Re: Custom Stainless Computer Case (Help)

The problem is where the door hits the case it's completely flush and if I place it there it will stick up a bit. You know there are a "flared" version of them? They are easy to recess. You just need to drill and counter-sink a hole and just press down a screw. If you can't use a press or...

Re: Custom Stainless Computer Case (Help)

Have you ever tried "rivet nuts"? They work exceptionally well on sheet material. You can get them in small metric or SAE sizes and then choose a fastener head type (like stainless button head torx) that suits your fancy. Yea they are awesome. I actually have one of the tools at home that...

Re: Custom Stainless Computer Case (Help)

Airflow test and fitting are finished all that's left is to clean up and set up some kind of latch instead of screwing into the case.

Re: Custom Stainless Computer Case (Help)

Well at least your welds are looking lovely :) I hope it works out for you. If not, switch to aluminum; its a better material for what you're after. Something else you do possibly do is to drill/punch holes in the side panels to increase the venting especially since you have a motorized fan in ther...

Re: Custom Stainless Computer Case (Help)

I was so wrapped up in reading your thread, I never stopped to think about what you were making exactly. I am dubious that choosing stainless was a good idea for your case. Stainless has pretty bad thermal properties in terms of dispersing its heat. So all the heat generated internally by your comp...

Re: Custom Stainless Computer Case (Help)

First fit up. The welds just look brown from a far so they will be brushed and then I hope to get a nice reflective finish after this.... Pretty ugly for people who don't like welding. :lol:

Re: Custom Stainless Computer Case (Help)

I started welding it today and well one of the pieces is 1/16" off so I can't do an autogenous weld on one end. I had to bridge the two sides and add some filler where it was off but that put a lot of heat in and lost the color for 2". Btw I am welding in the flat. It does not look great f...

Re: Custom Stainless Computer Case (Help)

The piece I will be welding is going to have a continuous weld that will be 19" vertically. Obviously I plan to tac a lot but I was wondering if I should alternate my welds on each side until they meet in the center? So I would weld say 3" on the top and then 3" on the bottom right aw...

Re: Custom Stainless Computer Case (Help)

Here are the test pieces I have the the one farthest to the right is just me controlling the foot pedal on an aluminium chill block the middle is the same thing but with gas dams and the furthest one is everything but with pulse ( not set right). Thank you for all the help!

Re: Custom Stainless Computer Case (Help)

Thank you for the info I think I found my key setup. First I added a makeshift gas dam that makes a valley where I can contain the gas. I haven't been able to fine tune the pulse function to my pace so for now I will just stick to flexing the pedal. That gave me much more heat control and a better l...

Custom Stainless Computer Case (Help)

I am setting up a custom computer case for myself and I wanted to do something special. I am using 16 gauge stainless 304 as the two side panels and the front. The welds were going to be part of the artwork on the case however I have run into a bit of an issue. I made a few test pieces to weld so I ...

I am having a hard time walking the cup.

This is my first time practicing walking the cup and I am having a bit of an issue with using my gas lens with number 6 cup. When trying to move along joint I am using the upper "fat" part of the cup to pivot on, however the lower skinny part of the cup sometimes comes into play and messes...

Re: I need constructive criticism of my welds.

Looks like you might be long arcing your starts on the open butt plate and have a bit of inconsistent travel speed on the same. Try clamping your stinger a few inches lower on the rod or find a more comfortable position. I don't see any undercut or porosity. Looks good. Maybe add a little more meta...

I need constructive criticism of my welds.

Hello, I am new here and have been welding for a few years and all of my education was from videos online and trials/failures. Most of my welding was Mig and Tig, but I have been having a lot of fun with stick welding. I currently have an Everlast Powertig 200dv that I am using on 110V. I have kind ...

Greetings from West Chester Pa

Hello I am a newer welder and want to take things to the next step. I have been tinkering in my garage for a few years and even-though I have a fellow welder in the family I wanted some more and or (alternative) information and tips. :lol:
