#350 Table Saw
This page includes information my General #350 tablesaw and accessories, including the Biesemeyer Fence, JDS Accu-miter Miter Gauge, Powermatic mobile base and Freud saw blades.
I purchased my one-owner General #350 back in early 2000. I believe it is about 10-15 years old. Mechanically and cosmetically it is in very good condition. The commercial Biesemeyer fence was included, as was the original motor cover, miter gauge and manual/exploded parts diagrams. It was missing some pieces when I purchased it, including the blade guard, extension table and extension table legs. I've upgraded the saw by replacing the missing components and adding some others new accessories. I've included alot of links to Amazon.com for the various accessories and parts that I mention. The original 6 page manual/exploded parts diagram for this saw is available in Adobe Acrobat PDF format.
I had a major problem during installation. One of the cast iron mounting brackets had to be machined to fit properly. General changed the design of the saw slightly, so about 1/8" had to be machined off the bracket to allow it to fit on my older saw. I have a machine shop available at my office, so it was easy for me to fix at no cost. General also offered to machine the bracket for free (a money-losing proposition for them). Their support was been very good when I ordered the replacement parts. They returned my calls very quickly & professionally. General is located in Quebec, so be prepared for a French accent if you call them on the phone.
The guard itself is only fair, which is typical of the standard guards from almost every manufacturer. One big complaint is that the blade guard (and front bracket) have to be removed during miter cuts. The front bracket runs up into the blade insert if it isn't removed. The aluminum sides also obscure the blade more than some other guards with clear polycarbonate sides.
I implemented one simple enhancement that makes the guard much more convenient to use. I replaced two 3/8" bolts with push-button rotating adjustable handles (about $5 each). The two handles are circled in the photo below. This allows me to swing the guard out of the way without tracking down a wrench. I purchased the handles from MSC, but they are available from several other sources like Reid Tool. Neither of these websites make the handles easy to find, so I'd recommend that you just request a printed catalog from them. McMaster-Carr is a better on-line source (and a great source for almost anything else you need too!).
The handle on the right is rotated so it can be seen easily in the photo - although it looks close to the blade, there's at least 1" of clearance. It's normally rotated straight down, which gives even more clearance -there's not a chance of it hitting the blade. It's also plastic, so even if it did hit the blade, it likely wouldn't cause any problems. The handles come in several different lengths, different thread sizes and with both internal and external threads, so there's a good chance you could find one to fit for almost any application.
The only mobile bases that would fit the General #350 were the

didn't seem as solidly constructed. It looks like it would be
to rock with the way the wheels are located under the table saw

The wider footprint of the Powermatic mobile base has worked well for me, so I can recommend it for any other #350 owners. Since it is designed for the Powermatic #66, I am sure it would work equally as well for that saw.
Biesemeyer Fence(click picture to the left to see a larger image)
The original Biesemeyer or similar T-square fences are included with many popular saws including the Delta Unisaw, Powermatic #66, General #350, Jet, etc. It's also available separately for retrofitting old saws. The Biesemeyer fence is rock solid and dead accurate. I especially like the little recess on the top of the fence, as it is a great place to store push sticks . A push stick that is easy to grab is much more likely to be used.
One dislike is that the fence is heavy and relatively difficult to move. For a home shop, I would recommend everyone seriously consider the Delta Unifence. I used one briefly a few years ago & it seemed like a nice, versatile fence. The rigidity and reliability of the Biesemeyer would be great for a production shop that uses the saw several hours a day, but the occasional home-shop craftsman may find the Unifence to be more suitable.
I am planning to replace the melamine-coated face boards with UHMW as detailed here. I am planning a few improvements. First, I plan on making a special face with a cutout for my dado blade. Second, I'll add keyholes, so that the faces are easy to remove and replace. I'll add detailed pictures after I get finished.
One minor complaint is that the fence locking handle falls
locks the fence in place when it is being moved. It's almost
operation to move the fence - one hand to move the fence and the other
to hold the locking handle in the "up" position. I recently
with a new Powermatic #66 at the local Woodcraft store & that
fence handle locked in the "up" position. I need to go back
closely at the new #66 fence to see what's different, as I bet I can
mine so it also locks "up".
|I purchased a new set of Biesemeyer extension table legs since the original ones were missing. I could have made some simple legs out of wood, but decide to go ahead and get the nice, matching steel legs. They work fine, but I had to remove one of the included locking nuts to get the legs low enough to fit the #350. The legs are nicely made & powder-coated. They aren't just for extention tables - they could also be used for outfeed tables as well.||
|On order, but not yet installed is a new replacement scale for my fence. I wanted one with 1/32" graduations, and I did not want one with dual metric graduations. The combination metric/inch rules would be a distraction for me since all my work is done in inches. Biesemeyer had the perfect scale as shown to the right. It was the only one I found that would work - most of the self-stick rules are only graduated to 1/16".||
I generally followed their recommended construction with a few changes....First, instead of using particle board, as Biesemeyer recommends, I used 3/4" birch plywood. Second, I added a second layer of plywood under the end of the table for better support of the router table. It was covered on both sides with ivory-colored laminate from my local Home Depot. The ivory matches the pale green color of the #350 pretty nicely. I used 3/4" solid birch for edging around the entire extenstion table. I'm not sure if it is really necessary to laminate both sides, but I did it anyway, as it may help prevent any warping. I made the extension table so that the table legs would be in just the right position to sit on the mobile base.
