I found the videos very helpful
Greg Lis Robert & The Team
My project was not door replacement, rather the construction of a simple tall cupboard to enclose my central heating boiler and to provide storage for brooms, mops vacuum cleaner etc. Although the cost was rather more than I had in the budget . I am delighted with the result. I enclose photos which do not really do justice to the subject due to my limited photographic skill and equipment.

and also I was glad to have had your recommendation to use four hinges on what is quite a heavy door. In the interest of trying to be constructive rather than merely critical, I think that it would be helpful to include in the videos some guidance on the choice of screws for use in MDF. In particular I would question the suggestion to use standard #6 3/8" tapered woodscrews for fixing hinges to doors, since in my experience this would risk de-lamination of the board. I would prefer a longer, parallel screw in a pilot hole.

The screws that we suggested for your hinges are the same ones that we have been using for 15 years when fitting doors ourselves, so I can assure you that they are the right ones for the job and that you'll have no problems using them
Best of luck!
