I bought one of those saws for the install crew. The riving knife was never installed and got tossed in the garbage.
So no help from me. Nice saw though.

Thanks anyway madts. Can’t believe they threw away the riving knife! I made my first rip cut with the saw today. Came out super smooth which was a refreshing change from the performance of my combi machine table saw. I’ve been buying Dewalt tools lately and while they might not be the very best available they have all been performing to my expectations and seem well engineered and built.

I don’t have that saw but if the holes line up with the mounting holes for the riving knife, I would assume they are shims to help you line the riving knife up with the place. However, if you change the blade you may have to add or remove some of them.

If you need more shims than the 3 provided, I would suggest a plastic gift card as a shim. They are 1/32 inch thick. I use them for all kinds of things in the shop including shims.

Thanks for the reply Tyvekboy. They don’t line up with anything on the riving knife so I’m sure they are meant as a replacement for a part that wears out or maybe a shim for something else on the saw.

I am not an expert on riving knives, although my saw here in La Conner has one. In theory, I guess the riving knife ought to be the same thickness as the blade, but maybe I am giving too much credit to the function of the riving knife. If it lined up so that the edge of the riving knife was at the edge of the blade, or even slightly more, meaning towards the fence, that might not be all bad. But that is all just hot air, since I don’t know much.

Really just wanted to say hello, in any case. Kink in my back today (old problem) but should be down in the shop the next few days finishing up some speaker stands. Temperature is 53 deg F here in La Conner, a lot warmer than Anchorage, and the grass and ivy are green. Welcome change from the frigid North.

Hope you and family are doing well…

Hi Jim, Good to hear from you. I think the climate in La Conner must be similar to our climate here. It’s been stormy and wet today, but warm. No problem with the riving knife now that it’s shimmed. I just need to find out what those extra parts are really for.

We are doing well here, and I finally got my shop cleaned up today. It has been a mess since I finished my elephant bowl! My son has just finished some speakers too. He told me something I didn’t know about, and that was that the leads give better quality sound if they are thicker and that the metal used to make the wire also makes a difference, with silver wire being the best available. He said it made quite a difference. His company’s landlord was the owner of a store which sold sound systems and other electrical appliances and that is who told him this. Does that make sense to you? I’m not much into sound tech, but it seemed interesting to me. I did enjoy using my new deWalt hearing protectors today listening to music while I cleaned the shop and finished setting up my new saw. In fact, the only thing I consider myself well informed on these days is back pain, entirely from experience! I hope yours will ease off quickly. I hope things are otherwise shipshape with you and your family.

Best wishes,
Mike

Humm …wait just 1 minute.. I kinda detect there has been a shiftie pulled here.

May I ask just how Dewalt hearing protectors with digital and FM radio can improve the situation of always having to repeat herself. I suffer from damaged hearing due to high velocity dammage due to military service and I am constantly having to repeat myself to Aurora especially when trying in to whisper sweet nothings in her ear with the intention of getting some action (use your own judgement as to what action actually means)

So picture this here I am in bed with my dewalt hearing protectors on and trying to sweet talk a lady … I am sure its not gunna work !!. (but I could be Wrong)

Next the shims:-

Yep thats looks like the stuff. its a funny situation with riving knives my portable saw for instance has one.
Now when I was helping a friend refurbish his kitched I needed to cut some bench top so I used a thin kerf saw blade with lots of teeth to prevent chipout.
However no sooner had I started to do the cut the saw jambed on me it wasnt until later I realised the blade was actually thinner than the riving knife so it had to go(similar to what madts reported) however i did put it back on.
So I can see why they get binned full time.

Now the electronics:-
If you have exceptionally good quality speakers yes your Son is 100% correct.
Its a bit like a traffic on a multi lane road as a example the more lanes the sooner the traffic gets to its destination and harmonics are good get stuck in traffic and you dont arrive with the same harmony.

The saw:-
I have been thinking about buying a small rip saw as when I arrive on a site to do some work my compound saw cannot rip. It Looks like a good buy regardless of the scam you have pulled.

