Volleyball Launcher 2 0 SD 480p
Along time ago I made a volleyball launcher so my daughter could practice her setting and I promised myself I would revamp it to make it better. Here is the completed project after 25 years of sitting around my garage and it appears to work better than the original. It is more mobile and is less bulky. You can change the trajectory of the ball easier. Now the next generation, my granddaughters, will be able to carry on the tradition of practicing with the help of this device.

(Redid this video of my pickleball launcher). I decided to make a machine myself because I couldn't afford a market made one. It has help me practice my skills and I can say it's functions well, better than I expected. It has several adjustments to emulate the different aspects of the game. It's my own design but concepts were taken from other sources. It holds about 40 balls and you can adjust...
Collapsible Welding Table SD 480p
มุมมอง 308 หลายเดือนก่อน
Having the challenge of a small shop, I wanted a welding table that would slide under my work bench but not be so low as to be uncomfortable to work on. This is the project in a short video that shows the essential parts that make the welding table collapsible and can be rolled out of the way under my work bench. It has two 110v electric screw type actuators that raise and lower the table top. ...

I personally like short videos because I scan through introductions and blah, blah, blah. So I just gave you the meat of the matter in how I made a bench top stand. There's not a lot to it so I hope this video helps.
Who needs infrastructure funds with bridges like these.

This is how you make due with what you got. My friend Fidel crossed this bridge in Mexico everyday for a month or so to get to a well project. Probably not OSHA approved but it appears he never had a problem getting back and forth. I admit I never would drive the truck.

Simple DIY Ladder Lift Asphalt Shingles on the Roof
มุมมอง 269K6 ปีที่แล้ว
All the Ladder Lifts I saw on TH-cam were too labor intensive and so I designed my own with stuff I had around the house. It took about 90 minutes to make. I was fortunate to have a 110v winch laying around but noticed that Harbor Freight has one with a discount for $135. You may think that is too much to spend and would settle for rooftop delivery but I saved $480 by doing it myself. It's wort...

Any material list?
Thanks, David. I loved it and did a large chunk of my roof in May 2024. I am 67 and it worked beautifully. I used my HF 2000# 12v winch with a seperate power supply. I did have one problem where the pulley ring did bend, I repaired it using a 1" solid iron bar I had available and continued the project. I did it alone using 2 extension ladders, one I climbed, the other for the shingle escalator. Wish I looked at this 5 years prior when doing another roof alone!!
I’ve use TH-cam for so many of my own projects that it’s great to give back and if it helps someone with something that I share it’s great to get feedback like yours. Thanks and stay safe.
Exactly what I was looking for - I can move the shingles up to my roof by hand BUT...being a one man show, I won't have enough energy to do anything else that day if I burn my energy and break my back man handling these up a ladder. Every little thing helps and this is a big one!
I agree, every little bit helps. Just take it slow and easy and not overload the ladder and you’ll be saving your back and energy. Thanks for the comment.
This is awesome! Thanks for sharing! Now I have an excuse to get a winch from HF
Very creative man!!!!👍
just rent or buy a powerr ladder
You have usmc there an your using that?! Seriously 😮 he should be able to strap 3 bundles on an get up that ladder, and back down by the time you're done reading this !! DO YOU HEAR ME !!?? DONT SPEAK ! DONT EVEN LOOK AT ME ! FACE TO DIRT THE BOTH OF YOU ! I WANT THE TOTAL WEIGHT OF SHINGLES USED, IN burpee's! USE YOU'RE BODY WEIGHT, NOW!! UNTIL ITS DONE.!! COCULATE WHILE GIVEN US THE DANCE GO GO GOOOO!!!!
I will be making one of these when I do my roof. No way in hell Im climbing a ladder with a stack of shingles on my shoulder.
Amen! That’s how I felt. Stay safe and glad it’s going to help you.
Ingenious thanks for sharing
ceva simplu si util, manny thanks David...
They make rope hoist blocks with hook latches for like $40. Latch on the top, string it down through and a 4 rope system would have it to ~20lb pulling force. No need for a winch really
Wheres the fun in that? 😂 I Need an excuse for a winch.
Or any pics of how you installed them .
Sorry, I don't have anything more than what is in the video.
What are the requirements for the post in California , anything special ? Dobe blocks etc..
It’s been a while, and each city may vary its requirements. But the 3 inch metal pipe was put in the ground somewhere around 60+ inches. I poured over 2 yards of concrete for the eight post. That’s California with its over regulated requirements.
I could get 3 bundles up easy in the time that took
Great video sir
When pipes hard to take out need to take in the same hole put new pipes without drill bit only using water and flushing to the bottom when sand no going take out 2 pipes in same time no need recovery trucks
i thought great idea .then i seen worker and his hand holding ladder rung . And thought what if eye bolt pulled out at some point .you have a 60lb guiotine.If something can happen it will .so perhaps a light mesh or some thing to stop a hand being placed there and you got a winner . great hack after safety improvement !!
Good point. There is no good reason for him to stand in harms way. The older I get the more I think about how to be more safe when doing anything. Tx
Pinch point occurs at 26 seconds on this video. Homemade or factory produced, always be aware of pinch and shear points on equipment. If the trolley breaks loose with the young man's hands on the ladder rung, all of his fingers will be severed. Of course, it doesn't happen. However the assumption should always be that the equipment failure will happen at some point. The operator loads and then steps away. Hands are kept clear of any pinch or shear points. If equipment failure occurs everyone walks away and has their hands to work another day.
Great observation. He should also step to the side as there is no strong reason to be there after the trolley proceeds upward. Thanks for pointing that out.
How did you protected camera from water?
I tried to seal each joint which eventually leaked because of the water pressure. I saw where someone filled the entire inside with silicone covering all the wires and components - everything but the lens.
Wow!! How much was the winch?
Harbor Freight has one for the regular price of $169
A two and a half foot fine tapered find threaded dart would of got it out first shot
If there is a next time, which I hope there isn't, I'll try that. Tx
Yes! Fucki#@ Yes! I knew I wasn't crazy
No idea that works is crazy but not every idea works in every situation. It worked here. Tx for watching.
How did you power this winch?
It's a 110 volt winch not common but they can be found.
Wow. Thank you. Wow. I’m doing this
I will build my own it great idea 💡🙂💯👏👍
Where's the end of the story then ?
Love it 👍
Brilliant! Yet simple
Cool! Thanks for sharing.
Great, simple solution. Thanks for posting!
Great simple idea. Question. Do you think it would work with a Little Giant Ladder? I'm looking to hoist 100 lbs.
The weight is probably not a problem but if I remember how the Little Giant Ladder is built the locking mechanisms on the side of the ladder rails may be in the way of the guides on the sled. You have to think of the ladder as a train track with no joints, bolts, connection points, etc that would restrict the smooth gliding of the sled. Two parallel 2x4’s on edge as tracks may work but I don’t know your situation. Hope this helps.
Great idea I need to get some drywall in a garage loft and am pushing 70. I’ll just build it a little longer and use a rope. I’ll soap or wax the ladder rails also to make is easier.
I get the pushing 70 thing. Be safe.
Please reinforce those brackets. 2 more maybe.
Not a problem to add more brackets if you want the added security. According to the manufacturer those brackets are rated at 1,000 lbs each. It was never my intent to overload the lift keeping the load at less than two or three bundles ( approximately 250lbs). Better to make more passes up the ladder taking a few extra minutes to get the shingles on the roof safely. Be safe and thanks for your suggestion.
I have watched a lot of these videos and I learn a little more with each one I watch so thank you for taking the time and posting this.
Love it, and you're right, the others are too labor intensive. Excellent design.
We did this several years ago but used a 4 wheeler to pull them up we pulled up 3 bundles at a time...
Awesome! Anything to make the job easier.
I'd like to drill a well in Veracruz, and who do you recommend I go to?
Sorry, we’re not in that area. I hope you find someone.

