Since this part seems to be NLA, could it be copied on a CNC machine and made from aluminum and then anodized in black? Just wondering. Other wise you would have to make a mold and then make them one at a time, right?

I wouldn't think so... maybe with a lot of programming and manually flipping it over and switching tools.

Looks like it'd be 3 pieces all machined. then TIG welded together, holes drilled. that'd be my easiest way of taking it on.

Too small. It loks like the top piece for the rear window channel in the doors to me.
The only cost effective way IMO would be molded out of plastic or high durometer urethane maybe.

Not sure about the CNC machine doing it, but it can be done as Chris mentioned with a compression mold.

My spare parts are buryed under 6' of ice block, so I won't be able to access them for at least another month.

i just bought a NOS one from AA. It was expensive at $24 but who else has them. I must admit I was happy with the service. I guess you saw the one on ebay that wnet for a lot and you never know what you are getting. I think it stated "New Old Stock, AS IS" The seems questionable IMHO. But I guess I am bitter as I keep getting burned using ebay.

I could cast a mold of the one I am getting if anyone knows what type of plastic would work to make the piece the correct density.

no go. it needs to be flexible. can't make it solid, it would break (or not work right, whichever is worse) ...

GPR can get them for you if you don't want the stigma of an AA order.....

For polyurethanes, see if any local companies sell Smooth-On products. http://smooth-on.com They might be able to tell you what compound would work best.

Posted by: wilchek Feb 14 2005, 09:42 PM

I will look into it. I will get my friend who does art sculpture for a living to try and cast the piece. He may know what plastics work best and if it is possible. The web site above is about 45 minutes from my house. That is the supplier he get all of his supplies through, kind of weird.

Any idea of the number of people who would be interested in the piece, and what the price point would need to be. The plastic without any mold costs or clean up would costs about 150.00 a gallon. I would need to sell at least 20 at 10 to recover my costs less my time and effort.

Posted by: Always Looking Feb 14 2005, 10:07 PM

$10 sounds reasonable. I would probably be in for a pair (are left and right the same?). Good luck.

Posted by: skline Feb 14 2005, 10:10 PM

I was bidding on those ones on Ebay last night. I had bid at the beginning but like I usually do, I bid again in the last 3 seconds and of course, there was no time to bid again. They went for $39.00 but it was for a pair. I should have bid $41.00 and I might have won. Oh well, I am going to look into molding some out of a uerethane and sell them for a little over what it costs to make each one. We are cheap people, we need cheap parts.

Posted by: skline Feb 14 2005, 10:12 PM

They are different for left and right. I do know that.

Posted by: McMark Feb 15 2005, 12:45 AM

I had a thread about this awhile back. Bruce (GWN7) said he could make them in plastic, but needs good samples to start with. If anyone will pony up, we can get them produced pretty quick.

Posted by: sj914 Feb 15 2005, 12:51 AM

If someone wants to have these made. I'm in for a pair.

Posted by: Gint Feb 15 2005, 07:42 AM

We just did this thread a few weeks ago.

Whoever can get 'em produced, I'm in for a pair of early units.

Mine are cracked, I would also be in for a pair. Thanks,

i need a pair, too. are there different versions depending on the year of the car?

Does anyone have a pic of that part on the car, I'm having a hard time visualizing where it should go, ot if I even have it on mine!

Posted by: wilchek Feb 15 2005, 11:58 AM

It looks like this. The driver side and passanger side are different. The passanger one is still easily obtained. I guess they don't break as much, due to less use of the window. I am not sure about the earlier ones (70-72). I think you can still get these fairly easy. Somehow the drivers door (73-76) ones are in short supply for a 30 year old car. I can only imagine what it will be like in 30 more years.

Would like a pair of the late model ones - think I would pay up to $20 each but 10 to 15 feels reasonable.

Posted by: SirAndy Feb 15 2005, 12:59 PM

yupp, i'd be in for a set of early ones ...

Andy

Posted by: 914MF Feb 15 2005, 01:06 PM

A set of late ones for me.

Posted by: Chris Julian Feb 15 2005, 01:18 PM

Add me to the list for a pair.

