I had a JK, and nothing was unusual but for the usual iso wrench sizes like 16mm, 18mm, 21mm, etc... May not apply to your vehicle, but I ran into bolts on the front axle with 12-point heads as well....
I have a Microstream USB and like it very much. Mine has two brightness levels controlled with the tailswitch. My one and only gripe is that I understand the battery is a Streamlight proprietary size though, so forget about replacing it with a standard unit.
Yikes! I've never seen a flathead with that steep of an angle. I'm sure the thread is standard, why not bore the jaws out with an 82° countersink and use a typical FHCS?
Impossible. I'm sorry, but I won't pussyfoot around here. If you're looking for a 120V p/s that'll supply a 12V winch operating with any type of load, you're out of luck. Its just not going to happen. Either run it from a car battery with some decent gauge cable, or buy one of the 120VAC...
Agreed. If you ran a neutral out there, just put in a small sub panel and feed a nice dedicated 20 amp 120 outlet, and a 240 outlet for the heater. Also this way, if you ever run into future electrical needs, you're ahead of the game.
No science behind it, but 'd have excellent luck soaking everything (handle, wedge, inside of head) with red loc-tite. I think it soaks into the wood, swelling it a little, then hardens and binds everything up rock solid.
In this weather, I wouldn't worry about water. At least make an attempt to avoid directly spraying where you don't want water to go, but a couple open doors and a fan will have everything dry fairly quick!
I have quite a few of my Grandfathers tools, but this Starrett British made 93C tap handle and the Zubi thumb wrench are my favourites. His name is deeply engraved on both, and I use them regularly.
I'd be modifying the adapter instead of the antique tripod.
If you're capable, build up the inside of the threaded hole with a tig welder, and re-tap for 5/8" fine thread.
If you can't do that, just drill out the hole on the adapter to 11/16", and use a 5/8" washer and fine thread nut to...
Ummmm, grab that with a 10" pipe wrench, don't worry about welding or LH drilling until you break it off below flush lol. There must be a lot of engineers on the boat forums if the "mechanically inclined" members are suggesting you take this to a machine shop! Just out of curiosity, what did...
