Chances are you’ll remember that I’m not an enormous advocate of random orbit
sanders. I favor to sand by hand more often than not. I feel
it’s sooner, and it’s for positive safer, particularly on veneer.
If you happen to’re gluing down the veneer your self (possibly utilizing a vacuum
press), the veneer you’re utilizing is normally thick sufficient to
require a great deal of effort to sand by means of. However for those who’re
utilizing veneered plywood or MDF in your venture, odds are the
veneer may be very skinny.
Even on this veneer, it nonetheless takes fairly a little bit of effort to
sand by means of when sanding by hand. However machine instruments like a
random orbital sander can undergo pretty rapidly.
The important factor to do when sanding by means of veneer is to cease
sanding! If the sand-through space is sufficiently small, chances are you’ll be
capable of repair it by portray in among the grain and determine
between coats of end. Small areas are normally pretty simple to
disguise. Massive areas are not possible.
So the query is, “How have you learnt when you might have sanded
by means of?” The reply is that the grain and determine of the wooden
disappear, and the disappearing spot grows bigger.
It’s frequent for individuals to see the spot and suppose they simply want
to sand extra to take away it. The alternative is the case. Sanding
extra makes the issue worse.
Pay attention to this at any time when sanding veneer.
