the problem with the jig would be that your plexi workpieces should already be dimensioned perfectly. in my case i sawed em to rough dimension. when it was all assembled, then i cut the rest away.

you can plan it all perfectly if one would have 0.001 precision. doing it with cheapo tools however, makes it that much more difficult. e.g. the plexi layers only go on one way, because my threaded holes are not perfectly symmetrical. that complicates matters enourmously.

i admit though that there must be ways to make it easier, but as most of the time, good clamping is the key element, but hard to do if your workpieces don't have perfectly parallel planes. working only with copper bars therefore makes it alot easier.
