Build a Replaceable-Brush Boot Scraper. Check the dimensions and build steps before cutting.
02 / Plan your build
Before you start
Replaceable brushes do the cleaning, so no exposed metal blade is needed. The base keeps the brush spacing repeatable, and a tray catches loose dirt. Use it seated or with a separate secure hand support; the base is not a step or balance platform.
Where it goes
A dry level entrance or covered work area with reliable nonslip support and a separate handhold; outside emergency paths.
Footprint: 24 × 12 in frame size; allow room around it to work and for anything that projects.
What to expect
Measure accurately, make supported square cuts and drill clamped joints. Plan 2–3 hours after choosing the actual brush blocks.
A planning estimate for the hands-on work, once the materials are bought and the tools are set up. It has not been timed on a finished build.
Check the spot
- A dry level entrance or covered work area with reliable nonslip support and a separate handhold; outside emergency paths.
- Measure the usable stock before marking. Keep the assembly area flat and large enough to clamp the work without reaching across a moving cutter.
Stop and check first if…
- Stop if a part splits, a fixing strips, or the assembled object rocks. Unload it before opening a joint.
- Do not substitute an unknown material section or make the object taller or wider without checking every affected part and joint.
Work safely
- Use the scraper while seated or holding a separate secure handhold. Never stand on its wings to stop sliding; stop and correct the pad/floor fit instead.
- Keep the tray path and floor free of mud and water. Ventilate while finishing, follow the finish label for cleanup and rag disposal, and let it cure fully before fitting grip pads.
Budget
We have not put a price on this one yet. Lumber and hardware prices change by store and season, so price the list under What you need at your local supplier before you buy.
03 / Gather and cut
What you need
B — Wide base
1 piece
Exterior-rated plywood, actual 0.75 in, smooth and sealed according to a suitable finish label. Buy one exterior-rated plywood panel at least 24 × 24 × 0.75 inches and cut one 24 × 12-inch base with a sound edge.
Measure your boards before cutting. Build to the finished sizes written here, not the nominal lumber label.
R — Brush mounting block
2 pieces
Sound untreated surfaced 2 × 2, actual 1.5 square. One 2 × 2 × 4-ft board.
Measure your boards before cutting. Build to the finished sizes written here, not the nominal lumber label.
K — Replaceable brush block
2 pieces
Stiff nonmetal boot-cleaning brushes with solid mounting blocks and manufacturer-approved attachment points. Two matching brushes; reference blocks 10 × 1.5 × 1.5 in.
Measure brush and bristle projection before fixing the gap.
T — Catch tray
1 piece
Rigid washable catch tub at most 9.5 × 8 × 0.5 in INCLUDING its rim; slides forward along the base. One washable tray.
Slide out through the open front under the brushes; do not lift it through the bristles.
Base screws
8 items
#8 × 1.75-in stainless wood screws Purchase at least 8; keep spare hardware separate from the installed count.
Use one consistent product and follow its pilot and driving instructions.
Brush fixings
4 items
Fixings explicitly specified by the chosen brush maker Purchase at least 4; keep spare hardware separate from the installed count.
The reference assumes two mounting points per brush; check any different real template.
Grip pads
4 items
Four wet-area-compatible nonslip pads with secure attachment to the base Buy four 1-inch-square nonslip pads compatible with the floor and the cured finish.
Check the actual floor; a pad description is not slip-resistance certification.
Exterior wood finish
1 item
Suitable water-based exterior finish for the plywood and blocks Buy a small container whose label covers at least 6 square feet for the required coats.
Follow ventilation, drying and waste-disposal instructions. Let it fully cure before fitting pads or brushes.

- Closed footwear; keep loose clothing and gloves away from rotating cutters
04 / Put it together
Build steps
- 01
Choose brushes and measure boot clearance
Select replaceable brushes whose mounting blocks have an approved screw pattern. Put them on a bench with the bristles facing inward and trial the largest boot gently. Leave enough room that the boot can lift free. Choose brushes whose lowest bristles leave at least 0.75 inch above the base: a 0.5-inch-high tray then has 0.25 inch of vertical removal clearance.

