The basic size is 2 x8 shhets of 1/2" plywood. The center hole is a 36" radius, the top corners 18" radius. I used a circle-cutting jig and plunge cut router to cut them. I made the brackets out of 1/8" aluminum, cutting a 1/8" notch at 1/2" intervals. This worked out to be about 1degree of change in swing plane for each notch. The bracket os attached to the board with a 90" aluminum angle and locking nut/ bolt. Hope that helps, Tom
That's 2, 4x8 sheets of plywood. Note that the standards for the legs are offset so that it will fold flat. The hinges are mounted to 3/4" hardwood, which is screwed and countersunk through the face of the board..
Hello, the radius is is 36", circumference 72". If I had it to do over I'd radius it at 39". the 1/2", 9-ply birch ply-wood is plenty rigid enough for the perimeter edges and it would give just a little more clearance on the swing.
Hey Tom. If you could reply to let me know if you still have this email active I’d like to get some help on building this and I’m stuck at how you cut the notches into the metal
If your serious about buying one I can do a lot better than that price wise. Shipping may an issue, I'm in the northwest. Email me at thomasrewing@msn.com
Great design work! Can you inform of the specifications of this? Also, where can I get the angle bracket to adjust the slope of the board? and how is that attached to the board? Please include close up video of how it is all attached. Thank you.
I do not believe in anonymous comments and wanted to give a honest response to why I expressed a dislike of this video. I'd like commend you on a good try at implementing this but there is a mistake. This device assumes one plane for the back and forward swings, which is fundamentally false. This is evident by the fact that both golfers videoed leave the board during their forward swings. This board doesn't allow for the route the club makes on to the finish .i.e. depth.
