I built a couple dozen Blum "Tandem Plus" kitchen drawers many years ago (3/4" prefinished maple), with the grey metal sides and they were relatively easy to build and install.
Now it's time to build a bunch of built-in vanity drawers and I planned on using Tandem Plus, but the parts seem to be much harder to find, plus I see a couple things that I like about the new Blum line, Legrabox.
I don't build cabinets very often and I'm curious if it's much of a leap in difficulty to switch to Blum Legrabox for this batch of drawers.
Blum recommends a jig for drilling the drawer pieces, but I don't think I'll need that since I'm using plywood. I didn't use any jig to build the Tandembox drawers. It seems like slide mounting would be similar. Building the drawers looks straight-forward.
I haven't found any videos about mounting the runners for a DIY. I'm trying to avoid surprises.
