Nice work BUT, what about using goggles, ear plugs for noise supression, using a push stick on the table saw, no dust extraction. You seem to be very experienced at what you are doing but you never know when an accident is going to happen. Doesn't send out a very good safety message.

[@CogentConsult]

I like your work, it’s very precise! Since you work with your fingers far too close to the blade, I suggest you purchase a SawStop table saw. This way if your fingers ever do accidentally come in contact with the blade, you’ll only get a scratch, and you won’t cut your fingers off.

[@jerrysmigiel7998]

Nice job.

[@multibusa]

A great well thought out jig, I will surely be making one for myself. This isn’t bashing you or trolling but If I may say, I made an observation at the beginning of the video watching you push a board through your table saw without using a push stick. You pushed the off cut through past the blade on the right hand side, then you you reached over the spinning blade to lift out the off cut. This is hugely dangerous which I’m sure you already know. There are 3 immediate things things that come to mind why this practice is extremely dangerous. 1. The more you have cut boards/timber without a push stick you get complacent because it’s become second nature to you, this is where one day, while in auto pilot, you just for a second think about something else followed by looking for your missing fingers. 2. Once in a while a narrow off cut on the fence side can jam making you inadvertently push a little harder, the next thing is your looking for your missing fingers. Those new to woodworking are not always knowledgeable about the dangers of woodworking machines. So they see you pushing material through the saw with just your fingers and no push stick. Being novices they probably won’t know the dangers and may well have an accident followed by them looking for their fingers. There are so many experienced woodworkers that loose their finger’s. You should really be seeing an example my friend. Other than that a great video.👍

J-woodworking목공일기 No problem, thank you for taking the time to post such a well structured easy to follow instructional video. I’ve been looking at some of your previous projects, which are equally impressive.

Why did you leave some space between the opposite fence to the router plate at 02:20? Wouldn’t that space add to the width of the dado and make the dado too wide for the board? Great video by the way! I’m new to woodworking... I thought both fence should be touching the base plate on both sides?

Great video and I really liked how you built the jig THEN used the router to square the track for the dado cuts. One question... at 2:16 in the video it looked like you left a little space between the router plate and the edge guide on one side. Is this what you did or did I not see it correctly? If this is what you did can you please explain why? I would think both sides - edge guides - should fit snug against the router plate. Thank yo very much - I plant to build my dado jig in the same fashion as you did... Larry

[@thomasstock1985]

it's for the width of the saw blade. He cuts the jig in half and then puts both parts against eachother. There wouldn't be room to fit the router plate otherwise

[@EEEZSolutionS]

Thanks - yeah, eventually I figured that out :)

[@CrustyCurmudgeon]

I see some others commenting about safety on the table saw, and I'm gonna add to that. Its frightening to watch your table saw technique. No guard is fairly normal, but no riving knife, no hold-downs to prevent/protect from a kickback, no push stick? If that's your shop, you've obviously spent a lot of money on equipment. Spend a little on safety before you lose something you can't replace. And why the crosscuts by raising and lowering the blade? Weird

[@constantinosschinas4503]

this jig would work better and more accurate with a full round router plate. also, if used with side stops and longer sliders, it can be a very handy adjustable medium to big pocket jig.

[@jm1964jmir]

hello good afternoon from Spain, I have a question about your project, and when you remove the base of the router and place it in the guide, the straight part touches the side of the guide but the round part looks like you leave a few millimeters and I don't know why. Could you clarify it for me? I do not understand. Should I touch both sides (round and straight) on both sides of the guide? Thank you very much and greetings.

[@j-woodworking9573]

A few millimeters is the same as the saw blade thickness. After sawing the center of the guide, two parts of the guide can fit the router base inside. Thanks for question.

[@omgname]

Hello. Just wondering then why didn't you start with 2 pieces to begin with? That way you don't have to guess the thickness of the saw blade. I also have a question about the operation. If you measure the insert piece, then you cut a perfect mortise, it doesn't make sense. Lets say, you piece is zero thickness, your mortise width would be the diameter of the bit. So your way seems like the cut width would be the thickness of the insert + the diameter of the bit. I am confused. Please help me understand. Thanks.

