help in selecting drawers' mechanisms

[vas]

hope I got the apostrophe right...

OK, my ex chart table new design includes a massive drawer 800mm wide, 600 deep and almost 300mm high. This needs to slide on the chart table on the bow-aft axis making it rather sensitive on the way especially with the nose coming up on the plane.
A couple of rounds of questions on specialized shops and checking online catalogues haven't prove v. helpful.

I'm stuck with blum's offering Tandem mechanisms with some odd and impossible to understand "locks" that seem to allow the drawer to open for an inch or two before you release the lock.
Same goes with hettich...

Now, my 30yo original drawers (restored and reused all of them) where wood on wood with simple blocks of wood and grooves meaning that in order to "open" the drawer you had to lift up and then slide. Cannot apply this technique on a 20odd kg drawer, so I'm asking HOW the heck do modern boat drawers work???
Unfortunatelly the P45 and P412 I have easy access to are too old for fancy high tech mechanisms (and drawers are tiny anyway...)

Next to this drawer I've got a cabinet that has a folding/opening/whatever lid. Basically access is from the top. Thought hard on my options eventually came across the blum aventos series that works impressively well for vertical doors but I'm not sure how they'll function on horizontal. Any ideas on that also welcomed.

cheers

Obviously anything designed for a kitchen is going to rust on a boat. Make up some stainless steel runners fixed on the cabinet sides and nylon wheels also mounted in S/S on the drawer. Then use the locker catch of your choice to keep it shut.

My drawers use a mechanism like this:

I also have fore-aft drawers, admittedly not with 20kg in them - but these catches haven't failed yet, in six seasons of cruising, including a memorably bouncy ride through the Alderney race.

Clearly wooden runners will be the most reliable Vas, but not necessarily have the smoothest action. I would not be against using kitchen drawer runners in your application, as you probably don't get the high humidity we get through the Brisitsh winter, so I can't really see why they would rust in your boat much more quickly than a British kitchen, which also suffers high humidity from cooking.

thanks J.

hadn't thought of using cabinet door catches in this case!

I'm talking about decent quality blum mechanisms or hettich (both either galvanized steel or powder coated), I'm pretty sure they'll last long enough to justify their replacement in 5-6yrs

Vas,

You could take a look at drawers from Grass.
http://www.grass.at/uebersicht-nova-pro-deluxe.html?L=1

I'm used to work with this brand, simular to Blum or Hettich, but in my opinion a bit more sturdy. Availlable in different lenghts and height. Standard holds 40kg. But they do not have a sollution for locking.

To lock the drawers you can use the locks Jimmy the Builder has send.
I've been looking for other ways to lock for my own project, but in most cases you will need a seperate lock and handle. Unless you work with handleless fronts.

The aventos system from Blum is not usable I think. It's more ment for lifting doors.
Maybe you could use a gas spring, something like this?

In the Hafele catalog you can find more things like this...

Greets, Kristof.

Kristof,

thanks for the pointer (vaguely remember Grass and I'm not even sure there's someone importing them down here...)
Yes, looks like JTB push locks will have to be employed.

The aventos was mentioned for another cabinet in the area that needs to lift up in a complicated fashion.
Problem is that all these odd shapes are extremely difficult to properly design and check, so end up mocking things up (after a lot of sketching)
Will post tomorrow on the main rebuilt thread and it will be a bit more clear (I hope)

cheers

Agreed.
