Alan, I know you mean well, but you have inadvertently demeaned, diminished and derogated a reputation I have spent decades perfecting: that of the most tool-less, tool-skill-challenged, chore-unmotivated and lazy-slobbish paddler (if not homo sapien) ever.
Now, now, Glenn. I've heard you make similar claims before and then you went and did a really nice job on repairing that splitting gunwale. If I remember right you even splurged on a clamp for that project. Surely you have a little epoxy left over. No need for a miter box to cut the shaft, I've never used one for that purpose. No need for clamps either but since you have one anyway you could probably find a way to make use of it on this project somehow. As for the heat gun take your van for a 15 mile drive and the exhaust should be pretty hot. Use something to hold the throttle at 2500 RPM (in Park of course) and the gas coming out the tail pipe might just be hot enough. As for lack of fiberglass I don't see why you couldn't cut some strips from an old t-shirt for this purpose. Just needs to be something to fill any gaps and soak up some resin to keep it from all running down the inside of the shaft.
So all you have to buy is the hacksaw and that only costs $6: https://www.amazon.com/Stanley-15-8...474689575&sr=1-1&keywords=mini+hacksaw+handle That's less that the postage to send the paddle back to ZRE.
Or maybe you could even use your folding camp saw. It certainly won't be the cleanest cut but you can sand it smooth with some of that sand paper I know you saved from the gunwale project. Wrapping the shaft with tape before cutting would help keep the cut as clean as possible.
I'll expect to see a 30 minute video detailing the process next week.
I haven't paddled in almost two years now. I could, but don't. Boring story. So . . . I don't post much about my former hobby anymore either.
Well at least that's better than wanting to but not being able to. I hope you've still got a hobby or two that's keeping you entertained. I'm glad to see you back and posting some at least. Place isn't the same without you.
Alan