Who says us oldies are loosing it!

Rob you old devil, I don’t wear them in bed! She is just trying to save whatever hearing I have left. Thanks for the explanation on the speaker leads. I hope I’m learning as much as I’m forgetting these days!

Joe I already tried that. It took me about 5 min. to fill out form and when I submitted it I got a message that an error had occurred. When I went back to the form it was blank. This has been pretty much my usual experience when trying to contact any manufacturers. I call it customer disservice!

Hopefully Mike you don’t need those pieces. I would be skeptical about using metal as a shim being so close to the blade. Maybe find a piece of wood or plastic. Even finding an extra nut or bolt can be scary sometimes cause you don’t know if it will come back and haunt you later. If you couldn’t find it on their parts sheet I would still try to contact them just in case. By the way, it is a nice saw. I have used one like it before and it served the purpose.

My back is better today, and hopefully will be back to its cantankerous self by tomorrow or the next day. So will do a little work in the shop today.

Rob pretty much summed up the speaker wire thing, and I would emphasize the high quality speaker thing.

Regarding speaker wire and such, it is a function of how much volume you are trying to make, pretty much. I use fat wires for high quality speakers that you tend to run at a higher volume. The bass is the amperage hog, and high quality ones produce a lot of bass (talking about full range speakers). The fat wires are necessary for the amps, as I understand it. OK, now you have an expert opinion formed from technology from 40 years ago. You don’t suppose it has changed, do you?

Don’t think I would go the silver route, that seems extravagent. Just use fatter copper wires. That’s 40 years out of date common sense talking… (-:

Since my hearing is good, I just keep testing it. I play loud music over stereo systems at both shops, just to drown out the noise, makes sense to me… (-:

Actually, I do have hearing protectors as well, and for certain machines doing certain tasks, I tend to use them. Otherwise, I hate the devices, and just use my stereo system.

Sun is shining and the day is a wasting, time to get the shop organized…

Jim Always good to get back into the shop. I don’t love earphones, but my new ones with the radio are pretty good. I have tried listening to music while working in the past and normally I just find it distracting. Maybe I have an impaired attention problem or just a simple lack of intelligence, but I do enjoy the radio while doing simple things like lumber through my through my table saw or planing or using any other machine that is noisy and/or requires my large vacuum running.

Joe I would take your advice, but I’m sure I would have to fill out that form again and then get the same error message! Anyway one of the 3 mystery ‘shims’ worked well to line up my riving knife with the sawblade. If they are spare parts I’m so old I probably will never have to replace them anyway! I’m sure the saw will outlast me by many years.

For music I play classical, mostly solo piano. I find that the least distracting. I don’t normally have music in the background anywhere, unless I am cooking, and then I play some shmaltzy New Age cable music channel that is intended to not distract. Cooking is just not demanding enough to keep me occupied, I guess. When I was working, I would turn on my car radio every 6 months to see if it still functioned. That is really my baseline. Playing music in the shop is kinda a new thing for me, probably because I am less intense now.

OK, so now we are both shop music aficionados in our dotage, Mike… (-:

I did get into the shop and did some work today for a couple of hours, and then my back started to tire. It is really doing quite well today, however… progress…

Mike,
While I do understand the purpose of the riving knife, I found it generally to be a nuisance on my Delta Unisaw that I bought in the early 80’s. You have to take it off every time you want use a dado cutter and with different widths of kerfs of the saw blades, it may or may not help. I’ve left mine off and rely on my long bed jointer to get straight edges. I recently had to rebuild this saw with new bearings, belts and pulley. Getting the top lined up again with the fence and riving knife was a real challenge. Best of luck. Great to see you still out there in the shop plugging away. I agree with you about the customer no service thing. I go nowhere with seeking information about how to line up the top correctly. I just ended up doing it by trial and error.

The Old style Unisaw (pre-2009) did not have a riving knife, only a splitter (of several different designs).

