I recently got ahold of a 1953 12" delta bandsaw ($100.00) and in going over
it I saw that the blocks at the top and bottom guides are a red color. Can
anyone tell me if these are just a phenolic resin or are they cool blocks?
TIA again. Larry
Cool blocks are just basically micarta, far as I can tell. Micarta
comes in many colors.
Can you see layers? squiggley layers. or flat layers?
If the blocks are a phenolic, and many years old, I'd replace them.
Hey, good deal on the saw, anyway!!

True for Micarta, buit not for CoolBlocks.
Coolblocks are similar to Micarta, in that they're layers of fabric in
a polymer matrix. However Cool Blocks are also impregnated with a
lubricant (MS2 ?) which Micarta isn't. This colours their matrix dark
The red blocks that I've seen seemed to be HDPE.
I've not seen plain phenolic blocks, and they'd be more of a brown
than red. I don't doubt they exist, but I think they'd tend to
overheat and char if you ever ran them too tight.
my bandsaw has red phenolic blocks. they appear to be original
equipment on a saw from the 60's and worn but serviceable and no sign
HDPE is IIRC heat formable. doesn't seem like it would be a great
choice for bandsaw blocks....
Cool Blocks replacement. I have been selling Lignum Vitae wood guide blocks
for $5 a set of four for both Grizzly, Jet and Delta bandsaws. This wood is
self lubricating and so dense it won't float. I've sold nearly 100 sets on
