Thread: Recovering from disaster
20/02/2020 11:47:09

An additional thought re disasters in general - one of our contributors some years back suffered a garage/workhop fire which gutted the building. He was Terry D (?) and I haven't seen anything from him for some time. His original posts may well be of help in forming plans etc.

Where to start ... both in actuality and summary?

In my case it was just one part of a complete destruction, so it wasn't the first consideration for recovery. It was actually three workhops, one 14 x 8 wooden shed and a larger, concrete and asbestos garage with an adjoining 6 x 10 'build-on'.

The wooden stucture ended as shown, complete with contents(!) and a kind neighbour 'secured' it as shown. The other two were both damaged from inundation.

The first action was by the 'recovery' team who deal with clearing up the initial mess and they were very helpful but, perhaps, disposed of some items too readily. It's not a good time to be making decisions. There were a number of new and nearly new items 'went into the skip'. Once the cleanup was complete, recovered items needed to be stored securely an, eventually, losses assessed ... how's the memory!!?

Individual circumstances are so diverse that it is impossible to offer hard and fast rules for action but one suggestion could well be to make an inventory - ...I hadn't!

Final point - at the end of the day, it is only a collection of objects which may, or may not, be replaceable.

Insurance aftermath will depend on the company involved - not an area for optimism!

Thread: Linked belt for Myford 7

+1 for Martin's observation - can't now remember which way is correct! I have a Brammer for motor to counter-shaft and no problems. Can't use them on main drive 'cos it's a Trileva.

Thread: Why?
18/02/2020 17:55:28

Thank you to everyone for their replies

Michael - as you will have gathered, the 'double-sided' form is correct.

From the info given, I had a look through the 1974 edition of Serjeants' tool catalogue and they have a similar set labelled as 'American pattern'. I still wonder why the stock is so much heftier than an equivalent 'normal' stock and die set.

Thank you all again

Thank you for the replies - Phil, that sounds reasonable; what I find particularly odd is the extra size versus 'normal' dies stocks. Clive - the lower one is the obverse of the upper and each is similarly formed.

I suppose the real question is, what process would require this specialised form and the extra heft (twice as much) to produce the thread? Odd!

Recently bought a set of dies with die stock. Something of a surprise when they arrived and I discovered the size and form. Not seen similar previously and don't understand why they should be made so. Range is 1/8th to 1/2. Any thoughts, please?

Thread: Did i make the right choice buying an old banger Myford lathe.
15/02/2020 14:12:20

As I recall it, the saying was "comparisons are odious" and none more so than Spitfires and Hurricanes. Superficially for the same purpose, they were, operationally, 'chalk and cheese'. The Hurricane was, essentially anti-bomber, the Spitfire anti-fighter. Each served its own purpose well. The speed advantage of the Spitfire came with a complicated repair process for battle damage - the Hurricane needed a few patches of maddapolam and a coat of dope - almost 'apples and pears'.

It is constantly demonstrated, on this forum and elsewhere, (not by me!!) that quality of output is dictated by operator skill, rather than quality of machinery.

Thread: What a nightmare
14/02/2020 18:35:00

Only just come across this thread and, specifically, S O D's extraordinary views re. ex-Servicemen (and, presumably, women). I possibly missed somehing because I stopped reading after the first ludicrous assertions.

He appears to claim expertise in some undefined area but I would respectfully suggest that assessing ex-Servicemen is not one of them! Based, apparently, on one anonymous 'experience' he damns a cohort of exceptionally well qualified people as being somehow unable to operate without guidance and lacking motivation.

Having left the 'cosy protected world of Service life' after some 34+ years, much spent dangling on a wire attached to a helicopter (and waitng for 'higher orders' as to how to rescue the unfortunate victim!!angry) I tentatively ventured into an area of expertise only marginally related to previous experience and only managed to cope for a further 12 years!

On a personal basis. my user name is based on my working experience of having operated in every aircraft crew function apart, from gunner, plus Air Traffic Control, and technical and handling expertise on 3 and 4 engined aircraft with both major airlines ... and, yes, I do understand the concomitant dictum!!

S O D's 'drected supervision' must have been light indeed, 'cos it didn't impinge noticeably on the majority of my working life - Service or civilian! What on earth possessed him?

Thread: Delays in Shipping from China
07/02/2020 10:22:40

Had a message from a Chinese supplier that my order had been "detained by the Security Company" - presumably part of the ongoing restrictions. Going to be a while before things are back to normal.

