Odd Yale 805F and any advise on repairs - (photo heavy)

[Doug MacQueen]

A couple years ago I went on the search for some new spring stock supply. I purchased the few that I could find available to the lock trade and one from Brownells, the gunsmith supplier. Not surprisingly, it appears that very little is currently available in flat stock. In the past you could get a selection of various thicknesses in different widths. Those days appear to be gone. That ESP selection on eBay does give you different widths, but it is all the same thickness, about .023". Other thicknesses are available by the roll from sources like McMaster Carr. Because of this situation, I think your best bet is to search out older locksmith shops that have been around for 50 years or more, as they may have what you need. Mic the the spring you have and give them a call.

Mea culpa, I was unaware that those were all the same thickness. The assortment I have had for many years came from Ajax Wire Specialty Co. and is their No. 151 which contains 100 ft. of assorted widths and thicknesses of flat spring steel in 12" lengths. See thumbnail image attached, click to enlarge.

You could check with them and see if it is still available and where it could be purchased. I do not see it on their website but in the alternative perhaps the No. 149 would be satisfactory:
