Thread: Aircraft General Discussion

I have seen the Vulcan several times - wow!!
Also seen and heard the Eurofighter. When it goes away and turns so you can see the exhausts, the noise just has to be heard to be believed!
They say Concord was noisy. I was at a Stones concert at the old Wembley anmd looked up to see Concord going over, completely `silent` like a dirigible, the concert was so loud. I`ve now got Tinnitus.

Thread: Which slideway oil is best?
22/12/2010 22:55:19
I use a concoction recommended by Guy Lautard (lautard.com).
1 fluid ounce of STP or Wynns oil treatment (makes concoction very sticky so it stays put)
1 fluid ounce of Molyslip oil, this is full of tiny balls of graphite which get into any very small crevice G is a very good lube.
A quantity of EP90, an extreme pressure oil. Cannot remember how much of this - will have to look iy up + get back.
Mix up by shaking vigourously in used plastic oil bottle.
Seems to work OK
 
Regards,

Thread: issue 171

Hi all,
Re my prev. moan 18/12 about ME4393+MEW172.
Monday,20/12, I was in Smiths, Churchill Sq., Brighton as soon as they opened. I counted 9 copies No.4393, 5 copies No.172 and approx a dozen (didnt actually count them) of January EIM. These are the dregs left after the weekend vultures.
I have all 3 by subs but `good ol` snailmail` still failed on Tuesday. I think that as EIM hasnt arrived, it must be our wonderful postal system, not myhobbystore.

David Clark 1,
I am using this `moans thread` to tell you about the letter dated "Dec 3 2010"received today (16th) "Snail Mail" to blame??
1) It appears to be mass produced with half the Market Harboro` address chopped off.
2)"FREE access to our online archive of past issues allowing you to search fo your favourite articles".
 
No it doesn`t!  Even after logging on with my subsciber no., go into "Archive" and it demands another 30 quid. Or what am I doing wrong and if so,  why doesn`t the letter explain how?
 
3) Why does the letter (dated only 3rd Dec) state my renewal will star with "Mar 2011 Iss 174" ? Is this to assist myhobbystores cashflow?!!
 
Sorry to moan about letter whci is very similar to many previous renewal reminders but I think my point no 2 is a serious complaint.
BTW, I very much enjoyed XBN and think bothME/MEW very much improved. Happy Xmas!
Thread: Chemical blackening

There are more than one ME/MEW advertiser who frequently advertise blacking chemicals but unfortunately, cannot name them off top of head.

Thread: Horses for Courses

Hullo Terryd,
You are probably right - Stainless doesnt like seawater. I once read a corrosion article about Stainless screws and boltshaving  been used on a wooden yacht and it was found that where they were hidden from sight inside the wood and permanently wet, they developed patches of corrosion which would eat the bolt away rather quickly until it failed so I understand Bronze is back in favour.

Thread: Fluxes
09/12/2010 09:29:48
Hi All,
Soft Solder Flux. I have not yet tried it but someone "at the club" recommended a flux which he said really does work on brass although the makers say its for copper tube in the plumbing industry; Wickes Active Paste Flux.John

Hi David,
I`m going Fri.  Have pre-ordered items from various traders to collect.
Merry Xmas & Happy Hogmanay!

Thread: Metric vs Imperial - Practical or Traditional?
06/12/2010 10:52:27
Hi All,
Having said what I have in last post, I try to keep to one or other system as required by what`s offered on drawing/in book, rather than constantly trying to convert.
I think the hardest work on say, loco-building, is coping with a drawing which says 16G
brass sheet in stock is 1/16" and the angle to join it is say, 2mm thick. To find length of screw/rivet needed to join them, I would reduce everything to decimal parts of an inch.

Hi All,
I have a cork notice board in my workshop weith various notes drawing-pinned on, mainly laminated to keep `em clean.
Possibly of interest in the metric/imp section is something I cribbed from I cannot remember where;-
3 Horizontal lines, the first marked "inches" and reads left to right, .39  .79  1.18  1.57  1.97  2.36  2.76  3.15  3.54  3.94  4.33  4.72
Second line; 1  2  3    4 consecutively to 12
Third line reads "cm" (centimetres) 2.54  5.08  7.62  10.16  12.70  15.24  17.78  20.32 
22.86  25.40  27.94  30.48
Obviously, in the vertical, the .39 is directly above "1" in next lower line and in turn, directly above "2.54" in the bottom line.
Suppose you want to know what 6cm is, in inches. Look @ "6" in middle row and read
up to top row = 2.36 inches.
What`s 8" in metric? Look @ "8" in middle row again and read down to bottom row =
23.32cm/203.2mm
How easy is this.
Thread: Brake Discs

ady,
Overnight flash rusting DOES take place on unprotected ferrous items. It used to happen a long time ago in my wooden shed workshop, cured by a number of precautions.
I am told that the London tube train rails rust overnight before first morning train.
BTW, its been snowing very fine powdery stuff for hours down here in Brighton and still only an inch or so and main roads black slush.

