The sanding war-wagon

Now that the corner bench is finally going in, I am so pleased with the results that I want to share what is for me a delightful discovery: the orbital sander with vacuum attached.

I know, "Big Deal! Orbital sanders have been around a long time.", but this is working out so much better than my previous experience with orbital sanders, that I think it should be shared. I have been using a 1/3 sheet orbital sander for more than 10 years, but I didn't have great success getting it to work with the vacuum.

Because of my bench project, I invested in a cheap 5 inch (12.7 cm) round orbital sander with hook and loop sanding pads. It didn't really connect well to my shop vacuum either, but I salvaged a duct from an old vacuum cleaner that serves well as an adapter. After some trial and error, the results have been great! I get almost no dust up in the air when sanding. Far less, for example, than with hand sanding.

A few lessons I have learned: 
Make sure you line up the holes in the paper with the holes in the sander (approximately).

You can use a painting edger to protect adjacent perpendicular surfaces.


Contrary to the instructions that came with my sander, I only turn it on when it is already in contact with the surface because, in addition to orbital motion, this sander allows rotation. Due to the inevitable  imbalance in the pad, the orbital motion is converted to rotation rather quickly when it is free-running in the air. It builds up so momentum so fast that it damages the surface when it first makes contact.

Finally I want to say that I love using it with the shop vacuum in the following "war-wagon" configuration:
This makes it very easy to sand all over the place with the vacuum following along.  Notice that the sander cord is wrapped around the vacuum hose then plugged into the extension cord (orange). The vacuum cord is only unwound from its storage coil enough to reach the end of the extension cord. The extension cord is loosely tied to the vacuum handle in sort of a lark's head.

This setup has really proven itself in my bench project, where I have sanded over 100 square feet  (9 square meters) with multiple grits.  Not only does it almost eliminate dust in the air, but it improves sanding by pulling the dust off the surface so the sandpaper has better contact with the workpiece.

Beveled Edges - A New Instructable in the Woodworking Elements Series


https://www.instructables.com/id/Woodworking-Element-2-Beveled-Edges/

This time I explained how to use the scrap from cutting a beveled edge of a board to check the accuracy of the angle.  I use compounding error by  stacking up segments of the scrap to exaggerate the angular error to make it easier to see how much to correct and to make it clear when your angle is close enough to what you want!

Build-a-bench

More instructables and videos are in the works, but for the last few weeks I'm spending my free moments building a corner bench for the dining room.  Here are some sneak peeks which I hope to explain in more detail later.  I love this photo of the bench in progress because it illustrates the challenge of doing woodwork in a limited space:
This is the reason (almost) everything in my shop is on wheels.
Here's a preview of some tricks I want to share soon:



 The bench has lids with piano hinges that needed to be trimmed with beveled edges:

I'm match-drilling and pinning the seats to the base so I can dress it all up in the installed condition in the garage, then tear it down and reassemble in the dining room later.


Chip's wood shop selfie- actually I'm using the phone to sight holes from underneath that I can only reach with one arm:

As I say, more to come, but I wanted to let interested people know that Chip's wood shop is busy getting lots more ready to share!
