Re: [Michalak] Mast varnishing
- Several spars later, I'm a "Spar-B-Q" believer. A pair of thrift-store
roller-blades were sacrificed to the cause. Two wheels still attached to a
bit of the chassis make a roller cradle. Two such cradles clamped to
sawhorses will happily support at least twenty feet of mast. Move them up or
down the mast between coats and the edges feather in without problem. Simple
wooden chucks will grip and turn a variety of differing spar end-shapes.
If you haven't already bought the spar varnish, water based exterior
polyurethanes ("Varathane") dry to the touch in minutes rather than hours,
are tough as nails, durable in all weathers, and retouch easily. The whole
spar can be multi-coat finished in one warm day.
A parting thought; It may be worth remembering that once the mast is
stepped, nobody gets a close look at the top half....
- Place two sawhorses the length of the mast/spar apart. Drive a couple screws or nails part-way, an inch or less apart, on the top of each but near the edge facing the other horse. Drive a long screw or nail into each end of the spar/mast, roughly on its axis. Suspend between the horses. The spar/mast will turn freely as you paint, while the pairs of nails in the horses will keep it from wandering off. After it's dry, remove pivot screws/nails and fill holes (especially the top one).

I haven't tried that--so far I've used "spar urethane" (not
water-based) which takes significantly longer than that to dry.
Will water-based polyurethanes stick to oil-based when it comes time

Nobody gets a close look at the bottom two feet either, which are
under the deck when stepped. ;-)
I considered making a horizontal mast step to hold the mast sideways
by the bottom part, which would then be painted once the visible
portions of the mast were varnished:

The honest answer is " I don't know". It will go on and stay on over stains,
and over epoxy, but I've never tried the oil-based stuff as a basecoat.
