Review: Some problems but brilliant bit of kit - Had a problem where the bars of 5 star restraining knobs did not fit into track. However, by using my feather board bolts from same track it worked perfectly (thank you other desertcart user that suggested it). Once everything in place. Off you go. Brilliant piece of kit. Very happy and easy to use. Review: Easy to use / set up - Great results with this jig, straight out of the box. Works really well, good easy to understand instructions.

I attached it to a larger base with guide rails which fitted my router table, which worked OK. I did the same with the Rockler spline jig. **Q: Is there any disadvantages to this being an imperial model? I suppose I couldn't use metric bits could I?** A: You could use metric bits but I'm guessing the holes cut out by the metric bits will be a fraction out from the brass inserts. Only way around this would be to accurately measure the brass inserts and compare them to the imperial. If needs be, either buy new bits to fit OR shave down/add shims (good use for an old feeler gauge) the brass inserts so they match the metric bits you have ## Customer Reviews ### ⭐⭐⭐⭐⭐ Some problems but brilliant bit of kit *by A***S on 24 September 2022* Had a problem where the bars of 5 star restraining knobs did not fit into track.

Just make sure you do not use cheap router bits. ### ⭐⭐⭐⭐ Pricey - but I needed a treat *by A***S on 31 January 2022* It's everything I expected it to be. Not sure how long the t-slot track will remain sturdy being mounted into MDF. For the price I would have expected it to have an aluminium base - but hey - I knew what I was buying. I see a question regarding will it fit on Lumberjack RS1500 - yes it will - though you need to borrow some parts off the front feather board that slot into the narrower t-track and all is then good and solid. Bit of a learning curve - of which i'm only part way through but initial cuts look promising. Deffo get an upcut spiral end bit for this - straight cut just tears everything out. So as it was a treat - I'm reasonably happy - but I could have made it myself for far less ## Frequently Bought Together - Router Table Box Joint Jig - Finger Joint Indexing Keys w/Three Finger Widths ¼”, ⅜” & ½” - Stable MDF Router Fence w/Low-Friction Melamine Coating - Knobs to Lock Platform w/ ¾” Miter Slot - SPEED TIGER Carbide Spiral Router Bits Up Cut - ISEU1/4” Diameter, 1” Cutting Length, 2-1/2"OVL (1 Piece, 1/4") - for Wood, Oak, MDF, Aluminum – Mill Bits Sets for DIYers & Professionals - SpeTool Spiral Upcut Router Bit 1/2 Inch Shank with Extra Long Life Coating, Carbide CNC Router Bits End Mill for Wood Mortises Carving Engraving --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/79582411-422866-router-table-box-finger-joint-jig-1-4-3](https://www.desertcart.hr/products/79582411-422866-router-table-box-finger-joint-jig-1-4-3) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
