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

I find this very easy to use and in complete agreement w/ everything the ad says about it. I recommend it.

I have been making large shop drawings with trammel points for more than 50 years. These are the biggest, strongest, heaviest (cast iron), best designed trammel points that I have ever used. Designed for clamping on wood or metal bars of any length. They are built like a mack truck. Great for heavy hard use on large drawings, and job site layouts. Holds pencil firmly and in multiple directions. Unbelievable quality. Great price. All other trammels are toys by comparison.

Don’t let the picture fool you they are very well made.

These were a great, inexpensive alternative to other brands. I dont use them often but I require good accuracy when I do. These are perfect. I bought a vintage 4ft wooden ruler and ripped 1/8 off the width and now I can draw and cut 8ft circles and arcs.

I attached these to a 1x2 piece of wood so I can draw perfect circles in a piece of wood. Then I cut the wood using a drill and jigsaw. Worked like a charm. I hate using a rope around a nail. This is way more civilized. The quality of the product is very high. Its a sturdy metal unit, well-painted. A couple of reviewers mentioned that it doesnt look pretty, but I actually really like the retro industrial feel. The carbon tips are also really sharp, so it wont slip in the middle of a job. Worth every penny!

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

These are heavy duty and accurate. You can easily switch out the point for a pencil to draw or your circle. There is no jumping or sliding and its very accurate.

These make a solid beam compass as big or small as you want. Pencil fits in perfectly, and they have a good weight to them

These are stout! Seem extremely well built. One oddity that doesnt affect usability...the knurling on the knobs dont match.

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