Overall good product, does what it's intended to do. However, the price, I would have expected better packaging to avoid damage during shipping.

Made very cheaply. You can build your own jig for much less and it will last longer. Do not get this if you want precision.

I built two boxes the very first week. Both came out great and looked like a professional had made them. This is one item, if you are looking to get into boxes, that should be indispensable for any shop. You can buy a much more costly jig, but why should you. The only way to know how it works is for you to try it. Amazon will stand behind this product if you don't like it. (get it)

Great results with this jig, straight out of the box. Works really well, good easy to understand instructions. Just make sure you do not use cheap router bits.

I found this jig to be very user-friendly on my Bosch RA1181 router table. Using a scrap pine board bandsawed/planed to 3/8” thickness, I did a couple of test runs, adjusting the spacing very slightly for the second round. The cuts were very clean even on wood this soft. I then proceeded to make a box to store the jig and sacrificial backers I made for 1/4”, 3/8” and 1/2” joints (using plywood scraps).For the next project, replicating a small cheese grating box in a larger size, I used a 1/4” spiral bit on pine for the drawer, and a 3/8” one on Swiss Pear for the outer case. The jig again worked flawlessly. Later I built another box out of pine to hold our Mercato pasta machine (got carried away carving the top for it), and it works predictably well each time. Very happy with this jig.

I bought this knowing I would need to fabricate my Kobalt router table to work with it. It can be done. My pictures have the instructions on how I did it. You will need to use the table from front to back in the opposite direction with the on/off facing away from you but it can be done.Remove all pieces of the Kobalt table first. Then remove the little bit of aluminum to allow your slide bolt to move further. Drill two holes in the Kobalt slide. You will not use the slides that came with the jig. Also, only use the hold down bolts and knobs from the Kobalt table. Hope this helps! Makes a great tool for making boxes. I love it so far! YOU WILL NEED TO PURCHASE THE SPACERS SEPARATELY. That note was conveniently tucked away at the end of the instruction booklet.

I like what this jig does but you really have to do a lot fine tuning. Once dialed in it seems to work pppretty good.

Il prodotto si presenta fatto con ottimi materiali e ben progettato.Non ho avuto modo di provarlo in quanto non compatibileInfatti vanno fatte alcune considerazioni e controlli prima di acquistarlo:Il JIG si aggancia alla t-track del banco fresa, perché si agganci è necessaria una distanza minima di 12,5 cm tra il centro della fresa e il canale, è comunque possibile allungare la fresata di aggancioL’aggancio si effettua tramite spessori in metallo da inserire nella t-track; questi una volta tirati dalle manopole dovrebbero allargarsi e garantire la stabilità del supporto. Questi spessori hanno forma rettangolare con il lato in alto di 20 mm e spessore 9,3 mm quindi vanno bene per le t-track comuni larghe esternamente 30 mm.Altro problema è che gli spessori che fanno da riferimento per creare i denti dell’incastro sono in misure imperiali: 1/2, 1/4 e 3/8.Questo in se va bene salvo che bisogna avere le frese delle stesse dimensioni e queste in genere vengono vendute con codoli imperiali e quindi poi necessitano di mandrini (pinze) del router che riescono a lavorare con queste misureInsomma niente di impossibile ma prima di acquistare fate un passaggio per verificare tutti questi dettagli, se siete attrezzati potrebbe essere un buon acquisto

I was looking to get into small box-making in the simplest way possible. I used a portable router, with an array of portable tables and jigs. For 1/4 inch joints, I started with a Dewalt 600b cordless router, a Bosch portable workbench, a Rockler Trim Router Table, a good carbide spiral up cut bit, and and this Rockler Box Joint Jig. After several days of experimentation, I came up with some pretty good, repeatable box joints. The procedure is as follows:1) Clamp the Router Trim Table to the work bench.2) Loosely clamp the Box Joint Jig the the Trim Table.3) For 1/4 inch jigs, I used a 0.25 drill bit to set the distance from the 1/4 inch brass key to the router bit. A set of feeler gauges can help zero in on the distance.4) Clamp everything tight.5) Use a digital gauge to set bit height. Set the height roughly 0.010 more than the mating material thickness. I used a Wixey WR25 3" Mini Digital Height Gauge. This gauge really makes things easy.5) Press work piece tightly against brass key, and make a test cut.6) With a 1/4 inch joint, that first pin thickness should be 0.245-0.250. If the thickness is less than 0.245, the fit will get sloppy. If it is more than 0.250, it will be too tight, and the joints will not go together. For me, about 0.248 is the sweet spot. Get some digital calipers, and learn how to use it.7) A second cut isn't necessary to dial in the fit. Loosen the clamps, and tap the Box Jig left or right as necessary to achieve the 0.245-0.250 pin width that you are looking for.8) After the first cut is dialed in, make sure subsequent cuts ae made by pressing the workpiece tightly against the brass key. The key is only about 0.243 inch in width, so this step is important.The 3/8 and 1/2 inch joints follow the same procedure. This method is working for me, particularly for small, one-off projects. You would want something more substantial for making larger quantities of joints. I want to stress, that using digital calipers, and a digital gauge for router bit depth really help make this, or any other project less frustrating.
