Alex, any item you produce or rectify on a CNC machine is "precision machined" simply by the very nature of the machine and procedures used to do it. You know that.
Obviously it's at the very simple end of engineering, but let's not split hairs.
It still needs gripping, clocked, probed for the profile, then machining. That is "precision engineering".
And if your guy can do the above on 4 rims quicker than hanging them and painting then he's either a machining god or terrible at powder-coating.

Erm, don't know where to start with that.
We are talking full refurb here.

You can buy those CNC wheel lathes off the shelf and read the pamphlet it came with to learn how to use it. Any monkey can operate one after a few hours self learning.
I'm sorry but "Precision Engineering" in my book isn't something you learn how to do in a few hours reading a pamphlet. There's more skill in operating a Hunter Hawkeye correctly and I would deem that Precision Engineering either. _________________ 2000 Manual 996 C4 Arctic Silver Convertible

My local place has £100k of HAAS CNC lathe. Regardless of how easy the job is you put on it, it's precision engineering. Whether you agree or not doesn't matter. It is by definition precision engineering.
Yes it's child's play compared to proper CNC'ing but it's precision engineering.
We are getting way off topic here. I'm arguing the fact that those who pipe up, as you did that split rims are no harder to, or more importantly, anymore time consuming to refurb than one piece wheels, are totally incorrect.
£800 is a lot but as I say any less than £500 and I'd be wary.
Simply look at the process -
1 piece - 1) Shot blast
2) Powder coat
2/3 piece - 1) Dismantle wheels sorting any snapped bolts.
2) shot blast components
3) powder coat components
4) Diamond cut rims on CNC lathe.
5) Rebuild wheels using relevant locking agents, etc.
If anyone can't understand that the 2 piece wheel takes more time and expensive machinery to refurb, and that more time = more money then that's slightly astonishing.
Anyway that's all from me. I just have an issue with forum experts shouting "Rip off, rip off" at anyone getting on with their trade. Half the time as you proved you were comparing apples with oranges.

Agreed Mark. I wasn't disagreeing about the 2 piece process and assembly/disassembly, just that diamond cutting wheels has been deskilled so that any monkey can do it. The precision is in the machine design/manufacture and not the operator.
Op - give these guys a call and get a quote: http://www.diamondrimsltd.co.uk/ _________________ 2000 Manual 996 C4 Arctic Silver Convertible
Thanks to the challenge of the price I was getting quoted and Marky911's explanation of alternative refurb approaches, I've now got 2 quotes from reputable local companies at the sub £500 region including VAT. This is to split the rims, dip and paint and includes tyre removal\refit.
Am still thinking of a change though

Sub £500 is much more like it . but if you fancy a change then why not. _________________ 911 Owners,Some Invest In The Future,

Now we're talking. That's more realistic and what I'd expect the price to be somewhere near.
Get them done. You can always change at a later date and move them on in mint condition. _________________ 2000 Manual 996 C4 Arctic Silver Convertible

Or selling them in pre-refurbished condition allows you to sell them cheaper (you won't see the cost of refurbishment back on resale) and it allows the buyer to have them any colour/finish they choose to match their car/taste?
Selling cheaper will also get more interest from buyers happy to use as is, plus less seller fees through eBay if you go that way _________________ 1998 C2 Manual + The Full Hartech.

Interesting thread, don't often get time to contribute to these much these days.
It's very easy to explain how a set of SCII splits get to £750-800. I'm happy to put together a breakdown if anyone wishes. It simply depends what you are getting, and what you are starting with. You have to specifically work with these wheels to know what 'should' be done versus what 'could' be done as well as what 'can' be done. I really have to bite my tongue reading some of the comments above.
At the low end of the price range you will get what you pay for, and the saying buy cheap buy twice is very true. The issue with splits of this age 15-20 years they'll have been done 2-3 times meaning the rims are getting thin, the bolt holes badly corroded to the extent the threads are barely functional, powdercoat is put in the wrong place etc. There are some outfits that are, frankly, putting out dangerous work. It really comes down to questioning the refurber and seeking assurances on the process etc etc not just assuming. _________________ The Unique Wheel Refurb & Tyre Service with Loan Wheels
