it loaded to capacity to see just how much it could do.

Incidentally there were other articles by Turpin in ME on 'innovations' during the 1950s, and he had been a contributor since 1921.


Thread: Win10 Home / Linux LAN - anyone got one going?
27/08/2018 08:27:48
Posted by Neil Wyatt on 26/08/2018 22:41:43:

I've just got Astronomy Linux working on an old laptop. It uses Ubuntu 16.04.

I won't go through the details but it was a long , traumatic haul and I could not have done it without someone handholding me through the parts where Ubuntu help was just sending me in circles. It seems impossible to install wireless card drivers without an internet connection, had to find an ethernet cable in the end!

Not hugely impressed at this point.


Hi Neil - been there! Out of interest were you getting your WiFi drivers from Astronomy Linux repositories, Ubuntu or the manufacturers site? All three ways can raise different issues.

Despite having used various versions of Linux since 1994 I am still not convinced that hardware support is always as easy to find and put into place as it might easily be made to be. But please persevere as the underlying system is well worth the effort.

I was unaware there was a specific distribution for astronomers until you mentioned it - Having just looked it up it seems useful, and the flexibility of Linux in enabling all of the applications for a particular area of interest to be set up in one go is one of the benefits of the system.


Thread: Solder..?
24/08/2018 10:35:33

Cuttlefish shell (you know - like budgies gave in their cages) was used for making small single sided castings - press the original pattern into the soft side and pour your solder into the depression that is left.

Alternately try some lost wax casting by covering or investing a wax pattern in plaster inside a short length of copper tube with a funnel like entrance at the top. Heat until the wax has melted away and then melt some solder in the funnel. Clap a metal lid on with a circle of wetted cloth in it (I used to use the lid of a pipe tobacco tin) and the steam will force the metal into the mould. Break out your finished casting. You will need more heat for this though.

This method was used by dental technicians years ago and I attended a demonstration at the Nottingham SMEE in the seventies before trying it out myself with what was then called students metal, however I suspect that you will need absolution from H&S to do it today!

Thread: Mitutoyo'ising' cheap Aldi Calipers
23/08/2018 21:21:08

Cheap modern tools can often be as accurate as more traditional ones but the finish!!!

A real life example:

Lost 1960s Moore and Wright 1-2" micrometer.

Bought replacement Moore and wright 1-2" micrometer. Pleased with purchase.

Moved workbench and found original micrometer. Difference in feel is bigger than the whole world!!!

The feel of the old one is so much nicer. But then, out of curiousity, I tried them both on a some of slip gauges and the new, rougher feeling ones seem to be more accurate, not an error that can be adjusted out either, but different across the range.

If this was an exam question it would be followed by - Discuss!!

Thread: Aluminium eccentric
23/08/2018 21:08:06

Thanks for answers (and any in the future too).

My reason for asking was what about the long term issues as taking wheels off axels, press fit or Loctite is a non-trivial action in my opinion and thanks for some useful comments on this from you both.

23/08/2018 19:23:34

Curious to know whether people consider if aluminium would be a suitable material for items like loco axle pump eccentrics, riding car band brake drums and items 'fixed for life' with pressed on wheels either side?

Lighter, less corrosion (perhaps) and possibly a better bearing material than steel???

Thread: Marconi F3049-02 : Joystick Controller
23/08/2018 08:51:38

Standard PC joysticks attach to a 15pin D connector on the motherboard or soundcard and consist of a series of variable resistors that are adjusted as the joystick is moved, providing an analogue voltage proportional to position.

The 9 pin connector was found on Atari and similar machines and consisted of switches for up, down, right and left. Software within the computer/console polled these over time to provide positional information. Google Atari joystick pinout for images of the connections.

Without more data it is hard to do more than answer your last question with a no as the connector is not correct. Whether it would work on a games console I can't say, but instinct suggests I would be surprised if it did.

Thread: Pen names

A similar enquiry - I have just noticed the book Workshop Hint & Tips on the shelf - a Model Engineer Handbook, published in 1957 and reprinted in 1970. This is by Geometer and I think is a set of reprints of articles in ME - but does anyone know who was Geometer? The introduction says the name covers the identity of 'a professional engineer who has had many years of experience'

A good read!

Thread: What did you do Today 2018
19/08/2018 15:06:45

Not the end of the day yet, but it has been a busy weekend so I suspect not much more is going to get done.

Friday down to the Bristol exhibition for the day.

Saturday some time in the club workshop followed by public running on the track.

Today Rugby radio rally where an old but new in box boring bar and this interesting book (pub 1951) for £3 the pair!

Thread: Win10 Home / Linux LAN - anyone got one going?
18/08/2018 08:05:43

For a robust 'standard' system Samba is the way to go - a so an so to up but reliable and secure. Another quality solution is to use a NAS drive independently set up on your network that both systems can access.

For a 'quick and dirty' solution set up a simple webserver on your Linux box - Apache but no PHP or MySQL needed and connect to that from your Win10 Laptop.

Thread: Thermic Syphon
16/08/2018 11:41:44

Nicholson gained a US patent for his thermic syphon in 1928 and this is a link where some of its advantages are described.

As to other locos tyhat used them Gresley designed the V4 2-6-2 in 1939 (his last design). The first member of this class, 'Bantam Cock' has a traditional copper firebox while the second had a boiler with an all welded steel firebox and thermic syphon. Why? Perhaps because it was felt that the increased efficiency would counter the lower heat conductance of a steel firebox compared to a copper one. Alternately Bulleid, who had been Gresley's assistant until he took up his position with the Southern, might have considered the case for the thermic syphon proved, but adding them to a copper firebox problematic so the welded steel firebox of the SR pacifics enabled their inclusion. It is difficult to determine exact reasons after this amount of time.

A final thought, while not professing to any expertise in boiler design or construction, the elimination of design features such as combustion chambers or syphons would surely make a boiler 'not to an accepted design' and raise more questions than it gives answers.

Thread: Wheels to Axles - locomotives

Posted by Clive Foster on 14/08/2018 13:30:20:

I often wonder what the actual strength of such threaded keys is when compared to more conventional keys. Or even a simple round pin held in place by a bolt and washer.

Possibly the weakness is even more important than the strenth. If the parts ever have to come apart a socket grubscrew can split and become immoveable, as the components then become too. A plain pin is no problem as after applying some heat the wheels can be pressed off and the pin falls out!
