I’ve just finished a YouTube video, I’m going to post the link here-
I’m learning all the time… I made a baseplate out of steel and find that it doesn’t seem to work. Seems like it has to be a non-ferrous material- I might try aluminum, although nickel-silver seems to be the standard.
I used Kingwood for the top of each bobbin. This wood is amazing. Relatively easy to work, but very strong. I used Ipe for the middle and base of each bobbin. We have some left from the deck we had put up. It is very plain, not much grain or variation in color, but it is one of the strongest woods around. I read that the original wood planking for Coney Island was Ipe, and it held up for over 25 years.
