Our Pretorien has the provision for a wind generator
- the wiring
and the lower mount are already in place. There really is no good place on the mast
for a radar
scanner. We also will need some way to lift
My idea is to start with schedule 80 aluminum
pipe , 1.5" nominal, which fits the lower mount, a hefty stainless one. The schedule 80 is over 1mm thicker than schedule 40, at 5.08mm wall thickness.
The pole would have to be about 12' high, give or take. Wind
gen (air-x with those fancy Portugese blades) goes up high, and then I use some Hollaender fittings to make a platform for the radar
, or get a shop to weld it up. The radar will be a 18-20" scanner, so perhaps 17lbs for the unit + mount weight. It will most likely be a Broadband
radar dome, so no worries about cooking
The Engine lift
is at deck
level more or less, and I can make that up easily with the Hollaender fittings, and some plastic "Slip" rings
My question is, will the schedule 80 pipe, with bracing, be strong enough?
