- Today we're using a line bender to form some acrylic for our new CNC dust shroud. We're not that good at it - come watch!

If you speed the video up to 1.75x he speaks at a normal pase and you'll save some valuable time whilst still learning whatever your here to learn.
Point taken 🤣
Sorry mate, no offence.
No offense taken! Sometimes we suck at talking while our attention is focused on the crap we're doing🤣
I really appreciate your idea!!! I’m going to pin your comment so it comes out first I hope you keep the good ideas flowing!
Ah no worries, thanks mate.
I look forward to learning some more from your videos, cheers.
Nice work! I've never seen that done before.
We do it badly! 😝
Line bender tape? I have never seen that before. Can you control the temperature? Back when I started in the sign/display industry we modified metal bending brakes with heating elements and made jigs since we were making large quantities. Slightly off topic but when you CNC acrylic with a V Bit do you lubricate the bit during routing?
You could probably control temp with a rheostat, but we don't. We learned about the linear tapes from the acrylic guys we use for complex stuff. No lubricant- did you?
I was going to order a V bit to play with but the instructions said to lubricate for cooling. We typically just use upcut bits for metal.
I wouldn't worry about lubrication for acrylic, for fine etching we use 60 degree V bits or V shaped engraving bits without difficulty :-)
Yeah, I was going to ask the same thing. Never heard of it...sounds a lot better than a torch under plate steel 😂
I was told that the bubbles that form are due to the presence of water in the acrylic and that you need to heat it for a while to dry it out before bending it. Any water in the plastic allows for low-pressure voids to form during the bend (not vacuums).
I've heard something similar! Pre-heating sounds like a good idea😎
Ok. This is new on my quest to build a dust extraction on /for my dremel tool plunge attachment. There are no dust extractors available. Yours is the #2 video I watched so far. Semper Fi.
Fantastic! Matt is the jarhead. He's gonna message you separately!
What is temperature of your heat strip? Can I use a small propane torch to heat bend?
About 250 degrees Fahrenheit or 160 Celsius. I don't think a torch would work for acrylic sheet. I don't think you could get the line to that temperature evenly- you'd risk burning the acrylic or you'd have spots that would be ready to bend next to hard acrylic. 🤓
You may want to try a can of compressed air to cool off the acrylic, as you would hot glue.
Was about to suggest this exact same thing. Glad I read the comments first.
That’s a great idea- why didn’t I think of that?!
@@GratuitousSets Wouldn't the thermal shock be too great? It could crack or am I wrong?
I guess the cold air would cool at about the same rate as the water, but we might not want to spray with the can upside down or have liquid come out of the can... I dunno. I'll give it a shot on a test piece first...
unogazzy84 Test it. It works on hot glue. Besides, it looks more sophisticated than the water. 🧐
i'm not sure if you ever mentioned it, but how thick is the acrylic sheet you are bending?
That was 1/4"! I hope it was helpful 😁
anyone got a good acrylic bending video? I went through about 3 of these how to videos and they are all "learn along" videos.
The plastic makers wouldn't push towards PETG and away from acrylic because that would mean less breakage and fewer sales.
Where is the heat?
We are using a “line bender” there is a heating element in that strip of plywood. You can buy them from plastic suppliers
Wheres the heat?
lol
What happened during the 11 minutes? He didn't say. How can it bend so easily then?
We used the strip heated on it to soften it😎
So there is a heat supply under what he called the line bender? How hot is it?
i'm not sure- They are sold specifically for bending acrylic and don't have a thermostat. It does get a bit hotter if you use it for more than 30 minutes at a time, though.
Nice smooth - on bucket.. Advertising for them, with out sponsorship?? 😉
lol... I know, I know...
Just finished a build using a decent amount of acrylic and now just the word acrylic brings to mind the horrendous smell of cutting acrylic...😵
Yeah- it's awful, and pretty toxic...
need big space to articulate bending. not very friendly user way of bending.
skipped through vid several times and still don't get how the bends are made? heat? cutting? someone please point me to where he explains the bending process.
It's heat- We use a "line heater (bender)" . We place it under the line that we want to bend and wait for the acrylic to become pliable, then bend it at the appropriate angle. Let me know if you'd like for me to get you links if you need to buy one. -Mark
way to put your self down bro
Lol- yep! 😂
Being that this is for “dummies” wouldn’t it be necessary to not assume we dummies know what is a line bender? 🤷🏼♂️
You've got a good point there! I'm guessing you were able to figure it out. It's a heating element that heats a line where the bend will take place. If you call Tap Plastics (the company) and ask for one, they'll know what you're talking about.
For dummies from dummies? Great thanks TH-cam, I really wanted to see someone do it worse than me to give me advice so I can go backwards
Fair point 😂
First
Nicely done!
