How to make a round thing without a lathe (plus model making tips)

Step 7 Put filler on shape with profile and sandpaper

Stages 5 - 6
Maybe you already had a quick go at sanding down between each application. if not now is the time to start doing that. Start with coarse paper P80 or P100 go with the curve and don't worry too much as you know that the next application will fill all the scratches left by the grit on the paper. After the final application you will want to move first to about a P200 and then finally to a really fine paper. I used P600, but that was only because that was the finest I could get in my hardware / DIY store.

You might note the slight colour change from the photos as we go along, this is just my digital camera and the fact that the sun was going in and out. These pictures were taken at each stage so that you can see how much filler went on and how much the shape evolved at each stage.

Looks nearly done now (shape wise that is).
