The auto vac switch with delayed on-off is a problem if you are using a tool intermittently, like a miter saw cutting multiple pieces. It turns the vacuum on and off every several seconds each time you finish a cut and position a piece for the next cut, which is not good for the vacuum motor. Whereas with the remote switch, you leave the vac on while you position your next piece to cut. Same for using a detail sander, where you are going to use it intermittently as you move to different parts of what you are sanding. I prefer the remote switch, with a few controllers placed around the shop. And as others have noted, if you have a decent sized dust collector or large shop vac, and are using a high amp machine like a table saw or 3 hp router, you are likely maxing out the 20 amp circuit, which even if it doesn't throw the breaker, will still do damage to the motor.

why not just line up the fence with the end of the table and fasten it to the sled? thats literally square

Thanks for posting the video, my sled is properly squared now! A couple of items I learned doing the adjustment are: 1) when making the adjustment and drilling a new anchor hole, place the sled on the table saw so the runners are in their slots before you clamp down the fence . The first time I did the adjustment the sled was on my workbench and the runners became slightly out of alignment and there is no margin for error when this occurs so I had to drill another hole. 2) The calculator is designed to provide the error adjustment when you cut your piece on the left side of the blade which I think is the most common way people make cuts. However, if you cut from the other side of the blade I believe the result would need to be reversed to adjust in the opposite direction. The video shows cutting on the right of the blade though however the second video covers this issue - I think there will be a change to the calculator to indicate which side your cuts were made on. 3) this is embarrassing, but if you have a few holes you drilled for adjustments, keep track of the ones that are no good. I had three holes (initial hole, a second hole that I drilled but didn't have the runners in the table slots, and then the final hole). I took out the screw from the third hole to counter sink it further and do some sanding and then I wasn't sure which hole was the third hole. Luckily I already had put in my additional screws to fully support the fence so I didn't lose my alignment.

not sure about safety issues, but i think the problem with cutting strips on the tablesaw is that the kerf is so wide. it turns quite a lot of wood into sawdust. a bandsaw, on the other hand, has a much narrower kerf and it would give you more strips from the same piece of wood.

Really neat, Thank You!

what thickness of wood do you take please.thanks

This is truly amazing! I'm so glad that I found your channel and saw this video, thank you so much brother! You definitely have a new enthusiastic subscriber how much appreciated. I hope you have a Merry Christmas my friend

Is this Mike birbiglia

Is the pivot length of 22" , the distance between each screw? Thanks.

Can I use the calculator with cm? Metric.

You mentioned that the pivot was 22". Was this the distance between the screws initially, or the distance after moving the screw based on the first calculation? ..or is the 22" the distance from the stationary screw and the point of the block that's clamped down, with the .014" spacer?

@BikeCityWoodworks thanks for the lesson. I want to try it on a scroll saw. Do you have any jigs for doing it that way?

@BikeCityWoodworks thanks for the lesson.

@BikeCityWoodworks thanks for the lesson.

@BikeCityWoodworks thanks for the lesson

Your 5 Cut-Calculator is Absolutely DA BOMB !!!! Thank you so much, for it.

You're doing 5 cuts. Why do you divide the difference between A and B by 4 and not by 5?

Can this be used for metric?

Im building mine TODAY thanks I will pass on the idea to others as well….

I’ll have to make something similar 👌 thanks for the video

New sub, gonna build that portable dust collector! Thank you

excellent , well explained Pete from New York

I like it. Thanks!

This is brilliant, thank you! And thank you for including metric for us Australians!

What's interesting is I saw this video when you first put it out and I thought it was a great idea. Now, I'm trying to come up with a similar idea for clamping up frames for some Kumiko work, and this is a perfect solution. I just have to add another cleat at 90 degrees and it will work perfect. Thank you a second time for the great idea.

These are two separate things for two separate purposes!

I’ve got to say thank you for the calculator. Made the job of a sled so much easier to correct.

I like it.

All I have to do to turn my dust collector on is say “Alexa turn the Vacuum on” I used an accessory plus that works with Alexa.. I have that biatch in my shop and she comes in handy for.. and it Only cost me $5 for the plug. 👍

Great idea, thanks!

Awesome work, thank you.

Awesome idea! Any suggestion regarding the angle of the wedges?

This is not a moxon vice. Joseph Moxon was about 300 years late to this idea. Its called a twin screw vice.

Links don't work.

I love keeping the sawdust on the floor for something soft to walk and stand on. It's NEVER in the way.

5 years later and this still has been one of the most useful video for me on this topic. Well done, informative and covered everything I needed.

I don’t understand how my measuring from the center of the pivot screw to the center of the kerf with a tape measure (!!! Accurate to a 32nd at best) is going to allow for calculation to produce accuracy of right angle fence to 1/1000 ???

Thanks! Will be really useful for me! Thank you👍

So where can I get this calculator

Thank you! could you provide v240 version ? we outside US and v120 is useless for us

brilliant! going to make a couple for my shop

Very effective sequence of operations. Also, the practicality of the disposability of a push stick. Thanks for sharing, man!

I’m still confused about the last question. Are you saying I can simply measure the entire distance of the rear fence, or do I have to start my measurement from the pivoting screw and then measure to the end of the fence?

Awesome calculator! Very helpful, thank you!

I hooked up a pedal switch with a splitter. If I power up the saw, the vacuum powers up too. I like this better

Well done man , keep up the good work .

What if the point doesn't sit in the middle.... how do you adjust?
