Shaping with a Router - MetosExpo - Free

Q & A (continued)
cliSCOmfOlt. FOl1unately for most healthy inclividuals, d1ese symptoms
show up well below d1e 0.4 ppm Threshold Limit Value (TIV), and
steps can be taken to ventilate me area before me formaldehyde
vapors become a healm dll-eat. A recent study by d1e Furniture
Industry Research Association has shown mat me formaldehyde
levels in furniture factories and warehouses were below d1e safety
limits and posed no particular hazard to workers in d1e factories.
In your customer's homes where patticleboard cabinets have
been installed, me formaldehyde problem can be minimized by
simply varnishing me exposed surfaces of me particleboard or IDF
wim an alkyd varnish. 111is u'eatment does not eliminate me formaldehyde,
but rad1er slows down d1e emission rate to a level
where normal household ventilation will prevent me build up of
vapors. An alternative would be to use eA1:erior-grade wood products
when building furniture and cabinets. Exterior and waterproof
wood products are manufactured wim a different adhesive system;
d1US, u-apped formaldehyde is avoided. Adclitional information
about formaldehyde in wood products can be obtained from d1e
Hardwood Plywood Manufacturers Association, 1825 Faraday Dr.,
Reston, Va. 22090.

Damping noisy sheet-metal machinery stands
Some of my machines that are on sheet-metal stands don't
have that nice quiet sound like other similar machines I have
seen elsewhere. My machines seem to rumble and boom to a
distracting degree.
-Herbert Weiner, Sarasota, Fl.
Robert Vaughan replies: Assuming all d1e fasteners on me machine
are tight, my first guess is mat d1e macl1ine may not be Sitting
square on me floor. If a shim or two doesn't solve d1e problem,
men I would look at d1e sheet-metal stand. While me machine is
idling, feel d1e sides of me stand and press in on different places to
see if d1ere are any du1.nges in me sound. If you feel one of me
panels vibrating more man d1e omers, put a wood stiffener on it.
To do thiS, cut a couple of 3-in.-wide (or wider) sU-ips of plywood
and coat one side of each with COnSUl.lCtion adhesive. Now squish
d1em in place on d1e inside of me stand wherever me panel was
vibrating (space permitting). Wedge or tape d1e sU-ip in place wim
sticks as necessaty, at1d let d1e adhesive dry for about a day. 111is
ted1l1ique usually does d1e job for me.

Bending dowels
I'd like to know how I can bend a 4-ft. -long, }-in.-dia. dowel
into a U-shaped rod with a 6 in. inside diameter. I plan to
reduce the diameter of the dowel in the middle prior to bending,
as shown in the drawing below. What advice can you
give me on doing the job, and do I need a jig to keep the rod
in
I
shape after bending? -Jim Ward, Denham Springs, La.
