Simple jig for cutting circles with the OF-1400

[Enrico74]

Hello,

I had to cut a circle and tried to figure out how I could do this with minimal effort.
I came up with a very simple DIY jig that attaches to the guide rail adaptor of the OF-1400.
I made it from a scrap piece of MDF (22mm thick).

I drilled two holes for the pivot point, one that accepts a 4mm screw and a smaller one for a nail.

Have a nice woodworking day !

I made a similar jig from aluminum.  The hole for the guide pin bolt in in the center but it doesn't really need to be.  And I used the fine adjuster screw from the guide rail adapter.  And I have two screws to lock the aluminum block down on the bars but you probably don't need that.  But it's nice to get it all locked down.  Photos here:
