Hybrid Wedgie Sled
ฝัง
- เผยแพร่เมื่อ 16 ต.ค. 2024
- I have made a new table saw sled for cutting segments used for segmented turning. This new sled is based on the adjustable sled by Jerry Bennett. This sled consists of two fences. It is the difference in angle between these two fences that gives you the angle of each segments, not the angle between the fence and the table saw blade. To quickly adjust the two fences, you make a wedge with the desired angle that can be fit between the two fences. This wedge forces the fences into the desired angle.
I added an extra piece to the sled on the opposite side of the table saw blade from the fences. This extra piece of sled gives the newly cut segment a place to fall and be carried away from the spinning blade.

Sir, I have no idea how you come up with these things, but for the sake of humanity, never stop!! Thanks as always for educating and entertaining.
Do you have all that equipment in your shop ?
Great way to improve a good idea. I really like the screws in the runner idea, that's smart.
Excellent Video. I too have built the Wedgie Sled and I have cut out the numerous necessary Wedgies using a Waterjet instead of a CNC router. I was debating adding the triangular shaped piece of wood to my zero clearance insert just like Jerry, but after seeing what you have built, I might have to reconsider that. Thanks for posting this build. Keep up the good work.
There is a lot about this I like. My favorites are the knobs because they are just a beautiful piece of wood. But the fence or stop and the way it drops the piece you cut onto the sled. That was brilliant. Not just for the safety aspect but for the reduced energy. Bringing it back to you and not having to lean over and grab it. My back is not getting any younger and I just thought for something you are going to do many many times in a segmented bowl. It was a great improvement.
your spatial thinking is top notch to come up with these designs
Your are an awesome craftsman and film maker, thank you so much for all the hard work that you put into your films for making them so enjoyable to watch. You are an inspiration to us all, so much so, that I have decided to start up woodworking myself and have already started to convert my garage space. Many thanks, Simon from the West Midlands in the United Kingdom.
Very well stated.
I just made the Bennett sled this weekend. I Like yours also. I haven't made a stop yet, I did like you did in the video and used the rip fence. Glad I watched your video, I'm making my stop like your design. I don't have a CNC, so my next project is to make a sine bar so that I can make accurate enough cuts on my table saw to get my "wedgie" plates. Nice video and in my case, great timing!
Using the CNC to make precise angle wedges is a real plus. As Frank showed the glue ups are now exact with no extra sanding to make them fit.
+bwillan If you don't have a CNC, just make a bigger wedge. Angles get more accurate with distance. Simple math for one angle of a right triangle, tan(angle)=X/Y. So for 22.5, hit the tan button that you've ignored since 11th grade, and multiply by a big number, say 32, and you get 13.2548. Now just make a right angle triangle with those numbers as the short legs, and draw in the hypotenuse.
***** If I recall, the wedges Frank is making for a given number of segments would be the inclusive angle. So this would require an isosceles triangle where the desired angle would be formed by the two equal sides of the triangle.
If a right angle triangle is used for this jig, it would only cut one angle. Ie a left or right part. The corresponding part couldn't be cut.
Of course, my geometry could be a little off. It's be a few years since high school math.
That's true, but the angle is what we're after, not the rest of the triangle. It's just a whole lot easier to lay it out with a ruler and framing square by using a right angle on the side we don't care about. Using a wedge of a certain angle sets up both fences at half that angle. So a 45° wedge would set up the fences at roughly 22.5° and give you an 8 sided ring. 30° wedge would give you 12 sides. Both those angles are easily attainable with regular drafting tools, but there's lots of other angles to use.
Another neat trick I noticed, since this awesome jig cuts both sides and divides the angles in half for you, you can take 360 and divide by the # of sides you want to get the angle of wedge you need. Say you want a 7 sided bowl, then you need a 51.42° wedge. Much easier to lay out that wedge with math than trying to set a miter sled at 25.71°. You can get crazy with it too. 21 sides = 17.14° wedge. As long as your wedge is accurate, it doesn't matter if one cut is several degrees off, the other cut will compensate to add up to the angle you need.
Just found your video on this sled and agree that the safety aspect is great and will look to duplicating something similar. The video was informative and very well presented and must have taken hours to prepare which is much appreciated. Now all I have to do is persuade 'Her Indoors That Must Be Obeyed ' that the one thing that is missing in my life is a CNC machine. Well I live in hope!!!! Regards John from over the Pond.
I like the second side for holding and returning segments. That is a good addition if you don't have a second throat plate for your saw. I think I'm going to make mine from 1/2" MDO plywood I'm in Hawaii and any composite board is not an option for projects that one wished to last longer than 6 months. By using a quality plywood for the base that is a little thinner I can make deeper segments. I'll probably use 3/4 " double laminated Plywood for the adjustable feces and the wedges I have a fair amount of that as scrap from a display case project.
