little bolt hobber refined edition

I've found it difficult to make bolts for standard wade (and collaborative wade) because they require hobs to be placed close to the end of the bolt.
I've redesigned the tool to be
-more flat so it allows inserting 55mm bolt other way round and securing it with locknut-equipped m8 nut
-with extra spacing to move the tool further toward bolt end

cons :
requires very flat m3 nut (i've grinded one down to make it just 2 threads wide) for the dremel tool . you could also increase indent of the extra spacing and use more standard dremel tool holder.
be carefull and do not use force - if nut its too thick it may damage thread of the dremel .

i've used 0.25mm jewellery grinding disk , but it's not really so perfect - it's not perfect flat . results are very good though, note that the bolt still retains it's hardened surface at the teeth (the black colour)
even though disc is not rated for 12.9 hardened steel it did not wear very much.

the zinc plated bolt was hobbed with 0.5mm disk - pics for comparison. I think it's also good enough.

edit : after making several bolts i've refined the design even more - reinforced where it was bendy, made the split base even more flat, tweaked main nut holes size (any slack is not really good).

Also using thinner gear does not make sense now - use regular one.

Tested bolts aswell. with 12.9 bolts, dimensions used are quite on the edge of material strength . i've cut few hobs to be double the width , while same deep (about 1mm) , so the metal 'stripe' pushing filament got half thin - and they bent under load.

bolts have much better grip than ones made with tapping tool.
Limit seems to be grinding of filament rather than slippage , after certain point about half of filament can be ground away very quickly :) i think only solution to that would be moving to larger bolt diameter to reach larger contact area or just using two bolts (check out collaborative wade or brute force wade)
