I have mentioned this before, and so it goes on. Just trying to work out if it's my own error in construction or not.
All boards I have made for my eldest son (pretty heavy, and heavy footed with it) have these circular compression dents. At first I thought it was putting boards into the water too soon, so I started giving it the full 2 weeks minimum. Then i used UV cure and still did the 2 weeks. Still got the circles on boards. So the last board i went way overboard (I always make boards strong and heavy) and this time I used quad axial glass plus 6 oz on deck. Was told this should be bomb proof. But again we have the circles. He just jump and stuff on the board so it could just be his weight and style, but if anyone thinks it coiuld be my fault in the build, please let me know!
