[Farmall] Another O-12 project, part 4

[Mike Sloane]

A needle scaler is an air-powered hammer with a couple dozen little rods 
sticking out to do the work. It is great for removing old paint, rust, 
and other crud stuck on metal. Two limitations: they are very loud, 
sending the crud flying all over, so ear and eye protection is a must. 
And they use a LOT of air, so you need a fairly big tank and compressor. 
They are pretty crude, so I wouldn't want to use one on thin sheet metal.

This is an image I took after removing 50 years of crud from the inside 
of a Ford 2N front wheel:
