    Wood paste for mahogany

    Hi all, Has anyone used, or know of, a product to fill cracks in mahogany dimensional lumber? These are not structural cracks. They are a result of neglect and exposure to weather. I will need to varnish over these repairs, so want something that comes close to this wood color. I am in the...

    1984 Chris Craft 21' Scorpion Walkaround

    Does anyone have input, as to good or bad on this model? I am considering a purchase, and would like a little info on this hull design. It is about 300 miles from me, so I can't really go do a look-see until I am a little better armed with some facts. It is an OB hull, w/o power. I have a 2.5...

    bonding to poly resin ??

    When using polyesther laminating resin, is it necessary to scuff up the first (saturation) cured coat before recoating and laminating? I am used to using non-blushing epoxy, and scuffing isn't necessary with it. Also, when using epoxy to bond mat/cloth to cured laminating poly resin, do you have...

    replacing hull coring *pics*

Hull is now supported by the lash up of 2X4s at the transom and a pair of auto jack stands with a 6X6 between at the...

    Fabric overlap?

    I am ready to start laying 1708 fabric on the replaced transom core. The core is 2 plys of 3/4". I plan on 3 layers of the stitched fabric, but am confused about overlap. The West System booklet calls for each successive layer to be shorter than the previous. I was under the impression that each...

    Some help, please, with a balsa wood problem.

    I sure could use some input on a replacement material for saturated and rotten balsa planks. While doing a transom/cockpit deck repair, I noticed some seepage from what I thought was the hull laminate. It turned out that my boat has 1/2", vertical grain, balsa planks, laid fore and aft between...

    Another transom tale **Update**

    My current project boat; 1978 Olympic (Seattle area mfg.) cuddy. I knew there was soft (rotten) wood, I just didn't know how much! It came with a 140hp, in-line 6 and I have a 2.5 liter, 200hp V6 to replace it. Originally, the transom was 2" thick. I am starting over with 2 1/2" goal. Three...
