So you have an LS Positioner? If so you are not constrained by the templates. For a blanket chest you're probably using 3/4" stock and, for through dovetails, will be using the 5/8" or 3/4" dovetail bits. The Reference Guide advises a spacing of 1-1/16" and 1-5/16" for these bits and as long as you maintain the spacing in increments of these measurements you can space the dovetails at whatever you like. There's always the option of making the end pins wider to take up any minor variation due to the width of your stock. To reduce the chance of errors draw up the joint on a sheet of paper and mark the position of your A and B cuts on it.
The other option is to machine cut your dovetails at whatever spacing you like and then hand cut the pins. I bet you could do this in a fraction of the time it would take you to learn to use a Leigh D4R.
