Would you believe it; you wait for several years for a source for Tommy Blinders and then two turn up at the same time!
Having had a Tommy machine for some time that was missing the Blinders assembly (but it did have the servo controller board), and being unable to source the elusive blinders I decided to design and manufacture a replacement. I am qualified in electronics, software and mechanical engineering so felt confident in getting a solution that would work.
Work started in December using FreeCAD and after a few prototypes and lots of testing I have a very solid working solution comprising of the mounting base plate, top blinder, bottom blinder, arm, servo and return spring. They will be supplied as a complete working assemble; just attach to the the playfield, plug into the servo controller (available from Marco if you do not have one), adjust and you are good to go. Please note that this is a complete redesign and as such the part are not compatible with the original design.
It is pure chance that my blinders mechanism and the excellent looking solution from biglebowski have appeared at the same time. We are not connected in any way and both solutions have been developed individually. What do they say about buses!
Please find below a few images of the blinders and assembly.
They are currently on sale on Ebay at http://www.ebay.co.uk/itm/322004812189?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2648
