The bottom right corner of the mirror keeps bending off center and I’m now sure how to fix. Does anyone have any advice

hi there dear community - many thanks for running the awesome subreddit.

I am currently working on the frame buildingbfor bikes.

At the moment we re look for tubes and some suppliers. here i found a map - that might be helpful

note: https://utahrandonneur.wordpress.com/2022/02/28/map-of-italian-cycling-brands/ The map was created by Andrea Bonfanti from Italy. He a noted De Rosa historian who also wrote the book on De Rosa bicycle history. I have both the map and book, he does an amazing job of research and is very knowledgeable and approachable.

Are the punch and dies, brand specific or a standardized size? Like can you use them on different machines because they are standard sizing?

We can't afford an ironworker just yet...and honestly it's a bit overkill for what we do...but we will be buying one eventually. Our mill just broke and the part won't get here for atleast 3 weeks. My question is will this punch and die Edwards / Punch & Die Sets for Ironworkers - Edwards Ironworkers | Work More Iron for Less Coin work with one of these Amazon.com: Bonvoisin Electric Hydraulic Hole Puncher Φ1/4"-4/5" 1200W Punching Machine 110V Metal Hole Punch with Carbon Brush 5 Dies for Iron Copper Aluminum Plate Angle Steel : Tools & Home Improvement

Only punching 6mm aluminum plate. I am novice as they come with metalworking but have already passed aluminum welding certification. Any help will be appreciated and reciprocated.

Any under 1000 dollar machine/punch/die combos that you know of?

this is what happens when you put in the wrong tool . should of used a 3/8 end mill finish . instead i grabbed a 1/4 end mill .all that i damaged way the clamping nut on the tool holder. Part size 1.10"x .680"x .980"

Hi all, been trying to get a mirror finish on a brass project, have bought all the correct grit wet and dry, polishing bars and wheels.

Been through the full process of wet and dry right the way up to 5000 and even 100000 grit.

Using a polishing wheel on a grinder, felt type which was supplied to us with brown and blue bars. Just can’t get the end result.

Any help please

I know a few of my favorite pairings that work well, but has anyone found a guide that lists all the best fitments between the tube sizes and wall thicknesses? I've found a few for aluminum, and the same site also lists steel but the sizes are either converted from metric or fantasies.

Something like this for mild steel in imperial sizes.

I have a front gate i'd like to put up, and i am struggling to find the bracket/nut and bolt combo online. The picture is from a neighbours front gate, I have the same type.

Hi all! I'm an art student with little metalworking experience and I'm making a giant metal spider for my graduation project. Its a spider that people have to give a hug, meaning there will be weight pressing on it. Its so big that the legs have to be detachable to get it through the door. I thought I was smart and made the legs into 3 smaller pieces that can bend at the joints and I made those joints into hinges (photo) so they can be bent in the right position. However, I also thought that if I screwed on the wingnuts tight enough the hinge would be unmoving. Its not. Any advice? I don't want my spider to collapse during my exhibition after a couple of hugs 😅

Hello, i have 2 questions and i would be very thankful for any advice from someone who has experience with metal.

I am planning on making a full samurai armor set (modified to be a bit bulky and heavyweight), the question is.. what metal do i use? I already made templates from cardboard and have a plan but now i'm thinking about choosing a material. I need something relatively light and easy to cut and bend. Also the armor is made from many plates tied together so i guess something easy to drill through aswell.

The other question is, how thick should the metal plates be? It's gonna be more of an accurate replica to wear so i don't wanna make it ultra thick and heavy, but at the same time i don't want it to be like paper.

The lower the price the better of course.

So I'm working for an auto/fab shop and recently my employer wanted to figure out how to melt steel and other Metals to cast into, whatever we need at that moment, he however lacks time to look into that I suppose and I find that stuff neat, so I figured I'd go look for somthing small enough that can fit into a small fab shop (automobile stuff is in a different part of the building and isn't actually relevant) so like, a crucible forge made of graphite or, somthing along those lights that can be heated up with oxy-acetylene without, actually melting the crucible and the, thing that its held in, any suggestions would be lovely.

Angle grinder seems like it would be miserable, any ideas are appreciated!

Heya r/metalworking,

One of the equipment mainstays we use at work involves 1-1/4 pipe fittings with
3/8" weld on nuts.

As we manufacture more and more of our own custom pieces, one of the stumbling blocks we've run into are sourcing round, weld on nuts that match the specs of the standard fittings we already have. My bosses are sticklers for style as well as function, and they'd love to have solutions that looked slightly more sexy than the back alley chopshop "just weld on a nut and call it done" solutions we've come up with so far.

I've found a couple of things that are close, but I can't help but feel as though there are standardized search terms for these things that I haven't stumbled across yet.

I've found nothing that fits at Mcmaster-Carr under their weld on nuts.

On Amazon, I found Uxcell Round Weld Nuts and Notched Oxygen Sensor Weld on Bungs, which are both almost EXACTLY what I'm looking for except that one is only stainless and the other I can't get in 3/8".

Is there something else out there that I should be looking for, or should I just go to a machine shop and get them to make these for me in bulk?

What I'm looking for are steel, 3/8-16 receivers that are 5/8 wide on the round and a 1/2" tall. Both flat AND notched would be amazing, but beggars can't be choosers.

Sorry if this isn't the best spot to post this, but I know nothing about metalworking and just ordered a custom made nazgul helmet (inspired off of helm hammerhand's character from SoW for my fellow needs out there) from etsy and... well there is a slight problem with it, if you can spot it: the eyes are kinda blocked, and I need those to see.

Basically my question sums down to how do I remove the bit blocking the eye? Thanks for the help.

To Preface this post: I do not know welding very well, and I am trying to supply a team of oven techs with the tools they need and get the correct accessories.

So I work at a commercial bakery and we have a broken thermal oil tank. I have some techs coming out to fix it and they requested some supplies.

They need an oxyacetylene rig and a nitrogen tank for shielding inside the thermal oil tank.

The oxyacetylene rig I understand and I sourced the tanks, hoses, regulators and a cutting and welding head. But for the nitrogen tank, what do I need as far as hoses regulator, and a way for them to use the gas.

Thank you in advance
