Cut up the 8mm threaded rod in 8 pieces, half of them 157mm and the others 165mm long. These rods will keep the distance of 92 mm between my motor jig and the saildrive, enough to fit the motor coupling in between. Tried them on the motor jig, and it looked Ok. Then I took the jig down to the boat to see if it would fit on my saildrive?
Well, it did not quite fit. I had to put it much closer to the saildrive to get it into place. At 55mm it worked. But as I will need 92mm I will need to get rid of some aluminium material in the bottom corners...

And they fit on my saildrive :) This week I got my coupling back from the Stockholm splines experts Ingenjörsfima Helfer AB.
Splines specification is: (Kanzaki, SD20 Sail Drive) 20T 30PA 24/48 DP 22.6mm 0.89inch The coupling is bought from Lexar industrial. I choose a 7/8'' L100 3-piece set with the option for one of the hubs to be "blank" (to get splined). This week I got this solar charge controller in the mail - Genasun GV-Boost
This tiny little device promises to charge my 48V battery bank with any input between 5 and 63 volts. I can now be flexible with connecting solar panels depending on needs. I have recently purchased two 100W thin flexible panels (link) that I can connect in series for maximum charge while out and about, or just use one to charge in the harbour during the week. And for topping up the bank during winter I can use my old 30W marine panel. Today I connected one 100W panel through a watt meter and this controller to my battery bank (four 100A AGM) and it seems to work. Watt meter read only 2.5 watts though, guess that snowstorm is not optimal weather... 1. Re-mounted the motor "jig" (6 parts) using sikaflex on surfaces where stainless bolt and spanners touch the aluminium material. This to avoid any galvanic(?) corrosion of the aluminium. (Never use zinc near aluminium...)
Better late than never?
When contacting other enthusiast doing similar projects, I understood that it makes sense to document your project. So here it is, my blog describing my project. Project started a year ago when I ordered a golden motor 5kW electric motor... |
