Figuring where to place the lead is easy if you have a scale. Measure average DW on sample sharps and naturals. The difference is the amount of back lead to place in the naturals. If the sharps measure 58 g DW and the naturals 52g, 6 g worth of back lead is required (-6 FW) to bring them up to 58g. Measure and note FW average on a few naturals. Tare the scale and locate a lead behind the balance rail until it reads the difference. I have found it to be 6 g usually. If the average FW on the naturals was 11g and you lightened them by 6 g, the new FW is 5g. Place A0 and C8 on the scale and locate one or two leads behind the b/r to effect 5g FW. Attached is a photo of an eyeletter which I purchased from a used tool store (gotta love these places). I can adjust the length of the plunger to swage the lead efficiently. Drilling and swaging: 45 minutes. In shop, keys removed that is. -- Regards, Jon Page -------------- next part -------------- A non-text attachment was scrubbed...
