buffing speed

John F.

>Yesterday I tried for the first time to buff a lacquer bowl.....With horendous results. I burned thru the lacquer in miliseconds, pulled the lacquer into huge piles, ok, so this is a test bowl, I spend the rest of yesterday wet sanding the mess back into some resemblence of decency. Today I will be shooting another coat of lacquer on it.

My assumptions are that one, I didnt let the lacquer dry long enough before buffing, and two that my buffer speed was set too high.

At what speed should the buffer be spinning, guess what I really need is what surface speed it should be at, I have 3 different buffing wheels and they are all different sizes.

>LET THE LACQURE DRY !! depending on your humidity, 1 week should be goo. 1300-1700 rpm is good for speed . Use a light touch and make sure the wax wheel has very little wax on it. A little goes a real long way. If you think you have enough on the wheel, you probably have to much. Best of luck, Sean

>John when you get the secret, let me know. I've given up using a buffing wheel on lacquer for that very reason. I use 3-m Finessit compound with much better results.

>A good lacquer finish requires time and patience. Buffing the lacquer requires more of both.

The lacquer has to be DRY. If the surface smells like lacquer, it isn't dry. Wait until there is NO odor, and then wait another week to make sure. This can be from a couple weeks for a brushed-on coat of Deft, to as long as several months for a very thick film. A dry climate and good air circulation will make the wait shorter.

DO NOT let the wood surface get hot while buffing. Use a light pressure and a minumum of abrasive on a soft wheel at slow speed. 900 RPM is good for the 8" Bealle buffing wheels on dry lacquer.

>I don't use much lacquer just on small things like Christmas ornaments. I useily let the lacquer dry for a couple of weeks. After it's dry I will buff with 0000 steel wool and then go right to the wax with a "light touch". Don't let it get hot.

>I prefer to buff at a lathe speed where the buffing wheel is still a bit "soft". Too much speed and the wheel gets "hard" and very agressive. Try buffing at a lower speed than you have been using and see if it makes a difference.

>To start with if you will apply the Deft deluted about 50/50 or thinner and saturate the piece untill no more will soak in. Then wipr the piece dry. allow to dry at least two hours and then put on another coat like the first one and allow about three or four hours to dry and then buff at any speed. You will not roll up the finish and you can buff untill you get the luster you want. I use the red and white compound that comes with the Beal system. I don't use the wax they furnish.
