| Post subject: | Buffer Questions |
I am in the market to add a buffer to my shop. I have been eye ballin' the StewMac buffer kit but at $650, lookin' is all I am doing right now. I found a used Jet JSB-10L 1ph, 1725 rpm buffer in excellent condition for $200. MUCH better price!!! My question is, how will the 1725 RPM work for buffing guitars? I have not used a buffer before so have no idea what is ideal. Everything I have done to date has been done by hand or with my RO sander and micromesh. Will this speed generate too much heat with a 12" buff? If I did the math correctly, the StewMac at 750 RPM with a 14" buff has a speed of 62.5 MPH. The Jet at 1725 rpm with a 12" buff will have a speed of 123.2 MPH. Thanks, Carl. |

I use a 400 and 700 rpm buffer. I use a shop fox buffing arbor with a 1/4 hp motor. I use a 12 and 16 inch buffing wheel. Can make this for about $250 or less. http://www.grizzly.com/products/Buffing-Assembly/H3559 |

I have been using the Shop fox but I do use an oversize 16 inch buffing wheel. After 5 years I haven't had a problem and have plenty of room for buffing but I agree the longer shaft is nice. You have to be aware of the clearance of the guitar body as you work on a buffer so you don't bump into things. That is why I used the over sized wheels . Also you don't need a lot of power . I use a 1/4 hp 1725 motor and it is set so that I can stop the wheel by hand. This is a buffer not a grinder. Also think about padding the floor in case you throw one. It isn't a good thing to happen. |

It isn't a good thing to happen. I thought I was the only one that did that. I have my belt set so it slips too. I find there's no other way to get into tight spots without ripping right through the lacquer. It's also nice that it lets me know when I'm pushing too hard. Just a light touch is really all it takes. I happen to have the previous version of the SM buffer...I just picked it up a few months ago. The new version is probably even nicer. I have to admit that it's expensive, but I don't think it's overpriced. The entire system is very nice. I just ordered more buffs for it. I have a dedicated coarse compound buff for metal. It's basically black now so I can't use it for anything else. I LOVE polishing nuts with the fine compound. It's so much quicker than buffing it by hand. |

I use the same ShopFox John H is talking about. With 14" wheels. I would like to find the 16" wheels, but no luck so far. I get mine from Casewell. They last forever. I bet I have $250 in my buffer. I found an excellent 1750 rpm, 1/3 hp motor on ebay (I think). Loose fit belt. I believe I use the Canton Flannel wheels. Two on each side. I can stop the thing with my hand. RPMS are about 800. Snagging the guitar and it getting tossed is always a risk, but not a huge risk with a setup like this. Take your HP & RPMs up, and it becomes way more likely. I have yet to get a snag that even remotely worried me. Mike (hoping John H will reveal his source for 16" wheels!) |

After looking at the Shop Fox and Grizzly ones, I bit the bullet and bought the previous generation SM buffer ( they just announced a new one in the last month or so). It was the biggest single tool expense I've had in years, but I have no regrets. I did junk their belt and put on a link belt. Much smoother. Pat |

Thanks for all the input. Think I am going to continue saving my pennies and get the SM version. |

I use a Caswell buffer. http://www.caswellplating.com/buffing-polishing/buffing-machines/3-4-hp-buffing-machine-1100-rpm-machine-only.html No belts or external motors to deal with, and cost alot less than the SM deal. I don't tighten the buffs super tight so they'll slip if it grabs the guitar. |
