Todays update from Bodgers Lodge

[Gordon WParticipant @gordonw]

I can't stand this sort of thing – Coffee cups dirty and swarf in them!.

[OuBallieParticipant @ouballie]

Neil, Gordon,

You two have obviously never been to the Stevenson Emporium, because it would be impossible to tidy it up.

If, however, it was, JS would be totally lost and never find anything.

Reminds me of the state of my dear Dad's garage and workbench, he knew where everything was, and the marital grief that ensued after Mom dared to tidy up

Geoff – Hence my 'obsession' with organising I think.

[Bob Unitt 1Participant @bobunitt1]

I went there once, best part of 20 years ago – I'll swear that bench looked exactly the same then !

Although I do recall a post of John's on one of the old forums (or possibly a newsgroup) in which he claimed to have discovered something untoward underneath his feet – which was later identified as the very rare object known as a 'workshop floor'…

[Gordon WParticipant @gordonw]

I have the answer- many years ago I went to Leicester, they had a one way system into town, but it was impossible to get out. So some sort of cosmic black-hole is building up there.

Now tidy up the bench

Neil

Cheeky bugger.

That's your cup just dumped there next to the grinder. Why should I take all the flack for your slovenly attitude ?

Answers on the back of a Chester £30 please.

[Neil WyattModerator @neilwyatt]

Fortunately my Dad never used a tea strainer, so I always leave a bit in the bottom to avoid the grouts – works with swarf too

So been a while since the last post. Still been bodging at the old lodge but all of a mutchness, one bent shaft is much like another.

However today i though this looked interesting.

Drive motor out of an older direct drive fork lift truck, these motors which drive a gearbox tend to be quite large units and this motor is around the 40 HP mark. The splines wear bad on these as they are always rocking from forward to reverse. Was toying with the idea of JB weld but not sure if it would hold up ??

Anyway chop it off and bore it out to 1" for 4 and bit inches deep, plus or minus a few microns.

Then grab a lump of EN hardaswitchestits and go hob a new spline on the end. The gear hobber is thinly disguised as a Victorian U2 universal mill with an electronic hobbing attachment that was featured in Issue 108 of MEW by Brian Thompson.

Offered up but not pressed in as a few minutes after this picture was taken it went across the road to the hardening shop, should get this back tomorrow about 10ish and it just needs pressing in with 5 gallon of loctite and drilling for a taper pin.

Whilst the hobber was setup I di two more spare shafts as these are a part that often goes.

If I remember I'll post a finished pic tomorrow.

Nice job, John

It's like a watchmaker's 'pivoting' repair … on a somewhat larger scale !!

[MuzzerParticipant @muzzer]

How does the taper pin work? Is the hole straight or tapered, is the pin hardened? Do you fit it with a Birmingham/Sheffield (Leicester?) Screwdriver or a press? Never fitted one of these myself.

[Cornish JackParticipant @cornishjack]

Absolutely gobsmacked at :-

1. The skill

2. The confidence

3. The 'design' process

4. The result

Any of that extraordinary expertise going spare, please mister?

[Mark CParticipant @markc]

Although it is not mentioned, I suspect there is a through hole somewhere to allow the glue out when it is pressed in (you can squash the air but locktite is not as accommodating!). You also have to work fast when pressing things like this together otherwise the glue sets up before you get it in – or perhaps my glue is a bit past it's shelf life?

Mark

[Neil WyattModerator @neilwyatt]

Hi Mark,

Only John can reveal how he avoids an airlock, but I've been using Truloc high-temperature retainer for a while and it gives you a minute or three to get things aligned, then grips like a limpet.

Neil

[Johnboy25Participant @johnboy25]

Talking about Loctite and the like – I know the manufactures say there is a shelf life attached to this stuff but I've literally had loctite donkeys year that still perform as what is says on the label but am I fooling myself? Has anyone else had this experience of the product?

John

P.S. John – nice job as usual!

[Johnboy25Participant @johnboy25]

Murry… The taper pin fits into a tapered hole – usually knocked in with a Dockyard Screwdriver!

John

[Gordon WParticipant @gordonw]

I have loctite structural and threadlock. I borrowed this from work about 25 years ago. As far as I can tell it still works as intended, certainly the threadlock does.

John,

I mentioned this on another thread, ages ago, but it's worth repeating:

More than 25 years ago, I phoned Loctite at Hemel Hempstead … because we needed to use some "out of shelf life" 638 on a job. [Shelf life was my employer's, not theirs.]

The conversation was basically:

• Is it still liquid?
• Yes
• Then it's O.K …

I still have the remnants of that bottle, and it still does what it should.

[Clive HartlandParticipant @clivehartland94829]

We were advised to keep it in a Fridge if it was only used occasionally. Then again I too have Loctite in the garge where it gets hot and cold and works fine.

Clive

[mick70Participant @mick70]

i have some loctite that's years old and still works fine.

wish my bench was that clean.

spent last day off with my youngest 2 in shop making things.

[mark costello 1Participant @markcostello1]

We were told at a meeting that some Government (USA) agency had to have a shelf life date per regulations. So they started putting it on all products.

[Mark CParticipant @markc]

Most of mine gets used reasonably quickly but some (bearing retainer and such) sits for a long time – this locks up as you might expect (although I don't know if it is a strong a bond as intended) but the "open" time that you have to position stuff seems to get shorter with age. that has been my perceived experience, I don't know about anyone else or other products. I have some "blue" coloured adhesive but I can't think what the number is without looking. This sets up almost instantly after the exclusion of air (which is what it is meant to do) but you have to be quick to get the parts together – if you are too slow it is almost impossible to dismantle again, especially if you can't heat it up!

Mark

PS. The blue glue seems to be much "thicker" these days as well which makes me think it is very slowly curing in the bottle!

[Maurice Cox 1Participant @mauricecox1]

I have a couple of ancient bottles of "Loctite". The older it gets, the more rapidly it seems to go off. The strength does not seem to be impaired, although I have no real way to test this. Many years ago, when "Loctite" was fairly new, our model club had a talk from a "Loctite" representative. He was quite definite that it had a shelf life, and he said that prospective stockists had to have a way to rotate their stock.

The key point of this being that the chemistry of the ageing process is exactly the same as that of the anaerobic setting process.

MichaelG.

[Mark CParticipant @markc]

Maurice, that has been my experience also as mentioned. I also agree about the shelf life aspect, I would not like to think I was sat in an airliner that had critical bits retained by whatever the tech guy could get his hands on!

As for the chemistry involved Michael, was that what the tech guy was actually saying or is that what you inferred from the conversation?

Yes … but it was one man, quite a long time ago.

Edit: This is more recent, and may lend credibility.

P.S. … As a gross oversimplification: The liquid forms cross-bonds, and turns into something approximating Perspex.

[Mark CParticipant @markc]

At 30 quid to read the book it is cheaper (just) to buy a new bottle for critical jobs! But I read the extract and"remain in an uncured stage over a long time when they are exposed to an adequate supply of air" seems to indicate that all our old bottles may well be in a state of partial cure due to a lack of air? The bottles do tend to be very small and the times very long….
