| Post subject: | Gas struts in the boot |
I've done a search and haven't found any mention of anyone who has done a boot mod to fit gas struts and to get rid of the bootlid cables and stop the BANG, BANG when you accidently let go of the boot lid (I'm sure everyone has done this at some point  )
Do the Rover Minis come with them? - they seem to have everything else  Has anyone done this with aftermarket or an OEM-type item from another car?

Rover minis still have cables. |

I'm working on it, I'm sure it can be done. Not on the to do list for a while yet though. |

Replace or double up the stays with a piece of "hat elastic" 
Comes in black, is cheap, light, & easy to fit. One packet will give enough to replace it every few years too. |

I seen a pic of struts in a boot not long ago....will try and find it as I am sure there was something about a howto guide..... |

wouldnt the fact that the boot opens down be an issue with gas struts? they are exceptionally strong for lifting bonnets up.. they would rocket a boot down harder then you could ever drop it! |

I guess that would happen if they weren't sized correctly (ie too big). All the struts do is extend at a specific rate when they are not "locked down" so it wouldn't matter if a door/opening opened up, down or sideways as long as they are sized matched. (ie small in the case of the Mini boot) |

To retain any strength in the set up, the geometry is a long way from ideal |

What you need is a short strut with the gas let out, then it will only act as a damper. And if you have the seal at the bottom the damping will increase near the limit of extension, and do little to nothing when you are closing the boot. The guy who rebiulds struts for us says you can remove the gas with a fine drill, have the fat end up and drill 10-20 mm from the end, tape around it to keep dust out and theres a damper

I wouldn't recommend drilling into a gas strut. Doesn't sound clever to me.

I would
Just tried the theory using a 1mm drill, i drilled it so the hole didn't face me and held up a rag just in case, big non event really, little hiss and some foamy oil, i think removing a tyre valve would be more dangerous 
After drilling it i compressed it then while extending it i squirted in some crc, the damping gets stronger in the last 10mm, maybe some jack oil or singer oil would be better for stronger damping. All i need is to do another and get 4 of the little ball bolts and i will fit it on mine
Edit: Just drilled another, so i videoed the drama on my crappy mobile, it will be on here a bit later tonight for anyone interested. |

Heres my crappy video showing that you can drill a strut. This one didn't spit any oil, i kept it upright longer than the first. After drilling it i compressed it, submersed the hole in trans fluid then extended it to draw in some oil, you can see the damping effect. Easy, thanks for the idea Mearcat

That's awesome!
Even if the strut still had some gas in it, if it was weaker than the weight of the lid then the lid would drop down slower. |

That was a weak strut, a good push with one hand could compress it so i'm guessing about 10kg exdending force, it used to be pushing up a commodore boot. Problem : if it is inside the boot of a mini it will push the lid open, hence the need to de-gas it, a bit of vacuum might work. |
