These types of nuts have been used by the bicycle industry for years and years. They call them starnuts or steertube nuts. They are used to secure the stim to the steertube of the bicycle. They make a tool designed to make installation very easy. Really cool to see these used for different applications.
That’s really interesting Cory! Thanks for some backstory on them. We love when pieces like this are meant for something totally different but end up working for cool builds with conduit. Thanks for the comment.
Also Rivnuts are used in the auto industry etc. Drill a hole in sheet metal or conduit, then insert proper sized rivnut insert with the special tool and it compresses and secures the threaded rivnut insert which then allows nuts/bolts to thread into it securely.
For the table leg demo, one should add a fender washer to prevent the tube from "digging in" (both during installation and long-term use). DIY Feet: Carriage bolt thru 3/4" hardwood (partially drilled) then fender washer and nut. Another nut against leg to lock height. Inserting an Eye Hole Head Screw (or screw/nut with drilled hole in head) with the starnut and then securing a roll pin thru the conduit and hole should increase pull-out strength. Great Find/Hack for a potentially difficult termination. Well-Done !!!!
FYI, you said you used a drill bit that is slightly larger than the 1\4 inch bolt. This isn't actually necessary. 1\4 inch is the nominal size of the bolt, but the actual size is approximately .2489 inches. Bolts are actually slightly smaller than their size, so a 1\4 inch drill bit hole will fit a quarter inch bolt. This is true of all bolt sizes, they are designed that way. So you actually will get a tighter, nicer fit if you use the same size drill bit. Great content, love the ideas, keep them coming.
Those nut inserts are the same thing used in threadless bicycle forks. To install , take a 2 inch long corresponding bolt , slide it through a shallow tool socket, grab socket with vice grips and now u have an easy way to hammer the insert into the pipe. The vice grips can also act as a depth stop
Once again another great hack. I’d like to use carriage bolts for leveling feet. They have a nice dorm top that doesn’t scratch the floor and they have a wrench flats the same size as the threads...
Also can use 1/2” or 3/4” cane tips on the ends of the tubes to keep from scratching things that the legs rest on. Floor, table, etc. Cane tips from Walmart 4/ $3.97 in the pharmacy section.
Not sure how I found this company but it seems pretty cool. I am working up plans to make an RV awning frame that anchors to the side of the camper rather than using "tent poles" to hold it up when in use. I see a few parts they sell that will probably help bring it all together.
What’s the tensile strength of these inserts? If I used a piece all-thread to couple two joints of conduit, How much force would it take to pull the insert out of the conduit?
Are there any plans to manufacture/supply the threaded inserts for 1/2" EMT conduit too? 3/4" and 1" EMT too big for one of the projects I wanted to do.
Been thinking about doing an suv bed platform similar to this. My fear is that it wouldn't be strong enough where it connects to the wood. Especially if I had company and things got a little crazy? 😋 Any suggestions on how to make it a little more robust?
If the van is a rockin don't come a knockin lol! Honestly I would just recommend adding more of those two hole straps and longer bolts/screws. They do a great job of securing the pipe to wood and the more you have, the stronger they will be.
Hi there, thanks for the question. We like to use EMT Conduit for building things like desks and greenhouses. These are really useful for DIY projects but not for electrical projects.
PLEASE MAKE THESE for 1/2" size conduit. There are millions of old folks with wheeled carts, used for shopping, that have the crappiest wheels. If I could just put one of those inside a 1/2" size conduit, using 3/8 X 16 thread, I could thread on new polyurethane swivel wheels. These carts are made with very thin tubing and even 1/2" is bigger than any tube, but 1/2" could be shimmed or rigged to it fairly easily... but trying to go up to 3/4" is too much. I've been looking for something, because I don't want to have to rely on J.B. Weld to hold a nut I could screw the wheels into, and then try to carry upwards of 125Lbs from a supermarket, back home. The original wheels only lasted 4 months and couldn't swivel. I will gladly make a video of a finished product and show the vast improvement to the cart.
The 'nuts' for the wheels are a little small, and I'm guessing JB Weld would probably hold. If you're talking about their mounts for 3/4 inch conduit... I supposed the 1/2 inch pipe could be flared out, but might weaken it... I'm a pretty amateur mechanic & have bad luck, when it comes to Gerry-rigging, lol Hmm, maybe I can drill a small, shallow holes into the side of the nut and use a couple of short screws to secure it to the 1/2 conduit, from the outside... that and JB lol.@@phazerave
Thanks for the comment and question. I don't have an exact number unfortunately, but I would guess at least 100 pounds. The metal spring clips really grip and dig into the inside of the pipe.
How many uses could I possibly have for a 4" piece of conduit? You need to make a video showing practical uses for your product. All you really did was show how it inserts into conduit. It looked like you were saying it is only used for a small piece of conduit.

