Howdy,



Not a bike related post but the tools are the same. Can anyone recommend an engineering shop on Dublin southside – Sandyford area, that could drill two 12 mm holes and put a 45 degree bevel into a hard plastic? I could attack it with my Aldi cordless drill but I’ve only one shot at this and google is not being the most helpful. A bench drill, the correct bit and whatever is used to bevel a hole is all that is needed! A mate in the UK said he could do it in 60 seconds and that includes putting the drill bit in!



Any suggestions? thankyou :bikerie:

(Not sure if Ive asked this before, if I have apologies)



Read this a while back:



Bike Tyre Pressure Setting – 10% rule



MY manual recommends 32 PSI front solo. I run 36. I found this out by testing as follows:



Inflate tire to cold pressure.

Run the bike a minimum of 20 minutes.

Check hot pressure. It should increase 10%.

If its less you need less air.

If its more you need more air.



Do this in 2 lb increments.



I presume the pressure rise when hot comes from friction between the tyre and the road, and a degree of flexing of the carcass itself. Based on the above, it would look like you can gauge whether the tyre is working properly by the temp/pressure rise between cold and hot.



Does that ring true – could you use that to find out what pressures you should be running for your tyres, your own riding style and weight ?
