I am struggling a bit with Photobucket, that is why three posts.
This is my two parts top form. For me it is easier to put in place.
When the lams and riser is in place I put on a clamp to stop riser from sliding. Then I have made a rounded block of wood that fit over the clamp jaw, the air hose rides on top of this. When the hose is inflated I remove the clamp. The riser in the pic is just to show what I mean. The rounded block also helps against air hose pushing on lamination ends. Bue--. Smart a-- moron.
