There is a plethora of options for sanding tools besides the standard sand paper that comes with most models.
I did some research and compiled a long list of sanding tools that are used by crafters in the miniature world. Be aware that some of these would be overkill for Robotime kit models as some are geared more towards crafters who make things from scratch including cutting the wood themselves.
Personally, I started with the standard sand paper, then tried a longer wooden sanding block, then miniature hard foam sanding blocks which I found a lot more comfortable. They come in different grades. I also have mini files of different shaped blades which were very handy for tight corners or unusually shaped edges.
I have some arthritis in my left thumb joints, so I needed to look at something where I could hold the object being sanded stationary in my left while my right hand did the job for me with very little effort as it is the back and forth of sanding that puts the pressure on my left thumb aggravating the joints.
The game changer for me was my USB rechargable mini engraver. It has plenty of tool heads that slot in place and I use it on EVERY model. It is rare i pick up a normal sanding tool like my old ones anymore, unless I am wanting to sand the entire length of the edge of a long piece, in which case, I prefer my foam sanding blocks. The engraver is very comfortable to hold and run along the edges, and you can also hold it like a pen if you want to try your hand at engraving details.
So as mentioned earlier, below is the long long…long list of sanding tools that miniature crafters around the world have been known to use. Do you have a game changer in your arsenal of sanding tools?
