Any handy grandads able to help?

Yes, great to see you back wobblybits

Sorry to see that you didn't get your ramp sorted Hooty

But hello Wobblybits

As other have said rubber is very difficult to plane down or sand. If it is a ramp, could you not shorten it from the thickest end, it would then be thinner.

If you have a jigsaw take an old blade and sharpen the cutting side to "Stanley" knife blade sharpness and try that.

Rubber is normally cut using a sharp blade in a bandsaw (no Teeth).

watch your fingers !

I have wrapped it back up and shoved it in a cobwebby corner of the garage. Ramp? What ramp!

Thanks for trying to help! Much appreciated. I like the idea of heating it up, I don't think it will be any good for this though it is too big - think big rubber doormat/scraper, but 1 metre wide and 4cm thick at thickest end)

A local handyman/woman (!) to take a look befire you get rid?

Yes lucky and that's why I asked!
Hardly inundated with suggestions from the males of the species but as usual, a few practical grans have tried to help.

If you have an electric drill you could make a series of holes which might make cutting easier.

Good advice, that. I've wasted many an hour, trying to modify things and failing!

Put it on Gumtree or Shpok and start again!

Would it be malleable if you immersed it in boiling water?
More to the point, would being malleable be a help to you?

Rubber is really tough, gillybob. Don't think I'd be able to do it with a knife, as there is too much to do and I will need it to be level. I had to use a jigsaw to cut the corner off, as it was much too hard going with a hacksaw. Thanks though!
That's what I was thinking re sander, but not sure what else to try. I wonder what an angle grinder does?!

Perhaps chalk it up to experience and hide it in a corner of the garage!

This is Grandads' shed!!

Hope you find a solution but may I just ask why your post was addressed to grandads?

How about slicing the rubber with a very sharp knife or using a sharp planer? Being very careful with fingers of course !! I think it depends on how hard/soft the rubber is and how much needs taking off.

I think a sander will just clog up with the rubber.
