Ferrari Mailing List: Re: General Part Question

[Hans E. Hansen (FList]

Ditto.

 

In some of my other lives, I deal with micro parts, threads, etc.  It's

not rocket science.  Get the correct tap.  They are not expensive,

but you might have to wait a week or so to receive them.  Well

worth the investment.  Repeat:  Well Worth The Investment.

Use a sharp metric tap and if you're cutting plastic use a lubricating solution of 50% dish washing liquid 50% water.  Go slow and back the tap out frequently to clear the chips.

Having solved the electrical irritation in the Diablo, I proceeded to changing the sticky exterior door handles (same problem as Ferraris) with some nicer CF laminated ones from MACarbon.

 

After getting the first one inserted, though, I found a problem. The door handles are plastic. Molded into them are threaded metal inserts which take a 10mm bolt to secure them to the door when installed. When Lambo or their supplier molded the replacements, they got a lot of plastic into the inserts. I can see the threads and a little metal, but their diameter has shrunk way too much to get the original bolts into.

 

I tried scraping the insides with a sharp right angle tool to "clean" out the plastic, but the plastic is quite hard. I'm agraid to get more aggressive as I don't want to damage the underlying threads.

 

I suppose I could get a metric tap/die set and do it that way, but I'm still concerned about cross-threading the existing insert, or worse, breaking it loose in the plastic so it just spins, ruining the expensive part.

 

Any other ideas? I've contacted MACarbon but I don't think it was their fault - I think they got them this way.

 

Thanks!
