I have found this on how to do it:

Could you recommend any other instructions on doing it? tips? know anyone in WA who's done it so can help? 
Thanks,

The orthogonality problems frighten most. It is a tedious job to do but if performed to correct the operation of the telescope it will make a "dog" into a precision instrument. You are too far away for me to fix it but I have done many telescopes and seen some very poor examples from Meade and also some near perfect.
I have a method I use that works but many people have their own methods and as long as orthogonality is achieved it does not matter how you do it.
I used to have a document on my web page on how I do this work but since geocities closed I do not have a web page. The document is 277 kb long so I do not know if it will attach but I will try. No it is too big I will zip it up into a zip file
The Milburn wedge to my knowledge is far superior to the Meade but it will not cure problems of fork flexure, azimuth bearing loading and orthtogonality as well as other problems assciated with polar mounting a fork type telelscope, particularly balance.
