    Ordering inserts and parts for tooling The online catalogs are less than good.

    I am trying to order some shim seats for a Valenite boring bar. The number on the bar is 920U or S20U MCLNR-4 NL-44 CN-43. I cannot find anything in their catalog listing this bar. I have a bunch of seats but the hole in the seat is too big for the screw. I am having a bad day. :cryin: John

    Companys on the internet that don't give their location.

    Every time I look for a supplier or machining company on the internet they don't list their location or you have to hunt for it. Not a good business practice in my estimation. With them listing only an 800 number there is no way to see if they are in a reasonable distance from my shop. John
