Nice work on the stop nuts and I like the box too. Sometimes Michaels has some decent finds and looks like you found one of them :)

Do you have any GHT stuff left to build, you must have just about done the lot?

Thanks Bill, Hugh, Achim, Dave and Steve for looking and your nice comments.

Great stuff Don

Steve actually this table was one of the first casting I bought before I started the Dividing Attachment. Glad to have it almost completed. And no I don't have any more of GHT'S stuff left to build. I think I done quiet a bit of them. I will be building engines after I complete this one.  :cartwheel:

Hey dog, no it wasn't planned.  I wasn't paying attention to what I was doing. As for the UPT, you need to get you one you will have no regrets.

Ok back to finishing this table so I can get to making engines again. I started squaring off the riser plate and surfacing it. Then started making T Nuts. I decided to make two types and made the first ones to fit the slot and flush to the surface. The second nut I made the shank .375" and drilled and tapped .25 x28 TPI. Milled the flats to fit the .5"  x .25 slot. I got a few straps and .25" x 28 TPI all thread pieces.

This is the riser plated milling the sides square.

Finishing the surface off with a fly cutter.

I finished the riser plate by drilling the rotary table mounting holes to be tapped .25" x 28 TPI Then finished the T SLOT mounting holes to 17/64".

Then I started making the T Nuts and milling them to size.

I decided to slit the T Nuts off on the lathe.

I want some tubular T Nuts that way I could use a bigger stud and in this case .25" stud. I used .625" cold roll and cut it to a length of .6" down to .375". After which I moved it to the mill to cut the flats.
Milling a .065 flat on the .5" and .375" shank using a .1875" slot mill.

Returning it on the lathe to part off to .155" bottom flat.

Now were are ready to start using it. Here are the final photos.


This has really been a very satisfying project. I know I had some mishaps and some of which I have to live with, but it was a learning process and as long as I am happy with it, it will do.
Now it's time to start making engines.  :pinkelephant:

You know I'm picking on you. Darn nice piece. Now before you take off building an engine, there is still a Quorn grinder that can be built. As Dave says; "I'm just saying" :naughty:

Don looking good but I think you need to make yourself some more clamps.  In my experience of using mine I find the most useful to be the ones like Emco sell. Here are them in use:



To give you an idea of size: the fixing allen screws are M6. Some alternatives that I find useful:



Both are a good size when working on the 4" rotary table  ;)

Don,

Nice rotary table you have there!  As Jo says I've found getting some suitable clamps makes a big difference in how easy stuff is to set up on these small tables.

Don,
You have done a beautiful job on the rotary table.  You've got a mighty well equipped shop now I'd have to say!
Can't wait to see you put it all to use :)

Nice job again Don. I didn't realise that there were raising blocks.
