Hi all, I just put together my new shopfox overarm pin router and was having trouble getting the pin and bits lined up. I have it really close, but it is about 1/32-1/16" too far back. There is really not a way to adjust this, I have just been loosening the bolts that hold the arm on and tweaking it to line up side to side, but the front to back really doesn't move any more. I was using a 1/2" bit that is 3" long and a Porter Cable 890 motor in it. I bought this to replace my shopsmith overarm router that I also could not get lined up right, but that was due to my shopsmith being a 1963 model and the table would flex and put the bit at an angle. So, how accurate are these supposed to be? I was really hoping for this to be close enough that you really can't tell, but I can tell this amount. thanks John |

Upon closer inspection and playing with it, It is lined up perfectly as long as I don't tighten the router into the collar, when I tighten this, that is when it moves backwards. |

Hi. Overarm routers are classic furniture building machines. The pin on the table is designed to line up concentrically with the spindle and follow a template or pattern. Onsrud Machine of the U.S. was the premier original overarm with a model known as the R8. Later SCMI copied this and made their own R8, as did Grizzly. I own a Grizzly copy myself. These tools are all adjustable to achieve concentricity. I own a furniture and cabinet shop and am building my first guitar. There should be a way to align the pin to the spindle, if not, send it back, it is absolutely essential to achieve concentricity. Without concentricity you cannot use this machine effectively. Attached is a photo of me using this machine to do my first and asymmetric rosette. T |

I was actually finally able to get it aligned, I had to completely remove the arm and re-attach it. It has a rubber gasket between the arm and the table, and just loosening the bolts was not enough to get the whole assembly to move forward. I figured there had to be a way to make it line up because it would kind of defeat the purpose of the tool if it wasn't perfectly lined up, at least for what I want to do with it. It is good to go now, after another 3 hours of fiddling with it. I had looked at the grizzly pin router but way too expensive for me right now, are they any good though? It seemed to be the cheapest "real" pin router. |

The 5 hp Grizzly is a good machine. With CNC routers getting more affordable there a ton of deals available on overarms. If you are in the market for any heavy duty equipment check woodweb.com, their used machinery section is searchable. Also try ex-factory.com. One note about overarms, learn the machine slowly and keep you hands away from the bit by building nice fixtures to create you parts. Enjoy, T. |
