Filing Cast Iron

I am not particularly a beginner but I thought I would ask this question here as it is likely something that every beginner should know.

I have turned a set of wheels for my 3½G Titfield Thunderbolt but I have casting flash between the spokes (of course). I have tried filing this out with swiss files but they clog almost immediately. Does anyone have any suggestion as to what would be the best tool to use for this job?

TIA

Dremel - or similar - with carbide burrs.

(Plus tight-fitting goggles as abraded cast-iron mini-granules get everywhere!)

Rub chalk on the file and use a file card to clean the file.

In my very humble opinion a much better way to clean a file is to use a piece of brass or a fine brass wire brush.

Baz The chalk is not to clean the file it's to stop clogging. Definitely a bit brass or copper for cleaning

What "Cut" is your file ? I use "O" cut for those sort of jobs.

For small areas of 'casting flash' I have found that diamond 'needle files' work better than conventional ones.

A few years ago, this would have seemed an extravagance; but the availability of [cheap & cheerful] sets from the likes of Aldi and Lidl has changed my approach.

Only really works for single cut files.

Thanks for the input. Learnt a bit! Never heard of putting chalk on a file to stop it clogging, Never have thought of using a Dremel and I hadn't heard of diamond needle files. I have just looked in Boyes and they have pack of 5 for £4 or thereabouts.

+1 for the Dremel approach. I also use a rough 2nd cut to get under the meat of the flashing then titivate up with Dremel & carbide bit.
