/diy/ - Do It Yourself

i have an engineering degree and i have been watching lots of videos on how people build ramps and ive seen some atrocious shit... you know what else i have seen? those same terribly built ramps continue to stand.

IVe been putting up shittily built wood ramps for a few years now, and the designs keep getting sketchier and sketchier and they keep not falling apart :D

>>2466117
>I'm fairly sure this ramp >>2463064 (You) is at lower bob's and the guys who built that actually work in construction for a living so they know how to build forms that will support concrete adequately.
how do i get a crash course in building (ghetto) forms? how do i contact these guys to see if i can join any of their projects for the learning experience?

>>2466117
what are some of the key strength differences between wire mesh and rebar?

>>2463894
thnx, i learned today
-not op

is 1gal jug of ardex the same as 'latex additive'?
I was told i could also just use buckets of latex paint.

>"Beach and desert sand are too dirty, too full of impurities and even too rounded from constant tumbling in water or from wind to used for a quality concrete product."
considering i have shit home-made concrete, do you think i should use sac concrete for the edges and seams of the ramp, and home-made concrete for the majority of rest of the ramp? would it be worthwhile to add in 1part sack concrete for every 3parts of home-made concrete that i mix up?

I also have a lot of super fine 1/8in gravel... would it be good to mix up a batch of 3part sand, 3part 1/8in gravel, 1pt cement and slather that into the final surface of the ramp?

no, i am in the desert.

ive used an inverter + truck to run a concrete mixer, but i hear that combo will ruin tool batteries
...how come that combo will ruin tool batteries, but a 12v ryobi car charger wont?

graveside?

isnt ply like only 20% more expensive than osb?

how would i go about adding a slanted cinderblock "china wall" to the top of this quarterpipe design?

>>2463707
>Unless the second ramp has tighter transition,
why couldnt i reuse the form if multiple quartes have the same transition? my last quarter was 6ft with an 8ft transition, 8 feet wide. then i used the side forms to extend it another 4 feet, but by the end of that, theyre pretty bowed out.

also 2x4's at my rural hardware store were $8/ea not $3/ea

>>2463297
what is the money spent on? are the forms reusable?
i already have gravel and sand for the concrete.

how do i learn the basics on building forms? youtube? find someone to teach me?

how do i build a ramp like this? does it require experience and lots of money in rebar and wood forms? i would like to utalize these 'sono tubes'

...or would it be cheaper/easier just to pay someone to haul in fill.... or reinforce sand with cement?

>You can get small generators from harbor freight
neighbors have generators and concrete mixers, its a pita to borrow them. i have no where to convienently store my own generator.

>How do you plan to use the angle grinder and rotary hammer without a generator? Battery powered tools don't last for shit when you're working with concrete.

i have two 4ah ryobi batteries, and i just bought two more 4ah batteries. im only cutting 1in deep,16linear feet and drill 4sqft in a session. i can just take my time doing it and swap batteries to not over heat. if i run through all three batteries, i throw them on the charger at neighbors house, and then work on something else with the last battery or go smoke cigarettes

also i have a neighbor with dewalt concrete tools who is happy to do this for me, but he is not always home. great guy. he also owns a hydraulic press, i wanna press a 1lb propane can.

would using cement infused sand be similar to using foam as a filler?
would the vibration eventually make the cemented sand fall apart, or does the cemented rock become stronger over time?

$100 bucks should cover gas within 30miles for a dump truck, ya?

>shitsaw dust in tool
i have a shit ryobi angle grinder, i was thinking i would cut a 1inch deep square, ryobi roto hammer a bunch of holes in it and then hammer out the concrete

>silica dust
i have a fullface and regular respirator and n95 cartridges. do i need special silica dust cartridges.
this is post wwii military concrete. is there high risk of asbestos?

the wall will be used for extending the quarterpipe above the pool
this ramp is 6ft high sotting 1.5foot above the 4.5ft tall wall.

I would like to have some 8foot tall sections of quarterpipe

also whats a cheaper alternative to cinderblocks? ive been filling them with 3 to 6in rocks and some shitty half assed home made concrete with less cement than usual.

>I'm a fellow skater and also a mason and I'm glad you are doing things the right way instead of just trying to use feather finish or whatever that garbage is to get a smooth edge. The way you're doing it will last for ages, the easy way only seems to last a few months.
i dont understand most of this but it seems like an angle grinder with a masonary cut off disc should do the trick. i think i might go by a roatry hammer drill today for drilling holes for rebar to conect cinder blocks >>2460195 pic related
>do i need a rotary hammer drill to accomplish this??
> do those cinderblocks actually need to be anchhored in??

Good to know, I have a few of these around, but need a 24v one.

This isn't meant to be an entire level, that'd be awful, this is meant to be a building in a level that you can enter and leave.

So basically,

What I'm trying to do is take this room model that I made in Blender and port it to Unreal Engine with collisions so my character can enter in and out. My past issue was, Unreal would set collisions like a box for models I imported, but now I've learned how to make custom collisions for objects. (I don't use the complex collisions option to prevent performance loss.) I'm currently trying to figure out how I can make collisions for this room model without having to dissect it one by one or recreate it. I've tried to copy/paste it with UCX next to the collision model but that didn't seem to do anything. Any techniques out there?

i found this in a free pile today, its cute. i am going to combine it with sewn up pant legs for screw storage.

the handle is gonna get smashed and broke very quickly. its cute, though

yeah but living in any western country is.
