Regarding your remark about making mistakes, even the master woodworkers describe the many ways you can fix a woodwork blemish, miscalculation, or goof up. When you do the same thing over and over, then you can eliminate mistakes, but then you are into manufacturing or doing a job with a lot of repetition on identical items. If you are doing a one-off, or into creative pursuits, then you are even more likely to make mistakes.

You need to buy some small pan head screws for your duct installation. They also come in handy for electrical work. An overly long screw that extends into the duct is a natural place for a big shaving to hang up, or possibly a piece of something bigger that is accidentally sucked up. Then if you have a bunch of screws in the duct space, you will have a lot of work trying to figure out where it hung up. Since I have spent time finding a blockage in my system, I know what a pain that can be…

Doing the trim on my mobile base for the drill press. Drawers will come later, but I will install the drill press on the on the base once the trim is done since the drawers can be installed with the item already in use.

Staying cold up here, hovering around 1 degree above zero…

Later…

You are quite right on the screws issue. Elsewhere in the system, I cut down the screws. I was making this a quick and dirty video and didn’t spend the time to cut down…

I really proably ought to consider rivets if I want to avoid too much to grab stuff flying past…

I have cut down screws in various situations as well. And although you don’t need a lot of strength in the DC duct, drywall screws, if that is what you are using, are more brittle than most other screws, if I recall correctly. So OK for noncritical use, but not so good, apparently, for most construction purposes. Now, to be honest, I used drywall screws for all kinds of things for years, and never had them fail. So the issue may be over stated, and I suspect it is.

I like small pan head screws for many things, so I have an assortment of #8 and #6 screws pan head screws on hand. Although I guess they are technically for sheet metal and such, they work very well in many situations. I use a short pan head screw to secure my flexible ducting for the DC system to the plastic connectors and blast gates. Then there is no need to cut a screw down. They look better because they lie flush to the surface, and are less likely to catch onto things that brush up against them.

Still cold here in Alaska. Even La Conner WA where our vacation home is located had a dusting of snow. That is the first time in the 6 years we have had the house.