maker pipe getting better and better each video
Thanks for the feedback 🤙

Yeppers! Was gonna say the same thing.

Congrats on your company. Great inventors helper.
Thanks so much Susan!
Dang. This one got me excited for some possibilities!
There are tons of cool ideas! Can't wait to see how you use it.

Oh interesting, thanks for the suggestion. I'll have to give that method a try!
Add a fender washers between the plywood and the EMT to avoid the pipe digging into the wood
Oh my God, I love you! You just solved a big problem for me.
That's great to hear. Glad it was helpful to you John!
Once again another great hack. I’d like to use carriage bolts for leveling feet. They have a nice dorm top that doesn’t scratch the floor and they have a wrench flats the same size as the threads...
That’s definitively a good option for leveling feet! Can’t wait to see how everyone uses the inserts 👌
@Cory Hickson thank you so much i've been trying to find these but had no idea what the name was lol
If your doing longer lenghts of pipe 2 or 3 feet long you can use a woodworkers pipe clamps
That’s a great idea! Thanks for the tip 👍
Very interesting 👍
A great tip! Definitely using this.
Awesome! Glad it was helpful 👍

Nice vice. Appears to not be offshore?

Brilliant
Really Cool. Arbor Press might make things faster, next best would be electric hydraulic RAM with up down, no spring release crapola.
Are there any plans to manufacture/supply the threaded inserts for 1/2" EMT conduit too? 3/4" and 1" EMT too big for one of the projects I wanted to do.
We will at some point but not at the moment. Here are some that I’ve used that fit with 1/2” EMT. www.mcmaster.com/product/94290A510
@@MakerPipe Thanks!
Will this work with black pipe, I need to attach casters.
Unfortunately, the ones we sell won't fit inside of black pipe but you can find different sizes on McMaster Carr

How do you pull electrical wire through it now?

I second this, Im curious tho, seems like you might be able to just jam it in a 1/2" conduit.... couldnt you?

I could us the short peice and push a treaded Pipe Insert into both ends, the use it to join two long pipes for a large window curtian! Hmmm...
That would be cool!
What a neat idea.
I would imagine it may be possible to drag it through the pipe if you put a piece of all thread into a drill.
How much weight can one double star nut handle before it slips?
Thanks for the comment and question. I don't have an exact number unfortunately, but I would guess at least 100 pounds. The metal spring clips really grip and dig into the inside of the pipe.
@@MakerPipe thanks ,already ordered 10 packs plus another builder kit. the first ordered products are fantastic.
A washer the size of the end of the conduit with an extra nut will also stop that inner mount from going further into the tube
Bar clamps will allow this method in longer pieces.
How many uses could I possibly have for a 4" piece of conduit?
You need to make a video showing practical uses for your product.
All you really did was show how it inserts into conduit. It looked like you were saying it is only used for a small piece of conduit.
Check out the other videos on their channel. They have a lot of great build ideas.
Click bait. There's no hack here, just a product that they want you to buy.
