Accurate layout marks get you only partway to a clean cut. The next problem is holding the stock at a height where the tool can do its work, and that is where support pucks come in. Before you set up the bench, make sure your essential layout and marking tools are in order, because a precisely marked board is only useful if you can hold it securely while you cut, route and sand. Support pucks are small blocks that lift a workpiece above the work surface to create clearance underneath. They come in rubber, plastic, cork and hardwood, and a set of four can carry a few hundred pounds of stock. The methods in this article apply to any shop, from a home workbench to a production cabinet line.
Why Workpiece Support Matters
Support blocks have become standard shop equipment as the woodworking renaissance has brought more routing, sanding and finishing work into home shops. The reason is simple: many operations need clearance below the workpiece, and a flat bench gives you none. Without a lift, an edge router bit bottoms out on the bench, a sander grinds into the surface and wet finish welds the panel to whatever it touches.
Tasks that need under-work clearance
- Edge routing: the cutter must pass below the face of the board, and a puck lifts the stock high enough for the bit to travel the full edge.
- Sanding edges and profiles: elevated work lets you reach the full edge without the bench blocking the sander.
- Finishing and painting: the workpiece rests on small points instead of a solid surface, so wet finish does not stick and pull.
- Clamping from below: a 1.5 inch lift leaves room for clamps under the workpiece.
- Dry fitting joinery: you can shift boards and check joints without lifting the assembly off the bench.
The right lift height depends on the tool. A trim router with a short bit needs less clearance than a plunge router with a long bit, so measure the bit travel before you set the pucks. For sanding, any stable height works. For finishing, you want the smallest contact area you can get, which is why point-style supports exist.
Materials and Designs of Support Blocks
Support blocks fall into two broad families: manufactured pucks molded from rubber or plastic, and shop-made blocks cut from hardwood. Both do the same job, but the material changes grip, durability and how the block treats the finish.
Manufactured pucks in rubber, plastic and cork
Molded pucks usually carry a grippy surface on both faces so the workpiece stays put and the puck does not slide on the bench. Some add a retractable point in the center that extends with a twist of the block and locks in place. The point gives a small contact area, which keeps wet finish from sticking to the support.
Shop-made hardwood blocks
A traditional option is a set of blocks milled from dense hardwood offcuts. Ash is a common choice because it is hard, stable and inexpensive. If you are new to the species, read up on what to know about ash wood before milling your first set, since grain direction and moisture content affect how the blocks behave.
Which material to pick
- Rubber and plastic: best grip, quiet, will not dent most stock, slightly flexible.
- Cork: gentle on finishes, absorbs vibration, wears faster.
- Hardwood: rigid and stable, cheap to make, can dent soft stock if the bearing edges are sharp.
Painter’s Pyramids, Bench Cookies and Multi-Purpose Pucks
The market now offers three common solutions: painter’s pyramids, bench cookies and multi-purpose pucks. They overlap, but each has a different strength, and the prices differ by an order of magnitude. Painter’s pyramids sell for a few dollars a dozen, bench cookies cost a little more, and a four-pack of multi-purpose pucks runs about $20, so the right choice depends on how often you finish versus how often you route.
| Option | Typical lift | Load capacity | Best for |
|---|---|---|---|
| Painter’s pyramids | 1 to 1.5 inches | Light, per piece | Finishing and painting at low cost |
| Bench cookies | About 0.5 to 1 inch | Moderate | Work support with add-on accessories |
| Multi-purpose pucks | 1.5 inches | Up to 200 lbs per set of four | Routing, sanding and finishing in one tool |
| Shop-made hardwood blocks | Any height you cut | High | Custom heights at zero cost |
Painter’s pyramids
Painter’s pyramids are small plastic points that hold a panel on its edges while finish dries. They cost very little and work well for flat panels, but they tip easily and offer almost no grip, so they suit finishing more than routing.
Bench cookies
Bench cookies are cork or rubber discs that grip the workpiece from below. They are stable and can be accessorized with threaded inserts for holding fixtures, which makes them a favorite for routing work where the workpiece needs to stay put.
