as an ex-fabricator, I think you have done a rather good job explaining in such a short time a nice basic instructional so well done, one thing to note is that as acrylic sheets are formed like a dough that you cant guarantee that your polished face your gluing to is 100% flat either. And on a safety note, liquid acrylic welding glues work by liquefying the materials therefore actually welding by mixing two liquid components and the bond is formed as the solvent evaporates . And just realize that alot of acrylic glues are derivatives of chloroform, just industrialized for safe handling. so make sure that your in a ventilated area as it can cause problems.

This is one of the most beneficial videos I've seen regarding this process. Thank you.

Don't use a sponge sanding block. It rounds rather than flattens a butt joint surface. Use a solid block and keep it flat against the edge.

Having worked with various types of acrylics and poly's, I find its easier to fire the end of the plasic untill it becomes transparant and lighty pressing it against a straigt edge piece of metal to cool; perfect angle every time.

This video was extremely helpful thank you!

Wow- you are really helpful!!! I am going to do whatever I can to support you.

Very helpful tutorial! Thank you for this!

The drawing in of the fluid is called capillary action. The surface tension between the close surface is lessened for the fluid than forming a droplet in the air

Hello! great video, recently i have been thinking of making a replica Gibson L5 archtop guitar and i wanted to try making it out of arcylic! hopefully after testing and extensive design and testing. i live just outside of Toronto but still in the gta. i will definitely have a look into plastic world, they have every thing i think i will need! thanks for making this video!

very good info , thanks for the vid.

Thank you great information

Yes, a lot of talking, great, a lot of info too. Good video. Thanks.

I was wondering if you can use water first to check for gaps?

It's better to wet sand any plastic if you can or wear a respirator as fine dust is very dangerous. Keep the area clean after with a hepa vac and make sure you air out your work area. Thanks for remembering us ladies and how we like to do this stuff too.

Good info Blish K

thanks a lot for this :)

well done !

It's solvent, not glue. It softens and merges the material at the molecular level. That's why the process is often referred to as solvent welding. Glue is just that - glue. It sticks to each surface and forms a bond. Solvent evaporates and leaves behind the joined surfaces.

what thickness sheet would you use for a sump about the size of a 40 gallon breeder ? always great videos thanks.

cool, thanks so much...

Thank you.....

hey man, im from mexico i got my own bussiness, im starting :) i tried to glue a box 2 meters large x 1.30 w, i used a syringe to glue my weldon , the problem is that some glue droped in the acrylic .... and i need to clean that because the client wont accept the work like that .... whats the best method to do it ? im going to use NOVUS 1 and try to polish it off , its there another way to do it?

if your in the situation where your sanding the acrylic do you have to worry about over sanding trying to get that smooth edge?

is this strong enough to withstand the pressure output from 4 subwoofers? Or should I use screws too?

As we say in the NAVY you can tell how much a person knows about something by length of time they can talk about it. Quite knowledgeable however, there is a glue that is kind of syrupy about like model glue available that can help when your edges aren't so smooth 😉

@@krishs9467 Hi, I don't do a lot of this k8nd of work but the I used to make our fish aquarium I can't find. It is quite similar to SCIGRIP 16. I haven't used this one but there are others out there as well. It has been a long time ago but I think the one I used may have been made by Dupont. Just search for acrylic glue by Dupont

I learned an awful lot from your video. It was extremely helpful 2 me as I was looking 4 an alternative 2 CA glue 4 a craft project using colorful pieces of acrylic. Maybe I'm just glue challenged, but I found it a messy pain 2 use. I experimented with acetone and it did work, but I want 2 try the weldon 4. I have a new Freud blade on my miter saw and it seems 2 cut quite nicely. When u use a router, what sort of bit r u using?

There is no Weldon 1 or 2. There was briefly a Weldon 5 years ago, but it no longer exists. Weldon 3 is intended for extruded acrylics and Weldon 4 is good for continuous cast and cast acrylics. 4 can be used instead of 3 on extruded acrylic with slightly longer setup times, but it's best not use 3 on cast acrylic. All of these joints will degrade fairly quickly, so if you intend to make a decent sized aquarium, intend to make one every other year or so as the joints WILL fail.

if you are unable to get the weld on is there any jb wel;d or something like it equivalent?

Very ambitious... for the sanding you can tape a bit of sand paper on the table and sand the edge moving the whole part. If its small like the one youre demonstrating with. And could it be that the glue you are using is Aceton?

i wanna see how you cut and use the router too..

How to disjoint the acrylic sheet which were glued or how to remove the glue?

How strong is the bond on a 90 degree and 180 degree butt end joints? Does 1/2 inch weld better than any other size like 3/8?

Dissolve and evaporate to bond. Acetone should work.

hello i used chloroform for bonding 12 mm acrylic sheet ... bond are superb but now i want to dis-mental bonding .. how can i do ... with help of any chemical or tech ????

I can second the tip about the router. I cut my panels in wooden jigs with a router and it leaves by far the cleanest edges you can get from a cutting tool. They never need sanding and if you need rounded edges you can skip right to buffing.

To those of you who have cemented acrylic successfully: On the four brand new sheets I will be using, each one has a sort of "lip" on the longest edge. While all sides are perfectly square/straight/gapless, do I need to prepare that one side by softly sanding it down. I can provide pictures incase I'm not making too much sense. Thanks!

Are there different types of acrylic out there?

Can you test for gaps before bonding by using a needle bottle of water instead of glue? This way you can see if the water solution fills all of the bottom of the acrylic piece. If there are gaps, then resand and test again. I havent tried this testing phase personally. Would this work?

+ScreamHouseGames I suspect this would be a relatively safe way of testing for gaps; keep in mind, though, that water may tend to fill the gaps more readily due to surface tension.

HI, I am in the waterloo Kitchener area, how can I buy the glue from near by or online?

bro...acetone, u can thicken it up a little by dissolving chunks of scrap acrylic in it. if you spring for the glue ive noticed number 4 can handle shittier rougher cuts with a better bond. but considering how much acetone you can get for a few bucks it might not be worth it. cool tip with the pree squeeze on bottle. you do talk a bit more than needed b4 but there is some great info in here. I've also found that my miter saw plus a 26 buck 80 tooth blade from harbor freight produces chip free cuts that bond well with little to no sanding.

Hello, question if anybody can help me. I got a 600-gallon acrylic aquarium for next to nothing on Craiglist, the acrylic is 1.1/2 and it weights around 1000 lb. The front and top panel are off so I had to cut it in order to assemble it back together. I only cut one side thought. My question is how do you prepare the edge of a sheet of acrylic that weight almost 300 lb?. I'm having difficulties with the router since it does not go all the way through. And moving it around its a nightmare, It can be done but short distances between 3 or 4 people for the front panel alone. I need help in preparing the edges for 1.1/2 inch acrylic. I've been doing it with sandpaper, please let me know.

Don't depend on 'eyeballing' to determine the quality of your joining surface prep. Learn to make straight cuts, prep with a router where possible, and use feeler gages to check for gaps.

Yes, as i understand the acrylic welding method is really quite similar to metal welding, as the chemical kind of softens or loosens the molecules on each piece, so they really bond together, almost as they where one piece!
