Woodworking filter: I need to seal a leak in a wooden vessel but whatever I use needs to be both food safe and high temperature resistant.
Long story short I am recreating an old Finnish brewing method of making something called sahti
. When making sahti, you filter out your grains from the liquid using something called a kuurna, which is a long wooden trough typically made from a hollowed out log. The grains and liquids when poured into this kurrna will be just below boiling temp, around 80deg C (176deg F).
Since this was my first time hollowing out a log, I didn't know what I could and couldn't do. I got a bit over-zealous with the ax and cracked the log on one end. Thinking I could fix this easily, I continued.
Upon testing the kuurna with water yesterday, this thing poured water out like crazy. I need to find a solution to patch it if I am going to salvage my 1/2 of a weeks worth of work.
Here is a link to what I am working on
. And on the last photo, you can see the crack.
Any thoughts? I would love not to scrap this and start over. Thanks!
Oh and I have tried using a high temp epoxy, but it doesn't fill the gsp. I need something that can fill.
