Cad Lever


totally steaming!!

Recommended Posts

Looks like CAD for CAD's sake to me... not much thought gone into it. Radius where your finger sits needs to be bigger to make it more usable and comfortable. I'd advise not making it a 'c' section as that would bend and flex like a biatch... Angles look wrong- the blade wouldn't sit right in respect to the bars. You could include a reach adjust screw.

Also, if this is going to be part of a project it's probably worth working out some leverage values and forces and running a bit of FEA on it... will create lots more pretty pictures to BS markers with (Y)

Totally agree. You need need to consider how something like that is going to be manufactured. For something that complex I cant imagine any cost effective traditional manufacturing techniques.

My suggestion would be take the exact geo from a Maggie or Deng blade and model something new-ish around that. Do some basic calcs and then see what results you get from subtle tweaks in length, moving the pivot etc.

What program are you using by the way?

yeah that is absolute wank to be honest

I would like to see you do any better.

Nobody is saying its "wank" There just generaly giving him pointers of what to do for next time!

I bet if they were buming it you would also.

I'm going to say its a good effort!

I know for a fact i couldn't use CAD to save my life..Maybe that is because i have never used it.

Either way it looks like it could be very complicated if you don't have the right instruction!

Just keep at it and you will eventualy come up with a perfect design.

i was joking btw! im sitting here making stuff on CAD with him lol..... bike frame on the way lol

dunno if you've seen the fresh products lever or the rb designs levers, but they're both way cool (old style maggie though). Have a butchers:
