Radiator build
« on: July 05, 2017, 09:08:21 AM »
Here is my radiator build for my Little Demon V8. This is the first one I have done I did attempt and failed miserably to build the one in the plans so I made up my own. Here is a short video showing it so far it has to be cleaned up and finished yet.

Well I cut one side flashing and am going to try and make the radius on the tanks smaller to blend more withe the side. Anyway here is a short video taking a peak at what its looking like.

Was going t post an update video with the soldering of the 2nd radiator but unfortunately my video card went bad. I videoed the soldering and when I went to pull the vid off camera I got a file corrupt I tried taking the card and putting it in a card reader and got the same. Dam it anyway. So I need t get a new card.

I do have question has anyone tried these tach meters I am thinking of putting one on but kind of curious as how went they work (or don't)
Here is a link to what I'm talking about.

The RPM gauge seemed to respond slow so I didn't use it. I did finish up the rad's and mounting box and gave them a little run.

It is a hall sensor so it reacts on a magnetic field. Obviously the pill supplied is not to be swallowed but glued someplace where the sensor can sense it.
So, I assume, the pill is glued on a rotating surface and the sensor attached nearby.

Basically hall sensors can detect frequencies high enough for this kind of use. The sure can do 1000Hz -> 60000 Rpm.

The electronic involved is very simple frequency counter.

These work. They will flicker on low rpm:s but stabilize as the rpms get higher.
