## Questions & Answers

**Q: How good is this tool for bevel cuts ?**
A: I have never personally had to make a bevel cut but this tool could measure any type of angle.  If you do woodworking, this tool will definitely come in handy for crown molding and other situations where you have to figure out an angle to get a tight precision fit.  I am glad I own this tool as it has helped me many times.

**Q: Is this laser etched now or still has the sticker? Accuracy problem with sticker fixed now?**
A: I just received one purchased in 11/2014 and although it says "laser etched" it looks more like a sticker to me.  In any event, mine has the 'mismatched scales' problem others have reported. The package did not appear to have been opened before I received it but it may well have been, or perhaps someone received it before I did and checked right through the packaging before opening it to observe the issue. Mine is off about 1/2 degree which doesn't sound like much but it actually makes a difference on larger moldings and casings. I am contacting Starrett for help - I think that's better than just doing a replacement with the seller since if everyone starts doing this we will pass the bad ones around for years.

**Q: Starrett company representative, please confirm: "New upgraded design includes LASER ENGRAVED DIAL for EXCEPTIONAL ACCURACY"**
A: There now seem to be at least two different-looking versions of this tool with the same model number available online (both Amazon and elsewhere) and ranging in price from $50 to over $100. For example the video on the Amazon page does the demo with a different tool (about $50) than the one shown above for $100. Which version is the newest most "upgraded" version, and which ones have been sitting in a warehouse? For $100 and claimed to be "upgraded" and engraved, I expect an accurate one first try, no returns or return postage or delays - or I might as well just buy the plastic version.

**Q: I'm not empressed with Your cp#505a REVIEWS concerning it,s ACCERICY HAVE YOU MADE ANY IMPROVMENTS?**
A: I'm not sure what you're asking.  I bought this, found it defective, got a replacement, found it also defective, and gave up.  I haven't looked at another since.  Perhaps they are better now, I don't know.  I now use the old fashioned (that means good) Starrett Builders Tool No. 439-24.  It is excellent and lives up to the Starrett brand.  Hope that helps.
