« Part 1: Basic Jig Features Part 2 of Leigh FMT PRO From a Users Perspective series no next part

The heart if the FMT, I suppose, is the snap-in guides. That’s what determines the mortise and tenon size. You only need one guide and one bit to rout both part of the joint.

To remove a guide, retract the button and push the guide out through a finger hole in the table.

The sled follows the guide to form the joint. You can hold the router handles to cut the tenon, or you can hold the sled handle with your left hand to guide the cut.

The clamps probably deserve a closer look. They do hold the workpiece quite securely.

What keeps them from sliding around when not in use is the knurled knob. They stay in place as you loosen one workpiece, and replace it with the next workpiece.

The left guide pin is adjustable for joint fit. It rides the guide to form the specific joint you’re making.

The guide pin is tapered underneath, and either follows the perimeter of the guide (tenons), or rides in the slot of the guide (mortises).

The carbide bits in the optional accessory kit are impressive. They cut very clean shoulders in white oak.

To test how cleanly the bits cut, I cut a mortise that exited a workpiece on the side. This is obviously not a cut you would normally make.

I was amazed how clean the mortise was, despite having no backup at the exit points. Again, don’t try this at home. I just thought it was a cool looking cross section of the joint.

More to follow in future blogs including angled joints and avoiding potential pitfalls.

Looks good. You did a great job on the joints. I have to look in to that product.

Your photos look I’m looking at a commercial for Leigh.

Well done.

I’d also be interested to hear what current users like about the jig, and any issues they’ve had.

I’ll be reading along. I’ve had a fair amount of experience with the FMT Pro

I’ve had mine for over a year now. Really have no complaints. I’ve sometimes used a one inch travel dial to “tweak” in the cross hair locations.

I’d love to see what you use for a travel dial. Low tech or otherwise, I’d be interested to see what you came up with.
Thanks

A lot of the time the cross hairs are good enough, but sometimes I’d like a more precise way of “tweaking” in the location ( centering) the mortice and or the tenon. I’m a retired tool and die maker and I sometimes go overboard on precision, so what I did is this. My FMT is mounted on plywood. To this I attached a piece of flat steel for a mag base to stick to, and added a one inch travel dial to that. This allows me to adjust the top plate in .001 – .002 increments to insure things are perfectly centered. Here’s some pics.