Trial the real boot, brushes and tray before fastening the supports. The outline boxes are fitting envelopes, not simulated bristles.
Check: The selected brush spacing does not trap the boot or scrape its upper.
- 02
Cut and inspect the base
Cut B 24 × 12 from sound 0.75-inch exterior plywood. Smooth all edges and apply only a finish suitable for the actual use, following its cure time before attaching pads or brushes.

Cut and inspect the single plywood base before installing supports, finish or pads.
Check: The base is flat, cured and has no sharp veneer edge.
- 03
Cut two matching mounting blocks
Cut two 10-inch pieces of actual 1.5-square stock. Mark their centerlines and fit the selected brushes loosely on top to verify that the mounting pattern enters solid wood. Apply the same listed finish to these blocks and let it fully cure before attaching the brushes.

Cut two matching 10-in mounting blocks. The purchased brushes have not been fitted.
Check: Both brush blocks bear flat on their wooden supports.
- 04
Position supports and check the tray path
Place the left mounting block with its left edge 5.5 inches from the base left edge; place the right at 17 inches. Both front ends are 1 inch from the base front. The channel is 10 inches wide. Center a tray no wider than 9.5 inches in it. With the actual brushes in place, slide the tray in and out through the open FRONT without lifting.

Place the two supports, then trial the tray’s horizontal route through the open front.
Check: Tray has 0.25 inch clear each side; its rim passes under the bristles without catching.
- 05
Mark eight underside screw points
Clamp each support on its layout line. Mark four points centered beneath it at 1, 3.5, 6.5 and 9 inches from its end. Check that the points do not collide with brush mounting holes.

Check: All eight screws will enter the middle of a mounting block.
- 06
Fasten supports from beneath
Drill clearance through the base and product-matched receiving pilots into each block. Use the eight #8 screws, seating heads flush without cutting deeply into plywood. Inspect both block tops for accidental breakthrough.

Install the replaceable brushes
Use the brush maker’s actual template and approved fixings, with controlled pilot depths. Confirm the bristles face the channel and that no fastener can contact a boot.

- 08
Attach nonslip pads and fit the tray
Fit four 1-inch-square pads to the cured base underside, centers 1.5 inches from each adjacent base edge. Keep them clear of screw heads. Set the station on the floor, then slide the tray along the base through the open front; do not lift it through the bristles.

Check: The empty station sits flat and does not slide under a controlled light hand check.
- 09
Trial cleaning with separate support
Sit or use a separate secure handhold while trying one boot. Use short gentle motions and stop immediately if the base moves, a brush loosens or the boot catches. Never stand on the plywood wings.

Empty, clean and inspect
Remove the tray before dirt packs around the brush blocks. Brush out debris with the station unloaded and dry the base. Replace a worn brush through its original fixing points after inspecting the wood.

05 / Keep it sound
Care
After the build
- The station cleans boots; it does not provide a rated standing surface or balance aid. Use a separate stable handhold or sit down.
- Remove packed grit rather than forcing a muddy boot through a clogged brush channel.
Check it each season
- Inspect connections and hand-contact edges before use. Unload before tightening or replacing parts; replace a cracked member rather than adding a screw beside the crack.
- Brush off debris, wipe only as needed and dry with air around the joints. Store dry when the item is not in use.
If something looks wrong
- Station slides
- Stop using it and resolve the actual floor/pad combination; do not add body weight to hold it down.
- Boot catches in the bristles
- Remove the boot while seated and recheck spacing against the chosen brush projection.
- Brush block cracks
- Replace the block/brush and inspect fixing holes before use.
- Tray catches under brushes
- Stop and slide it out through the front. Verify maximum rim height 0.5 inch and lowest bristles at least 0.75 inch above the base; choose compatible parts rather than lifting through bristles.
