You should find a way to make it work when PUSHED as well as pulled? Just using the same frame idea (as in the arch over the hole, inside the block's internals), but using a more rigid piece of flexible metal, meaning it will more reliably push out the bolt on the other side? Just a strong enough, 'precisely calculated' (well, enough to match the arch's rounded 'length' anyway) strip of bendy metal should work.
@@bobh3300 Well yes, that is effectively what I meant. But an uncoiled, flexible piece of bent metal would likely work better as it'd be less 'springy' in visual appearance.
Weld/glue a solid half-rectangle and increase the internal area cut out to fit. It will not have any play. Also as others suggested, split the wood. __|````o````|___
I'd replace the rope with a welded metal loop. Extend the slot inside enough to let the loop slide further. Bolt will then feel real if you hand it to unknowing observer.
One of the things I noticed that gives away the trick is that one "end" of the bolt can wobble in the hole without the other side wobbling. Perhaps having them inside sleeves (metal, plastic) would provide a tighter fit and stop the wobble.

Could have a u shaped linkage overthe hole with a spur gear train on each vertical leg and a layshaft across the top. You could then push and pull from either end and also turn either end and get coresponding rotary movement at the other. You’d have to keep back lash to a minimum though. An interesting idea though
I love it. The only thing I might change is using a nail instead of a bolt. Using a lot invites twisting and when the other side doesn’t twist it breaks the illusion
I wonder if you used a spring to join the two halves if you could push and pull the bolt from the same end? Turns of the spring might feel like the threads of the bolt. Neat project.
Good save with the aluminum sleeve, traits of a true craftsman which appears to becoming extinct. I consider myself a craftsman I’ve had to dig myself out of many dilemmas👍
Like many commented: One long bolt bent up, over, down and out the other end with the inside hollowed out to allow sufficient movement......oh and frankly, drill a smaller hole in the center........the metal tube raises questions ! Masking the wood joints would require some genius work but I'm sure the expert wood working community could answer the call. Enjoyed the video.......I love these little knick knack projects !
masking the wood joint is easy if you use a different type of wood or different grain orientation - you could spit the wood alone the grain and reglue it without noticing - or just use multiplex or any other type of plywood, this will do the trick. the deluxe version would be a machined metal piece - brass for example and soldered back together with an invisible joint
Thanks for the ideas, Philippe! I appreciate you sharing them in a constructive and kind way. Lots of negative comments on this one! Thanks for watching, I'm glad you enjoyed it!
@@dkbuilds Just invite the negative commenters to make a video of their genius work then we'll judge them ! Don't waste time on them.....keep up the great videos, everyone else enjoys them !
Hmmm. Maybe a square channel and wire holding the two pieces of bolt. That way it may be possible to both push and pull the bolt pieces. I haven't thought it thru yet, so not sure if I'm on to something. Gotta think about it. Neat trick.
Thanks for the comment, Don! Yeah I'm trying to think of ways where both push and pull are possible. If I had a welder I'd just create a long bolt shaped like --__-- and make a square channel like you suggest. Maybe epoxy would work instead of welding...
Dave, epoxy would probably work fine. Or, you could make the square connector out of some hard wood and use tiny dovetails for the joints and epoxy to connect the bolt pieces to the wood. :-) Hey, I'm here to make work for you......
That's the ticket! Square channel, with a U shaped 'connector. If the bolt is linked to the connector with a 'loose' attachment of some kind (tiny cotter pins?) then the bolt head and end could rotate yet still push/pull each other. The real trick would be to make the rotation occur at both ends simultaneously to complete the illusion. Some mechanical genius above my pay grade will have to figure out that challenge! :)
The better trick. Would be use a small flex cable attacked to both pieces. Like I use in my RC hobbies. Along with a small bent stuffing tube it runs through. So when you turn the bolt, the other ends turns.
