Thread: Leigh Jig result (better pics this time)

Very nice. Neat and tidy.
Which brand router bits did you use?

I used two of the three standard Leigh bits that came with the jig. I used a Makita 3612c (variable speed) half inch router with the 8mm collet reducer which also came with the jig.

Good work, looks great. You must be pleased with that effort.

Hi Matt,
what is the thickness of the inlay?

Les

Hi Les,
The tail and pin boards are 16mm and the inlay board is 19mm thus making the inlay 3mm. It is vitally important that the thickness of the two shims used in the machining process is exactly the diffence between the pin/tail board thickness and the inlay board thickness.

i.e. For a desired 4mm inlay thickness:

-Pin and Tail Boards would be 12mm thick
-Inlay Boards would be 16mm thick
-The two shims used would be 4mm thick

Instructions can be downloaded from the Leigh site and I am happy to answer any other questions you might have.

Cheers, Matt

Thanks Matt.
I have the document. It was more my curiosity of what thickness of inlay would be pleasing to the eye.
Did you use the 1.15 factor for the thickness of the shims?
Regards
Les

Yes I used the 1.15 factor. I don't think it would work unless you did. I have just had a go at making a box where the dovetail at the top of the sides is 4mm wider than the rest to allow for the 4mm kerf of the table saw blade when I cut the lid off. In order to do this I set the jig as if I was doing an asymmetrical joint. I.e. setting up both ends of the jig with a mirrored set up (using vernier calipers to match the distances between the guide fingers at each end. But it didn’t work. It was close, but not good enough. I think that perhaps in my initial set up of the jig out of the box, I may have set the right and left side stops on the vertical face of the jig incorrectly?? Back to the drawing board with this one!!

OH Looks like I had better start saving.
I am a beginner at woodwork ,but like accurate things
Thanks
Now I have to talk to the
Minister For War And Finances again.

Aussie, I found that the Leigh Jig was great value. It does everything I want it to do straight out of the box!! The instructions are brilliant and the jig is of very good quility and after intial set up, it's simple to use. The three cutters supplied do a whole range of joints and you are only limited to the max and minimum thickness of timber you can use with the supplied bits. However, addition bit sets are available as are extra templates which allow you to do much more intricate work on thinner timber. I use mine all the time. Once the timber is machined to size, I can cut the box joints in all for sides in around 8 minutes. Quick, convenient and repeatable!!

Here is the test piece for the asymetric setup.4mm wider dovetail on the right hand side. The inlay section is not even on both sides?? Any help...

Spectacular, Matt, well done. My scrap never looks as good as that !

Cheers

Hey Matt.
I recognise that type of timber mate.
Your not in the box challenge with that thing are you?

perhaps.........

I checked the list for the box challenge.
Your not on it.What a shame.

I still have a chance.