I think you're exactly right when playing that close to the blade.
Frank, Did you use the same dimensions for your sled as were in jerry's instructions? You pivot points look further apart.
Ken
Very innovative thinking. Love the sled. So nice meeting you in Atlanta.
Brilliant upgrade to Jerry Bennett's already brilliant design!!
so much cleverness in one video...that´s awesome!
I would not be surprised if other aspiring wood workers agreed with me that a video that showed your process of drawing CAD files and aligning/calibrating the CNC machine would be really awesome
I've used the same threaded inserts for making tamper handles (for espresso machines) and found that the brass and the steel have a tendency to bond together over a period of just a few days. This causes the threaded insert to unscrew from the wood instead of the handle from the bolt. Needless to say, I highly recommend that you glue the threaded insert into place, or use the (more-annoying-to-install) zinc plated variety.
+Right. How do I make that? Thanks for the info, I will watch them over time.
Frank
Once again you have opened your mouth and a cornucopia of knowledge and Craftsmanship has poured out
Thank you
All the best jigs are the ones that seem so obvious after they are built. Great video Frank!
Every time there is a shot showing your CNC in all its glory I start smiling .. I just noticed that !
Great job Fred. I made the traditional wedgie sled, but I have a problem. I really don't want to be around the blade, (for safety reasons), and I wonder if there's a way to fix the problem, without making another sled. I have made the traditional 12 segment sled, actually the way you have done on your demonstration. The whole cut process is done on the sled, and when you pull it back, after cutting the piece, you are well away from the blade and you can remove the pieces without difficulty. However, when I made the wedgie sled, I only took the end of the sled to the blade, so the blade will cut the piece, but the piece will be left on the table, which is what I don't want. Would I just glue and extra piece to the end, then attach the fence to the perpendicular end, and then cut thru with the saw blade? That way I wouldn't be cutting thru any screws, and I could cut thru the glue slot to allow clearance for the blade?Thanks for your input,Tommy Schutz
I liked the knobs!
Also, wanted to give a compliment on the video you shot for Mac Sheldon. It is by far the best video ever shot on Hybrid Pantorouter...:)
+Михаил Макаревич Thanks
Looks like this should work out very well. The gluing each half and sanding was hurting your patterns so this looks like it'll be a big help.
nicely done sir,just love the way its narrated as well,safety first well done
Frank love the videos, have watched them all now. Video quality is fantastic and your explanations and care to detail for the viewer pulls you in! Fantastic look forward to more.
Have recommended to all my wood working friends in Scotland!
+Giulio Lanny Thanks!
I really love how the saw has been taken out of the angle equation. It makes so much sense. Now making your angle block jigs was pure genius! Will save so much time.
As always, fun, smart, well done. The stop jig is a excellent and clever safety addition. Regards from Brazil.
Your the smartest man alive! Time, Talent, Patience.
Gee whiz Frank, you have an incredible shop--color me jealous!! I am just getting a little deeper into woodworking, I just ordered a table saw--Grizzly, a bandsaw-Rikon 10-326, a Supermax drum sander, a Rikon helical planer and a few odd bits and pieces. Mu question for you is would you make me a sled like this--I seriously lack the skill and a lot of tools to do one--I would pay you what you said for it.
Oh, and I disagree with the other poster who said your CNC is offputting to viewers, it is awesome to see someone utilizing one, and makes others (me) dream of what he should add next to his shop.
Thanks for your consideration--oh and yeah, awesome 'graphics?' with the wheels and arms moving around by themselves--really cool!
I'm always amazed at how well you can take an already good idea and make it even better and, more importantly, safer!! I wonder if a sled on a sled would work - basically, a small sled on the cutoff side that rides in the main sled body so, after the piece is cut, you could push the secondary/cutoff sled forward to eject the piece away from the blade. It's probably over complicating the solution. Great video, as always!!
Very nice addition to the wedgie sled. I spend a lot of time thinking about that “momentary lapse” that leads to touching the blade. I have a lot of time at the saw to think about it as I cut 1440 pieces or more per project.
This will definitely get integrated into wedgie sled 2.0.
My fingers will be grateful because it’s honestly not a matter of if, but when.
Thanks Frank. Really appreciate you keeping the part where you struggle with the clamp, since I always feel like I have two left feet (hands maybe?) in the workshop.
Great video, hope you feel better.
It's so cool to see how you continue to refine your techniques Frank. Thanks for making these videos.
