How can you test a capacitor? If the resistance is gone then it's obviously dead, but what other easy tests can you use? I had a motor on a saw which sometimes...
Depends on the type a bit and the equipment available. If you have a moving coil type meter, set it to resistance and put the leads across the C (red to...
I have heard of this test before but I don't have an analogue meter - I was hoping someone else might come in with other suggestions. Any more ideas? Philip ...
Each type of capacitor is a little bit different to test. If you have a "-" negative sign on one of the leads this lead needs to be always kept at a higher...
You could use a moderately large resistor, a voltmeter, and a battery... Measure the resistor, calculate the RC time to charge the cap, put the cap and...
Hello EDMHomeBuilders, Recently we launched projects pages and are looking forward to populating them with your creations. (We can even link it back to your...
Dear All, I bought the EDM how-to book recently, I would like to know the value of resistor, capacitor, voltage and how much time was required to produce "EDM"...
The electrode used to make the image on the back of the book is 3 1/2" long X 1" wide. The burn is .062 deep. It took two hours to burn. The value of the...
Just out of curiosity, before I try to build this machine, is there any indication as to the cost of all this electricity? How much did it actually cost in...
Harbor Freight and many other place sell inexpensive electronic multi meters that will let you test capacitors. These sell for less than $30.00 US Still if...
Garry, At the national average cost, you’re talking about 42 Megawatts of electricity. That’s enough electricity to melt 90 tons of steel. Are you sure...

He said "a little of" I'm assuming that the 4 grand was an annual electric bill or something, and that some (unspecified) portion of that was used to melt...
Stephen, I don’t know if anybody has actually metered the AC power on these units. However, based on the transformers used and the average residential KWH ...

Actually I figured the question was so silly it deserved a nonsense answer.... Garry...
The PCboards are ready for shipping. This is an exact drop in replacement for the point to point wired board described in The EDM How-To Book, see the attached...
Hi Ben, How much to Australia? If you tell me on-list then the other Australian list members will know also and save you replying multiple times. Yes I want...
Looks like a real nice, pro job, Ben. I'll include it as a news item in the January Model Engine News. May sell a board and book or two--now get 16,000+...
Here's a preview of the article "Knurling Made Simple" posted on the new 'Articles' section of the ProShop Publishing site. If you wish to view it complete...
Why is any question silly? My guess is the person did not know how much one of this type of machine could cost both in terms of electrical cost's and possibly...
Ben this is great Thanks the board is great what more can I say you know I have already ordered mine just wanted everyone to know it is good to have this done...
Hi Ben, Very nice looking board! I actually wanted to wait for the Pulse Machine Book and board to come out. Is there any prospective date this will be...
Ben; Could you post the PCB pic in your flyppc photo folder? GAB ( and yes I want one {or 2} too, hope you had plenty made up. ) ... replacement for the point...
