Dave's boss has a big fat wallet to pay for new teeth on the planer every week!

i couldn't imagine using your planer on a slab of PQ concrete. ???

We've used our Universal Bingham planer on concrete (to form a joint between tarmac and a concrete section when the planer was new - and 8 months down the line we are still on the original teeth!

[seanandruby]

so every job you've done in 8 months the planer was used on concrete? ??? if not what percentage was it used on concrete. not knocking, just inerested. i may have to stand corrected.

Oh god no, we once planed a concrete slab to accept a tarmac joint, plus it chews off the off concrete edger found on driveways etc. The pecks are still in A1 condition, not changed one yet.

99% of it's work is in tarmac.

Planers are not a piece of kit I;ve ever owned. they were hired-in as needed, but as I understood it, you could get different teeth for different surfaces. One set of teeeth for HRA, a slightly different set for macadam, and a really tough set for concrete.

I think I've mentioned previously that I was asked to arrange for an area of granite setts to be planed and Wirtgen told me it was possible but the machine would have to be fitted with a special set of teeth, and it was quite likely they would be knackered by the time the whole area was planed.
