Default WOODEN BANDSAW GUIDE BLOCKS

http://home.mchsi.com/~lawlhote/guid...blockspage.htm

This has obviously been discussed here before. However, I never
tried it. But I've not been thrilled with my present metal guide blocks
for a bit and decided to give wooden guide blocks a try.

The thing is I'm wondering what wood to try. First at any rate.
Quite awhile back I got some hardwood floor samples. They're about
4X4", or a bit larger, and a few are laminated. Nothing really large
enough to make anything out of, but figure I might save a couple of the
imported pieces until I can think of something, maybe trim, inlay,
whatever - like the Brazilian cherry, and Massaranduba. The ipe is
definitely interesting, so I'll groupt it with the ash, red oak, maple,
birch, black walnut, cherry, as potentials. I'll be giving the WD-40 a
shot too.

I won't be doing this immediately, so thought I'd just check if any
of you have tried this, and if so, what type of wood seems to work best
for you. I'll be doing it regardless, but haven't decided yet which
wood to try first.

Hmm, a stray thought just zipped thru my mind - most of those are
just the right size to make a pair of pistol, or revolver, gips. Think
I'll hold back on using the black walnut and maple for this project,
maybe one or two more too. That black walnut, or cherry, would probably
look good on the wondernine.

I have used red oak, white oak and hard maple to make my own wooden cool
blocks. Red Oak is my choice followed by White Oak. Maple did not do well
in use for me. I soak the block with wd-40. Problems I have found are that
the block will scorch, harden and wear a little faster then I would like but
the are easy to refurbish and last as long or longer then cool blocks.

Haven't tried it (my band saw came with roller guides and unless I
want to machine something up there's no retrofit for solid guides
available that fits it that I know of) but my gut reaction would be to
go with ipe. Stuff's infernally dense and hard and doesn't seem to
burn easily like Purpleheart.

Try oak soaked in oil (minwax or the like), wait for the oil to dry
and then harden them up in the oven for about 1/2 hr at 250 - 300.
Mine have lasted quite a few pass/feet.

I made 6 a year or so ago and am still on the first pair.

That's not gonna happen - unless someone gives me some. Don't have
any in the samples, and I stopped buying any wood except plywood or wood
native to NC years back. The only times I work with furrin wood is if
it's free to me. Of course, if you want to send me 50 or 60 board feet
I'll try it. LOL

You don't really want 50-60 board feet of lignum vitae: it's for
projects like mallets--and bandsaw guides. A waxy, waxy, waxy wood
once used for bearings for ship propellors. Rare, endangered,
expensive as all get out now.

Still used for shaft bearings.

Don't know if they still do but CWG Hardwood Outlet used to have short
pieces in stock--4/4 and seldom as long as 2 feet. I have a few of
them that I'm slowly using up.

This from a 'formulae' that was posted on the net. I tried looking it
up again and can't find the article. When I say oven, that means a
old toaster oven in the garage or your inlaws oven - not your oven
where your wife cooks and can kill you for heathen blasphemous
desecration.

According to an aquaintance who's into all things marine, they're still
used for bearings in some ships. Apparently lasts longer than metal in
that application.

It was used in the bearings of the Conowingo Hydro-electic dam which
is about forty miles from my home. I used to ski on the lower
Susquehanna south of the dam. (Now I prefer to ski mountains rather
than wakes...)

Gotta watch out for that shaft rub and beaver squeak in naval
applications. Seriously!

I was going to provide proof but I googled for those terms and ...um... I
gotta go... ;-)

To practice foreplay, one could assume. ;-)

And if you hit Crafts, Woodworking on Ebay you may get the same
surprise I got: there is a LOT of it for sale in turning block and
small spindle size at semi-rational prices.

And I'd lay odds that two-thirds of it is actually an African
blackwood, not genuine lignum vitae.

Still a pretty good choice, dense and hard, but not as self-
lubricating as lignum vitae.

Of course a lot of people oil their blades and thus the guides periodically
anyway.

There are different grades of lignum vitae as well. The stuff the
local supplier has is from Argentina (all his exotic hardwoods are
from Argentina) but it's not the grade used for shaft bearings.

True, but the stress on a bandsaw blade guide is not close to what it
is on a prop shaft. Or, if it is, adjustment is in order.

Depends on your boat. Ever seen the bearings on a paddle steamer?
Lignum vitae staves too, and a _lot_ of radial force.

If you want to see wooden bearings having a hard time, look at the
history of the first Royal Navy destroyers, around 1900 - especially the
first turbine-driven ships with ungeared turbines.
