Thread: Building a BIG desk

Geoff sorry for laughing but if memory serves me right you did similar some time ago its how we met. Something about buying an office chair and ending up with a truck load still I love my daughtsmans stools.

I see some fine cabinets with draws being made.

I know you did sagultor but a rail running along the front underneath from end to end and on the small return would make it stronger,say 50-60 deep X mm may add a bit to the "look"

There is a piece across the back about 200mm deep which, according to sagulator, will reduce sag significantly.
No room for anything at the front or it will be too low to get my legs under.

OK know what you mean

One thing you could do to reduce the risk of sag is to change the orientation of your corner support panels. By running them at 90 degrees to the back edge instead of parallel you reduce the unsupported span. This may mean reducing the panel size to suit the required leg clearance.

Reversing the corner support will lose me too much leg room in the corner. The computer screen will be across the corner and I'll sit into the corner to use it.
I'm going to have to trust the sagulator as all the bits are already cut to suit the original design.

Worst comes to worst, I'll put a steel leg at the junction of the top and return.

Another question, which I guess I should ask in the routing forum, is how to bullnose the desk edge.
I've done this before on a single piece of 25mm or 32mm MDF, in multiple passes to do top and bottom but I'm not sure how to do this around a corner i.e the inside between the main desk and the return.

Any pointers?

Did you figure it out?

You have measured from the top of the desk on one side, diagonally to the top of the cupboard on the other
A squared + B squared etc works out to 800.3905, or 800.4 between friends.

The best, but not easiest, solution is a masons mitre for the join. I found a site with a jig for the mitre so I'll give that a try, lots of spare bits to practice on.

Butt the tops together as if installed, secure, and do your routing

AS someone previously pointed out, the radius of the bullnose at the join will be different than the straight part. Not by much and it could be sanded out but a masons mitre will mean I just have to route the bullnose on straight pieces i.e. not around a bend.

ok sorry
how much is the jig worth?

Too damn much for a one off exercise! Cheapest I saw locally was around $199
I did get this link for building a jig from the routerforums.com site. It's in French but there's pictures
