white metaling old conrods

thought id do a little write up on this as it is a dying art .
for those not up on white metalling rods its basically from pre 50s in motorbike terms , my tiger 100 is 51 (first of the all alloy motors)and instead of big end shells it has a durillium (hindium) rod machined to the journal and a steel con rod cap bolted underneath .the space between the cap and journal is taken up with white metal which is poured in and bored out to spec .
it was all well and good while it was common but these days its very rare to find anyone doing it .
first off is removing the old white metal

the caps must be leaded next to get the metal to stick
hopefully the pic attached
next is making the little jig to hold the caps together for pouring .



back in a bit

Re: white metaling old conrods

so after the jig is made up you have to seal the caps in with fire clay and strips of aluminium so the white metal doesnt pour out .its expensive stuff loike!
then you heat the metal and also the jig/rod caps , when the temperature is right you pour the metal in and poke it a bit to get air out .
after that it get let cool while you have tea .

Re: white metaling old conrods

tea was lovely :-) . after a bit of cleaning up the cap is bolted back onto the rod and its set up in the rod machine to get bored out to the right size to suit the crank journal . very time consuming stuff indeed.

poxy pics keep fuckin up.ill fix this later.grrrr

Re: white metaling old conrods

Fair play chopper, its nearly a lost art, knew a guy in engerland used to do it for prewar unmentionables, twas a common job one time but like evrything else its being forgotten about in this age of disposability, if you offered that service through the vintage clubs id say you get a bit of business out of it.
Great to see someone learning the older skills tho, ffs theres lads n here never even seen a set of points never mind know how to set em,

well its for some of a bike .its for my triton project .its a 1951 tiger 100 engine (pre unit) , the first of the all alloy engines .it used to be raced on dope .it has the r followers and race cams . the motor was fairly rough but its getting there .its a labour of love . i have a slimline featherbed frame to put it into but not much else at the mo .
too many projects and too many kids means progress is slow

I doubt it as I can`t think of one vintage motor cycle with ``white metal```bearings, you need a high pressure oil system for plain bearings which was not a vintage strong point. Roller bigends can run on very little oil at no pressure.

It phased out in the early 50s really but theres a lot of old bikes like the triumphs were done like this . You can convert them to shells although its expensive .its still big in the old cages world though .rollers and the like .mega bucks to do them .I done mine msinly to learn a dying skill . Theres only one lad I know of in ireland that does them and he is not in great health .while I was there a guy came from uk to collect his RR crank and rods.

Re: white metaling old conrods

My first job as an apprentice when I left school was with a civil engineering company. I started in the small plant department (water pumps, generators, etc.), and the old guy I was working with had a load of old stationary engines with hinged crankcases. They were hinged because the bearings would need to be re-metaled on a regular basis, and the first 'job' I had after starting was to get the engineer's blue and a scraper, and re-metal the crankcase bearings on these old engines. It didn't matter that the engines were old relics and no longer in use. The old boy I was working with wanted to teach me engineering, and as much as I hated doing it, as it was completely obsolete, it made me realise how different things were back then, and how times have changed. This old guy used to spend his days listening to engines, waiting for the signs that the engine needed a rebuild, which wasn't years, it was usually just weeks, or, if you were lucky, a couple of months since its last rebuild. How times have changed!
I served my time with this old guy, and he was proper old-school. It's a shame to see that generation go.

Re: white metaling old conrods

Akshally... Seeing as I'm a bit pissed (for a change)... I'll reminisce a little further.
This old guy was called Ernie. He had a nose that looked like a pear, so he was known as pear nose. He was past retirement age when I started working there. I think he was about 72 years old, or thereabouts, and still used to cycle 15 miles to work each morning, and 15 miles home. Fuck me, imagine asking that of a young lad these days! You'd be up in court for child abuse!
Anyhoo, I digress... I was sat eating dinner (lunch, for modern posh cunts) with him one Saturday afternoon, and we got onto the subject of 'the war'. He fought in WWII, and didn't really like to talk about it, but I asked him what it was like, how bad was it, was it as bad as people say? He said... Nah, it wasn't as bad as people say. People have no idea how bad it was. It was far worse than people say. I asked him what did he mean, and could he give me an insight into what actually happened. I was a young kid at the time. Maybe 17 years old, and unshockable... or so I thought...
He said, OK, we'd raid a town, kill all the men and rape all the women. Then probably get pissed and kill most of the women...
It was blatantly obvious that he was remorseful for what he'd done, as he was in tears as he told me, but he started out so matter-of-fact, that it was quite obviously the norm, and it wasn't until he was regurgitating what happened that he realised what he was saying, and I saw the look change on his face, from one of those reminiscing smiles to a wry smile, then to a look of complete sadness, as he relived his times.
I never encroached on the subject again, as it obviously wasn't something he was comfortable with, but, nonetheless, I think he wanted to tell someone, just like my grandfather, in his last days, felt the need to tell me about the black and tans he'd buried in the bogs ,and about the priest (a second cousin twice removed to the power of three of mine) who brought him to a bog in Donamon, to kill a lad who wouldn't marry the girl he got pregnant. My grandfather wept as he relived the time he had to cut off a young lad's head with a slash hook, because the priest told him he had to do it.
