Replacing Odyssey 8 Focuser

I am buying an Odyssey 8 4.5 but it has the dreadful pushpull focuser.

I would like to replace it with a rack and pinion focuser. Being that this would be my first telescope making project and I have very little practical experience modifying scopes, what are the potential pitfalls and what do I need to be mindful of?

Is it as easy as buying a R&P focuser and "throwing" it on? Or is it more complicated than that? I suspect it is but wanted to ask first.

Hi Zach
I am assuming that you have the old push-pull pvc focuser thats glued into the tube. Thats what my Odyssey 10 inch had. What I did was to buy a helical adapter from Lumicon thats screws on to the fitting thats attached to the tube. Just unscrew the old pvc pipe fitting and screw this one on. I've replaced it with a JMI reverse crayford the other day and still have the Lumicon adapter that I was going to put up here on AM, but if you are interested, drop me a line.
