70036 Yardstick Compass Circle Maker, Lead & Pin Post for Large Circles and Arcs, Fits Standard Yardstick or Ruler, Drafting & Woodworking Layout Tool

Received in good time, but when I received it, it only came with one lead. I measured it (2.4mm or .095inch) and proceeded to look for more online. I wasn't having much luck until I ran across "compass leads". They are advertised as being 2mm in diameter. Amazon has plenty. You just have to use the right search terms. The compass works great too, but the leads will break if you aren't careful. The slot is just over 1/8 inch wide, so won't fit some rulers/yardsticks. Stainless steel rules work, but swim in the slot. You just have to make sure the pieces are tightened well, but not too tight or you risk stripping the threads.

Great concept but the final product is junk, took a lot of effort to get the job done. For less cost, less time, and less effort, you can tape a nail and your choice of writing utensil to any stick, ruler, or tree branch and get the same or better results. Don't waste your money on this. The plastic caps that cover the lead and point obviously weren't designed for this product, don't fit properly and quickly broke. Had trouble finding a ruler of appropriate thickness that will work with this, ended up buying an aluminum yardstick from the orange big box store and used bits of cardboard to make the parts fit securely. The part that holds the lead only comes with a tiny piece that broke almost immediately and I had to buy more just so i could use this product.

The pin is long, requiring the lead to be long, which means it breaks easily. Barely got a half of a circle completed before the first lead had broken beyond use. Then there is no easy way to replace the lead.The two pieces were not manufactured to anything close to tolerance. One piece was adjustable and worked and the other was so far off that even after adjustment it would not fit the ruler snuggly. Just more Chinese junk and a waste of money.

I am an illustrator and have been designing coins lately so I needed a tool that would help me make big, perfect circles. This yardstick compass is excellent for that! You just slide the anchor and drawing points on the ruler, set them at your desired lenght and you are ready, not much to it. Excellent product.

The product arrived very quickly, the items looked great the Lead was loose in the cover and I thought that I had to attach it before use, but after opening the package my excitement turned to disappointment as the Lead was actually broken. After paying $18.17, for the item the shipper could have taken a little more time with the packaging knowing that the item had a delicate part. For this reason I gave them a one in my review. Also if you are going to use it with a Yard stick, it must be a thin one. I have a very old Dritz yardstick that is about 1/4 thick and it did not fit in the slot which is a 5/32'' width. this important information was not part of the advertised description.

This compass draws circles and arcs beautifully. But the collet that holds the lead will also hold an X-Acto blade as shown in this photo. Cutting circles requires care but works well.

These scribes attach to a metal ruler (not supplied) or any other thin, flat slat. They lock in place nicely, therefore holding their measure. Very easy to set up and use with protective caps for the point and the lead.

This is just what I wanted. It fits on some wooden yardsticks but not all. You need the thin ones. Also, fits on the free paint stir sticks you can get at the big box stores. They are about a foot long.

this compass does not even fit regular rulers much less the ruler Amazon recommended to buy with this. furthermore there wasn't even 1 spare lead with it. your product is rubbish and I am disgusted with Amazon and your lack of specifications on products

In realtà non è niente di nuovo. Strumenti di misurazione del genere si usavano centinaia di anni fa, e ne ho visti molti autocostruiti nelle botteghe di falegname che frequento. Io ho sempre usato i classici due chiodi con la cordicella, o un chiodo e una matita. Sono due cilindretti di alluminio, ci si infila una riga, si stringe il cappuccio e si ha un compasso. Sulle righe da falegnameria in acciaio e alluminio ci stanno perfettamente, e il bello è che si possono usare righe corte o lunghe, per avere compassi con un raggio anche di vari metri. Sono forniti di due cappucci di protezione e le mine sono le classiche che si prendono in cartoleria a pochi centesimi. Al posto della mina si può mettere un chiodino, per avere due punte. Carini, credo che li userò nei miei lavori. Ottimo il prezzo e ottima la spedizione, al solito.

IT DID THE JOB, BUT JUST, WAS HARD TO FIT ON TWO DIFFERENT RULERS, CAME WITH ONLY ONE LEAD THAT WAS BROKEN IN HALF IN THE PACKAGE. CONSIDERING THE PRICE I PAID FOR THIS, THEY COULD HAVE ADDED SOME EXTRA LEADS. THEY ARE NOT STANDARD SIZE PENCIL LEAD PEN REFILLS EITHER, SO WHERE DO I GET MORE LEAD REFILLS ? OH, I HAVE TO ORDER THEM ONLINE. MORE WAITING FOR ANOTHER DELIVERY AND MORE COST. WAY TO MUCH MONEY FOR WHAT YOU GET. NOT WORTH IT. CAL

La idea del producto es muy buena para utilizarse como compás grande, no obstante, por el precio que tiene me esperaba mayor calidad...Se entregan dos piezas metálicas con un acabado muy basto y no muy agradable al tacto. Tanto es así, que las roscas encargadas de asegurar que la regla no se mueva son difíciles de ajustar y en casos de reglas normales (las plásticas) se salen y es imposible trabajar. La punta de grafito que trae es simplemente inservible. Blanda, quebradiza y sin pigmentación alguna. Finalmente, los protectores plásticos que lleva para evitar roturas en la mina y pincharse con el punzón son bastante malos y se rompen en seguida.En definitiva, gran idea, pero muy muy caro para lo que es.

It works (it's simplicity should prevent failure) but it is rather cheaply made and way overpriced. No where near the same quality at all compared to the one my father had decades ago.
