About: I'm a retired IT professional and now enjoying life. The most stressful part of my day these days is feeding the chooks and mowing the grass on my Kubi mini tractor. I have always been a tinkerer and handyma...

I saw this puzzle in a novelty shop a while ago and thought I would have a go at making one myself. I didn’t have any suitable timber for the required size other than radiata pine, but I did have some 30mm redwood strips that I have been using as paint stirrers, so I decided I would use them for this project.

Step 1: Sourcing My Materials

Step 2: Making the Frame

I started by cutting them into 150mm lengths (mainly because I could make two from each piece) and glueing them into 5 x 180mm squares as shown. To fit the eye bolts, I cut out sections about 25mm along each side of the centre square and chiselled off each side of the squares that would marry up either side of this square. In hindsight, I should have drilled the holes to accommodate the eye bolts first before glueing as it would have made for a much neater hole. I’m definitely not a craftsman. With that done, I glued all pieces together and gave it a quick sand followed by two coats of clear varnish.

Step 3: Prepare the Eyebolts

I bought the eyebolts from my local hardware store to use as part of this puzzle. Each of the eye bolts was cut to the appropriate length and roughened on the ends with the grinder so as the glue would have something to bind onto.

Step 4: Hiding My Mistakes

I assembled each eye bolt with a washer to tidy up the hole.
On the reverse side, I cut some steel rod and inserted them to hide the mounting holes I made during the construction phase. There is always a way to hide your stuff ups.
For the loop, I cut a length of braided rope and joined the tips by melting with a lighter.

Step 5: Task at Hand

The puzzle now is to remove the rope from the eyebolts – not as easy as it looks.
For those who give up and want the solution, it is included below in step 6.

    Hi, great project. It would be helpful if you went back in the instructable and added some of the missing information from the questions below. Size and length of the eye bolts, where the eyebolts were positioned, how the eye bolts were glued in, etc. Needs a bit of cleanup to actually follow the instructions! Thanks!

    Hi Jonathon,
    Mate, i did answer those questions, look under WoodChuck ans SteveS125 replies. As for the glue, i just used araldite, any glue should be good enough make sure you rough up the end of each eyebolt as mentioned.
    Yes i guess I've got my hands in tge way a bit in the video..sorry about that
    Cheers, Alf

    Question 5 days ago

    Very nice, definitely going to make this! Still trying to understand how the eye-bolts are glued to the frame? It just says glue... wood glue? Epoxy? Can you also include the eye-bolt lengths in the instructions?

    Very cool puzzle. What is the length of each eye-bolt and how far from the corners are the holes drilled.

    Thanks, glad you liked it. The eyebolts were originally 200mm in length, and i cut them three at 120mm, the fourth at 90mm.
    The internal diameter of the eyebolts are 25mm
    The internal length of the square is 115mm, the holes are 25mm in from the side.
    Cheers
