Hey guys, heres the 3 video guides by The Mod Zoo for clear hard lining... Mod Zoo was first to discover and use PETG tubing..

Hi all - thought I would also weigh in on the hard vs soft tubing. Just finished updating my rig (posted in the build log section under Red Rampage - new build log to come soon) and one of my upgrades included switching to Primochill hard tubing.

So, some general comments:
1) I did switch over to hard as part of an experiment, but also because of some of the builds I saw, the hard tubing can look amazing (over non-rigid tubing)
2) I went with the 1/2 Primochill clear acrylic with the silver diamond/knurled fittings - all from FrozenCPU.
3) I bought a pretty cheap heat gun ($45) and tiny hacksaw from Home Depot, as well as a little sanding block
4) Also bought the Primochill bending kit, which is basically a couple of heat resistant gloves, silicon tube, and some (tube cleaner?) - for $17 it was worth it.
5) And - for the best part - went to the lego store and bought a bunch of spare pieces and a base that I used for measuring and making my bends - this actually worked out really well (and will post a couple of pictures here)

As far as the bending goes - it does take awhile to get use to how to do it. As for some of the posters above, if you get to hot you get bubbles - need to be patient as heck with it as it is very fiddly. And (obviously) not flexible at all so if your bend is off by more then 1-2mm then it isn't going to flex enough to fit in. I also noticed that you have to be very careful putting bends close to where the fittings are going on - anywhere where the tube gets heated the tube does tend to cool with some distortion making it difficult sometimes to get the top piece of the fitting on. I would also recommend buying more then you think you need - I started with 8', and ran out (also 4' of that probably turned into scrap / had to re-work runs). I put another order in with Frozen 2 weeks ago (as they were out of clear tubing for a week) and I bought another 20' just so I would have future stock.

Another thing I had to do (which is mentioned someone in their videos) is use (in my case) olive oil with the silicon tube, otherwise it would get stuck and I had a hell of a time trying to get it out. Once you embrace the oil, it works better although you need to do some rigorous cleaning afterwards.

I probably spent about 10 hours total making the tubes, bending, cleaning, re-bending, scrapping, etc. Also note that if you have a leak (like I did) its really tough to strip out hardware with rigid tubing - be warned - TEST YOUR w/c GEAR FIRST (like everyone says to).

I am happy with the final result, although like Lofat (I think it was him who mentioned it) it is very difficult to get those uber clean angles - and if you are OCD like me that will bug you a little. But the lego molds really did help - let me try and post one so you can see what I was doing.

Okay, here are a couple of examples of how I used the lego to make the guides for bending the tubes.

so i went to home depot, picked up a temp control 1650 hands free heat gun for 50 bucks, thankfully they where on sale... there was some issues with the transaction... but in the end it was a good deal. got a plastic saw and some painters tape aswell as a brand new set of the primochill revolver compression fittings. the bad thing is that my order from Mc-Master-Carr got cancelled... so i heard back from both mnpctech and mcmaster, looks like im getting my petg tubes after all.

good news.

This is an awesome idea. I've been wasting a ton of tubing getting used to using the tubing and I have a ton of Lego's just sitting around in a closet.

Kudos for the idea.

Maybe I can finally finish up my "Muzzle Flash II" build.

Great vid on the n00b tube bending with PETG. Someone asked about Polycarbonate or Lexan tubing on the comments section.

Just to comment on that, in my experience of bending lexan versus acrylic, Lexan needs a lot more heat and time to get up to temperature, and the interval between flexibility and bubbling up is a lot shorter. Also Lexan is very prone to scratching, even worse than acrylic.

From your video here, it seems like PETG is a great in-between. You sacrifice a bit of durability versus Lexan but benefit from shorter heating time than acrylic, all wins in my mind.

Always great vids though!

I much prefer The Rimmer:
I'm looking into getting one of these. A nice and quick/easy tool to do that job.

I thought it was called the reamer?

I might check here and let you know Acrylic : Online Plastics, Plastic Sheets, Plexiglass, Epoxy, Fiberglass, Carbon Fiber - Plastic World

I've bought sheets of acrylic from them three different occasions and they've been pretty good so far. Their acrylic rods/tubes are in imperial so they will likely only work with Monsoon or Primochill fittings. I just have to make sure the O/D is correct. They have also responded to my e-mails fairly quickly too.

Both are great fittings but the Primochills are a bit chubby IMHO.
