Is there any chance that one of your cams is 180 degrees off? When the first cylinder fires. the next cylinder should be starting exhaust, not compression.

The combination of the capacitance of the condenser and the inductance of the coil make a tuned circuit. When the points open, the tuned circuit oscillates, producing a longer spark time. Also, since the output voltage is now AC instead of 1 DC pulse, the metal pulled from one side of the...

Video won't load for some reason. Yep... windows strikes again.

Sherline sells a cutter for making compatible t-slots. But, price is $94. https://www.sherline.com/product/t-slot-cutter-carbide/

I wanted to access my account to manage my license. However, my password did not work. So Mach locked me out after a few attempts. My ip is still blocked days later.

Mystery solved.... Mach says my ip address was banned because I entered my password too many times.

That reminds me of my mothers best friend, whose name was Airline.... because her mother didn't know how to spell Arlene.

I must be my internet provider. If I use my iPhone as a wifi hotspot, I can get in..... weird!

I still cannot get in. Website times out every time. I even tried on 2 other computers.

The machsupport.com website has been down for days.

Very nice engine! I have the plans for a Farmboy.... not sure I have the skill :)

Brian, I admire your patience and stick toitiveness :)

I'm hoping to see it run with its new carb!

Find Hansen has built several model diesel engines. For example:

Be careful, and test your combinations outdoors until you are sure that you are not going to produce any dangerous fumes.

Current capacity depends on surface area of electrodes. Voltage depends on electrode materials, and choice of electrolyte(s). In operation, the zinc will oxidize creating a zinc salt which dissolves into the electrolyte. EG: if using sulfuric acid as the electrolyte, zinc sulfate will be...

Look at the table of standard electrode potentials. This will give you an idea of what voltages to expect from different metals. For example: A copper (Cu) electrode has a potential of about +.52 volts. A zinc (Zn) electrode has a potential of about -.76 volts. Together, with an appropriate...

Sorry about your lathe. I did the same thing trying to move my Jet BD-920. It fell over onto the concrete floor and smashed the apron. It would have cost more to repair just for the parts than the price of a new one, so now I have a lot of spare parts. It could have been worse, it could have...

Hello members, My name is Bill, and I presently reside in the Pocono mountains of Pennsylvania very close to the Pocono Raceway. I am a retired engineer that specialized in Bragg Plane Crystallography, electronics engineering, and Unix system engineering. A few decades ago, I had a 6" Jet...
