Fits matching chuck perfectly, added one improvement
Model: COLE JAW
Looking forward to using this. But I felt it necessary to add short pieces of 1/2" I.D. latex rubber tubing, slipping each piece over each of the 8 screw-in round hard plastic pieces that hold the wood bowl. This should greatly improve the grip. A 1-meter piece of tubing is relatively cheap and easy to buy on Amazon. Easy to cut the short lengths with regular 8" scissors. Slips on easy and stays snug. FOLLOW UP MONTHS LATER: The cole jaws have been working well. I subsequently made additional sets of screw-in posts using acetyl copolymer round rod, also buying appropriate screw lengths on Amazon with matching thread. I used 1/2" diameter rod for 1" long posts, and 3/4" diameter for 2" long posts to hold bowls where the optimal gripping zone is a bit further from the bowl edge. I used small cutoff pieces of the latex rubber tubing on the 1/2" diameter and silicone tubing for the 3/4" because it was difficult to find the latex tubing in that ID diameter. Both work extremely well in terms of protecting the wood surface and providing a good grip on the bowl. ... show more
