GRRRRR! Broken bolt on my RC300.

A small round headed dremmel bit is good for starting difficult holes

Can you Tig weld a L shape piece of rod to it? then use it as a lever.That always works for me. Good luck.

Having just gotten some (6!) small M4 screws out of an XTR cassette with no damage to the alloy cassette carrier this should pose no real problem for someone with a steady hand and reasonable skill.

Well I guess I don't rate my own black and decker abilities of getting a sheared, uneven sub-flush steel fixing out of my favourite and coincidently very rare, soft as cheese aluminium frame.

As such The frame was finally stripped down last weekend, the stud has been drilled out on the mill and the hole (which it turns out is helicoiled at the factory by Pace) was re helicoiled.

Now I just need time to rebuild!

And would I have trusted any one else to remove it with a black and decker approach...no, no I wouldn't.

Grand... well done

The right way, is more often thean not, the best way (or vice versa or something)

Easy to drill if you have the skill. I do it all the time, last week I drilled out 2x m2.5 sheared bolts from middle burn rs1 cranks and retained the original threads. M5 a walk in the park! I always use a handheld dewalt cordless as far more accurate than trying to set something up level.

You got lucky.

I had exactly the same problem so took it to my dad who was a light engineer by trade and still has a home workshop full of lathes and mills.

He drilled my RS3 bolts out but the locktite or equivalent was so vicious it left the remains of the thread behind.

He ended up overdrilling the holes, plugging them, and then redrilling the original hole.

By chance I have a spare RC300 frame, so as one is stripped, so shall the other be built.

Only Rob could write this.

Hope this all works out pal

Guy has a milling machine and people with home workshops are making other suggestions...

Gotta love this place.

This made me chuckle too.....but hey, having a few stiff drinks before tackling complex intricate problems with only duct-tape, rusty chewed up screwdrivers and a lump hammer to hand in a badly lit damp garden shed can be very rewarding.

I have successfully used a Dremel type device to cut a slot in many rounded or snapped bolts, so a flat head screwdriver can be used to unscrew the offending part. The cut off discs are especially useful when worn down quite a lot as they are very small and can be used on very small bolts.
