I would like to get a polisher for polishing my pattern to a nice high gloss finish, using a 14mm spindle backing plate.  The ones I see online are (I think) quite large, heavy and noisy (I guess that is the nature of this bit of kit), does anyone have any recommendations?

My favorite polisher is a variable speed angle grinder with a 8” wool bonnet. Had no issues getting my plugs/molds to a mirror finish.

I use the wool bonnet for compounds and then a foam pad with 3m Finish it

I have been considering an angle grinder, and agree this may be the way to go.  I am a fan of Makita's BL motors, they are a bit more refined. The downside AFAIK with the AG is the speed, the Makita has a minimum of 3000rpm, is this problematic with a 150mm pad if I also used it on the car?  The rotary polishers seem to have a low speed, say 700 - 3000 rpm, whereas the DA polishers seem to have a higher speed about 3000rpm - 7000 rpm similiar to an AG.  Any thoughts or advice on this?  I know I will have to keep to 3000rpm.  

I wish I could tell you what speed the Dewalt I used was back in the day. It’s not made anymore. Whatever input I gave the trigger it would spin accordingly, minimum was well below 3k.

Look up Flex Polishers. Likely my next buy. They’re big in the boat and car finish world with a lot of options.

And... if you’re in the States, it’s worth experimenting with Harbor Freights variable speed grinder for how cheap it is.

Yes, agreed, I really like the Flex polishers, very smooth and quiet from the reviews ive watched. I am in the UK, about £350 here.  It's probably worth getting as an investment tool, it is very tempting.  I will continue to weigh up my options for a bit.  Thanks for your input on this Jason, it is very much appreciated.

DeWalt make a polisher that is variable speed 0 - 600/3500 rpm the DWP849X.  Maybe this is similiar to what you had.  Could be a good option for me with the variable speed control, seems quite smooth at low speeds.

Slow speed is clutch if you get a little relaxed with spraying water in the surface. Loved that polisher.
