Key Features
Dead-Center Mortises Precision-machined spacers set the fence plate at fixed offsets, so you can center Domino mortises in common sheet goods and solid stock without fiddling with the factory reference plate. Long-Range Layout The outrigger system extends up to 54 inches, giving the Festool Domino a stable way to repeat mortise locations across wide panels, long parts, and production runs. Built Like a Fixture With 1/4 inch aircraft-grade aluminum plates and 3/4 inch stainless steel spacers, this Woodpeckers joiner accessory is made to stay rigid and repeatable instead of drifting during repetitive cuts.
Overview
Woodpeckers Domino DF 500 Offset Base System, Imperial is an aftermarket joiner accessory built for the Festool Domino platform. This is a joiner accessory designed for accurately centering and repeating mortise locations in sheet goods, panels, and solid wood parts. Model Number DF500-OBSI-18. If you use a Domino for cabinet parts, furniture components, or long production runs, this system gives you a larger, more stable reference surface and a faster way to hit the same mortise location over and over.
The big advantage here is repeatability. Instead of adjusting the Domino reference plate up and down and hoping you land on the same mark every time, the Woodpeckers system uses precision-milled spacers to positively set the fence plate in fixed positions. That matters when you are working with common 1/2 inch and 3/4 inch material, 23/32 inch plywood, or common 12 millimeter and 18 millimeter plywood. Pick the right spacer set, bolt it in place, and your mortise location stays consistent from the first part to the last.
This system is also built more like a fixture than a simple add-on. The attachment plate fastens to the Domino base with two screws, and the fence plate bolts to the attachment plate through stout 3/4 inch diameter stainless steel spacers. Woodpeckers also uses precision-machined 1/4 inch aircraft-grade aluminum for the attachment and fence plates. In plain terms, that gives you a rigid platform that resists fence drift during repeated cuts. If you have ever had a setup shift just enough to ruin a row of parts, you already know why that matters.
The larger footprint is another real upgrade. Compared to the stock Domino base and fence, this system gives you a platform that is over 2 inches wider and a fence that is nearly 3/4 inch longer. That extra bearing surface helps on narrow edges and awkward panel work, and the 2 inch knob gives you a more secure grip when you are pushing through a cut. It is not just about comfort. Better control usually means cleaner, more confident mortising.
For layout work, the Imperial version uses laser-engraved inch scales in 1/16 inch increments. The scale is aligned to the Domino cursor and extends 2 inches left and right on the base. The included outrigger system pushes that concept much further. Its five machined sections can be connected to extend the reference range out to 54 inches, which makes a big difference when you need evenly spaced mortises across long cabinet sides, shelves, face frames, or wide panels. The flip stops lock in place with zero lateral play, so once you set a pattern, you can keep feeding parts without chasing measurements.
Compatibility is straightforward. This system fits the Festool Domino DF 500 out of the box. It also works with the Domino XL 700 when used with the XL700 5 millimeter adapters noted by Woodpeckers. That makes it useful for shops running more than one Domino size, especially if you want the same offset-base workflow across different joiners.
Who is this for? Cabinetmakers, furniture builders, trim shops, and serious woodworking users who rely on the Domino for repeatable joinery. If you only cut a few loose-tenon mortises a year, this is probably more accessory than you need. But if your work depends on accurate spacing, centered mortises, and faster setup on multiple identical parts, the Woodpeckers Domino DF 500 Offset Base System, Imperial is the kind of upgrade that pays for itself in fewer setup errors and smoother production.
More Stable Mortising on Panels and Edges
The larger base and fixed spacer system make the Domino easier to control when you are working on panel edges or stock where a small error shows up fast. This setup is built to keep the reference plate where you set it.
- 3/4 inch diameter stainless steel spacers create a fixed offset from the cutter
- 1/4 inch aircraft-grade aluminum attachment and fence plates add rigidity
Lay Out Repetitive Joinery Without Re-Measuring
The outrigger bars and flip stops turn the Domino into a much more repeatable layout tool for casework and furniture parts. Once your stops are set, you can run matching pieces with less measuring and fewer chances to drift off pattern.
- Five outrigger sections extend the system up to 54 inches
- Flip stops lock in place with zero lateral play for dependable repeated positions
Works Across More Than One Domino Setup
If your shop uses the DF 500 now but may add a larger Domino later, this system has some useful flexibility. It is designed for the DF 500 out of the box and can also work with the XL 700 when used with the listed adapter setup.
- Fits Festool Domino DF 500 without modification
- Also works with Domino XL 700 when using XL700 5 millimeter adapters

Pro Tip
If you are batching cabinet parts, keep each spacer set labeled with the stock thickness you use most. Once you lock in the right spacer and flip-stop position, you can remake a part later and put the mortise back in the exact same spot without resetting from scratch.
