A machined aluminum back plate for a Sterling pump handle. 
With an extra pair of 10-32 holes, this plate is for the tinkers and woodworkers who want to make their own pump handles. Carve a handle, bolt it to this plate, and your pump rod and hammer pickup threads are machined in and ready to use. 
I'll provide a DXF or paper template for the rest of the handle on request. 
Limited stock; raw orders can be machined to order (1-2 weeks) once the initial batch is gone.
