Re: [bolger] Polytarp sailmaking for the Fldg Schnr
Leander, the "Dumb Sheaves" that are on my bobcat works fairly well ,,, it
does take a fair amount on strength to pull up the gaff... I epoxied some
brass strips in the sheave for the line to glide across, that did help allot
on the drag,,, the big improvement that I made was to get "good" blocks on
the deck.

Subject: [bolger] Polytarp sailmaking for the Fldg Schnr
> Peter Vanderwaart generously came over for a day of sailmaking for the
Folding Schooner which now has hulls "North Sea Blue" Peter had designed
the sails using the math from Michalak and others. We cut them out of blue
polytarp and put double sided outdoor carpet tape and 3/8 poly three twist
rope around the edges and folded the edge over on the double sided tape.
Peter found some nylon webbing and brought over a sewing
> machine today and sewed on webbing reenforcement at the corners and sewed
in the bolt rope all around the sails. We had a very frustrating morning
with much broken thread and broken needles and crankiness in the sewing
machine and numerous calls for 14 yr old eyes to thread the needle. Went out
in the afternoon to a sewing shop and explained our problem and were sold
heavy duty nylon thread, heavy duty needles and a
> different foot for the sewing machine. Also went to West Marine where they
were having a 20% off sale on line. We had some comic moments trying to
explain to the very helpful clerk, who gave the impression of being a blue
water sailor, what we were rigging. Bought most of what is needed to rig
the FS and saved about $20 but still bought over a $100 of line, all 1/4
stay set dacron except for 3/8 for the sheets. Went back
> to sail making and things went much smoother with no broken needles and no
broken thread. I smelled something like burning plastic during the process,
actually a kind of coal tar smell, and we theorized that the needle becomes
quite hot going through the plastic. All went well and the sails await
finishing and grommeting. They look to me like some pretty deluxe poly sails
with. as far as I can tell by holding them up, a

> I have been looking at these big plastic grommets that I see some places
where the tarps are sold and wonder if any one has experience with these? I
am also wondering what experience others have had with the "dumb sheaves"
that Bolger specifies in the plans, (faired out holes in the truck of the
mast?) I am thinking about perhaps rigging some small blocks in those
places, though the height of the mast should probably be

go to Maine at the end of next week.
