Thread: Mortice Jigs

Well go on then give us some details about it as I for one would be very intrested in being able to build something like that instead of forking out the big delero's for the "known" brands.

Munchkin,

Do a search for Rocker's mortise jig on the forum. Also, the new edition of Australian Woodsmith mag has full plans for a very flexible Mortising Jig.

Cheers,

Mate,
that's nothing, I'm using trained and CNC controlled termites :eek: , no noise no dust and once I set them to work I can get on with other more important things (like doing quality control on my neighbours home brew kegs )

So Mick, trained termites huh. I'll bet the little buggers dont stop on command

Wayne,

I have had a look at the Woodsmith morticing jig, and feel that, while it would take just as long or longer to construct as my jig, it does not offer the micro-adjustability and built-in measuring facilities of my jig. The Woodsmith jig no doubt does a reasonable job; but if you are going to put in that amount of effort to make it, you might as well aim for precision as well.

Munchkin,

If you send me a PM giving your e-mail address, I will send you an article containing plans of my jig.

Wayne,
still ironing out the "bugs" (pun itended). It's hard setting microswitches for the "stop" function and I've ended up with some beautifully made mortices that go strtaight throught the workpiece and through my benchtop :mad:

Mick

Rocker, Thank you very much for the info on your jig. Very thorough and complete. As I have access to a metal working CNC and some scrap aluminium what parts do you sugest I could substitute for metal?

Again thank you for your help.

My mortice Jig

I am attaching a photogragh of the jig I use to do my mortices made with MDF. As I previously mentioned I was able to complete 16 perfect mortices in 20 minutes, this of course has come about by edperience and familiarity usuing this jig. More pics are available if requested

Munchkin,

I am not familiar with with metal-working CNC, but I imagine you could make all the flat parts, except perhaps the vertical support, out of 6 mm thick aluminium sheet and aluminium angle, and tap threads in it for the locking knobs. I am not sure how smooth you could make the dadoes for the guide bars in metal, so it might be best for the fence to be made out of wood.

Anyway I shall be very interested to see an aluminium version of my jig when you have completed it.

Rocker

Hi Rocker


I would like plans of your jig please - I'm about to make a complicated slat bed which will have HEAPS of mortices.

Munchkin,

On further consideration, if you make the horizontal platform for my jig out of aluminium, you would need to use a different method of locking the stop-blocks, since you have to avoid anything projecting from the underside of the platform which might interfere with your workpiece. Maybe machine bolts with countersunk heads engaging with female-type locking knobs would work.

John,

Your morticing jig is simple to make and, for your purposes, mainly making garden furniture, where minor inaccuracies are not a problem, it should work fine. However, it has no provision for ensuring that the mortice will run parallel to the face of the workpiece, and you have to rely on centring the router bit over the marked out mortice by eye, when setting the fence. My jig eliminates the need for marking out the mortice, and ensures considerable precision, but, of course, it takes quite a bit more time, say a day, to build it.

Rocker

Hi Rocker,

Thanks for the competition, my easily constructed jig will produce accurate parallel mortices if required, I would use the calliper depth rod and push it up against the jig fence, the measurement required would equal half the width to the router centre point plus the measurement to the centre mortice point.
However I do agree with you also that your equipment is very attractive and you certainly produce some very fine pieces of furniture as I have personally witnessed.
