I've decided I can't go on without a buffing machine like the SM one I once owned. I don't really want to spend that much money so I want to build my own. I need a 1x36 shaft/arbor. What is the thread kength? Once I have that, I can build it easily. |

After thinking more, instead of threads, I'm going to try stop collars. I think I can squeeze them together tight enough for buffing. A little slippage never hurts anyway. Next thing I need to figure out is how to reduce a standard motor to run slow enough. I have a motor and don't want to purchase a slow speed one. I wonder how big the shaft wheel will need to be. |

Hutch-- A Shop Fox buffing arbor costs roughly $140 USD, shipping included: https://www.grizzly.com/products/shop-f ... 5MQAvD_BwE Not the same as the StewMac version, I know, but I think it is a lot better than trying to build one yourself. Just my opinion. A benefit of the Shop Fox model is that it has a stepped pulley, so you can change the RPM. |

How about a go kart axle like this, https://www.amazon.com/GoPowerSports-Ax ... 87&sr=8-26 |

Yup, I ordered the SM buffer minus the motor. |

Hutch I'm late to the dance but OLFer Bruce Dickey RIP built and documented here on the forum one of the nicest buffers I have ever seen. It had a long shaft so you were nice and far from the center support and motor. Maybe do a search on Bruce's name if interested? Also the motor size is critical on a buffer and since a buffer can grab and throw a guitar you really want a motor small enough not what we usually go for which is big enough you want a motor small enough that if you really dig in with the buffer you can stop the motor. If I remember correctly no faster than 1,100 RPM too to help avoid burning through the finish. A really good guy to talk about all things buffers is my friend OLFer Joe White he'a s professional finisher and really knows his stuff. |

It's the pully size (sizes) that reduce the motor speed. This is the best tool I've ever found for that, it will even calculate your belt length, which you will nedd if you are building custom: https://www.blocklayer.com/pulley-belteng |

So you may have noticed that I went ahead and bought the motorless SM buffer. I have a 1/3 hp 1700 rpm motor I can take off a tool I don't use. I can't remember but I think I used a 1/3 hp when I last had this buffer. I'm not sure. I'm going to try it before buying a new or used one. |

I think the weaker motor may haved saved me from a burn through or two. I'd looked at the Shop Fox one, but glad I got the SM one for the shaft length since I switched to classicals built the Spanish method with the neck and body integrated. It sits on a sled that swings down from the ceiling so I'm not taking a hit on floor space except when it's in use. |

Is the motor above or below? How stable is it hanging? |

Hutch, here you go - viewtopic.php?f=10101&t=55339&p=727668 Pat, I always envied that setup. I have since then expanded my shop and have room for a buffer on a pedestal, but when I was in the smaller area in the basement I really wanted to make that thing happen! |

After reading that thread, it was mentioned that the SM buffer used a 3/4" shaft. The one I ordered has a 1" shaft. Now I'm wondering if the last one I had was the 3/4" and when did they change it.. My original buffer only came with medium and fine compounds. Now it comes with an extra fine as well but not the extra buffing wheels. I suppose I'll have to buy another set someday but for now, I going medium to extra fine and see how that goes. |

Nice! Yes, they still sell the 3/4” shaft wheels (12”) but the one you’ll get is 1”. Sent from my iPhone using Tapatalk Pro |

A 1” shaft will be a lot more rigid than a 3/4” which I found to be a bit whippy. |
