Cheers! Actually I have reworked the design and it now takes fabricated parts. Took a lot of thinking! Yeah, I guess the books are the way to go. Keep well.
Hi everyone. I would like to build my own foundry, if possible to melt iron. From all the research that I have done, I can see that almost everyone opts to melt aluminum, even when it comes to building a metal lathe. The reason why I would like to melt iron/steel is that I am also wanting to...
Make a rocket..
Well, I have been toying with the idea of making a rocket for some time. How about using a CO2 cannister as your projectile? Fit fins, find a way to puncture accurately and test. :devil: Another option may be to simply put a fireworks rocket inside your pipe, aim & ignite. It...
Spraygun solution?
Hi all. Couldn't one possibly use the same principle as a spraygun, where you force an airstream past the mouth of the issuing tank and thus create a local area of low pressure? Of course, this pressure would have to be let off somewhere.
Another alternative may be to...
Useful contact?

Hi. Follow this link: http://www.aardvark.co.nz/pjet/spinning1.shtml . This guy actually builds pulse jet engines as a hobby and he seems quite handy. This particular link shows how he built a metal spinning lathe with which he turned venturi's. I am sure that you...
Hi. A mate of mine had a gemsquash (A type of pumpkin) blow up inside his microwave and now it won't work. I have heard that troubleshooting for microwaves is quite straightforward. Does anyone have advise on what to look for?
OK, I think we have a winner here... Coat hanger?! Hehe..
While it is not ideal, one could even build a generator using a normal DC engine/petrol engine and a car alternator to recharge your car batteries quickly. By the way, is an alternator DC or AC? And a generator?
I will build the...
Well, I don't know yet but will be sure to update you. It's been a few years since I've seen a textbook but the theory behind this whole concept is that with DC you can maintain a spark at a lower current because the current is not going through zero on every cycle. Lower current = lower...
Welder output connection
Boulder
Hi. Well, the way how I am going to do it is to build a separate box for the full wave rectifier with 2 buzz-box like input electrodes on the input and the same for the output of the rectifier. Then I simply make two short welder cables with eyelets on both...
Boulder
Hi. Yes, it has different electrodes that you can attach the live (stick) cable to. Do you think that will be sufficient output control? Also, what thickness is 14 gauge mild steel? We do not use that measurement here.
Many thanx
Knievel
Yeah, I hear you.

Hi. Thanx for your reply. I was actually wondering about the rods but the copper wire seems like a good idea. Now for the next problem: Flux/atmosphere control. Building a wire feed with gas supply will most certainly be complicated and expensive. I will have a quick...
Hi. I have an arc (Stick) welder with a 1200 Watt output. In South Africa we run 220v single phase electricity. The current should not be above 20 Amps.
In order to weld thinner materials (and maybe even aluminum :biggrin: ) than possible with an AC welder, I am attaching a Wheatstone...
