Ben's post on his new windex reminded me of my solution, so I thought I would share it here.

Last spring I tried to remove some old parts from the masthead only to find the stainless steel screws completely welded to the aluminum masthead by electrolisis. I ended up breaking the masthead while trying to remove some of the screws and ended up ordering another masthead from Catalina Direct.

I decided I needed a better way to mount my wind instruments transducer, my windex, anchor light, and vhf antenna to the masthead and came up with the solution below. I left enough space for two screws to come through the side of the cover which I mount the anchor light on, and there is about 3/4" gap above the top of the masthead for mounting the antenna, windex, and transducer. The cover is held in place on the masthead by the existing clevis pins.

I can now remove all of my "stuff" just by pulling out the clevis pins (with the mast down of course) and storing the aluminum cover with all the garb attached.

i struggled about two days trying to figure something out.

what thickness did you use?
did you have this fabricated in a shop?
where did you find the material?

Nice job on the engineering drawing, it looks eerily simlar to my drawing of my masthead crane I just fabricated, although I used stainless steel sheet metal.

If you made this out of SS and had a SS bow eye(U-bolt) welded to the top, you would have a nice looking masthead crane.

Dave,

I had a sheet metal shop make it for me. Cost $12. One mistake I made was not having the shop drill the holes for the clevis pins. If I was to do it again, I would mark on the drawings where the holes go and let the shop drill them.

I had mine done in aluminum, but I like Don Lucier's idea of doing it in stainless and welding the eye to the top for additional use as a masthead crane.

Another improvment I would do:
rather than leaving a small gap to accomodate the heads of the screws between the side of the masthead and the cover, I would make it flush and have stud-type recessed bolts pressed flush into the side from the inside of the cover, then just mount the anchor light tube to those to bolts.

Brian.
