Business
Door-jamb undercut and flooring transitions
Offer a focused service to undercut door casings/jambs for tile, LVP, or laminate installs and to flush-trim baseboards and transitions. The Starlock mount speeds blade changes on site, and the bi-metal edge handles surprise nails in old trim.
Reclaimed lumber prep and resale
Source reclaimed boards, use the bi-metal blade to flush-cut protruding nails and staples, trim ends square, and bundle cleaned, ready-to-mill stock. Monetize by selling by the board foot or curated project packs.
Realtor and landlord punch-list service
A mobile finish-carpentry service that quickly clears minor issues: flush-cut protruding fasteners, trim shims, remove/replace trim cleanly, cut neat drywall access panels, and tidy up problem spots before listing or move-in.
Deck and fence fastener flush-cuts
Specialize in trimming or removing protruding nails/staples, replacing damaged boards, and making tight, flush cuts near posts and walls where circular saws can't reach. Ideal as an add-on for exterior maintenance contracts.
On-site cabinetry and built-in adjustments
Provide scribing and flush-fit modifications for cabinets, shelves, and panels. Make tight cuts in place, notch PVC backers or toe-kicks, and flush-trim end panels for appliance installs or remodels with minimal dust and vibration.
Creative
Reclaimed wood + metal inlay wall art
Harvest nail-ridden pallet or barn boards without fear of hidden metal, then plunge shallow grooves for copper or aluminum strips. Use the bi-metal blade to both cut the wood and trim metal inlays perfectly flush, creating geometric mosaics with mixed-material accents.
Hidden-magnet knife rack or key holder
Cut 1/8–1/4 inch deep recesses on the back of a board to embed neodymium magnets, then flush-trim a thin wood veneer cover. The shallow immersion depth helps keep the pockets consistent, and the low-vibration Starlock mount preserves clean edges.
Salvaged-trim picture frames
Turn reclaimed baseboards or casings (even with old nails) into unique frames. Make precise straight and flush cuts to splice lengths, then flush-trim spline or dowel plugs and any nail remnants for a clean, character-rich finish.
Butterfly-spline charcuterie board
Plunge shallow mortises for decorative bowtie keys that stabilize small cracks in a cutting or serving board. After gluing, use the segmented edge to trim the splines perfectly flush to the board’s surface.
Shadow-box diorama with crisp cutouts
Build a layered shadow box and use the blade to plunge precise openings in thin plywood, MDF, or PVC backers for windows and lighting channels. The reduced vibration helps maintain clean edges on delicate parts.
