Looked at the page. Ouch…
Started in on the bellows patching. I’ve never had luck with liquid electric tape as a patch but this seems to be holding. However, the bellows is a sieve. Holes are tiny, but a bunch of them. Might be able to make them passable for now, using the entire can of liquid. But they need to be replaced. Started looking at materials ($$$), but with the exponential progression in manufacturing quality and general proliferation of Chinese-made bellows available on eBay, it doesn’t make sense for me to make them. Will see how long I can keep the old ones going for now though…
