    History Question- Two Tone Hull???

    I've searched a bunch and can't quite find the answer I'm seeking. I have a rescue Hull and in the process of restoring it to operation. I'm fixing all the Hull problems and going to get rid of some spider cracks while I'm at it. Near as I can figure it's a 1989 made by Laser International in...

    Question for an Engineer and Laser Driver

    Wow.....PXR Cam Cleat....now that's slick. I'm totally becoming a Dinosoar. But then you knew that when I eluded that I use AutoCad :-)

    Question for an Engineer and Laser Driver

    Well that's another way to fix the problem I'm looking at. So the channel (side plate spacing) is 7.87mm or .309/.310" which is the Sheave width as well. And the groove is a shallow .5" radius(inch in diameter)?

    Question for an Engineer and Laser Driver

    Thanks Ed........... I think they used 18Ga on the swing arm because the forming around the pivot shaft would be a bitch with 16Ga Do they use a Alum. Micro Cleat or a Carbo? I think I'm getting close to going to Cad

    Question for an Engineer and Laser Driver

    Thanks LaLi.... Both are true. You don't stamp random shapes into the plate, you use them as features. But when you turn a 2 dimensional sheet into a 3 dimensional part, the rigidity increases dramatically. I'm just now seeing pictures of the "New" Allen Vang, that I didn't see before. It'd...

    Question for an Engineer and Laser Driver

    Thank Ed......Yeah the side plates are cold forged to create a box structure to make it stiffer( a superior design feature to the other Vangs) It surprises me that the swing arm is thinner than the side plates, especially with their box structure, though the swing arm is trickier to form and...

    Question for an Engineer and Laser Driver

    Well I always say...Why buy some over priced mass produced kit or some used junk with unknown issues... When you can build a slick custom doo-dad for less. I turn some pretty nice sheaves. I already have sheets of stainless, Delrin rod and stainless hardware up the whazoo. So there you go again...

    Question for an Engineer and Laser Driver

    As in( I thought I splained)....I have a bare Hull, so it's not a working sailboat....just a poorly designed rowboat, at this point. I don't care about fitting it with all spendy OEM parts to stay inside the "rules". Fun, not campaigning (I know many here don't understand that) Harken XD, Holt...

    Question for an Engineer and Laser Driver

    I'm turning a wayward hull in to a working boat(non-class). I'm going to make a BoomVang something like the race versions. Since I have not yet been able to get one in hand.... How thick are the Stainless side plates????? I realize that the design, cross pylons placements and other thing will...

    Hi, I guess this is the PM for you....I have got a hull and am working on restoring it to sailworthy. I was planing on making many parts, but you have lots of stuff listed, I need. If the prices are right and we can ship as a lot, I would take several things off your hands

    Going to Resurrect a Laser

    Hello All, I just acquired a hull which appears to be a ZID circa 1989. Looks to be in good shape except a small spot of delam, near the center of the aft deck. I'm going to try to make it sail again, on a shoestring budget. I have tools and fabrication skills and don't care about class legal. I...
