## Questions & Answers

**Q: What is the offset of the blade tip to spindle center?**
A: For the 1/4" set up the offset is 0.150" and for the 1/8" set up the offset is 0.075".

**Q: Where is this made?**
A: I assemble them here in Oregon, but some of the components are from international sources.

**Q: Is there a spring inside the cutter, to assist in relieving the downward pressure on the spindle?**
A: There is not a spring inside this, it relies on the cutting surface being decked flat. I did try some spring mechanisms when prototyping, but the added complication didn't yield better results.

**Q: I dont know how i screwed this up but i got the 1/2" stem and need the 1/4" stem. is there a way i can convert this one?**
A: Is there an option for you to purchase a 1/2 inch collet for your machine?

I just spotted an adapter on Amazon 1/2 to 1/4 inch router bit extender. Check amazon
