Repainting the sides - grinder first?

[Iain_H]

Wow! Every time I come in here I get truly expert opinion covering the whole spectrum. Thank you! Just for info I have spent many a weekend a couple of years back with wet and dry. In fact it has become the annual "clean" while the flaking "reactive" paint comes off in stages from the paint below.

Wet and Dry has proved to be a lot of work so I was wishing to move to something better; well, quicker. the internet is full of applications and some have used grinders. I agree now that these are far too violent. I can't afford the planetary sander but that does appear to be better than a DA sander? Chemical strippers are too risky for me.

I decided to purchase a DA (150mm - 6", with 8mm orbit?) for its value and to first see how I go with this (£82 - Sealey). I'm just about to purchase hook and loop sanding discs and get plenty of them (starting with 80 grit).

Brilliant all. Cheers.

A random orbit sander also known as a D.A. (dual action) sander with coarse discs will remove paint better than anything else and without damaging the surface.

no it won't, as I have already said, a planetary sander will.

I've been looking for a planetary to hire for you but can't find one - they are pricey

One of the semi pro makes (de walt I think) used to make one that was switch able between planetary and random orbital, I can't find that either but if you see one that is the best possible tool for DIY - best of both worlds.

EDIT found it
http://www.toolbox.co.uk/makita-bo6...n=GoogleBase&gclid=CIKOsOK2hLkCFYfMtAod0XIAaA

5.5 mm orbit and switchable from random orbit to planetary. If you can afford it this is perfect. Top kit makita too last a lifetime of DIY.

Edit 2 bugger that's a 110V one.

EDIT 3 found a 240V one £246 inc vat

I went into Lawson HS to get advice about sanders, saying I wanted a powered orbit as we sand boats, if you're paying for the labour it is the most cost effective tool.
I had to wait for ages to speak to their power tool expert.
"We don't sell any" he said. "you need festool, we don't sell them anymore".
Well there we go they do sell them. The irony is you pay more in the shop. When you ask why they say "because you're using our expertise"..........

If you can't stretch to it the sealy with 8mm orbit will be a good choice for that price.

I must admit I've never tried a planetary sander.Are they good for the same kind of jobs as a random orbital sander?I might be tempted to get one.

Now stop being silly, I use one every day!

I pay people to use one every day. I pay less with a planetary because it's significantly quicker......
I have been known to pick it up myself too when working on my own boat.

the same but quicker, the only difference is in the one the head rotates of it's own accord, in the other it is powered round - the machine looks identical and the orbit bit is the same in both modes. Take a look at that makita because you can switch from planetary to standard random orbital so have the best of both worlds - I'll probably go and get a couple this week actually this thread has been useful for me!
