I didnt want to continue the topic swap from the other post, so I have diverted it here! for those missing the beginning it starts from the link below. http://www.screwfix.com/talk/thread.jspa?threadID=79764&start=0&tstart=0 with bernieeccles asking me a question... feel free to update yourself. ========================================================= Lamello is correct, quality tools do help produce quality work, theres no doubt about it. My job in the firm I work for is more complex than the basic Masons Mitre, yes a quality Jig sharp cutter decent router will produce a very good finish that would only require a little tweak to produce a hairline for a join its not difficult. even someone with a poor quality jig and a sanding block can achieve the same join quality if they have the skill & understanding where to sand. I understand where Lamello is coming from... My reasons for colorfill are not the same as other peoples... My Job is laminated worktops, thats all I do. Inset postform returns in what ever style required, is what I'm employed to do, also other things but this isnt a cv or advertisment for the firm I work for. In its basic form, "its a section of postform cut from a donor worktop and glued into a cutout within another worktop", at what ever angle or situation required to suit the design of kitchen. there are no comercially avaliable jigs for a kitchen fitter to do this work. its the shaping sanding and fitting of the new sections which require lots of delicate work, even the best fit will require colorfill, for the best cosmetic enhancment. For me, silicone is usless in my requirements for joining the sections. Anyone who thinks they know better, has never glued thin sections of postform to another worktop ranging from 5cm in length upto and over 2 meters long or they would understand the benefits of Colorfill.
