|Thread: Moore and wright tools|
I know the old Sheffield and UK made Moore and Wright micrometers and metrology tools, were well made. But has anyone any experience of the modern stuff, which i presume are made in Asia ? Are they accurate and hardwearing ?
|Thread: Hoglet Build|
Thanks Jason. maybe a single cylinder engine would be good to do first.
Where are the plans available for this little engine ?
|Thread: Fred Dibnah auction|
A lot of that tat has nothing to do with Fred. Caveat emptor.
|Thread: Maplin Electronics Stores|
Went into maplin in Dublin twice last week and twice i was given the incorrect item by incompetent staff. I wanted a new lnb for my satellite dish. These are usually 40mm in diameter, but my dish takes 37mm for some reason. Anyway the first time i did not know this and bought a "universal" lnb as the spotty youf behind the counter swore it would fit.
Brought it back and met an even more idiotic female, who swapped it for one that "will fit for sure", i asked had she a calipers behind the counter, and she did not know what that was, so i took a chance, which of course did not pay off. To say i dislike maplin is an understatement.
But sadly there are few alternatives.
|Thread: Motorcycle General Discussion|
I got talking to an old boy at the local jumble years ago, it was a hilarious conversation. He like most had reached an age when the aches, pains and other health issues had put him off his classic bikes, so reluctantly he sold them off. After a while and missing motorcycling, he was advised to buy a "modern" royal oilfield single with electric start. All the looks and positives of classic motorcycles, with none of the negatives (ho ho ho).
So he went and bought a brand new out of the dealers showroom Bullet with leccy start. Then the calamity started, The miracle electric start packed up, the clutch fell off the end of the gearbox mainshaft, the wheel bearings went, the steering head bearings went, everything chromed started to rust, the big end went, and when it was replaced, the conrod was found to be bent, and all the aluminium castings took to corrode.
It was like fate was paying a cruel joke on him, the dealers advice was to find a dimly lit stretch of canal and do the honourable thing.
I was looking at both a kawasaki w800 and the new triumph bonneville at the weekend, both well made machines that are reliable.
|Thread: Setting an internal micrometer|
Can you not send it back to the manufacturer for calibration ? Might be the easiest way to do it.
|Thread: Motorcycle General Discussion|
An interesting project Bob. Love to see pictures of that engine. What i did hear about the fury/bandit, being an Edward Turner design, its basically flimsy, and still suffers the old problems, like vertically split crankcases, which are more prone to oil leakage. The man to sort out triumph would have been Doug Hele, but sadly again he got free reign, the money was drying up fast as the japanese took over the market.
I wondered whatever happened to him. He had a place in Yorkshire and was big into making uprated parts for Triumph tiger cubs, a favourite with the pre 65 trials mob. Glad its working out well for him.
Yes, bad management and greedy investors, never any profits set aside for reinvestment. Some of the machinery sold off during the closure of the Meriden factory in the early 1980's, was pre-war manufactured ! Unthinkable in this day and age, i believe in the new triumph factory, all the machinery is replaced every three years, regardless of condition.
I was reading about the infamous Nora the other day, presenting the bsa/triumph board with outrageous bills for her latest fur coats and other outfits. She reckoned that she was justified, because she appeared on show stands bedecked in her finery, i can just imagine the faces of the ton-up boys standing there looking at her draped over a bike.
I am building a 90 degree triumph engine at the moment. It can be done using the stronger norton commando crankshaft, which i am sure you know, has two throws bolted to a central flywheel. A relatively simple task of making a new flywheel, turning the timing side mainshaft to triumph dimensions.
Camshafts are available for the rephased crank, as are conrods to suit the norton crank in the triumph cases.
With a big bore kit the capacity ends up a little over 800cc. A toolmaker chap i know in Australia has done several of these conversions, and reports that even without dynamic balancing, the 90 degree engine is noticeably smoother than the smaller capacity 360 degree engine.
So Phil Irving and his theories were vindicated, and as Hinkley triumph twins are this configuration now, it appears to be the way to go.
The time for meriden to completely revamp the engines was when they switched from pre-unit to unit construction. They stuck with the same cylinder spacing and 360 degree crankshaft. Instead of going wider and allowing larger bores, and they should have went with a 76, or 90 degree crank, it would have been easy to enlarge the engine and still have it vibrate less.
That all alloy engine was one of the best looking motorcycle engines ever made. I have the makings of a triton here, but have to finish rebuilding my old a10 golden flash first.
|Thread: Sine Protractor|
Looks a clever idea Steward, simple, but then the best ideas are often the simplest.
|Thread: Tom Senior M1 suds belt|
If you wait til monday, i will pull the belt off my machine and measure it.
|Thread: Recommendations for a quality milling vice?|
Abwood are good, but i think they are an old brand. I have one on my Tom Senior, its a nice size, but the problem with buying an old one is the wear it might have suffered. Rohm i do not like at all, any of their tool i used professionally, were bad quality, people get fooled by equating "made in Germany" to quality.
One problem i notice with small milling vices, is few make appropriately sized parallels for them.
|Thread: John Stevenson|
Just stumbled across this thread as i only drop in here occasionally, but what terribly sad news to be greeted with. Sadly people like John are a dying breed, down to earth, knowledgable and helpful. Rest in peace to the man and condolences to his family.
