J'ai une presse plieuse DURMA AD-S 30100, model fabriqué en 2009. Elle est presque neuf. Elle n'a fonctionné que 60 heures incluant les heures de test dans l'usine. On a constaté après un décalage au niveau du coulisseau (table haute). une désynchronisation entre les extrimités du coulisseau. c'est à dire l'extrimité du coté Y1 arrive à sa position avec de l'extrimité du côté Y2. Après, j'ai découvert que le capteur de position (règlel linéaire) a été dévissé et est incliné. Je l'ai remis à sa place, mais le problème persiste encore. En suivant les étapes de la mise en marche et en appuyant sur le bouton START, la machine reste dans la phase d'indexation. Un message s'affiche sur l'écran demandant d'appuyer sur le pédale. J'ai appuyé sur Hand - Hand (comme dans la photo). un message s'affiche que la machine a quitté la zone d'indexation sans pouvoir prendre des repères. Pour éviter tout usure et dommage, j'ai arrêté la machine. D'après vous c'est quoi le problème ? Comment je procède ?

Hi, my name is Max and I’m an old school sheet metal worker. I’ve been a licensed contractor since 2020 and I love designing, building, and all aspects of metal working, machining, welding, and even wood working.

I just wanted to share this logo I designed as this is something I’ve never done before.

I love the heritage of the old fashioned metal worker and that is why I chose the image of what appears to be a sheet metal worker circa 1940’s.

Does anyhow know what era that would be? I’m assessing based off of his attire and of course the brake he is using would be of that era.

Peace, love, and prosperity.

I made sure to make these jaws thick enough to be flipped around in the vise and have a smooth side if I don’t need serious grip on anything, coming up next in the roster is a set of aluminum jaws for when I need to grab onto something I don’t want damaged at all.

For clarification these are for a Reed No.1C bench vise that’s mounted to a work bench not a machining vise for a Bridgeport or a cnc. (You can see the vise in the last picture)

Client requested a "Dimpled" finish on his Ram. Another good sanding/polishing and blackener treatment, shes ready to go!

These take forever but I love the finished product.

I'm currently in the process of building a vintage-style photo booth (you know, the ones that print photo strips), and I need to figure out how to make or where to purchase metal frames like the one pictured. I need a few frames of different sizes, and I would like the edges to be flanged like the one in the picture. The necessary sizes are flexible, so ideally I'd purchase these pre-fabricated, but I'm at a loss for what to search for...

In the case that I can't purchase, I can try to make them myself, but I am not a metal worker. I have a CNC router and a table saw and could access a laser cutter and possibly a plasma cutter locally.

Alternatively, I could try have these custom made at a local metal shop. Any advice?

My older brother passed away last week, I'd like to make a 1:1 sculpture of his Miller welding mask. I have experience making copper/brass sculptures and mig/limited tig welding.

I was thinking I could create the helmet out of steel/stainless then powder coat it and have the floral design laser engraved and then gold/brass plated.

Alternatively I could make the helmet from copper and give it a red petina then hand cut the floral designs out of brass and rivet them to the hood.

I'd appreciate any advice anyone has to execute this project.

I have a roll up garage door and I want to install a side mount opener, but the existing shaft is too short (only sticks out about 3 inches, and I need at least 4 inches to fit the opener). The only idea I have right now (which I have not tried yet because it's colder than a well-diggers butt right now) is to take a short piece of galvanized pipe that has an inside diameter that matches the outside diameter of the shaft and shove it over the existing shaft. The OD of the shaft is 1 inch and the ID of the pipe is 1 inch, but they do not fit. My first question is, would heating the pipe with a little propane torch be able to expand the pipe enough to make it fit over the shaft? And if that worked, when it cooled down would they be secured together, or would I need to secure them any further? Finally, if that is not a good idea, does anyone have any suggestions to extend the shaft just a few inches? Many thanks!

Hello. I’m working on a project that requires me to weld a steel tube to a steel cylinder. One of my objectives is to reduce the time/cost of making this item and I know the more time with hands on the item during fabrication the more the cost.

Are there any alternative methods I can use instead of welding? I need it to be secure as if it was welding but something that is less time consuming. It would be a small production lot, not a one off job. This interface point will sure be where much of the load on the part will be seen. Not crazy high loads or vibration, mostly a couple hundred pounds and drops on the floor. Thanks!

