Simple Finish
I have a special, secret, formula for a finish which is easy to use and simple to make. We have to keep this a secret, because I'd like to sell it at some kind of woodturning meeting. (HA!)
There is a simple finish product which you can use on bowls, jars, spindles, etc (not recommended for pens) that you can blend. Just get a quart of white or clear shellac, a quart of boiled lindseed oil and a quart of denatured alcohol. Then go to the dollar store and get a baby's sippy cup with a lid that closes or ketchup squeeze bottles with lids that close.
Now mix the three components in a plastic cup, just use 2 ounces of each one for the first batch. It does have a shelf life. Pour into your dispenser and save your marked cup for the next batch.
To use this product, apply it directly to the wood with a paper towel while it is moving at a slow speed. (If you're a beginner you have to be told now that you never, never, never, ever take a rag to your spinning lathe.) keep the paper towel, which is folded into a pad, moving around the piece. The finish will slowly develop. Here's what's happening.
Shellac, one of the oldest finishes known, which can be put over and under most other finishes, is now sealing the pores of the wood. The denatured alcohol acted as a solvent to break down and loosed the particulates of the shellac. The boiled linseed oil is acting as a lubricant and a top coat for the finish. As you work the pad you are adding shellac, moving it around to be uniform and then sealing and polishing it. Start with something dense like cocobolo sanded to 400 grit. When you finish you won't believe the depth and clarity of the finish. The Bayou Woodturners call this finish "O.B.'s Shine Jiuce" because one our club sage brought this to us years ago and he sticks by this finish on most of his projects. As a joke, we packaged some and put a lable on it that says, "if it was any easier, I'd have to come over and put it on for you." Good luck with finishes. Now you'll have to endure about 99 other opinions on finishes, most will be excellent, read them all and heed them all. The worst thing a woodturner can do is put a bad finish to a good turning.
