Hybrid_From_Hell Posted October 23, 2007 Share Posted October 23, 2007 Right, I have a few of those "Roundtoit" jobs, the ones that always seem to be put off as something more importnant comes along I now want to sort out the Eales Rocker covers, they have about 7 coats of paint / enamel etc on them, I seriously doubt Nitromors will do much to them I wnat to get them back to ally, shot blasting will be to coarse, what are the options please ? They are "Bare" so anything can be used, and them clean off properly before doing a "LR Bling Thing*" on them Nige * "LR Bling thing" - A BBC Process on V8 Rockers Quote Link to comment Share on other sites More sharing options...

Roverdrive Posted October 23, 2007 Share Posted October 23, 2007 Bead blasting might be kinder Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted October 23, 2007 Share Posted October 23, 2007 yup, bead or walnut shell blasting will work fine on the ally i reckon. Quote Link to comment Share on other sites More sharing options...
rtbarton Posted October 23, 2007 Share Posted October 23, 2007 Blasting may not shift powder coating, I've had to give up on several powder coated items. There are chemicals that will do it, but most seem to be in the USA. One of my customers soaks stuff in a chemical, but he's very cagey about what it is, and don't forget caustic chemicals eat ally! The way I treat ally engine parts is to blast them with very worn abrasive and then blast with glass beads, this gives a nice satin finish that isn't too bling. Then they could be polished I suppose. The guy I buy my media from suggested using Aluminium oxide and then glass beads. Quote Link to comment Share on other sites More sharing options...
rtbarton Posted October 23, 2007 Share Posted October 23, 2007 .......walnut shell blasting will work fine on the ally i reckon. Yes but you need a blooding big nozzle Quote Link to comment Share on other sites More sharing options...
Les Henson Posted October 23, 2007 Share Posted October 23, 2007 I did shot blasting a good few years ago now - from chilled iron particles to copper slag. Pearl beads were used for the likes of copper, brass, stainless, magnesium, and alloy. It barely marks the metal. I bead blasted the side casings on my suzuki and then polished them with Solvol Autosol and it didn't take very long. Some plastic-type coatings would smear and turn black before eventually coming off - if the coating did this we would use something more abrasive, such as oxide to remove it and then pearl beads to get the surface back.

Sounds the job !...but what is the "Pickle" what am I asking for them do do / shove it in ? Nige Nige I have a couple of local companies near work (LA - Littlehampton!) Hourcover and Eurofinish - we use them for a lot of powder coating but I expect there are similar in Guildford/Portsmouth, if you just want to strip I expect a few quid as the setup times for PPC costs I had some VW golf ally wheels done some time ago - they dip them in an boiling acid I believe - stripped all of the lacquer but as noted left them very dull. Shot blasting is an option but is more specialist - we have a shot blasting set up at work but is designed for steelwork rather than alloy - it would be too harsh fo alloy, but Penfolds at Barnham or if they are still going Blastreat at Arundle. Hope this helps Steve Quote Link to comment Share on other sites More sharing options...

Hope this helps Steve Blastreat still in Arundel and very busy, well they were in July when I delivered some parts for coating. Crushed walnut shells are used by Parker Pen to get their burnished finish on stainless pen caps, used in a rumbler overnight apparently! Concord Lighting in Newhaven have a furnace process to remove powder coated surfaces from steel parts. However, it runs at about 700 deg C so not much left of your aluminium casting Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted October 24, 2007 Share Posted October 24, 2007 Another one is K & N Finishers in Portchester (Portsmouth), I've used them to blast some stuff before - minimum order is £20 though, can I throw the rocker covers I got at sodbury in with yours Nige?

bill van snorkle Posted October 24, 2007 Share Posted October 24, 2007 I work for a specialist engine reconditioner. sand blasting is too risky in a workshop around delicate components, so we use Bi Carbonate of Soda of all things for blasting alloy timing covers, rocker covers sumps etc. I don't know how well it works on multiple paint layers but it removes hard baked on paper or cork gaskets pretty good. bill.
