Merry Christmas to the group.
A possible cheap and easy fix for this problem: find a local r/c model shop and
ask where the K&S tubing and metal stock is. K & S makes specialty metal stock
for small applications, their brass tubing (both round and square) from the
smallest to the largest size will telescope nearly perfectly diameter to
another. HO gauge model train shops might stock K&S also.
This would be a way of sleeving the 3/8 " id hole down to 1/4".
Just an idea.
73 and merry Xmas to all,

I can't remember who wanted the specail sleeve, but if you still haven't got
one, drop me an email (g3rzp@g3rzp.wanadoo.co.uk) and I'll turn you out a
couple over the holiday. You'll need to let me know what grub screw holes are
required.
Twist drills aren't the best way to get accurate holes that don't wander off
centre. That's why they use the special single flute drills for gun barrels. A
spade drill is good, too, but has its own problems..