LBSC once recommended the compressed air escape from drain valves method, I think it was a loco. with `tween frames steam chests.
Thread: passenger carriage boogies ( wheels)
22/11/2010 10:01:20
wots this? Bogies boogying around? ha ha!
eriously, check wheel gauge against track gauge as it sounds like flanges too tight fit `tween rails causing them to ride up sides of curved rail and jump off top.
Thread: Chinese lathes
22/11/2010 09:54:30
How about lathe tools from the exhibition with hard tips apparently `brazed` on - with chewing gum?  `Cos they fell of as soon as they were shown to the work.
 
22/11/2010 09:50:20
Hi All,
I swear a lot (in my workshop) about being such a greedy idiot to buy such cheap rubbish. Many years ago I bought various items at exhibitions, e. g.,  boxeed set of BA taps & dies which contained  something like no 7 BA taps but doubled - up 2BA, to fill the `holes` up. The vendor gets a box out from under the stand, opens it to show its full and then youre stuck with it, when at home you find the fraud. I also bought from another regular well known stall holder, a surface gauge which appeared to be OK til I put the scriber against a rule and the scriber and all its supporting adjustment mechanism promptly moved backwards!  However tightly it is fixed, the whole mechanism still moves. I have never worked out how to correct this and club members didnt know either. I have some nice Dormer drills with a shiny band on the shank where the size is very clearly stamped. I also have many drills, all black, very badly stamped, so bad I have to resort to a strong illumination at an angle + strong magnification to read a lot of them especially the smaller drills. This malaise seemed to start a few years ago when buying Metric drills but more recently to the old Imperial sizes. These drills again came from prominent ME suppliers. No doubt they are keeping their purchasing prices down by sourcing from the far east then selling to `us` at a high price and trousering the diff. Last week on a diff. thread I described the dodgy bandsaw that had to have a mod to stop the blade from keep jumping off the wheels. I could go on and at the same time praise my Myford lathe, Fobco Drill and the mill, all have given complete satisfaction albeit at a price.

Hullo all,
 Ref Niloch, 9/11, the main picture on Machine Mart`s site, of their trolley. This is as used satisfactorily for sometime now by Worthing Model Engineers, who have actually modified it with an extension to the table and fitted rails to the table.

Thread: Best price for Bronze
16/11/2010 10:09:00
Hi all,
I checked some usual ME suppliers and either they apparently did not stock, or were too expensive, for my want. Have ended up ordering  3/4" AF Hex. x 12" Phos. Bronze bar from College Engineering, £11.45 + VAT, in my old copy of their advert and arranging to pick it up from next months ME exbn. - not far away - I live in Brighton. Do you all think this is probably a reasonable price?
Have also ordered for collection from xbn., from Tracy Tools, 5/16" x 40T Tap £3 and Die £4. Nearly fell off chair when I saw prices from some advertisers and since my wants will get limited use, I thought thats all I need to pay. About the most polite remark made by those who know me is that I`m tight!! But why spend  £35 (incl. carriage) when a mere £7 will do?

Thread: Edgar Westbury powered hacksaw castings.
16/11/2010 09:48:46
Hullo Clive,
I have a habit of doing what I call "looking over the fence to see what others are up to."
By this I mean that I will often pick up woodworking or other hobby mags in newsagents to see if there are any bright ideas in other hobbies which could be useful in model engineering. Sometimes I actually `push the boat out` and BUY the mag! Anyway, I have learned one possible reason why my far eastern bandsaw occasionally `drops` its blade. The woodworking version by well - known makes have rubber tyres on the wheels, but my metal - cutting one doesn`t. I have also seen plenty of recommendations to buy/make a BS with the biggest wheels you can as the blade doesn`t then have to bend so much and will last a lot longer. Another is to splash out on a decent blade costing bigger pennies - like most things quality pays in the end. I kept having the blade jamming between the roller bearing guides because said guides wre free to move sideways due to excessive clearance. This was cured by turning up large fat washers to fill the clearance.
