Hi All
Well i have decided to build my GH Thomas tapping stand. i have had the castings for several months.
Today i have managed to start the table, smoothed off the casting and used the DRO for the holes. the holes need drilling and milling into slots. Its not as grainey as it appears

and cleaned off the arm faces

not much but its a start.

I have one complete but have never got 'roundtoit' to make the drill assembly and
hope that you have got George Thomas's Workshop Techniques book to assist in the build.
Presently, I'm adding bits to his small Dividing Head which also features there.
May I wish you happy building such a quality item?

Hi,
Fergus, yes i have his book, its a great resource
Well a little progress, i now have a table with the slots.
did the first 4 slots with the aid of the DRO, then rotated it 45d on the swivel vice for the last 4.

Nice work, I have to ask where did you by the casting from? :nrocks: :nrocks: :nrocks:

I hope that Pee Wee will forgive me by adding a bit of history to complement and compliment his excellent worksmanship.
Of interest, there are actually two sets of castings! They are described in the original G H Thomas book 'Building the Universal Pillar Tool' Actually I have a copy which I bought before GHT died. He also produced one called 'Dividing and Graduating'.
This- and mine are the Mark 2 version after some workers found the original arms closed up after splitting to form a clamp!
Of course, the write up appeared in Model Engineer prior to going to print as a book. It prompted someworkers to make fabricated ones by welding and another of my friends made up one from solid steel sections. It was exhibited on a Club stand at an exhibition.
Actually, I bought a welded one- prior to making up mine.
However, there is rather odd turn up. Several workers of a past generation saw the merits of the tool but couldn't afford the kit of castings etc.
Consequently, they salvaged connecting rods from BMC A Series engines( the old Minis, A30's etc) and used them as the mark 1 arms and saved a lot of work.

Hi Saw,
the castings are from here http://www.hemingwaykits.com/acatalog/Universal_Pillar_Tool.html so far i can not complain about them at all. other than getting everything covered in black dust getting through the crust. :D
Fergus,
nothing to forgive, feel free to post anything in the thread. its always good to learn about the history and variants of a project. intresting about the A Series con rods as Classic mini's is another hobby of mine.
