Grizzly G0540 horizontal boring
Several weeks ago there was a thread about using the Grizzly G0540 horizontal boring machine as a mortiser. I have a rather large order for some custom windows coming up and this seemed like just the thing to tackle the joinery.
I finally got a chance to get it adjusted and make a few holes. The unit is quite heavy and very solid for a piece of machinery this inexpensive ( $ 375. plus $ 75. for shipping ). The X,Y table movement is nice and smooth with no play or slop ( well, none that I could detect ). I used a 5/8″ end mill and removed about 3/16″ or so in each pass in red oak with no problem. Deeper plunges, however, seemed to put a bit of a strain on the motor ( side loading ) causing excessive chatter. Shallow passes seem to be thew way to go.
One thing it can’t do is center a bit on 3/4″ material. The table won’t go high enough to do this. An auxiliary table would fix this plus, if properly designed, could help with registration of the work pieces. It could also use a locking device on the elevation control. Although it didn’t move during use,it would seem more secure if it had one.
All in all I think it will be a good addition to my small one man shop. How long will it last? At that price it doesn’t have to last long.
