If you peruse the Hemingway product description, you learn that it was designed by George Thomas. He somewhat pre-dated MEW.

Its description may have appeared in ME and you can search the online index to find the details.

It is also described in Thomas’ book.

The book Model Engineers Workshop Manual by GH Thomas has full drawings and instructions. Available from Tee Publishing.  It is a revised and edited version of the series of Model Engineer articles he did in the 1980s. Lots of other great stuff in the book too. Well worth having.

Hemmingway do comprehensive drawings and a copy of GHT’s instructions from the book. I’m just building a non retract version for GHT’s 4 way tool post to live on. Did the retracting one a while back. I have a new square style Myford top slide casting and have just made a gib strip for it. I modified GHT’s dowelling arrangement as I decided to omit the dimples for the adjusting screws. I fitted 2 dowels between the outer pairs of screws with the clamp screw in the middle pair. My thinking was that with the dowels the dimples really don’t serve much purpose and it’s a lot of faff to drill them through the existing threaded holes.

I find the major advantage of the project is the larger and lockable micrometer.

Have fun with making it.

After doing the top slide I found the new micrometer collar such a pleasure to use that I made the one for the cross slide as per GHT’s instructions, including the thrust washers. It’s a vast improvement over the original. It’s so much easier to use. It can be set with one hand, lock the screw with a 1/4 turn of the small lever on the right. half a turn CCW of the knurled knob at the front to unlock the collar, set the collar to “0” ( or whatever), re-lock the collar with the knurled knob, and release the screw lock. No more trying to hold the cross slide handle so it doesn’t move with one hand while you fight with the collar against the tensioning spring to set it with the other. I wouldn’t be without it.

As a bonus, being larger they are much easier to read, especially the top slide one.
