Adjustable router jig for square holes or recesses

ＪＳＫさんはアイディアの宝庫で、このジグも他の海外の方々が製作されている物を見てもやはり一番です。作り方がシンプルで加工方法も素人向きで且つスライド調整及び締め付け方法が楽に出来ます。又、繰り返しの加工部分は省いてあります。特に海外の動画の時間は長いのでスキップしながら見ていますがこのＪＳＫさんのyoutubeを見ている方々は理解されて居る方々ばかりだと思います。お迎えが近く成った爺じいですがファンの一人です。どの動画を見てもジグの精度は高く評価しています。本当に素晴らしいです。

The most simple, straightforward and effective adjustable jig I've seen, many thanks!

I don't think I will ever understand why videos like this get downvoted. Personally I prefer dialogue to further explain what is going on but his videos are crystal clear with no language barrier. Another great video.

Simple, yet ingenious! It is so enjoyable watching these useful tools being created. Thank you so much!

By far the best DIY channel I ever encounter. Thank you!

A bottle of Jack as a counterweight! Man, you're a genius! :D

Clever, simple and effective! Loved it!

The best homemade rectangular hole milling tool I 've seen!

Absolutely briliant! I need this level of preciseness. Many thanks from Czech Republic.

Some people do more talking than anything. This guy is the total opposite. Absolutely fantastic. Action speaks louder than words.

ありがとうございます。シンプルで最高です。半年前位からRouterを使い始めてまだ初心者なのでこれは大きな助けになります。

Watching you work is ZEN.

You always find a way to make jigs and tools completely accurate without a lot of unnecessary frills that waste time and money. You obviously put a lot of thought and experience into every project. Please keep on sharing your projects. Thanks so much!

I love the practicality of the designs and the quite unhurried peacefulness of the videos.

Its way better than the others diy routing templates because you actually see the shape. Simply genius !

Your videos always inspire me! I went with Hardboard (HDF) and 2020 t-slot extrusions. It's given me a great deal more adaptability with being able to mount things to the sides, and to screw the hardboard onto the t-slot extrusion, from underneath. I made a 8-way version as well, with a few pieces, and can now do octagons.

I love this channel because besides making incredible tools, the protagonist is always the wood, all very clean and visible. Impressive.

Very good jig, simple and accurate! Congratulations, good job!

Brilliant !!!simple jig and like the way you have demonstrated the making of this 👌thank you

とても便利です！本当にありがとうございます！

Wooooow! Great jig and, as always, superb instruction and video production 👍👍👍👍

more simple and effective impossible, thanks you so much

Thank you so much for the amazing knowledge you share with us! God Bless!

Yet another simple but smart jig. I have some extra t-track that I may see if I can use to make one of these. Nice idea. 👍🏻

But anyway I like to express my highest compliments for your plans and projects, Well done!!

Nice work!! Thanks for sharing =)

Very useful and easy to build... thx for sharing 👍🏽

Superb, simple but so accurate and usable, well done and thanx

DE LO MEJOR Y SENCILLO QUE HE VISTO GRACIAS POR COMPARTIR TUS CONOCIMIENTOS HERES UN AUTÉNTICO MAESTRO ME DA GUSTO VER Y ADMIRAR TU MAESTRIA

РЕАЛЬНАЯ ВЕЩЬ,ПРОСТО ГЕНИАЛЬНО! ЛАЙК

Great stuff. Always interesting videos.

Thanks for sharing this design. Gotta say mine worked OK, but I really struggled to get a clean recess with it. My Makita router has a big knob sticking out at the base, which meant I had to keep rotating the router to avoid it hitting the rails, and I kept dipping the router into the recess accidentally. It's a wired router, too, so that compounds the problem of trying to rotate it 360˚ in a small rectangle. I also had some issues clamping it down...if one side was too tight the MDF boards wouldn't stay level with each other and I'd get another hiccup when moving between boards. Had a heck of a time getting the right parts in the UK, as well, and I didn't get the exact ones...nothing common fits comfortably in those t-rails; they don't seem to make nuts that fit snuggly and that would have helped (I think they do for the larger t-rails). I'm looking at other jigs for future projects that work better with my router.

ぴったりハマると きもちいですねー

Extra like for the "Jack bottle counterweight"!

Perfect! I am going to build this! Thank you! Your designs are always simple and elegant.

Muito bom seu projeto, parabéns.

Это лучшее приспособление этого рода из того,что я видел на RU-vid. Автору 5+++ ! Особенно учитывая его себестоимость по сравнению с Festool(около 300$) !

I like the counterweight on your vertical track saw.

Super man. Just what I was looking for. I'll make this over the weekend

Simple and smart, good job, keep the videos comming

very simple to use, just like to know where you got your fittings.Great to see a tradesman at work well done have already started making mine and looking at more of your projects thank you for sharing

Parabéns pelo belo trabalho. E gostei da garrafa de Whisky como contra peso. Sou de Salvador/Bahia-Brasil e fã do canal. Congratulations for the beautiful work. And I liked the bottle of whiskey as a counterweight. I am from Salvador / Bahia-Brazil and a fan of the channel.

Very creative and great idea. Nice job and thanks for sharing!

You have amazing videos

Great video and perfect build! One question: for the cut to be precise, you have to use always the same bit? Thank you for sharing!

Thank you for sharing this part, it is very helpful, for which I thank you very much.

Vey clever idea.Nice work .Congratulations

gracias por compartir sus conocimientos, esta genial esta plantilla

Simply PERFECT !!!

очень познавательно,спасибо.Удачи.

Gracias por el aporte y vídeo, excelente trabajo.....

Просто и легко. Браво автору

I love it. ✌😁 Hey you can put a tape measure on the sides. If you need a 4 by 4 cm plate, you can adjust it exactly. 📏

Absolutely amazing. Nice Work :)

This is some epic unintentional ASMR... A++

Perfection as always JSK-koubou. I’m not sure if you read these comments but. On some of your videos you have a layout parts list with dimensions onscreen, the more recent ones, can you revisit this one and add them please?

Ingenious...greetings from India.

I have such a jig for at least 30 years. And this is the first time in 10 years I see it on youtube

I like what you do ❤️

Excellent I thort of this In my mind last year but didn't act on it. Your jig is brilliant 👏👏👏👌👌👌👍

Impressive !!! Thank you for sharing.

Damn! You are awesome. 👍 thanks 🙏

Nice jig, thanks !

Perfect jig . Brazil , Beni

Absolutely brilliant

Great job thats awesome, any issues with just the double sided tape on track?

Nice work MASTER, thanks.

アイディアもさることながら、仕上げの良さと見栄えの良いのにはいつも感心させられます。ところでよく使われている電動ドリルのスタンドが欲しいのですが、氏素性を教えてください。（自作なのか購入品なのか）宜しくお願いします。

Super Arbeit Dankeschön fürs Zeigen

Genius . good job

Good afternoon, I am always watching your videos, besides the impeccable works, your working environment is great, I would like to know about adjustable jig for router, the thickness of the mdf used, the width, and if possible the length, I know that too depends on my use, it's just a parameter. I would also like to know if it works using the column router?

Merci pour la vidéo.... Difficile de faire plus simple efficace et peu onéreux...bravo

Awesome!!!!! Many thanks!

This is the best adjustable square recess jig I've ever seen, just wish I could get the plan and know where to get the slide brackets.

... Servus, sehr saubere akkurate Arbeit👍Grüße aus Deutschland

I made one from wood a couple years back on my channel buit I love yours better. Wow need to make one too now.

Handy little unit. You will always have to use the same size router bit which would be annoying if you have a lot to take out.

あなたの動画は大変参考になりました。ありがとうございます‼️

Projeto perfeito, obrigado por compartilhar.

Perfection !!! Bob
