now that the "Boom for the crane" is finish I need to install the Pulley my idea last night was to manufacture something similar to this
and then just install the Pulley at the end of the boom. but after xy9ine posting this morning i change into a "Hanging" tension structure, but not after spinned in my head a million times.
notice the two little pendular pieces to hold the pulley on a floating mode.
it looks something like this.
i think i need to make a sliding surface in between the two green pieces so the chain moves better , chain was on the smaller cogset but maybe on the bigger one is no big deal
this is how it looks when finish
now the pulley is a little forwad from the pivot axle but hopefully since basculate with the swing arm motions is not going to be a big deal.
I'm a little worry the cranks are going to feel like "Morse code" since the swingarm will be moving up and down and on his own turn also the "crane" on a similar radius (even if minimal since the crane is so short), maybe afecting the chain tension,, well will see.
a view from the front
and then a picture of my super dupper messy house, can you beleive i need to take all that crap out just to make this little thing, actually that is a great comparation to the amount of mental work thaat goes into figuring out something like this, i contemplate at least 15 diferent ways of doing it all of then with pro's and cons, pretty much like opening a whole box just to find one little washer ..
well i hope I inspire you guys and gals again to go and follow your own dreams and ideas.
