I tried to turn a segmented Tamboti Bowl, but unfortunately my gleu joint failed and the whole thing come of the lath. I really didn’t see this coming. I was very careful with the speed and made sure my turning tools was sharp.

Bummer…it was looking good too.
I made segmented cane with one piece of Cocobolo in the middle of it all. It broke free during the turning and it was like it never had glue on it. Found out it’s always best to clean glue joints of oily woods with acetone first.

doubt it was the speed or tools but the glue. PVA glues, white and yellow glue, are around 50% water. The old phrase “oil and water don’t mix” probably to blame. These glues count on the water penetrating to bond and they can’t do that on an oily surface. Wipe the surface good with mineral spirits and see if your rag gets an oily tint then thats your problem. you could use 2 part epoxy or maybe a polyurethane glue like gorilla glue. Or glue immediately after wiping the joint down joint with acetone or mineral spirits if using a pva glue….before any oil seeps back out.

Thank you for the advice, I’m still a novice when it come to turning. I have another peace of Tamboti laying around and will defiantly try to make another bowl and clean it before glue up.
