Mast base

This (part) of the rotating  mast base is one of those maddening little pieces that is difficult to get right, because of all the shallow angles. If you get one bit correct and nicely fitting you then find another bit has gone slightly AWOL! Very frustrating.


It did not take too long to make the individual bits, but fitting it all together and working out 'how' to hold the parts in place for  welding (without loosing the pin alignment for the sheaves) has been quite tricky. The sheaves are running on a 1/2 inch stainless steel rod. I will drill sideways  holes either end of the rod and fit  clevis pins to keep everything in place, and allow for replacement of the sheaves if neccessary in the future


Sheaves fitted and now ready for welding.
