  1. Doesn't usually apply to a canal, but if a river shifts by accretion, the legal boundary travels with it.
  2. I have been trying to think of the most unsuitable engine oil and can only come up with two-stroke oil and Castrol R. Can anyone do better? Or worse?
  3. I had a similar issue when the hot and cold feeds to a thermostatic shower valve were reversed.....
  4. The language has crept from commercial operator to commercial transaction via commercial operation. Does that mean the school PTA is a commercial operator because it charges 50p for admission to its Fete? Or an otherwise non-trading charity that pays bank charges? Whilst a charity (or a club) may enter into commercial transactions, it would not usually be called a commercial operator. Registered Charities are required to keep accounts and make them available - but that does not in itself make one a commercial operator
  5. Upload a picture of the switch - or at least set out all its markings. And tell us were it has been pointing. Sounds very much like you have flat batteries - probably due to not charging
  6. Yes - there is a tendency for the bow to rise as more weight is added to the stern. But it is not a simple, balanced rotation like a see-saw or wheel. If it were, the boat would move from horizontal to vertical when a sparrow landed on the bow.
  7. With a see-saw (or your hypothetical boat balanced on a roller) the centre of gravity is higher than the rotation point but essentially it is balanced with (over a limited arc) only a limited weight going over centre from one end of the travel to the other. Hence each kid can push the see saw up with ease - and you might be able to shift the boat. But in the water, the boat does not see-saw about a single point. It is correct that as you lift (or cill) the stern, the bow will descend and eventually sink. However, the weight will not be transferred from one end to the other in full; it's quite complex. As a further thought experiment, put your hand between the cill/underwater obstruction and the underside of the boat - and you will feel some significant, if hypothetical pain quite quickly. Or, if you really want to try an experiment. get in a shallow canal and try lifting the back end by, say 6 inches. If it was nicely balanced at mid length, it will take no effort as the bow drops by the same. You could even change the propeller with your other hand.

    Kawasaki often had double overhead camshafts with bucket and shims atop the valve stems, directly operated by the cams. You needed to check the clearances, remove the camshafts, measure the existing shims and then replace with different shims before before putting back the camshafts -and checking the new clearances. The bike I bought was a poor starter - as some valves were being held open even when cold. So, it wasn't possible to work out the size of the required shims without a couple of tries.
  9. Araldite a nut or (better still) and drilled-and-tapped length of strip metal to the underside.
  10. Some later Reliants used Austin 7 engines which supports the Reliant theory.
  11. I was fortunate to have a trip into the tunnel whilst the repairs were being undertaken in 1983. We climbed into the spoil removing dumper truck at the Blisworth end which reversed at an alarming speed to the the site of the repair. Definitely a good day out.
  12. I've used a half-round (carbon steel) file to smooth out sharp edges. No doubt there are better methods, but it has been sufficient to make the glasses safe to use
  13. Paddle steamers (full size) seemed to have used oscillating engines. But I think many incorporated mechanical valve gear rather than Mamod type timing - so were these double-acting too?
  14. We hired a couple of Freeman 22s in, I think, 1970. There were the Water Gypsy and Water Fairy - but I can't now recall the boatyard. It was downstream of Windsor - but Timms does not sound correct and you say the "Water" was its usual suffix anyway. Any ideas?

    You don't want to break down or overheat on the tideway - but (especially) the depart Limehouse direction means running with the tide so you don't need to push the engine any more than is necessary to maintain good steerage. It needs respect of course - but retain some perspective. It's now close to 50 years since I first made this trip with my Dad; he never used VHF and I only once saw him reach for the 10 shilling, ex Board of Trade life vest.
