Mast raising and lowering, on my Siren

I decided to make my first youtube video to demonstrate how easy and quickly it is to raise or lower a Siren 17 mast. I have been seeing numerous threads and videos of very complicated contraptions and 3 people to do this job. Well here is a video of a past middle aged man doing it solo:)
I probably raised and lowered the mast a half dozen times this morning while trying to get decent footage:)

My Siren 17 getting some love:)

We plan to take the Siren 17 out lake sailing Sunday so today I decided to fix a main sheeting issue that drove me crazy last year. The old block at the cam cleat was corroded and wouldn't move inline with the sheet.
This is the main sheet overview, here is a closeup of the problem. The toggle point, just below the where the line goes thru the block, is seized up hard!
The line rubs against the shoulders of the block, not only here but on the double block on the boom. Also the trail end is tied to a pad loop and crosses over the sheet where it exits the block.

Then when tacking to port a real tangle occurs. I had a couple blocks on hand so after drilling out and manhandling the old block things looked much better.
IIRC a Harken Air Carbo 40mm Swivel
Next I got at the boom end block, turned out it was missing a toggle so the lines again were rubbing on the shoulders of the block.

Not a real good pic but the lines are rubbing. The problem is a missing toggle where the block and carabiner clip.  I didn't have a toggle to fit so I'm using the block off Phoenix until I need it back on the Triton.

Now I have a smooth running main sheet, yeah!  But not done, after supporting a Triathlon tomorrow I'll get back to work hope to get a tiller extension and tiller tamer installed, a real outhaul, reefing point, Cunningham and a symmetrical spinnaker(200sqft off a Flying Scott)! With that and a new Main and Genny sail this boat might actually sail have way decent:)

Getting the Rigging up to spec:)

We got back home a couple weeks ago and have had a chance to get some work done on Phoenix.  First I stripped to old lines off the mast and boom, measured and ready to by replacements. The old lines were washed and retired to support roles around the house or other projects. Next I started checking out the standing rigging and came across an odd setup. There are 3 shrouds on each side, but there are only two chainplates! After much searching on the net I found from the Alberg site that early East Coast Tritons, up to at least hull #192 only had 2 shrouds, hence two chainplates.

The P.O. had simply used a toggle to allow the cap upper/top shroud(not cap as the shroud attaches at the level of the fore stay) and a lower shroud to share the chainplate that is inline with the mast. Not really a good idea and the old silicon-bronze(?) chainplate was worn about the clevis pin hole. Next when I pulled a the bolts on snapped off with very little torque.

So that made me abandon my initial plan to reuse the existing chainplates. Now I have a local machine shop making six new 1"x 3/16"x9.5" SS316L chainplates. I'll install the extra forward of the mast line an distance  equal to the aft chainplate offset.
Hope to have the new plates in hand by next week! I also talked with the machinist about building a tabernacle but he is really busy this time of year so I'll just use a A-frame to hoist the mast into place. The Westsail 32 service manual has a good writeup on using the tabernacle.
