I just found a new type of log holder. I will post it here for you to see also. I think I'm going to order it. I will submit a review after I have tried it out. I see that they have a 5-star rating.
Secure your logs in place while cutting Tenons, tapering the log, peeling the bark and more with our all new log lock. This heavy-duty log holder will eliminate slipping, turning, and other issues. This quality product has great features at an affordable price.
