## 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

### ⭐⭐⭐⭐⭐ Review
*by J***R on 20 October 2025*

I used this in my woodshop to layout circles up to 8 inch radius. This required the extension bar that is included with the kit. It worked well, both on smaller circles and those requiring the extension. This was not an ultra-high precision application though, as I was laying out lines to guide carving. The tools in the kit are of decent quality, especially for the price. I am confident they will hold up over casual use. I don't know about using them for true precision drafting, as the mounting system for the extension and the pencil lead do not seem like they could be counted on the assemble the same way each time to sub-millimeter accuracy. But overall, the kit is fine for general woodworking.
