.078 wire drive questions

[Chuck E Cheese]

i will start out with the basics. is a 1521 1.5d too much for .078 wire drive with a x646?
i also want to know how to set this up, what bearings do i use and where. i am using a speedmaster stinger strut. i think i understand but want to see someones set-up (hint, hint jeff wohlt).

1) how many bearings go in the stinger?
2) do i also put bearings in the stuffing tube? where and how many?
3) what size bearings do i need and where do i get them?

please post pictures.
i have 5mm to .078 couplers and wire drive and am itiching to use it in something. i am also building a rigger but i think the bend in the stuffing tube is going to be to much

thanks!!

Should be fine with that 078 system.

Two bearings in the stinger. 5/16OD x 3/16ID. Nothing in the stuffing tube. Get some hybrid Ceramic from boaca or get there abec 5 if they have them. Very smooth but expensive.

do you know the part number by chance? the only abec5 i can find if for skateboard wheels. they also ask the width... thanks

Jeff,
What struts on the market use a 3/16 x 5/16 bearings, like his speed master? See my other thread, as mine is now broke.
