Don Case Posted June 27, 2021 Share #1 Posted June 27, 2021 I was just doing some measurement on my ship and something is out of line. A little twisted I would call it. I've established a string line at shear level that should be parallel with the keel and as I measure from the frame top to the string I'm finding a gradual increase in difference from side to side. Either the stem or stern post is not plumb or my frames start to lean to one side as you move along the ship or a myriad of other possibilities. I realise that perfection is the aim but is 1/16 to 1/8" unforgiveable? I give that range because with the plans stuck on the building board which is 2 pieces of 3/4" ply glued together 15 years ago (It was flat at one time), I don't know for sure how much of that error is in the ship and how much is my measuring technique. I have no internal stuff glued in so I may be able to pull it straight as I continue to build but I'll have to constantly think about it. thibaultron 1 Quote HMS Discovery 1789 by Don Case - 1:48 - - Build logs for subjects built 1751 - 1800 - Model Ship World™ Link to comment Share on other sites More sharing options...
mtaylor Posted June 27, 2021 Share #2 Posted June 27, 2021 Don, are both ends of the ship supported? If not, sometimes planking will "warp" things a bit. Both ends should be supported until either internal or external planking and beams are installed. druxey and thibaultron 1 1 Quote Mark "The shipwright is slow, but the wood is patient." - me Current Build: Past Builds: La Belle Poule 1765 - French Frigate from ANCRE plans - ON HOLD Triton Cross-Section NRG Hallf Hull Planking Kit HMS Sphinx 1775 - Vanguard Models - 1:64 Non-Ship Model: On hold, maybe forever: CH-53 Sikorsky - 1:48 - Revell - Completed Licorne - 1755 from Hahn Plans (Scratch) Version 2.0 (Abandoned) Link to comment Share on other sites More sharing options...
Don Case Posted June 27, 2021 Author Share #3 Posted June 27, 2021 Yes they are both supported. I'm just going to go check to see how plumb the supports are. thibaultron and mtaylor 2 Quote HMS Discovery 1789 by Don Case - 1:48 - - Build logs for subjects built 1751 - 1800 - Model Ship World™ Link to comment Share on other sites More sharing options...

Don Case Posted June 27, 2021 Author Share #5 Posted June 27, 2021 I checked the verticals about three ways and they check out. I checked it for twist by laying two 4" straight edges across it, one of either end and sighted down them lining up the top of one with the bottom of the other. If there is any twist it can't be more than1/16" in the full 4". So I would say not the board. If I string it from the center of the stem to the center of the stern post the frames midships lean to port almost 1/8". I'm gluing a block on the sheer of the inside of the starboard side. Then I'm going to put a gillpoke from the block to either the keelson or the turn of the bilge of the port side. If I can push it into shape I'll leave the gillpoke in until the last minute. If that doesn't straighten it out at least everything will be twisted. mtaylor and thibaultron 2 Quote HMS Discovery 1789 by Don Case - 1:48 - - Build logs for subjects built 1751 - 1800 - Model Ship World™ Link to comment Share on other sites More sharing options...
Don Case Posted June 27, 2021 Author Share #6 Posted June 27, 2021 The gillpoke is working. Everything lines up to within 1/32" or so. I pushed a little harder than I needed to allow for a little spring back.
