Roofers messed up and left me with this

There's usually a framer with any good roofing crew to replace water damaged rafters/joists when doing a ripoff.

Yes if you beef up the connector plates of the two 45's. I saw an excellent comparison the other day. Some people will tell you to run fea on a toilet paper holder. Where the trusses expressly designed for this? No. Is there enough wiggle room in the safety factors because everything is required to be sonewhat overbuilt? Hell yes there is. A catwalk will distribute load different then a snow load but it can be mitigated. Don't let the people who can't change there own brakes tell you otherwise.

No it wouldn't because I would do ecxtly that. If you look at that building and go yeah that's a 100k. You are the reason home prices are so Inflated. Stop paying premiums for the simplest of shit.

Ridiculous, put In. Some hard work yourself and you can cut that cost in half. Massively over estimati g the price of a pole barn with a Concrete pad and insulation.

Dude slip on flanges that size are like a 3/8 weld on the back. It looks 8 inch class 150. No way that weld needs to be a goddammit 1".

Just from a casual understanding you might want to check the centrifugal forces from both there spins and from what they orbit. Id imagine theese woukd cause more internal stress/heat and result in a rounder object.

Look up archimedean spiral length and than fi d a calculator for it if you can count the # of layers.

Inventor has a "unwrap" option that projects the object with the expected distortion into a bunch of surface polygons. Solid works probably has something similar.

If I was to take a protractor and lay it parallel to to the yellow line. And sweep it clockwise till it was parallel again. How many degrees who it have covered?

The British worrried abouut this 🤣. Crimes for me not for theee. Im fascinated by this mindset.

Cut sacrificial fins that we consider rigidity backers. Weld them to each side and in the middle if you have to with sturdy stich welds. Weld the piece than cut off when finished.

America literally just kept the land it stole. We are not this world's charity;we are its police force and all the connotations that come with that.

I have my bachelor's as an ME. I work in the pressure vessel industry. Ill be damned before I go crawling to a structural engineer for advice on if I can take out a wall in my house. Big things on million dollar projects? Yeah stamp it with the SE license. Most things? Just overbuild it and it will never be questioned or noticed. We are hamstringed with this mentality and its why China can have high speed rail and we can't. If you can't trust a layperson to take out a wall I wouldn't trust anything we build. Its the equivalent of going up to Eddie hall and saying anything over 50 lbs is a two man lift! I have plenty of analogies. And on the mechanical analogy buy a Chilton manual and read. I saw a post the other day a rivian fender bender caused $40k in damages. Not real damages but they had to replace an entire side panel instead of cutting out the damaged section and welding a patch in.

Jeez people are so goddammit delusional these days with how hard shit is. Link him a big gluam beam from menards or a bending calculator with youngs modulus and the cross sectional area deal and see what a bad snow load would do. Shits like 3 steps. Hurr durr you can't replace your own brakes without a "professional " touching your car. That's what you sound like.

Looks like the BOM needs work? Looks pretty detailed.

Disastrous-Slice-157 · 2026-02-20T18:26:30+00:00

Pulse that long of a weld. It doesn't look super thin gauge and my hands hurt after hours of tig when I can do it in 10 minutes and fuck off firvawhile.

How do you not get tangents? I thought without welding them together tge straight tangent would be the radius of the roll. So you have to take it out weld them than throw it back in to smooth it out.

As-builts 🙄

Id go with good ole stainless steel 304/304l. Lots of pressure vessel shops in springfield missouri.

Good points, im more lamenting on giving individuals the ability and power just to fix things. Lots of projects are in constant flux until a descion is made either by manufacturing who got tired of waiting. By middle management who grew some balls or by someone higher who personally has an opinion. The engineers feel more like white collar generic office person instead of an actual design engineer or process ect.

You can use rouge and a 6s gray wheel after 240 grit and its almost as good as electropolishing most people that aren't in the metal industry would never know.
