Re: [BKARTS] board shear---(loop gauge)

I just checked my shear.  I don't know why your grooves are shaped like a "v".  Mine is shaped like a "U" to fit on the curved top edge/lip.  Mine also has a clearance of about 3/16" at a minimum.  If your shear doesn't have that much clearance try loosening the three large bolts on the bottom of the pan, and see if there is any movement available to slightly alter the angle.  You would probably only need a little, on top of the clearance from the top part.
     Maybe the name loop guage comes from either the large oblong loop that the spring guage rests on, or the little loops that the spring makes on the guage itself, or maybe we should just rename it "the thing guage".