[@junkmail4613]

14:10 as a friend, it is great NOT gteat , But for not knowing our language, you did "great" As a FRIEND, I offer you this below, That I have seen nowhere before, but I offer it to you because I thought of it while watching your video. If, on the underside of your router, you had "two thin flat sliding pieces of wood", with sliding slots, on screws you could adjust and tighten in place, you could adjust those sliding pieces of wood, to fit any router bit diameter. Fat ones or thin ones, big or small. with the diameter of the router bit as a guide the outermost edges of those "two thin flat sliding pieces of wood", would always be the proper distance from the guiding edges you just built in this video. It would work perfectly. Every router bit, thick or thin, big or small, would fit perfectly between your guiding rails, because those "two thin flat sliding pieces of wood" would always be exactly the distance between the outside of the router bit and your guiding rails. Once achieved, it would be perfect.

Never saw anyone use a table saw as a chop saw. Plus, i would have used a push block while ripping in the earlier part of the video.

[@randolpharends5755]

I have been usin a table saw for over thirty years. This I cut myself. Don't get too comfortable. A mistake on the table saw is not forgiving. You will cut yourself when you make a mistake. Use a push stick or block and adjust the height of the blade to the thickness of the piece. This time I kept my thumb, I don't want to find what will happen next. Safe carpentry my friend.

So u just use a straight bit with no collar?

[@j-woodworking9573]

Yes, just straight bit. Thanks for watching sir.

[@avenidagarcia2373]

sorry I do not understand, you cut the base of the jig to fit the base of the router, you then cut the jig in half so you can use an off piece as measurement, however, if you do this now the jig is stretched and the router for it to glide straight it needs to be rotated, in the video you only cut in one direction. Was this part left out of the video or am I missing something?

[@bradscopegems]

I agree with this question. What about the routing of the other side of the dado slot? You don't show it, and this makes me suspect that this jig is useful only if the bit cuts a slot of the exactly correct width in a single pass. Please explain how you cut the side of the dado slot further from you.

[@jamesvibert2118]

@@bradscopegems I don't believe it is necessary. That pass is only for the bit width which is accomplished in a single one way pass. You size the dado slot by setting the jig to the width of the piece, tightening the adjusting knobs and then routing both sides for an exact slot dado. That single pass must be done with a bit that will be no bigger in diameter than the narrowest dado to be made. And, that bit size must be used in all future dados cut with the jig. IMHO

[@bradscopegems]

@@jamesvibert2118 There are two disadvantages for this design. First, the jig works only with one width of bit. Secondly, because the bit is guided by a different fence when cutting the second side of the dado slot, the router base has to be either perfectly circular or with equal flats exactly symmetrically arranged on each side. A lot of routers have a big cutout on one side of the circular base, which is designed to go against any fence: your jig does not work with this type of router base. Using a template bit instead of a plain bit means that the same jig can be used with any type of router base and with any width of bit, since fences on each side are not necessary.

[@jamesvibert2118]

@@bradscopegems I agree on the bit size needs to be constant as I mentioned. The video shows a slight gap between the base (which has a flat on one side) when assembled. After the cut into two sides I suspect the base would not fit between the sides unless opened slightly. This would then have both sides of the router base tight on the fence side being used in that cut. I have about a dozen routers in my shop with only a third having the flat side on the base. Most have round or custom bases. All, other than trim routers, have directional arrows drawn on them as the bases on routers are not necessarily exactly round and cannot be counted on to be perfectly centered. This is not my jig, I, like you am a subscriber.

[@bradscopegems]

@@jamesvibert2118 Thank you for your clear explanation. I will follow your design, since I like the idea of using ordinary bits rather than template bits, but here's an idea: I will screw a metal plate to the base of my Bosch POF 500A router so that it eliminates the cutout and has one accurately straight side at a distance from the centre of the bit a few millimeters more than the radius of the circular edge of the original base. I will always use this side to hold against the fence. This has the advantage that I will be able to cut all the dado widths I want using just the one 1/4 inch width bit, and since the two halves of the jig will then be identical, I will be able to cut dados only slightly wider than 1/4 if required. There will always be a gap between the unused side of the base and the unused adjacent fence, so the base will never stick, even if the two sides of the jig have been set by tightening against a 1/4 inch sheet. Does this make sense?