I love how much you've been integrating the CNC machine into your projects, its' really become a useful tool, more than a "toy" to say you have it. and jigs and sleds make the world go round, huh?"
The fixture is very well thought out and well made. Liked videos. Good Luck To You. Like!
Those are some good upgrades. I think I may revamp my wedgie sled too. Thanks
Ken
This is so cool. That CNC is really coming in handy.
+William Ellison
That's what I thought too... I wasn't the least bit envious until he held that almost-finished knob up to the camera.
+David Smart Same here! Franks way of using the cnc makes me want one, was not as keen before
Always enjoy your videos. You are an excellent teacher with plenty of patience and creativity. Keep on making them please!
GREAT video Frank. The modifications you made are spot on. 8:59 "it only takes one lapse of concentration" and your day is ruined.
watch your sleeves on the table saw work. real nice sled Tom
Very ingenious and, as always, great videography! Thanks for sharing.
I love all the upgrades. Would you mind sharing the CNC file to cut the base! I look forward to more of your video's!
Thanks for all the time you put in to share your knowledge with us.
I love the addition to the original and am going to use this without a doubt. I am always worried about the cutoffs being so close to the blade
I like the additions you made to the Weggie Sled. My attempts with the sled were ackward, yours looks safer and more efficient. Thanks for sharing .
"One little lapse in concentration" -- I think I will make a sign and hang it in my shop. Another great video.
1 word... Sawstop (if you can afford it) i cant afford to lose a finger tho 😳
+Joseph Lareau
SAWSTOP...exactly...I luckily have 2 SS's.
Thank you Frank. I just re-configured my sled with you safety features.
I spent weeks getting my sled set up to get perfect twelve segment rings. You're starting to convince me to build one of these now, Frank!
Creativity on high level. Thats a goal to make a sled like this in the future. Have a nice weekend. Jan from Norway
Great vid as usual, Frank. I love all the extra effort you put into the animations and illustraions that make it all so informative and entertaining. Scott
Have you thought about cutting little stairway-patterns in the holders you have on the CNC? Would that make it easier to clamp different thicknesses of wood without having to angle the inserts too much and put stress on the bolts? Great video as always, too.
+Leon Overweel I have one step cut in them, I like the idea of multiple steps.
Beautiful work as usual. I bet this could be combined into a "master sled" for those who have limited space or materials for jigs too.
Really neat - and impressive that you are getting perfect angles right off the jig! One thing on the stop you designed - if you had the screw that holds the position serve to also tighten the rail in the track, you wouldn't have the issue of it sometimes getting caught and dragged along with the sled. Not a biggie, but something you could add at some point if you wanted. But yeah, great video and I'm looking forward to seeing this thing in action!
great job on it. It got me thinking if you linked the two arms together with two peices, that go from the bolts in you radiused holes to a single bolt in its own strait slot between your adjustable arms (running perpendicular to the saw blade) it might eliminate having to cut degeed wedges. whats your thoughts?
Great use of the CNC as another tool in the shop to help make jig parts and get accurate pieces made. That is why I have one too.
Great video Frank. It would seem to me that you could flip the piece in place after every cut to achieve the opposite angles without needing one of the arms. I may be wrong though
+Kuria Kinyanjui Then the angle between the blade and the fence has to be just right. which is do able just a little more effort to set up.
Thanks for a very informative and entertaining video. Nice shop, nice work, great video and animation. Who the heck didnt like this!
Nice Frank, enjoyed meeting you in Atlanta really enjoy your videos
Why not use the CNC to bevel the offcut-side of the sled? That would allow the segment to fall away.
By the way, for cutting very small pieces, I make a tube that fits a shop-vac hose and put a piece of hardware cloth screen a few inches inside the tube. Then the tube is fixed next to the sawblade, so that when the piece is cut off, it is sucked into the tube against the screen. A number of pieces can be cut before it's necessary to empt the tube, or you can extend the tube off the sawtable and put in a tee with a collection container.
Great job! I was wondering if you found it easier than your original setup. Wouldn't you be able to create the angle wedge for your original table saw sled to create the angle? Do you find this method a lot safer? I'm sorry for the questions. I'm just very curious.
Also, everything I know about segmented wood turning i've learned from your videos. Thank you for posting them... I always look forward to your work!
Well thought out upgrade to a good design and a good example of a practical use of the CnC. Thanks for that!
Very cool work Frank! I like the updates that you made.
hello sir, I really love your video and workshop. thank you so much for your help and dedication
I love the safe approach you're taking to a task that might be easy to space out on. Great setup!
Love your modification that makes it a complete sled! However, it looks like you might add a tensioning screw to your t-slot on your stop.
