One of the nice features on the older New Zealand locos is the Splashers. These were 1/8"thick with a brass tube beading finished with brass knobs each end. ![](https://i.ibb.co/f1w9SQc/1.jpg) ![](https://i.ibb.co/y4d6GyT/2.jpg) How to edge a steel strip? In the flat or after rolling? I decided to slit some 1/8" brass tube and push it over the edge of the strip. This would ensure the brass bead was accurately aligned on the edge of the steel. But could the tube be rolled after slitting? To cut the slit in the tube a little keyhole guide was made and the tube pulled through the slitting saw by hand. You have to push it to start off and then grab it with multigrips to pull it all the way. Looks hairy but it works! you can make 1/2 round the same way... ![](https://i.ibb.co/Jmp0WMh/3.jpg) ![](https://i.ibb.co/Bt2j9Zr/4.jpg) OK so once cut, the tube pushes over the edge of the steel strip (which is intentionally the same thickness as my only suitable slitting saw BTW) ![](https://i.ibb.co/3Fk4L5C/5.jpg) And cleaned and soldered in the flat. ![](https://i.ibb.co/zHsHcn6/6.jpg) Using the wire rolling groove in the rollers (this is the small Chinese 3 in 1 tool which has been surprising useful at times) both steel and brass rolled together to the required radius. ![](https://i.ibb.co/G32Szwp/7.jpg) Finally cut to length and brass balls attached. Something was off with my scaling because the first one looks a bit large. No problem to shorten and close up the radius to to suit ![](https://i.ibb.co/zScRswT/8.jpg)

That is neat! I have to remember your setup to slit tube, that is really a good idea.

They look just like the prototype. Excellent.
