The lump in my hand
Then I tried somethign else; I cut a donut-shaped pad out of a piece of neoprene, and glued it to the inside of my left mine glove. When I tried it out I was happy with the level of padding, but not so much with the glue. It didn't hold and the donut started to move through the glove. Not good!
Then I noticed the washer of a flip-top bottle I had in the kitchen. That's solid rubber, and it's donut-shaped. I tried; it had the right size! I figured maybe I should sew that into a glove. I had no time to do it before I would go underground next. I decided to improvise; I just taped the ring to my hand. That would keep it in place! And it did! We scampered all over the place, and even climbed a few chains and suchlike, which means you use a lot of power with your hands, and my lump didn't seem to notice. Great!
The washer in position. Notice the traces of glue...
My next thought was to perhaps make a contraption with an elastic band around my hand with the washer sewn to it. Maybe that will be better for staying in place. And I could use that in combinaton with any glove, and even without one! And then when the lump grows (it's expected to) I'll take the washer off and replace it with a larger donut.
I found a strip of neoprene and some velcro, and set to work. I added some silicone kit for extra friction. It seems to stay put! It would be nice if I turn out to have managed to make a gadget that reduces the discomfort of the condition to as good as zero. And I think this band does the job fine in everyday activities but wouldn't stay on for hard work like in a mine, but I may well stick to the tape solution for that. I already ordered a few spare washers so I can afford to sometimes lose one. Tape and waskers: simple but effective!
