Stop Your <strong>Tools</strong> From Rusting<br />
I moued to Seattle from Denaer,<br />
and the moisture has caused rust<br />
on my jointer and table saw. How do I<br />
stop the rust, and preaent i.ts return?<br />

are very susceptible to rust. But getting<br />
rid of the rust isn't too tough.<br />
Use a sanding block and l8Ggrit<br />
paper or a synthetic steel wool pad to<br />
scrub offthe rust. Tb keep rust from<br />
returning, you can use a product like<br />
Boeshield?9, or BostikTbpCote. Or<br />
use ordinary paste wax. Recoating the<br />
top occasionally will keep rust at bay.<br />
Avoiding Warp<br />
Irn getting ready to build a<br />
table. A woodworker fiend told<br />
me when I glue ap the toP, I should<br />
alternate the orientation ofthe boards.<br />
Anothertold me it down't matter which<br />
way I place the boards. Who's right?<br />

Actually, neither of your<br />
friends is wrong. They're talking<br />
about orienting the boards so the<br />
growth rings visible in the end grain<br />
arc up on one board and down on the<br />
next, or all arc consistently in the<br />
same direction.<br />
If you alternate the boards, your<br />
panel should remain flat across its<br />
overall width, as each board cups in<br />
the opposite direction. But the panel<br />
surface may feel wavy.<br />
On the other hand, if you glueup<br />
the boards with the growth rings all<br />
oriented in the same direction, the<br />
whole panel may cup in one direction.<br />
The surface remains smooth to the<br />
touch, but the entire panel may take<br />
on an arched shape.<br />
I pay attention to the growth ring<br />
patterns, and try to alternate every<br />
other board. But I pay more attention<br />
to each board's face grain appearance.<br />
If I have to, I'll orient adjacent<br />
boards with the growth rings pointing<br />
the same way in order to get the best<br />
looking panel.<br />
Also, make sure you apply an equal<br />
number of finish coats on both sides<br />
of the table top. This helps keep any<br />
moisture absorption or loss equal<br />
on both sides, further reducing the<br />
likelihood of warping or cupping.
