One of my brothers has recently invested in a garage full of machine tools to set up his own shop.
I've been talking to him about creating a disk brake conversion for 1-ton and 3/4-ton Stovebolts.
The liability issue has stopped me cold. I don't think designing a conversion would be a big problem, but between the size of the market (I'm sure we could sell six or eight of them) and the liability exposure I think I now know why there isn't a kit available for the bigger trucks.
