There has been discussion on pinning bands, so here is a tutorial on how I do it. Not that is the only way but just how I do it, maybe it will be helpful for someone.
First this is the tool that I use to either press or drive the band onto the call and also the 5/8 rod welded onto a pice of railroad iron I use to put the pins in.
Next I use this jig that holds the call in place while drilling. Set the height of the drill so that it nearly goes through 1/16 or so.
After holes are drilled ( I use 2 ) slip the call on the rod and drive the pins down until they just start to bend, then clip the pins off and peen down.
Slip on lathe mandrel and file the peens off.
After they have been filed down.
This is what the inside of the barrel looks like with the end of the pin peened inside the barrel by driving it against the rod. This is why you want to drill nearly through so not to cause a crack by driving it without drilling. This pin will not loosen and come out.
This is the brass pins that I use ( soft ) and drill with a #51 drill bit.
After the call is turned then finish the band as you like.
This is my story anyway.
