Limitations

1. Motor Power

The 1/3 to 1/2 HP motor is adequate for light hobby work but will struggle with thick or hard material.

2. Build Quality

The BS-100 has an aluminum frame and table, which is lighter and less rigid than cast iron. This can cause more vibration and less accurate cuts.

3. Capacity

The 8 to 9 inch throat and 3 to 4 inch resaw capacity limit the size of stock you can cut.

4. Parts Availability

Parts may be harder to find than for larger Delta saws. Some parts may be discontinued.
