Today I worked from 8:30 until 5:15 on these %^$$#& sliding windows. After almost 9 hours of work I got one done. I thought forming the window channel was bad but everything after that was worse. The bottom edge of the inside garnish moulding is supposed to hook over an angle that is riveted to the sill. There is no way this can happen. The riveted angle ends up tight against the window channel and there is no room for the moulding to hook over it. Drilled out the rivets and bent the angle hoping to gain enough room for the moulding, riveted the angle back on to the sill and the moulding still doesn't fit. Did this twice. Finally said the hell with it, chucked the angle, drilled 3 holes in the bottom of the moulding and screwed it to the sill. How they did this in 1949 on a moving line beats me. Not looking forward to the other 3 windows. Somebody tell me what I am doing wrong. There has got to be an easier way. Weeds
