What kind of polishers sanders are people using especially in the waste area. I use my 5" on most of the body of the accoustics but am thinking about a pneumatic or electric 3" which I think would be better in the waist area. I like the idea of the traditional pneumatic shape but do any of you make the other type, like festools, work. What do you think the smallest compressor I could use with a 3" would be. they seem to be around 10cfm

Just faced the same decisions. Searched for a 3" RO. Mirka has one but the one with the smaller orbit was not available in USA. The Festool was 3.5" And just looked like it had too much off center weight for my liking.

I went with a Festool 5"RO with 3mm orbit which you already have equivalent of.

In the waist area I'm using pneumatic handheld drum, just pump it up a little harder and use it lightly and it works really really well.

I like the bigger dia for sides. Best neck shaping tools out there for smoothing too, IMO.

I wonder if you could make a wool sleeve for polishing? You got me wondering.

I have a few of them. This one is a good all around unit. It has different buffers so you can do about all you need
look up dallas detailers on you tube they explain the process well , Yes it cars but finish final buffing is similar.

you will learn not all pads are used for everything and they teach you the different comounds and what they do. This is not just
smear and shine , there is a real process involved.

The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.