Great video, I clapped when the final sled assembled itself and the fences wiggled.
Nice one Frank. I was wondering when you would pick up on Jerry's segmentation sled being a how you do a bunch of segmented turnings. It was nice to meet and chat with you in Atlanta. Glad you could make it down there. Keep on keeping on.
Wow, his jigs are nicer than some of the projects I've done
I think that an often overlooked benefit of improving safety is speed. The fact that the action to move the piece off the sled happens away from the blade means that it requires less time and can be done without the added motion of carefully reaching near the blade
It seems like the fence on the big table saw isn't quite long enough to cut large sheets of plywood. Can you not swap it with the yellow saw's fence?
Nice sled Frank, thank for the video. As always, excellent editing.
Good thinking on adding the extra parts. I made the sled also and have had some small pieces turn into rockets across the shop. If you decide to sell the homeade wedges, let me know I'll buy some.
Watching your videos is very relaxing for me. Thank you!
Hi Frank. Did you seal your segment sled after construction? I built one like you made here but don't know whether to seal it or not. Awesome video. Thanks
Aha! Yep, you gave me another 'aha' moment Frank. thanks!
Nice work as usual. I enjoyed meeting you at the Atlanta show. Your video was very helpful, I too had just completed a large Wedgie Sled like yours but was stumped on the stop but not anymore! Awesome work and Thanks again!
Very cool Frank. Thanks for sharing with us.
The stop might be helped by a couple of 1 1/2 upright pieces about in the middle to prevent the stop from any lateral motion. Or did you put a pin in to stick up into the slot? I couldnt tell for sure. Wonderful video as usual and we all are envious of your CNC --Not to mention the space to have it! :) Keep them coming please
Nice I just made one of the traditional wedgie sleds and I love it, I made the zero clearance wedge slide and love it. Your cnc nut handles look really nice and the sled looks like it works great.
+Erik Anderson Cool, thanks Erik
Your stop-go animation looks really smooth lately. Especially when it looks like your router is moving on its own ;)
You always know how to take a great idea and explain the hell out of it! Awesome job Frank!
Great idea that considers safety! Only disadvantage is that most of us don’t have the hi tech equipment to make some of the pieces. But, where there is a will, there is another way…..just slower to accomplish. Thanks for sharing!👍👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
Dear Frank, thanks for sharing your take on making the wedgie sled. The safety features are the best I have seen so far. Have you gone ahead and made some wedgies and then done any segmented turning? I’ve only recently discovered the concept having struggled with end grain turning. Turning hollow shapes with near continuous long grain would be such a dream run. Cheers and thanks again for sharing your talent and amazing equipment.
Great video as always! I aspire to your level of storytelling. Looks like a great design Jerry Bennett came up with and I love your modifications to bring the cut off back for easy removal.
thank you Frank... best regards from Colombia
Thanks for this Frank. I made my first wedgie sled today and incorporated some of your ideas (Actually all of them :-] ).. I appreciate you sharing your knowledge and clear presentations... Now I have to make some triangles to compliment my lone 30 degree Globe square. Stay safe....
An excellent video Frank, the additions you have made a great idea, into an even better one :)
Kudos for giving the originator the credit too, for giving you the initial inspiration, it's a great shame that more people don't seem to do that, instead of trying to make the idea their own.
Cheers
Mike
+Mike Waldt Thanks mike, I agree. We're all standing on someones shoulders
For the main sled, did you just use the normal dimensions that segeasy suggests on their site? Great work
Neat sled Frank, thanks for sharing.
Seems like you might want to use that rail adjusting trick on your stop block, except perpendicular to the table and maybe at both rail ends. That way you can lock the stop block in place and not have to fuss with it while cutting.
Just a thought. ☺
This is a great build, thanks for sharing! Also, sorry I missed you in ATL! Hope to see you next time :)
Very nice sled. The padouk knobs really set off the MDF.... ;) lol Thanks for the video.
Nice, very simple and clever
Could you have used the same hole and slot to lock the length stop to the miter slot so it would not move. I've seen it used to lock feather boards down. Love the video and thanks for sharing.
VERY GOOD TIPS!!! 👍🏻
Very nice jig, Frank!
Very well done I like the idea a lot and yes as a process worker it is easy to have a momentary lapse and forget and in this case loose a finger
Very nice Frank !
Frank for that adjustable stop on the left side maybe you could make a strip to lay in the slot on the saw that has a clip on the end of it to prevent the stop from being pulled forward with the sled.
Nice video and project Frank. You always deliver a great video.
Great video and excellent safety idea, Frank! Thank you!
