Hey guys, a month ago we did not own a Ras. Now we own two. I’m going to install the 7730 right next to the 790. This 7730 is smaller then the 790 and the two don’t compare. The 790 accelerates to full power immediately, the 7730 takes slightly longer to get to full speed. It does seem to run fine though. We paid 80.00 for it. The arm gives us 17” cross cut capacity. I am going to run a single blade on it for just 90 degree cross cuts. I had a request from my workers to add a second sliding miter saw because we end up log jamming at the sliding miter. So now when one needs to cross cut and the miter is being used they can just go to the 7730. And we are inheriting the Ridgid Raw that has never been set up, the family member never used it. When we get it I plan to set it up with a power feeder and use it as a rip saw for hardwoods.

The 7730 seems a lot less powerfully then the 790 but it should be fine for back up cross cut duties. Our 790 runs the dado blade and runs great, I absolutely love that saw.

Pics to come later.

Plus we have three kitchens under contract and they are all coming due soon so I anticipate being able to really get a fair amount of use from the 7730. We, or at least I am excited about our new addition.

Oh, they are great to have if you have the space.

I don’t know about others, but I prefer to push the radial arm carriage
into the work. I feel it is safer. It does make the work go slower though.

That makes sense Loren. Good observation. So chip out would be on the top side of the wood.

Well, sometimes when you pull the carriage it can grab the
wood and rush into the cut towards the operator. On some saws
you can tighten the mechanism so the carriage doesn’t slide so
easily to slow it down if this occurs.

The way the blade spins on a RAS is opposite the way a table
saw blade spins in relation to the wood in crosscutting. Making
the pull cut is equivalent to feeding wood into your table saw
from the back of the blade. There are, I’m sure you know, special
blades for radial arm saws that deliver the best cuts in pull-cutting.

Have your say...
