I keep everything good side up as I’m milling pcs parts. I hate it when I turn a pc upside down and get the chip out, or the bad side to the inside or on the joint instead of a good clean joint.
Face up for everything all the way up to the build.

I always draw up plans for my projects and make calculations, but I really only follow them in the beginning of the project. I feel it gets me started in the right direction and then from there, I measure as I go and design as I go. So my thing is following plans originally, but then letting the rest of the design evolve as I go. This is one reason I don’t like to build from premade plans. I have a hard time following them through to the end.

I measure 5 times before I cut,mainly because the tape measure I’m using(Lufkin) is not very easy to read .

Here are some of my worst fears:
  1. Cutting on the wrong side of the TS blade … one kerf off is always to short/narrow.
  2. Applying glue to the wrong face!
  3. Breaking off a screw deep in a hole because the pilot hole is too small.
  4. Drilling a hole too large/too deep

I watch carefully when I do these operation … very carefully!

I like test fitting everything before glueups. It would be a nightmare to have wet glue on parts that don’t fit.

also
- tearout on a nice big panel.
- forgetting to scrape glue while it’s still soft.
- changing to the dado blade, only to realize you needed the ripping blade first. Arrghh.

Here are some of my issues:

Thinking I have the needed bit or blade and finding after I’ve started that now I need to go purchase it (usually happens at the end of the month and I have to wait to get money to finish the project)

Setting out multiple pieces of wood for a project and at the end realizing I cut the wrong piece and now what I have will not work to finish the project.

Finding a piece of paper or taped that escaped earlier inspection and is now clear coated into the project.

A glue up mistake is not always a permanent issue.

Depending on how large the project and glue up is, a glue up is not always permanent, it can be delaminated, by using a heat gun of 400 degrees or hotter and heating up the glue joint, (no matter how long cured) and using a metal scrapper working it between the glue joints along with heat it can be split apart with no damage to the wood only a little sanding to remove the glue left behind, any wood glue.

One of my peeves is not getting accurate box joints because not having the proper pin or project placement before making the cut.

A big screw-up is when you are setting the dado blade height on a table saw. You crank up the blade to find it is too high, so you crank it down a bit. When you do this, you introduce backlash in the blade elevating mechanism. When you run the saw, vibration will cause the blade to drop down a fraction; you end up with a dado that is not deep enough. This also happens with any blade. Always make final height adjustments while cranking UP, never down. The same goes for routers in a table. If you tilt the blade, make sure you return it to zero right after the cuts are made. I hate it when you cut a piece and find that you forget to zero the blade.

I am a great advocate for precision. My saw is set so that I’m always within .002” of my measurement. I know that kind of accuracy is hard to maintain in wood, but the fact is, the machine is capable of such accuracy and it’s the wood that changes; especially in soft woods. Whatever I’m making, I always make a test cut on scrap before commiting to the actual cut. An inexpensive digital caliper will give you all the precision you will ever need. I do all my woodworking the same as metalworking. Any changes in dimensions due to shrinkage or expansion, are much smaller.
I also draw all my projects with Autocad software. This gives me exact dimensions, eliminating any errors in math.

Planning ahead. Like how to attach cleats on a narrow table or box that will not work with your cordless drill driver.

Not related to wood but I watched my HVAC guys install ducting. They have been doing it for decades yet still installed the returns in front of the supply, causing them to have to reach across the former to install the latter. I just shook my head.

Screw-ups reminds me of a cabinet installer I was working with years ago. We always used 2” screws to attach countertops to bases. This young man grabbed a 2 1/2” and put it through the mica top and well into his palm as he held the top down. He promptly dropped the screw gun and couldn’t remove himself from the top, it became my job to unscrew him and drive to the emergency room.

Ouch ^ that sounds painful.

Here’s one…

Running a stack of parts on the dado blade, and then changing the tablesaw settings… only to realize there was one part that didn’t get cut.

how many times have you burnt an inch for accuracy when measuring the length, then forget to burn it when measuring for the cut?

Or cut the top of the door instead of the bottom?

WayneC the boat was computer generated other wise it would/should still be there! chuckle

I like the fact that his hobby is woodworking and that they show it. There are not enough shows on network TV that show the private life of the characters.

Measuring and re-measuring and re-measuring, and getting not quite right results each time. Then you realize that one side of the hook on your tape measure was bent.

Too buku, too buku.

The first guy I ever worked for used to be a Hell’s Angel. He built a chopper in his kitchen and couldn’t get it out the door when it was all finished – big ape hanger bars and all that, nothing a sledge hammer couldn’t fix.

I’ve done the burning thing too, only in metric.

Cutting drawer bottoms after measuring the inside area of the drawer, forgetting to take the groove or rabbet width into account…DOH!!!
