Default Fast or slow. Heavy or light

I am new to turning pens , and want to try and get the best possible finish on acrylics. Do you sand through 12000 micro mesh at a high or low speed? Heavy pressure or light preasure? Any feedback would be a great help. Thanks guys and gals

Low speed, wet sand, light pressure. First I wet sand with 400 before I MM. Then after MM I polish with Maguires Plastx at medium speed.

My heavy handed sanding has caused me many hours of extra work. Sanding with light pressure is the way to go for finish work.

Some new turners don't realise how much material wet and dry sanding can remove even with fine grits so, I support the advice giving above...!

Cheers

Low speed, wet sand through 600, MM with a light touch through first three pads (1280 I think) followed by three coats of PlastX

Instead of heavy pressure, use lower grits and move up using the next up grit. I have noticed over the years that "heavy pressure" is used when a slight defect is noticed and one (we or I) want to get it out without having to go back down a grit. Take your time and enjoy the journey of pen making. It is the enjoyment of the journey that produces the best pens.

You are going to get a ton of excellent, up to date advice from experts here. You also may try in the search box "Scratch free acrylic Finish". You may find a process that appeals to you. Happy turning and finishing!

Also remember to wipe down with a "clean" paper towel between grits. Especially if you are using cheap sandpaper, one grain of "sand" from a lower grit will devastate a smooth finish.

I agree. Low speeds. My pen lathe goes down to two hundred something. That's good. I also support clearing off the mess from the previous grit before the next one. I keep separate "baths" of water for each grit (the plastic cream cheese tubs from Panera work great ��).
