Hello Carl,
Hello friend how are you so pleased you remember me, I still read your dad's writings sorry shipyards on the back burner for a few months owing to jobs around the house with both daughter and us building home's across the road from each other am now the maintenance man and decorator for both plus lecy for all the Christmas lights, right back to the SD14 like I said I bought some ali square tube like you did but saved a lot of the compressed angle card and never seen it used before in model boating and just wondered if any one else had thought of using it like I wondered or even use it with the ali bonded to it am trying to think out of the box us modellers are often the first to think of doing things another way I know I have pick up lots from others finding new ways to do things,
look forward to your response, use just the Ali like you and your dad did try the card, or use both I have the compress corners which I intended to use for the ballast holds in the in the ships five holds 20, 4lb weights with eyelets enbeded before the lead cooled.
regards Howard.
