Bean Soup I

If I am not taking pictures or writing it could be that I am depressed, but also there is a cycle in creativity, unless you are a manic artist. It seems sometimes that the extremists are the ones who get anything done. You have to play life like a hockey game, give it your all, then take a restful [...]

Wishing for Sumner

The trouble with the pork chops is that they constituted a new form of substance, very good if you want to go on a diet without pork chops. Not so good for me. I don’t know how these things became tempered like steel, the spanish rice with them should have dissolved some of that iron.

Shrimp Poke Bowl

I enjoyed the last of the stuffed cabbage. The fridge was now bare of leftovers except for bean soup which was in the little freezer. I decided to make a clam florentine soup derived from a shrimp recipe.

Storm and Stuffed Cabbage

Not my clowns, not my circus. That is an amusing phrase, especially now. RFK jr in charge of health. The clowns come in, send in the clowns. It seems to be a recurring theme. If you put clowns in charge of government agencies, then you can take them down. I rant, but government is not a single [...]

Kielbasa Sour Cream

The Thanksgiving Boater's Feast is looming around the corner and I will be involved in vegetable prep again. I forgot what I made last year for the Pot Luck Dinner and went back in the blog and saw it was my ole mole chili dogs. Geoff had made 4 gallons of gumbo and enough rice to feed an army. At [...]

Red and Bleu

The 11 hour drive to St. Marys was punctuated by a couple of traffic jams, the last one occurring right at the exit for Laurel Island Parkway just North of Kingsland where the big submarine base is located. I chose to exit there and avoid the jam, although I would be on local roads for the last few [...]

Proa Design Pt V

27 February 2013 | Bodkin Inlet/Chesapeake Bay
Capn Andy/winter
The recent winter weeks have me occupied reading information about other DIY proa aficionados. Almost all of the boats are self designs, although there are a few designers offering proas. Wharram is one, and mainly offering paddling outrigger canoes that can have a sail added. Gary Dierking has a line of designs that have been well sorted out. There are no proas that fold up like a folding kayak. There are a few skin on frame designs, and my idea that a flat bottomed design was best for skin on frame might not not be true, but I will finish this one before I try something else. Building a non-folding design is very easy. Wharram's outrigger canoes are suggested for the first time builder to get experience prior to building one of the larger designs.
.
The outrigger float that came out too small would have to be replaced and in order to use the Hulls design software to create a new float design, I had to find out why the scale came out wrong. There is a disclaimer that the Hull software doesn't work properly with “some” printers. I tried redesigning and printing. The scale came out wrong and the shape had large wiggles in it. There is a suggestion to use a CAD program, export the design as a DXF file, and print from the CAD program. I had previously used a freeware program from Bentley to view DXF files and it had a print function.
.
First I had to find out why the scale changed or didn't change on the designs from the Hull application. I found that using the rescale function would change some parameters on the drawing page, but the table of offsets in the data section wouldn't change. Perhaps the “lock bulkheads in Z position” effects this change. When I did that and when I drag and dropped the length on the drawing, the table of offsets changed. The file was saved, checking the DXF box in the save menu, and then loaded into the Bentley viewer. The tabloid printer was used and the shapes printed out with no swiggles and the scale measures out correctly. Now the model can be rebuilt with the proper sized outrigger and we can test it when the weather improves.
