Hi Guys

Yeah, a friend of a friend has offered to make the tables for me. I'm just finalising the dimensions I need before giving him the thumbs up.

I would like to stick with steel as I feel it would be stronger, and I'd prefer to have as much weight as possible. The sand idea is a great one although I still don't know if he would be able to do this before welding, and cannot see how he would add it afterwards as there would be no "openings".

Another thing he suggested was to use angled steel instead, something like: http://www.slhtrade.com/steel%20product ... %20Bar.gif This would make the footprint of the table smaller (great!) and not being hollow would eliminate any chances of problematic resonances. He feels quite sure if would be strong enough (especially with three lateral sections near the bottom). Confirmation on here would make me feel better about it though!

He has also offered to weld small plate sections to the feet, so that I can add height adjusting feet. That should prove really useful as the floor is not particularly even in my room!

Thanks guys

Max

angled steel could work

Id think 25x25x3 steel angle would be fine. The sand, if you went for box section, could be poured in, then a plastic end cap fitted, they're a tight fit, so would tap in.

Im not a big fan of angle, never looks nice imho, but it will work. The adjustable feet would be ideal, only need the adjuster on on foot really.

You would have a problem welding if you don't leave openings in the box sections to allow the heated and expanded air to escape from the insides.

You guys are so helpful. I really appreciate it. Cheers fellas.

So here's a plan.....

- I definitely want to go for some adjustable feet.
- He can weld the unit together leaving all the ends open without sealing anything and without filling it with anything. Hopefully no problems such as those pointed out by Stoday then.....
- Once finished, add some plate or something to the bottom for the adjustable feet to screw into (any ideas here guys?).
- Before adding the top and fill with sand. I'm not sure if I'll be able to get sand fully into the horizontals. But then again, if I fill bit by it and keep giving it a good shake - it might be ok.

Here's a sketch of what we're looking at, including a steel plate on the top. I guess the sand could either be done before the steel plate, or holes could be drilled into the steel plate and the sand added afterwards.



One last possibly stupid question folks. What type of sand?

Cheers

Max

The nearest metric equivalent to 16gauge is 1.5mm, 1.2 is the next thickness down....

You can get adjustable feet with end caps that just knock in to the box section, otherwise hed need to weld palte on then tap the holes or weld a nut on the back then weld the plate on.

How i'd make that, the sheet wouldn't be covering any open ends. IF he mitres the corners of the top frame, you could add the sand from one hole, perhaps drilled at the back. Or make the top frame, drill some holes at the corners where the legs join on, then fill through the open leg bottoms.

Sounds like a lot of messing about though..... How about just going for solid bar, material will cost more, could go for 20mm, but would save you a lot of messing about.....adjustable foot wouldn't be so easy, but as i say, in theory, you only need 1 adjuster, 3 legs will always sit without rocking.

as long as all points of contact are insulated then i cant see how much difference the sand will make... a lot of messing about for not alot. rubber adjustable feet on the end caps a rubber anti slip mat on the top

Dry.

Generally you can get two types, viz: soft sea sand and sharp river sand. You should use the soft sand, which will flow more easily. If you live near the sea, you could dig some up for nothing. Just need to sift the turds out wash the salt out and dry it.