Thanks you save me a lot building your ladder lift. 😀👍
Great idea! Can you provide a drawing to show how to construct this tool? Thank you!
I'm not sure I can explain it any better then the video shows in detail the design I made. Thanks for your interest.
Very awesome
GENIUS SEEING THEY USUALLY CHARGE $3500 FOR A LADDER LIFT WHICH IS RIDICULOUS ANYONE WOULD KNOW YOU'RE TRING TO MAKE MONEY NOT SPEND IT ON A LIFT OR YOU COULD JUST HIRE A KID FOR THE DAY FOR A $100 BUCKS LIKE I USED TO DO LIKE A DONKEY AND HUMP BUNDLES UP THE LADDER ALL DAY LONG THAT SUCKED BUT GOOD EXPERIENCE!!! WORK SMARTER NOT HARDER AWESOME SIMPLE MACHINE NOW THAT'S STICKING IT TO THE MAN!!!!
Where did you get those post caps? Good looking job!
They came with a package deal from wholesale solar. They sell them individually too on their website
Thank you David! I'm going to build something very like this for my upcoming roofing job. Humping the bundles up onto the roof is the most difficult part by far! I have a homemade steel ladder and will build the sled out of wood with UHMW slides to make it easier. $70 Harbor Freight winch and one of my marine batteries and I am in business!
I hope the project goes well and stay safe. Not sure what UHMW slides are but understand how the concept might reduce friction. Thanks for the contribution.
Where did you buy your winch ?
Wow I've had it for awhile . Probably on Amazon. Superwinch 1500 110 volt
Keeping it simple and cheap!
Yes!
Do you have instructions for building the setting machine?
I do. Send me an email address at edge4him@gmail.com for pictures and a diagram.
I'll second the idea of adding UHMW plastic skids. Easier on the winch, less wear on the ladder uprights (think about wearing away the uprights for a minute...). Self-adhesive UHMW strips are available.
Modify this to use casters, several other videos show their use and it saves all friction.
It took 90 minutes to make that simple ladder lift? I could have made it in a day and a half easy. Great idea.
I know I’m very late to this video but can you explain how you made it?
It would be a very long explaination but basically it works by a air piston that punches the ball out. An air compressor charges the piston cylinder by a pressure valve, that is tripped by a switch.
