Balazs I-Box Platform

Here's some photos of how to modify a Balazs I-box to have the swivel screws run through the drum. There's loys of pictures, so I'll break it into two separate posts.

So here's what's going on:
Balazs has the 4 small holes drilled where the swivel would be attached, but these holes are very small, intended for small wood screws.

Use a straight edge to draw lines from the centers of these holes to creat a square. Then, determine the midpoint of each line, and put a mark. Now draw a longer line that connects parallel midpoints, it should look like crosshairs. Place the swivel on the drum and line it up with the "crosshairs" you created. Center the swivel so that the lines run through the center of the swivel's holes, and mark these hole locations.

Go ahead and drill the 4 new holes with 1/4" drill bit (a pilot hole helps with accuracy). Then, place the drum on the steel platform frame, and snug up the bolts just enough to hold the drum in place. Run the drill bit through the 1/4" holes in the drum, but just enough to leave a small mark on the steel. Remove the drum and go ahead and drill these marks on the steel with a 1/4" bit. 2 of the holes will come through in the steel tubes, so remove the plastic plugs with a flat head screwdriver.

Attach the drum to the frame, and tighten the bolts. Use four 2 1/2" - 3" machine screws with washers and lock nuts to secure the swivel. Pop the plastic plugs back in, and you are ready to go.

If anyone wants to run the swivel screws through the drum/steel, I made a printable template. Everything is to scale, so just check that the 4" and 9" dimensions are accurate before marking anything.

That's genius dude! Thanks for going to the trouble of doing the photos, the writeup and a template. Great job.

So is the balazs still shipping with chain link swivels? I see you have a metal ball hook on it now

[aad03]

Yeah, it still comes with a chain link swivel; I just went ahead and put the ball hook on instead.

Cool, that's what I thought.

Looks fun. I'd love one of those but at $249 USD for the platform plus $1142.25 USD for postage I doubt I will ever get one here in New Zealand haha.
