2D drawing swivel castor

Hi there,

To practice, I've modeled a swivel castor and made a 2D-drawing for it. I chose 3 fits:

* An interference fit H8/n7 for the bearing body in the frame

* clearance fit H7/g6 for the wheel to spin around the spindle

* Clearance fit H7/e8 so the frame can move

The tolerance range of the groove for the circlip:

Also, I need to place some shape and position tolerances and roughness parameters. Can somebody help me correct my drawing, see if my fits are correct and some tips to improve my drawing-skills in the future?

Thanks in advance!

Your technical questions are very specific, so unless there is someone here working in this industry it would be difficult to answer, it might take a while before you get an answer (especially this time of year). By the way welkom to CADTutor. The actual drawing looks quite good, if i could offer some constructive critisism though, the actual layout is a bit difficult to follow, the parts are dotted about where they best fit, but this makes it hard to see what is what, I would either change the layout (if needed a second sheet would be ok) or make the notes a lot clearer (or both) and I would look at changing the dim style, this is just personal preference (and each industry has it's own standards), but at the moment your dim lines are not distinguishable from the rest of the geometry, a different colour or line weight would make it easier to read, and adjusting the dim lines offset distance would give better visual results.

In terms of the drafting I would suggest labeling the drawings as to what they are....such as Plan, Elevation or Section. I am not familiar with the drawing, so am unclear to what I am looking at. Maybe some notes too to explain the drawing. A big part of drafting anything is to communicate something. And I'm not cler on what i am looking at.
