Great job on making the core assembly. That's the hardest part to get straight. I use a batch design of 2/3rds sand to 1/3 stone or gravel. You should have a minimum of 10% Portland type 1 cement in your batch. The strength comes from the stone in the unit and how tight you compact it if using a low moisture mix. In modern times, ASTM requires 2000 psi minimum compressive strength which all units should meet that you buy from a producer or box store. I had my antique block that I make by hand tested and they came back at an average of 4,800 psi, so it is doable making them by hand. It's a fun hobby but also a labor of love!
What kind of mix do you use for your molds? I just got into the hobby and started out with the concrete mix they sell that home depot. I feel like it has to many pea pebbles inside of the concrete mix for my molds. Thank you for your time.
The mix is about three parts sand to one part Portland cement. Then you mix in enough water to make it about the same consistency as the damp sand on a beach that you would make a sandcastle out of. The mold uses a zero slump mix where one mold can be used repetitively. Unlike the molds that you would let it sit overnight. Overnight molds you can use a wetter mix even concrete if you like. There is not just different mixes there is different slumps. Paver molds and my molds use a zero slump. If you were putting in a driveway or a sidewalk you would probably use an 5 or a 6 inch slump. If you were filling steel-reinforced concrete blocks you would use a 7 or 8 inch slump.
At $1,,50 per block at Lowe's is this process REALLY worth it? what are you saving? I can't see the value unless there are no stores nearby , but STILL you have to lug in MANY bags of concrete if you're laying a number of block.. Good luck.
I know this is old, but using something to agitate the mold (an old back massager, a palm sander, basically anything that vibrates) will help the material settle into place
That's a good point and probably would work, but if I ever need blocks again I'll make it all one piece flip it over fill it with a shovel and pack the mud into place with a shovel and then scrape it off flip the mold back over and pull it off the formed block and repeat the process. Also important to remember that every block I made I used and is still in great shape and filled with concrete holding up my garage.
@@LouLovesLyrics agitation just helps any air pockets get filled in. I have no doubt your blocks are in great shape! I have physical limitations that mean I have to look for less physically intense ways of approaching projects
isfel a lot of people have offered to buy them and if you're anywhere near Gainesville Florida I would gladly show you this one. but it's very impractical considering you can buy the same block from Home Depot for about a $1.35 a piece. now if you're really seriously interested you can buy a metric one. that's where I got the idea from they're a little over three hundred bucks, and you can make them fit standard plans.
Yes making the mold was very laborious. It took almost a week. It was my second project teaching myself how to weld. Got another project coming this weekend.
I will did it out of 14 gauge steel using a masonry block as a guide. I bought a Lincoln 225 stick welder and a Eastwood 175 Mig. I'm teaching myself how to weld this is just one of the projects I came up with the Goof Off. it's funny how people hate on you when you post these videos. what could be more ignorant then the idiot below you saying I bought it when he has no idea what he's talking about. it's not really efficient. It is easier to buy blocks from Home Depot. but four pennies I have built as foundation for my shed and a foundation for my AC.
+Carlos TC you get it from me in Florida or I ship you one. this is just the prototype. I can weld you up one. if you notice it is pulling out part of the web. I have fabricated the solution. I just haven't made the video of it working. so in this video it shows a three peace mold. it is now a four peace.
Use that hammer more on the sides and use a spray releasing agent like silicon ore animal fat and you can increase the quality. Good idea with 2 or three people you could turn out 100 blocks a or so a day good for remote and under development country's. Btw use a wood hammer. 😁👍
Ronald Brown good input insightful genuinely trying to be helpful. I got all the sand I want for free so I'm trying to keep this cost down. I figured it's about 8 or 9 cents a block. my next project it's going to be Doric column molds. trying to work on some ideas about how to taper a welded cylindrical column, any suggestions? I was thinking about building the column completely cylindrical and then making Rip's down the side and re welding them to get the proper taper.
it's about eight parts and one and a half parts cement and a half part pea Rock. ad just enough water to make it damp. if it's runny at all it will not work. if you wanted to make a simple box you can make your own bricks easy custom sizes. I wouldn't suggest building a block mold like this. it took me probably about 30 hours to build it. I live almost next door to one of North Florida's largest sand mines the Keuka sand plant. so I sit on a acre and a half of pure blonde sand.
compacted well enough to fill with concrete which is what most block is used for. and there's two Block in 10 minutes so it looks like math isn't your best subject.
@@roystonvanwyk5086 you don't know what you're talkin about. I made a machine from scrap metal that actually makes blocks. You can't name one other person that pulled that off.
@@LouLovesLyrics ok.. Good.. But whats the use if the brick look like that.. A standard brick does not look like that.. You should do it.. Again and again.. And more and more.. To fix the problem.. Your a engineer.. Bro.. You can fix it
You must thank your block association don’t have any standards for concrete blocks ，or who dare to buy your concrete hollow block? Look at my block mold
And by the way I advise people that Home Depot sells the block that my mold was created from for $1.35. I also have written that I myself instead of taking the time to mold blocks to finish a project, I personally drive to Home Depot and bought some of those block to save time. I've never sold any block and every block I've used is full of steel-reinforced concrete and was used on the property that I own.
@@HenryBlockMachineGroup the quality doesn't matter if it's full of steel-reinforced concrete. It doesn't matter if it's made of cane sugar and dissolves away the first rain. Which I assure you hasn't happened. All the block that I made have been used. And are still holding steel-reinforced concrete. So let's just say you sound like you're jealous and you don't know what you're talkin about. The machine is not for sale. The blocks are not for sale. It was my first welding project. After I taught myself to weld. I don't give a s*** about the block mold. It is rusting in my shed.
@@LouLovesLyrics i know that the steel reinforcement can support more solid to the building wall, but , inside the block material, only cement, sand is not enough to guarantee its density, that is better to feed crushed stones
It is for demonstration purposes only. If I was trying to be fast I wouldn't be working on the ground. I have a bunch more mud made up and I'd be working off a bench. But why don't you buy a welder teach yourself how to weld. Then design a block machine in your head manufacturer it and then let's see how fast you are. Okay?
@@LouLovesLyrics don't let the arse holes on here get to you. We're sitting on our behinds watching a video of you working that you put up to help us. Everybody thinks they're an expert when they don't have to do the work

