Dave: I need to comment on you presentation. In my opinion, you are one of the best if not the best online video teacher that have seen and and watch a lot of "how to" videos. You must be a teacher or a natural. You presentation is precise, clear, to the point and very important, it is presented in bite size bits of information. Your visual is also excellent. Thanks for a great job.
I just made my first wedgie sled yesterday. I cut a strip of 2x4 into 16 pieces and they went together perfect! It just couldn't get easier.Excellent videos and excellent idea. I did modify the wedgie sled a bit from your original plan. When I cut the rails I made a single cut on a tables saw so that I had a 24" x 2" piece and then cut it in half. I then drilled a single whole through one end same as you but on the other end I cut a slot in the middle by dropping it onto my router table with a fence. Slot is about 4" long. On the base of the wedgie sled instead of cutting two holes and two arcs I just cut two slots using the router table with a fence again. Now I can adjust the distance between the mouth of the rails as well as getting the angles set correctly. I didn't have to cut any templates or route any arcs.Outstanding concept Jerry! Thank you again for sharing and making segmented turning so much easier!
New to segmented turning. Just learning. I have a CNC machine, so my plan is to cut the wedges once I learn the angles and sizes they need to be. Thank you again.
This is one of the best instructional videos on UA-cam. I'm About to venture into segmented turning and have ordered my wedgies. I will certainly be building this sled as soon as I can assemble all of the parts.
Hi saw the video on UA-cam for the first time to make the sled I proceeded to make it and use it I have to admit I was sceptical about it being accurate as claimed but I was very pleasantly surprised it's amazing and works a treat Thankyou for the video and will certainly use it for all my you segmented work John Bisby Yorkshire UK
I just finished making the sled, thank you for this. The sled has taken my segmented turning to the next level. Perfect segments the first time out, awesome!
Hi Dave! Great video! I just wanted to say that I had a couple of "alterations" though... First, as I don't have a plunge router, I let my drill press do the plunging for me, then dropped in the router with the template and the router bit slightly extended. Works well, for anyone else who may not have the plunge capability. Next, I decided to use a regular 1/4-20 bolt at the pivot point. I noticed as I worked that the carriage bolt was already causing wear in the pivot hole, so by changing the bolt, the pivot hole has a smooth shank to rotate on. Other than that, no problem! Thanks again for your video, first rate!!
Awesome video! You explained everything in detail and showed every step. Thank you for making this video. All I need now are some wedgies. Thank you again
Dave, Excellent video. Very thoughtfully crafted, and flawless presentation. Using a 30/60/90 triangle I made a perfect 12 segment ring. Easy breezey. Thank you, Ed W
Cheers Dave for posting and of course a big thanks to Jerry Bennett the designer. I'm off out to the workshop now to get on with the build.The instructions are in-depth and precise, thanks again for the post and sharing, regards and best wishes to you both (Jerry and Dave).
Hi Jerry... or anyone. I don't know why but I was expecting you to set up the sled on the other side of the blade? Any reason you set up on the right of the blade versus the left? And, as many have said here - super clear an concise film - much appreciated.
Hi Jerry I got my wedges from you yesterday Thank You! I’m new to this and I’m going to build a wedge sled soon but I have a question How do I figure out how long to cut the segment? I’m not good with math and the biggest ring I can turn on my lathe is 12”. Generally I will make rings 10” in diameter. To start. That will give me an idea how long to cut. If that makes sense?!? Thanks again. KB
It seems to me that when you marked the maximum lines for routing the grooves that you used the inside edge of the fences. Shouldn’t you go at least 1” beyond that so the groove goes the the position where the bolt will be when that inside edge is on that line plus a little
Fantastic presentation 👏 I am ready to give segmented bowls a try. This sled is my next build, nonetheless I have a couple questions; How do I determine the angles to create the wedgies to slide in between the guides? How do I determine the width of each segment? Is there a formula? If so, what is it? Ho
Hi When making the sled is it okay to have a larger gap between the fences so you could use 3" timber or larger. Alternatively is the sled still accurate if you cut the wedges using the outside of the fences which would enable you to cut bigger wedges. Excellent video and concept. Many thanks Gary Smith
It is but you must use a spacer to insure the wedgie engages the fences fully. Cutting outside the fences is not safe. The table saw is not your friend. It will bite you.
Hi Jerry. Great video presentation! I'm building a wedgie sled right now. One quick question. The screws that you used in the slots....they were the same size as the ones that you used to attach the guide to the bottom of the sled, correct? If so, hence the need for 7 not just 5 #6 x 3/4" screws for the project. Again, just checking.
Thank you for your prompt and helpful response. I am currently using my bandsaw with the sled to cut my wedge segments. I find this is not so aggressive as a bandsaw and todate my first ring came out perfectly without any sanding etc. There are two questions, i) using the outside of the fences when you need wider segments - do they cut the angle accurately still, and b) would you agree that using a bandsaw is considerably saver than a circular saw, albeit any machine needs to treated with respect. Thanks again KR Gary Smith