Perhaps use a big nail instead of a bolt then there isn't the compulsion to try and turn the bolt. Drill the holes so it just fits the nail, then link it with a metal rod, soldered, brazed or welded to complete the link. As someone else said, split rather than cut the block of wood to disguise the join then sand well when glued together again. Could be a good illusion if executed well.
Use a larger piece of wood with nice straight grain. Instead of cutting with a saw, split it lengthwise with a chisel till it splits in the middle. Do your working inside and glue shut. Saw to final dimension to remove chisel marks and sand. That should give you a near-invisible seam. Other suggestions below would help with the illusion regarding bolt wobble and movement. Great instruction video, many thanks.
I thought it was a bit bland but seeing "asking for improvements" and seeing suggestions in the comments won me for like and sub... love to see the improvements
I was thinking you might use a flexible cable, like the old speedometer cables, to connect the two ends of the bolt. That way you could not only push and pull, but also turn one side and the other side would turn the same. Not sure if a cable is flexible enough to make that curve and still turn though, and it might require welding the two bolt ends to the cable.
How about replacing the bolt with a tea spoon or screw driver of something. The bolt makes us all want to twist it. The idea rocks! I enjoyed the video!
Very good point third, I never thought about that. Maybe I'll try a different object if I build this again. Thanks for watching, I'm glad you liked it!!
That's what I did on my first prototype actually... but then when I was trying to route out the channel around it, I broke the wall of the hole even though I was a full 1/4" away from it. I was hoping to drill at the end so there's more support to prevent chipout while routing, but then I missed the mark :(
@@dkbuilds Try drilling a very small hole right through the centre (before routing out the channel) - then use that hole as the centre for the Forstner bit, to guarantee accuracy.
You can't push one end, only pull it. You need to improve the internal mechanism to make it a pull and push trick. It requires an internal linkage, rather than a piece of string.
Amazing - i'll guess i build one myself, but i have an idea for improvement 1) use multiplex instead of solid wood, you you can mask the fact, that you cut it in half and glued it back together, it looks 2) instead of a piece of twine use a piece of u bracket or a solid wire (coat hanger) for example - so you can push and pull it from both sides without "delay" or yanking it 3) add a bit of thickness to the material so you can make it possible for the u-shape mentioned in #2 to rotate/turn the bolt (not freely (360°) but if done properly you can make it turn by lets say 75° if and have still enough material left to stabilize the center pice without showing
Great idea.. Now make it so that when you turn the screw, it turns at the other end.. There might be a better way, but here's a start. Step 1. Drill the BIG hole through the center first. Step 2. Then split the two halves apart. Step 3. Cut a rectangle slot around the BIG hole. Make the rectangle so it is a thin groove above and below the hole and wide at each end in the direction the bolt moves. Step 4. Get a piece of metal bent into a rectangle that is shorter than the groove so it moves inside the cutout groove. Step 5. Cut a plastic staw to the length of the rectangle and tape or glue it down along the long sides of the rectangle. Step 6. Drill a hole in the center of the short side of the metal big enough for the bolt to go through, then attach the nuts to each end of the metal rectangle over the holes and screw the bolts into the nuts 10 turns. Step 7. get a long piece of string and glue it to the first bolt and wait for it to dry. Step 8. after dry, wrap the string around the bolt about 10 times clockwise. Step 9. loop it around the top of the rectangle and feed it through the straw to the other bolt and wrap it 10 times. Step 10. loop it around the bottom of the rectangle and feed it through the first bolt and wrap it clockwise 10 more times. Try not to cover the first wrap of string. Now glue the end of the 10th loop to the bolt.
Maybe use a spring instead of the wire, that way you'll be able to also push it which will help sell the illusion even better. You can screw the ends of the bolt into the spring eliminating the nuts and this also allows for a narrower channel so it doesn't wobble as much.
