Stainless steel door frames

Post by woomera » Sat Aug 03, 2019 1:06 pm

Hi all,

Can anybody advise if these are still available? I understand the person who originally made the stainless steel frames had stopped and someone else had picked up the baton, but I’ve heard nothing more recently.

My original frames are in a bit of a state now and I am quite urgently looking for replacements (If anyone has good condition original frames they are willing to sell I would be interested in that option also).

Cheers,
Graham

Not made ta present but there is queue building - club traders probably still have mild steel ones for sale - not cheap but there is no other option just yet.

Mine also would benefit from replacement, if anyone is building a list of potential buyers...

Stainless steel door frames

Having spoken to Mark Wilson about this (with Peter!) at Silverstone the main issues are the machinery to fold the bend at the top of the A post and the fact that almost every set of door frames needs considerable "fettling" to fit.

Mark will correct me if I am wrong but even if he got the machinery to form the bend then he is reluctant to produce them because of the difficulty of fitting these. They are definitely not a case of "Haynes - refitting is the reverse of removal". He had such a hassle with doors on MB42 when trying to fit a good used frame that I think he is blocking anything to do with door frames from his memory!! :)

However, if we all speak nicely to him........... :wink:

Has anyone rung round and found any NOS ?. :?:
I seem to remember a tale that was circulating that GW had a batch made years ago, but the fit was terrible and not very good. :w

Not had a reply from the Gent whom we think has some jigs/pokery from the original batch produced. :(


I still have One excellent Passenger side to use as a pattern if I can overcome the bending problems on the front edge. :(

Sleepless nights IF I make the investment on these.

The window channels WILL need gluing in, unless I can Hatch a cunning plan to retain them. :wink:

Stainless steel door frames

Post by drcdb15 » Sun Aug 04, 2019 5:35 pm

Does it have to be stainless steel? Could an aluminium alloy be used ? These extrusions are produced in huge variety, and presumably forming to the curve of the door would be easier than with steel.

Is Dave Speed there? He did if I understood him correctly some bespoke fitting of the (original) door frame to one door of my car recently. Any views on the feasibility of this, Dave?

From my own (extremely limited) experience of trying to optimise the frame fit, the frame doesn't have any structural function, does it? It just has to stop the glass flapping about and hold it reasonably snugly against the weatherseal.

Alloy does not like bending, or welding for that matter. :w

I know the MB, or most of them, do not have the embellishers on the top of the bumper mouldings, but these are a pain int arse to keep looking good without being Anodised.
Some years ago I sent a few sets of these "Fancy trims" to a local company for re polishing and anodising, after they said " NO PROBLEM", they stripped back the parts then gave me a bill for £75 and said " NO THANKS" can`t be done.

The door frames are also cosmetic too, and Must follow the curve of the aperture and LOOK right without hitting the top rain gutter( Also anodised Alloy ).
We looked at the cars at Silverstone and most of them had un happy fits and shut lines. :shock:

If joining alloy is a problem then why not use a structural adhesive that is cured with heat , as we do at work and the aircraft industry

What is this interesting product called?
Could possibly be useful for work.

Sika 497/3 or 489

The aircraft industry uses other types.
All need heat to cure

Bloody good glue if it can bond 0.8 mm to 0.8 mm as good as welding, which is a "Mechanical" joint rather than a "Bonded" joint :?

0.08mm hmmm 3 thousand of an inch that is thin. So just as thick as cigarette paper?

Yep. Some people think the rivets used at the same time are the strength - they’re just used to keep the panels in place whilst the adhesive cures..

Never try and argue with an idiot. They drag you down to their level, then beat you based on experience.

I recall Dave Green fitting new to his GTC, took him a good 8 hours a side, never again he said!


SE4c rebuilding. SE5a similar it seems!