Having spent almost 50-years in the mortar trades, it is painful for me to watch you working mortar with your bare hands. That is an invitation for cement poisoning, and a dangerous practice to be displaying in a YT video. You would be thrown off a real job-site for not wearing gloves to do this.
So, during the Nixon administration you were working with mortar and yall never worked with out gloves?

The core assembly was assembled and welded inside a block from home Depot then simply pulled out. Easy pesy
How about welding Handel's on the sides to lift and drop to help the cement mixture to fill the mold quickly

Oh yeah you don't need the Pea Rock if you're just filling molds.

Thank you for sharing the video; curious, what is the cost of material per each block?
i figured it up at 12 cents. but my land is on top of pure blond sand. so I have no cost on sand.
That's amazing!

Either its too tough making these blocks with the shown mould or the person is not used to do the work
I like your molder
Thanks.
nice work boots.
Do you wear work boots in your front yard?
@@LouLovesLyrics it depends on the work I'm doing. For this job, I think the "boots" you're wearing are just fine!
How much for one mold? If you can make one or two I'm willing to pay

What's your website for the cinder block mold
Reginald Middleton don't have one my friend it was just a welding project. it took me almost a week to produce.
And . . . how much it cost ?
+Carlos TC $250 + shipping but i will have to set up an ebay account. unless you are nearby Gainesville FL.

My friend, you have to deform the block upside down
Marcos Gobira yes the thick side with the handle it's down and the thin side is up. my mold would not slide off otherwise.
He has never produced a hollow block. Completely inadequate and partly no concrete compaction. So you can produce 3 stones per hour.
