How to make tack cloth, sanding sealer and grit size chart


 A forum page I found

How to Make a Tack Cloth
A tack cloth is one of the best ways to remove dust and grit before applying a finish, to make one soak a cheese cloth in water, wring out the water, soak it in turpentine, wring it out again, drip enough clear varnish on the cheesecloth to make it evenly gummy throughout. Store it in a jar with a lid to keep it from drying out.
Gently wipe away dust and fine particles.


How to Make Sanding Sealer Mix one part wood glue with ten parts water, apply with brush, let dry. This will raise the grain, sand smooth.
 
Save Your Sawdust
Before you start to sand a project empty the dust bag, when the bag is full empty it into a clean mustard or ketchup squeeze bottle. You will now have a supply of sawdust to match the project if you need to do the sawdust and glue fill. To do this squeeze some glue in the crack, then spray a bit of sawdust on it and work it in, repeat if necessary, remove excess.
