« Part 89: Narrow wall drywall patching, and dust collection update... Part 90 of Workshop Development series Part 91: Fixing mistakes, filling in the blanks.. »

For the quick link to the long version of the story, here go you…

I ended up with a forehead slapping stupid mistake this weekend. I had the measurements correct on paper, and I KNEW what it was supposed to be. I was LOOKING at them just prior to setting up my stops, and went ahead and set the stops wrong, and built the whole shebang wrong anyway!

I measured heck, 3 or 4 times, I just deserve a what were you thinking you moron moment!

I need to re-measure, but I think it needed to be 20 or 24” deep. Somehow I managed to build it 16… Dummy

I learned a long time ago to not shy away from my mistakes. They are what help me learn and move on, but this was just, well I don’t know. I have a sneaking suspicion that I should not have been using power tools… I just don’t think my brain was fully engaged…

Well it seemed right at the time.

Due to limited materials (my truck is broke, so I can’t get fresh sheet goods yet…) I figure I will…

#1. Extend the top using scrap ply segments cut to width, left a little long on each side, aligned with the sides to be trimmed in the middle. Make the connection with either biscuits and glue, or pocket screws. I have lots of both… #2. Hope like crazy the glue got sucked up into the wood instead of holding the joint so I can disassemble the joints at the side frames. If I have to, I will cut the back free of the side frames with my flush trim saw, and just start over again on the side frames. The other option is to simply extend the side frames with biscuit or screwed extension pieces. Perhaps braced, That would likely be the easiest route, and I want this done yesterday pretty much… #3. Trim out the arc on the top extensions. #4. Remove the silicone caulk sealing the curved panel to the top, remove the curved panel, and attach a new curved panel to the newly extended dust hood. #5. Reinstall, continue with project as originally planned…

In my mockups, I found the height I picked was just about ideal, enough room for the hose to clear, not so much room to make the collector capacity ineffective…

If this works at least as well as the cardboard / duct tape and flex hose mockup did, then this will be a winner for my shop!

The nice thing is that I have a gap between the top and the bottom of my library cabinet, I hadn’t planned it orignially this way, but this would make at least a passable storage area for a few oddly sized pieces that have no home. My framing nailer leaps to mind!

Duct tape, and tell everyone it is for a flexible installation. Working on the exact same issue.

The prevention of errors in creating new objects, be they furniture, jigs or shop fixtures, is always the major factor slowing me down in the shop. If possible, I like to do a SU plan if the item is complex, and it has a simple interface with its intended surroundings (call that interface), such as a sled and the TS top. For very simple objects with a simple interface, most of us don’t bother with plans and that includes me.

Speaking primarily about shop stuff, which as you are aware is my only expertise…......(-:

The most difficult thing to build is a complex object with a complex interface. Just what you would expect. But there are different levels of difficulty there, also.

My current bugaboo that is coming together slowly, is the combined outfeed table and dust control box for the TS. The interface there is so complex, that I haven’t been able to get my head around making a plan. So I move excruciating slow. If I had realized the time this would take, I would have shed a few tears, and retired my 24 year old Delta Contractor’s saw, and bought a new saw with the requisite gizmos. However, being new at doing woodworking as a hobby, I just kept on hot rodding that saw and getting add ons for it, as each new requirement occurred. Now, I really don’t want a new saw because it functions flawlessly, and is very accurate and easy to use. I have made some pretty interesting items to control air flow on the saw, and I look forward to posting it. But I won’t recommend anyone else do it!

Adding a vise to my multi-purpose bench was a perfect example of a complex object with a complex interface, but one that was amenable to doing a SU plan.

It’s the things that move, such as the motor on my contractor’s saw that really create complexity. And I want to be able to detach the outfeed table easily for cleaning, repairs, adjustments, etc.

But it is getting close. I took some time off the project recently to make a jig for cutting long thin strips, and it is nearly done. I pretty much have figured out everything, but I never made a plan, except for an item or two to control air flow.

I am not sure where your miter saw project belongs in my categorization of projects, but I suspect it is a complex object with a complex interface. If it were of the right sort, a Sketchup plan may have been worth the effort. But that takes time, and you have been short of time lately. I could make some Monday quarterbacking suggestions, but I bet you have it all figured out now. I think the lesson I have learned in all this analysis is that you better make a plan for anything that is complex, and amenable to it. If it is a complex object with a complex, interface…......and is too difficult to make a plan…....then figure out a different way to do things, or abandon the project.

If I had been as wise as I am now, I would have probably abandoned my project, and bought a new TS.

Your project would probably have been amenable to a plan. But you didn’t have much time and you winged it. I do the same thing at times. But that is when we make our biggest mistakes, I suspect.

I always say that wisdom is the product of getting old and having made more mistakes than the next guy, and hopefully learning from them.

Have a nice day, off to work….......
