Good video now i am a Woodworker with over 20 years of professionals working in the Architectual Woodworking industry and metal is something i want to learn more about the one thing i wanted to really stress was why no safety glasses I worked most of my career on commercial jobsites and i have had freinds have metal shavings and splinters Stick into their eyeballs and i know it was very painful and the way the Emergency room had to remove them was having a doctor use some very high quality and pointy. Tweezers picking one peice out at a time ! Ive scratched my cornea by having. High winds. Blowing. Sand into my eyes not that uncommon as i grew up in Florida and was riding a motorcycle with sunglasses instead of goggles
Yeah, this style of press break is not great for making boxes. It is not about the size of the machine necassiarly. If you take off the top support (I know it is very heavy and on adjustments screws), and clamp flat bar with long throw and depth C clamps, you can do it.
You mentioned at 5:30 to use notcher instead of band saw. What do you mean by notcher? (I know about shears, scissors, slitting sheers and nibblers, but never heard about "notcher", at least not for this task. I know of the notcher hand tool that is used to create small fingers [about 3cm deep and 3cm wide] on the edge of the sheat and for dovtails).
Edit: Wow. Only now I realised this is NYC CNC, and the video is 10 years old. :)
good video. Yeah he is not wearing shoes! so what! he isnt making a safety video anyway! He is also on carpet hello. that piece is very light and small. Its his choice to not wear shoes or safety equipment maybe not a good choice but Im not on here looking for safety tips I wanted to see that small metal break being used.
thanks so very much for taking time to make a great learning video, thanks to the polite experienced guys also posting like nirotix adding good pointers, nirotix wish you had time to make some teaching videos
There's gloves for working with sheet metal, any metal cut can get infected then you need a tetanus shot, I worked sheet for five years fellow worker lost his elbow from metal cut into the bone from a sharp edge
To the guy @NYC CNC who made this video...............Great intro for beginners like me........I had Wood, Metal & Machine in high school. I am 65 now, so that's quite along time ago
and I incorporate just about everything in building things today. I get information where ever I can. I remember you from a youtube video you made some years ago about building
a melamine overlay table and a fence for your Micro-Mark Multi-speed Mini Band Saw..https://www.youtube.com/watch?v=gwbhoQlUDPs I still own the same band saw myself
and wanted to make an equivalent of that same table, fence and miter guide but instead use 3/8th or 1/2" 6061 aluminum. However, the video
https://www.youtube.com/watch?v=gwbhoQlUDPs has something wrong with it and towards the end of your instructions, there is no longer any sound to it......crap! Wish I had all
of your instructive videos.
Thanks also to Nirotix for the commentary, it's all good for me......I have tons of projects
to save metal and make corrections draw your break lines on thin cardboard then cut it out with scissors and use a straight edge to fold on lines then if your box isn't right adjust with scissors then unfold box and use as pattern to draw around with fine point marker on to your sheet metal then cut it out and break on lines while you have the cardboard pattern folded into a box you can check the layout of what you are putting in the box this also keeps you from having a bunch of lines on your sheet metal to get confused about when you get to the break little metal boxes can be tricky so have fun
Hey an oldie but a goodie I found this one when I was looking for hints on sheet metal box design - need to make a box with a "tonguw" out front for my microwave spot welder not having mush luck - oh well!!! Good job as usual . This must ave been one of the first videos of yours?
Everyone needs to stop freaking out about bare feet. He is working with a tiny piece of metal. The only reason boots are important, for sheet metal work, is because you are working with big 40 pound sheets that could cut off a toe if dropped. That things like a couple pounds at the most. He is going to get a really painful scratch, in a worse case scenario.
Good video, and valid safety points. I do believe though there is enough stress in life that we could dispense with the gutter talk. You can make your points without being degrading. I've not seen NYC's later videos but I'm sure he's improved and could definitely show me a thing or two. Just remember to be nice to people and treat them the way you would like to be treated. You can encourage those with the wisdom you've been gifted with or learned. Thank you
One time I was installing a furnace and the homeowner was Asian and did not wear shoes and we told he there were sharp corner chips on the floor, oh by the way the electrical service was getting upgraded so for a short time we were working by flashlight's, and the owner comes over to see how thing are going and gets a sharp corner right between his toes the guy lets out a Asian WOW!! so yeah wear shoes..
DUDE!!!! this made me goosebumps... never use a saw like this, metal easy twist and you dont want to buy yourself a half hand, this will cost you really money than.
I guess you not worked much with metal in your life...good luck and be carefull mate.
the idea is good. nice video
+Tommy Arnold it is just a small cheap band saw. It is a MicroMark Deluxe Band Saw that sells for about 3 to 4 hundred dollars. It is about the same as most any other cheap band saw but it has a slower blade speed for use with thin metals like for hobby. Do your research depending on your desired use and expectations.
Another freedumb loving sheep. Maybe someday they'll have a dept you can call and report him and they'll attack his shop with a drone for "illegal activities" and raid the place. Typical. Go watch Faux Newz.
Not sure what metal you used for the box, but if it's Aluminum 22 Gauge it's far easier and probably more accurate to scribe and fracture than to use a band-saw. At least it is with relatively simple shapes. Think of it like cutting glass where you create a tiny weakness with a scriber and then just fracture it. See http://bobhooversblog.blogspot.com/2009/03/cutting-aluminum.html - An interesting site and full of good tips.
