Some time ago, a user on here collimated his own Takahashi toa130, a feat most of us fear to do. He did it with a laser collimator. I think his user name was tempestwizz, though I now can't find the thread. It was more than 12 months ago and I can't search back further than that. Perhaps you'll have more luck. He'd be a worthwhile resource to consult.
Edit: here is the link. Hope it helps you.
