Loctite was the first thing I thought of.

I have never had a tool with moving parts that did not require adjustment/alignment. YouTube is full of videos on how to do this with various tools. I keep a square on a magnet on the front of my scrollsaw to check blade alignment and a 10mm wrench for adjusting the clamps. Yesterday, I discovered my lower clamp was out of alignment. It had moved so far to one side that I could not get the blade in. It was tight, so I don't know how it moved. Fortunately, I was not cutting puzzles.

That seems like a good idea.

I signed up for their newsletter previously after seeing a project with one of their free patterns.

Isopropyl alcohol typically has lots of water in it.

It's a design feature. No matter how bad you think it is, someone will like it.

I have wanted a turntable for a long time. I'm just waiting to have time to mess with it. All of the ones I looked at turned too fast for my purpose. Them I learned that I can slow the video down using my video editor.

Everclear will work and you can drink it if there is any left.

Very nice.

I made a batch of these photo frame insert ornaments this year. The photo is not very good because my printer fuser roller was bad and the inkjet printer was clogged again.

That would be great.

To test a potentiometer. Measure the total resistance: Connect one probe of your multimeter to each of the outer terminals of the potentiometer. The multimeter should display a resistance value. This value should be equal to the total resistance of the potentiometer, which is usually printed on the body of the component. Measure the wiper resistance: Move the wiper to the center of the potentiometer. Connect one probe of your multimeter to one outer terminal and the other probe to the wiper terminal. The multimeter should display a resistance value. This value should be approximately half the total resistance of the potentiometer. Rotate the potentiometer through its full range, looking for dead spots or other erratic changes. The resistance should change smoothly from maximum to minimum and back. You can also check them with the power on by measuring the voltage. If I remember correctly, the voltage is only 5 volts DC. I'm an old-school electronics technician, so I prefer an analog meter for this test and have a Simson 260 just for this sort of thing. However, you can do it with a cheap digital meter.

Since you brought it up, I don't think a rheostat would be suitable for a scroll saw speed control. Potentiometer: Typically used for low-power applications such as: Volume control in audio equipment Brightness control in lighting systems Position sensors in joysticks and other control devices Rheostat: Typically used for high-power applications such as: Motor speed control Heater control Lighting dimmer switches Power handling: Potentiometer: Designed for low power handling. Rheostat: Designed for high power handling. Internal construction: Potentiometer: Typically have a resistive element made of a conductive film or wire. Rheostat: Typically have a resistive element made of wire wound around a ceramic core.

So it seems like repacking bearings occasionally would be a good idea.

Are these not sealed bearings?

Mechanics stethoscopes are great tools, and they don't cost much. An excellent tip for the use of a noncontact thermometer and yet another use for one.

Yes, I would much prefer that we could replace the bearings.

Every machine that has moving parts wears with use. Parts will need to be replaced from time to time. How often these parts need to be replaced depends on many factors. Just because the bearings wear out does not mean something is wrong with the saw. All it means is that the bearings are a consumable part that must be replaced periodically. I bought my EX-21 used; it had been used hard, and about two years after I bought it, the bearings started to go. I replaced the whole drive link assembly. I can keep doing this for many years as long as parts are available. The important thing is that parts and support are available.

Speed has to make a difference. When I got my first variable speed saw, I ran it at full speed all the time. That was what I was used to. Now, I run it at the speed that seems to work best for what I am cutting.

Potentometers are cheap. Check this out.

There is nothing special about the variable speed pot on the EX21. All it does is change the control voltage. I would not pay $55 for one. I would buy from eBay if I could find the correct potentiometer there. My guess is Seyco's are made up special for people who can't solder. Why do they use these? Because they can buy them in bulk for pennies.

I changed my link arm assembly a few years ago to fix a knock issue. I bought my used, and it had already been ridden hard. I used it for a couple of years before the problems showed up. I replaced the entire assembly for the speed on Ray's recommendation. The instructions that came with mine were not very good. A crowfoot wrench will come in handy. I would not trade my EX21 for a Hawk, or any other style saw, even if I had to rebuild it every few years.

If you scroll down the listing, it shows a US plug. I think you are safe. Try this: go to aliexpress and search for "router trimmer". I'm tempted to buy one just so I can use the accessories.

Be sure to check the sizes on everything, and I don't care how many times it gets repeated 19mm is not 3/4 of an inch.
