Bar puller suggestions

Perfect.

What is the range on that puller? I didn't seem to turn it up on a quick browse.

I like this option. What sizes are you pulling with it? These would be 1-3/8" steel, 4 ft long. Roughly 20lbs max weight

I'll have to check for the actual range, but we pull everything from 0.125" through 2.063" with it.

I know the Royal is expensive, but you won't regret buying it.

Ditto, worth the money. Been using the Royals since 1989. We have six in service pulling 3/8 to 2-1/2. Saves a tool station, and because it's right there it's probably faster than a bar puller. Just be sure to rapid .100 away to clear the partoff teat before grabbing the bar. With faster machines you can't repeatably pull a heavy bar with rapid (and/or you may break the fingers) so we have rewritten pull moves in IPM.

What happens if the Royal style grabs a bar end and the machine continues on?
We are careful about cycle counts and bar lengths. Another danger is having too little stock left in the collet to hold securely on the last part, so we err on the side of wasting a short length of material. With the one shown we have had the bar slip and not pull full length if the bar drags in the collet due to oversize or dirt. We also found that if the operator closes the 3J collet with no material in it, it springs the collet closed slightly and causes drag when open. Fixed that by spreading it back open slightly, it hasn't broken yet.

Yup, always know how exactly many parts per bar, and set the loop count to match—with a drop long enough to be gripped by the entire length of the chuck jaws (or collet pads). Misalignment is addressed with a spindle liner; Trusty-Cook will make them with only .010 clearance if you need it.

I've found that years down the road the price is forgotten. All that's in your mind is the cheap POS you're stuck with or the great tool you wouldn't want to be without.

I 100% agree with you. I'm small, I'm bootstrapping this thing, and a $1200 puller ain't in the cards today.
