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 />

Bare metal surfaces like your<br />

cast iron saw and jointer tables<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.
