Radial Arm Table Spacer

Happened to run across this, wish I had seen it years ago, he used washers, thin wood pieces glued to fence would work as well.

I hated the 3 piece fence .....

It was a pain in the neck in so many ways. I used a single piece of 3/4" plywood with counter bored holes for the hold down bolts and washers. It extends about 40" to the left and 20" to the right of the blade. I aligned the fence to the blade using a framing square and a flat alignment disc on the arbor. When it was square, I added a second and third screw on either side of the kerf and snugged it down. It has a sawdust rabbet on the face to allow for small amounts of dust build up.
The left side of the fence is longer to allow for a stop block to be clamped on for multiple piece work accuracy. The RAS, is one of my favorite machines. I used it yesterday for a quick cross cut on 1/8" plywood. The piece was a bit too narrow, so I used a 8" square 3/4" reference block against the fence to make the cut accurate at 90 degrees.



Not meaning to steal your thread, just giving my solution based on many years of using the "evil machine" ....... as Rich called it.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

The three piece fence is there for a reason, it is your choice if you use it or not, part of the "evil machine" reputation comes from "improvements" made to it.

The term "evil machine" was first used here by R Rich, to describe my setup for straight line ripping 14 foot long Cypress boards. The RAS had and still has a reputation of "climb cutting" over the top of the workpiece when crosscutting and that is my impression of where the term came from, but I could be mistaken? The wrong hook angle on the blade which was too aggressive, is largely responsible for that issue and since the RAS came out many years ago, blade design has vastly improved. We now have negative hook angle blades, and I bought my first one a few months ago, an Oshlun 10".

I don't know what "improvements" you are referring too? Can you be more specific? Improvements made by saw's owners or the factory?

Yes, the 3 piece table had specific reasons for locating the fence in two different places, none of which come to mind at this writing. Possibly for vertical orientation of the arbor for shaping ...?

FWIW, I stumbled upon this great article on setting up a RAS:

As I said it is your choice to do what ever you wish to your tools, not going to get into this any further, end of conversation with me.

Obviously, we can all do what we want with our own tools, that's a given. What makes us a better woodworker may require a "modification" to an existing tool or machine because it improves accuracy, safety or efficiency. That's mostly what I like to do and "My Photos" is filled with machines I have either built or modified to suit my needs.
I have received countless approving comments on my Craftsman triple 12" table saw over the years and have had several members duplicate it with 2 saws, Ledhead for example. He came to visit, saw my setup and went back home and built his own from two 10" Rigid saws mounted side by side.
Necessity is the Mother of Invention, so improvements that make a safer or more efficient machine are a good thing. Modifying or eliminating safety devices are probably a "bad" thing, but I'll admit to having done so. The designers or engineers of a product are only human, and they are not always right. I know this because, not only am I an Industrial Designer MFA with 35 years experience, but I've worked with some of the best in the business. Some designs make it to production but are certainly flawed and the consumer is stuck trying to make them work, BTDT.


Cheers Frank, keep up the good work!

I also recently purchased one and it makes a big difference.
As far of build up on stop blocks, I chamfer the edge 45 deg against the fence, I also have an air hose to blow it clean when needed.

Probably everyone but me knows how, but how do you hold down the washers for chamfering?

Grip toward the outer edge with Visegrips, lay rest of washer on a block of wood on the drill press table.

Put washer upright in vise gripping outer edge, chamfer with hand drill.

"Yes, the 3 piece table had specific reasons for locating the fence in two different places, none of which come to mind at this writing. Possibly for vertical orientation of the arbor for shaping ...?"

3 piece table actually locates the fence in three different positions
front most(common position) allows crosscuts of material as thick as the saw blade can handle, next position back is to be used for crosscutting 3/4" or thinner material, back against the clamps is for ripping only, the front two positions are more limited in how wide they can rip.
ripped over 1500 lin feet of 3/4" Baltic Birch with my Rigid Radial Arm Saw in the last two weeks with one helper to catch on the outfeed side.

felt total safe the whole time due to the guard on the saw having a riving knife along with anti kickback pawls and a slide down piece on the entering side to hold the wood down. Did burn up 4 DeWalt blades, 10" 40 tooth carbide, cutting this

Woodnthings,
You made my day quoting "Evil Machine". LOL
FrankC,
I tried something similar over 20 years ago.

Remember I had an early 1970s Craftsman RAS, ten inch. For 1971 it was probably the best RAS but then it was an RAS.

My solution was two fold. First was to chamfer the edge of the front table next to the fence, about ľ inch. Also when preparing to cut something I would slide the wood into position from the left. this would clear out any swarf left on the table and allow good registration against the fence.
