Thanks Paul & Kev
Kev -
1 - I could have used MRMDF throughout, just the customers preference for hardwood for the face frames and doors.
2 - Yes, cut back with some 240 after each coat.
3 - You could use a dado cutter to create grooves - that would be stronger than biscuits. Still reinforce with screws though (saves on clamps whilst glue is going off).
Next WIP - a small TV cabinet, but then I think i've got another one of these kitchens to make - I have shown it to a customer who wanted a freestanding kitchen building, and they loved it. I think theirs is going to be in solid oak, ie no paint. Probably use veneered MDF cabinets.
Any other questions, just shout.
Cheers
Karl
