Chain Stripper Modification

Bent stripper compared to new stripper
Last year I had a guest on board who was trying to be helpful and undertake some of the chores on the boat. He was going through the anchoring process and while anchoring, I (he) found a deficiency in my capstan while easing out chain as one puts on the snubber.
Normally, when bringing in the chain with the capstan, a stripper is in place to ensure the chain comes off the capstan and goes down the Hawse pipe. Otherwise, it can get caught in the gypsy (wildcat in the USA) and wind up the chain around itself. Easing chain out, say when anchoring, the weight of the chain is usually sufficient to take the chain of the capstan gypsy. But in my case, my guest was not aware of the potential issue and as he eased the chain out while holding tension on the snubber line, the chain stayed in the gypsy and bent the chain stripper on the opposing side. You can see the bent stainless stripper above.
Plastic compared to SS
We were in the middle of "nowhere" and there was no way I could straighten that stainless. So what to do? I used one of my wife's "polyplastic" chopping boards and cut it up to make a plastic, but temporary chain stripper. While getting everything ready, including a cardboard template, I decided to design it so it was able to strip the chain whether it was coming in, or going out. I used both hacksaw and Dremel for fashioning the plastic stripper and the thing worked so well, it stayed on for the whole cruising season (6 months). I improved the cardboard cut out a little and had a piece of 6mm stainless laser cut when I went home.
