Looper567, I've built 12 of the Kinyon Clones. Also told Ron Kinyon about the tube in a tube ram/guide system he's using on his new one. I build the first prototype hammer years ago from the plans and found the open die space to be the same as a Little Giant (which I already owned) - so my newer prototype air hammers have used this ram tube in a guide tube like I mentioned above and got rid of all the time consuming drilling of brass guides like the plans asks for. I also went to a 2 1/2" cylinder and 3/8 porting on cylinder, valve, hoses, fittings, etc. The 2 1/2" cylinder is also 16 inches long now in my current hammer and I have 9 inches of open die space. I call this "Daylight" to work in and it makes for a much more versatile hammer if your going to take the time to build one. Those are the changes I've made from those plans over many hammers - it works better and is more versatile. I have purposely kept to 3/8 porting - as my goal was to achieve a power treadle hammer, tooling, swaging hammer - not a general forging hammer as I already have a Little Giant and a Nazel - so I don't need power and speed - I needed control and versatility.
