Depending on the machine,i think it could be as simple as unscrewing a few bolts underneath and setting it on a table!! Do you know why she wants to do it,is it so that she can take it back and forth to classes or something?? If so then she may have to do some more homework.Might be easier to try and find a used portable somewhere.JMO

She wants to make it easier to store. We live in FL where we have litte storage.

what does she plan to do with the desk?? Does she know that you can just fold the machine down,and then one end of the desk folds over it,so it's smaller.Then you can just set something on top of it and use it as a table or a place to set a plant.

My mother & I had the same Kenmore from 1970. She put hers in a desk and I had a carry case. Contact the manufacture or a repair shop and see if they make a carry case.
