Johny No Mates needs a little support

Hi Folks

Thanks to all the support from Forum Members my skills have advanced sufficiently for me to have completed all the sheet metal drawings needed for despatch to the laser cutter/folder firms.  However, for my own amusement I have delved into Assembly and the Black Art of Mates.  So far it has been possible to assemble in more or less the right positions all of the parts.  However, there is one assembly that would be nice to generate in 3D even though the drawing is not essential to the project.

Essentially it is the sheet metal grate with all of its extra support parts and the ash pan assembled into one product.  The grate stands on four inverted M10 X 75mm machine screws.  At the very bottom next to the heads of the screws is the ash pan.  That is not too difficult to do as it was well covered in the OS Standard Content blog.  Above that the four screws have a nut on which sits a length of 12mm X 3mm bar whose purpose is to stop the grate sagging.  Further up there is another set of nuts which provide the support on which the sheet metal grate sits.  Above the grate comes a further set of nuts which lock the sheet metal into position.  No problem in the real world, but nigh on impossible for the newby darughtsman with only a passing understanding of Mates.

 

Thus if anybody could be so kind as to explain how to lock loose nuts into position part way along a long bolt I would be most grateful.  For those who wish to see my efforts so far, the drawing is at:

Many thanks.

If I understand what you're trying to do, just add a fasten mate then click the offset box and offset the nut the desired distance.

Good luck!

Hi and Good Morning from a very wet Cymru

Many thanks for your suggestion.  I shall put it to use this morning!  As ever, it is a nice simple solution and one of those "Why didn't I think of that!" moments.

Thanks also for the link.  I keep using the Help section which is probably daft.  The courses are much better.

Best wishes

Pete
