Billet Nylon Hammer with unique stroke adjusting ... M-rod

[Motorhead]

* This hammer for a REGULATED application *
  More custom work with a big tip of the hat too Bob (   rsterne ) for sharing a design idea that I promptly manufactured specific for my regulated M-rod.  See: http://www.gatewaytoairguns.org/GTA/index.php/topic,39387.msg367747.html#msg367747

Outer hammer material is MDS "Molybdenum Disulfide Filled Nylon" which has very high anti wear properties and self lubricating.
Inner adjustable portion DelrinŽ acetal resin.
Both pieces thread together on 5/8-18 threads that happen to be quite a snug fit ( a good thing )
Within Delrin portion a S.S. 1/4-20 screw acting as striker button on valve stem and it's head a centering spud for hammer spring.
*It's threaded in with RED grade loc-tite permanently fixed. Turning it's 3/16" cap screw head rotates the inner part independent of hammers outside which is held from rotating by the cocking lug/screw indexed in slot top of receiver. 

* Previous testing showed +/- 28g as ideal hammer weight ... this one right at 27.8g 

With this design as hammer travel is reduced or increased, the Hammer spring Pre-load DOES NOT CHANGE
