Hi,
After following through on my plan to level off the top of a column (see thread //www.diynot.com/diy/threads/tidy-up-level-off-outside-column.414789/) I've arrived at the point where:
I sanded it as much as I could - this did have some effect.
I put loads of car body filler gloop into the depressions.
I sanded again... quite a lot.
I was quite pleased with the intermediate result - it's a lot more level than it was before, there are hardly any depressions left, but there are one or two ridges remaining where the sander seemed to have little to no impact. This means the top of the column is not level, although it certainly appears a lot neater than before!
So, I went down to Screwfix and I bought myself an angle grinder - the Makita GA4530 - and some stone grinding discs.
Now, before I went out to buy this, I did an Internet search for "angle grind sand concrete" and found a few interesting threads and some YouTube videos...
...in one of those videos a guy is basically using an angle grinder to sand a concrete garage floor... he's just whizzing the angle grinder around and the knobbly bits of the floor are disappearing.
Yes, I thought, this is what I want!
However, my Makita GA4530 certainly does not seem to offer this facility.
When I connect everything up and put the disc on, the metal centre holder protrudes out of the bottom - it's about 5mm lower than the underside of the disk - so it seems that I must use it at an angle.
Likewise the guard of the angle grinder is about 10mm lower than the bottom of the disc, so there'd be no way that I could do what the guy in the video was doing.
Am I missing something?
Is there a way that I can use my angle grinder as a sander, but on the level - like, at an angle of 0 degrees, rather than the 15 degrees the manual says?
Can you buy a special disc that enables any angle grinder to become a sander that you can operate level / flat?
I could remove the guard, but that doesn't seem sensible!?! But I'd still be left with a disc that is higher from the surface than the centre holder is.
Or should I not even be thinking about this as this is not what I'm supposed to be doing with this tool?
Please bear in mind it's the first angle grinder I've bought so, no, I certainly don't know what I'm doing - but I do have a dust mask and eye goggles for when I give this a shot tomorrow!
Guidance welcome.