The bandsaw is not going to spit segments back at you. In that regard it is safer to cut outside the fences than with a tablesaw which is not safe to do at all. As you know the bandsaw lulls you into feeling it is safer than it actually is.
Just a question/comment, when you say the only thing that determines the accuracy is the angle of the plastic wedge - this isn't quite true. One cut is on the inner face of the two 'fences' the next cut is on the outside face of the other fence. This means that that fence must be precisely parallel or it would introduce errors. i assume for thin stock you could use both inner faces. Is this correct or am I missing something? Great video though.
Gentlemen, just built my second wedgie sled. Glued bowl rings yesterday, great fit! Today, my angles are off and I cannot figure out why! The angle between the arms is 45 degrees=8 segments...help...
I see you built your sled to ride on the right hand side of the saw blade. ( Looking at the saw) Is this important or can I follow these instructions and mount it to the left of the bade? Cant wait to start building this and take my turning to the next level. Thank you for your time and the video.
Great videos and thank you for sharing. One question, your saw blade seems higher than it needs to be. Is there any problem with me running mine just above the surface of the wood?
+Tom C Segmentology is about the science of cutting segments as accurately as possible. I want the cut to be as vertical as possible. This minimizes errors that may exist in the alignment of the blade. There is another consideration. We are cutting small segments. You want the teeth to be in contact with the segment as little as possible the moment after the segment is cut. The horizontal velocity at the top of the blade is around 148 miles per hour, and having a cut segment still in contact with the teeth with the blade low, is not desirable. With the blade high, the horizontal velocity at the top of the segment is 90 percent less, and contact time with the teeth the moment after the cut is small. Always use a blade guard for your personal safety. It is not shown in the video so that we can see what is going on. My guard also has dust collection.
I have a question. I made a wedgie sled and it works great. Except. Say my ring width is 3”. Only a 2” piece will fit on the inside of my sled. Can I butt the piece up to the back side of the lower brace(since the sides are parallel)?
Dave, do the wedgies have to be perpendicular 90 degrees to the saw blade? I noticed in the video and Jerry’s videos that their is no accurate location for the wedgies. Thanks.
Great tutorial! Half way through building my sled now. Quick question: did you find that a certain kind of double-sided tape works well when attaching the template to the router for the swing dados? I'd want to clean up my router afterward and get all the gum/tape off. Thoughts?
@@JerryBennettArt Yep, in fact I used some mounting tape I found at Lowes which worked fine for attaching the template to the router ... but since it's about 1 mm in thickness, it'll mess with the height of the 3/4" strip on the underside that fits in the miter slot. I'll head to Woodcraft.
I purchased the entire set of wedgie's. I am not able to get totally accurate wedges. I have made sure my blade is square, my arms are square and flat but have not been able to get perfect results. Of course the wider the sections the more problems arise. Any ideas what I am doing wrong?
Hi Mike, my guess is you have spaced the fences further apart. It is necessary that the Wedgie engage the fences completely. You must use an accurate spacer with the wedgie to accomplish this. You can get complete help by going to info@segeasy.com. Jerry
Alright Jerry, I've got my Sled built and along with your 16 and 32 wedgie I've started cutting my segments, but I've run into an annoying problem. I keep ending up with a misalignment on the outside edge of my ring halves. What do you suggest I do to correct this issue? As a side note, I've found that the substitution of the carriage bolts with toilet mounting bolts to ease the issue of the arms sticking when adjusting the angles..
I just ordered a 16 segment Wedgie. The price for the wedgie is ok, but your shipping is pretty outrageous for such a small item. $12.99 for the wedgie and $11.72 for shipping??? What's up with that?
Great customer service! I just received an email from Jerry indicating that he was able to give me a better postage rate and he refunded some of the postage. Wow! That was fast! I wish other companies would take a lesson from this! Thanks Jerry!
Wow! Jerry is awesome! I just received my Wedgie! Super fast delivery. On top of that, I was also surprised when I opened the package. In addition to the 16 secret wedge I ordered, I also found a complementary 30 segment wedgie! A great big "Thank you"! Will be ordering more wedgies soon!
Informative video, Not a biggie, but you claim "the knobs are 70mm in diameter but you can go no larger than 1 1/2 inches in diameter". Ummm 70mm is 2.75 inches and that is definitely over 1.5 inches. 1.5 inches is 38mm. So I think your math and or measuring instruments may be off quite a lot. I think it should also be mentioned that you want the long edges of your fences to be perfectly parallel. That way you can use either side of the "fence" when cutting your wedges. Thanks for taking the time to post and share your video.

