Video title: How to Roll a Cone - Midland Fabrication
In this video students James & Luke talk us through how to roll a cone in a set of pinch plate rolls. The cone is stage 1 of constructing a pot belly wood heater.
The unit of competence that this is aligned to is MEM05010C Perform Fabrication Forming & Bending. The students are nearing the end of their trade training at TAFE. They are completing a certificate III in Engineering Fabrication.

If you're in the United States and watching a welding/fab video, it is automatically 20% more informative if the people in it have Australian accents.

Tremendous little machine! I have an old Pexto 36” in my shop (manual) and I love it. So many possibilities. Can you share the geometry method you use on cone rolling? Thank you for posting!

Nice and flat it lays! learned a lot! we need to make giant coolie shades. thank you. (sounds like there may be a helium leak in the plant?)

How can I know the last thickness of the hanger plate on the machine. Thank you cordially

Are you alternating raising each side of the roller or are you raiding the rollers evenly?

@midlandfabrication530 Жыл бұрын

This set of rolls, raises evenly via 1 handle

Always raise the evenly.

Thanks for the idea for a snubber. I am in usa and have never heard it called a snubber although I have never heard it called anything for that matter. I may try to make one. Is it held in by just that bar in front? Also why so many passes, is the roller just weak? Normally I would roll that in between 2 to maybe 4 or 5 passes. We normally start out getting it pretty close to done in the first time around then just fine tune it maybe a few more times through the roller. Cool video though. Thanks.

Snubber heald in by front bar and the rolling process pushes the snubber into the rolls. You are corect dont need to rotate so many times.
