I finally got around to modifying this elegant light weight plastic chinrest to the Wiplstix. It is made by the good folks at Magicfluke who also make portable instruments including violins. Though it does not fit inside the tube like the inflatable chinrest, it can be removed easily for travelling and the chinrest is taken apart for consolidation. The manfacturer emphasizes that a washer be used to distribute the pressure and that it isnt too tight for fear of cracking the plastic. The joint where the screw attaches it to the fiddle allows for a good amount of adjustment for a comfortable, personal fit. I am delighted to add this as an option to the wiplstix to accommodate those who need a more classical chinrest.
wipLstix are very handy travel violins invented and made by me in my shop in the southern Appalachians. The length between its bridge and nut is that of a standard violin, but the body has been minimized to maximize portability. wipLstix is a self contained unit, complete with its 1/8th size bow and inflatable chinrest, all fitting inside a 2" diameter by 24" long watertight traveling tube! The case will also nicely accommodate the chunk of round rosin of your choice.
