Tagger.. how about "Roll Orientation".. ? Ever try it to compare to Hydro?
Two old guys I have talked to, (one on here
) have told me of this method. One of them built commercial for years...
two parralell thin gage angle iron on level bench top.. roll the plug slowly along it, let it settle... make a line.. do it again to check...and, it doesn't raise the grain...
When I get organized, and building again, I'll give it a try.. have not built a plug in months
