Purlins in the Castle
Yesterday, we went up to Napa Valley California to see the new Castello Di Amorosa castle winery. The first thing that caught my attention was the circular tower. After climbing all the stairs to the circular tower I was supprised to see the roof framing purlins. They had used purlins to support the bays between the hip rafters. If I had been asked to cut and stack the circular tower I would have been kicked off the job, becuase I would have stacked it like my Circular Tower Structural Ring Rafter Calculator details. The Castello Di Amorosa castle winery is an authentic version of a Tuscan castle. So to be authentic it used purlins to support the bays instead of rafters.
I guess I need to go back to Joe Bartok's website and lean how to cut the correct angle on the stick just incase I ever get to cut and stack a castle.

NOTE: If your planning a vacation to the Napa Valley for some wine tasting, bring your Visa card, because you can't carry enough cash in your wallet to pay for everything. A typical wine tasting tour cost about $15.00 per winery. The Castello Di Amorosa Castle wine tasting tour cost $30.00. It's worth every penny of it. However, after your done with the castle tour you get to taste the Castello Di Amorosa wines that are unbeliveable. After ten or twelve sips of wine, during your wine tasting, you'll end up saying yes to wife for the $400.00 - $800.00 cost for a case of their wine.
So what's the correct angle on the stick after a bottle of Castello Di Amorosa wine? Was it one bottle ÷ cork height? Or was it...

Re: Purlins in the Castle
We just returned home after almost three weeks on the left coast, hitting spots from SLO up to Whidbey Island, WA.
Best wine tasting territory for us was Paso Robles, CA. We had done everything around Napa and Sonoma and Healdsburg in previous trips.

Re: Purlins in the Castle
Sim,
As coincidence has it, we are going to Napa at the end of this week. That looks like a great place to add to our list of places to go, on our trip. Thanks for the heads up.Tom

Re: Purlins in the Castle
When your wine tasting at Castello Di Amorosa, ask for the reserve wine tasing tour. The reserve wine tasting is from their $65.00 - $100.00 bottles. A $10.00 to $30.00 bottle of wine always has a kick at the end of the sip. When you drink the better wines, like the Castello Di Amorosa reserve, it's really smooth to the last drop.

Re: Purlins in the Castle
Sim, this is exactly what I was suggesting in the Bowed Bay Window Framing Thread ... Post #68. There would be a lot fewer headaches figuring a few compound cuts on the purlins than a bunch of different rafters. And the spacing along the Hip rafters would be a piece of cake.

Re: Purlins in the Castle
LOL ... here's another way of thinking about the angles on the purlins.
We know the plan angles for the Hip roof. The "pitch angles" on the faces of the purlin set perpendicular to the roof are the reciprocals of the main and adjoining roof slopes.
The angle on this face of the purlin (complementary to the saw miter angle) ... geometrically, isn't it in a position similar to the sheathing angle on the face set in the surface of the roof? And the doesn't the blade bevel fulfill the same function as the backing angle?
Try using the sheathing angle and backing angle formulas, but substitute the reciprocal(s) of the roof slope angle(s).
