Reglus drill jig. Extremely expensive bit of Swiss kit. Highly versatile, amazing quality. If you are drilling shafts etc for taper pins, split pins etc., it is superb. See their website. Occasionally for sale on ebay!

7 traction engine grate a

Not a jig or fixture but best thing I ever made for the Burrell – a stainless grate with removable stainless bars.  Years old and no degradation to the bars at all.

Rail Drill Jig 2a

Saturday 25th July 2020. Decided that the Clubs drill jig for the 20 x 10 rail that we use was getting a little tired.  The end result was as pictured above.  The drill guides are from 0.5″ silver steel hardened by heating to red and quenching in cold water.

Rail Drill Jig 1a

Drill Jig from the back.  The length of the short piece of bar rail can adjusted to give a small gap between the two lengths of adjoining rail to allow for expansion. The short piece of bar rail can also be removed for the drilling of fishplates.