Always wear gloves with sheet metal. The one time I didn’t, recently, I badly cut a finger. And I’ve been doing this for over 50 years. Don’t ever think that it’s a small piece, or it’s aluminum or brass, etc. that’s when accidents happen.
I am wondering why your not wearing protective eye wear? This I feel is very important due to the fact that metal clipping can fly into your eyes. Please take note of this. If your trying to teach someone start with safety first.
Great tutorial what would work great to keep your material from slipping when scribing would be that rubber material you can buy in rolls for lining shelf's.
Your metal would not budge a centimeter on that stuff.
Tx for sharing, i love to get tutorials as much i need for home, i hate indonesian metal worker, no one can be trusted, once i know how to DIY, i can design & make myself, i used to help mom to make cake boxing since kid i watched what she could. My grandpa didn't love women, so i changed his mind, that i can be like man do as well, sometimes i helped my grandpa to do what he wants, fix his gas fire gun for his stove. He realized, i was smart, i didn't learn from anywhere. I'm happy to find this tutorial, i'd like to open culinary business to help disability, since i hate workers who are disability betrayed us as chinese, primitive sellers/metal worker liked to rip off my money. And i won't ever give my design to them, they love to duplicate, i have uncle who's expert in design of furniture, & i suggest him to produce metal furniture to beat the wood furniture who make profit like killer, but quality is very low, bug's eggs breed stays on our wood's furniture. I hate uncles who love woods, so i'll wash their brain to safe money to use aluminum metal.
I had been thinking for years, has planned to do my mission, but i need doing homemade projects as well, i've so much hate to Indonesian Government who give tax so high for imported fryer electric from china, also kitchen utensils.
I'll make box for my bicycles to prevent wet from raining, & also primitive love to steal. I have a heater for boil water, that special to be put on aluminum glass, i'll use it to make CH fryers from aluminum box. I've looked on expo, no one fryer i liked, too small, too large as well, not worth it to buy expensive, I need to build a portable Teppanyaki griller combined with fireproof glass, i can't find size i want.
hey 'Nate J' i just realized the post is a few months old but im a certified auto tech. But going on a whille now all i do is custom jobs fabrication, Installing air ride on alot of mni trucks always cuttting/pressing/welding alot of metal along w/ stainless. If you are stil interested in rectangular S.steel box send me a message. I LIKE YOUR STUFF NYC CNC!! it looks like you went a looong way from being practicly nothing in a apartment. Thats awesome i can only hope that one day my business im trying to start turns for that direction. good stuff
Nice little home shop. Respect.
As a Journeyman Sheet Metal Worker that runs a shop (being just me), fabricating everything 5 crews need for Commercial and Industrial aside from generic crap I'll give you some pointers.
1. Get a slide scribe if you want to scribe sheet metal. I used to be a machinist, calipers are NOT what you want to be using.
2. Allow for bend allowance if you want to be so accurate. I can see your box & pan has adjustments for that, most don't.
3. Buy a pair of red and green Wiss Snips, 22g sheet metal is nothing to cut through accurately. I chop through 16g with snips if need be. Best investment for a tool cutting heavier sheet metal, a Unisheer.
4. If you are making a box, hem your leading edges with a 1/2 inch hem for strength being sure NOT TO crush your fold, but just after leaving a tiny bubble. Secondly, leave 1/2" to 3/4" tab's on all your folds that you can 'slip' underneath the 1/2" hem when folded holding it together and giving it strength.
5. You are right, that Box & Pan can only handle about 1-3/4" 90's.. however.. a sturdy table with a sharp steel corner and wooden mallot are mandatory for any sheet metal worker. NEVER use a steel hammer against steel with steel as a backing unless you want to stretch your piece. You can use steel as a backing to hammer against with your piece, but only use a wooden mallot to hammer with.
6. Stop buying over priced steel from Home Depot. Go to a local Sheet Metal Fabrication Shop and buy 1 - 3x8 or 4x8 sheet of metal of every gauge you want to work with.. 26g, 24g, 22g. The cost of a galvanized sheet of 24g sheet metal 3x8 is about $14. Ask them to roll it up and put a tie on it. If they are trying to sell you it for $50, tell them to go fuck themselves because you know the cost of sheet metal.
You are welcome
Hey Nirotix - WISS sucks ass - everybody reading this should buy some Midwest or Klein snips - also, don't disregard the power of OFFSET snips - learn how to use em, noobs, they'll change your life....
if you are using 2mm sheet adjust the bend location out by 1mm on each side. this will allow the inside corners to meet up but will also allow your current bend sheet to fit inside the sides, especially helpful on the last bend and will also give you a nice groove to weld in.
Tig is great for welding ali, just check you the thousands of videos and you will see the results you get with tig.
Had it for about a year an haven't completed anything yet other than a 304 plate that holds my E-off switch and switch for my smoothstepper. I just keep running into different problems, but It's coming along. I'm working on a set of gaming dice for a friend which are 4, 6, 8, 10, 12, and 20 sided. Each requires a set of jaws to be made, and most of it is 4th axis work. Thanks again for taking the time to do what you do. I've tried makings couple videos, an it adds so much time I eventually stop.
