Rough and Ready Rack and Pinion

[agr]

While working at a grain processing plant leading up to the Xmas break, I came across a simple, clever idea the fabricators had used for providing a rack & pinion arrangement on the discharge doors of the grain silos.

Essentially, the rack was formed by welding a length on chain to the slide gate (or two lengths in the case shown in the attached pic), standard sprockets can then be used as the "pinion".

I don't know if this is a common practice which I am only seeing for the first time, or just one more example of ingenious "farm" engineering, but it is definitely a solution I hope keep locked in the ol' memory banks for future reference.

Now that's a neat idea

It has been around for a while back in the early 70's I worked in a machine/welding shop where we worked on and built a lot of farm type machines and I seen it used then. I would like to take time to wish the best to everbody for the next year.

You can buy timing belt in long lengths and do exactly the same.
many routers run on this system, it cheap and very accurate.
