Welcome  This website is a personal view about designing and making models/tools in a home workshop.  Hopefully, the content of this site will inspire or encourage anyone to create something they can be proud of.   Engineering in a home workshop is usually about making models but for me I especially enjoy the creative aspect of engineering.  The making of the  gear generating machine (see Making Gears) is a good example as the end result is a totally unique machine created from only a brief outline description of the Sunderland gear operating concept and thereafter a substantial amount of experimentation..  The content, advice and opinions within these web pages are those of the author.  As such it is entirely the readers responsibility should they wish to follow or adopt the information herein.  Please be aware that workshop equipment can be dangerous if not used with care and due regard  of safety equipment and procedures.

And yet another change made to improve the BH600G. On inspection of the leadscrew no provision is made to eliminate any end play that might exist.  The solution was to make a short extension to the leadscrew at the tailstock end and using two needle roller thrust bearings in appropriate collars.  The collars and bearing sets are assembled either side of the existing leadscrew bearing block and end play is eliminated by a nut which applies a very light amount of pre-load.  Although the amount of leadscrew end movement was quite small this can badly affect the true pitch when machining threads especially very fine threads.  This modification is a couple of hours work and solves the problem completely.  This approach is on more expensive lathes as standard though sometimes just using plain bearing seats.
