Picked up a nice Bison 1/8-1/2" keyless chuck and now need a JT33-MT3 arbor. Surprised to see Albrecht doesn't make them. I would go with Jacobs but have heard their quality has gone downhill big time lately. Don't know how true that is but would rather go with another name brand...that I can find! I can't find anything but Jacobs and import.
Nice, I also use a Bison chuck for my tailstock but it's a 5/8" cap.
I used to have a Bison arbor on it but I needed to change it recently. I was going to get another Bison arbor but really IMO there's nothing special about them. They aren't even marked Bison or COO either.
I just went with a Jacobs arbor. Like Mikey said NOS are made in England. I needed it the same day, $20 from MSC. I'm assuming China but mine doesn't say on it. My English made ones do say. I'll replace it later with something better but it's been fine so far.
Ajax Tools sells the Bison arbors if interested. They have a listing on ebay.
