MG MGB Technical - I'm gonna do it....

Yes, the dreaded windshield. Despite the warnings from everyone here, I've decided to try to replace my windshield glass myself. Cross your fingers and wish me well......

Ken,

Best of luck to ya. Why don't you take a lot of pictures and document this experience as well as you can. I'm sure that a lot of other people would be interested in the whole process especially if they can see some pictures of what you've done.

Once again, Good luck - Dennis

Have fun, Ken.

I just did mine on my '74 as well as a new dash. I never did either when I restored the car in '98.

One thing I did change was the Philips/posi-torque screws that hold the frame together with Robertson-head screws. Being Canadian, I know you'll know what those are.

I did this on my V8 project. You can get Robertson counter-sunk screws in the correct length for the outside top screws and the shorter ones I just took them to the grinder after measuring the originals with a digital caliper.

Cheers

I made use of a couple ratchet straps (for holding down cargo) to hold the frame together while aligning things. You may find it handy!
Good luck!
May the Force be with you!

I am with Simon on the replacing of the screws. I prefer the allen head ones myself as they do not have a torque limiting taper built in to the drive mechanism. Also, I am not aware of any high grade robertson fasteners on the market. Simon, not only from Canada, but from worked in Milton Ontario, home of the Robertson fastener!

Good Luck, I've never done a B but done numerous midgets and can vouch that the use of luggage straps and ratchets help immensely. However my one word of caution is to check the length of the screws or fasteners that hold the frame together. I did one Midget screen and the screw touched the rim of the glass screen, resulting in one craked screen less than a week after installing it.... ouch that hurt the wallet.

Patience is another key to success.

Hi,

Was this thread about a roadster?

Hi
My dad used to build MG's and a friend of his worked on the windscreens and reckons he can replace the glass in situ! Not so sure anyone done this before?

Graham,

If what your dad's friend is true, he could be everyone's hero!

Too right, Pete. I watched a program on the Discovery Channel about the history of the Robertson screw & driver. Even had the American contractors singing it's praises. My wife couldn't figure out why I would watch a show about screwdrivers.

Make sure you mark and align the centre of glass, top frame, bottom frame. Do this to at least within a mm. If you get it exactly centred (I did the last/second time I did it)it will actually be easy and only take a couple of hours!.Beware- The centre strut/rearview mirror placement is missleading, it is not necessaraly centred. I found this out the first time I did a windscreen and it took about 12 hours!
I wrapped strong cords/ropes around the screen (off my catamaran)and tightend them by winding big screwdrivers in the rope. A rope at each end, two in one direction, two in the other. For the horrizontal cords you need to place a length of wood on the outside of the windscreen, centre, and hook the inside half of the horizontal cords over the bit of wood top and bottom. Otherwise you fold your windscreen in two when you tighten things up.
Last and most importantly, have powerful refreshments standing by.
