Wondering if I can tap into the collective resourcefulness of the crowd. I am looking for what I believe is called a drill bushing. What it essentially is is a piece of steel that is about 3/4" long with a OD of 3/8" with a hole 3/16" in diameter drilled through the center. What I need to do is drill a hole 3/8" and then insert this bushing into the hole and drill a 3/16" hole in the center. The original hole is guided by a block with threaded drill inserts but it sits fairly far back from the start of the hole. The 3/8" bit doesn't wander but the 3/16" one does hence the need for the bushing.
I would have have thought this would be very easy to source but it is turning out to be tough to find. Anyone know where I can find such a creature?
Thanks in advance for your time
