Short Stop.
The side bracket does need to be made from heavy gauge steel. If not said carriage forces will make the top of the bracket twist! As happened on my first efforts. To eliminate the problem I have used corner brackets obtained from Focus DIY, 5 mm thick by 20 mm wide and 90 mm long, which I cut to size. A further piece was cut from the corner brackets to act as a packer between the tube and the fabricated side bracket. Bracket and packer are welded in place at the ends of the tube along their vertical edges only.
To make sure that the tube sits flat on the underside of the chassis the packer needs to be filed flush with the top face of the tube. And the same goes for the packer and end of the bracket with respect to the bottom face of the tube. When all is welded up there will be some holes in the brackets – the pre-drilled attaching holes as found on the original source bracket. Fill these holes with car body filler.
When attaching the side brackets forget using bolts. There is considerable force exerted by the carriage when it hits something. A bolted assembly will be forced out of alignment – as happened on my first efforts.
If you are using the WoodRat plastic jaws and are not using the micro adjuster then you will need to undercut the inner facing vertical edge of the Left Hand bracket in order to achieve proper contact of the stop with the carriage. This is because the plastic jaw overhangs the end of the carriage, thus preventing the metal stop contacting the end of the carriage.
