I'm building up a Teledyne Titan. It uses an english threaded bottom bracket. I just received in the mail a pair of "thin" BB cups. With the spindle I have, 70-SS, there is too much play when the cups are tightened. Do I need "thick" cups? The problem is either cups that are too thin or a spindle with races not far enough apart. Can any Teledyne experts tell me which is the required combination of cups and spindle. Thanks, Rod Handsfield Las Vegas