Install nuts on the outer edges with grooves behind them to allow 1/2" of travel in and out. then weld a strong spring on the inside ends of the bolts to travel through a groove in the wood block: this time make a jig to cut that groove. Glue the block back together and drill your hole in the middle, well clear of the groove. Make it look like the block was never cut by splitting the wood with a knife, then dressing the ends afterwards. Cut your groove, epoxy the nuts in their places with the bolt/spring assembly in them and glue the whole thing back together. This way you turn the screw and it goes back and forth. Also make the hole for the bolt threads tight and make sure it is aligned well with the other end.
You need to put a spring on both bolts between the nut on the inside and the inside of the wood so that when you pull and release one 'end' of the bolt, the spring on the one not being pulled will push it back into place making it appear more convincing!
You have play in the bolt that gives away the fact it is not one piece. That could be fixed by actually taking a longer piece of threaded rod and bending it round the hole as someone else has said, you would need to hollow out the wood to allow it to move back and forth. However the bolt cannot turn which is a great shame, as it should do so, and indeed if anyone can think of a way of making it that really would be an impressive illusion. I think I would choose a flat object instead (like a table knife) which goes into a slot in the block, but you would then need to weld a semi circle of metal to its two parts to be hidden inside the wood.
Why not drill the center hole first? You could use a stiff wire instead of string to push and pull the bolt. Or better, solder a piece of sheet metal cut to shape. A keyway could help keep the ends aligned.
That's a good point Ant. I didn't drill the hole first because I was worried I would blow through it when routing out the groove on the inside. In retrospect I could have drilled it first... might try that next time. Thanks for sharing!
This would work better if instead of a string you used a curved piece of metal so you could push and pull on either end and it would move back and forth. This way if you can only pull. If you were to push either end the other end wouldn't move.
OK.. My Idea to improve this... but not as simple... Clip ring to stop bolts exiting either end. 2 trains of an odd number of gears meshed top to top of the bolts, and bottom to bottom. Pulling left bolt rotates 1st and last top gear anti clockwise, and bottom 1st and last clockwise. Result is right bolt driven out by right top and bottom gears... (Same thing when pushed back in)... BUT... Rotating the left bolt (say anti clockwise undo) should rotate the top and bottom left and right gears anti clockwise... but this would just bind up... So this is where the hard part comes in... Drill the end of the bolts and add a dual direction wound piece of cable soldiered in the hole like your piece of string. (bike brake wire is wound in one direction,.. you need something with a 2nd winding in the opposite direction otherwise turning in one direction will spread the wire ) the wire "Should" rotate the other bolt overcoming the binding... If that fails you could try a different approach... (which I think is actually the easiest.. but harder to find parts... 3D printer???? mill the end of the bolts to a thin axle. Jam a longitudinal spline gear on each, make a channel of these gears with the bolt gear slotted into one end... make a shaft with a spline gear either end joining the 2 channels.... the result SHOULD now work when you pull/push as the channel (looking a bit like a short machine gun magazine) is locked either side of the bolts gear, and the other end of the channel is locked to the gear on the end of the shaft... which is attached to the other,channel,bolt yadda yadda. and when you rotate the bolt.. it rolls the gears... doesn't matter how many (least as possible) as both sides match rotation, so will the bolt. I made my own "Trick" block when I was a kid (After seeing a similar trick block. The trick... a block with a string through a drilled hole and out the other side. String passes freely knotted end to knotted end unobstructed. Pick up both knots, hold one hand up and one down... block slides down, switch hands... down up.... block slides down,.... do it again but then block magically stops on its way down... you can make it start stop... Hand it to the guest.. nothing they do works, block just drops. The secret.. Drill hole through block. Cut the block in 2. Drill big hole inside both halves but not right through to the outside. put a bent nail in the inside of one bent over in the shape of a 7 (note a 7 makes a hook) with the hook lower than the centre of the through hole. How to do the trick, push the string in both ends and spin the loose string clockwise to hook it (you need to make sure you know which end is which as spinning the string the other way un hooks it). once the string is 'hooked' holding loosly will allow the block to drop... holding tight binds the string in a V with the holes either side of the hook being the bottom of the V. Phew...
