rossd 16 Posted February 16, 2017 Share Posted February 16, 2017 Sometimes a job that should be as simple as hell turns out to be a pain. I have glands for different size cables but none of them are long enough on the thread to go through 12 mm wood, they are for panel steel or something up to 5mm thick so are no use. Shopping on the net the specs say the thickness of wire but no mention material thickness. Could always bore a hole, poke the wire through and squirt some silicone in there but was hoping for something at least a little bit more up market! Quote Link to post Share on other sites
John B 106 Posted February 16, 2017 Share Posted February 16, 2017 Buy a plastic though hull, back fill the tube with as much as you feel you need for a seal. I usually cram some foam or something in and top it off with the sealant du jour. 291 etc. Quote Link to post Share on other sites
Guest 000 Posted February 16, 2017 Share Posted February 16, 2017 If the wiring is visible from both sides ie through a bulkhead then get a couple of stainless penny washers with the hole to suit your wire gauge. Drill a couple of little holes through the washers close to the edge and diametrically opposed to take a couple of small round head screws. Drill a slightly oversized hole through the timber and screw the penny washer to one side. Poke the wire through the washer and timber hole, from the back side apply a squirt of silicone and screw on the other washer. With the washer on each side the silicone is encapsulated and after cleaning up the little bit of filler that's bound to ooze out the finished job doesn't look too bad.

rigger 47 Posted February 16, 2017 Share Posted February 16, 2017 Try getting a spade bit that is oversized for the gland size and drill the thickness of the ply down to suit the gland, - do it on a test piece of ply - suitable for bulkhead Or of multiple wires in on location do an insert - bulkhead again. Or one of the other suggestions. Is the cable going through a water tight bulkhead / deck? Does it need to be sealed? Quote Link to post Share on other sites
rossd 16 Posted February 16, 2017 Author Share Posted February 16, 2017 Its two masthead wires from base of mast into cabin so getting the full force of weather . Quote Link to post Share on other sites
rigger 47 Posted February 16, 2017 Share Posted February 16, 2017 Ok, Cannot remember the boat but it had a goose neck tube close to the mast - cable came down then turned up into the gooseneck. Have seen many leaks with cable glands that were installed vertically - normally when the get old... Quote Link to post Share on other sites

Deep Purple 511 Posted February 17, 2017 Share Posted February 17, 2017 Nah I'd been told of the place and was going there today coincidently Quote Link to post Share on other sites
Deep Purple 511 Posted February 17, 2017 Share Posted February 17, 2017 Went there. They don't have a showroom as such so best to browse their site and turn up with a list. Very helpful though Quote Link to post Share on other sites
rossd 16 Posted February 18, 2017 Author Share Posted February 18, 2017 Gee what a handy place to know for all sorts. Hi-Q Thanks for that. It never came up with internet searchers so for all its cleverness we still have to rely on old fashioned referrals. They appear to have some glands with 18mm thread for 10mm wire so should do the job. The 2 washer trip would look pretty cool but am limited on access on the inside for drilling etc but might use that elsewhere. Quote Link to post Share on other sites
