Product Description

By entering your model number, you can make sure that this fits.

These adjustable clamp on trammel heads are ideal for measuring, marking, and scribing circles and arcs that are outside the range of what a standard compass can produce. With your custom-length shop-made beam, you can create an infinite number of arcs.

Any wood beam from 3/8 inch to 1-1/4 inch wide can be clamped by the heads.

Two trammel heads are included in the set, one of which includes an integrated pencil holder for standard wooden pencils. It also comes with a bonus set of points.

Cast iron is used to make the heads.

To allow scribing on steel, sheet metal, or aluminum, the points are sharpened and hardened.

Questions & Answers

Are these, as described (all metal pieces), made of cast iron and steel points for scribing on steel?

Metal is used for all of the points and screws. I'm not sure what kind of metal it is. I've never used them on metal, but I believe they'd scribe well.

It was precisely what I was looking for

5/5

This trammel is easy to operate, has a simple, functional design, and is reasonably priced. When repairing old Autoharps with surfaces that prevent direct measurements, I use the instrument to take measurements and lay out the layout. It can't just be measured with a tape measure. I'm extremely happy.

With pencils, I'm having a hard time

3/5

The pencil holder is a complete waste of time. The starett set is twice the price, but it holds a pencil without issue, so it might be fine if you're scratching with the points.

Friendly to click

5/5

These are fantastic suggestions. I frequently create parts that are curved and round. It was easy to enlarge the opening; I prefer Pentel clicky pencils because they save me time and frustration when sharpening.

It does what it says

5/5

You'll have to supply the "beam," but I was able to get by with just a piece of hardwood.

Trammel

4/5

Small projects will benefit from it. It was used to cut an 18-inch circle out of plywood.

You can buy a half-inch square of aluminum stock and cut these to any size

You can go as long as you want with these.

Junk for a low price

3/5

The points are made of plastic and are not very long lasting. The clamp pads are made of plastic, and I'm pretty sure they'll break soon. I've only just unboxed it, and the paint is already peeling. This tool's long-term viability concerns me.
