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
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.
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.
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
Larry Taylor: Good job. I think I will copy & thanks for a great idea.
Ric Ornelas: Great idea.
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.
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.
mototree: do you have a vacuum hooked up to it on the underside could i get some
pictures of the underside? nice design!
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
mushtaq Ansari: Great job.. Do you have the plan for the Vacuum
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. -Ben
hatcherb: The vacuum is a Delta 50-760 1.5 hp dust collector.
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.
imtediam: Awesome job! I've never seen anything like it. It's sleek and unobtrusive.
I'd say it's the Ferrari of RAS dust collection apparati. It's perfect for
my needs. I'm sure I have all the materials in my scrap bin, too. Have you
thought of any more design upgrades besides the taller fence. What does the
underside dust collection setup look like? Thanks, Hatch! Ted
imtediam: What year was your RAS manufactured, Hatch? I've never seen that make
Angelo Pacifici: great setup, can you share some more details on how the slit is setup and
the vacuum draw.
brandon spun: Great setup. I would suggest not leaving that remote control on your dust
robsgaragewoodworkin: Very nice! Great idea! You are only making straight cuts so I'll have to
make modifications for mine...
