I'm going to put a heavy bag on it.

Its a concrete anchor. It goes 2inches into the ceiling and holds up my skinny 70kg ass. A 30kg bag won't be a problem.

I'm going to agree with the other anon. You arent using something that is built for a hanging swinging weight. I would look into some 3/8" drop in anchors for better support. Its not so much that the nail wont hold, its more that the concrete probably wont. Concrete as you know usually isnt super consistent, and tends to blow out rather easily at the edges. Precast (what your ceiling is probably) tends to blow out with any sharp blow.

I have had to many issues with tapcons to suggest that style of anchor.

>> No.690845

good idea. last time I used them were the1/4" ones x 1-1/2" for drilling into 11" concrete ceiling and hanging spiral duct from them. Screws were rated for around a 200lb load. Only problem with multiple screws in concrete is spacing. You need at least 3-4 inches minimum between screws. Epoxy is good idea.

>> No.690854

not a tapcon.
The drill out is smaller than diameter of center of screw. It takes a real drill to drive them into the concrete. And other poster idea of epoxy makes them great.

Big metal buildings you see? They drill hole in slab, toss in epoxy in a tube, and then slam rods onto them breaking glass. And that is what holds those huge ass steel pillars and beams anchored in place.

The handles are all made with sisal rope which will lay flat enough to utilize the majority of the space.

The final dimensions are roughly 3' long by 2' wide by 22 inches high. I built most of it sans power tools (since I'm poor and don't have any besides a drill) I did use the drill for the rope holes since I couldn't find my bit and brace.

Has to be rather accurate to the character's one though. I did have the idea of using PVC piping but I want it to fit together cleanly, not to mention I wanna easily reproduce them.

>> No.695598

PVC pipe comes in endless (not really) shapes and sizes. More than likely, you'd be able to find pieces that will be exactly the right size for the different elements of the gun.

Also, PVC pipe is made to fit together. I'm not sure if there's been some sort of misunderstanding.

Hell you could even carve most of those pieces out of high density foam. Also, you can bend PVC by filling the pipe with hot sand and shaping it around a form. for that size a piece, its going to be a very wasteful print.

>Why are you testing airfoils
It's a safe assumption that anon means 'We're testing various body styles to determine what factors most significantly effect the drag coefficient."

Cool wind tunnel. Is the air at the point of the test object smooth or turbulent? I read a trick somewhere about using a wall of soda straws to smooth turbulent air, and wondered if it was really necessary.

>> No.697953


Then perhaps that anon should have used grossly incorrect terminology. Also, considering electric vehicles tend to be nothing but airfoils my point is extremely valid.

No fucking shit. Look at the picture. It's high school. The important skill to learn is thinking. I asked a leading question so he would think and Google it and try it out.

>> No.698381


If you haven't learned to learn from other peoples mistakes by high school then asking a vague question with positive regard for what they've already done isn't going to encourage them to look beyond what has already been done. It's going to make them think "other people think this is alright so it must be." That they hadn't looked up the important factors of a wind tunnel puts further doubt on how much "thinking" they have learned. In short, you're a fucking idiot to be vague when some one obviously doesn't know what they're doing and then getting pissy when some one points out their flaws so they can actually learn something without the thought of "wtf did that guy even mean"

Might as well just order the expansion bolts/drop in anchor/epoxy studs now. The steel might hold, but if you're going into concrete then that will fail first. Concrete is not like granite or other rock and will crack and fail quite easily, especially over multiple cycles of loading/unloading. I place bolts in all kinds of shit and concrete sucks (God help you if you hit a piece of rebar...) It takes four 5/8" bolts sunk >4" deep to make a decent anchor in concrete slab, but that's for fall protection. Double up on the bolts, and sink them deep.

Making my basement into a huge survivalist/fallout shelter.

Working on storage shelving every wall in my basement. No pics.. not that exciting. I am pretty proud of the fact that I have managed to spend only the cost of screws on the project (well, and wear and tear on tools I guess) up to this point. Using all dunnage lumber and scrap plywood from factory I work at. So far have about.. hmm well let me figure out exactly.. 576+120+24+124=844 square feet of shelving along walls at cost of a lot of probably 30-40 bucks worth of drywall/all purpose screws of various lengths. Shelving is split between standard storage bin size and roughly magazine shelving size. Have a bunch spaced to serve as bunks if need be.. currently can sleep 9 if bins removed (adults). Also ripped out the walls (just the sheathing part, not the structural part) along the side of my basement stairs and put double wide shelving there half of which is accessed from the stairs only and half from the basement side. The section that overlaps the portion where the stairs cover part of the shelving as they angle down is now a hidden storage area with false backing.
On the list of 'to dos': flip down steel plate basement window covers, Exterior concrete planters which will slide into the slots for existing basement windows. Finish air tightness sealing in a few places. (Using various kinds of greatstuff and also some waterproof coating stuff I think is mostly for bathroom remodels.) I need to figure out a way to add a media box to put filers into the chimney cleanout and add a squirrel cage type fan which can reverse the flow to suck filtered air down into the basement from the top of the chimney. Will try to get some pics once it looks more interesting than: "Heh, nice shelves."
