Taytools 468310 Large Adjustable Trammel Head Set Beam Compass, Pencil Holders, Hardened Points

I took some time in deciding which trammel points to buy, and these seemed the best quality for the price. Indeed they were! Very solidly built, easily accepts a pencil for marking if desired, and simple to adjust!

Well made. Sturdy. Can use a bic type pen or round pencil.

Substantial trammel set. They are well built but could use two improvements:

This tool is heavy duty, not made of cheap plastic. I was impressed the moment I opened the box.

This is a well machined heavy-duty instrument to draw circles on big pieces of wood or on irregular surfaces. All you need to supply is a beam or piece of wood on which the 2 points are placed. It is far better than even an expensive drafting compass for that purpose. Highly recommended.
