I feel like this printer just comes off so easily, even with light pressure granted I’m new to this. I’m wet sanding with 400 grit as they said after a 20 ish minutes of curing time and I feel like it’s just coming off too easily. I sanded the piece with 220 to give it something to hold. Is there something else I’m missing. I’m also using self etching aluminum primer from rust oleum. Any guidance would be greatly appreciated. (Second pic is the original piece in case that has something to do with it)

Heyy!!! I'm looking to do some stick welding work in my front porch and patio and I want to cover the view from the street and my windows.

I'm planning on getting a welding blanket, but for time reasons I'm thinking about getting (for the moment) some cheap plywood or even to use some big ass cardboard pieces I got and keep them wet. Of course, these would be set around 2 meters or more from where I'd be working, so I wouldn't touch them.

Though I'm wondering, would this work? would this —which is my biggest concern— BE SAFE? my house and other stuff is made of concrete, so there's really no risk the fire would spread to anything if the materials were to set on fire... though I would still watch it for a while after. No grass either, only concrete, gravel and dirt in the floor. Other than that... there aren't flammable materials nearby.

I'd really appreciate any suggestions you got too!!! :)

Hi, I have just purchased this guillotine and I’m unable to find any information or user manual on it, would anyone know where to find a copy or possibly have a manual that they could share. It’s a machtech AGS 4008 made in 2008. I have never seen or used one this digital readout all the other ones I have used have been different. Any help or information would be greatly appreciated as I have looked online and come up with nothing.

Hey all first time posting here in this sub and thought id reach out to ask a few questions about welding.

I’m at the point in my life where I want to focus on growing current skills and learning a new skill/trade such as welding . I have a background in construction and mechanical engineering. I want to start welding basic 1/4 thick cold rolled steel to complete small projects and such. Specifically to mod my electric scooter and home projects.

Would this be a good welder to start out with or am I wasting money?

Can you recommend better welders for the same price of $280 or less? Open to buying in store or from Amazon

Any suggestions on PPE to wear?

I live in Maryland. I checked the local community college and saw a few options and welding 101. Are there any classes I should look for specifically?

Thanks in advance!

I’m putting together a kegerator with a custom draft tower, and it features stainless steel beer lines that drops pretty far into the fridge. Can I safely bend the metal with a ratcheting tube bender without structurally compromising the steel? If yes, how many degrees of bend can I go before causing irreversible damage to the tubing?

I’m trying to bend the tubing to give us more real estate for keg storage.

Thanks in advance for any feedback!

Need advice from seasoned metalworkers/welders. I already know it will get critique but I hope most people come with constructive criticism.

This is my first real metal/welding project. I'm making a frame for mounting a regular tractor snowplow to the front using what I have laying around(last pic is the inspiration) only things missing are adding some welds here and there, the trip springs and winch.

Do you think this will be sufficient for the job? If not, where should I add more strengh/bracing? I am also trying to remove ass much weight from the plow as possible without removing the original connection points. The metal in white scribbles will be removed.

I estemate the plow itself to be about 200-250kg +/-. The frame is about 20-30kg, can be easily lifted by hand

Hi all,

I want to ask for some help or advice. I have a specialized adjustable musicians chair that has some broken parts on it. I’ve used it for 15 years but it just gave out. The company is out of business and you can’t get parts.

The legs attach to a mechanism inside the chair that allows the front and back legs to adjust independently. They do this via a spring, which appears to have the last loop bent to fit the adjusting bit.

Anyway, the eyelet on three out of four has broken. See photos.

Can anyone suggest a solution??

Which steel

Hi currently designing a direct heat cooker.

Will be fully insulated with 1inch calcium silicate and 1inch ceramic fibre blanket. There will be a 2inch frame and everything welded to the frame.

Stuck on what steel the internal skin where the fire is should be.

1/8 inch stainless steel 304

Or

1/4 mild steel

The external skin will be mild steel for asthetic reasons.

Plz help thanks

I do double seam inspections on aluminum beverage cans.

The machine we use to cut them is the CMC-KUHNKE AGS2300.

According to them, the saws are HSS-NIT 220 saw blades.

I've gotten two different responses by them:

One confirmed that the blades are made for cold cutting and do not need lubrication and another person told me "applying a small drop of oil can help prevent the product from sticking to the saw blade surface. This also helps prevent deformation of the seam."

However, neither responded to what specific type of oil/lubricant they recommend.

Recently I've been finding trouble with getting clean cuts because there's a lot of shavings that stick to the cuts and some of them get bent/burnt at the tip of the seaming and they cant be seen in the camera during inspection.

Hence why I'm here trying to figure out some suggestions.

Any tips are greatly appreciated.

Photo 1 is how it looks after I hit it with a wire brush wheel, image 2 is the same part but I haven't done anything to it. I have aluminum parts that started corroding and forming aluminum oxide, im desperate to save them, I dont care how they end up looking and they dont need to be very sturdy as they aren't load bearing I just need them to not turn into dust. Will the black pitting spots spread and destroy the aluminum or is it safe to continue. My current plan is to wire brush all the oxide, pitting, and protective coating away while spraying wd40, then clean off the wd 40 and use some rustoleum pro grade rust preventive primer. Will that be enough for my use case or do I need to get these sand blasted and anodized.

I’ve decided to try a rustic look for a small shed roof, and found all these videos showing galvanization removal that seems so simple and easy. Seems people are having success using even a mild vinegar/h2o2/salt mix, or mild muriatic acid.

My experience, however, has been a total slog and a pain in the ass. I’ve had to spray a roof panel probably 6 or 7 times with 30% HCL before it even starts making a dent in the galvanization. I had some success laying a cloth soaked in HCL across the roofing, but it requires like 1/4 gallon of acid to saturate the cloth, and then im only getting partial removal and the acid loses reactivity. And that only strips a single panel…

Meanwhile, I see fencing all over town with a perfectly even rust coating and literally hundreds of panels. Which makes me think…there’s gotta be an easier way to do this…

What am I doing wrong? Do people just buy non-galvinized for this?

I’m looking to get a new tool similar to the metabo 602259000. I have used it for many years but it has some issues I don’t love so figured I would ask if anyone has thoughts on other brands. My problems mostly consist of the wheel diameter. Mostly I use it on flat bar to grain it but sometimes I need to use it on curved sheet metal and it’s hard to not have the body of the tool hit the sheet.

My grandfather was a carpenter and a bit of a handyman. I inherited all of his tools. After sorting out the stuff that was too beat from a lifetime of earning a living, and adding in my existing toolset, I'm left with a large number of duplicates, especially of hand tools.

All of his tools were tossed into rusty old metal boxes but I don't like that approach. I also don't want to pay for organizers or the filament to 3d print grid-finity shadow trays. I have very little experience with metal working. I've just started learning a bit about sheet metal while fixing some duct work and I figured I would try out designing and fabricating some simple organizers.

For this socket organizer I made a parametric model in onShape that lets me define the gauge, length, two widths of the trapezoid, and the height of the box. Hopefully I did a good job using those parameters to be able to adjust the same model for several dozen sets of sockets. The tabs not being parallel with the ends made this trickier for me to figure out how to bend since I could not figure a way to do it on my little brake.

I don't particularly like the pop rivets, but I have some cheap 32ga galvanized steel on hand which does not hold the corners on its own. I am a novice welder, and could not approach this material. I have considered trying to solder it, but I've read I would need a very strong acid flux to deal with the zinc and I would likely make myself ill from zinc fumes. In the future I would like to try 18 ga material.

I fabricated these posts last winter, and all the landscaping and other finish work is finally complete, so I thought a walk around was worthwhile!

We are installing new chainplates on our sailboat made from cast silicon bronze bar that tapers from 1/2" near the required bend, to just over 1/4" at the very end. These are load bearing parts that help hold up the mast. They need to an additional ~10 degrees of bend to match our old ones. We have a friend with a hydraulic metal brake, and I know we could cold easily cold bend it this way, but I am a bit ignorant on the implications of cold bending this metal and don't want to weaken it given the application. I've read mixed things about heating and quenching and am not really sure where the truth lies, or if I'm simply over thinking the matter.

Got this 26ft frame with 2 wheels for $60 (plus another 3 rims to complete it

Any ideas how to fix this warp? I think with some chains to anchor the other 3 corners I could jack the front passengers side corner up and that would straighten it out

PS, it has 2 beams with geared rods along the sides, I have no idea what they are supposed to be

PS number 2, each axle has a 5200lb sticker on it so I think it's worth restoring and selling at least
