Scot Laughlin's Custom All Weather 2260

2260 with short crosman receiver atop a mini riser made from aluminum tube. Barrel is a 2200 soda straw
tensioned inside a titanium golf club shaft. Three screw mod to the trigger, bulk co2, SSP 250 rear cocking
striker assembly. Factory stock, reshaped, bedliner finish and stick on cheek piece. The idea was a weather
resistant light hunter for rainy days.
I've got a Cothran stainless receiver and gas tube waiting for me to get back to this one.

Response to investment casting ( real world term) nt

Extruding is exactly the correct term and it works ALMOST exactly like the Play Dough FunFactory. An aluminum billet approximately 6" in diameter 3' long is loaded into this big hydraulic press it is heated but not to melting... The die is inserted into the machine and it squirts out the desired shape... Investment casting usually involves making a mold, casting a positive of wax, inspecting wax positive for voids, defects, etc. And if all is good the positive is made into a mold and when the metal flows in the wax is melted out and the metal fills the void... It is also called 'lost wax' method... It is called investment casting because it is a sustantial time and effort to produce parts this way.. It is cheaper to cast a 'Bad Part' out of wax than metal.... Greg