Thread: New Nimrods arriving
06/02/2020 12:42:46

Aircrew in the Middle East in the 50s had to carry sidearms plus 6 rounds. My firearms skills were more throwing than firing, so I took 'someone's' advice that I leave the first chamber empty i.e. TWO pulls to fire. Did so for nearly two years before another 'someone' pointed out that we were issued with Colts OR Smith & Wessons ... they rotate in opposite directions! Probably wouldn't have mattered anyway - the ammo was issued from stock manufactured decades earlier and on the first range sessions I needed 11 'pulls' to get the first shot away!! Throwing would have been a good move!

The 'B' annotation is for gearbox fitting, whether ML 7 or Super 7. (That is the thread selection gearbox, not the power x-feed, which is only available on the Super)

Thread: New Nimrods arriving
04/02/2020 23:37:12

"Flogging round the oggin" is a different ball-game from ETOPs point-to-point. The extra reassurance of 4 versus 2 engines was (I would have thought) a useful design function. I assume that the Max debacle means that the P8s don't have LEAP engines so, is it shut one down for patrol loitering or two, both running on low power? As Bill Boeing supposedly replied, when asked why he always flew on 4 engined aircraft, "' Cos we haven't yet made a 6 engine version"!

Thread: Hoist Frame

Colin - the various measurements are:-

Floor to ceiling - 92"

Hook to floor (normal) - 54"

" " (with doubler pulley) - 49"

The boom normal length is 28" and the extension is 40"

The support pole is fitted to the concrete floor and to the roof trusses (6x4) and about 2" from the wall.

I fitted this in my garage/workshop

img_9089.jpg

- presumably similar setup to Clive's (Lidls sourced hoist) and specified length scaffolding pole from Ebay. Worked fine for a (unweighed but too heavy for me to lift) workbench, on the short arm. Haven't used it extended yet.

Thread: Why does everyone disagree with you
27/01/2020 11:44:43

There ARE examples of the OP's views on the forum BUT (as a generality) RARE. ... for which, much thanks!

As a self-admitted cantankerous old git, I try to balance that with a justifiable acceptance that I'm a crap engineer. From that perspective, I accept advice offered here as inevitably superior to my own views ... end of!

Re. fish and chips, here I come into my own ... from a childhood where lack of money (NOT poverty!) meant no shame in asking for the free helpings of batter 'bits' to the over-indulgence of being employed as 'Smokey Joe's' travelling assistant on his Bedford bus mobile chippie. SJ operated from Scorrier (mid Cornwall) and travelled around the local villages, lunch-times and evenings. Small chips 3d, large 6d and fish (always cod) 1/- , newspaper wrapped and cooked (as ALL proper F&C should be!) in dripping! In spite of 'in house' lunches 6 times a week, I never lost my enthusiasm.

There is a danger of the keyboard becoming saliva saturated!

Thread: To bolt or not to bolt
26/01/2020 15:17:19

First point was that the lugs are so close to the sides of the stand that drilling through to position the receiving holes was VERY awkward. Solved that, and the working height problem, courtesy of Lidls and their, caster fitted, 'furniture movers' .

Used four such joined in pairs across each end separated enough to add stability and easy to manoeuvre ,even with my knackered back! Highly recommended!

You have just saved me posting a 'search' query for you ... especially having spent 2and a half hours engrossed in a BBC 4 programme of slow TV!

It was a recorded train and car trip from Auckland to Milford Sound with (praise be!) NO commentary and NO 'background' music!!! Absolutely fascinating, breathtaking scenery joyful watching.

Anyway, the important thing is you are through the worst. Welcome back and take it easy!

Thread: Ally Pally Exhibition
19/01/2020 19:10:49

Super Chammy didn't feature at any of the shows I went to but there were things like Fhrei drill bits, Zyliss vice sets, Clersite spectacle cleaner (brilliant!)., Tridon plastic clamping ties (still made and invaluable for awkward jobs), sets of combined clamps, jeweller's saw table and hold-downs - some still doing useful service. They weren't easily available anywhere else at that time (pre on-line!). Presumably, the cost/reward basis has changed over the last 20 years or so and makes less sense.

Thread: Apologies for raising this again
19/01/2020 14:06:06

From a position of absolute ignoramce, would this suggestion have any merit? I understand that you want to remove redundant teeth, without doing intermittent cuts. Being a non-engineer, I would get my trusty angle grinder with a cutting disc and remove each tooth individually and THEN put the fkywheel in the lathe to clean up. How close to the teeth roots you cut would determine the interrupted cut required.

Someone better qualified will be along shortly with the correct way of doing it.
