Unless of course you wish to use an external supercharger of course, but that's just overcomplicating things, you'd have to worry about oiling etc then too which just isn't worth it. Still, a 2 stroke radial would be kinda funky, I wonder if some sort of centrifugal compressor could be...

slight difference between a winch on a small RC vehicle and a 5 ton crane though isnt there?

The way I see it. The intent to kill does not originate within the implement. A sane person will not be handed a firearm and instinctively shoot a person. At the same time a person who is set on murdering somebody else isn't going to be swayed by whether or not firearms are available, if...

I'm normally more into electronics and software than machining, but reminds me of a classic quote: "Its not a bug, its a feature"

Something I saw on an RC forum. "Don't judge a build thread by its replies but its view count" If the views keep going up then there are clearly folk interested

it is aircooled, but that engine is typically mounted to the front of a plane and directly drives a propeller. It relies on the heavy airflow it gets from both the plane moving through the air and the propeller also forcing air back over the engine. Mounted into a tank it won't have a propeller...

This will certainly be an interesting project to watch, haven't found any other wankel engine projects myself.

Most of my knowledge in this field comes from watching people build up their 3d printers although the concepts are much the same. I am not lucky enough to own a manual mill or lathe let alone CNC and dont have a 3d printer either. From what I've seen though, its advised to keep a dedicated...

dunno how I missed that (probably to do with me using the specifically sized datatypes on microcontrollers and saving the plain short/int/long notation for windows and linux where an int is 32 bit not 16 as on arduino), switching to unsigned int or a long would alleviate that restriction.

well he is currently using floating point math which could be the source of the issue (oh there are plenty of "fun" rounding errors in floating point math, never use it to track money, some bank tried that once and found that suddenly there was a defecit somewhere which eventually ended up being...

A Bedford is a rare sight these days and I'm only just over the border from Befordshire (home to the town of Bedford and also Luton the location of both Vauxhall and Bedford Vehicles headquarters). There's a few Bedford Rascals around but those are just rebadges, have met these guys quite a few...

http://www.appaltree.net/aba/Safety.htm Seems pretty simply, no gloves and the safety shields on equipment are there for a reason (I have actually seen an angle grinder disc shatter although in this case the safety shield was fitted and nobody was harmed at all)

Perfectly legitimate reason, as far as I'm concerned I just like to use whatever I have to hand which will get the job done. Got various ARM, AVR and MSP430 devices in my collection along with 2 parallax propellers (donated to me, like them but they have their issues which to me make them a...

A basic stamp 2, didn't realise they were still around. Still, whatever gets the job done. EDIT, woah those are not cheap, then again, its parallax, parallax don't know the definition of cheap even while being beaten over the head with a dictionary opened to the correct page. Rather than...

If you ever switch to ABS, run it in a well ventilated room, the fumes are nasty and we aren't talking "oh no you might get cancer from repeat exposure" (although there is supposedly that risk with ABS, PLA and nylon filaments too), we're talking I know a few guys that ever since being in the...

Windows 8 makes no difference to whether photobucket works or not... Personally in my experience its never worked anyway, whenever I've needed to share a photo online I've either used that forums native attachment system or imgur From windows 8 using google chrome I've already posted a...

many PIC ICSP programmers can actually take a firmware dump from an already programmed chip. This would serve as a way back to the original firmware. Dump existing firmware, reflash new firmware, don't like it, reflash to dumped firmware

Many full size production engines going into cars used to use wasted spark setups anyway. Really not a huge issue. I think its a bigger issue whether or not it fires during combustion than whether it also fires during exhaust.

Interesting discussion, hopefully I can take some info away from that for my "eventual" engine build.

That's the method I've seen recommended before. Video demonstration: https://www.youtube.com/watch?v=nvvKu56nHDw
