lets try this again..
Hi Bob,
The 1 3/8" holes were done with a water jet cutter. It is amazing the precision of one of these..
I called in another favor for someone to reverse-engineer the sand channels I had made, and he sent me another PDF tonight..
I apologize for jumping the gun on posting any incomplete info on these sand channels. I really like the ones that were made, and my main intention was to get some solid information out there for others to be able to replicate these. You guys have been more than generous, and a wealth of knowledge for me when I needed it, and I want to give back to the hobby...
The PDF is only one drawing, but I will send it to anyone interested..
Thanks, David
