Thanks Matt. I see your point w.r.t. the Spartite - you've got to get the rig tuned before fixing everything in place. I'm using a mast boot and the NGA-18 wedges from Rig-Rite ( http://www.rigrite.com/Spars/SparParts/Mast_wedges.php ), so I have more flexibility. But I still have to get the tuning right before setting the wedges in, and it seems impossible to move the mast butt after it's stepped. This year I'll center it in the box and block it in place, then put the wedges in after tuning.
My mast step support rebuild project is going well but slowly. I put a few more pictures up at https://drive.google.com/open?id=0B-NqAxQ6JxFTSzRLbFo0NDl6U1E , showing the bilge after sanding and painting with neat epoxy, and showing the new GPO-3 supports. I discovered today that I need to go through another iteration of fitting before I can epoxy them in. That's ok, I can be patient. The new forward support is within a millimeter of the original's elevation both port & starboard. But I couldn't twist the new aft support in - I need to trim its "feet" more, to clear those straps of fiber suspending the keel, and then I can assess its fit prior to bonding it in. Have to take a break from all this for a week or so due to real life and the day job - sigh. Cheers, Randy ----- Original Message ----- From: "Matthew L.

The drawing showed a slight rake. It would be easier in a drawing to draw a mast perpendicular to the side view, but the drawing for the 42 shows a slight rake. We surmised that C&C must have had a reason for expending the extraordinary effort of showing a slight rake on a drawing. By doing a little math, we were able to figure out from the drawing what that rake is, which I duplicated in the field. I’m sure it’s not perfect, but I think we got close. The reason it was so important to get it right with the Spartite plug is that once you make one, the mast is pretty much staying there. With wooden blocks at the partners, you can move things around to make adjustments, including adjusting the rake for various conditions if you want. With a Spartite plug, once it’s done it’s done. I also made Spartite chocks in the mast step box, so nothing moves from the deck down. When I’m going through 8-10 footers on Lake Erie, I like it that way. It’s Matt by the way. Hope your project is going well. MLW
