How much pressure needed from the thumb to crank?
269144
A significant amount of pressure is required to turn the crank. About the same amount that is required to use a standard can opener. But the handle and crank are easier to grasp for a person. I recently stopped using this can opener because I was having so much trouble getting it to open cans. I purchased a Kuhn Rikon (Swiss design) safe edge opener on Amazon. It arrived this week and is MUCH easier to use. I really like it a great deal better than the Zyliss. I like Zyliss products, but I definitely do not recommend this particular Zyliss product.

I have no idea as to the pressure would be needed pound wise, but the opener is easy to use. My wife has R/A and she has no problems.

It is more difficult to crank than a traditional manual can opener. Don't get it if you suffer from arthritis in your primary hand. You will be awfully frustrated.

It takes about the same amount of pressure to turn the crank that is required to use a standard can opener.I have recently stopped using this can opener because I was having too much trouble getting it to open cans and it sometimes leaves razor sharp metal splinters. I do not recommend this particular Zyliss product.

Yes to both. But keep the manual crank in a handy spot...you'll be using it often.

It does require some pressure... I would say a medium amount of pressure... More than I was expecting when I ordered it

I see that when my grandson plays with it, he uses the crank. Pushing it in is a little rough . Hope that helps

I held my object together pressing with my index finger counting to 10 and it held. If your object is large enough to clamp, you may want to do that and spare the pressure on your fingertip.

Depends on your strength but the taller the better. If you are too short or not strong enough a crank is $149.95

I don't find it that much work (72 years old) but the crank can require a bit of force so you might want to use the spider handle instead depending on your physical strength.

The crank is made of plastic. I don't have the answer to your other questions.

That's a pretty specific question. All I can say is that the crank sits fairly far out on the bottom bracket and I've ended up using short BBs like 118s or 123s.

Potbelly compressors hold about 125psi. Takes minimum 90 psi to operate gun. Do a good job, keep shingles straight and compressor should keep up.

The length of the crank arms- generally 170, 172.5 or 175. 175 is most common- a little less leverage with shorter lengths.

Absolutely. As a left-handed person myself, I have no problem turning the crank. I also have severe arthritis in my right thumb and this product helps tremendously. Buy it, you won't be disappointed.

You don't need that much pressure. Simply pressing it down to keep it stable and then a couple of light pulls and it starts.

I don't know exaclty, nor it is on the specs (as far as I know).Anyway, the minimum tension is quite "soft" (even for a usually non-powered pinky finger, for example) and it is widely adjustable...Hope this helpsBest regardsGiancarlo

No problem here ... index finger on bottom, thumb, with slight pressure, on middle part ... move thumb ...

all the instructional videos I watched on youtube.com specifically recommend using only light pressure. One mentioned two pounds of pressure.

I would recommend the 9". More space between the hand and crank. Good luck!
