Before I start to buy parts and build my feather id like some viewpoints on the design and any flaws. There is a picture on my profile of the design.
Spec-
chassis and side skirts from 2mm steel
front and rear wedge from 4mm steel
powered by 4 of 18v challenge drill motors
2 30amp electronize speedos
Sounds all great. Only thing I can think of is changing the 2mm steel skirts to 4ish mm aluminium which might be just about the same weight but plenty tougher.
not sure wether i can afford ali at the moment but ill try to get some
Sounds good! Other than the shape and motors its pretty much like what mine is gonna be like. Have you made any test builds yet? I found I could chop about 10cm off my wooden prototype.
Good luck with the build.
Ok what do you reckon i should prototype with?
Ive used both cardox and woodox. :)
Lol AJ. Mark, if you design every last bolt to the nearest mm (even the simplest 2D CAD programs such as visio are plenty sufficiant) then there shouldnt really be a need for a prototype, so you can possibly save both time & money.
I will always stand by the crayon and napkin method :)
Mark, theres no need to prototype...Just think it through, draw it out (yes, good old fashoned pencil and paper) and then build it!
Thats how our machines get built. (Sometime we dont even go through the pencil and paper stage! Straight from a sick twisted mind to reality in one hit!!)
Unless youre overlooking some fairly important bit of physics during the welding of your frame and you need this little lovely and good-hearted woman to point out to you and your companion that the frame is twisted and under tension.
They did not believe me until they sawed through one of the beams. The resulting TWANG was music to my ears.
