New bandsaw, Old red gum.
Got myself a new 18" bandsaw, and want to cut down some old redgum sleepers. I beleive that the wood is hard to cut ,and someone has suggested a 1" blade with 11/2 tpi.
Would the majority agree with this?
Thanks in advance.
Tony.

Ask Henry Brothers in Sydney, but I believe 1 1/2 tpi with a nice broad blade should be fine.

What 18"BS is it? My BS (bas470 timbecon)will take up to a 38mm, currently running a HB's 1 1/4" 1tpi serlite tipped for resawing... get the biggest blade that'll fit!
Have the sleepers been used by the railways... I wouldnt risk a $100+ blade....................................................................

I got a 1" 1.5 TPI hook Skip in bimetal from Henry Bros. I hav'nt tried it in old redgum but have used it on some wattle logs(green) up to 250mm and it worked well apart from gumming up with the resin .
I've just become an optimist . Iv'e made a 25 year plan -oopps I've had a few birthdays - better make that a 20 year plan

That band from HB should be fine, but make sure you increase your speed. I got one recently and found that running it at a slow speed, it just jammed. Crank up the speed and it'll cut like a laser.

Harry72 has a point, if the timber has been used as old sleepers there may be embedded gravel or other stones, which won't do the (or any) blade much good...
I'm not aware of any manufacturer of a stone detector either

I have recently been cutting old (railway) sleepers into blanks with my band saw.
I find taking to the timber with a wire brush helps get rid of the worst of any grit which may be embeded in the timber.
I also use blade lubricant and feed the redgum though nice and slow.. seems to work fine and I'm just using the crappo blade that came with the saw so as not to risk my nicer blades.

If you do this then:
(1) take it slowly;
(2) check the heat of your motor after each cut; and
(3) check how sharp your blade is after each cut.
This is speaking from experience where I burnt out my 2Hp motor cutting RRG.
Regards,
Mike.

the more expensive the tool, the more the likelihood of them detecting stones, wire, nails etc....

Not just sleepers. I've hit quite large stones and things in the forks of logs up to a hundred or more years old. :confused: Someone put them there when the tree was small and they got grown in. Originally Posted by Auld Bassoon
