Hi everyone,
I'm new here and I guess from my Avatar you can see why I stay in the dark. :
I've had a Domino for about 12 months now and thought I'd share my experience with the dreaded tight domino.
The tenons are made of solid timber, compressed along the grooved sides. As such, they react to atmospheric changes like any timber would. (I think they are Euro Beech.) In conditions of high dampness and humidity, they will swell, sometimes by up to 1mm, not necessarily across the entire domino,
but not all dominoes. In this situation, the precision of the joint really shows and dominoes showing any swelling may become hard to insert and even harder to remove, since you are pulling rather than pushing and have the resistance of the workpiece to contend with also. There are three solutions, that I have encountered among seasoned Domino users.
1. Keep the dominoes in an airtight bag in a warm environment between uses.
2. Go through all your dominoes and select the ones which have not swollen, then keep these somewhere for using in dry knockups only.
3. Nuke the dominoes prior to use in a Microwave.
or, move to Arizona ;D.
Option 2 is the one I use.
Regards,
Albert
