MLCS biscuit joining system makes strong joints easily and inexpensively!

MLCS Biscuit Joining System
Use water based glue (carpenter’s glue) in the slots. Insert biscuit in slot and compressed biscuit expands as moisture from glue is absorbed.
  • MLCS Biscuit Joining System

  • Reviews
Biscuit joining is one of the strongest, fastest, and most accurate ways to join hard and soft woods, plywood, composition board, etc.

We've developed a method for precision biscuit joining... without using a biscuit joining machine! By using our carbide-tipped 5/32" or 1/8" slot cutter , you can join corners (frame joining & mitre joining), edge to surface (butt joining & T-joining), and edge to edge. Use Item #5155 spiral upcut bit to cut slots in the center of the board which would be beyond the reach of a slot cutter.

Biscuit Joinery Instructions (PDF)

  • Reduces joining time. No need for precise measurements or jig set up
  • Eliminates bothersome woodworking tasks like nailing, screws, rabbets, dados, dovetails, dowels, mortise and tenon joinery
  • Makes much stronger joints than doweling
  • Aligns joints easily
  • Guarantees perfect joints every time
  • The router bit’s ball bearing guide controls exact depth of cut for precise biscuit placement
  • Q: Does the router bit make all biscuit joints?
    A: Yes. MLCS Biscuit Kits can make all the joints a machine can, including edge-to-edge and edge-to-face corners, plus some joints that machines can’t do, such as face frames and narrow rails and stiles.
    Q: When making a biscuit joint, do I plunge the bit straight in like a biscuit machine does?
    A: Yes, but you need to stretch the slot just a bit so the biscuit will fit. Mark pencil lines on both boards (see photo). Plunge into the wood as usual, then move the router or the work about 1/2" to lengthen the slot. This does not affect the strength or alignment of the joint since the critical dimension (5/32" or 1/8" thickness) is maintained. Here’s an easy technique for joining long boards: Run several 8"-12" long slots in each board with a slot cutting bit, then place biscuits along the length of the slot.
    Q: How about joining frames, or rails and stiles?
    A: The best choice is the #11 round Biscuit Kit. The round biscuit is slightly deeper than a #20 and can join a frame down to about 2" wide. For really small frames and mitres, the H-9 Set is perfect (down to about 1-5/8" wide)
    Glue Injector: Put the glue in biscuits slots cleanly and quickly. Use water based carpenters glue.
