How to fit knobs so they turn??

(33 Posts)

Apologies if this is the wrong section!

I'm making a toy kitchen for my DS and have come up against a problem with the cooker 'knobs' - I think I need double-ended screws to attach them to the table I'm using (an ikea lack) as the top is one solid block, however I really want them to be able to turn as that seems to be where DS has most of his fun!

Has anyone any ideas how I go about this? I don't want him to be able to unscrew them obviously!

I don't know.

But, what size are the knobs and what are you fastening them to?

double ended screws will be fairly expensive and will come undone.

Nope they're more like this - I pinched them off a chest of drawers someone was throwing out!

I have ordered these and will be fixing the knobs to one of these

Use the screws you've been given squirt a load of strong glue over the screws before screwing the knob on. The screw the knob on until it is close to the "cooker" but the screw still turns in the hole - you will need to drill the hole slightly larger than the screw.

The knob will then be attached to the screw but the screw will turn in the hole through the cooker.

(how many times can I use the word screw in a post?)

SoupDragon Sat 29-Sep-12 13:25:26

The hole through the table only needs to be slightly bigger than the screw as you don't want droopy knobs [gratuitous innuendo]

glue the screw into the knob and put washers on the outside and inside of the bit the screw goes through.

so...glue into screwhole in back of knob, washer or two onto screw put screw through the drilled hole, add another washer or two and fix knob to screw.

soupdragon if the holes are bigger than the screw what's to stop the knobs being pulled off? <snigger>

catsmumma there isn't an accessible 'inside' - its a solid block, you can't get to the back if that makes sense?

SoupDragon Sat 29-Sep-12 14:35:55

Er... the head of the screw!

SoupDragon Sat 29-Sep-12 14:36:34

If it's a solid block you're stuffed.

SoupDragon Sat 29-Sep-12 14:38:49

OK - brain in gear.

You attach the knobs as described but to a separate piece of wood.
On the table, drill shallow holes to accommodate the head of the screw or countersink the back of the separate wood.
Attach the separate wood to the table edge.

There isn't a head of the screw, they're pointy at both ends to allow for the solid block problem!

SoupDragon Sat 29-Sep-12 14:42:48

IMO it won't work with double headed screws. You need ordinary ones.

I had considered a separate piece of wood but am too lazy in heavily pregnant/in pain state to go to the shops thought it might be possible without.

Darn it. Back to the drawing board it is then. If it were for any other child I wouldn't bother with them turning but it might keep DS's mitts off my actual oven--for a bit-- if I do manage it. Thank you for all the suggestions

Strike out fail

The problem with a double headed screw is that it will be fixed at both ends, thus not turning. Well, they do turn but they unscrew. The knobs on my TV cabinet twiddle off nicely leaving a pointy screw. [sigh]

Yes that's my concern. So I think I either need to forget the turning idea and glue the screws into the table and the knobs, or get a separate piece of wood, screw the knobs into that so they turn and then screw that to the table. Due in less than 3 weeks and want the kitchen to be a present 'from the baby' - I think I'm being a little ambitious but determination will get me through (plus I want the satisfaction of doing it myself/saving a fortune on a bought one)

PigletJohn Sat 29-Sep-12 16:11:15

those knobs you were given - do they fix with a woodscrew, or have they got a threaded insert for a bolt (machine screw) to fit? If so, have you got those screws?

They fit with a wood screw

tricot39 Sat 29-Sep-12 23:14:55

I might be missing something but i think i would get some long wood screws, washers - maybe as close to the knob diameter as possible. The screw shank should pass through but not the head.

Drill a hole in the table bigger than the screw diameter so that the teeth slip through but no so big that it is loose.

put 1 or 2 washers on the screw and push it up through the hole in the table. Put another 1 or 2 washers on. Drill a pilot hole for the screw in the knob. Fill with glue. Screw the knob on to the screw so that the system will turn loosely in the hole.

Does that sound like it might work?
I have got slightly distracted by the inneundo possibilities of this thread so may not be making sense <titter>

tricot39 Sat 29-Sep-12 23:16:39

Btw i think this is a brilliant idea. Please post pics when you have done it!!

SoupDragon Sun 30-Sep-12 08:09:55

Tricot - apparently the table is solid so there's nowhere to screw. [snigger]

Right I've bought a separate piece of wood to screw on, will be trying out some of your ideas tonight and tomorrow (bump permitting) - will try and post some pics if I can work out how!

Do not glue or screw anything to your bump!

PigletJohn Mon 01-Oct-12 12:21:16

easy now

drill a hole through your new batten which allows the shank of the screw (but not the head) to pass easily through without binding. Countersink it so the head will nor bind when fixed to the table

Pass longish screws through the holes in the batten and screw them into pilot holes in the knobs. If you have any washers, put a couple between ther knobs and the battens.

Tighten them until the knobs will no longer rotate, then slacken off a fraction

You can now screw the batten to your table front

(You might like to paint rings and numbers on the batten around the knobs, and arrows on the knobs - it will be easier to do that before fixing)

I've ordered some numbered stickers for the dials. I don't plan on attaching anything to my bump, I don't think they'd allow a toy kitchen into the birthing centre ;I've already packed way too much!

Thank you, will be trying that later! Not too sure about countersinking but will do my best!

PigletJohn Mon 01-Oct-12 13:07:30

if you have a set of drills, you probably have one with a conical head like a stumpy christmas tree. That's a countersink bit. You put the point of that into the hole, and it will rasp out a recess that the head of the screw will set into.

Otherwise, you can use a larger drill the size of the screw-head, but don't go in deep - just half a second on the trigger will do.

Thought you might all like to see the end result - pictures are on my profile!

In the end I screwed the knobs to a separate piece of wood with a nut behind the wood and a washer in front, I then screwed the piece of wood onto the side of the table making sure there was enough space behind for the nut to stay still against the wood whilst the screw could turn.

Thank you for all your help and interest!

[applause]

Well done - it looks great smile

PigletJohn Wed 03-Oct-12 19:38:26

it looks very nice

how about a grill-pan under? smile

I'm sure I'll have lots of ideas for additions at a later date (plates etc, possibly an oven) but 1) I don't want to overwhelm DS with too much new stuff all at once especially when it's not Christmas and 2) I'm 38 weeks pregnant and knackered! I will see how he gets on with it as is, I'm sure in a few months time I'll be planning another project!
