scrottieDon't remember where I was with writing about any of this stuff. Biopace via a BCD adapter has been great except 20-30mph winds mean single speed can never have the right gearing. If you're somewhere hilly, you can dial it for going up hills and coast down but unlike going down a hill, the force of the wind when going downwind diminishes with speed. Coasting downwind on a bike just doesn't work as well as it should. This seems like a good application for the two-speed retrodirect design. My knees are not pleased right not. Or a two speed flippable wheel. Because of broken spokes from the soft case and mashing, I was also threatening to try to get my hands on 24" plastic/nylon BMX Tuffwheels for this bike. You can buy disc brake adapters that let you put a rear freewheel wheel on the front, backwards, with the disc bolted to the freewheel, but that leaves me without a plan for either internal gearing or a flip wheel for the back short of going fixed and finding some horrible way to attach a cog to the flip side. I could have and maybe should have just packed the (pretty damn normal) GT in an Amtrak bike box. The S&S bike came about from Maricopa Amtrak stopping doing luggage service and with that, bike boxes, and from breaking two derailers on the red Bioanchi before my feeble brain connected that to the weight of the bike resting on it when the wheel's off. No hanger, no problem. In the short term, I'm likely to drop the gearing on the S&S Salsa even though that would cost me my fun Biopace adpter kludge.
Exhaust is currently not leaking on the Kubota engine thanks to a large square U-bolt pushing the exhaust pipe into the manifold combined with some exhaust gasket goo stuck on dremel sanded metal. This was formerly done badly with some coathanger. I would pay heartily for good biodiesel. This doesn't really hardly use any fuel but what it does use reeks. Eventually the exhaust manifold will have to be replaced. It's already no longer actually water cooled. The electric in-boards look awfully nice.
Oil pressure was at least briefly bodged in to working after stumbling by luck over an article talking about an old Kubota engine problem where an aluminum plug comes out of the end of the camshaft oil galley. I gave up trying to pull the crank pully off with a wheel puller and just took a drill and drilled through the engine block right where the missing cam plug should be and sure enough there it wasn't. I think both of these things were last trip. That got cleaned and then I completely failed to tap threads in to the hardened camshaft's hole so instead I found a bolt as close to just-over as I could and pounded/glued it in with... you guessed it, gasket maker goo.
New mainsheet fiddle block as the other one kept coming apart and did so in the storms probably, and upgraded a size, but that makes it clear that the track it attaches to is also undersized. Weak links are sometimes functionally indistinguishable from safety break-aways. The only thing that kept the boom from swinging wildly was that I'd locked the tail of the mainsheet in a cockpit locker after a previous mainsheet was cut off at cam cleat and stolen. The cockpit locker was effectively holding the mainsheet.
A dock line broke in a way that looks like it was cut well away from any chafe point. I don't think nylon line is supposed to break clean through all at one point away from any turns or chocks. But there was a storm and looking at it, yeah, it should have been fatter. Thankfully someone tied her up again.
Ordered filters of three different kinds.
