slot cutter, adjusting depth of cut
I have the Harbor Freight slot cutting set. Like most they have a 5/16th arbor and generate a 1/2" depth of cut. I'd like to make a 1/4" depth of cut.
Unfortunately according to the local bearing supply store, there isn't a 5/16" ID bearing with a 1/2" larger OD.
The QC on the HF cutter is upto their usual standards, on one the bearing slid on/off the shaft (ideal) but the end thread was badly stripped, on the other (that I ended up buying) the bearing is a tight press fit.
A loose fit would be better as I was thinking of just machining some rings on my lathe and pressing onto additional bearings so I could adjust the depth of cut. I was hoping to avoid having to buy additional arbors.
Not sure if there is a better way? I know CMT makes a nice kit where the depth is adjustable but it's over $100 and I'm only going to use this cutter very occasionally.
