When Istarted the build, I used needle files to remove the nibs from the brass bits. However, as time went by, parts got smaller and smaller, and also much more fragile and delicate. My files were just not upto the job. This gave me serious problems, as a lot of the parts will not go together correctly if a nib exists where it should not. I think I now have the solution, out of desperation, I tried the sanding disk on my Minicraft drill, this does the job perfectly even on the tinest and flimsiest bits. I t has some limitations as cannot get inside tight parts.  Note Minicaft= Dremel, to gived the same effect. Also, the drill was stopped while I took the photo for safety reasons. |

Novel way of doing it. I wouldn't be using this method as knowing my luck the sanding disk would probably 'bite' the piece Im sanding and destroy it.
As for the 'fiddly' bits I have a diamond dust coated file for use on these bits.

Hi swanrail, I also did the same, but I used a tool called a "Speed-matic" that is used for all types of fine work like engraving, etc. It came with small and very fine sand bits. All nibs on brass work were removed with excellent results.  |

Like Chill, I too use a diamond crusted file. I hold the parts in a pair of smooth jawed pliers if they're too small to hold by hand.
I'm not a lover of power tools for modelling. I find that they are generally too agressive and difficult to control. Maybe I'm just kack-handed, but each to their own.

I found that when I used the file system, the pressure on the file to make it work tended to bend the very fine etchings, especially the rail parts.
My method lets me gently apply the brass to the wheel with virtually no pressure. It does of course require that the piece to be denibbed is securely held - I use long nosed pliers tightly clamped!
My sanding disc is of fine grit, and in any case the pressure on it should be carefully adjusted so that it cannot bite! So far, after what seems to be hundreds of nibs on the latest etchings have had no problem but excellant results.

Hi Don I use both the dremel with a small grinding disk or a diamond encrusted nail file. The women in the house keep loosing theirs ...... ;D ;D  so I seem to have a endless supply .........  Usually I use my fingers to hold the bits, less rigid and less bending of fragile bits They all work well Baz |

I use my set of bending pliers to hold steady the bits for filing. Less likly hood of inprinting the delicate parts.
