I got out the clamping jig I made to do this job 7 or 8 Lee Speed stocks ago. It ensures that I get propper clamping direction with the forestock held securley in the undercut and with the 20 thou shim just behind the tip as I set the tip 20 thou above the forestock top line to allow for triming to suit.
I dont know why it is, but uploading a picture that I have had to rotate to get proper orientation in my album and then onto the forum takes it back to the original orientation so for those ones I have to upload them via my imgur account
