| this is what happens with my 20 lockformer pittsburg machine, first the problem is not as noticable on a long unnotched section except for on first and last 2 or 3 inches, but when theres a notch in the lock it looks like hell. i have tried everything and nothing chanes it. this is a sheared stock not hand cut. my small morlin pitts doesnt do this |

| What does the other side look like? Where is the extra width being taken from...is the inside of the lock still retain the same measurement - or do you loose some width in the fitting? |

| I have this problem with 24 Ga. Stainless steel. My hammer over edge will run even up until it hits the last notch or about 5in. from the end. Is your discrepiancy at the start or finish. I tore my machine down last week to try and cure this but had no luck. I think the notch some how lets the rollers suck in a bit more stock as the notch passes by because there is not enough material in the rollers to hold the work straight... but I truely do not know why, Also It is is always for me anyway the final notch. The wrinkles you have to the right of the notch may mean your roller pressure is too tight. I'm an idiot with this stuff so....also I cut very skinny notches that seems to help. |

Drizz,
Is your opening roll in good shape? Does it still have the spring on top of it?
Does the material pull itself away from the entrance gauge while running it through?
Is this a 20 GA Lockformer? What gauge of material are you running?
It looks like you may need to tighten the holddown bolts about 1/4 to 1/2 a turn. The material is not being held tight enough during the forming process and is wandering.
The material can be wavy from being too loose or too tight. You just have to find the right amount of downforce.
Chad. |

| yes its a 20 ga pitts one side ,pipe lock on the other, opening wheel is in good shape,no spring on it though, im running 26 ga galvy, i have treid the hold down bolts and it makes no differance tight or loose. i am baffeled and out good money on this machine, i wonder if the guy i bought it from knew. i have adjusted it so it takes metal in nice and even lock one end to the other when there is no notch. |
