Blum hinge and Tandem slide interference
« on: November 01, 2017, 09:17 AM »
I just installed some drawers that are hidden behind hinged doors.  The drawers use Blum Tandem slides, while the doors use Blum compact hinges.  I was suprised to find that there is a slight interference between them where the sides of the drawers rub against the adjustment screw of the hinge (see pic). Has anyone run into this before? I’m using 12mm ply for the drawers, and I thought this was a fairly common arrangement so I was suprised to have an issue with it. 

My only thoughts to fix it are to either grind down the head of the adjustment screw, or cut a dado in the side of the drawers to clear the screw.  Obviously neither of these is ideal.

I know nothing about these hinges I'm afraid, so I might be way off-track with this...

Could you rebate the side of the cabinet underneath the alignment screw slightly? (i.e. Just larger than the size of the screw.) You would then tighten the alignment screw further, allowing you to clear the drawer.

How much clearance do you need before you're clear?

    Is just the bottom drawer affected? 

   Quickest and easiest would be the dado, how deep?  Though not ideal appearance wise.

   Maybe you can recess the hinges a touch if it doesn't screw up the overlay, the opening clearances between door and face frame or the space for the wrap around mount.

   Take the drawer apart, make it narrower, shim slides out, or use undermount slides.

Typically in these cases I use a zero protrusion hinge and put the hinge fixture above, between or below the drawer and they do need room in front of the drawer. I am not sure how much space you have between the drawer and the hinge, so you will need to check the manufacturers specs.
Otherwise you other choices are as you have mentioned.
Good luck

Not that this really helps you now, but typically you'd use "billy blocks", plastic spacers that set the drawer slide off the cabinet wall by an inch so it clears any hinge.

I might be wrong but those drawer sides look 3/4 inch thick
Lot of those slides work best with 5/8 sides

Blum makes two different versions of some Tandem slides, an "F" and an "H".  If I remember correctly, the F is fat, for drawers sides over 5/8", and the H works for 1/2"-5/8" or their metric equivalents.  Their website has tons of well-drawn specs that call out the differences.

I make my rollouts 3/4" smaller than I would a drawer, solves this problem. I also make mine adjustable.

They may be 3/4" , but that's not what's causing the issue.

It's the overall design of the cabinet that's causing the issue.

If it were mine I'd just route out a groove on that drawer and hit it with a topcoat and call it done.  If it's for a customer, the drawer(s) need to be re-made or re- positioned in the carcass and the expense booked under " continuing education courses".

Could effect how deep a dado can be gotten away with. Doesn't look like it needs to be very deep though.

Thanks for the suggestions guys!

I only need a little bit of clearance so I think I'll try grinding down the screw head first, since that will be easiest and the hinges are cheap enough if it doesn't work.

They are 12mm (1/2") drawers so thats not the issue, however that does give me an idea.  These are 563H so they are good for 1/2" to 5/8" thick sides.  That should mean I can shim the slide on the hinge side out 1/8" and move the slide mounting clip on the drawer underside over as well.  That should be plenty of clearance.

The locking device may be adjustable.

You may need to slot the rear hole.

Do only the hinge side slide.

Take the screw out and shorten it instead, as it look like you have plenty of adjustment left.

Can't, the screw doesn't just push on the bracket behind it, its actually riveted in.

Looks like grinding the head down is your only real option.  [sad]
