first this is kind of strange, I'm sure I start this same tread about four hours ago,, now i can not find it anywere...
anyway here is my question...?
after looking and hearing the great benefits about the Balfa BB7's idler pulley design
and the more recent Appalache encarnation
i was wondering if a similar concept will bring any kind of benefits to the already great Nicolai M-Pire.
anyway that question was kind of valid and important four hours ago when i made the posting for the first time,, actuallly after i few minutes of finishing the posting i keep thinking,,well I don't have a place to go or a girlfriend to visit so lets play a little and see what happend.
I drop the bike from the rack and I study the diferent options for a second or two, also since i have very little equipment at home i decide to make a very simple working prototype out of My favorite material Delrin plastic.
since the E-13 guide and the main pivot point are almost on the same axis I decide to use the upper arm of the guide as the mount for the Pulley..
Ummm... DW is going to be Mad...
first i look into my scrap box and I found this piece that kind of fit what i need.
I will use this old blue bullseye
pulley
also since i need a very rigid back plate I decide to use two sets of SPD cleat mounts as oppose to the nylon nuts to improve on stifness and also instalation (much easier to hold)
since i don't really have the proper tools, i used a variaty of Holesaws with diferent diameters to comform the pocket require for the pulley and the chain to be house in.
the delrin Piece is about 10mm thick and i need to make a poket of about 7mm at the deepest for the chain and about 6mm for the pulley
after i remove all the material I possibly can ussing the diferent holesaws, i use a "Diamont wire" mount in on a hack-saw to make a few paralel cuts to the surface and carve the rest of the material, what apain...!!
by now I spend about two maybe 2 1/2 hours making this little piece, is for sure a pain when you don't have the proper tools, but for sure that little impediment is not going to stop me, at least after some time i got a little easier because now i can use the famous "two spinning drills" technic
the second chapter will come in a minute after i make sure i can load this whole tread...
see you guys soon
