Subject : Mixing Resin & Powder

After seeing one in use, I looked for a couple weeks trying to find a kitchen whisk that would fit a cordless drill chuck for mixing urea formaldehyde resin and powder. Found one in kitchen utensils at the local big box Meier store for a buck, the only drawback is that the handle is wrapped with wire and thus somewhat flexible. If I spin the drill at full speed with the whisk in the open air it starts to wobble big time. In resin, or water to clean, it spins very nicely without wobble. The whisk does an excellent job of mixing the resin and powder - almost no tiny clumps of powder whatsoever. Did have to cut the top hanger loop and bend the ends down over the twisted wire handle.

As an alternative, I found yesterday at the local Home Depot a mixing paddle in the paint department and bought one for about $7 to try. It gets the liquid spinning very quickly, but there were some tiny lumps of powder after about 90 seconds of mixing.

If anyone knows of a source for whisks with a solid handle no larger than 3/8" in diameter, I'd appreciate the tip. For now I'll keep using the whisk and try to remember to hold the handle when spinning it in air to dry.

Picture of the two is attached.

I often use a castoff mixing blade from a handheld kitchen mixer. It has a round shaft thus works well in my cordless drill. One can find these for little cost at a local thrift store: Salvation Army, etc. For that matter, I suppose a kitchen mixer would do an even better job, especially for large pots of glue.

I pour the resin and powder into a plastic container and use a paint stirrer or piece of scrap wood in the shop similar in size to a paint strirrer and mix briskly by hand. In about 30 seconds it is all mixed perfectly with no clumps or bubbles. Cheap and effective and will save you lots of trouble with all those gadgets. Also no cleaning, just pitch it when your done. Works perfect every time.

Glad the wood stirrer works for you. I always had beaucoup undissolved bits of powder all over the substrate that I smushed down or picked off so they wouldn't telegraph through the veneer.

Don. I have never had that problem. Is the powder you are using old or clumped together prior to putting it into the resin? Mine seems to be fine and very sifted or clump free. After mixing briskly with a wood stirrer for just seconds I get a beautiful creamy consistency with no lumps. Maybe try some new powder. Funny how the same thing works so entirely different for two different people. Have others had this problem. Scott

I'd considered a hand mixer and even one of the tall skinny electric ones with a "milk shake" blade at the bottom, but I've always been concerned about stirring in air or drying the mix.

Have any of you experienced problems with power mixing?

Thanks.
Larry

I've mixed a number of batches of both Unibond and Pro-Glue now with the hand whisk in a cordless drill and haven't noticed any problems with glue-up or adhesion.

Recently I noticed that some (not all) electric hand mixers have a whisk attachment with a solid shank. After 30 or so batches the coiled hand whisk is starting to unwind in places, but for about $2 each it's still a bargain and a great mixing tool.

Have a good holiday all.
