My spalted maple bowl blanks come from the firewood pile. This leads to soft spots ruining an otherwise nice bowl. Is there a product I can use to stabilize an occasional soft spot before completing the turning?— Wayne Cardoza

Jeff Roberts replies: I have no experience with it yet but Cactus Juice is the product to look into for that. You need to put it in a vacuum pot and it will get sucked into the wood and stabilise it. I have used CA glue for hardening small soft spots on spalted woods.
