Just bought a Grizzly G3183 mortiser off Craigslist—it’s a few years old, but i got it for a good price. I’ve read a number of tips on the net about how to setup a mortiser, so I’m good for the general stuff right now. My concern is from a review of the G3183 and almost all mortisers from that period from American Woodworker. I don’t have access to the whole article. It that concluded this:

“The hold-downs on these machines are a disappointment. The problems were so obvious and our fixes were so simple, it’s puzzling that no manufacturer has bothered to come up with a better system. At the very least, the manufacturers should include a section in their owner’s manuals titled something like “Getting the Most Out of Your Mortiser” that would show how to make these improvements. We bet most woodworkers would be willing to pay more for a machine that they didn’t have to mess with. Because none of the machines was able to consistently cut 1/2-in. mortises without additional clamps and fences, we’ve decided not to give an Editors’ Choice award. We’ll wait for a basic machine with a hold-down system that’s effective through the range of its capacity.”

Anyone have any idea what specific steps they’re speaking of? It looks like this:

If that little black u-shaped thing is all there is for a hold down there are probably many many better ways to hold your work down. You could use toggle clamps, regular c-clamps, just about any manner of clamp with enough clearance to hold the work safely without getting in the way.

HTH,
Mark

Thanks a lot, Mark. I’m just starting to mess with it today.

I’ve only used a mortiser a few times and found that sharp chisels and good hold downs make the job go much smoother. Hope it works well for you.

Have you considered a cross-slide vise to hold the stock?

Clamping a workpiece in there is more complicated than I thought. I suppose when I’m using real dimensions, it will work better, but on scrapwood there were some really awkward setups.

The Woodwhisper has a really good video about mortisers and how to sharpen the chisles. The video is episode 151 “Mortiser? I hardly know her!”

I’d seen the wood whisperer video.

Scott, what a slick vise jig. i’m going to look into that. That seems way more secure than the stock setup.

@Scott, my local woodworking store has one of these Shop Fox 3 inch cross-slide vises. What’s the advantage of going with the Grizzly 4 inch one?

That vise would ruin your vertical capacity. I have a similar Delta model, and it will only mortise a 5” wide board.
Some benchtop mortisers have improved hold downs by adding roller wheels. They ride in tracks in the base, and help hold the workpiece tight against the fence. The advantage there is the workpiece will still slide left and right. The Steel City and WoodRiver mortisers come with roller wheels, but I don’t know a way to add them unless your machine has tracks. A magswitch accessory perhaps?

Willie, are you speaking of the Shop Fox vise or either vise? It only works with a riser box like this:

Okay, now I see what you mean. That could work. It would make a benchtop model work more like an upright floor model.

I think the 3” vice would work too.
Its not my idea, I just have it in the back of my mind to upgrade my mortiser with one.
