My Toolbox just got Bigger!

Was getting fed up trying to cut plastic tubing, and metal tubing and not getting the cut straight so I bought this which arrived today

No idea what I will do with the PTFE tape 

Gondor

I've got one of the mini pipe cutters (the smaller one with the knob).  It's very usefull when I remember to use it. Just take your time when cutting styrene and don't screw the knob in too fast (a good tip in a number of other situations).

Use it to patch the non-stick coating on your pans when it wears out...

IIRC PTFE tape is toxic.  Particularly for smokers.  ISTR warnings which specifically advised users to wash their hands before smoking.

<edit>
Looked up an MSDS.  PTFE tape is harmless unless heated.  So the warning related to the risk of the transfer of PTFE from the tape to a cigarette via the fingers of the user.  Probably more likely if one rolled ones own cigarettes.

"Unheated fluorocarbon polymer product is inert, and there are rio known instances of health hazard, when handling the unheated product. When heated at high temperature, it will thermally degrade, decompose and producetoxicfumes. Inhalation of such fumes will cause "Polymer Fume Fever", which has symptoms very similar to influenza and can include headache, cough, fever, chills, chest discomfort. The symptoms do not occur until several hours after exposure and may pass within 36 to 48 hours, even in absence of treatment."

The size is not huge but then it was intended to help me cut plastic at the angle I wanted it to be cut at not the angle my scissors decided they were going to cut at

Be aware that these guillotines are primarily designed to cut strip-wood - balsa and small size
basswood etc.,and can have difficulty with plastic unless it's fairly thin. How thick is the blade?.
My NorthWest Short Line Chopper II uses a single edged razor blade and with thick material
it tends to produce a slightly beveled rather than dead-flush cut as the blade is slightly deflected
during the cut. A thicker blade would probably alleviate the problem.

I tried it out on some 40 thou which it didn't cut through but it did cut mostly through, so much that it was easy to bend and break the card with no effort which will do for me. A more substantial tool will probably be sought in the fullness of time and at the price I got this I am certainly not going to complane.

This is what I bought and where I bought it from

PTFE tape is wonderful stuff for sealing pipe fittings.  Wrap it round the thread of a fitting before doing up the joint, and it makes a magnificent seal.

But when used in high pressure, high accuracy servo systems it's a DISASTER! 

Very small particles of the PTFE, and I'm talking about particles 5 microns or less in size, can get jammed in the control orifices of the valves and the whole shebang goes out of control.

(Don't ask me how I know this....)

For that reason PTFE tape is banned in those types of systems and compression fittings are the rule of the day.

My experience is purely with the fitting of low pressure water pipes.......plumbing in washing machines or dish washers.   I know that my late father  preferred compression fittings when we installed our own central heating  many, many, years ago.  The other alternatives are STAG red lead jointing paste, which is said to be high pressure steam and chemical proof  or a revolting gunge called "Plumber's Mait" with hemp rope strands  for sanitary fittings.

My main job before I quit drafting, was to design and draft up Instrument Air Compressor module packages. The compressors came from Europe and every one of them had to be completely disassembled and then refitted for that very reason. It was still cheaper though to go this route than try to buy a properly fitted compressor from this side of the pond --- don't ask me why though ----

Use make sure you wrap it the right way.

I'd forgotten about plumbers mait.  Silicone mastic has replaced so much.
When working as a labourer one used to occasionally come across lead pipes with wiped joints.  Now there was an arcane skill.

During my tenure at YYC watching over the contractors, I noticed all the plumbers after winding the tape on, would give the PTFE tape a coat of Plumbers Goop. I asked them why bother with the tape and the answer was, it's a customer requirement ---- but we prefer the Goop ---
