Todays update from Bodgers Lodge

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

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.

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....

Quite so, Mark

That's essentially what those three bullet points were getting at.

MichaelG.

Dunno how true but I was told that when it was invented it had a very short life as any sealed container allowed it to go off. Apparently the container it's now stored in is permeable and allows air in but not the product to leak.

Like many of you i have stuff in bottles from last century but the day to day stuff is relatively fresh because I use so much of it.

Keep it in the fridge

Good advice, you have to allow for JS running his workshop at 40C

Neil

40C? That's 104 degF in real money. In most ships engine rooms I sailed in that was quite a cool engineroom temp, but we didn't bodge stuff like wot Mr. Stevenson does every day, far too technical, just kept the job running was the game. How can he work like that in that temp on technical stuff - us lot would be constantly leaking everywhere.

I'm told he works in just a pair of Speedos

Yuk!

At least it's not a mankini.

Neil

Even so............. got my sanity to think about, that idea is not doing my thinking any good, therefore sanity not good either......

Chris

Heretics, it doesn't get that hot all over, still have some dark damp corners.

I worry about the French, the last campsite I stayed at insisted you wear speedos to use the swimming pool, bald overweight men in speedos it not the best image, luckily I can't see myself so it's not my problem.

Mike

Why would they insist on speedo's? Inquiring minds and all.........Also found a place to stay away from. Order eye bleach if going there!

Yes ....... but bet they are HOT dark damp corners, nothing in the post said anything about cool corners.

The French do seem to have a thing about speedo's - found this in Brittany too. Think it's something to do with the short and curlies. Not my problem either, not bald but way overweight, but likewise can't see myself so no worrys.

Chris

Semi interesting one in that we have some bike guys on this board.

Now the Germans have a reputation of engineering, personally I think most of their stuff is over engineered and fussy.

BMW in their infinite wisdom of the twin cylinder boxer engine machine a thread on the alloy cylinder heads for the exhaust nut to screw on and secure the pipe, pretty common but what isn't is they then screw an alloy exhaust nut onto this thread.

Few miles down the road and all comes loose, tighten up and it's all OK, until you come to strip down and it welded itself to the head. The smart mechanics know this and split the nut, clean the thread up and fit a new nut. However if it's been shuffling are the guy doing the job isn't familiar with the self breeding habits of alloy on alloy it rips the thread up on the head. Only way round this according to BMW is to fit a new head.

Well being told there is only one way to do a job is a mortal challenge..........so set the head up on the mill, opposite hand boring bar fitted to the boring head and waz the thread off with a bit of the spigot.

Just started the job on Monday when remembered to get a picture, not that clear but it does have about 1/2 a thread, a bit ripped up on the spigot.

So thread off and reduce the spigot down from 52mm to 46 using the old formulae "If it looks right"

So now had to leave it as when I checked up I'd no bronze in stock so ordered some Monday dinnertime.

Bronze came today from Leeds Bronze [ no connection other than a customer ] and they have a £30 minimum order now but that's not too bad as bronze is expensive. Ordered 12" and it had to be charged out at £30 minimum but if I had 15" it was still £30, so we had 15" which is fantastic value seeing as many on-line metal suppliers charge from £15 to £25 PER INCH.

This is what £30 worth of bronze looks like.

That's cored bronze BTW 58mm OD and 40mm ID.

Turn it down to 52mm and belt a length of 2mm pitch thread on so got some future spares and these are always ongoing.

Part a slice off and bore out and now got a ring ready to be wormed up and shrunk and pressed on.

Then belt and braces, drill 4.2 mm and tap 'nearly' thru with M5 tap. Screws two brass screws in, cut off and clean up with a thread file to pin the sleeve.

Just possible to see one of the screws where the felt tip blob is, other one still not cut off but basically job finished.

Another happy camper.

I'm with you John, as when I'm told I cannot, or only this way, I just naturally rebel and stick a finger or two up, and look at other ways.

That's a bl@@dy good price for the bronze! I got shafted for the small length I bought to make the TS Overarm bearing
