After my last post, you may be wondering what prompted the shop expansion. This is what caused it.

I built this Horizontal Mortiser and when completed I literally could not move around in the shop. This was built in 2017 and I just never got around to sharing it.

I was fasinated in what it would offer me in making small parts accurately and safely with a router. I researched the many that I saw on the internet and came up with this design.

This is the lower limit of the main table movement.

This is the maximum height that the table can move. It is moved with a wedge shaped sliding mechanism. Because of the weight springs were added to on each side.

The bottom half of the table moves side to side and has limit stops both on the left and right side attached to the blue T-track that control how far it moves. A metal index “finger” is mounted on the front of the table.

The top half of the table move towards and away from the router and also has limit stops attached to the blue T-track that control how far it moves. A metal index “finger” is mounted on the side of the table.

The table also can be move away from the router and up to the router mount. The router mount can also be raised and lowered with a crank attached to a threaded rod.

The one feature that I didn’t see in all the research that I did was a jig that had a table that could be tilted at an angle. That is the reason why I made mine that had a table that could be move away from the router mount.

The router is mounted on a carriage that moves up and down and can be locked in place with T-nuts and knobs. There is also a cord storage area that contains the excess cord of the router.

There is also a hanger for the collet wrenches on the side.

The router is turned on and off with a safety switch mounted on the side of the mobile cabinet.

Hope you enjoyed this project.

WOW….........you will find that very very useful. I have a vertical mill that I use like that and you can make things that you would never be able to hold and do with router or router table. Nice work on it, Alex !!

Cheers, Jim

A WOW for me too! More space is so much better when you have nice machines to work with. Your horizontal mortise machine deserved it’s new home! She’s a beauty!

One more WOW from me! And a question …

Most of these that I have seen let the router move up and down like yours does. I’ve also seen one (on YouTube, if I remember right) where the table moves up and down on a wedge like yours does. But I don’t understand why you’d want both. What’s the benefit of having the table and the router both move vertically?

RMAC …

Having a table that moves up and down would allow different thicknesses of wood to be positioned in front of the router.

With the ability to move the router base up and down you can now route anywhere the router can reach without having to move the table. Also because it’s height is adjusted with a threaded rod, the router bit can be positioned very precisely.

The table lifting mechanism is not very precise unless I added a threaded rod adjustment mechanism to my jig. Hummm … maybe I should add that … what an idea. Anyway right now table height adjuster is a quick and dirty mechanism.

Does that explain it?

I also wanted to say WOW back, but it looked no different in either direction.

Love it ty’, sitting here with a big red (vino) thinking of ways I might be able to use it and though it has a smallish footprint formulating a tenure in the workshop.

That tilt option surpasses any level conjecture.


... a threaded rod adjustment mechanism to my jig. Hummm … maybe I should add that …

Ho-hum, No Hummm... would make a up lifting addition… and should be looked at now, before the creativity juices start to ebb.

Any SU?

That is quite a machine. It is one of those things that I can think of 20 ways to use it but know full well there are 100’s I can’t fathom.

Does that explain it?

tyvekboy …

Sorry, I’m still not seeing it. I’ll explain my thinking and maybe you can tell me where I’m messed up.

When the router is at its lowest position, I’m assuming that there is a table position that puts the router bit at essentially the same elevation as the table surface.

Starting from that condition, it doesn’t make any sense to move the table up because doing that would put the router bit below the table.

So what happens when you move the table down? It’s true that moving the table down lets you work on taller work pieces. But couldn’t you get the same effect with a stationary table by just making the router tower taller so the router had more upward range of motion? Was there some reason you couldn’t (or didn’t want to) make the tower taller?

Congrats, thats quite a build.
I tried to make a horizontal mortiser once (much simpler) but it failed as the slides I used had too much play in them causing poor milling.
What do the moving tables ride on?

Looks like a great build.

Please be sure to show us pics of the joinery you make with it.

Rmac—I’ll try to post more photos later in the comments to show what I’m trying to explain.

Unclearthur—I’ll try to add more photos to the post showing what I used for the table guides. The lower one is a modified drawer slide and the upper one is made of plastic. WATCH the project and it’ll appear some time today if I have time.

Mainiac Matt—Like a mortising machine that’s hardly used unless you make a lot of furniture or projects that need mortise and tenon joints, this is one of those machine. I hate to tell you that since I’ve built it, I haven’t had a project that I needed it for. It’s still a virgin machine …. lol.

Tyvek,

I will follow this post. Interesting and complex build.

I agee a video of this machine in action is warranted.

I was really impressed with your copper anniversary rose, but I’d be even more impressed to receive this jig from my husband for our anniversary!
