What a beautiful piece of spalted maple crotch I've got on the lathe here until we get right there. Now, one of the things that makes spalting happen is that material sits on the ground, gets wet, spalting is actually a fungus that starts growing into the wood. So this can be a by-product of that, which is wood gets wet and it starts to rot, or get punky like this. Don't despair, we don't wanna throw the baby out with the bathwater here and get rid of this beautiful bowl blank only because we have that bad spot. So the answer to this is CA glue, cyanoacrylate. What we can do with this is support this spot, fill it in, build it up a little bit, and with that we're gonna stabilize the turning and be able to finish the bowl. So, I'm just gonna let the glue flow. I'm using a medium viscosity, thin enough that it'll flow down into any voids, thick enough that it's not running like water off for the turning. Now this is gonna take a couple applications so I'm gonna put this layer on, give that the opportunity to dry, come back, do another layer, another layer, until I've got these voids filled, that area stabilized, that'll prevent a bowl from blowing up when I start working on it again. I've got our bowl completely turned, flipped around, finished the bottom off here, just doing a little polish on the finish. Now let's rotate around to where the bad spot was, that's it right there. Now, one of the things that's cool is that the glue really just adds a little dark to the bowl well there's dark in there already so it doesn't cost us a thing as far as any kind of a compromise on the bowl. Now, what I wanna do is get it off of this mounting system so you can have a look at the entire finished product here. Here's our finished bowl a really beautiful piece of spalted maple. It came from a crotch piece so we've got a beautiful example of the crotch of the tree right there and our repair on the outside of the bowl, facilitated by CA glue, and really without that CA glue this bowl would've ended up in the fireplace pile instead of the bowl-turning pile. So, thanks to some help from CA, we salvaged a bowl and got a beautiful spalted turning out of this.
What if the whole piece is punky? Im getting loads of tear out on the end grain sides of my bowl Is there a way to fix this without vacuum equipment?
I believe it is a Longworth/Bowl Finishing chuck... I want one as well. Looks way awesome
George, I'm interested in that mounting system. I've not seen anything like that. Where can I found out more about it?
