So, I built this Spanish style plate joining jig 6 or so years ago. It is a very traditional way to join back or top plates. It always works great; but there is a down side. In a small shop it has a pretty large footprint and takes up a lot of space. I have a top shelf where it resides and comes down from time to time comes down to lend some help when I have multiple plate joins in process. So how do I join my plates mostly? I use a wedge joiner most of the time and for small ukulele plates I often use the stretch of masking tape coupled with a flat board. There are lots of ways to join plates. I suggest that students try different methods and see what feels most compatible with their burgeoning approach. I like using hot hide glue, which is very quick and easy in my wedge joiner and with masking tape binds great as well. For me, the Spanish plate joiner is better suited to traditional Fish hide glue which has a longer working time. Just different paths that all end up at the same destination. The real key is to make sure that the plates are dead flat against each other using very minimal pressure to join. So, if you have the space, consider a Spanish Plate Joining jig and tying one on.
