I want to upgrade my CS-88 manual underpinner and have narrowed the search to three. I am in Canada, so bringing a unit across the border adds a couple of steps and a couple hundred dollars. So far, the most expensive is a VN-42. Nearly new but located a long way away. Next is a Fletcher Corner Pro 5600. Brand new, never used but purchased quite a few years ago, and located in Canada. The least expensive is a VN 2+1. It is "well maintained and rarely used". It is about 6 or 7 years old. I am a home based business that started as a hobby, but is taking up more and more of my spare time. Picture framing may turn into a full time job when I retire from my current occupation in a few years. If anyone has any advice or opinions that may guide my decision, I would be interested. Also, if you have a good used machine that you think may interest me, please let me know. Thanks
 
Where are you in Canada?

Have you asked your reps/distributors to connect you with frame shops in their territories that have closed, or want to sell off equipment?

If you're close to the border you can have an American piece shipped to a Fedex/UPS counter in the USA, and then broker it across yourself.
 
Theoretically, these are all good machines. However, a Red Flag goes up when someone tells me a machine has never been used.

Why did they buy it then? Also, a machine that doesn't get used is often more prone to issues than one that gets used moderately, but not abused.

When buying used equipment, you need to either see it, touch, and if possible try it, or you need to rely on the reputation of who you are buying it from. IMO, you probably shouldn't have to go outside of Canada either, in order to find what you are looking for. Be patient and you will find a fair deal.
 
VN 42

"...a machine that doesn't get used is often more prone to issues than one that gets used moderately, but not abused. "

Paul,
Is this a statement of fact... or an assumption.
I happen to have an unused (still in the box) VN 42. What in particular is known to malfunction due to it not being used?
Also, is there a difference between a machine that has been used and then goes for a long period of not being used vs. a new machine that has never been used.
If/when I happen to sell it... I certainly don't want to mislead a prospective buyer.

Seals can dry out and become brittle. Since it is new in the box you should be fine as long as you haven't been sitting on it for 10 years.

I just replaced the driver cylinder and seals on mine and white grease it used to lube these parts. Once it has been used for a while if it is not lubed with pneumatic oil the seals have grease worn off them putting them at risk.
 
Lubrication of pneumatic cylinders is supposed to be done from the inside, not from the outside, by adding oil to the input port for the air supply. The best way to accomplish that is to install an automatic air filter/lubricator, which also cleans and removes moisture from the air.

Pneumatic supply air should be clean, dry, and lubricated at the machine, or within a few feet of it, because air pipes/hoses will shed interior debris as they age, and will condense moisture on the inside.

Z, the simplest thing to do is to take the machine out of the box. hook a compressor up to it and make a video that shows the v-nailer in operation. This will benefit both you and the prospective buyer. The Buyer gets peace of mind, and you increase the value of the item you want to sell. Neither of you would want to ship a machine, only to find out there's a problem.
