Review on General Tools 523 Adjustable Trammels by Harwinder Duong

I bought a pair of these mounds over 30 years ago and only bought new ones after the old ones wore out. I do a lot of work where I have to plan and cut out large curved pieces to create landscapes. With these trams I'm only limited by the length of boards I have or can put together to draw a curve. (I've used them for turns up to 50ft radius). The only downside is that the pen holder doesn't fit a standard sized pen to draw the curve. I have to remove the clip and put a pencil or marker in the slot. The new trampolines feel a little heavier where the set screw goes through the body where the old ones have worn down. Thanks for the improvement, I'll probably pass this on to my son.
