Bearing race fitting advice
So i've just taken delivery of a new frameset to build up over the winter months and was having a look at the headset assembly earlier today. The lower bearing race that fits onto the forks stops short of it's intended position by about half an inch. Some quick research has pointed me in the direction of a crown race seating tool, but i'm just wondering if anyone has any tips/advice on homemade tools or alternatives. Any advise would be greatly appreciated.
If i have to, i'll take to my LBS, but i have a bit of an issue asking them to work on something that i didn't buy from them, especially as they're a dealer for the frameset i bought.....i know what you're going to say, but i got it £600 cheaper and on 24 months 0%, which they don't offer.
