PARALLELOGRAM - CENTRE LINE MARKING TOOL

The reason I made this tool is that I found the two post type slips off the board at the end of the board and this one stays on centre because the cheeks guide it past the end of the board and it has two marking pins to allow the marking from end to end .
The tool aligns itself to the faces of the board by squeezing if together against the board and the hinge action brings the marking pins into the centre of the board .
Just a quickly made tool from some shop scraps and four flathead bolts threaded into the cheeks and two screws with brass ferules in the hinge bars . I used 5/16” flathead bolts to give a better bearing surface and it is easy to remove any play in the mechanism and a little wax in the countersunk holes and on the contacting surfaces makes it operate very smoothly .
This one adjusts from 1 3/4” to 0” in thickness which I think is quite sufficient for most applications .
I can also use this tool as a centre finder on the end of a square and may make a larger version for marking larger square objects instead of marking with diagonal lines .
A easy build by using a compass and the drill press with a fence and stop blocks to archive the required accuracy .

Very nice alternative to the traditional two post version. It is a small nuisance to loose your reference point the last 1/2 inch or so when you get to the end. Thanks for sharing and be safe!

More tools and specialty tools are a must in any shop. You may only use it every so often, BUT you have it! Good job.

I remember Steve Palm told someone here one time “you got a good thinker”.
If I may borrow his thought, it applies perfectly here.
You took a simple, very useful tool and fixed the only one tiny flaw it had, proving that just because it ain’t broke doesn’t mean that you can’t fix it. :-)

...... A great tool made even greater.

Good one Klaus.
