Surrey/kent Engineering Firm

I need to get my air inlet manifold sanded down, after having hacked off the main bit.

Does anyone know a small firm or something in Surrey/Kent/Sussex who might do this cheaply?

 

I can send it off to GBS but it will end up costing £40 with postage and I haven't quite got the courage to do it myself with just a single file available to me.

Any engineering company that can skim a cylinder head should be able to do it.

This one looks OK, dont know where in Surrey you are?

Honestly, I will sand that down myself. Take it really steady and finish off with a hand file. Polish up the surface and get a 1mm gasket to go in between to take up small imperfections. £40 is quite a lot

Just remembered how I used to remove cylinder head imperfections

in pre-electricity days

 

A thick sheet of glass, or flat iron plate, place a sheet of wet&dry on top

(grit side uppermost!) & slide the part back & forth until you have a uniform

shine all across it.

 

I wasnt the only one that did this....

As Bob said -- a 6mm thick piece of float glass with wet & dry will do the job -- presume its an ally manifold so use the wet & dry with paraffin or white spirit to stop the paper clogging.

Hmm, they're only 30 minutes from me. Problem is, the manifold is only plastic (air inlet on a Zetec) and I've contacted a similar firm who weren't interested (well, they never replied to my email). I'll give them a go...

 

Would prefer to do it myself but my history with straight filing is not good and I don't want to get this wrong, otherwise I'll have air gaps round the Plenum. I've got some instant gasket - will that do as well for hiding any imperfections?

Okay, get the rasping tool on it. Leave a few mm proud. Hold in a vice, get a rough sanding paper, wrap around a 2 x 2 wood and sand down slowly. swap for finer paper as you progress. Job done in 30mins.

Precision engineering at its best.

I thought it was ally, I didnt realise it was plastic.......

10 minutes max should do it.
