  • Protractor Review

    Alistair and several other friends asked me for a review of the Chinese copy of the Russian "Semionov Universal Vernier Protractor" that I bought last month, based on positive comments from Forrest and John. Guy Lutard sells a similar protractor.

    I bought mine for $17.50 from "nonstop-bid" on Ebay with $9.50 shipping from Shanghai, China:

    Here's what I received:





    Overall, the quality is surprisingly good, especially considering the price. The integral square is ground flat and square, and the rack and pinion mechanism operates smoothly.

    Like most Chinese tools, it needs some tweaking and polishing. The beam clamps are a bit hokey, but it looks like with some lapping, and replacing the screws, they'll be OK.

    The biggest issue (on mine, anyway) is that the clamp screw for the triangular gib for the protractor arc was drilled in the wrong place, so they bent the screw until it fit. This screw should be 90° with the protractor beam:



    I'm probably going to TIG the screw hole closed and re-drill it so the gib is correctly located, since the current wonky angle of the triangular gib clamps funny.

    All in all, I'm pretty happy with the protractor. It's great for inside angles, such as measuring the included angle of a dovetail.

    Here's the original Russian protractor that Dimitry posted (from which the Chinese protractor was copied):



    ...and here Dimitry has posted some pictures from the Russian manual of the measuring setups you can do. There's no documentation included with the Chinese protractor, so Dimitry's pictures were extremely helpful:

      Heck, for the money even if it is a "kit" you got your nickels worth. Looks like just what i need for a new mitre gage for the table saw.
      Forty plus years and I still have ten toes, ten fingers and both eyes. I must be doing something right.

        Make it fit.

            I don't normally by cheap tools unless there is an easy way to return/exchange it, but since Lazlo had good luck, I went ahead and gambled the few dollars.
            The fit and finish on mine was quite good. The tightening stud was bent a bit to one side, but was easily straightened. The gib/clamp sat at an angle, so I 'blued' it up with a magic marker and did a little filing until it fit to my satisfaction.
            There were also a couple of burred edges on the square which took only a moment to correct, so after 10 minutes of finish work, I am left with a very serviceable unit.


            Here is a copy of the chart in B&W for anyone who might want one:

              that looks like a very hand gizmo. I've a couple of vernier protractors and a couple next to useless protractor head that comes with a combo square.....they're all quality brands but by the design more often than not you can't get them into a setup....the $17 chicom gizmo might out do them all.

                  There are a coupla sellers on ebay selling these - one is in China(with zero feedback), another is in Ontario, username: Promo4less. If you search in Business and Industrial for "Protractors" you'll find them.

                    Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.

                    It is true, there is nothing free about freedom, don't be so quick to give it away.

                        Is that so you can measure to 720 degrees ?

                            They're still the same price from "Nonstop-Bid" (the seller in my original post):
                            http://cgi.ebay.com/ws/eBayISAPI.dll...m=120217147726

                            They don't have any BIN auctions left, probably because so many people reading this thread bought them