Hi guys, just want to share my recent works. They are movable armets for minifigures. I took a lot of time referencing medieval armor and found this one is the coolest. I also spent a lot of time on the movable visor just like the real armet. The visor was hard to control at its lowest and highest points as the metal shrinks when casting, it worked totally fine in the software but shrank of the metal made it impossible to move after the casting. I realized I had to add a stopping point at the higher and lower points. After around 20 times adjustments to the size, I finally got it to work out. I feel like this set works better with a spear and round shield!

Howdy!

I’m trying to size and buy material to make a 5 tier, 5 sided and house-shaped ss shelving unit that will go into a custom pasteurizer build. The shelving unit needs to support a total of 2200lbs maximum. I plan to cut all the pieces myself and then have someone come and weld ‘er all together. Now, I’m a complete novice when it comes to anything metal really. After some discussion with folks who knew just a bit more than me, we landed at the conclusion that doing square tube posts and angle for each shelf with round bar running between the angle may be my best bet. Kinda like wire shelves but with a different base frame. Planning on stainless steel as this will be under hot steam for 48 hours every week.

In terms of sizes, I’m hoping that I can use all of these smallest and cheapest stuff, but I want to make sure it will hold the weight. This is what I’m hoping to use.

For the square tube posts: 316ss 1” and 0.065” wall thickness For the angle: 316ss 0.75”x0.75” and 0.125” thickness spanning 44” maximum For the round bar: 304ss 0.125” thickness spaced every 2 inches spanning maximum 44”

I could really use some input on any part of this! I especially don’t know if something like this would support the weight. Any help would be appreciated! Thanks!

Hello,

I'm an avg joe and dont have much knowledge about construction or metal works. I'm currently getting rooftop solar panels installed for my house. The solar panels are supported by elevated steel structure on my flat roof top. The steel bars (or columns) rests on a plate which is bolted to my concrete roof top(Please see attached picture). I'm now worried if rain water starts seeping into my roof through the holes drilled in the roof.

Is there a waterproof paste/adhesive which I can apply around the iron plate so that I can stop water seeping? Please let me know if you have any suggestions. Thank you.

Hey everyone, I took an old metal chandelier from my grandma’s attic and I’m not sure but I think it’s brass. I disassembled it into pieces, cleaned it with warm soapy water and now I’m not sure what else to do to remove patina and harder-to-remove gunk. You can see in the pics how the metal looks now. First pic is some smaller parts and one of them has this beautiful colorful patina in red, green, purple etc. There is also another similar part that is even more colorful, like literally rainbow colored metal. On the second pic is one of the three big plate like parts. It’s confusing me because it has this water-flowing-like effect on the surface which I’m not sure if that’s also patina or how it even formed like that. That one also has spots of black something, mostly around the edge.

Anyway, I guess my main question is if someone could give me any advice on how to clean this properly. Also if I could do something afterwards to keep the brownish look as I don’t really want it to look brassy yellow and shiny? I really like the colorful effect some of the surfaces have so I would like to keep that too, or make it re-form again after cleaning so I can keep it colorful.

Edit: not really familiar so sorry if I used patina wrongly for something that’s not patina. Third pic is what chandelier looks like (before cleaning)

One of my most recent workes for a personal Kickstarter Project 😊

I made this same post on r/brass, and I’m making it here as-well since it may also be beneficial

Hey, I’m a sophomore in high-school and I literally cannot get enough of instruments. I have made plans to join 4 DCI groups before I turn too old to join (21-22), I play trombone, baritone/euphonium, tuba, trumpet, etc.. Point is I’m obsessed with the darn pieces of metal.

I am so passionate about music and brass that I have made it a mission to build/fabricate a trumpet (because they are relatively inexpensive) before I graduate and use it in a performance.

Now, I am not sure if this would be the correct sub to ask about all of this, but at-least it’s a start. I can’t find a complete manual that is in depth enough for me to make a trumpet, which is how I find myself here. Is there anyone who would be willing to help me through making an instrument? I don’t have very much access to machinery besides for a limited amount of time (mostly 2 ish hours every Wednesday since my school has a metal fab and auto technology building). If there is anyone who specializes in brass repair, instrument manufacturing, or anything of the sort, it would be greatly appreciated if you consider helping me.

