Hello Onshapers I am struggling to build a simulation model of a link type steam engine valve gear

I come from an engineering back ground but not CAD  I am building a 1/6th scale model Ploughing engine &  to date I have used Onshape to produce 3D metal parts and 2 D cut outs
Making the mechanism link has escaped me
I am really a dabbler in the public domain  Gill Tetley   model is called valve events
Although I have watched Neil Cooke numerous times         I am miles away from sorting this  keen to discuss any help greatly appreciated
regards g

    Hi and welcome.  We'd need a bit more to go on to be able to offer any real suggestions.

    The best way is usually to post a link to the file onshape document you've hit a roadblock on, and maybe add a rough as you like back of napkin sketch of what you're after.  A picture speaks a thousand works here.

    Thanks Owen Appreciate your interest 
    I am not certain how to post
    The design is basically a slider crank  the rod has an offset that rides in a curved link that can pivots to change orientation the end drives a link connected to a bell crank which drives another link to the valve.  now to fins a link
