Here was the mentality behind it because it's apparent that some people have a hard time wrapping they're heads around this one.
If I can find the replacement jaws cheap enough let's say under 20$ it would be worth giving it a shot. The scroll is not in perfect shape either but for a side lathe that I only use to turn big blocks of wood where precision is not required this would work just fine. If the parts are not available or they are to expensive to justify I would trow it away of course. It seems that you have the - o just replace it camp, it can't be done came ( without providing a reason). And my fave Y U ignore good advice. What good advice? Good advice would be hey call so and so because they have it and here is the number and it should cost this much.
Also taig does not make the 4 jaw chuck. They do not sell it. From what I have talk to taig in the past and trust me I talked quite a bit with them that 4 jaw design was made as a way to get around some patent issues with Hightower. I can't remember the exact reason but I know for sure that they only sell the 3 jaw and not the 4. The only ones that sell the 4 are Hightower, Bassel, Tom from my knowledge.
Everyone can take a part and replace it, not many can take a Brocken part and make it like new again- my father.
