External Mast Tracks

[Ian McColgin]

For a critical spot like that, I've had very good luck using coarse thread machine bolt and tapping the hole in the wood. I then wet it with epoxy, usually with a little injection, and set the bolt. The epoxy hardens the wooden threads. The bond to the bolt itself is not so much that you can't back the bolt out if necessary. I screw down to a firm hand tight - about 7 foot pounds.
