Blum undermount runners in solid wood case

[farimir]

Hi

Has anyone used Blum undermount runners on solid wood case?  How did you attach it to the sides of the case to allow for wood movement?  I am planning on drilling out some of the holes in the runners to make them elongated, but I am worried that they might rust or something (living close to the coast in South Africa).  Any advice or help would be appreciated.

Regards

Are you talking about full extension runners?  If so you can use the bracket that mounts on the back and the runners just slides in.You just need to  secure the front.Don't need to worry about movement.

Some of the holes on the slides are elongated. Use screws through these holes and you won't have a problem.

You may have to go to a bottom mount system if you are using Blum Tandem slides. They are full extension undermount.

Go to http://www.blum.com/us/en/02/30/55/index.php and then click on Tandem bottom mount.

If you are not using Tandems maybe call Blum and ask what they suggest in your situation, I've always found them very helpful.

Wood will not expand/contract along the grain... it should be fine.

Oh.. I guess you where talking about the cabinet case? then yes you will have a problem.
machine a sliding dovetail, then insert a piece of wood in the slot, but only attach it with ONE screw at the front, then mount the drawer guide to the dovetailed piece.

I am planning to build a bedroom dresser for a customer who wants these runners and solid wood custruction. My thoughts are to either use metal brackets that mount to the back of cabinet, which will be 1/2" ply. Or I will cut thru the metal web between two holes in the middle and back group mounting holes and place screw in middle to allow for movement.

All of the custom caninets that I install have the Blum slides attached to the back.  The added advantage is that the back plate allows for some lateral adjustment in case the carcase is slightly out of square. 

I have found the Blum PDF's on cabinetparts.com ( may be on Blum's site also)  to be most helpful.

Dan,
I use Tandems on most kitchens I do, but have never used the back mount metal brackets. I mostly use them on Euro boxes with inset 1/4" backs using the system holes in cabinet to attach runners. Will the brackets work with 1/4" backs, for when I do face frame ? I usually block out runner for face frame which is time consuming.

Just as a note of interest the original poster is in South Africa and the Tandem products you are discussing appear to be specifically for the US market. He may only have the European version available to him which don't have a back mounting ability and are actually quite different. In Canada, to my Knowledge, we only have the European version available from commercial suppliers. Personally I wish we had access to the US version of the Blum products from commercial suppliers. I would also like to try the Blum Solo undermount slides which seem to be US only.

I deal with a brand of cabinets that uses 1/4" back.They put a 1/2" wood strip where those brackets are.I never had any problem.I use that same manufactuer when i did my kitchen.Full extension/blumotion BLUM runners.  No problems !

Guys

Thanks for all the advice.  Blum sells through an agent in South Africa and we only get a limited number of Blum products through them, but I will check if they sell the back plate.  Our version of the slides do not have any elongated holes.  Has anyone drilled out some of these holes toe make them elongated?  I am worried about rust as we live quite close to the coast, but maybe these slides are made of a blens of metals that will not rust.
