Sear pin ...
No, the Ermes won't fit. The drawing you did above is not correct, because the sear rotates through the center of the pin, which means, that if you increase the pin and sear hole at the same time, you did not change the pivot at all. But if you feel like doing that, I strongly suggest that you find someone that has a lathe and stainless steel suitable for making axles. They can make you a new pin that will fit like a glove and will solve the problems that you currently have with the gun 100%. I increased the hole size because I used what I had at home as a proof of concept. Then I had my neighbor machine me a new axle from Inox/stainless steel.Anyone able to check whether ermess sub fits?
Mario is super slow to reply, but my guess there is noone compatible
For sure the Sampson as a eurogun on steroids is based on the Hurricane "Corsair" as the Hurricane dates from at least 1949 when it was displayed on the rollergun patent using a cocking lever. That would mean the "Corsair" is actually even earlier than 1949. The Sampson appears in the later sixties.Jack Prodanovich, one of the great contributors to the sport of spearfishing and heavy equipment design for shooting big fish rather than tiddlers soon recognised the importance of curve matching in his trigger designs. He had been making guns when the sport was just beginning and his mechanisms were built using grinding tools and jigs to get around meshing problems. That meant his two piece trigger did not drive the mechanism backwards because when cutting the trigger profile the trigger piece revolved on what was the trigger pivot, the holes being cut first and all the shapes generated with respect to the holes. He knew that even the best designed forms were no good if the holes were drilled slightly out of position or they did not match the pin spacing in the housing in terms of lever separation in the housing.
One gun that was notorious for pushing the trigger mechanism backwards was the Sampson gun, a gun for big hitters that was based on an up-scaled and redesigned French Arbalete on steroids. The French gun also pushed the spear back slightly against the band pull, but mitigated it with a curved sear tooth profile engaging a matched spear tail notch whereas the Sampson had a V shaped tooth and spear tail notch. The curved notch “euro tail” is still with us today.
