One side finished by the end of May, I said.... Ha! I might have missed that deadline by miles but one side is now finished. Well, rough-sanded type of finished: https://boatbuilders.glen-l.com/wp-content/gallery/inboard-zip-by-ian-spring-welwyn-garden-city-uk/first_side_1.JPEG https://boatbuilders....

Good to know. I guess the real reason to go for the 4 over the 2 then is if you have a heavy (or high resistance) boat and you need the extra torque.

Hmmmm, interesting. My Zip is coming on....very slowly. My fault for changing the design and making it difficult for myself. By the time it's done I may be facing similar issues to you in terms of waterways allowing only electric propulsion. I'll have to try to keep my propulsion options open for as...

That's a great looking boat, shandman. I've considered electric power for my Zip too. What sort of cruising speed do you get from the Torqueedo?

The square portion of a carriage bolt is to prevent it from spinning while you tighten the nut. It won't serve any purpose once fitted as the bolt shouldn't move. I'm not familiar with your particular design but on the Zip the carriage bolt heads are recessed below the surface (of the keel or transo...

I am getting zero satisfaction from working on a motorcycle that I'm not going to be allowed to ride for a month or more. I keep looking at the progress everyone's making on their builds and wanting to get back to the boat. So I'm throwing the bike back together tonight, sticking it in the corner, r...

An electric hot air gun (used for paint stripping) works well for releasing bubbles too and is arguably safer around a load of sawdust than a propane torch

The lockdown isn't giving me any more spare time but I have managed to make some progress. Using the Ashcroft method with vertical strips allows the application of inner and outer ply layers simultaneously. There are advantages to this - not having to fair the first layer before applying the second ...

+1 on encapsulating now. Something else worth doing before you attach the frames to the setup members is tapering the tops of the main members down towards where frame 5 1/2 rests. This has to happen before you 'plank' the bottom. I did it after I'd mounted the frames and done the chines and sheers ...

Ambient temperature has a huge effect on speed of cure of epoxy. I have both slow and fast (West) hardeners and use one or the other depending upon the temperature and what I'm working on - whether it's a short or long process. Generally slow hardener in the summer when my garage gets like an oven a...

It's true - chain (or toothed belt, Harley style) off the rear hub would be able to 'correct' the gearing to something more suitable. It would also allow the motor to be mounted more central in the boat rather than offset to one side. Our canals have a 4mph speed limit so a narrowboat (weird canal h...

If I remember the theory correctly it's not the potential for leaks in the connecting pipe that makes it a bad idea. It's the fact that if one tank gets compromised (starts leaking, ingests water, mis-fuelled with diesel etc) and it's linked to the other tank then both are likely compromised and you...

The Vespa motor has peak torque @ 5,000rpm and peak power @ 7,750rpm. By my rough calculations the rear wheel is spinning at around 1,436rpm @ 80mph. The missing information is what the engine speed is @ 80mph - there's no rev counter and the gearing is variable. But most sources reckon it is at or ...

I ride a Vespa GTS300 to work. It's not as powerful as the Beverley (far cooler though 8) ) but otherwise comparable. At full throttle on the open road you're doing around 80mph with the little motor fighting against wind resistance (which is significant at that speed - motorcycles and scooters aren...

Maybe it's the result of prolonged confinement at home driving me slightly crazy but I'm back thinking about a way to make my barrelback Zip something other than outboard powered....and to come up with a solution before my build progresses beyond the point of no return as far as hull construction is...
