Do I trammel? Of course! I'm a sucker for them

Many years ago Satanley trammels were 100+ on the 'bay, but on the drafting
tool side you could get micro adjustable steel beam trammels for 15% of
that. That has changed now.

After many years, I've got a fair number of them.

From trammels you may likely translate into ellipsographs!

Fair warning....tis another slippery slope....been there and done that.
