Need advice on flexy rod size (1 Viewer)

[Mike Khor]

About to build my first flexy rack and was wondering if anybody has done it with 1cm thick threaded rods instead of the usual 5/8" ones? Reason I'm asking is that I can't find anything bigger than that here (malaysia)

Thanks in advance.

Lets see there are 4047 square meters in an acre and 6 fathoms in a foot so that will make your flexy rod just under 1/2"(about .4) Will this be enough? Maybe. It will depend on size of rack, weight it will be holding, distance between shelves and number of rods used. If you are holding standard equip (No monster sized amps), keep your shelf spacing as short as possible. This will reduce flex in your flexy. keep the weight on the lower shelves and you should be O.K.

Thanks for your reply, Bill. Actually, my concern for the flexy's strength is because I intend to put my 29" Sony on top (not quite sure what the weight is). I wonder if it'll hold. The only other equipment will be a DVD player, CD player, VCR, and the receiver, for now that is.

Perhaps I should consider adding 2 more rods in the middle (of the TV) and space out the width of the shelf?

How high are you planning on making the top shelf?

I'd be very leary of its stability if you plan on going more than 18" high, no matter the spacing between.

1 cm rods sounds like it would be too thin.

If you hold the rod on either end, can you bend it much with your bare hands? If so, I'd say its a no no, even if you used 6 rods instead of 4.

I wouldn't want to see you TV come crashing down.

Just my 2cents (or should that be 2 ringgits?)

Well, I had intended to make a rack that's 24" high. You don't think using more rods would be stronger?
BTW, it's 2 sen over here, and no plural for ringgit

I don't have a conversion chart on me but assuming the above post is correct and 1cm is about .4in then that is too thin to support a 29" television. I've built a couple of heavy duty racks with 5/8 inch rods and they are strong enough to support my HT and aquarium. I built a rack with rods that were about .4in and I wouldn't trust it to hold anything heavier than my 17" cpu monitor.

Hmmm... sounds like you know what you're talking about, Carl. I guess I'd better not take the chance, HT stuff costs good money. I'm going to look at alternatives.

Thanks everyone.
