    Default Which polishing machine?

    The past couple of years I used a "vibrating" 20 quid polisher. Last year, the sound indicated that this machine is terminal.

    I have decided to go for a proper (like a grinder) machine. Can somebody please advise what power is needed and which rpm the machine should have?
    The boat is 23ft GRP. Anything else to watch out for?

    Many thanks in advance!

    As you're in Holland you could look at the Ferm polishing machine. Variable speed 0-3000 rpm, 1400 watts. About 60 euros from Gamma or less on-line http://www.ferm-gereedschap.nl/ferm_poetsmachine.

    Whether it would last longer than your 20 quid one is unknown.

    I know the International polishing products have a recommended speed in the instructions.

    Unless you are very experienced, it is generally recommended to avoid rotary (grinder) type machines as you can easily burn the paint/gelcoat.

    The answer is to us a "dual action" machine which has an action more like an orbital sander. One of the best value for money ones used on the car valeting scene is the Kestrel DAS-6 at which if you shop around you can get for around 85

    Light travels faster than sound, which is why some people appear bright until they speak.

    I am thinking of taking a look at the Silverline one Force4 have to offer.

    http://www.force4.co.uk/5584/Silverl...er-Sander.html
    The same or similar can be found cheaper though by shopping around

    or this slightly more expensive Clarke one from Machine mart

    http://www.machinemart.co.uk/shop/pr...-polisher-230v


    Easy of course to pay 200 or more for a professional machine BUT weight is an important consideration!


    Alternatives are http://www.machinemart.co.uk/shop/pr...-polisher-230v . . or . . http://www.force4.co.uk/1329/Force-4-240V-Polisher.html
    . . . . .

    Personally I want one that can be fitted with a foam compounding mop, so that the traditional paste compounds, can be used as well as with a bonnet for buffing a wax polish.

    I think at 1200/1300 watts the first two will be powerfull enough. I doubt if the other twowill be

    Many thanks!
    The one in the bottom right picture that VicS has embedded in his post is the one I have been using the last 5 years. Not bad but the bearings are gone so I need a new machine.
    The warning for the burning of the gelcoat worries me. How big is this risk? Does it depend on the rpm and / or pressure applied? I dont want to damage my boat...
    Is there a guideline which speed is safe to use?

    I've got the Silverline. It works great for me, and I'm not a pro. Just be conservative about speeds until you are confident, and ghe gelcoat will be fine. Try not to follow my example of dangling the extension lead socket in the water. Tends to trip the electricity..............if you are lucky.....

    Mine cost 50 from Boatsheen. They have some really good products too.

    We have a very large Gamma store near us and I have certainly seen them in there. However, I don't recall seeing the mops and accessories, so you may have to resort to the internet, or maybe an auto supplies store.

    The tophat ones are useless. The Silverline type is fine; it is a bit heavy so I wouldnt care to use it on 40ft+.
    The main use is for the "abrasive" part of polishing/waxing, as thats the bit thats hard manual work. Pesonally I find a liquid wax is quicker to put on and take off by hand.
