Re: Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

Impressive filament for a hobbiest looking for strength. Pretty darn pricey though. Sure. But at 2-3 times the price of ordinary PLA, it isn't exactly exotic. And it is only about 50% more expensive than the Carbon Fiber PETG that was initially used. The problem with these things is the cost of exp...

Here's a better video with testing of Polymaker's Polymide CoPA filament. I get the feeling that Stefan and Justin would get along with each other famously.

Re: Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

I'd make sure that the hygroscopic nature of nylon doesn't bite you when using it on a boat. I'm sure the issue varies depending on the particular nylon blend. Just make sure you investigate/test before going all in. But yeah - nylon is tough so might be good. The big issue with PC is that it tends ...

Re: Motor cover split around freewheel while pedaling.

If you google 9c hub motor and click images you get a bunch of images of motors that look just like mine. This appears to be the same motor sold by many ebay sellers. In theory I should be able to contact any vendor that sells this motor and ask to purchase a replacement cover. That is you best bet...

Re: Farewell Segway

Neat idea, but severely limited by many city’s preventing their use on public areas, sidewalks, or roads. But the principle (and name) is still used on many of the smaller “balance board” type scooters. Perhaps in some areas. But what I saw was the opposite. The Segway was often given privilege ove...

If you take a serious attitude that it's a mobility device and have an even remotely legitimate mobility-related complaint probably up to and maybe including "I can't walk 60 miles in 2 hours" you should be OK with the law. In fact cop brains will mostly think "dumb ass bicyclist, no...

It's a just a ticket. A violation of some obscure regulation or even just some rule and therefore not a violation. Be careful. You need to know and understand the local laws. In AZ you might find yourself facing pretty big fines for driving an unregistered, uninsured vehicle. That could be far wors...

Plenty of jurisdictions DIY is banned altogether.

because they make less money on them. In a way, yes. Developers choose profit margins for all their homes. But since few people want small homes compared to large homes, they can't sell very many and therefore don't make as much money on them. Right. Put another way, they build larger homes because...

The putty has an advantage: it doesn’t shrink in hardening.
Regular JB Weld does not shrink either.

JBweld is good, but not any JBweld. High heat is the one you need. Any other brand of epoxy will do, as long as it is spec high heat. 3M #2214 and JBweld High Heat are best and easy to source. Regular JB Weld has pretty much the same temperature limit - 550 degrees F. It may even be slightly better...

Re: What makes a good commuter?

I'm surprised that you aren't closer to the times I estimated. I guess you probably have more traffic signals and stop signs than I have. I can average about 3.5 minutes per mile pretty easily on a pretty ordinary ebike.

But regardless, I think you'll continue to enjoy the routine. I still do.

True. But so far, Tesla batteries have been lasting 300,000 to 500,000 miles, so not a big difference there.
And may soon be lasting even longer.
