100V to 18V Chainsaw Conversion | RYOBI CS 3601 Electric Chainsaw

Cord to Cordless Chainsaw Conversion Video
I found this chainsaw from a Japanese recycling shop. It does not work anymore because the armature is broken. I decided to convert it to an 18V cordless chainsaw by rewinding the armature and replacing the field with a permanent magnet. Let's see it in detail in this video.
More information could find in the community https://www.youtube.com/channel/UCWKqh_3cb6cDiz2ICWc-5Sw/community.
After the test, I felt it needed more speed, while the torque and power were good enough to cut the tree. It would be better with a 24V battery.
To be honest, this chainsaw is much better than the 18V Black & Decker that I just restored https://youtu.be/IgDk1cf0lmw
It is easier than my previous 36V chainsaw conversion https://youtu.be/wDL22c-zi8k
I hope you find this video useful and enjoy it!
Furthermore, I am happy to receive feedback, suggestions to improve myself.
!!! I'm sorry for the mistake if I did in this video !!!
Thank you very much for choosing to watch my video!
Have a nice day
