I've been needing some drill bushings for shop made jigs and see that
the ones from LV are close to $2.70 each and the inserts ar $2.35

if this is a reasonable price? Anyone got a better source? I'm
planning to buy a handful in a bunch of sizes - and I'm also curious
about getting some that are in "odd" diameters like 7 and 11 64ths.

The LV prices seem reasonable. If you need to pinch pennies, you might
consider spending for a 1/2-20 tap and threading the bushings into an
aluminium plate or bar incorporated into your jig, instead of buying the
inserts.

For odd sizes, you (or a machine shop) can bore the holes into steel rod
segments to be glued into your jig.

All good suggestions, all a lot of work. Compared to the time
involved, the LV bushings are a bargain...and relatively precise.

All the more so since bushings should be considered consumables, not
tools, if they're used much. They don't last forever.

I am not familiar with the LV system. I am more into metal working.
Machine tool suppliers[such as MSC and others] stock drill bushings in
all number, letter, and most small[less than 1"] drill sizes. Probably
in metric now. These might work for your odd sizes.
