I took a look at some of the previous reviews for this kit with some scepticism but I should have taken notice. The kit seems robust enough and easy to assemble but struggled to cut a full thread at 1/2" bsp, even with cutting lubricant, resulting in cutting 1/8 of a turn at a time and then backing off, the die just doesn't appear sharp enough to cut a thread. The die head then also became jammed in the collar meaning I had to punch it out with a hammer and block of wood. Surprised at Clarkson as I've had equipment from them before which has functioned perfectly.
