Kitchen cabinets - like no one makes em

[philxyz]

Hello, beginner here, planning my first kitchen build.

Why does no one build cabinets using a wood frame structure skinned with a thin(nish) ply?

I have a drawng which saves me loads of ply. Looks great in CAD. No idea how it might stand up. I could add diagonal(?) support to brace the square in the absence of the back panel.

But I guess there's good reason why everyone uses 18mm ply board boxes. I don't know.

Thanks
Phil

It's a bit hypothetical at this point Phil, but normally one's sense of structure is based on experience. From yr brief description I can't see anything wrong.

But you haven't explained a huge amount.

Maybe the crux is that you have to hang doors / drawers / shelves etc off something, which in yr frame / panel model wld need frame members to be designed in at suitable positions?

Nothing wrong with your approach, it’s the way cabinets used to be made. Where time is money, it’s not the most economic way of making cabinets these days, with modern materials.

Thanks very much for the replies.

"But you haven't explained a huge amount."

TBH I am a little unsure what info is useful and I am only beginning to plan, but here's a go.

-All units will be on ground and pinned to walls
-Fully integrated kitchen appliances

I am thinking 40*70 frame, maybe maple? With 6mm birch ply skin (dare I consider 3mm) and 12mm ply shelves. But is that way too light?

-Would a 40*70 frame on the ground, pinned to wall, be strong enough for fridge freezer and dishwasher?
-How wpuld you joint the framing?
-Would you put some diagonal support to brace the square (not in my image)?

I have never done this but OK with table saw, router etc.

Here are a couple of CAD pics I did today to gove an idea so far. Those top four units are more general storage for a small house.

AFAIK the old postwar kitchens where made like this 1" corners and 1/8"mm plywood glued over the sides, back etc.

3ft for a double unit.

The reason I think people stay away from the method of frames with inserted panels is simply time.
These are more labour intensive than just squares of mdf (decent plywood is quite a bit more expensive than mdf as well).
You need to do joints and router slots etc.with a frame.
With mdf you just whack in a few domino's or screws and it's done.

A kitchen manufacturing line takes 8 minutes to eat mdf at one end and spit out a finished cabinet at the other.
It is mostly not worth building your own carcasses unless you are going very posh.

Thanks Ollie. I get what you're saying but perhaps it makes sense for me. First ever house, approaching retirement. I will have time and no money. I have a router and access to a table saw. This will probably be the only kitchen I ever build so I am happy to take it slow.

And, in blissfull inexperience I reckon I can save on materials. Done in same materials the frame/skin method is cheaper, right? It couldnt get cheaper material wise than frame/skin with pine and mdf could it? Although I must admit I am thinking maple and birch ply.

Back in the 50s'60s/70s Liden Whitewood (in Lea Bridge Road, London E10) made kitchen and other furniture with frames and thin plywood - supplied un-painted. Liden was one of a large number of furniture makers in the E/NE London area - the North Circular at Edmonton was home to Nathan, Wrighton plus others and in Tottenham there was a massive Harris Lebus factory.

Google "Liden furniture" and there's load of stuff on the subject.

I installed a Liden kitchen (i.e. the cabinets) in the first home of my own in about 1970.

If you have the time an inclination then there is nothing wrong with the frame method at all. It will probably be a lovely kitchen.
You can make it exactly to your own design.
Price wise not sure if it will be much different. If using thinner panels I would stick to plywood. Maple and birch ply could be great looking.

Don't forget about the hinges and runners, don't cheap out on them.

My goodness.... that's a 'blast from the past' I remember this style of cabinet. I had some in my bedroom as a 'kid' Those particular ones came unfinished and had to be painted by the customer. They were very light-weight and felt a little 'gutless'

 

[peter-harrison]

They were made that way because of the rationing of materials during and after the second world war. There was a table of materials for every piece of furniture and they were inspected to see that the makers hadn't used too much.
This recreated artificially the mediaeval order where materials were expensive and labour cheap. People used their ingenuity to get good results from not much.
I've taken several pieces apart and it's amazing how little there is in them, I'm pretty sure that 3 or 4mm ply was very much used.
Although it's not an approach that would work for a modern day furniture maker, it could well be absolutely right for you.
I would recommend that you spend a lot of time drawing and planning, and make a prototype, or at least one of the smaller cabinets first. The Utility furniture would have been prototyped and any kinks sorted. It would be a pity if you cut up all your timber and then found you'd made a basic error.
Good luck!

I would say because of the so called euro 32 system where a factory can throw out a mass produced cabinet with little hands on skill. We are in a world of chipboard and foiled mdf but don't let that stop you thinking of more traditional assembly.

With mdf you just whack in a few domino's or screws and it's done.

