## Questions & Answers

**Q: What is the maximum diameter? The description says 18" while the video says 24"**
A: With the "extender leg" attached I am able to open the compass to a diameter of 11.5".  I don't see how you could expand it to 18" or 24".

**Q: Can you use this with other drawing utensils like markers?**
A: Yes you can use markers and pens and pencils. Built in there is a lead, but there's an attachment that lets you use any kind of writing pen/marker/pencil that is up to 1/2 in diameter.

**Q: What is the diameter of the lead? I need more than the standard black lead. Most compass's are 2mm>**
A: This is also 2mm.

Make one, there's plenty of cool compass plans available online. That's what I did for my trammel points (beam compass)

**Q: Does the small compass use the same 2 mm replacement leads?**
A: Yes
