How to make an adjustable dado jig for trimmers 

Thank you for your comment. Your comments were very encouraging to me.

Спасибо за ваш комментарий. Я рад, что это было полезно.

Thank you for your support. This will encourage me to create future videos.

The bit I replaced is a top bearing pattern bit with the bearing attached to the base of the bit. Originally, this jig can only be used with specific bits. In that case, press the side of the base of the trim router against the guide plate on the top of the jig while cutting. In the case of the replaced top bearing pattern bit, cutting is performed while pressing the bit bearing against the guide plate (thin plywood) at the bottom of the jig, without pressing the side of the base of the trim router against the guide plate at the top of the jig. It is possible to perform cutting without changing the jig. *The bit diameter of the top bearing pattern bit must be larger than the diameter of the specific bit. Sorry for the lack of detailed images of that part in the video.

Sorry, we are currently considering releasing the drawings and dimensions of the jigs, etc.

Спасибо за ваш комментарий. В видео используются фрезы (биты) стандартные прямые, спиральные (используются для обработки сквозных канавок) и сверла с подшипниками.

Thank you for subscribing! The name of the router bit I use is Spiral Bit. www.btmt.jp/SHOP/168781/list.html

Thank you for the quick reply :) Unfortunately it's all in Japanese and when I look at Amazon there is a spiral up cut and a down cut. Not sure I presume it's the down cut? Thank you

Down-cut spiral bits are used in the video.

The direction of the cut will help expel the cut sawdust. So for a shallow cut use an up-cut spiral bit to push the dust up. A down-cut spiral bit will push the dust down which is useful if your router bit is going all the way through the wood. You can buy combination spiral cuts, where the bottom of the bit pushes the dust up and then the cut transitions to a downward cut at the top of the bit. This is useful if you are making multiple passes and slowly lowering the router cut with each successive pass. Hopefully I explained that well enough. 😊

Thank you for your comment. We are currently considering disclosing the details of the dimensions.

The parts used in the video are M6 T-bolt (for 19mm T-slot track), handle with M6 screw hole, and T-slot track 9.5mm x 19mm. It's Amazon Japan, but I'll post the product link. M6 T-bolt　amzn.to/4armsde handle with M6 screw hole　amzn.to/43IMbvh T-slot track 9.5mm x 19mm　amzn.to/4cA1wCu

This model will be the RT50D sold in Japan.

Thank you for your comment. I would like to consider it.

コメントありがとうございます。 検討してみたいと思います。

治具加工時に使用したビットを使用するのが基本ですが、そのビットより大きい径のトップベアリングパターンビットを使用すると、治具を同様の使い方で同じ溝加工が出来ます。

@@tiny-cabin-woodworks 大きい径の場合は、治具をベースプレートのガイドとしてではなく、ならい彫りのテンプレートとして使うような意味合いになるということですか？

今回の動画でも終わりの方でそのような使い方を紹介しています。

@@tiny-cabin-woodworks ベアリング径が太くなればその差分だけ、際に彫り残しが出るので、初めにガイドをその分だけ幅広に取ってやれば、ぴったりになるということですね。ありがとうございました。
