Steel Industrial Pentagon Table

Pentagon shaped table i have wanted to build,
Made myself a jig and gave it a shot
Have a look at how i built it and don't forget to watch the full youtube video
Also find me on instagram and twitter
You will never guess what this 12mm round bar turned into

Start by cutting 5 lengths for the base of the pentagon 170mm long
Cut another 5 uprights to fit in custom made jig 190mm long
Tack welded all the intersections together
Cut another 5 at 360mm long then cut half way through at the halfway mark and bend to suit form
Tack weld in place all 5 pieces
Out of the jig we have a symmetrical shape taking form
Fully weld all joins and grind and smooth back with a flap disk
Repurposing an old slab of oregon as top ,
Cut out the top with a circle jig on a router
Sit on top of frame to see if size is right ,and fits perfect
Sand all edges to desired effect and its ready for polyurethane clear ,

Coated in water based poly
screw frame to top through 20x20mm steel tabs welded to frame with short phillips screws
Final coat of poly and lave to dry

    How do you make the jig? How about a video tutorial on that? I sure couldn't make that fran without the jig. It's brilliant! Also we got a peek of your son. I assume he's your son. It may have been unitentional, but what a nice treat. Family makes it real.

      Hi Chris. Awesome work on the table. I have looking north and south for abdiy project for a geometric table and yours was the only one I found. Could you please upload a post about how you built the jig, it would really be helpful. Cheers.

    That is AWESOME! I have zero welding skills, but I’m wondering how feasible it would be to make from plumbing pipes (I am thinking copper ones) with threaded ends and joint? Home Depot here in the U.S. will cut pipe to specifications and thread the ends for you. Just curious as this is SO cool!! TIA.

      To me would look too bulky , and you would struggle to have find a pre made piece that screws the intersections together
      good luck

    I think something should be made from that awesome jig! I don't know anything about welding but it was fun to watch.
