I've been working on a project recently that involves removing existing details from a locomotive shell as well as filling in some areas with putty and sanding them smooth. The areas that I need to sand are surrounded with other details that I want to retain so I've been looking around online at some different retailers like MicroMart for small sanding pads that would fit the tight spaces...but with no luck. The project had come to a halt since I couldn't figure out a way to sand these areas. :mad: Here's a picture of one of the tight spots that needs attention, those gouges in the plastic are from my previous attempts at smoothing the putty:

I decided to see if I could make something on my own that would work. I seriously doubt that what I came up with is an original idea in any way whatsoever, but if it works for someone else as well as it's worked out for me I'll be happy.

For the handle I used some leftover Plastruct 3.2mm X 4.8mm rod that I cut about 6" long, but I think any thickness would work well as long as it's stiff enough. I cut a 45 degree angle on one end of the handle and attached a small square of 0.040" styrene sheet on the end. Once the styrene pad is attached I cut it to a size that fits the needed area. I have a few of the Testor's sandpaper packs that includes different grits. I cut a few squares of the needed grit and used a drop of CA spread evenly on the pad to attach the sandpaper square.

The little squares of sandpaper become fouled pretty quickly, but I just put another drop of CA on and apply another sandpaper square on top of the used one. Lather, rinse, repeat until the area is sanded to your liking. I figure these cost about $0.02-$0.03 each.

Here's an action shot - LOL!!

Here's the same area pictured above after sanding. Obviously I need to apply another coat of putty and sand again, but you can see how none of the surrounding details were affected (much :innocent:) by the sanding.

Like I said, I doubt this is a new idea, but I hope someone else can use it too.

Very smart move there!! Now you need to attach a small vibrator of some kind to it and you will have a heck of a tool!!

I've been glueing sandpaper to popsicle sticks, tongue suppressors and bits of scraps for more years that I care to count.

But, I never came up with a mini-sander as nice as that one. LOL

Nice job Bob and a great idea. At the risk of hijacking the thread, what kind of putty do you use. You do a lot of this type work and it always looks fantastic in the end.

wonder if an el cheapo toothbrush will work. I have a few used ones here. Let see if I can get the head apart and usable :)

I cut a fingernail (emery) board in half lengthwise to see if I could use it in tight places but haven't tried to use it yet - if it works I'll report back.
Edit: I like the handled version as it keeps the sandpaper where you need it and you don't have to worry about fouling other areas. Smart!

Nice idea! Thank you! The trouble with a finger nail board is that you have to bend it to clear surrounding detail work and it's really tricky. It doesn't take much of a "oops" to turn a great car into a piece for the spare parts box. I think this idea is brilliant because the stick is clear of those surrounding details.

yep, I tried using an emery board to clean up some flash and it seemed to loose a lot of its 'sand'. Not real happy with the results.
FWIW

Thank you sir! I use squadron green putty. It's cheap and the tube I have has lasted for years - yet another benefit of n-scale! :D

Same here, I tried using emery boards too. I cut one end down and bent it a million different ways and I was still hitting the surrounding details. With an emery board I found I was also limited to larger grits. With the handle I found that I have a lot more control over the amount of pressure and it keeps the sandpaper flat too. It's actually a lot like shaving believe it or not - haha!