Chris

Posted by: skline Feb 15 2005, 01:20 PM

Since I didnt win those ones on Ebay, I dont have any to make new ones from so put me down for 2 sets for the 74's.

Posted by: McMark Feb 15 2005, 01:44 PM

Now we just need someone to let us rent them. Anyone want to earn some parts money renting out their door plastics for mold making?

I'm in for a pair if someone is so kind to make them.

Posted by: McMark Feb 15 2005, 11:14 PM

Aaron, are you offering?

Posted by: sj914 Feb 15 2005, 11:17 PM

I just looked on the bird site for the late ones and it's no longer listed as NLA. So i guess they found a stash somewhere.

You're right! I just ordered a set. We'll see if it's for real.

Posted by: sj914 Feb 16 2005, 01:25 AM

I ordered when I saw it, it says the right one ships in a week. I take it that was the one that was NLA for a while.

Posted by: McMark Feb 16 2005, 01:30 AM

The left was the NLA one. Presumably because the drivers side window gets more action.

Posted by: rhodyguy Feb 17 2005, 10:57 AM

gpr has a few sets for late model cars in stock.

what window winding system does it have? does it have door beams?

Posted by: McMark Feb 24 2005, 10:54 AM

I got my door end cap. Notice the singular form of cap. The left side is backordered. Surprise surprise. Cost me friggin $8 for the one I did get and $7.50 for the padded envelope and a visit from the guy in brown. Anyway, I'll send this end cap to Bruce and he can get a head start.

I wonder if someone inserted the piece into CAD software and then flipped it and then had once cut on a CNC machine. Maybe we could make a mold of that for repro plastic ones. Maybe I'm too far out in left field.

Posted by: skline Feb 24 2005, 10:59 AM

There was a good passenger side one on the parts car Clayton cut up the other day and it was an early door. I think I have a couple for the later doors but they are not new. I will see if I can come up with a set of both types, if I can, they can be used for making the molds.

Posted by: bd1308 Feb 24 2005, 11:32 AM

if somebody could get me dimensions for this part, I might be able to so a copy in SolidWorks, and then a teacher here has a few CNC machines at his place....all i need to do is either show him the CAD diagram or send it off to be machined out of whatever....

Posted by: wilchek Feb 28 2005, 04:12 PM

Anyone else find some new one for molds. I finally found a used 73+ drivers side and paid 20.00 for it. We will see what kind of shape it is in to make molds. If it is solid I will try and cast it and then clean it up by hand to get it right. I'll let you all know. I don't have the earlier ones and have not seen one yet so I don't know what it will take to make them. If someone could post a pic I could get a idea.

They sent me both sides at the same time. I guess they had a limited amount.

Remil, can we use them to take molds off of? If so, contact Bruce (GWN7).

To prolong parts availability. I'll be glad to.

Posted by: scotty b Feb 28 2005, 07:17 PM

I have a fairly good, early pass side, and a drivers that MAY be good enough if you need those.

Posted by: McMark Feb 28 2005, 10:58 PM

scotty_B!, can you take a picture of yours?

I'd really like to help make these parts happen. I think there's a real need for good replacements.

Posted by: scotty b Mar 2 2005, 05:47 PM

O.K. Mark I may have typed in haste. I took pics last night but they aren't as good as I rememberd. I have 3 more cars here and 5 more somewhere else as well as several doors so I'm going to see if I have anything better. I will also take these to my machinist Sat and see what he would charge to cut a pair out of aluminum or maybe plastic, then we would have good solid pieces to mold from., Anyway here is what I have right now

Count me in for a pair, 74.
Thanx

Posted by: GWN7 Mar 2 2005, 09:37 PM

Scott,

the missing bits on those might be replicated. They would have to be cleaned up (paint removed, ect) before trying to cast them. There would be fine lines where the missing bits were replaced and a slight difference in the shading on the new ones, but you would need a magnifying glass to see it. It would only bother a real CW.

Posted by: scotty b Mar 2 2005, 09:42 PM

That's why I was going to see if my machinist could cut a pair from aluminum or nylon, so we could have a good solid piece to use for casting. Never done this before but it sounds logical captain nannoo nannoo
