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.

@GratuitousSets 3 года назад

Point taken 🤣

@3arl362 3 года назад

Sorry mate, no offence.

@GratuitousSets 3 года назад

No offense taken! Sometimes we suck at talking while our attention is focused on the crap we're doing🤣

@GratuitousSets 3 года назад

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!

@3arl362 3 года назад

Ah no worries, thanks mate. I look forward to learning some more from your videos, cheers.

@saddle1940 3 года назад

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).

@GratuitousSets 3 года назад

I've heard something similar! Pre-heating sounds like a good idea😎

@christophersoprano-sculptor 5 лет назад

Nice work! I've never seen that done before.

@GratuitousSets 5 лет назад

We do it badly! 😝

@thomasgibbons353 2 года назад

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.

@GratuitousSets 2 года назад

Fantastic! Matt is the jarhead. He's gonna message you separately!

@KB-yy7zt 5 лет назад

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?

@GratuitousSets 5 лет назад

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?

@KB-yy7zt 5 лет назад

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.

@GratuitousSets 5 лет назад

I wouldn't worry about lubrication for acrylic, for fine etching we use 60 degree V bits or V shaped engraving bits without difficulty :-)

@JW-hh4qg 5 лет назад

Yeah, I was going to ask the same thing. Never heard of it...sounds a lot better than a torch under plate steel 😂

@Jaze2022 Год назад

anyone got a good acrylic bending video? I went through about 3 of these how to videos and they are all "learn along" videos.

@twistedendingsproductions2782 5 лет назад

You may want to try a can of compressed air to cool off the acrylic, as you would hot glue.

@smappdooda 5 лет назад

Was about to suggest this exact same thing. Glad I read the comments first.

@GratuitousSets 5 лет назад

That’s a great idea- why didn’t I think of that?!

@unogazzy84 5 лет назад

@@GratuitousSets Wouldn't the thermal shock be too great? It could crack or am I wrong?

@GratuitousSets 5 лет назад

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...

@twistedendingsproductions2782 5 лет назад

unogazzy84 Test it. It works on hot glue. Besides, it looks more sophisticated than the water. 🧐

@billjones5178 2 года назад

What is temperature of your heat strip? Can I use a small propane torch to heat bend?

@GratuitousSets 2 года назад

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. 🤓

@philg4116 Год назад

The plastic makers wouldn't push towards PETG and away from acrylic because that would mean less breakage and fewer sales.

@jfresh2054 4 года назад

Wheres the heat?

@GratuitousSets 4 года назад

lol

@LoStKaWz1977 11 месяцев назад

i'm not sure if you ever mentioned it, but how thick is the acrylic sheet you are bending?

@GratuitousSets 11 месяцев назад

That was 1/4"! I hope it was helpful 😁

@treefarm3288 3 года назад

What happened during the 11 minutes? He didn't say. How can it bend so easily then?

@GratuitousSets 3 года назад

We used the strip heated on it to soften it😎

@treefarm3288 3 года назад

So there is a heat supply under what he called the line bender? How hot is it?

@GratuitousSets 3 года назад

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.

@swishpan 6 месяцев назад

Where is the heat?

@GratuitousSets 6 месяцев назад

We are using a “line bender” there is a heating element in that strip of plywood. You can buy them from plastic suppliers

@JW-hh4qg 5 лет назад

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...😵

@GratuitousSets 5 лет назад

Yeah- it's awful, and pretty toxic...

@AR-mb3id 2 года назад

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.

@GratuitousSets 2 года назад

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

@VJGREEK 5 лет назад

Nice smooth - on bucket.. Advertising for them, with out sponsorship?? 😉

@GratuitousSets 5 лет назад

lol... I know, I know...

@thesultanmerchant 2 года назад

need big space to articulate bending. not very friendly user way of bending.

@tommywilliams8953 5 месяцев назад

For dummies from dummies? Great thanks RU-vid, I really wanted to see someone do it worse than me to give me advice so I can go backwards

@GratuitousSets 4 месяца назад

Fair point 😂

@unboxinggiveawaylt1615 5 лет назад

First

@GratuitousSets 5 лет назад

Nicely done!

@alanmatthews9260 Год назад

Being that this is for “dummies” wouldn’t it be necessary to not assume we dummies know what is a line bender? 🤷🏼‍♂️

@GratuitousSets Год назад

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.
