    You need a rubber wheel of desired grit. It'll produce a perfect mirror finish (limited by your machine). Alternatively, you can hand lap with a lead lap and adjust the stroke length to end up with a...

    I heard of Krupp making some large steel casting for an exhibition - I think it was a couple of tons and around 1850. Casting steel though must be ( for small quantities ) MUCH, MUCH ! erlier. I have...

    Sorry ! I forgot to press the right button and reply. Once more :) :

    There is little CNC here compared with the US and that mainly because there is VERY little quantity production. Practically all...

    I (we..) do ONLY manual equipment. We are waiting for this Covid thing to start fading away a bit as not much in the way of vaccinations happens here :) and will probably create a web site with...

    We would like very much to do something especially about alignment, lathes in particular as I think this will interest most people. We need to find a suitable form for doing that and we are...

    I wasn't thinking specifically to cyl grinding but in general. Quite a few milling machines can drop as low as 2mm/min.

    Thank you for the kind words. Posting pictures of complete machines is out of the question as they do not belong to us but what I can do is post pictures of various work stages on isolated machine...

    Bicycles with that "feature" don't live long enough to matter.

    I think you should follow torque setting where it matters. Cars, trucks , a/planes etc. Bikes, I don't know. The torque is intended to bring the screw to a certain tension.
  14. That is a COMPLETE waste of time. Once the late...

    That is a COMPLETE waste of time. Once the late is back together you need to check the compound moves perfectly parallel to the carriage and the spindle. That is very important.
  15. That's DIRT getting past the wipers and then...

    That's DIRT getting past the wipers and then under the carriage ways because gibs were not adjusted properly. Clean it well with a small STEEL "toothbrush" , blow with compressed air and leave it as...

    Wonderful skill, effort and dedication ! Please keep 'em coming - it's a joy to watch.

    You are missing the anchoring bit for the collet opining handle. No idea for that machine, you'll need to phone / email around to get a pic. It's a useful system and the collets have decent range but...

    Looks to me like that too but it's not impossible that some lack of lubrication coexisted. That the wipers "squeege" all the oil is relevant only if they do that with the front lip. Otherwise, they...

    No, that is a standard 12 tooth gear on a standard rack. You can actually buy just the gear, turn off the old one and braze the new one in it's place. Bit of a botch but it works and it's cheap....

    I haven't bought in a couple of years but they were around $500 for the set - not that bad compared with others. I always found them clean, i.e. not contaminated but with a fair amount of dings and...

    @ OP

    Paul : the best course of action is to clean the machine reasonably well and inspect what you can see. Learn how to adjust the gibs on the carriage - needs to be done well and the gibs in...

    There may be other reasons for the saddle rocking "like a rocking chair". One needs to eliminate ALL the other possible causes, first.

    The OP's lathe seems in decent condition. That particular...
