Don't Scroll Sleepy
After a recent very short night, followed by a very long day, I decided to get some cutting in before supper. I went through the same old routine, spraying adhesive on the pattern, applying to the chosen material, then adding tape before cutting.
On this particular day, I was trying a new synthetic material and the spray adhesive was giving me a little trouble. I usually get a good tack within a few seconds, but with this new material, the pattern was still slipping when I applied the packing tape.
I fought through the cutting as the tape was holding the pattern in place, until I cut most of it away. After nearly completing the project, I double checked the glue and determined that I had mistakenly grabbed the spray Shellac instead of the spray adhesive. Sometimes great discoveries are made by a misstep along the way, but let me lay any doubt aside, you can't use Shellac for glue.
On a different day, without the excuse of sleep deprivation, I was observing a newly cut bowl which I felt looked pretty decent. I had glued and clamped it with all care, and let it dry over night.
However, when I started the sanding routine, I could hear a crackle and within a few minutes one of the rings came apart. I was a little distressed to say the least. I pulled on each ring, and each ring snapped apart without too much effort. My confidence in my gluing technique was sinking rapidly.
After I started a light sand on the rings, It became apparent that I had not removed the packing tape from the underside of the rings. Let me just say, tape may make a good lubricant, but it creates a lousy glue surface. The bright side is that there will probably come a project that needs a weak bond to use for a temporary hold and this might be a perfect solution to such a situation.
On a few much earlier occasions, when I was first using the Hitachi cw-40, I would frequently bump the power button while changing (and firmly holding) the blades. That will make you wet your pants. Not so dangerous (especially with the soft start) as it was scary. It still happens on my current saw from time to time, but I no longer have to change cloths after those events.
