This is the coolest tool I have right now. It way out performs my other Magnet Matcher and is much more consistent. It's made by US BALANCE model US MAGNUM-1000XR. This unit was picked up at Harbor Freight on sale for less than $15. Nightrider tipped me off to this technique in a phone conversation. He said he got the idea from Shipsgunner. Note that the readings from one scale to the next can vary but as long as you are using the same one then you will get accurate readings that you can compare magnets with.
US MAGNUM-1000XR already has a metal platform. If you have one that doesn't then simply glue a flat piece of steel to yours.
I did drill a hole above the on/off button for easier access. Otherwise you have to take the plastic cover off every time it times out which is about a minute.
Once you turn it on let it calibrate itself. It should now read 0.0 grams.
Notice I have some markings on mine done with a red Sharpie. I did this for reference points so I can get my magnets close to the same position.
Here is a G plus Motor Magnet. The scale is going to read negative grams because your actually pulling the platform to the magnet.
Shown here is one of my MMPS cars. I'm checking the down force it has. I have my reference marking for the front and rear tires so I can place it around the same spot every time. This is similar to a magnet marshall for 1/32 cars. I've noticed that a lot of my cars have way too much down force. On my scale a negative pull of about 9-10 grams seems to be working well in this class.
and this scale is also used to measure weight. Simply turn the tray over and recalibrate the scale and then place your car on it.
This also measures the weak original tjet magnets. You can't beat this simple way of testing magnet strength and matching your motor magnets. Compare this price to a Gauss meter and to me the choice of purchase is simple. Alright, now stop holding tech tips back Dan and Chris ;D
