|Thread: Hemingway Dynamic Toolpost Grinder|
Last Saturday mornings initial hand work:-
Fettled the Inner Cover cast appeture (this is slightly out of position, but not enough to cause a problem). The two 3.2mm drills, are just acting as temporary aliignment dowels between the two covers and will be replaced once the covers are painted,
Then the Outer Cover (Removed the Logo, to make painting easier),
Followed by dressing the assembled covers,
There's a bit more work to do and some dinks to fill before painting. This will be done when all the remaining castings are machined.and finished to the same level.

I've had this kit for about 9 months and finally made a start on Jan 1st 2019.
First off the outer cover, clamped down lightly on 3 blocks, to machine the bosses.
After machining the bosses, the 3 blocks are clamped to the machine table and then the inverted cover stuck on to them with superglue
The joint face was then machined down to the drawing dimension, using 0.5mm/0.020" cuts and some breath holding
The inner cover was machined in a similar way, but no need for any superglue this time on the second face
As most of the holes in the inner cover are dimensioned using Polar Coordinates, I used the DRO functions for these and again to mill the radius slot.
This meant that (even though I have both a CNC mill and a 10" Rotary table for this manual mill) only the one setup was required.
More to come!

|Thread: Learning CAD with Alibre Atom3D|
This video should help you understand constraints (you may not have all the constraints in the video available to you in Atom though)
There's more videos here (Don't worry Alibre was Geomagic before it was re-aquired )