I still need to rabbet the hole to accept a router insert. I already have a 3/8" thick polycarbonate plate to fit into the hole. You can buy the 3/8" thick polycarbonate from McMaster-Carr or get it at a local plastic supply house (look up "plastic" in the yellow pages). My plate is about 9" x 11", which fits my Porter-Cable #690 router nicely. You can also find pre-made inserts in almost every woodworking catalog, but they will likely be quite a bit more expensive..
I plan on making a special attachment that clamps or screws onto the right face of the Biesemeyer fence, so the tablesaw fence can be used as a router table fence. Check back soon for more details on this.
The Accu-miter is available from many typical woodworking sources, including Amazon.com. The Accu-miter doesn't come with a bar. You can buy a special bar (the Accu-Bar) or drill and tap your old bar to fit the Accu-miter. I also bought the Accu-bar, so I could (infrequently) use my old miter gauge on my sander or bandsaw. It would also seem to be pretty time-consuming to drill and tap all the required holes in the old bar, so I'm glad I bought the matching bar. Assembly was very easy. Adjusting the scales so everything was square and accurate was also pretty easy. There is also a matching stock clamp (not shown in any photos), but I did not buy it. The stock clamp seemed too clunky & would likely get in my way. Here are links to the Accu-Miter and Accu-Bar at Amazon.com or click on the images below.
I'm very pleased with it so far. The repetitive cutoff stop (up to 34") is very nice. It's already saved me alot of measuring and marking time. I haven't cut any miters yet, so I can't comment on the accuracy at angles other than 90 deg. I'm guessing that it will work very nicely. Others have said that the Accu-miter is too heavy, but it really doesn't bother me. I actually like it, as it gives it a nice quality feel.
One minor annoyance - the scale on the sliding piece from about 19" to 34" was a little inaccurate (off by 1/16" or so). There's not a nice sighting line on the scale - you just sight against the edge of the aluminum extrusion. The sliding piece also pivots with respect to the main extrusion, even when the locking handle is tightened, because of the clearance between the two pieces. It's really not an ideal design. There also doesn't seem to be a good way to adjust the scale other than peeling it off & sticking it back down. The two sliding aluminum pieces also have a tendancy to move a bit when the screw is tightened, which is very annoying and leads to inaccuracy. It's possible to shim the end stop depending on which direction the scale is off. It's still not perfect because of the lack of an accurate sightly line. I may be able to improve it some more, and I may contact JDS to get their comments. Any good info will be added here.
Well, it is a little expensive, but it is nicely made & has a quality feel to it. Some of the features (repetitive length stop) could be done with a standard miter gauge with shop-made wood accessories.
Basically, two thumbs up. It's a nice tool that will be a good addition to my shop for a long time. I just wish the 19-34" scale was a little more accurate.
The dust collection works pretty good, but there is a great amount of sawdust that collects on the flat bottom. A more complicated angled bottom would likely improve this, but I'll probably just live with it. I just manually brush the sawdust into the port when alot has collected in the bottom.
Newer #350's already have the dust collection port as circled below::
One minor improvement that I made was to move the electrical switch forward where it is easier to reach. It was originally mounted to the cabinet (the original two mounting screws are circled in the photo). I added an aluminum angle to the fence & moved the switch forward. It's much safer to use now & I can use my knee to turn off the saw if needed. Newer #350's already have the switch mounted like forward as you can see in the picture of the new #350 shown above.
While we're on the subject of electricity, this saw has a 3HP motor. I'm running the saw off of a 20amp, 220 VAC circuit breaker. I've seen some other people recommend a 30 amp circuit for similar saws, but I haven't found it to be necessary. I would recommend that you run 10awg wire for this saw. That way you could use a 30amp breaker if you ever needed to.
The sawblade arbor was perfectly good with no runout, but the sawblade flange had about 0.003" of runout. Who knows how the flange got its problem - maybe it was an original manufacturing flaw. It doesn't sound like much, but 0.003" is enough to make the blade noticably wobble. I very carefully filed the high spots, so the flange has less than 0.001 runout. I don't recommend that most people try this repair. I've got the proper machinist measuring tools to accurate measure where metal needs to be removed. I just mention it here, because it's an odd thing to have to do.
I am almost exclusively using a Freud 50 tooth combination blade. I also have separate Freud Rip and Crosscut blades, but I haven't found it necessary to use them. I get nice smooth cuts & the saw has enough power to smoothly cut through 6/4 maple with the combination blade (6/4 is the thickest stock I've cut so far). In the future, I may try a more expensive Forrest "Woodworker II" combination blade. The Forrest gets consistently high reviews and makes a thinner kerf than the Freud blade I currently have.
Dado Blade Set
I also have a Freud dado set, which works quite well. The bottoms are nice and smooth. There are a couple of things to note, first, to fine-tune the width of the dado, you'll need a set of shims. You can buy shim sets from Freud or Jesada (hint: the Jesada set is MUCH less expensive). It's also possible to make your own shims. I've sucessfully used thin strips of cardboard & just drilled a hole in them with a 5/8" bit.
The second problem occurs on wide dados that require multiple passes. The two outside blades have sharp nickers that cut a little deeper than the normal dado depth. These nickers make for pretty clean cross-grain dados, but they have a downside. On wide dados that require multiple passes over the cutter head, you end up with very thin parallel cut lines in the dado, where the nickers cut a little deeper. I'll try to get a picture to show this, as it's a little difficult to explain. A few passes with a sharp handplane will remove the cut lines, so it's pretty easy to fix.