The modern way, quick and easy but you get an mdf cabinet, I like using a wooden frame with 12mm ply panels, it gives a solid traditional look that you don't get with a shed kitchen. The groves are easily cut on a router table or with a handheld router and jig but they do take more time so you need a batch process where all cuts are done at the same time, it saves the set up time. Another plus is that with butting man made sheet material together you must have perfect clean cuts, with a ply panel in a frame the edges of the panel do not need to be perfect as they sit in the slots. With ply you will at some point need to edge it with real wood and using these cutters sorts that one out,

This is a plan view of a unit I am currently working on, double shaws sink with three cabinets each side using frame and panels with inset doors.

My older kitchen cabinets were more or less stick frame in place in the kitchen and face frame attached - plywood on the bottoms and sides where necessary. Worked great for probably about 45 years.

I made 1/2" ply box cabinets with face frames but all of the shelves and bottoms are dadoed. They're 10 times as strong as the original cabinets (but don't need to be, they just are).

I don't have a great answer for you other than having worked in a cabinet factory during college, the plywood bits come out of a CNC off of an order roll, fully digitized even back then (1990s) with a ticket and ID for every part, and "the clamps" would assemble a cabinet and install a face frame in less than two minute.

Much of what's made here now is 3/4" stock, often particle and not ply, and held with designed fasteners. More or less factory-made RTA where the A is already done.

I bought ply with two A faces so that all parts of it would look good. The cost at the time for cherry was only a little bit more for one A face, and the core is wood with very little glue. It was a treat to work with because the veneer wasn't super thin and the core could be worked with hand or power tools smoothly because it wasn't mostly hard adhesive.

I counted over 80 joints in that structure. Even using pocket screws it will be very labour intensive. You will also have the problem of mounting hinges and drawer runners.
The Yanks like a hybrid system. They screw plywood together to make boxes and put a face frame on the front. It has some merits - you can use a quality hardwood on the front to match doors and drawer fronts. You can also use cheap self closing hinges if you don't mind the appearance. There is probably no way of avoiding soft close runners for drawers as everybody likes them. I built my kitchen out of ash using this method thinking it would last 10 years - it's still there after 30 years.

 

[Spectric]

I tend to use dowels to join frames together, yes can be time consuming but always precise and the joints close nicely without having to heavily clamp. What I like is that you can make it in parts and no rush to assemble, but with dowels you don't want to many to fit and glue in one go. I do have a domino 700 but that now lives in the shed with the lawnmower, my dowel jigs are just so precise and easy to use with 100% accuracy everytime, not most of the time.

There's a little bit of everything here. Assembled box either with glue/staples or screws is common - in smaller shops making cabinets probably all screws.

There's plenty of frameless cabinet offerings, too - especially in commercial spaces.

The builder cabinets at home stores look like they're made a lot the same way we had ply or particle boxes (staple and hot glue) way back in 1996 - not sure what the doors are, but they're generally pretty crude. As in, the rails and stiles are wood, but I'm not sure about the center panels. if they're oak (red oak is super cheap here). Once they look like maple, all bets are off. "plus quality" cabinets that my inlaws got in a new house look very nice, but I think all of it is very well done adhesive veneer or substrate or some other industrial process.

I put in cabinets of solid wood and my wife often remarks that she likes the inlaws cabinets better because they don't "look dirty" (her word for any grain variation is "dirt".."the wood looks dirty")

 

[clogs]

made a lot of kitchns in Africa for new houses...
I actually took a Wadkin panel saw to do it....
face framed and ply....
no backs, straight onto the painted wall....2x1"s Hilti nailed battens.....
very rough job and these were 1/2 million pound houses 28 years ago....
talk about embarrassing.....
same for fitted wardrobes as well.....utter rubbish....
Philxyz....
there was a v nice hand made kitchen in the US featured on here...the educated members will prob know it....

Yes thanks for reminding us, it was really well thought out so will look for a link to it.

If you like the idea of constructing frames with ply sides, then I would not dream of dissuading you. It may be satisfying to do the full job but I would not follow this approach - MDF is quick and cheap to manufacture:

• buyers can easily change the number and position of shelves using simple shelf supports
• durable, - particularly with 18mm thick carcasses which are the norm
• rigid - thin ply is not, possibly OK if supported by a frame and adjacent units
• easier to finish as surface is flat - unless you want the face grain
• easier to clean - fewer joints to collect dirt
• with foil covering requires no finishing bar visible cut ends (eg: tops will be covered by worktop, backs not visible)

There may be little difference in material cost (although I have not done the calculations).

I also suspect that for the cabinets there may be little difference between your material cost vs the cost of buying completed cabinets (buying power of manufacturers). Doors and trim by comparison always seem expensive and this is where the larger savings may be possible on a DIY basis

What are your dowel jigs?
