What’s It #22 – an inertia ring

My computer failed me … well, actually it is not the computer but the Windows 10 evaluation preview.

I won’t have access to my photos for a week or more. In the mean time, here is a textual description.

Inertia Ring – a weighted ring, mounted to a spinning shaft to deal with engine combustion pulses at low at RPM – most often at starter speeds. It is just a “hunk of metal”, albeit a precisely balanced hunk of metal.

An inertia ring should not be confused with a harmonic balancer which is designed to address harmonic pulse frequencies at high[er] RPMs.

Doubling the paint booth

There are some common axioms such as “you can never have too many clamps” and “measure twice, cut once”. There is another, “there’s no such thing as too much space”.

When I need to handle a large number of flat pieces, it’s handy to have two levels of work area in the paint booth. I built a frame which is attached to the ceiling by pulleys and ropes. The lines all run to one end of the booth. By hooking the rope in one of two positions I can lower the frame into painting position or raise it over head. This allows me to have two layers of work.

I can use this setup for the initial coats of finish when some amount of over spray will not be critical. However, for the final coats, I need to be able to have the finish flow out perfectly smooth so I avoid any uncontrolled spray.

This setup cuts my finish time by about 40% for the pieces.

Mission McCoy Dining Hutch – full inset doors

The upper portion of the Mission style McCoy Dining Hutch is nearly ready for final finish.

Even with the shop hitting 90F today, a fan and some natural breeze made the 7hr day bearable.

The six full inset doors were cut, routed, glued, trimmed to match fit, sanded, and stained.

There was just enough down time to tear apart one palm sander which had been over heating. It turned out to be clogged from years of fine grit sanding. I suspect the humidity didn’t help either.

In the photo, the far right door has its hinges set in place. Before final finish, all the hinges will be fitted to insure there is the necessary 1/16″ gaps on all sides.

Rails and stiles with a single router table

One of the challenges to creating rails and stiles for furniture doors is getting the complimenting cuts aligned in all three dimensions. Large shops have separate dedicated stations.

It’s not difficult to do all of rails and then do all of the stiles. However, all it takes is one mistake and you have to swap setups. Getting the alignment correct to match all of the prior work is tedious and a lot of trial and error.

While I would love to have multiple router tables, I’m not that busy yet. I do have multiple routers. My compromise is to have multiple inserts for my table. I can setup one router for rails and another for stiles. I get each aligned and then I just drop in the setup I need. I can swap between rails and stiles reasonable quickly.

I had some old scrap plexiglass so I cut it to match the size of the original insert. I then taped them together and cut the center hole. I did not match drill the mounting holes since those are specific to the router and my routers are different. I used the second router’s base plate to find the right locations to drill and counter sink the three mounting holes.

Now it’s back to making sawdust.

What’s It #22?

I doubt very much anyone will get this as it is an obscure item. I will say it weighs about 11 pounds.

Material handling in a one-man shop

I’m not a big fan of unitaskers but when it comes to protecting my health in the shop, I’m not opposed to having the right tool for the job, even if it only has one purpose. That is the case for the Gorilla Gripper.

It has the clever ability to hold a 4’x8′ sheet of plywood without unnatural stretching or reaching.

I’ve tried rolling handles and other means of moving large awkward sheet stock and nothing has been as consistently easy (and small).

So there you have it. A unitasker I’m not ashamed of having in my shop.

BTW: the other unitasker I have is a fire extinguisher!