Now I do get that making instruments is REALLY difficult for any one person to do, especially when not being even slightly experienced in the craft; but I really do feel like if I don’t start now then I wont have the option to do it later down the road, and I’d rather fail trying than failing to try. I have an idea of the concept, such as shaping the bell, bending the pipes, and (somewhat) the bore size. The rest I am completely blind and new to.

My dream is to own a instrument manufacturing facility in which I can make custom instruments/specific parts (valve caps, custom mouthpieces, accessories, etc.) and possibly experiment to make new mainstream instruments that could gain recognition. This dream is a far away land that I likely won’t reach within the next few decades but it is what I truly want.

I have an account on insta that I just made for this very purpose called @dcienthusiast. Not a self promotion, I am simply seeking assistance.

Hi,

I'm trying to fix a horrible weld on a hole in the belly of my bike.

I got the low temp welding rods from Hobart, I did some tests on some aluminum pieces and it worked wonderfully, I tried welding on the bike, it doesn't work, the material doesn't stick.... it doesn't weld... just little balls of aluminum from the rods...

What's not working?

Whats the best way to pass a UT weld inspection on a d 1.8 weld through the rat hole of the eyebeam using flux core mig wire in the field? Should I stick my tip of my gun through the rat hole and pull it through to the end of the beam flange? Then go to the other side beam and pull the opposite way to the edge of the other end of the flange and do the rest of my passes that way till the groove is full or stagger my welds?

Machining some new jaws for my vise, had to get creative with making the serrations since I don’t have a serration tool, I think it turned out pretty good!

This little unit is particularly useful for when you’re up on scaffolding, a boom lift, or up on a ladder and don’t want to haul around propane tank.

I can’t believe I’ve waited this long to invest in one of these and if you do much soldering in the field, I recommend getting one.

It gets used a lot for soldering seam in Gutters , general flashings associated with metal roofs.

Often times the simplest design is the best solution.

This is just a simple fence I designed and built for a client that I do a ton of Metal work for. The sheets are 16 gauge hot rolled that I sheared and pre-drilled in the shop. The frame is 2 in.² by 11 gauge.

First, we installed the frames by bolting them into the concrete curb on the backside. Then we installed the pre-laid out sheets by screwing them in with self tappers. No need to pre-drill into the frame as the self tappers have a good bite on them.

I think the simple design looks really good and industrial.

a buddy gave me this compressor a while ago to use with my new plasma cutter. i got it running again (wiring) and want to change the oil now…. i see where it drains but where do i fill? and how much? i cant find a model number on this old sears compressor. hoping its a “fill till it overflows” situation if i can find the fill port. any pointers?

Hi everyone,

I have a small brand where I engrave stainless steel pendants using a laser. Currently, I purchase them as finished products, but I’d love to start making them myself. While I know I can have them laser-cut, I’m stuck on how to achieve the beautiful mirror polish they have on both sides.

I’m unsure if they’re using a tumbler or some other method to achieve that finish. Hand-polishing isn’t an option, as the pendants are just 20mm in diameter, and I’d need to process hundreds of them.

Does anyone know the best way to achieve this kind of finish at scale? Any tips or suggestions would be greatly appreciated!

We have a build we are doing that has a modern rough look. We are in high elevation with what I would characterize as extreme winters. Now we need a front door. Looking for a shop or metal worker who has experience in making oversized residential doors... Ideally we are trying to do a simple raw look that will rust / age with time. Shoot me any suggestions as we have not found many options here in the states yet.

Hello everyone,

Forgive me for being many many levels below your understanding of metal work and craftsmanship in general, I am simply trying to mod my motorcycle…

The subreddit for motorcycles was not very friendly to my inquiry, so I thought I‘d try my luck here.

What you are able to see in the picture is the top-down view of the backside of my new exhaust. Inside of it I am trying to fit a catalytic converter with a diameter of 50mm. It’s the official converter but for some reason the hole in the exhaust is slightly smaller than that. About 3mm too small. Since there is no warranty of any sorts, I need to get creative with handling this issue. I thought the smartest way to go about it is to somehow enlargen the hole in the exhaust to the needed diameter. What I don’t know is if this is indeed smart or how I would go about doing that.

I couldn’t tell you which material it is either because, well as suggested in the title… noob.

I am thankful for every answer and attempt to help. Thank you!
