In part 4, we take a look at a deluxe crosscut station, complete with a lumber rack storage area on the backside. In addition this unit features a tilt-out bin, sliding drawers, adjustable shelving, and customizable pigeon compartments. Designed by Craig Bentzley and built by Joe Hurst-Wajszczuk, this article is written by Paul Anthony and is featured in Woodcraft’s October/November Magazine, Issue #43.
Quits springing back/jamming after < 100 holes. Horrible. Returning it to get a snappy and trying that one. Avoid.
First one failed
After a few hundred holes, the sleeve stopped springing back down. I had to use pliers to grip the sleeve, then rev the drill a little, to get it to release. Then the sleeve 'came out'. I am not sure if was ever 'attached' to the spring or just was magically held up. Finally, after doing a few holes manually (placing the sleeve up against the spring), the sleeve was 'grabbed' by the outer shell, and won't come out (up or down). I am returning it for a new one. We'll see. It's great when it works, but a pain otherwise.
third time charm???
My first one of these fell apart and was replaced by you. The replacement did the same midway through a project. I ordered another one to finish up, but there already signs of a repeat failure. I'm not drilling thousands of holes at a fast rate. Maybe one to two hundred every now and then. Most small bookcases easily have that many. I have looked at other units but they look like they are all made by the same company. Hopefully this third one will hold up a little longer.
This bit works very well with the jig for drilling holes in the kitchen cabinets for shelf pins. Simple, easy to use, you can't make a mistake, unless you try very hard!
Guide Metal to soft.
This bit easily clogs with wood chips, and the guide is made of soft metal. I have had to disassemble and sand out burrs in the metal guide after limited use.
can use some beefiing up
Drilled about 50 holes with it and the walls of the guide twisted and seized the bit. There are three holes in the guide and the legs between them seem weak. Woodcraft replaced it immediately and all has been well, so far, with the new one.
