Fitting Roller reefing

Your pdf reader has probably crashed.

I use Chrome. It works OK for other pdfs and always worked on this one before.
Works on the Italian insructions but none of the others
Works on other Plastimo manuals

Another of life's mysteries.
 
Far easier if the bottlescrew is fitted to the sideplates a couple of holes up with a bolt and nyloc nut. You then only have the sideplates to manoeuvre over the stemhead fitting.

That puts all the forestay tension into only the sideplates, which are diminished in width by the holes.
They don't look like as strong as the rest of the forestay, and the distance between them would put a bending load on the bottom pin, not the sheer load its designed for, so I dont think it's supposed to be like that.

That is how it is shown in the instructions surely?

If you look closely at the installation diagrams they show the bottlescrew terminating at several different holes in the sideplates. So I think they actually are designed for that scenario.

Not that I recall when I fitted a 406s it to my first boat. the side plates are there to position the drum height and take the halyard tension, not to take the forestay tension, so the pin had to go through all of it, hence the PITA.

Maybe someone still has the instructions?

Not explicitly stated , in fact very ambiguous.

Take a look at the diagrams on page 13. Clearly shows 2 different clevis pins/bolts in use through the sidestays.
 
From what you say I think you have a rotostay system. It uses it's own genoa halyard and you DO NOT use the one on your boat as it will wrap around the foil. The Rotostay halyard goes up around a spigot wheel which is part of the top swivel assemble, and then comes back down the foil to lock off at the bottom. Instructions, from the Catalac site, follow.

That certainly looks similar but I can see differences.......The foil is more ingeniously interlocking & dos'nt seem to have any screws holding it together.Mine is also made up of two sets of several interlocking parts all several feet length.It also dos'nt have the U bolts at the base which I assume you tie the jib halyard off to once the genoa is hoisted.
That I can see would allow you to hoist the genoa without the tangling at the top once the furling mechanism is used but then you must have the wire halyard running down the side of the foil possibly leading to a nasty contact point/crease in the genoa when furled?

I shall start my own thread when I get closer to the point of assembling my system so as not to bugger up Dylans.Thanks.....

I see what you mean there, but then its only shown that way in the section "measuring the length of the forestay", not assembling or fitting it. The full forestay load would not be met while only measuring, so it wouldn't matter at that time.

Its not made clear at the assembly stages from my brief scan of them.

I never liked my 406s, and have seen so many struggle to fit the bottom pin, so maybe I'm giving it unwarranted bad press. Those plates just don't look fit for the forestay load. If you doubled them between the bottlescrew pin and the deck it would relieve that and make it easier to assemble, but they didn't provide for that.
