John Keene: I have that exact RAS I'm trying to find a manual do you know where I can get one ?
Mech Uno: The best one that I have seen. I will be copying it. Thank you!
Ben Hatcher: @B Anon: the fence height is limited by how much clearance there is under the motor housing with the blade 1/4 below the table.
Only on the pull stroke does the blade push chips DOWN into the collection stream. A push stroke would throw them up into the blade guard or air.
B Anon: Thanks for such an excellent idea. I knew there had to be a better approach to dust collection on the radial arm saw than just having a big open box behind it and hoping most of the debris happened to go into it! I'll make mine higher so it catches all the dust from cutting 2x. I also don't see why there would be a problem using this when cutting miters. Just pull the saw full forward, set the angle, and very gently back it into the box.
Ben Hatcher: tonkatoytruck, I did cover the blade guard port. This was as much a precaution to prevent flying debris as dust control. I'm far more concerned about a hole in the blade cover that points directly towards me than the theoretically possible dangers the safety police who commented previously pointed out. Unstable knots throwing off chunks are a real and relatively common thing.
tonkatoytruck: I have the Craftsman 100 RAS. A little bit older than yours but very similar. Dust collections has always been a problem. I really like your design and it seems blocking off the vacuum port on the blade guard was part of the improvements. Thanks for sharing. Mine was bought around 1968, if I can remember correctly.
Larry Taylor: Good job. I think I will copy & thanks for a great idea.
Ric Ornelas: Great idea.
hatcherb: Ray, I thought I demonstrated a dado cut in the video. Provided you cut your dados on the pull stroke, most of the chips will be collected by the low profile hood. The blade width doesn't matter.
Ray Witmer: I use my radial arm saw similarly on a bench with a compound miter saw sharing the same fence to the right. I use my radial arm only for dadoes. Do you think this would still work? There is no table kerf because the dado does not go clear through the board. Plus it is obviously much wider than a singer blade.
brandon spun: Great setup. I would suggest not leaving that remote control on your dust shroud.
hatcherb: The vacuum is a Delta 50-760 1.5 hp dust collector.
mushtaq Ansari: Great job.. Do you have the plan for the Vacuum
hatcherb: True. I don't often make angled cuts with this saw. I do those on the table saw. I'm in the set it at 90 and don't move it camp wrt the ras. However, I have made some either by clamping the workpiece to the saw table or by adding angled blocks to the fence.
robsgaragewoodworkin: Very nice! Great idea! You are only making straight cuts so I'll have to make modifications for mine...
hatcherb: I've posted a second video that shows the inside and underside details. The concept is pretty simple. A kerf goes through the top and the area under that kerf is more or less sealed and the bottom slopes toward the back where the dust port is located.
Angelo Pacifici: great setup, can you share some more details on how the slit is setup and the vacuum draw.
mototree: do you have a vacuum hooked up to it on the underside could i get some pictures of the underside? nice design!
hatcherb: Ted, thanks for the compliment. I haven't changed anything and the short fence hasn't been an issue yet. The base is pretty simple. I boxed in the cavity below the blade, added a chip ramp, and a 6" port on the bottom rear. There's an additional hole in the top under the triangular piece for above fence collection.
I'm unsure if the model year. Probably 1960's.
imtediam: What year was your RAS manufactured, Hatch? I've never seen that make before.