Just don't ever put it in the hands of another - because, for certain, they will do a "pull - push" rather than a "pull - pull" and your fraud will be exposed. To improve this I would square off the 'detour' giving it extended 'slide' room on either end. Then I would bend (or construct) a bolt with four 90 degree turns. Then, you could hand it to anyone and they could "push - pull" to their heart's content. This would also mean you do not need the bolt 'stopper' nuts on the inside - however, I would at least weld one to the threaded end of the bolt on the outside of the block to provide a reason the bolt can not be removed completely. You may use a second nut if you do not want the Head end of the bolt to be pushed all the way to the wood.
Damn well said Scott. Really appreciate you sharing a positive comment. The video was clearly a gimmick and just for fun and I'm getting hate rained down upon me! Thanks for watching and for sticking up for me!
Nice amateur way to do this, keep practicing m you’ll get better with designs when you’re sliding the bolt, I can see the bolt wiggle giving away it has been cut, hollow out the center a little more, and use solid material to hold both end instead of string
Thanks for the input Brian! I have a few videos where I speak and a few where I don't, I am experimenting to see what users like best. I will consider your opinion for future videos!

Bend a U in the middle of the bolt around the hole.
Cool idea. The only thing I would change would be to split the board instead of cut it. That way the glue seam would be less visible.
Good idea, Hatch! I'll try that next time. Should work well especially if the wood has a nice straight grain.
Hatchmadeit - I like your idea. Splitting a longer 2x4 and cutting a smaller section would hide (cut off) the mark made where the wood was split.

Step 7. get a long piece of string and glue it to the first bolt and wait for it to dry.
Step 8. after dry, wrap the string around the bolt about 10 times clockwise.
Step 9. loop it around the top of the rectangle and feed it through the straw to the other bolt and wrap it 10 times.
Step 10. loop it around the bottom of the rectangle and feed it through the first bolt and wrap it clockwise 10 more times.
Try not to cover the first wrap of string. Now glue the end of the 10th loop to the bolt.

Cut your groove, epoxy the nuts in their places with the bolt/spring assembly in them and glue the whole thing back together. This way you turn the screw and it goes back and forth. Also make the hole for the bolt threads tight and make sure it is aligned well with the other end.
Wow interesting idea, thanks for sharing ladmyre! I like your idea of a jig to cut the groove too.
You need to put a spring on both bolts between the nut on the inside and the inside of the wood so that when you pull and release one 'end' of the bolt, the spring on the one not being pulled will push it back into place making it appear more convincing!
Ooh a spring is an interesting idea. Thanks for the idea, reckon!
You have play in the bolt that gives away the fact it is not one piece. That could be fixed by actually taking a longer piece of threaded rod and bending it round the hole as someone else has said, you would need to hollow out the wood to allow it to move back and forth. However the bolt cannot turn which is a great shame, as it should do so, and indeed if anyone can think of a way of making it that really would be an impressive illusion. I think I would choose a flat object instead (like a table knife) which goes into a slot in the block, but you would then need to weld a semi circle of metal to its two parts to be hidden inside the wood.
Very good point, nice observation Stephen. Thanks for the suggestion on how to improve it!
How to improve it? Give the bolts a proper bearing so they don't tilt and connect them with a wire. There's so much space, no need for a string.
Good tip, thanks Notes!
Most people would turn the bolt and discover the other side doesn't turn before they would pull on it.
Yeah that may be true. Do you have a recommended solution to fix that?
@@dkbuilds I would try a 20D 4" nail or bigger if they make them. Anything without threads might work.
Wouldn't it be better to use a rigid wire instead of twine? That way you could both push and pull on only one end.
That's a good idea, thanks for sharing Sans!
Problem is that pushing won't work
Yep good point pouzzler.
i m a carpenter love u sir
Thank you so much BW!!
