Having a small nub appear in the center of your bowl or platter during the sanding process
- A.
Is caused from excessive sanding
- B.
Can be avoided by initially making that area slightly concave to begin with
- C.
Can be removed by hand sanding
- D.
All of the above
Correct Answer
A. Is caused from excessive sandingExplanation
The small nub appearing in the center of the bowl or platter during the sanding process is caused from excessive sanding. When sanding a wooden bowl or platter, if too much pressure or sanding is applied to a specific area, it can result in a small nub forming in the center. This can be avoided by initially making that area slightly concave to begin with, which helps distribute the sanding pressure more evenly. However, if the nub does appear, it can be removed by hand sanding. Therefore, the correct answer is that the nub is caused from excessive sanding.Rate this question:

Sanding a bowl can be potentially dangerous if
- A.
You remove the toolrest before sanding
- B.
Wear dust protection mask or air-stream helmet
- C.
Wet the wood slightly while sanding to keep sawdust from flying around
- D.
None of the above
Correct Answer
D. None of the aboveExplanation
Always remove the toolrest—hands and fingers can easily get caught. Wood dust in your lungs is cumulative. It doesn’t hurt to wet the wood of your bowl, but only moisten it.Rate this question:
