Furniture factories prepare panels, let the glue set, then plane them smooth. I have done the same for hundreds of panel glue ups. If someone damaged knives on a panel with glue squeeze out it is...
The grading rules I am reading are from the National Hardwood Lumber Association grading manual. This organization establishes grading standards for North American hardwood lumber production and...
Sap wood is not a grading defect when grading walnut, or cherry. In fact one is likely to encounter less sap wood in #1 common than FAS. Walnut is in tight supply now. Small logs are being sawed...
Some hide glue facts:
It's a protein and its strength depends on the BIG protein molecules remaining unchanged. Water alone eventually breaks down (hydrolyzes) protein. If the water is basic or...
I don't contribute much here because it is annoying to type a response. As slow as I type the site lags receiving characters and I have to go back and fill in letters, sometimes many in a single...
I have decades of experience building with walnut.
1. For reasons I don't understand linseed oil treated walnut doesn't fade much if any. I have rifles 70 years old that look the same darkness...
Way more important than the speed are the properties of the wheel and technique for avoiding heat. I hollow grind with a 120 grit "pink" wheel. Pink best for hard steel. I use a soft H grade wheel...
For 35 years we sold rough, KD, graded lumber to local cabinet shops. Some tiny shops lacked a planer and we sold the lumber surfaced on the faces to them.
Steel companies provide technical performance data on the steel they sell. Studying these data enable prediction of performance. The A2 dos not retain toughness at high hardness as well a O1. Not...
I have been asked to build one for the local symphony.A search has revealed they range from simple boxes to elaborate affairs withinternal sounding boards coupled to the top. The problem with in...
Every woodworker needs a set of number drills for just such occasions as this one. Surprisingly many woodworkers have never heard of number drills. Splurge and get a set of letter drills too.
You speculation of how the mis-named chip breaker works is incorrect. It works to control tear-out the same way a close set mouth works, namely by restricting the flow of the shaving, which in turn...
The plies were wet when they were assembled into plywood. I checked moisture level on some that was warping as it dried and it was an astonishing 18%!. that is framing lumber moisture content.
From the "horses mouth" on this topic, namely Kato and Kawai who wrote a tutorial on the topic of setting the cap iron for their trade school students...all what Warren said plus when it is set too...
Agree on both points. I use an ax regularly and that is what I have used for decades.
If you have a good edge why grind it off and go back thru all the stones again.

The # 1 rule is that you never grind a good edge away. As you correctly state, once the edge is...
The question was how to identify what alloy it was and that quest did not involve mass spectrometry, nor is it likely any chemist would pursue that route. I didn't need carbon to identify the...
Not mass spec. Analysis is done by nondestructive X-ray fluorescence. Can be done in 30 seconds on any flat surface.
It is not CPM 11V
No firm rule here. I face joint stuff that needs it. All twisted stuff needs it. Some bowed stuff needs it. Certainly not everything needs face jointing. It is hard on jointer knives for the...
As a matter of fact the moisture content is unknown, but at least well on its way to dry enough. Presuming you live somewhere where the house will be heated, and therefore lower humidity, if you get...
When in doubt take it to a motor shop and have someone there provide a safe, authoritive answer to the question. It has worked for me in these situations.
Replacing a tooth is a common repair for any saw shop. I have had it done several times. It costs $3 a the shop I use plus $10 for sharpening. I would expect every large Canadian city to have a...
I spray outside all year. In the winter I have the wood and finish at room temperature. Quick take it outside and shoot the lacquer or conversion varnish. It sure does flow out nice in the winter....
