Default 289 Otter Tube Threads?
Hey all,
Does anyone know if the threads for the fan switch on a 289 Otter tube are metric, BSW or what they are?
I'm working on mine and can't quite find the correct thread. I don't want to force a tap in it. It did have a broken bolt, which I removed w/o issue and it runs through a 10-24 die but a 10-24 tap seems to want to cut threads.
Anyone have any knowledge of these threads?
Larry
