Rifle receiver facing mandrel

[tbonesmith]

Hi guys, I made this today to face the receiver face of No4 and No5 rifles when rebarrelling them. I had recently incurred some error in measuring critical dimensions from this plane and hence spent a lot of time chasing my tail. This fixture (outlined in John Hinnants book, The Complete Illustrated Guide to Precision Rifle Barrel Fitting) will allow me to remove imperfections from the receiver face and square it to the receiver body.
