LR32 use

[HowardH]

I just picked up a LR 32 over the weekend and having watched a number of videos from Sedge and others, I'm still not quite sure what's the difference between using the "16" side up and away verses the "32" on the end stops.  It's been made very clear to use the 16 when doing shelf pin holes but I'm not sure when to use the 32 side. What's up with that?

When you use the 16 up and out, the stop block can be used as a temporary spacer so that two LR 32 rails can be joined end-to-end while maintaining correct spacing to continue the 32mm system spanning both rails without error.  This setting can also be used to set the top hole 16mm down from the top of the casework (or up 16mm from the bottom of the casework).  When you put 32 up and out, you can set the system to put the first hole 32mm down from the top (or 32mm up from the bottom).  You'll note, too that there's a 9.5 setting for those cases when you use Confirmat screws to join sides of a cabinet to the top or bottom of the cabinet.  In this case, think of how Ikea joins tops and bottoms to sides as an example.  So why 9.5?  Tops and bottoms are 19mm thick.  Let's say you're making a bookcase.  Whether you use the 16 up and out or 32 up and out, the sides will be a multiple of 32mm.  When you use 9.5 up and out, the sides will be a multiple of 32mm, PLUS 19mm to accommodate the top and bottom in the Ikea paradigm.  Does this make sense?  [smile]

The most basic answer is that 16 up and out will set the center of the first hole 16mm from the top or bottom and 32 up and out will set the hole 32mm from the top or bottom.

You then need to figure out where you need the holes based on the thickness of your tops and bottoms for the cabinets, and the drawer slides you are using. Blum 563 series slides have the hole 37mm up from the cabinet side. If you use 16 up and out, your first hole will be a 16 or 48 mm. Since you have a 19mm bottom on the cabinet, 16 is out which leaves 48 as your first hole. Subtract 19mm from 48 and you only have 29mm but need 37. 32 up and out has your first hole at 32mm or 64mm Since 48 isn't enough, 32 isn't either so your first hole would be best placed at 64mm.

I have other slides where the hole is 16mm from the bottom and some where it is 25mm from the bottom. There really isn't a single answer.

For doors, the cup hinges on the doors are centered between 32mm holes so if you start with 16 up and out for the cabinet sides, you need to drill the cup hinges with 32 up and out on the doors and vice versa.

I use the KISS II system which has the first hole staring at 35mm so I had custom bars machined to facilitate that.

I'm building a base cabinet for my new Tormek 8 and installing 4 drawers using the Blum undercount slides.  I'm going to use the LR32 to make the 32mm holes with the euro screws so the installation of the slides goes easier.

For most Blum undermount slides, there are holes at 25 and 37 mm. Verify this for your particular slides before you take my advice.

If you use the 16 up and out setting, your first hole will be at 48mm. With a a 19mm floor on the cabinet, that will leave you with 29 mm and you can easily use the lower row of holes on the slides and it will leave a 4mm gap beneath the bottom drawer slide.

If you use 32 up and out, your first hole will be at 64mm, minus a 19mm floor leaves you with 45mm. If you use the upper row of holes at 37mm this leaves you with an 8mm gap from the bottom of the slide to the floor of the cabinet.

In this case, either will work with a 19mm floor.

Yes, that's what I'm planning on using with the 16 up and out.  However, since this going to be on the floor, my plan is to build the box with bottom/top being full width and the sides attached on the inside so the weight is being transmitted directly to the bottom of the cabinet, the opposite of what one would do on an upper cab where you don't want the weight to eventually push out the bottom. What I'll think I'll do is cut my balanced panels and mark some test spots to see where the hinges would mount best.

You can also just use a spacer between the stop and bottom of the panel to get your correct offset of 46.5mm center for the 5mm hole from the bottom of the panel for the Blum slides.

Easy to do, you can rip a spacer and pin it to the panel and move to the next. 

If you haven't reviewed the Blum Process 32 document, you may want to take a few minutes to do so.
