I recently purchased a DoALL bandsaw that had been converted long ago
from a band filer. When the new guides were fitted the upper guides
were mounted upside down. These are the typical guides that are angled
at the ends and when installed make a VEE shaped assembly. The point
of the VEE should be pointing up but these guides instead have the VEE
pointing down. Because of this chips get caught in the valley of the
VEE and are dragged by the saw blade into the tiny gap between the
blade and the guide. The blade is galled because of this. Furthermore,
the guides are only 3/8" thick and the saw takes 3/4" blades. So I am
going to change guides and I don't know which guides would be the
best. I will not be using roller guides. But there are new blade
guides made from different materials available now and I would
appreciate advice on which would be best.
Thanks,

The upper DoAll guides point down, the guides under the table point
up. I've never had the problem you describe with my 16" ML. Chips will
occasionally get jammed between the guide blocks and the backup
bearing cap, but only on the lower guide that lives in a shower of
chips

As far as material for the blocks goes, the DoAll steel blocks are
very hard and wear resistant, and stay true for a long time. I have
reground them, but don't recall offhand what the sparks looked like. I
don't believe they're HSS. D2 would probably be my choice if I were
making them myself. My recollection is a set of 4 was $40-50 from
DoAll, though that was some time ago.
