ALVIN drawing compasses span a massive range of sizes, applications, and uses. Our traditional beginner and intermediate level compasses are sure to find themselves right at home in any geometry or art class. Our professional-level compasses are the perfect precision tool that any engineer, draftsman, or professor needs to add to their collection of drawing instruments. These metal drafting compasses can make precision circles from 1/8" up to 22" in diameter with added beam bar.

ALVIN compasses are made with German precision engineering that allows for the precise and consistent drawing of radii. Made from quality materials such as zinc alloy, ALVIN drafting compasses are sure to last the test of time. The more advanced models, such as the 205V and the 975K, have adjustable knee joints for rapid adjustment and even greater ability to draft with accuracy. Kits with pencil adaptors allow for the attachment of a drafting pencil, pen, or marker. Add one of ALVIN's model 958 spring blade pencils to your kit with a pencil adaptor, or buy the model 505V kit to take your drafting abilities to another level. This pen is finely honed to create precise lines with India Ink.

Quality is meh. I was hoping for better especially for the price. However, it gets the job done. At small sizes the tips do not line up. You have to kinda push or twist it and then not put pressure on it or they misalign again.

I had a hard time getting this to hold a radius. The legs pivot out as the center wheel is too loose. Without even using it to draw, you can watch it creep open on its own. Look for a Staedtler instead. A little more, but rock solid.

Quality is fine. I purchased for sculpting. Serves it's purpose.

I teach math to children from kinder to 12th grade at LAMC, Los Angeles Math Circle, a free Sunday math school run by UCLA Math. Dept. I also give quite a few private classes based on the curriculum I have developed for the Circle. Geometry is an important part of my classes as the part of Math taught most poorly in the US schools. Compass-and-ruler constructions form the bedrock of geometry, so I teach them a lot. This way, I have an extensive experience with various compasses. Out of the compasses I have tried so far, the one under review is my favorite. It has no plastic parts - these always break down rather sooner than later. It's large and sturdy which is very important for younger children. The only reason I give it four stars are the tiny nut heads at the sides of the horizontal bar. Kids are very quick to turn them off, then off they fall, and they are very hard to find because of the tiny size. I advice parents to fix the problem with Super Glue as soon as they get the compass. Once the problem is fixed, the compass becomes a perfect instrument. I wonder why they don't just weld them in at the factory?
