Topic tags/keywords: sumitsubo parts question

Last weekend on a workout I dropped and lost the wheel crank of my 20 year old wood sumitsubo and a replacement is not so easy to find. Any help with sources where they might be available, (probably I would need both the crank and wheel for compatibility), for order would be appreciated.

since I have never heard that name before, I did the ole google thing and found
several nice examples – as well as a video on how to make one.
is your sumitsubo mass produced? or was it hand made one at a time.
using the YouTube videos, this looks like a fun project to make just for fun.
if you still have the wheel and it is undamaged, I would think a new handle
would not be that hard to fabricate yourself.
could you please post a photo of the one you have?

I am watching this thread with earnest.

Yes, I have had a nice blank of zelkova wood sitting on a workbench for years now waiting on me to use it for making a sumitsubo, even one suitable for left-handed users like me, being a lefty you know, just because it would be a nice project. In that case even fabricating the metal parts would be fun. It is one of the projects that keeps getting put off, and so it goes. In the meantime I sure could appreciate the convenience of the consumer option.
A simple model, it is mass produced and at the same time, has involved some hand work as I understand it.

I wrote up a little story about it and its use just here

wow thanks for sharing, Ernest !!
now, not only do you need to repair your sumitsubo,
you get to make another one tailored to your needs.

my two bits would be to make a special wooden box for it.
I come from a very long line of craftsmen that made their own tools
back in the 18 and 1900s. I have never seen anything like this sumitsubo until now.
thanks !!

A funny thing is there is no difficulty getting ahold of a replacement anchor pin, attached at the end of the line, and yet the one easily detachable, and thus vulnerable to getting misplaced, part, the crank, is ever so elusive even to the point of unattainable.
I know, I know, I should quit moaning about it and, as you say, make a new one.

Have your say...
