I'd be interested in coming along, but I doubt I'll have anything to bring and run for a few years as I'm about to start work in London... unless of course there is a go-kart worthy track and I'll get it out of storage - I built to thing and have never found anywhere to run it!

Hi,
I have just stumbled across this; http://techtv.mit.edu/collections/ehs-videos/videos

They are instructional videos teaching MIT students how to use the machine shop. There are some great tips and tricks in there for people like me who have had no instruction. I didnt even know what a wheel ...

Cheers,
After looking at that video I went back to google and found my thinking was more along the lines of an 'air-arc cutter', which seems more do-able. Air-carbon-arc looks interesting, although doesn't seem to be used much. I can find carbon rods on ebay, but not much else.

Hey.
A couple of years ago I bought the cheapest arc welder I could find with a TIG attachment. It has served me well, but now I'd like a plasma cutter...

From what I've read, a plasma cutter basically involves striking an arc, then blasting an inert gas (or just air) at it to remove the molten ...

Its a little late, but I'd suggest sticking a 'we have moved' page on the /phpbb2/index.php page. I doubt I'm the only person to have given links to people, or bookmarked pages that no longer exist...

Hi,
I designed a kart a while ago, and have just got round to mounting the engine. [Refer to image] I planned to shield the 180 bend with something (possibly stainless or aluminium or both) to help keep the heat away from the driver and fuel, but having mounted it, I am unsure if this will be enough ...

If you have a regulator already, take it off the tank and chances are, it will look like the image I have attached.

The screwey bit on the left (i didnt mean nut, i know what i meant hehe) threads into the tank valve. The nozzle bit on the right is what you connect the hose to. The big round flow ...

I'm not sure of all the techy words, i generally just go into shops and say "i need one of these" or think "that looks roughly what I want, does it fit, yes, buy it"

Having made a large-ish lockwood in the UK I can help you a tiny bit. With regards to the propane tank end of your setup, you ...

hands, hammer, another parallel bar, its up to you. The simplest way is to use your hands and bend the sheet up a little, then slide it though a bit more, and bend it some more.

Essentially you are putting lots and lots of small bends in the sheet, rather than just 5.

Forming tubes is easy. Search for the 'hinote roller' its a work of simple genius. Using this idea I was able to form a 1.5m, 0.9mm sheet of stainless into a cone in a short time.

Mike - Thats what I do now. However I would still strongly advise against using frames, especially as to many the number 1 website rule is 'no to frames' :wink: Try <table>, or better still <div>

Mark & everyone else, sorry for hijacking the thread, there seem to be 2 in 1.

If you ever need any help with this sort of 'stuff' feel free to give me a shout. Website development isnt my main area anymore, but I have just finished a 4-year PHP/webdev contract, so I have a general idea http://www.pulse-jets.com/phpbb2/images/smiles/icon_lol.gif

If you would like I can PM ...

If you are changing the overall site, it would be really great if you could do away with the frames used around the site to separate the navigation from the main page. The easiest way would be to include it at the top of each page, a simple bit of PHP could be used to do that (<?php include ...

Clean your browser's cache and see if that gets the new image to display.

You could rename the image file, then change the reference to it in the template header, that would fix it for everyone... although you are probably the only one with the problem :lol:

Yes, you will always end up with a multiple of 9, all of which have the same symbol.

11 - 1+1 = 9
29 - 2+9 = 18
37 - 3+7 = 27
etc.

They will always 'home in' as increasing the original number by one for example, (i.e. 64 instead of 63), will increase the number you are taking away by 1 (6+4=10 ...