I would add that you don’t have to use different thicknesses of riving knives. A thin knife works fine with a full-kerf blade. It’s when you try to use a thin blade with a thick RK that you get into trouble. And yeah, most people threw away the splitter/guard from those saws because they were so poorly designed and in the way for many cuts.

Ken Personally I wouldn’t like to use a table saw without a riving knife, but I can understand the frustration and inconvenience of having to often remove the riving knife to accommodate different blade widths and dates. I would probably do the same a ditch it if I were in your shoes, but that has not been an issue for me so I always use my riving knife. Many of the newer saws have quick release catches for theirs, making it a lot easier to install/remove.

BTW I did manage to identify those mystery parts. They are shims for table top levelling.

Jim I find it hard to find any music I like these days. I like jazz and classic, but a lot of the new stuff turns me off as I find it a bit too experimental or discordant. Fine for many, but my tastes are from another era and try as I may it just doesn’t work for me. I don’t really listen to music much anymore as I seem to prefer the stillness these days. I did however enjoy the earphone music while in the shop. Maybe it’s just the novelty. We’ll see.

I have that same saw but don’t remember getting those pieces you are talking about Mike. I guess I was lucky in that my RK lined up just right from the start. As a matter of fact I have been greatly impressed with that little saw (except for the jerky immediate startup – I wish that had a soft start). My very first cut was far smoother and cleaner than I expected.

You might try to contact the manufacturer again by seeing if there is any way other than that form (I hate those things). I contacted Hitachi about a part that was loose in my new miter saw box and they immediately knew what it was.

What I am doing is playing from mostly classical CD’s I purchased starting in the 80’s, meaning when they essentially all became totally digital. I am not into the modern classical or jazz either. I do play a little old pop music. I have finally ripped a large percentage to my computer, that in turn puts them on my iPhone. So I just hook up my iPhone with its earphone jack to the stereo system in the shop and off I go. That way I have total control over what I am listening to. But as noted, the vast portion of the day, and most time in the shop, is still silence. Must be an old timers thing.

I have a riving knife on my Rigid TS here in La Conner, and I find it a pain to put it back on and a little easier to take off. It is a quick release thing, but by the time you get the guard and pawls on, you have spent a few minutes. Strangely, my favorite situation is my contractor’s saw in Anchorage. There, I use the original guard and splitter that I have hot rodded, the most. I can put it on or off without tools in under 30 sec. I also use a feather board, and the finger saver that came with my Vega fence. I also have the Grr-Gripper system, and the Micro-jig splitter. I always use some safety device at both shops, and keep them close at hand. In Anchorage my big super sled is in frequent use as well, and that is why I like the quick change ability of the splitter. Flipping back and forth between the sled and Grr-Gripper is a good system as well

Here in La Conner I have the Grr-Gripper as well, and a surprisingly good sled from Rockler. So I flip between those two a lot. Just a lot of verbiage to say, figure out an easy safety system and use it. I have been using big saws for 48 years, and I have never had a serious accident with them. Another way to say it is, make safety simple, and you will use it.

Gad zooks, I am a real blow-hard today… (-:

I’ve had only two accidents in my shop since I started woodworking 23 years ago. Both were on my bandsaw, one of the ‘safest’ saws in the shop. The first time was shortly after I got my bandsaw due to plain stupidity and the second time a couple of years later was due to carelessness but just as severe. Both required stitches at the hospital. Since then I’ve learned to be more aware and to think out how I’m going to go about cutting before I turn on the machine.

There is very little we do in the shop that does not have some risk. Some of safety is experience and good habits. Some of it is planning. Some of it is vigilance and intensity of concentration. I had a few near misses early on when I was young, and that probably got me to focus on safety. My job, and the amount of surgery I did probably helped me quite a bit since there are a lot of analogies. One of things you learned in my profession, was to slow down when necessary and make sure you are doing everything correctly. Patience is part of the mix as well, I suspect.

No shop time yesterday, but we were busy travelling around, shopping, and cooking. Today I should get some more done in the shop…
