MPH Finally makes it to Oregon


 Driver couldn't get his trailer up our street so he just pulled over on 199 South about a 1/4 mile South of us. Truck left VA on 3/24 and arrived today, 4/23. Driver got stuck in a dinky town in NV with a dead oil pump for 7 days. Mirrors got busted off, no surprise there, forgot to remove them when loading the truck onto the trailer...

Unloading engine Ted built


 I knew it would not fit with the crane attached but ya just gotta find out

Ted engine going to OR via MPH bed

Today was a bummer. Went to the back yard to move the engine pallet I made years ago to the garage and start preparing it. I was shocked to see had disappeared!!! Apparently I had tossed it and completely forgot. So I had to go to Lowes and buy lumber to build another.



 After test fitting the engine in the pallet I thought I would just leave the engine in and move the whole shebang at once


 Saw this at Cheesecake Factory, hard to see but that hoodie says Snap-On on it.

Door Latch Mod

This is a mod to add a key lock to the driver's side latch. In addition what is shown here is the drilling of the hole for the lock to mount on the door skin and installation of the lock.

 Existing driver's side latch

 Three tabs to bend up

Old School Sun Tach

************************* UPDATE **************************

I had issues with lower RPMs so I had to find the problem and modify the design. At first I thought the issue was that the voltage regulator was dropping out as the tach worked great at higher RPMs but acted eradically at lower RPMs when various loads where turned on such as the heater.

When I investigated I determined that the DIST input signal didn't have an appropriate return path to ground. Because the circuit is a negative ground design and the truck is positive ground the signal return path actually was through the voltage regulator. Not good. So I had to electrically isolate the DIST signal return path from the circuit and a pulse transformer was the ideal solution. The transformer also allows easy polarity reversal.

Here is a .pdf tothe modified design: https://dl.dropboxusercontent.com/u/13355828/STT/Tach/Layout2.pdf



I purchased a Sun Tach and controller off ebay and decided to upgrade the antiquated technology inside the controller. This included gutting the controller and adding a circuit board that mimics the old relay/Mercury cell design using a 555 timer IC. The timer IC is triggered by the distributor and generates a consistent voltage and pulse duration. The meter then integrates these pulses to display pulses per minute which correlates to RPM.

Here is a link to a .pdf of the design: http://dl.dropboxusercontent.com/u/13355828/Tach/Layout1.pdf

This design is based on this I found on the Interwebs: http://myplace.frontier.com/~wgmumaw/Sun%20Tach/Sun%20Tach.html

And a video showing the results:

 I suspect that at the higher RPMs in the test the drill runs a bit slower because of the added load. Of course I have no way of knowing how far off the drill is since I don't have tachometer to test the speed. I have yet to install the controller and head but I don't expect any problems.