Just got my wedgie's today. Can't wait to be able to finish my sled, waiting on knobs. Then get cutting, thanks for the video.
Fantastic presentation 👏 I am ready to give segmented bowls a try. This sled is my next build, nonetheless I have a couple questions;
How do I determine the angles to create the wedgies to slide in between the guides?
How do I determine the width of each segment? Is there a formula? If so, what is it?
Ho
It is easier to place straight slots and use t track for the arms to slide on. That's how I made mine and it is fantastic!
Hi Rob, I have one as well. Works great!
Did you set yours up to the right of the blade because you have a left tilt saw? I've seen others use the sled on the left of the blade
Thank you so much for your instruction time and doing this in such detail. This is most helpful for me and many others watching I'm sure!
Brilliant, thank you
Never thought I would pay to give myself a wedgie

What is determined to make the segment width not the length ? There must be a stop on the other side of the saw blade. What do you use ?
Thanks for the vid. It might be a good idea to harden the holes & slots with a coat of CA glue.
What is used to determine the segment length?

Of course you need accurate fences. It is not difficult to do. As to using the inside of the upper fence, it is not safe. I do not recommend it.
Good presentation . just one question did you leave the double face tape on or did you remove the tape once you had the 5 screw holes pre-drilled?
+Dick Wiebe It does not matter as long as the tape does not interfere with the sled sliding along the table saw.

Go to www.segeasy.com
There are tutorials and plans for many different things.
Thanks for the great video. I am going down to my workshop now to make one of these. How do you cut the wedgie? What degree?
Maryke Dykhuizen just math. 360 degrees in a circle.
I don’t understand the difference in the open & closed wedgies for sale. Obviously I’m new to segmenting.
Take a look at www.segeasy.com
everything is there
Dave, do the wedgies have to be perpendicular 90 degrees to the saw blade? I noticed in the video and Jerry’s videos that their is no accurate location for the wedgies. Thanks.
Wow... very good video about this topic!!!
Where to buy the wedgies? Or is these not something that is for the public?
Thank you for a very good tutorial. Much appreciated.
Im terrible at this kind of stuff...🤦🏾...does anybody sell this sled because i want to purchase it
is there a reason why people use MDF instead of particle bord or plywood?
It is stable and economical.
do you use open wedgies or close one for this jig
You can use the Wedgie sled to make segments for open or closed construction.
I've seen some other wedgie type sleds with the top inner fence cut at an angle, any idea why ? Is it for wider wedgies maybe.
Jerry , great job. how can I get the wedgies.
+James Martin sr.
Thanks James. Go to www.segeasy.com
for the Wedgies.
Make you own. 360 divided the number of segments you want to use then divide by 2 to get the angle.
Great job Jerry.
Can anyone buy this sled, block stop and wedgies from you as a total package?
If so, how and how much for the Complete Package?

@@JerryBennettArt Hi .. I was wondering the same. I'm assuming 35-38mm is about right? 1/4x20 thread.
Don't the wedgie "guides" have to be perfect?
