ok Skippy I can help you out with cutting the angles with fixtures. Now remember my fixtures might be a tad over the top because I enjoy making them more than the plugs to be honest but you can apply these principles to wooden built fixtures for sure. Don't get the idea you have to use alum. for the fixtures. Please remember these are my opinions and may not be in line with other builders of these plugs. I am not going to give my opinion on wood types, weighting or not, line tie locations, sealing and weight gain opinions, angle and slope details. These are all builder preferences that each person selects to get to the end result and way too many variables to really try and discuss in this thread. I am only going to try and give you a specific way to try and achieve a consistent end result using my way of fixturing the blanks.
There are a few operations that in my mind are very critical to having your darters repeat if you go about machining them using fixtures like I describe below.
First is after you have turned them you need to thru drill them. The thru drilling has to be very accurate in the center of the blank for at least the first inch or two, depending the size of the darter, from both ends. The middle part is not as critical as long as they meet. The fixture in the tail end will position the plug from the rear with a pin and the thru hole from the front is where the line tie will go and you need the hole to be in the center of the plug so both have to be accurate.
