I've never owned or used a radial arm saw. And if I ever come across an extra few $1000 to spend on a large rig, I'd go with a table saw, simply because I already have experience on them. If someone gave me a radial arm saw for free, I'm sure I'd find things to use it for.
Anyway, in the spirit of the thread, I think it would be fun to see the radial arm saw owners talk about what they've done to make their saw safer. Whether by safety contraptions, or technique.
I added lots of high Kelvin LED lighting above it so there's no shadows.
Converted to 220VAC for better power ... and much less slow down in cuts.
I always draw the saw with my right hand as it is more powerful than the left ... for better control.
I allow it to hog-in and stall once in a while to retrain me of its capabilities.
Keep the front/entry area of the rotating guard very close to the work even though at that place the blade rotation is pushing the work tighter to the bench.
Always cut distorted wood cup-end-down.
Try to not cut distorted wood.
Never cut a diagonal unless the whole workpiece is supported along a fence.
If the cutoff drops into the unsupported acute angle of the fence, it can throw the cutoff piece a goodly distance or jam the blade ... the same as a table saw.
If it throws cutoffs, they go to the right, so keep that trajectory in mind.
It WILL stall if it hogs-in, so I know its limits.
The only time I felt really ill-at-ease was ripping green, wet, 10 foot long planks by myself... even using the one way finger guides ... and I just took those cuts to my table saw .......... where I was still concerned about getting speared..
