Caliper refurbishment - Is a Dremel up to it ?

[John-M 0]

I have a set of 288 calipers to install and they are in need of de-rusting etc.

 

Is the Dremel tool up to the job ? Or too small and underpowered ?

 

And what about the 10.8 V Li-Ion battery model ? Anyone used that ?? How does it compare to the mains models ?

I found my dremel was'nt up to the job and used wire wheels in a drill!

i use an angle grinder + cup shaped wire brush fitting + face/eye protection 8) and to finish off nice and smooth with a flap wheel in a drill.

got a bucket of water and a battery charger? then try the above links , doesnt hurt plating or rubber etc and works just as it says , will completley derust the parts after a quick scrub and rinse

That looks very interesting, thanks.

 

Also thanks to the other advice - I'm discounting the Dremel now.

 

I'll report on how the bucket of water and battery charger system works :)

i did mine with a dremel

 

 

 

Took ages, get loads of mess everywhere, but suprising how much rust/corrosion came off with the dremel, i had done them with a wire wheel and they looked ok but not very smooth.

 

i'd look at shotblasting if i did it again. Some of the home/portable kits are quite cheap or find a local company in the yellow pages

if you get a dremel get a corded one imo, you get full power all the time and don't really notice the lead

Im gonna do some wishbones soon...

 

Was thinking of either blasting them or at work we have a wire-brush wheel on a disc grinder-type stand...what d'ya reckon?

 

Was wondering when it comes to painting, do I paint before I put the bushes in? Sorry for thread-jacking John-M :grin:

I've got both mains and the Li-ion one and although it's very good you will need the mains powered version for something that intensive, 3corsameal's done a great job but like he said it will take ages!

 

I use Suffolk Stove Enamelers (just outside Woodenbridge) for sandblasting / powdercoating stuff and they are very good - not had calipers done though, only carriers but calipers should be fine as long as you tell them what to mask off (ie the piston bore and the threads) - I don't bother cleaning or painting hardly anything now, just give it to them!

works just like the sites say it does ...pretty amazing really

 

just be aware its line of sight only , so the parts will need turing , use hot water for better results and make sure theres a good strong contact on all the wires ....you will find the soda crystals near the washing powder at the supermarket , its under a pound for a large bag

 

after a few mins you should see it bubble ..if not re check the connections

 

then after a few hours or overnight if theyre bad , stiff brush and a good rinse /jet wash
