Although my beams are not quite done, I've been trying to also work on other prep work for attaching the floats. Here is the jig I made for locating the beam bolt holes:
Dry-fitting a part after drilling all of the holes:
So far Fastenal has been my source for all of my 316 hardware. McMaster has quite a bit too I think.
I tried to mount the forward beam plates today but you need three hands to hold all of the different parts in place while trying to get a nut on there. So, I'm going to have to draft my wife into helping soon.
The spacer bushings on the lower folding strut pivot pins are a major pain. I am not sure how tight Ian intended them to be, but the ones I have are so bloody tight that I've practically destroyed one trying to hammer it on, even after putting some light grease on the inside of the spacer. Ordered some replacement tubing, with a wee bit more inside diameter clearance, hopefully goes easier next time.
Have to say, other builders seem to get through these phases a lot quicker than me. Guess I am just slow but oh well :).
