  1. Thanks for the Thoughts Wyndham, yes my thoughts have followed along the same lines as yours, the two parts I am sure about are the bearing block and the spacer, as for the measurement, I know what I desighned the spacer block around, so I know that measurement is wrong - now. I could have spaced the motor up with washers, but that wouldnt cure the baseplate, so a rebuild is under way. JM, the clearance isnt a lot more on model #1 and even with weed round the prop at beccles she kept going, at the moment it is an option that can be used if the standard prop doesnt give me enough speed without the gearbox.
  2. MM we will be here for you, I will raise a glass tonight when I get home from work and dont have to drive.
  3. I took a punt and ordered a 35mm prop (current one is 30mm) I have tried it on model #1 and its too big, but I have looked at in on model #2, and it looks feasible, so one way or another we will get the extra power. model 2 can have the skeg angled down a fraction to clear the prop - its tight - less than 0.5mm between the blade and the hull, but its doable. I also got a 30mm prop with a fraction bigger blade size, so when I get the motor mount sorted it will be testing time.
  4. Ah but who is defining the actions of whom as damaging, its all in the viewpoint.
  5. with a name like Packman, you expected any less?
  6. In discordance with my previous comment re- Prince Charles I do in fact uphold our monarchy, my comments were made on the basis of the only time i met Charles, where my hand was briefly shaken and he was already moving on to the person next to me, it was so brief that the photographer covering the event missed his shaking hands with me. however given the gorgeous young lady beside me next in line, I can fully understand his lack of interest. That said I do applaud his stance on modern architecture, and the various other good causes he stands for.
  7. is it an American book, as they call rabbet's what we would call rebates
  8. lightbulb moment, I thought I had carefully aligned the motor, I got the manufacturers data sheet with the drawings, and aligned the bearings with the dimensions from these, I had noticed things ran better when pressure was placed on the back of the motor. so time to recheck everything, the coupling was removed and careful measurements taken - yes things were not lining up, I was slightly off on the vertical, but the horizontal, well the bearing was too high, while perfect alignment isnt critical, it helps to be in the ball park, add to that - the brass mounting plate isnt flat, well my materials box has been raided, some aluminium plate has been found, this weekend it will be out to the workshop and on to the precision tooling. yes careful measuring tells me the bearing needs to drop about 1.4mm and align better vertically, I have also found a stiffer brass sheet for the base. version 2 coming up, I have a brass spacer to replace the plastic one I printed (just needs drilling)the brass block will also act as a heat sink to remove the heat from the motor. So I am disappointed I cocked up in the first place, but I am determined to get it right - last time I trust the manufacturers drawing.
  9. Have you looked into future employment as thoroughly as your future living arrangements, generally the two go hand in hand, after all there is no point living close to the boat, if you dont get time to use it. its all about work / life balance, you need a job that you are happy doing, and that allows you the time to get out on the water. Best of luck in all your endeavours.
  10. I have met him, to be honest if there is a younger lady in the room, you will be ignored.
  11. was that a blind on the end window opposite, or were you just lucky.
  12. we have a vaillant at work, running on propane (no mains gas here) that has a filter type of thing on the water pipe - a fernox TF1 Total, I wonder if that was the type of thing you were thinking of, I think its a combined filter / magnet thingie.
  13. longer screws have arrived, now looking at the motor mount plate it is a fraction off alignment, another will be made taking much more care to align everything.
  14. but have you frapped those haliards
  15. and the top quadrant looks like you sat on it - must be why they are also called bucklers.
  16. a b it like the car I met coming the other way down a narrow country lane driving down the middle of the road, then hit the brakes and stopped, there was room for two cars to pass, but half of my lane was down each side of their car, they soon moved over once they spotted I wasnt slowing down though (one does when faced with a volvo.)
  17. Ah, I occasionally get that on some websites (not NBN fortunately) have you tried refreshing the screen. if you press f12 (a section will appear to the right half of your screen) then right click the refresh button top left of the page, you can choose a hard refresh or empty cache and hard refresh - try either of those two.

    Ow

    Here is my idea in a simplified form, you have the mudweight rope over a pulley on a bracket, once the mudweight gets to the top, further pulling results in the bracket swinging back over the boat, neatly depositing said mudweight onto the deck. I have not figured the mechanism to re-deploy it yet. (please note I didnt have any string to make the rope so had to use what I had, but it demonstrates the principle). Using the pulley principle to halve the force required can still be done here. the bracket does have to have room for the mudweight to swing through the centre.
  19. could you give us a screen shot to see what it looks like (either use the snipping tool or prtscrn button) there are two view options at the top right, expanded or condensed for the listing.
  20. surely a good water pistol would have a nice effect on PA speakers (preferably attached to the end of a fire hose)
  21. Tim, if you have such a thing with old ladies in silver cars the solution is simple................ get some red or blue tinted specs, I guarantee that wearing them, you will never be bothered by a silver car again - red cars or blue cars on the other hand - maybe.
  22. here are the bench hooks I made last night, tonight was sorting tools (note no progress on the models as I need some longer than normal m3 screws, these are now in transit, and should arrive tomorrow or wednesday.
  23. when I was younger yorkshire pudding was made in an old saucepan, then a tin of baked beans was heated up and filled in the middle.

    Ow

    I am sure there must be a way of having a bracket that pivots at the bow of the boat, then when the mud weight gets to the bracket, pivots up, swinging the mudweight between its two legs to deposit it on the front of the boat.
