Metal detecter under D4 to detect screws

**PhilipA** · 16th February 2023, 10:11 AM

Its much worse on a motorcycle in inner Sydney roads.
I used to have about 4-5 tek screws in my rear tyre before they had done 12KK.
The tek screws drop out of tradie utes then are flicked to the centre of the lane by car tyres.
Harbour bridge seems worst.
Regards PhilipA

Why do you ride in the oil line? Stick to tyre lines, much safer

Edit: and looking at when these punctures occurred they're suspiciously regular - I think the psycho responsible for this has a reminder set in his calendar.

Have yiu checked where you work (if you are still working)?

Utube has a few videos on how to make a cat deterrent that sprays water based on a movement detector. One set up to operate from a bucket of water with some citronella oil ( or other of your choice) to perfume the water might be a subtle way of expressing your opinion on there activities

I've had a few punctures over the years from screws and even a house key once and the screws appear to be tradesmen drops from the back of the ute. I remember moons ago before the railway was built between the lanes up the Mitchell Freeway an incident where a courier left Osborne Park and drove down the freeway scattering screws everywhere and dozens of vehicles got punctures that night as they went over both the up and down lanes by going under the crash barriers.
Chaos reigned that night but I was one of the lucky few who got past without incident.

PS. I've also got cameras and red security lights up due to having a ***** of a neighbour and they've caught several intruders just coming down the driveway and when they come on they go back quick.

I don't drive to work - the car is often only driven on weekends - but when I do drive to work it's usually parked in a commercial car park.

I'll also invest in a TPMS.

I was going to reply earlier, but got busy.

You don't have Yokahama tyres fitted by chance, do you?

I had them on my D1 for a good few years, and simply got fed up with their attraction to screws and nails, I think mainly from, but not limited too, my driveway.
Worst tyre I've ever had in terms of 'durability'. they wore well(ie. tread depth) .. but Geezuz, were they weak as the proverbial bodily fluid!
I lost count, but in about 3 or 4 years and not al that many klms(maybe 60-ish K klms) I reckon I copped more than 20 deflation events.... all nails or screws.

I still live at the same place and have spent more time in the driveway with the recent lockdown periods ... and the new cheapo Chinesium 10 plys hadn't had any metallic intrusions until just a week or so ago.
Was a doozy too.. nice large headed roofing nail. Where from, no idea.
I've now been on the 10 plys longer than I was on the short lived Yokos' and I reckon my local tyre place may have gone out of business now!

For magnetic nail pickups devices ... nothing beats the good old junked speaker magnet magnetically attached to a steel stick! I used to do it all the time on the driveway and the shed, which also picks up the dusty flotsam after welding and grinding something. I used to just sweep it, but found it's too dusty and probably not good to be inhaling it as you clean it up.

Many years ago brother had a dead viscous fan in his car and we were camped on some thick(not tall, just very lush) grass. Of course we lost one of the nuts that hold the hub to the spindle, and trying to find it was high on impossible.
Builder brother in law, who informed us of the speaker magnet sweeper idea, used to do it all the time on his jobs after a day or so ... found the nut in a few seconds!
