Here for you help again. Nephew tried to "polish" :mad: the blade on my Delica with 1500 grit wet/dry, now the steel has a brushed appearance (not what I want!) Any thoughts on how to get the polish back from the 1500 grit stage? thanks
 
If you don't have a buffing wheel and some buffing paste, get some 1500 grit wet-dry sandpaper and make sure that the marks on the blade are all going in the same direction. Then, get some 2000 and 2500 grit wet-dry sandpaper and sand with the 2000 and polish with the 2500.
 
Thanks all, I'll give one of the two methods a try. Maybe its time to get a buffing wheel!
 
Be careful, a buffer can be very dangerous. I have heard plenty of stories of makers buffing a knife, and the buffer throwing the knife across the room.

You should be able to get just fine results for a user if you just advance through the higher grits of SC paper.
 
A polish that I have used in the past on various types of metal is a polishing paste called simichrome. I have gotten mirror type results. It is available from Brownells (they have a website).
 
CAREFULL! I worked for a company making parts for turbine engines and I can tell you that a buffing wheel can and will grab the steel and throw it. Try to keep the blade in the center of the wheel and don't go to long 'cause it will heat the steel if you apply heavy pressure or hold it there too long, don't want to remove the temper. Some fine grit buffing compound will help.
 
It all depends on what finish your looking for... you could just move threw the sand paper going frome course to fine... if thats enough to get it back to the same finish it was before... but if you want it to sparkle .. get some diamond paste ... I use it for finishing molds in the machine shop. use a a bit of wood to rub the paste into the metal. all depends on how much time you want to spend on it... I've also gotten pretty good results using wenol metal polish... most hard wear stores carry it.


Hope this helps,

"Mothers Mag and Aluminum Polish"..............absolute best stuff I've ever used to polish a blade. It may take several polishings, I like to sit in front of the TV and polish, but you can get some excellent results.
 
Thanks again to everyone for all the great advice. Tried (very carefully!) a 4" buffing wheel with some white compound and got so-so results. The blade still looks like it's been buffed. Would the next step be something like the Mothers mag or simichrome?
 
Did you clean it? (sorry to ask this question...but it's what came to mind first - cleaning off the buffing "marks")
 
Yeah, I cleaned the compound off after buffing. I mis-spoke in my second post, the blade didn't have buff marks, it just had kind of a matte finish. Took artsig1' advice and bought some Mothers Mag. Damn, that stuff did the trick! Appreciate the help :)
 
Hey, I'm telling ya'....that Mothers Polish is the TRICK!! Just continue to polish on it when you have time or when sitting in front of the TV and you'll be amazed with the results.
 
2000 grit sand paper and then use ? ah i forget........its something you can buy from autozone and it has jewlers rouge in it so that might be the trick. i polished a mayo northshore for a customer. handle had scratches all over it and i put it on the buffing wheel with plain rouge and it worked well. not perfect be well
