    Sorry going back a bit, I forgot to ask. What is ‘‘Pc’’ ? What does the letters stand for? Sometimes I don't know a English word, I look it up then. But English acronyms and abbreviations are my weak point, please help!

    Regards,
    Angel

    Yes Frank, I thought of many things . . . . ;)

    Personal computer - Political correctness - Pachyonychia congenita - Parsec - Path connected - Phosphatidylcholine - Photonic crystal - Polycarbonate - Propylene carbonate - Posterior commissure - Progressive contextualization - Pubococcygeus muscle - post cibum - Philippine Constabulary - Police Constable - President's Counsel - Principal Consultant - Privy council - Privy councillor - Prime cost - Process control - Professional corporation - Profit centre - Probable cause - Pacific Coast - Panama City - Park City - Pitcairn Islands - Penn Central railroad - Patrol craft - Patrol Coastal - Port Charlotte - Pacific Centre - PC Hooftstraat - Pierre Cardin - Pat Carroll - Palaniappan Chidambaram - Paul Chambers - Phil Collins - Pat Condell - PC (specific type of Mazda C engine) - President's Choice - Production code number - Tandy Pocket Computer - Plaid Cymru - Progressive Canadian Party - Progressive Conservative Association of Alberta - Progressive Conservative Party of Canada - Progressive Conservative Party of Ontario - Porozumienie Centrum - Partido Comunista - Phoenix College - Port Credit Secondary School - Presbyterian College -Providence College - Pembroke College - Physique-Chimie - Port Charlotte High School - Presbyterian Church - Population Connection - Protes'tant Conference - Program committee - Piano concerto - Picture cover - Player character - Playable character - Pocket Change - Peach Circuit - Pokémon Colosseum - Pokémon Crystal - Postcard - Preclear - Public convenience - Program counter - Protective custody - Proto-Celtic - Partly cloudy - Pro-choice - Prontor-Compur - etc.

    Non of them made sence, but I should have know from the context that Pc = Prismatic coefficient wich has Cp as abbreviation.

    Please take this message as humor. I know you meant well! Thanks for the explanation. :)

    Cheers!

    Speaking of dyslexia, anyone ever go to Costa Plenty? Just joking.

    Seriously, though proto-celtic was my favorite pc term, although Port Charlotte is nice, too. It is not Nice, but it is nice.:D

    Anyone who's checked this thread lately probably noticed that progress on my sharpie model has gotten slower and slower, and pretty much ground to a halt in the last week or so. I've been seriously feeling like crap and out of ambition, and not getting much done besides working and sleeping.

    I just figured out why, with a little assist from our family doctor: I have pneumonia. And I haven't helped the situation by continuing to work and lead a normal life, while trying to shake off what I had; I assumed it was just a bad cold or a flu bug.

    The good doctor is stuffing me full of pills half the size of burritos, and dumping weird concoctions down me. Of course he also sent me for chest X-rays, blood tests, stool samples, etc., just to cover himself. He said that when something gets me into his office for the first time in ten years, he's going to take it seriously.:)

    And he's threatening me with a hospital stay, if I don't lie down for three or four days and stop pushing my luck. Hopefully by next week I'll be feeling more ambitious, and start getting things done again.

    Two years ago I had what I thought was a bad cold; after two weeks standard treatment, I went duck hunting with my brother-in-law. Felt worse and worse -- the cold and damp didn't help. Turned out I'd had an upper respiratory infection that went into pneumonia. If I'd taken it more seriously and gone to the doc when two weeks had passed and the cold was still with me, I would not have lost the better part of what would have been a productive month....

    Get well, Troy.

    I still feel like crap. I followed doctor's orders, took my medicine like a good boy, and felt better every day for about four days. Came back to work, and headed straight back downhill again. I'll be finishing up this set of graveyard shifts tonight, and headed home for a week off after I get some sleep tomorrow. So it's back to the doctor, I guess.

    Meanwhile, I did manage to get a little done on the model. Unfortunately, I had to tear out what I've done in the aft end of it and start over; the last time it got bashed up I wasn't careful enough about truing it when I repaired it. The bottom was OK, but the topsides were lopsided and pushed to starboard. So I had to toss the transom and the deck framing behind the cabin, and redo them. That's one of the hazards of building it in disjointed, short chunks of time, I guess. I was more interested in getting something done when I could, than in making sure it was right.

    I wasn't kidding when I said it would take me longer to make the model than to build the actual boat...:(

    But on the bright side, it looks like the deck sheathing isn't going to be as much of a problem as I thought. Between the forward hatch, the cabin and the cockpit, it's broken up into small enough sections that the compound curves shouldn't be more than plywood can handle.

    I'll try to get some pictures up tonight.

    OK, pictures. I have the deck mostly framed in, except for the stern. And I've roughed in the footwell.

    Still a lot to do; hopefully I'll have time to work on it this week while I'm off work.

    There will be lockers each side of the footwell. I didn't have the ambition to build the lids, but since they're flush with the deck you better believe I'll make the real ones watertight when they're dogged down.

    As you can see in the pictures, I went ahead and installed deck beams clear across the footwell. Then I framed under and between them, and cut them out. Working at scale like this, it was the easiest way to hold the shape.

    Some of it's a little rough. I still say that balsa is too fragile and soft for this sort of thing. If I had a shop set up like I did back when I was contracting, I'd have milled my own scale lumber out of sugar pine instead. I probably should've gone to the trouble of dragging out the tools anyway, and setting up in a carport long enough to do it, but I just didn't have the ambition

    But apparently I haven't totally lost my finish carpenter's eye. I eyeballed the bulkheads at either end of the footwell for plumb--and when I cut the ends of the two side pieces square, they slid straight in.:)

    Finally getting around to the transom for the model; I've had temporary ones shoved in from day one. Here's the blank for it. I laminated four layers of balsa, then used a template to shape it. After roughing in the curved face, I put pencil lead on the template and rubbed it on the blank, then sanded the high spots where the pencil lead showed.

    Tomorrow I'll try to get it finished and installed, if I have time between the doctor and trying to fire up my lawn tractor and mow our acre and a half. In Southern California, winter is the green season, when it rains and everything grows like....well, like weeds.:p

    nice job with the shaping
    I know what a pain in the *** it is shaping soft wood through glue lines can be and it looks like you got it pretty fair

    way to go
