A JDS MultiRouter, horizontal mortiser, vertical mortiser, router, Leigh jig mortise attachment, router, and drill press & chisels. The JDS gets used the most followed by the vertical hollow chisel mortiser for when doing square mortises. The horizontal when doing very large mortises.

Thanks for all the responses; it seems, much to my surprise, that the majority use mortising machines. As I don’t have the budget or the space for a mortiser at this point I’m going to work on doing mortises with a router…I have a few projects coming up that’ll give my router-mortising skills a workout.

Until recently I have completed all of my mortises either with a chisel or with a router. There are some really good, very simple jigs out there that can make the task easy. I saw one recently on YouTube by Gary Rogowski that I thought was especially good.

Delta benchtop mortiser. The mortiser and the Unisaw are 2 of my favorite tools in the shop.

Yeung Chan’s mortise & tenoning fixture always looked great to me by the way, but I never got around to building it:

manitario…the cheaper dedicated machines have a VERY small footprint on the bench (I use removable blocks to extend the table for that very reason…the supplied table is not big enough for my limited abilities). I just checked and see that the Delta “pro” is still under $300 and comes with 4 chisel sets.

They are essentially modified bench top drill presses and come with 2 of the flaws of the DP mortising attachments (flex and material movement) but without what I think is the biggest complaint (set-up and taking the DP out of service). The dedicated machines can do mortises fast. I’m guessing a plunge router does them better but I’ve learned that perfection is relative in mortises (minor flaws will rarely get seen).

I have a cheap mortise machine and the bits are always getting clogged with chips even when I go slow. So now I use a dowell-it jig and drill out the bulk and sqaure them off with my cheap mortise machine.

I use a DIY shop made horizontal mortising machine. I started with a Greg Paolini design and added an integrated dust collection system as well as adding a lift mechanism. IMO, this is very accurate and repeatable when making either mortises or dados in small pieces/frames. I have dado’d up to 30in with this.

Closer view of dust collection. You can see one of the DC slot openings to the front side.

MDF cover over the DC channel. This way I get DC across the entire front side, below the router bit.

Adjustable dust baffles work great and they help channel shavings into the DC chamber slots.

Some examples

I use the Paul Sellers bevel chisel method. I’ve used routers and templates, too. This is quieter.

I just use my router either hand held or in the table. Quick accurate and done.

For my tenons I just take a rasp or my spindle sander and round the edges of the tenon until I am happy with the fit.

I don’t usually have tons of them to do, so that way works fine for me without buying a separate mortiser.

I use a mortising attachment on my drill press. Once you get it set up it does a good job.

Have your say...
