I bought this few months ago to upgrade some products that been selling well to a 2 piece from one piece ( also raised price few bucks) . I use for most part the dowel rods from Grizzly since for price the quality are really nice and have good grains, are not warped ,or loaded with sap either . Okay back to this product the dowel rods here are the size they say so need take some off and tapper the end a bit . Since my products are for food I use my tung oil mix works well . I just put in vise and carefully turn straight and slow . I then back off slow also . take your time and suggest you view a video or two on You Tube to get better idea .
I took a star off since the instruction sheet was nothing just stated turn clock wise and put in vise. I did not see anything about adjusting the depth but the video did although was for a bigger threader was same brand It is good product for money and will buy others of different sizes with shipping cost rising a good way to keep shipping down, give people options to store when not in use , and if seasonal great way for putting up furniture .CrazyBearUSA
