EDIT,  Chris Ranney, Tartan Customer Service replied in one day to my web contact question...“T27 Spreaders are 1” OD, 5/8” ID. My T27 #314 only has notches at the spreader end for the upper shroud to run through which I then secure with seizing wire. We have the mast from T27 #295 here at the moment, it appears to have a solid plug welded into the end with a groove machined into it for the shroud.
I can confirm that the upper shroud is designed to be attached to the inboard chainplate. Lowers go outboard. This arrangement allows for a slightly tighter lead on the genoa sheets.”
Initial Post for Type 1 hull...
To those now on the hard...please help me with spreader dimensions where end cap fits in? Both cap shrouds pulled out in a good wind with new sails. And these upper shrouds were pinned to outer chain plates. I’d read the corrections here, but didn’t look at mine.
In Kerr Lake, N Carolina. Learning lots here from many posts. Thanks for your generosity.

Is this what you mean?? Spreader boot?

To those on the hard, or with experience, please help me order spreader tips of the correct diameter. What are Inside and outside dimensions of mainmast spreader where end cap fits in? Any recommendation for end tips for the single spreader sloop? The Rig-rite site has no tubes labeled for Tartan, so I’d love to hear others’ experience.

Both cap shrouds pulled out of spreaders after trying new sails in a good wind. Maybe because rigger pinned upper shrouds to outer chain plates, instead of crossing to the inner plate? I’d read the corrections here, but didn’t look at mine.

Can't answer the question here other than to say that if I rigged someone's
boat and the shrouds immediately pulled free of the spreaders, I'll be
tripping over myself to try to save my reputation and make it right.  And
I haven't heard of the cap shrouds crossing over to attach inboard on the
deck on the T27 or any similar boat of the era.

Was the rig overtightened causing the spreaders to start to bend?

I know little about rigs (read some, actually know little) but either the
spreaders bisect the angle or else they have to withstand the (probably
downward) force.  Attaching the uppers inboard would make the angles
closer, but probably still nowhere near bisected, and slightly reduce
downward pressure, but I don't think it's a solution by itself.

What kinds of boats has your rigger been working on?

Interested in comments here too.  I'm due for this treatment and
have been talking to a fellow.

rickg1952@... posted a while ago with a mast and other hardware
for sale.  He might be willing to check this for you if no one else
has their rig laying in their front yard.  But I'd be suspicious of
anyone else's measurements.  The sail club I cut my teeth on has a
fleet of three Pearson Commanders, and we/they over and over again
kept finding out that beyond the hull, no two were exactly alike.
OTOH, that email may be handy if you do find that your spreaders
are now pointing downwards.

Good luck!

Appreciate the update and info!

Looking through my saved images, mostly from this group, I do see one
example of that on someone else's boat (attached).  I imagine a lot of
riggers looked at that and thought "huh, wonder why they did that",
then promptly changed it.

Not being crossed over didn't immediately or otherwise cause me
problems I know of, fwiw.

And hope you're sorted out and sailing again before long.

This matches my memory of the mast on #328; notches only, wire up, cover with a boot and call it done.

The upward angle of the spreaders (somewhere less than 10 degrees off horizontal) comes from a fitting that goes through the mast and would be 5/8" stock that goes into the spreader tubes.? That 5/8" piece has the proper bends in it and is held in the "upward" position by I can't remember how.

Pretty simple rigging setup mostly.
