Just thought i'd share. Something i have volunteer in making for my boss. material cost and labor covered of course

something like this

but not excatly

it will be built out of mdf and acrylic. Hence i will be mdf shopping later. Finally i can buy mdf for myself , for new jigs!

FIrst time i am working with mdf

I held by breath hoping that the load would fit in the basement since i dont want to carry the 39 kilo sheets on my own.

I now see how laminated mdfs are very attractive to cabinet makers. Lessens the turn over rate by more than a half since no need for finishing! damn thing swells like a sponge though

predrilling had to be almost as deep as the screw, unlike wood or ply where we could get away with less otherwise you get nasty cracks

So far this is the purpose of my right angle clamp. A form of counter weight hehehe

Here comes the test of High School Physics... I need to make independent switches for the T5's and the Germicidal UV plus have both of em in one plug. Come to think of it i have been fiddling with household electrical stuff rather early on before i did woodworking

Nice house and clogs! Haha!

Kidding aside, nice work on that sir Ben, I do pray that you beat your Monday deadline for this. Question on one of the images above, did you clamp the two sheets because you'd glued them? Would the glue hold the laminate with the cut end of the MDF?

they were clamped so i could drill and drive the screws. I have yet to make a cabinet inside right angle clamp for this purpose

Hi Rolly

I got the laminates at World Class laminates

1,480 for two sides white matte laminate

The one in wilcon is more expensive ( i just found out why) coz the laminate on the world class is thinner and the ones wilcon sell have a fairly think laminate its at least twice thicker. i think its 1,900 at wilcon, if using as counter top id get the wilcon laminate.

I will definitely keep that in mind for future commisioned works (hopefully more to come)

The monday deadline isnt a YOU ARE DEAD!! if its not there. Its a deadline i set because i am busy as hell these days.

On monday i will have the Hepa filter supplier get back to me with sizes so i can decide what to do with the back :)

they were clamped so i could drill and drive the screws. I have yet to make a cabinet inside right angle clamp for this purposeOh, now I get it. So this is all a drill and drive assembly for the most part. By the way, I saw a generous roll in one of the pics, how do you plan to attach the edge bands or watchamacallit?

hahahah nope its not (thank goodness) its a whole screw. It has a pair right about ten inches at 6 o'clock

its for the t5 brackets. I have to make a drill/screw alignment jig for 3/4 thick material soon. I drill by sight.. so far so good... but the screw heads dont align to each other :P

Hi Jarod

Edge banding.... i am scratching my head coz i hate handling rugby.... i had an option of having the supplier apply a heat activated adhesive on it.... damn.... i didnt opt for that mainly coz i wanted the experience of using rugby ( i am sure there is a much better adhesive than rugby for this. )

timber715
05-17-2010, 01:27 AM
the better choice Ben is the heat activated adhesive, only drawback is you need a flat iron to apply them.... otherwise it is just rugby....

jarod
05-17-2010, 01:51 AM
Why do you hate rugby? I had a handful of experience handling rugby before since we use that in adhering formica to wood in our small family business. The way I see it, the more you use it, the more you'll appreciate its strength and cost. Most people find it messy but once you get your flow and technique, it's a breeze. Only drawback is the curing time and the very fast setting time once you meet the two "rugbied" sides.

I assume you know but most people put rugby on one side then stick the other side without letting the rugby dry a little bit first. Just put enough amounts to cover both sides, let it dry for about 15 mins then carefully stick the two sides and follow up with massive amounts of elbow grease. For the case of edge banding, it would stick as hell!

Or you may also check the "No more nails" product which I see the little sample products displayed in hardware a little convincing.

http://www.bostik.com.ph/home.aspx

Btw, are you just asking how to stick your project hours before your deadline? Haha, just kidding! If you only have rugby, you may try it first and decide if it's your thing. Just don't inhale it froma plastic. Bwahaha!!!

beebeenator
05-17-2010, 08:32 AM
I tried rugby before trying to re attach the sole of my shoe... messy ehehhe. Well i moved the deadline hahahah

sounds simple enough. How do you handle the run-off or squeezed out rugby? does thinner work?

I don't like ruby either however it is has its applications: waterproof, flexible and quite strong when applied properly.

Yes, very nice job there Bee. Nice house too. Is this some kind of workbench for working with chemicals?

beebeenator
05-17-2010, 10:06 AM
yes it is Louis, its for biological samples actually. Need it for a laboratory in the slaughterhouse.

