david brown hydraulic setting valve chest tool 961796 special.

I’ve recently made a few of these after I found it was impossible to get them

They are Cnc plasma cut in 3mm steel

The two critical dimensions are set and reamed to be a slide fit on the arm good tight fit

I’ve tested against an original and all match the fine

I added a little clearance on the bit around the casting as it may vary

Cold blue coating for dimensional accuracy and surface protection