I knew what was going to happen before I even watched this..but still good content kool video
Glad you liked it Brett!
Why not drill the center hole first? You could use a stiff wire instead of string to push and pull the bolt. Or better, solder a piece of sheet metal cut to shape. A keyway could help keep the ends aligned.
That's a good point Ant. I didn't drill the hole first because I was worried I would blow through it when routing out the groove on the inside. In retrospect I could have drilled it first... might try that next time. Thanks for sharing!
Cool video, but why not just heat the bolt and bend it around a pipe? That's easier, tighter, and would even still ohm.
Wow I hadn't thought of that! I'm a woodworker not a metalworker so I never even considered that. Thanks for sharing John!
@@dkbuilds I’m a metal worker not a wood worker, so I never know how ya’ll get the wood to cooperate, LOL.
Make one where you can both PUSH and pull the bolt......?
Good idea. Any recommendations how to do that?
This would work better if instead of a string you used a curved piece of metal so you could push and pull on either end and it would move back and forth. This way if you can only pull. If you were to push either end the other end wouldn't move.
Very good point. Thank you for the constructive criticism Thane!
i showed this video to my 8 year old niece.. she laughed and said "thats stupid."..
Haha sounds like your niece has good taste! Now go show her all my other videos and see what she thinks :)
OK.. My Idea to improve this... but not as simple...
Clip ring to stop bolts exiting either end.
2 trains of an odd number of gears meshed top to top of the bolts, and bottom to bottom. Pulling left bolt rotates 1st and last top gear anti clockwise, and bottom 1st and last clockwise.
Result is right bolt driven out by right top and bottom gears... (Same thing when pushed back in)...
BUT... Rotating the left bolt (say anti clockwise undo) should rotate the top and bottom left and right gears anti clockwise... but this would just bind up...
So this is where the hard part comes in...
Drill the end of the bolts and add a dual direction wound piece of cable soldiered in the hole like your piece of string.
(bike brake wire is wound in one direction,.. you need something with a 2nd winding in the opposite direction otherwise turning in one direction will spread the wire )
the wire "Should" rotate the other bolt overcoming the binding...
If that fails you could try a different approach... (which I think is actually the easiest.. but harder to find parts... 3D printer????
mill the end of the bolts to a thin axle. Jam a longitudinal spline gear on each, make a channel of these gears with the bolt gear slotted into one end... make a shaft with a spline gear either end joining the 2 channels....
the result SHOULD now work when you pull/push as the channel (looking a bit like a short machine gun magazine) is locked either side of the bolts gear, and the other end of the channel is locked to the gear on the end of the shaft... which is attached to the other,channel,bolt yadda yadda.
and when you rotate the bolt.. it rolls the gears... doesn't matter how many (least as possible) as both sides match rotation, so will the bolt.
I made my own "Trick" block when I was a kid (After seeing a similar trick block.
The trick... a block with a string through a drilled hole and out the other side. String passes freely knotted end to knotted end unobstructed.
Pick up both knots, hold one hand up and one down... block slides down, switch hands... down up.... block slides down,....
do it again but then block magically stops on its way down... you can make it start stop... Hand it to the guest.. nothing they do works, block just drops.
The secret.. Drill hole through block. Cut the block in 2. Drill big hole inside both halves but not right through to the outside.
put a bent nail in the inside of one bent over in the shape of a 7 (note a 7 makes a hook) with the hook lower than the centre of the through hole.
How to do the trick, push the string in both ends and spin the loose string clockwise to hook it (you need to make sure you know which end is which as spinning the string the other way un hooks it).
once the string is 'hooked' holding loosly will allow the block to drop... holding tight binds the string in a V with the holes either side of the hook being the bottom of the V.
Phew...
Wow, thank you for the detailed response Butler! Lots of great ideas in there! The spinning trick sounds really cool!
@@dkbuilds If only I put the time into actually making things instead of theorizing then going off on a tangent.
Cute!
