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

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.

Great quality Trammel points help me build a 46 inch arc out of walnut. High quality steel construction

These are substantial, flexible in use of ruler and very easy to change in length of radii.

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.

Worked great.

Was easy to put on board to draw the rounded arches I needed

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

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

Performs as expected

There are great!
