Hi all, Someone asked me about this off-list and I was just finishing up the fabrication...a mast gate for my M17. My mast has the cut-away (milled out) mast gate, which makes a big opening, both sides of track. So I made a fixed plate for port side, and a removable plate for starboard (arbitrary, except that I normally am on starboard side of mast when attaching boom and/or mainsail, and I'd heave to on starboard tack if I had to mess with the gate for any reason). They're basically identical, except for the thumbscrews on the removable side. Here's a few pix (not necessarily in order as attached) that show the gate pieces ready to install, the fixed side installed, and both sides installed. Material is salvaged/reused 1/8" aluminum plate. 10-32 for the big screws (gate to mast), 6-32 for the small ones (filler piece to attachment piece). cheers, John -- John Schinnerer - M.A., Whole Systems Design -------------------------------------------- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john@eco-living.net - 510.982.1334 http://eco-living.net http://sociocracyconsulting.com
