Clarification of parts required

Hello all.

I'm sourcing the parts for a prusa Mendel build , inc Wades extruder

trying to check
[reprap.org] BOM

against
[reprap.org] BOM

[reprap.org] BOM
says
'Note that additional parts are required for the extruder, although some extruder parts are included in the table below.'



So.. which parts in the [reprap.org] BOM
are not in the [reprap.org] BOM ??


as one example: do I need 5 in total 608 bearing, skateboard bearings
3 from [reprap.org]
and 2 from [reprap.org] BOM

to add to the confusion
[ultimachine.com]
says 3 skateboard bearings for the extruder (different number to
[reprap.org] BOM)

To restate the quesiton:
Whats the overlap / duplication (if any) between:

[reprap.org] BOM
and
[reprap.org] BOM


Thanks in advance.

Mike



Update: OK think I've sorted this, ordered the printed parts from Nophead & the h/w from the reprapkitstore

with a bit of cross referencing , I think the two kits will cover off whats need for the extruder

The Wade's extruder BOM and Prusa BOM do not overlap other than the motor, I think.

There are 3 608 bearings in the extruder BOM (listed as two for the feeder and one for the idler). The Prusa uses three more (one on X and 2 on Y), so 6 in total.
