Head Scratcher???

[Schu]

Hey guys! I have about 3-4 machines that all do this and I need a little help. When the dist. will be delivering the head pin, the head pin will bounce just right, and end up standing straight up in the bin...so that when the next set of pins comes around (assuming there was no strike bowled) that next head pin, pushes the first head pin ASS first into the cups, creating one hell of a table jam...Any ideas on how I can adjust or correct the bin, pin guides, or #1 bin so that this does not happen anymore....????

Hey Swiss Miss Kris!

1. Even when shock mounts look fine, they can be shot. If the butt guide is too springy, it will bounce the butt of the pin off of it, and down vertically past the pinholders. I say, the stiffer the better.
A couple companies make 1-piece urethane pin butt guides - those puppies do not flex and I do not have pileups or tablejams where they are installed.

2. Some folks like the idea of removing the top two rollers on the #1 tracks, and/or even drilling a new hole in the stringer and lowering the top end of the tracks. Idea being that you want the pin to slide into the bin as horizontally as possible - thus lessening the chance of it standing up.

3. Sticky/worn/loose pin holders or bent/loose shuttle tubes.

Good luck.

Shuttle could be too far forward too. Check the gap at the back, I see this from time to time.

Make sure that the distributor is extended all the way out. If it is to short the the pin goes into the #1 spot will rock and the butt will go down first. I had the same problem on one lane.

Make sure that the #1 shute roller guides are parallel to each other. If the bottom ends are wider than the upper ends, the head pin will tend to stand up as it goes into the bin.

Had this fault before! Your dizzy belt is to short. Dizzy carriage is not extending all the way at the one pin due to your belt being cut to short.
