Forced rotation or RO? - Makita BO6040

[moogoob]

Hello,



Will one mode or the other yield different results? I know the forced rotation can be more aggressive, but is the RO mode better for finishing?



thanks,

robb

if you`re looking to get into machine polishing for the first time and price isn`t a issue (around $280), check out the Flex 3401. do a search and you`ll find lots of great info on it...

I already have the makita. the BO6040 is a two mode machine: RO or RO with forced rotation.

i have no experience with this machine, check out a few threads here. there might be some info... Autopia.org - Search Results

^^^ Thanks, I`ll check em out.



But not even machine specific, since there are similar machines like the one from festool.



Can you get a glossier finish in one mode or the other?

You can achieve more paint correction with a rotary........

that is prob. true but have you used the machine he is talking about?

if not how do you know?:nixweiss

Well, the adds say forced rotation for "aggressive" and RO for "finish".



While this holds true using sandpaper against wood, I`m just no sure it`s the same for polishing paint.



I guess that the FR mode can achieve more correction due to its "aggressiveness", but I`m not so sure its the same as a rotary because it doesnt get to the same speeds. And the question remains, (worded a bit differently) does the RO mode make for a better finish, just because its less "aggressive"?



Thanks Guys, I really appreciate the input.

I know what you are asking, but it is too much of a "loaded question". A novice can get a better finish with a PC than with a forced rotation machine or a rotary. An experienced pro can often get a better finish (more gloss) with a rotary than a PC.



Too many variables - experience, pads, polishes, paint type, etc...

I think everything is loaded question with too many variables, especially skill.



I`ll try to De-load it a bit. Lets stick to the machines that have FR+RO and leave out rotary and RO onlys. I think Makita, Bosche, and festool make em.



The Flex is forced rotation only (I think)



As for the skill variable, lets shoot for a high skill level as it gives me something to shoot for



example: I have the makita, IP and FPII, and white and orange pads.

I`d use FR, IP, Orange pad to do the heaviest of corrections with what i have in my arsenal.



Next, Switch to FPII and a white pad to finsih. Would I continue to use FR or use RO to get the most gloss?

I was thinking it as a general question. I wasn`t paying attention...........:doh

I don`t think it matters which you use so long as the combo used (pad, product and process) doesn`t mar the paint, which isn`t easy to do in FR mode and near impossible in RO mode.



You can only get the paint as glossy as the pad/product combo will allow. Process (Rotary, FR or RO) dictates aggressiveness and cut, not end gloss.



Personally I only use the 6040 as a RO machine for finish polishing and leave correction work to the rotary.



With what you have to work with the FR mode along with a white pad & FPII will probably yield more gloss because of the additional cut. If you were to use that process on paint that was previously leveled with a rotary I don`t think the FR would give you any added gloss over RO mode.
