Thanks once again Art will have a look at Vulcan site

I am going to purchase a constant force spring 2.5kg cm

What is the calculation required to work out what weight this is equivalent to ?

Assuming it is related to the drum size the weight is wound on

Just trying to get a feeling of what I will be able to drive with this


Ian

still having fun  I think
added some simple arms

as you can see only get about 90 deg swing from each impulse !!

still think I need more power from each impulse

No sure which of options 1-5 to try first maybe a mixture of them all


Ian

Thanks for all that Art

Know you are busy with Webcam stuff so thanks for taking the time

Would like to get more spins per flick !
Are these possible solutions to this ?

1 increase the weight ( would rather not do, feel 2lbs is enough)
2 reduce number of teeth on chrono ratchet ( make the flick last longer )
3 ...

Found out why I got binding gears the width in circular gears is not remembered


eg set it to 0.48 go non-circular return to circular and it is set back to .5 !!
similarly width in non-circular is not remembered !

Also resets to .5 if exit program next time I run GT


A bright side this has shown ...

Thanks Art

Knew it was simply
Was tired and frustrated I had done just that on non circular gears duh!

Thanks Ian

i have just laser cut some circular spur wooden gears  2.5mm Mod and they bind a bit

Can solve the problem by bending the shaft a smidgen

Thought there was a way to add backlash but can't see it or remember
Using GT 2.29

Any tips or hints please

Thanks for the calculator on cage gears

in the latest version

Art

You always respond so fast 

thanks
