Hi Meen,
It is great to see your enthusiasm for learning bushcraft. Nice quality video too!
I just edited your last post to show your actual video. We ask folk to post embedded videos, rather than links that take people away from this site. I am sure you want people to subscribe, but posting a link that auto-subscribes people that click it (albeit with a yes/no option box) isn't the way to do it here. Just keep posting and it will happen. To that end, it might be good to start a thread somewhere else specifically for this chair. There are certain people that welcome new members in the Intro area, but there are others (more?) that look and search the dedicated sub forums. If you have a thread about making a chair it should be Google searchable, whereas in here it could get overlooked.
A separate thread might also get more people commenting on the video.
For instance, for using a bow-saw for cutting small wood, have you seen the technique where you put the saw on the ground, trap it with the blade vertical, away from you and move the wood against it? This is the best I can find...I tend to use my toes to hold it down. Small feet definitely help with smaller saws!
