I have an electronic copies of two sets of instructions for the Reliance jig.
One appears to be the same as that posted by Charles but the other has the operating details in the form of 12 photos with short captions. Same cover page..Only difference I can see in the actual instructions is in the specified drill projection from the front of the trough.
The version Charles posted gives the standard projection as 3 times drill diameter.
The photographic version says “push the drill forward until the centre of the first indent is aligned with the front of the trough”. Which is an obscure description but makes sense when you can see the picture. Basically half a turn of the helical lands. I imagine that for a standard helix drill the effective projection will be the same.
PM me if you’d like a copy of the pictures, it’s a 1.4 Mb jpg so far too large for the forum. Not perfect but easy enough to follow. I’m told it prints OK.
