Review: This is a great drafting kit for starters - This is a great drafting kit for starters. I love the steel material because it lasts a long time and doesn't get dents on it like plastic rulers. The old school ones used to be steel on both sides and it would leave a metallic residue on the paper or just flat out tear it up. these have a cork-type material on the bottom that glides on paper effortlessly and don't leave a mark, so it works great. They might not be enough for the professional drafter because they are small in size, but if you are using a standard letter-size drafting notebook, they are more than enough. The ruler has both metric and imperial markings on it which is nice. The triangles only have imperial measurements on one side. It'd have been nice to follow the same pattern and include metric on them, but not a big deal. They also all have hang holes for easy storage. All in all they are good value for what they are and every bit perform as described. Review: High Quality! Recommended! - Pros: * Stainless steel, beautifully finished. * Thick enough not to easily bend, while being light enough. * Corners on the triangles are not sharp, and are slightly rounded. Great for school as it reduces chances of accidental injuries. * Cork backing is excellent quality, thin enough to keep the equipment nearly flush to the medium being drawn on, but thick enough to afford scratch protection to the media being drawn on, and also extend some slide prevention (depends on the media) * Markings appear to be etched and printed, not just surface printed. This will ensure that they will last a long time Caution: * Not a very compact size, so it won't fit as a replacement to the plastic ones in typical school kits. Great for higher school grades, and advanced studies. May be too large for younger students. Recommended with caution on the limitations! Make sure the size is acceptable to you before you buy (just look at the printed length in inches on all pieces) Thumbs up for quality!! ## Features - BUILT TO LAST - Made from heavy-duty stainless steel with cork backing, this protractor and compass set with beveled edges won't bend or warp with daily use.

Just draw a straight line (to the length you need) using a ruler or any straight edge. Next determine where you want your angle to begin. Your protractor has a small hole at the center of the flat side - set this hole at the place you want the angle to begin and align the outer ends of the protractor (zero and 180 degree) with your reference line. Make a mark (pen or pencil) at the center hole. If you go straight up from there you will see the 90 degree indication, make a second mark at that position. Next draw a straight line (with a ruler or the flat side of the protractor) from the center hole mark on your reference line up to the 90 degree indication. You now have a line exactly 90 degrees to your reference line. Need a 45 degree angle to the right...again determine your starting point (along your reference line) and mark it, then lay the protractor so the center hole is directly over that mark and the straight edge of the protractor is parallel to your reference line. Count 45 degrees up from the 180 degree position (or down from the 90 degree position) and mark the 45 degree position. Now draw a straight line from your starting point to the 45 degree position and you have a line to the right at 45 degrees from your baseline. The trick is to always use the center hole as a starting point (where the angle you need intersects your baseline (reference line), and you can't go wrong. Cheers. **Q: Does anyone know the thickness of these pieces...? Do they have a cork backing..?** A: The metal is about a 1/32" thick. They do have a cork baking and with that added they are 1/16". They are very strong you have to bend them pretty hard to get any flex in the pieces. **Q: Where is this set made? Thanks** A: Made in China **Q: Trae escala en cms** A: Solo la regla los cartabones son en pulgadas ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a great drafting kit for starters *by R***A on June 16, 2016* This is a great drafting kit for starters.
