Not from these people, bought mine from the UK from Corbel Welding but they are only box shifters.

....The fillet welds are not structural  just me faffing about , the parts were welded all the way through from the other side ,after welding the parts up  i was not happy with the look of the square internal corners so i decided to tart the job up a bit  :loco: .......

No Rob, that's not the correct terminology - the fillets were balancing welds!

Hi Lads


A bit more progress today on the angle plate ,,machined up the long leg of the angle .



I still have to machine the radius on the short leg and a couple of chamfers here and there .


Made a start on the Keats angle plate ,,,,,,, marked out the cutter  centre end points of the slot pattern .


Using the centre finder the angle plate was adjusted so the two end points of the slot to be machined  were parallel with the travel of the mill table and the table stops locked .

 


Next onto the shaper to have the top face machined ,, there is a bit of twist on this ,, but it should machine up OK
The Keats was bolted to another angle plate roughly in position , set level to zero on the shaper box


Then the level was placed in the Vee and the two screw jacks adjusted until the level read 45 deg.

top face machined  up .

Not happy with the finish ,, there is a hard spot that kept killing my tool ,,,,,,, quick lash with the surface grinder should fix that  :dremel:

Rob

I think this is the first time I've actually seen machinist's jacks used in a real setup!  So they do have a purpose other than just a "first project"!

It would be a shame to paint those and cover up all that lovely work. While you obviously can't judge any weld penetration by eye. Due to my job, I've looked at many 10s of thousands of welds. Pretty well none of them looked as good as those do. Awesome work as usuall Rob. :beer:

Rob,

I think you must have a very special digital camera with 'Shiny Metal' and 'Smooth Fillet' settings - brilliant.

Thanks for all your comments Lads  :beer:

Just about finished off  machining the the body of the Keats today ,, cut a slot in the bottom of the Vee .


Set the job up at 45deg so that i could machine one of the Vee faces .


The job was then rotated and the machined face clocked in vertically and the other face then machined .

Job done , just have to decide weather to machine the off two sharp corners , either to  radius or chamfer them



I still have the clamp bar to make  :dremel:

Cheers Arnold and John  :beer:

Call again John when your next up  :thumbup:

Finished of the Keats today  :dremel:  ,,, machined a 11/16" rad on the angle plate and the ends of the clamp . My box angle plate came in handy .


I decided to slot the clamp bar ,, so that i would get a better range of parts that Keats would hold . I also only machined were needed on this part , no need to machine it all over .


Next the Keats was mounted on a turned length of bar in the CUB lathe so that the back face could be turned true .


Job done  :)


Suppose i better get on with what i was originally doing in this thread ,,,,,,, if i can remember what that was  :scratch:


Cheers Rob
