## Overview

Featuring a durable MDF platform with a low-friction melamine coating and solid brass indexing keys, it supports 1/4", 3/8", and 1/2" joint cuts. Included hardware ensures easy setup and tear-out control, while compatibility with up-cut HSS router bits (sold separately) guarantees professional-quality results.

## Description

Durable MDF platform with low-friction melamine coating for easy sliding. Solid brass indexing keys ensure uniform spacing and tight finger joints. Matched with HSS router bits for precisely fitting joints. Sacrificial MDF fence face helps control tear-out. Ideal for creating coping joints for small and medium boxes and frames. Cuts 6 mm (1/4"), 10 mm (3/8"), and 13 mm (1/2") box joints on a router table. Includes MDF platform, 2 x soft-grip knobs with mitre track hardware, 1 x sled, 1 x sacrificial fence face and 6 mm (1/4), 10 mm (3/8) and 13 mm (1/2) brass indexing keys. Up-cut HSS router bits sold separately.

Review: Il prodotto si presenta fatto con ottimi materiali e ben progettato. Non ho avuto modo di provarlo in quanto non compatibile Infatti 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 aggancio L’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 misure Insomma niente di impossibile ma prima di acquistare fate un passaggio per verificare tutti questi dettagli, se siete attrezzati potrebbe essere un buon acquisto

## Questions & Answers

**Q: can I make .125" joints with this kit?**
A: It does not come with a .125 spacer but you could make one.  It could be made of metal or hardwood perhaps and you would have to find a .125 upward spiral milling bit.  Do not use a rabbiting bit.

**Q: Is there any horizontal adjustment to make the tongues wider or narrower**
A: The jig comes with 3 keys: 1/4, 3/8, and 1/2 inch. You can probably fabricate other sizes in between, but the jig is not big enough to accommodate much lager keys. They have another jig for that.

**Q: This picture doesn't match the one on rockler's site -- is this an older version?  which one will i receive if i order it?**
A: They only make two models, this one and the XL version which also does 3/4 cuts. There is no 'older' model.

**Q: I have a milling table and the distance from the strawberry to the rail where the rockler box joint is squeezed is 13.5 cm. would it be worth my table**
A: Router Table Compatibility: Near edge of router table's miter track must be between 4-1/2'' and 6-1/4'' from the center of the router bit
