I agree, it's intimidating when you open the box and look at the instruction book. Thair are more parts in "one" rail car-truck, then in the gun barrole and chasie combined. That's why I did the gun barrole-first. The chasie secound, and -then-whent back to the first page of instructions, and started the rail bed. I lined the barrole with one section of aluminum tubeing, sleaved in evergreen tubeing, from muzel to breach. Then led waights to the breach to compensate for the waight of the barrol---did'nt quite ballance, but the sholder pivets are tight enuf to make up the difference.
