I have been slowly laying mdf floorboarding down in Bev’s loft. I had to start by making work space by cutting each board to fit the unevenly spaced joists, but now I want to butt join the boards which will be supported either side, between the joists (thus saving about a quarter of every board).

I cannot find double ended nails that I can lay my hands on, and I doubt that I could drill exactly positioned and perfectly perpendicular holes for rowels, so double mortise and separate biscuit(?) tenons seem the best bet. As long as I can cut the mortise hole well enough I can make them over long, lay the first board, glue the tenons and put the next board in straight away, and know that the tenons can move as I hammer the board home to the already laid ones at the end and side.

Sorry about the long winded intro. but you need to know the job before I explain why the Dremel 4000 – 50 is so shit.

The Dremel 4000 is a ‘rotary power tool’, which means it is a small sized electric drill, albeit with a lot of power for the size. It claims to do many things and cost a bit under £100 and came/comes with 50 accessories. I needed sometime to take a small amount of wood off the edges of a frame. I spent a long time checking the reviews and reading the specs before buying.


The literature, listings and on-line support is utterly abysmal. It is impossible to know what the things inside the box will, and will not do, until you try it. It tells you some of the things you can do with it, but there is no list of possible jobs on the box, on-line, or in the manual and you have to cross reference the list of included accessories that only appears on the box (not on-line) with a separate, vast, full accessory list to find out what things do; and if you do not have the box (like me now) you cannot even be sure you have not lost something.


It sold with nothing to cut or shape wood with! It has general ‘cutting’ blades but they are basically made of very hard sandpaper which will set fire to your wood and wear out. I did use it to cut metal plaster beading to make a pylon shaped picture frame with, but had to finish that job with a hacksaw when all the discs wore out.

That means I could cut mortises with it if I bought a cutting bit for £7, especially if I bought the £25 router kit to go with it; but Wickes are selling a proper router for only £37 which will do what it says on the box, instead of promising to change my world in many unspecified workshop ways.

Straight out of the box the Dremel 4000 – 50 is good for engraving, polishing and sharpening. It is useless for any kind of wood working without buying extra bits, and while it will cut metal with the toughest blades, it will not cut much before you have to buy a new blade.
