The replacement frame had decent tenax stud threaded holes, except for the left outside one. It would not tighten up. Notice this time around I am taking nothing for granted! Here I ground the chrome off, exposing the base brass of the frame. I was going to weld the hole closed with brass...but fortuneatly wised up at the last minute. If I heated this frame enough to weld, it would drip away to nothing! I chose to silver solder the hole closed. I then ground the solder flat, drilled a fresh hole, and re-tapped the hole with a 2BA tap. Here is the resulting "new" threaded hole, ready to go to the chromer.
I sweet talked the chromer into finishing my replacement surround frame in 2 days! I normally have to wait 2 months. With a sob story of what I've been through, and an offer for an extra tip...he chromed the frame in record time! I have to remember this stroke of luck next time I'm on the down swing. I have to remember it always swings both ways!
In this pic you can see the same hole that I repaired in the first pic. Just like new! Gotta love chrome.
Not taking any more chances, I ran the lubricated 2BA tap through all the stud holes. I am not going to cinch the studs down, and will use permanent thread locker to ensure they stay in place...forever!
As a trick to prevent scratching the new chrome, I am using a slightly larger metric socket over a paper towel to tighten the studs down.
We are doing the studs now so we can check the depth they are going through the frame. They should go no farther through than the thickness of the welting...rouhgly less than 1/16". If you are worried, use a dremel cutoff disc to take off the end.
Note: You can see the latest version of tenax studs have a slight teardrop shape. It is not OEM shape, and I am sensing that soon this will be the only style available. I learned they are a HUGE improvement if you can stand the slight difference. The tapered end allows you to simply press the fasteners on, and they click locked! The OEM requires you to pull the tenax release to get it to open up and accept the stud. If you insist on the OEM round tenax, I suggest you find them now, as I think they are going to be NLA soon!
Here is the frame all "studded" out. Finally!
This is the nut plate that must now be installed in the glass channel of the surround frame. It is what the stanchions screw into, and if you forget to install it you will have to remove the glass when you discover it. VERY IMPORTANT!
Of note, the early cars use this one piece nut plate, while the later frames use 2 separate nut plates. The one piece can be used in either frame. The 2 piece will not fit the early frame unless you drill an extra hole for the locating screw.
These plates accept the upper 2 stanchion screws. The lower angle plate accepts the bottom stanchions screw.
Here is the plate inside the glass channel slot. A screw from the outside holds the nut plate in its proper location. We are now ready to install the frame to the glass.
There are 2 types of welting. Moss sells a normal rubber welting. By normal, I mean it can be stretched to make it thinner if need be. Here I am using the TRF welting, which is made from a butyl rubber. The butyl (and I am sure I am mis-spelling that word) will stretch a little, but unlike the standard rubber welting, it will tear if you attempt to stretch it to much. This welting is almost like a tar strip, and will squeeze to the thickness needed.
Note: If you are using the real rubber welting from Moss, use some sort of soap or silicone lubricant on the welting to aid installation. The TRF butyl welting needs no lubricant.
In the pic I have used clamps on the bottom corners of the glass, and I have wrapped the welting around the bare glass edge.
Now set the glass on the bottom edge and place the surround frame centered on it. Work the top edge of the glass into the channel in the frame.
Now we go back to the rubber mallet and whack along the top of the frame until it seats fully down. You will hear a different, more solid sound, once the glass hits the bottom of the channel. Once the top is good, turn the glass on one end and hammer the other end into the channel. For the ends, I set the other end on a towel on the shop floor as I hit the upper end. Then reverse.
Here we have worked the glass well into the channel, and only a small gap remains at the lower corners. We need to stop at this point for a minute, to install the upper seal.
Unlike the bottom seal, which is too fat to slide well, the upper seal MUST be slid into place. You must start at the bottom corner, inserting the seal into the seal groove. Work the seal on around the groove until it centers at the top of the surround frame. You must install the seal now, as once you secure the surround frame to the lower frame the slot will be covered.
Now we can join the bottom corners of the frames. Here I am using a knife to trim the welting even with the frame. Notice the metal angle tab is moving up and into the surround frame glass channel.
Tap the frames into each other with the rubber mallet, and then install the 2 locking screws through the surround and into the steel angle bracket. There are 3 holes in the bracket and frame. You MUST use the upper two holes for these locking screws. The lower hole is reserved for the stanchion screw.
Once the frames are joined, We now trim around the frame with a sharp knife and remove the extra welting.
So here we are...glass installed in the frame. Hooyah! Still more to do, but we have finished the hard part.
To make room for the stanchions you will need to slice the lips of the lower seals even with the edge of the frame. This will allow the seal to be moved out of the way of the stanchions.
This sequence is to show the parts and their orientation. Notice there are 2 short and 1 long screw. It is essential the long screw goes at the bottom. Notice the bottom hole in the stanchion has more meat, so the bottom screw still extends the same distance into the frame as the top 2. If you accidentally install the long screw in the upper holes, you run the risk of hitting the glass and starting a crack.
Also, at this point do not tighten the screws, merely get them started...because...
The top seal must be trimmed to match the top of the stanchion on each side. Then, the edge of the seal gets located UNDER the tenon plate. The tenon plate anchors the ends of the seal. Once the seal is captured under the tenon plate, you can snug the 3 stanchion screws. No need to over tighten these! Snug is good.
