Showcase cover image for Japanese Sumitsubo Ink Pot

General Information

this project was my entry into a Marking Tool Swap on another forum.
having never fabricated such a project before, I made a prototype in High Density Urethane (HDU)
which carves like balsa wood with no grain. it took about 2 hours to go from paper pattern
to final working HDU prototype.
when I was ready to start the real thing, I purchased a chunk of wood off of E-Bay
(species unknown) and delicately finessed it for two months into a working, fully functional
model using hand held grinders, sanders, various carving knives, chisels and gouges.
the string wheel was turned on the lathe.
Black charcoal powder is from my local art store.
while viewing many videos on YouTube, I saw that the black ink is a problem when working
in the shop. it is messy, and if not used often, the ink dries out and coagulates in the pot.
so ~ I decided to use artist’s black charcoal powder instead. now, it performs like the modern
chalk string line with no shelf life for the powder.
the inside of the pot was coated with thickened black epoxy to make it leak proof in case the recipient ever wants to use the traditional black liquid ink.
the outside was coated with clear satin urethane.
all in all, it was a fun project.

Beautiful piece John. Love how you capture the build with the photos.

Question, are the small holes on the string wheel decorative, or serve a function? Not familiar with ink pots.

thanks Nick - I don't see a need for the holes in the wheel, so they must be purely decorative.
YouTube has many videos on this tool that I got a lot of good pointers from.

oh - if you look at the front, there is a small metal tag thing to hold the string.
that is a 1970 "One Ore" coin that I got when I was in Norway back in my Navy days.
they stopped production of the One Ore coin in the mid-80s. so it adds a little more
personal touch to the project.

Never would of known the origins of the coin. Definetly a nice addition.

I'm curious to see what you get in the gift exchange. Are most of the items this detailed and thoughtful? Sounds like another wonderful forum.

Nick - the theme of that "Tool Swap" was for "Layout & Marking Tools" 2018.
the skill levels of the members vary like on any forum from beginning ameatuer to professional.
so the items in the exchange will vary according to the skill level and imagination of the participants.
and there are no rules other than stay within the theme of the topic: you can be a member for two days or ten years - it doesn't matter.
and yes, I think that most woodworking forums on the internet have something to offer for everyone.
these are the items that I made for my entry.

last year's swap (2020) was themed "BackYard BBQ" ~ so any wood related BBQ tools and accessories could be swapped. the names are drawn at random, just like any gift exchange.
this year, it is a "Surprise Swap" with no limits on what could be built as long as it was made from wood or contained wood in the application. and there is no limit as to where you live in the world, either. Australia, Canada, USA, Japan, Mexico, United Kingdom, doesn't matter. it's all in good fun.
thanks for the interest.
