Help please - first timer looking for the right tools

Postby shantybeater » 26 Jun 2012 21:18

Hi all,

For the first time i'm hoping to polish up my BBS LM outer lips, i have no experience of this but after reading through the recent DIY polishing thread on here i thought i'd give it a crack.

Can someone point me in the right direction on what tools to buy ? I've been looking at bench grinders which seem to come in different sizes & power outputs.

Is this suitable? are the mops/compounds correct? am i better getting a hand drill?

Any advice would be greatly appreciated...If it makes a difference they are all in a fairly good state although there are some light kerb marks on the outer lip

That bench grinder you posted looked good and came with everything, BUT it might be hard to do lips using a bench grinder because of the limited angles. Instead you can use just a regular like 4" grinder with the polishing wheels on it.

If you want to see my video on doing this here it is:

Good luck to you :)

Thanks for the reply :)

Its funny, I stumbled on your video last week (which by the way was the only decent one I could find). I'll go for an angle grinder instead (although i've already bid on a bench grinder!). A few questions if you don't mind:

- How about this grinder? http://www.toolstop.co.uk/sealey-sg115- ... 30v-p15742 - looks to be a 4" disc

- what level of sandpaper do you suggest I start on? two are in a similar state as your video so I will follow suit. The other two have recently been refurbed so have a hefty layer of clear laquer - but in theory underneath should be a mirror polished lip in good shape. Could i just run through compound on these?

- On the kerbed parts (pictured) how do I go about cutting back the metal? Is it a case of sanding it down? do i need to take it back evenly round the whole lip to keep things in uniform?

Haha thanks!

Now to answer your questions:

- Yup that grinder is perfectly suited for doing the lips. It's essentially the same thing I used. Also a heads up for when you're going to be using an angle grinder: the polishing wheels might need a little modification in order to fit over the shaft of the angle grinder (not a big deal) but just be aware of it.

- For the first two lips, the ones that are more severely damaged, start with 220 and then work your way up through 320, 420, 600, 800, 1000, 1500, and if you want to go the extra mile, 2000 grit. Keep in mind all of this is wet sanding. For the other lips even though they are in refurbed condition you're still going to want to create an even grain and consistency along the lip. So the sanding is still needed but it's just not going to take as long for the sanding when compared to the non-refurbed. So I would start with 320 and move up from there along the list.

- Yup you have the right idea. Just sand it down and take it back evenly around the whole lip just like you said.

I'm glad to answer any questions I can, so if you have any confusion just post up :thumbup:

Ok I got hold of a 4"/115mm angle grinder from my local store. There is no variable speed though. It's 620w, will this be ok? Should I be going for 4" mops or 6" to slow down the rpm? what size did you use rcdevil?

Plan on ordering either this kit:

or this for a 6" set:

http://www.ebay.co.uk/itm/290574566560? ... 1423.l2649

Are they both suitable mops/compounds? There appears to be no white compound in this set like in your video but I assume the blue is basically the same thing?

I've also just bought the following sandpaper:

Can you think of anything else I may need? I've got plenty of autosol, microfibers and plan on using something like collinite to wax the rims after, i also plan on sourcing some paint stripper from work, they use it on aircraft grade aluminium and the stuff looks pretty potent

Any update on the outcome?

I have the same wheels looking to do a refurb on the whole lip as I got oxidation and curb rash.

How did you deal with the curbings? Did you use filler and resprayed over them?