Multi-purpose pucks
The newest option combines both jobs in one block: a grippy puck for work support and a retractable point for finishing. Twist the top to raise the point, and the same puck that held the board for routing now holds it for painting. The conversion takes seconds and needs no extra parts.
Before you set freshly elevated stock on pucks, check the board for embedded metal. Salvaged and reclaimed lumber often hides nails and screws that can ruin a router bit or score a finish. A quick pass with metal detectors in woodworking catches hidden fasteners before they cause damage, which matters most when you work with recycled material.
How to Use Support Pucks Safely and Effectively
Support pucks are simple tools, but the setup routine decides how well they work. Work through the same sequence every time so nothing slips.
- Clean the bench and the pucks. Sawdust under a puck makes the whole setup unstable.
- Position four pucks near the corners of the workpiece, inside the edges you plan to cut.
- Set the board and press down so the grippy surface seats against the stock.
- For finishing, twist the points up and lock them, then set the panel on the points.
- Rotate the workpiece between passes so you work on the same side every time.
- Check stability before starting the machine, and re-check after each reposition.
Pucks keep the work stable, but they do not replace safe machine habits. Review table saw safety regulations and apply the same discipline at the router table and the bench, because elevated stock changes the geometry of every cut and a spinning cutter does not care how confident you feel.
Stability checklist
- The bench is flat and the pucks are clean.
- The workpiece overhangs the pucks by no more than a few inches on the cutting side.
- All four pucks touch the stock evenly, with no rocking.
- Clamps, if used, bear on the pucks, not between them.
Lift Heights, Load Ratings and Grip
The two numbers that matter on any support puck are lift height and load rating. A common lift height is 1.5 inches, which clears the bit of most trim routers and leaves room for clamps underneath. Load ratings vary widely; a set of four pucks rated at 200 pounds total carries about 50 pounds per puck, which covers most solid-wood panels but not heavy assemblies.
| Feature | Typical value | Why it matters |
|---|---|---|
| Lift height | 1.5 inches | Clears router bits and clamp heads |
| Load per set of four | Up to 200 lbs | Sets the ceiling for panel weight |
| Contact surface | Grippy on both faces | Stops the puck and the work from sliding |
| Base shape | Non-rolling hexagon | Keeps pucks where you set them |
| Finishing points | Retractable, twist-lock | Small contact area prevents finish sticking |
Reading load ratings
Load ratings assume the weight is spread evenly across the set and the bench is solid. A puck rated for 50 pounds will fail early if you bounce a 40-pound panel on it during routing, so add a margin of 25 percent or more for dynamic loads.
Fixed height or adjustable
Most pucks are fixed-height, and that is fine for most shops. Adjustable designs add complexity and cost, but they pay off when you regularly work with stock of very different thicknesses and want the same support height every time.
Grip and marring
Grip is a tradeoff. Soft grippy surfaces hold better but can imprint soft woods under clamp pressure. Hard points mar less but slide more. Match the puck to the job: grippy pucks for routing and sanding, point supports for finishing.
Finishing, Sanding and Larger Projects
Support pucks earn their keep in the finishing and sanding phases, where the workpiece is most vulnerable. When you sand elevated work, pair the pucks with a sensible sanding disk selection so the grit sequence and pressure stay consistent from edge to edge.
A finishing workflow that works
- Sand to the final grit while the work is on grippy pucks.
- Wipe the dust off with a tack cloth.
- Twist the finishing points up and lock them.
- Set the panel on the points and apply the first coat.
- Rotate the panel between coats so the points do not rest on wet finish.
Keep the finishing points clean between coats. A dried drip of varnish on a point becomes a bump that marks the next panel, so wipe the points with solvent after each finishing session and store the pucks where sawdust does not settle on the grippy faces.
The same blocks carry bigger jobs. When you build curved assemblies, the ability to set panels at a working height makes glue-up and clamping far easier, so keep a set of pucks next to the bench for bent lamination projects and other large glue-ups. A small investment in support hardware pays back in cleaner cuts, smoother finishes and fewer ruined panels.
