A question was raised regarding the reverse glue joints I used on Edna’s Kitchen Workbenches.
To best address this question and the fact I had off cuts remaining I decided to add it as a blog.
The reverse glue joint is exactly that .
Reverse. A matching profile is cut on each piece to be joined simply by reversing the timber before cutting.
Glue. The joint is designed to be fixed by glueing.
Joint. Its one of the many joint methods available to join timber.
However, as with any joint a setup procedure is needed for the cutter, so using piece of timber of the same thickness the exact center is needed to be found.
The separated pieces with blue dots are the test pieces and the sections underneath is a end off cut showing a cross section of the joint.
Your initial eyeball can be used to determine the approximate center then setup cuts are made with any fine tuning adjustments are made to ensure an exact fit.
Then its a matter of cutting all the profiles
Apply glue and clamp up, as the joint closes it also self aligns.
This cutter is capable of doing RGJ in timber from 12mm to 40mm
You do loose some width with this method as opposed to T & G or biscuits, but the glue surface increase and the fact they self align perfectly is a benefit.
