Screw advance box joint jig

[Oran]

First I have to give Matthias Wandel of http://woodgears.ca/ a mention as I have to thank him for introducing me to this very useful woodworking technique.

If you want to know more about the jig, Matthias is the best person to explain how they work. Sorry about the English I'll let the photos do most of the explaining.

My jig was built using only hand tools and all of the wood is reclaimed and a lot of it was washed up on the shore. It’s not built to the same standard as others I’ve seen on the internet but it can still achieve a reasonable accuracy.

I had to modify the design to make use of what I had. The screw is an M16 x 2 threaded rod which means it moves on by 2mm for every turn. I cut a thread in the first block of wood as the nuts provided for the rod are a loose fit. The dial is marked out in 10th of a mm which is all it takes to make the difference between a tight and a loose box joint.







If the wood is turned 90o it is possible to cut tenons. This was useful for the first project I did which was a jewellery desk.





Some box joints I cut for another project.

I saw those gigs a few years ago... The link is in my favourites since then! Mr. Wandel is a real artist/genious !

And you Oran, don't stop to amaze me with all your projects!

I’m a fan of Matthias’s videos and always look forward to the latest one on Sunday. He has an amazing ability to combine engineering and woodwork which is what appeals to me.

When the evenings are longer I will post some more of my projects.

This is how the box joints turned out once glue together and sanded. The project is something I was asked to do by someone who wanted a wooden surround to improve the look of a storage heater. I’m very pleased with the results and the joints are nice and strong as well.

Did you try the finger joints? My favourite since I saw his wooden crates he made!

You are a skilled man! What tools do you use in your shop for woodworking?

I haven’t tried finger joints yet but I’m sure if I needed to join 2 lengths of wood end to end it would make a good job of it.

My own workshop has only a basic range of hand tools for woodworking as I have no electricity supply. I should maybe do a workshop tour post one day.

The table saw I used is in a workshop where I work. I don’t really do much real woodworking it’s unusual that I have had some projects recently.
