25 years in sheetmetal, great videos, and instruction. I’ll be sending this to the new guy in the shop. He’s young, and wants to learn. I’m still learning too, thank you.
Super helpful video. I have my seams test for my basic tomorrow, and seeing the actual locks and seams on ductwork instead of in a powerpoint has been very nice!
Excellent video showing the various metal forming locks. No other video like it. You casually ran an acme lock on a lock former and that is indeed the volume production way, but I'd love to know the bead former roller sequence that the lockformer uses. I bought stainless stovepipe from an elderly Mennonite who had no lock former or even power to his shop: just a bead former. 28 seasons and he is gone but his pipes live on.
I a coppersmith hobbyist and try to do most of the seams by hand, would appreciate a close up of the bends after they are formed. nonetheless, this is a fantastic video and it's already bookmarked for future reference. keep it up.
Thanks for the video. You have a nice Power Point, can you share it. I teach a CAD class and wanted to include some sheet metal information my my students ...
What kind of machine was that you used for the Pittsburgh seam? Most of these seams appear to be used for HVAC, but I’m looking for a way to put that seam on metal for vintage camper restoration, thanks. I know you can make it on a brake. I have 2 siding brakes, but thinking you need the sheet metal shop brake like you have which are big, heavy, and probably expensive? Thanks
Do you have a a link to the presentation you're showing in the video? I'd like to review it more as I need to create a seam for a 1900's motorcycle tank and I think it's the ACME seam you show, however I'd like to review all of them. Really interesting video, more close ups please.
I’m not quite sure about your question but here is the link to my seams Locks and Edges video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Eaqj27qiky8.html
Pretty good question. I’m hoping someone else can jump in and help you out with your question……..I personally never made one but I am also the type of person that believes most things are possible. I truly only have limited experience with acme Locks and the ones that I have, we’re done on a roll forming machine………. I would start by sketching out the side profile of an acme lock, perhaps one may be able to accomplish something very similar as this on a brake? The material allowance for the lock alone will be way more than on the role of former. Everything I just said may not be practical for small gutter work, I would personally go with a groove seem instead. Sorry I couldn’t answer with a definite yes or no 👍
Thanks for this. I bought a 24’’ box break and made a Pittsburg lock from your steps and was perfect. Can you tell me why duct flanges are slanted notched. Is it for clearance for cleats?
Hi Johnny, if I understand correctly, you are asking me about the duct connectors. Most of my video demos have S and Drive cleat connectors, we typically notch them at a slant to facilitate assembly. I hope this answers your question, and if not, do not hesitate to ask again 👍
What textbook are you referencing here? Also what a fantastic video man. I'm an HVAC apprentice trying to teach myself sheet metal and this channel is a fantastic resource.
@@sheetmetalwork Danny Snow had his number retired from Oromocto High School I think. He is 60 now or so, so he graduated around 78 or so. I played with him in Maryland. I know Crosby well, we are huge Penguin fans and season ticket holders
@@UddstromNorm No i did not know Snow but sure know where Oromocto is. I too played hockey for many years, I’m 55 now, I was born in Gardner Massachusetts, moved to Canada when I was 10. I’ve always been a huge Bruins fan.
Hi Andrew, believe me I wish there was one and only book of locks and seams. These are taken from a 3 or 4 different textbooks and other resource manuals that we’ve collected through the years.
