This is a frame blank made so you can design and make a machine to your liking. The bottom plate and saddle are drilled, tapped and proven. The side plate is ready for design, drilling, cutting and finishing. The frame is made of mild steel and you will need some basic but good tools to do the work. The side plate allows for any sound liner or shader geometry. The bottom plate has been left long for a side or bottom style binding post. The frame is made for 1-1/4" coils. We sell many of the parts you would need to finish a complete machine. You can now buy the side plate separately for only $8.00