😇
love it
Thank you zaster!
Nice!💜
Thank you Jason!
if you used metal framing the bolt would move on both a pull and a push......and stain the wood to hide your seams
Thanks for the advice Robert!
Thumbs up if for no other reason than 4:17. 😆 I feel your pain!
Hahaha thank you df!! Happens to the best of us :)
The illusion works only when the bolt is pulled. Pushing does not move the other side.
Good point Spark. How would you recommend I make it so pushing works too?
@@dkbuilds don’t cut the bolt and run it though the hole.
nice nice .....
Thank you Knasterman!
Just don't ever put it in the hands of another - because, for certain, they will do a "pull - push" rather than a "pull - pull" and your fraud will be exposed. To improve this I would square off the 'detour' giving it extended 'slide' room on either end. Then I would bend (or construct) a bolt with four 90 degree turns. Then, you could hand it to anyone and they could "push - pull" to their heart's content. This would also mean you do not need the bolt 'stopper' nuts on the inside - however, I would at least weld one to the threaded end of the bolt on the outside of the block to provide a reason the bolt can not be removed completely. You may use a second nut if you do not want the Head end of the bolt to be pushed all the way to the wood.
Good ideas, thanks for sharing MCM!
try a nitinol wire instead of a string
Ooh that's a great idea! Thanks for sharing Shari
So sharpin my chisels b4 I do this and let's see what else nope its perfect time to go replicate it
Good luck, if you replicate it let me know how it turns out Sam!
Somehow try and make it so that you can push one side and not just pull the other.
Good idea Brendan! Any recommendation how I could do that?
Brendan - If you read other comments you'd find several suggestions on how to do just that.
Neat!
Thanks Super!
Make the hole in the middle smaller next time...
Good idea userbosco!

Just so you’re aware, the preview clip the RUclips app provides gives away the “secret.”
Oh no! Not sure I can change that. Thanks for the heads up Streety!
A lot of impossible vanishing sliding bolt experts here. This video must have been shown by the keynote speaker at their recent convention.
Damn well said Scott. Really appreciate you sharing a positive comment. The video was clearly a gimmick and just for fun and I'm getting hate rained down upon me! Thanks for watching and for sticking up for me!
Bicycle brake cable
Ooh that's an interesting idea. That should work!
изготовить сплошной болт в форме дуги, тоже не большое-то дело :P
Это очень хорошая идея! Я плотник, а не слесарь, поэтому я этого не знал: D
impossible ...usefull
Thanks Jack!
You need narration!
Thanks for the feedback!
Oh please
😇
instead of sawing it in half I would have split the wood with a hatchet.
That’s a great idea!
Make the hole smaller.....one you put metal pipe in you can tell 100% fake....cuz bolt not hitting metal
Thanks for the idea Barry maybe I'll try that!
But... it won’t turn... what’s a screw that doesn’t turn...
Good point, maybe I should have used a nail!
Reminds me of my ex:
She was able to pull me back and forth, as well as push me around... even though at the core, there was only an empty marriage.
Yikes! Thanks for watching Wall!
Nice amateur way to do this, keep practicing m you’ll get better with designs
when you’re sliding the bolt, I can see the bolt wiggle giving away it has been cut, hollow out the center a little more, and use solid material to hold both end instead of string
Thanks for the tip Shawn!

Too many things wrong with this trick.
Its not very convincing

Yeah you've got a good point. Any recommendations how to make it more convincing?

Pulling it back and forth is one thing... try turning it 🙂
Or pushing it.
Yes true that's a definite limitation. I'll try to improve it if I build another version. Thanks for sharing Alex!
Great vid. But you could just use real magic instead.
Good point Fred! I'll try that next time 😝

Good clickbait. If you had started with the actual trick I wouldn’t have bothered to watch. Thought it involved turning the bolts, not just pulling.
Thanks I guess!
it doesn't do anything though but you can look at it.
True, you can look at it!
