How to Roll a Cone – Midland Fabrication

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.

I've worked in the industry on and off most of my life and the videos you guys make to help me remember simple stuff I forgot has been extremly beneficial. Thanks Guys.

Students with a bright future. Instructor allowing them to take initiative and lead the demo. Nice to see 👍🏼

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.

Love your work guys, kudos to your instructor also, and as students you're doing fantastic work as teachers

[henryblack]

Good on yah TAFE. THANKS GUYS from Sydney

[igolopez]

This technique really works. Thank you so much.

[juanmestradav]

Awesome job! Thanks for teaching the technique...

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!

[danielmiller]

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

[MUCKFOOT]

weld the seam, then run it through one more time to get rid of the flat spot.

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

[adammoore]

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.

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?)

[garrydixon]

How do you figure out the ring that you cut before rolling it.

01:30 I saw Turkish product machine "Akyapak"

[jonhyx]

Never seen any one move the snubber more than once