The thing that makes it work is simply the HEPA filter (which is not attached nor acquired yet, so much for deadlines hahaha)

Then a germicidal UV light (really nasty stuff) for non-detergent/liquid based disinfection

jarod
05-17-2010, 11:16 AM
^^Rugby is best removed when partly dry such as wood glue. You may use a scraper to remove the part from where it just exits the sandwhiched sides and just peel the entire thing out.

This is also one thing I like about it, the stuff doesn't dry that fast so you have enough time to correct your mistakes and it's nice to you until you meet both sides where all friendships end becomes a one-shot deal.

As lncc63 put it, it is a good adhesive when applied properly.

beebeenator
05-17-2010, 04:01 PM
hmmmmm i will buy rugby

I took a sick leave today at work. Was really sick but went back on working this.

Note to self, acrylic shreds that pop out of the table saw is PAINFULL!!

took 30 minutes to decide if i will have a swinging acrylic opening or sliding.

I suddenly had accidental runners after trimming some of the sheets. Hence i used it :) so sliding it is

The runners are mighty bonded onto the laminate... dang thing sticks straight away. It has been years since i p[layed with superglue.. had my fingers bonded!!! onto an acrylic piece!!!.... sakit......

deadly germicidal uv lamp. I could sterilize my son's milk bottles in here HAHAH

edgebanded.. painstakingly.

This project pretty much taught me how to handle acrylic (less the heat bending but lots of cracking!) and mdf

now all it needs is the HEPA filter.........

Bee you painted the switches? Eiw! Except for that, nice work, I agree.

Didn't you get dizzy from the reflected UV? I once made an EPROM eraser (electronics thing) which has UV lamp. I got dizzy when I took a peek to see if it was working. Same thing happened when I build a water disinfection unit for our aquariums.

Hi lncc,

NOpe i didnt paint the switch.. it really is white.. The whole thing is asylum white hahaha for hygiene purposes

You are into aquariums? i am into planted tanks, planning to make a monster 6 - 7 footer tankbcabinet and stand.

Thanks JayL :)

Timber, hmmmm yeah i should huh.. .on top of my "amateur" fee for making it :)

Apologies are due then. I just get really ruffled when I see fixtures with paint on them.

No, we're not into aquariums anymore but at its peak we had about 400 gallons of display and 2000 gallons of filtration (marine aquariums). The stands and hoods were actually the last pieces of "furniture" I made before I decided I wanted to go fishing instead. Used to fish a lot but from shore, this time I figured I'd build me a boat so I did. Engine prices were absurd then (still are actually) so I decided to fish from a sailboat but then I discovered that that sailing is very enjoyable too. I already have the plans for my fishing boat and the engine as well so maybe it will be the next long project. It usually takes me 2 years to finish a boat (daming side trips kasi).

@beebeenator:

Nice final product, you could now start your own business of lab laminar flow equipments, custom made pa! I like the design, it inspired me to create a miniature for my arachnids.

@lncc63:

It's nice to hear someone that wasn't satisfied with marine aquaria decided to build a boat and get into the real thing! Akala ko pang movies lang yun, I salute you sir!

that piece of acrylic gets glued on to the hepa filter/blower. It in turn gets glued on the plexi backing. Hence the need to trim the white plastic shroud

i need to seal all the holes where the wires went through also.. I can probably do that at the farm.

all meeting corners will also be sealed.

The plexi backing was made to facilitate easy changing of the hepa filter (which honeywell told me they are out of stock.... ) hrmmmmm

very nice work Bee, another tip for jigsawing plexi is lower the speed, nonetheless it is excellent work...
as for the plexi closing after cutting, I have gone there once and it is indeed a learning experience, sharing them will make others glide thru without the passing that stage. but it is a fun thing to find out for yourself...

beebeenator
05-19-2010, 02:46 PM
Thanks Timber! :)

one thing i experienced in this build is the use of so many tools. It is one of those rare moments where i DIDN'T have to substitute one tool for the work of another that i dont have.

There is just this wholesome sense of satisfaction where i have all tools that i needed.

ftom the TS, CMS, JS. rotary tool, CD (cordless drill hehe) , And the assortment of proper blades and bits for the job.

it would be great if i (or US in our community's case) can work from home and spend more time with my family. But that will still be at least a few years away. Something like what Benjie Reyes does.

no need Ben, the block planes works well enough for me, you can check with your MDF supplier though since they have the heat treated edge-bands. Panda doesn't have a full catalog and they dont have this as well as far as I know.
