This is a video follow-up from a previous text entry (Episode #71 - Shellac, Can You Make the Cut?) on my blog The Folding Rule. Tag along with me in the shop and you will see that in fact you can “make the cut” and add this fascinating finish to your shop reportaire. This episode covers mixing shellac from dry flakes (1# cut amber shellac) and reducing a premixed cut to a thinner cut (1/2# cut spit coat).
Download a nifty shellac chart for your shop and consider using shellac on your next project.
Be forewarned . . . the only thing more boring than watching someone mix shellac is watching a pot of water boil or perhaps watching your lawn grow!
Coming up in future episodes:
Why you might want to consider getting a hot water pot for your shop and a primer on first-aid for the woodworker.

The following tips are paraphrased from an email by Jeff Scharver, an organic chemist and fellow woodworker.
• Use Zinsser SealCoat as a 1# cut as a wash coat prior to finishing to help prevent blotchiness in cherry and uneven stain/dye absorption in soft woods like fir and poplar.
• Dewaxed Zinsser SealCoat is warranted to have a 3-year shelf life after which it may begin to degrade (chemical jargon is esterification). Zinsser has a proprietary formulation which slows down degradation.
• Plain household aqueous ammonia is perfectly fine for cleaning up syringes, containers, brushes, and wipe on rags. It’s a lot cheaper than denatured alcohol for this step.
