Im not sure what you mean ???
When you mentioned the phrase "cutting the mast" you got my attention. I have an O'Day Javelin, 1973 vintage, which one of the previous owners bought and installed the tabernacle kit. Whoever did the job of installation didn't "measure twice, cut once." The mast was cut at a curved angle, and he tried to compensate by hammering or otherwise bending the aluminum so both the tabernacle fittings would fit. The result was that the two screws on the mast eventually created enlarged holes presumably due to stress. He then trimmed a bit more off the mast to make it square resulting in a short mast which left the shrouds and forestay with entirely too much slack even with full turnbuckle. I had to cut another 2" off the mast and then fit a shim between the mast tabernacle plate and the "into-the-mast" fitting. The shim was simply a piece of hard wood, sculpted on a band saw to resemble the shape of the mast, finished, and drilled to accept the two bolts through the tabernacle (A real "duct-tape" kinda job, but it works.) Good luck.
