Here is what I believe to be a New Product Announcement:
I hope many of you will benefit from the knowledge of this device, the AMAZING QFC = Quercus Ferrous Clamp.
Quercus and Ferrous have literally been around for thousands of years and are some of the few makers that date back to biblical times!

Quercus and Ferrous have recently teamed-up to create this amazing product! It is one of the handiest products I have ever used. My clamp is the 24"x16" model/size and all I can say is WOW! I have used clamps of this mechanism style for years, but my previous one was a light-duty model (from Liriodendron) that was permanently attached to a workbench.

If necessary I am glad to provide further information, but herein I am posting some photos of mine. One of the cool things about the QFC is that it is capable of rapid-action. With the proper accessories, the QFC can be utilized in situations where other vises or clamps simply cannot do the job. One of my hobbies is making various types of abaci (Chinese Abacus, Japanese Soroban, Indian Iota, Slavonic and Classroom Abacus). An available accessory pack (which I have and recommend) is comprised of heavy wooden blocks in various sizes - which have sizes which allow the operator to choose clamping pressure (tight, light or the popular medium) via length, width and height dimensional variations that enable operator to simply rotate the blocks to adjust for space requirements. (Example 2" x 3" x 4" block pairs)

Each Quercus-Ferrous Clamp is custom-made and I ordered mine without handles, because this enables the device to be easily transported and sat on a workbench or floor on the top, the underside or any of four choices of sides.

In order to better document this product, I will follow-up immediately with additional photos.

Ah, those Quercus and Ferrous guys never cease to amaze do they? Quercus on his own has some pretty strong stuff but when he and Ferrous get together it's just sort of magic. Now, show us how the thing works. I'm having trouble figuring it out.

More photos of the QFC!

As promised, here are some additional photos...

Dimensions are indicated on the attached photos, and there are also some close-up photos showing that all bolts (3/8-16) are begun and ended in counter-bored holes.

Also note that on the side (I called it short) where the parallel oak (Quercus) members are 16" long - there are small (3/8-16) knobs. These knobs spin about steel (Ferrous) threaded rods and receive resisting spring pressure via steel (Ferrous) compression springs. The central moving segment is drilled with slightly over-sized holes and approximately 1/16" of the central segment's underside has been removed to minimize friction across the MDF multi-funtion deck.

Also note that on the side (I called it long) where the parallel oak (Quercus) members are 24" long - there are large (3/8-16) knobs. These knobs spin about steel (Ferrous) threaded rods and receive resisting spring pressure via steel (Ferrous) compression springs. The central moving segment is drilled with slightly over-sized holes and approximately 1/16" of the central segment's underside has been removed to minimize friction across the MDF multi-funtion deck.

The manufacturer utilized Kreg Square-Drive Screws into counter-bored holes in strategic locations to prevent interference when central bars are in-motion. All bolt heads, washers, nuts and threaded rods are within the exterior confines of the 24" x 16" overall size - so this device does not make scratches on workbenches or floors.

I hope this NEW PRODUCT REVIEW proves helpful to those of you that are contemplating the addition of one or more of these devices in your workshop!

Quercus is my favorite of the pair. But, Ferrous comes in handy. Especially when teamed with cousin Ductile.

Oliver,

I am glad to have you participating! Q & F (as you have noticed and pointed-out) are both strong in their own rights - but working together; who knows what their research department will submit to their product development engineers! Certainly their initial products have stood the test of time - so I feel confident that they will work in unison in sound business practices!

Using these, of course; requires a specialist - therefore these certainly would be useless in the wrong hands. The device comes with a well-written set of instructions. Joy is on-vacation this week (how did you ever guess), but I am here "holding-down the fort" - so for you, I will make some more photos showing the "rapid-action" capabilities as well as the merits of the non-cubical blocks being utilized in this state-of-the-art device.

For the balance of tonight, Molly and I will be watching Animal Planet!

Gene, you are so right! Ductile wanted to be a "Silent Partner", but you can sure bet he is constantly pressuring his partners in this effort!

QFC = Quercus Ferrous CLAMP
Occasionally woodworkers need to work on something held in a fixed position. This device fits somewhere in the zone between clamp and vise. Quercus and Ferrous both have realized symbiosis in working together, but realized that without Ductile (a silent partner), their device had a few strategic hangups. Often woodworkers have need to give solid, yet undenting grippability to hold workpieces in an endless array of working postures. Yes, Gary it is an unprecedented clamp / vice. And Dave, you were clever to notice that nobody really knows what is "up" and what is "down". In the most literal use of the product, there is honestly no "left" or "right", nor is there a "front" or "back". It does have, however; definitive faces. The ends and edges are kinda like a compass, in the sense that when this product is rotated, the ends and edges switch positions - but it can be configured (without tools) to be whatever one needs to meet their individual woodworking needs!

From the photos (in earlier posts to this thread), one experienced in quality, high-tech woodworking may notice that an experienced operator need-not be hampered by terms such as horizontal or vertical - This device is literally both horizontal and vertical, with numerous options in-between!

Since there is no rigid attachment to a workbench (without traditional C- Clamps), this is a go-where-you-need-it tool! It can be utilized in a workshop or on the road at a jobsite! Best though, to keep it under cover; and out of the rain and other forms of precipitation - this is to satisfy WARRANTY CONDITIONS... Quercus claims it to swell where wet, whereas Ferrous claims it to rust when damp. Ductile (the silent partner) remains silent - and although he provides constant pressure on both of his partners, he tends to side with Ferrous in consideration of the corrosive potential. Remember, these are WARRANTY CONDITIONS. MDF - the supplier of the Multi-Function Plate states that adverse weather conditions can be a cause of accelerated weathering with buckling.

With vises and / or clamps made from metal, there can be a deformative factor as a result of over-pressuring the jaws of said competitive devices into faces, edges or ends of aforementioned workpiece(s).

With the optional pneumatic assist kit, this QFC can be clean and ready-to-go at a moment's notice for woodworking projects done by beginners, novices and even the most experienced woodworkers.

As an added bonus, Quercus Ferrous Clamps are available in metric sizes as well as the (old stand-by) Imperial sizes (I have the 2416). All units offer pressures that can be accurately measured in pounds or kilograms with a simple change of scale or mathematical conversion.

I hope this helps many of you woodworkers out there that are considering adding one of these handy state-of-the-art pieces of highly functional equipment to your tool collection.

Fred, the QFC is a world-wide product line! Veritas is a fine tool manufacturer, but Quercus and Ferrous have a solid reputation that dates-back far prior to Veritas even being a twinkle in the eyes of their founders!

Theo, That is an excellent point! Not all shops are color coordinated in such a way that this could only be available in one color scheme! Personally, since a lot of my work is just making kindling and firewood - I chose the "Natural Color Scheme". Just be mindful that Q&F haven't been "around" all these years nor have they been as well-known as they already are without customers being able to select from a wide pallet of color options!

Note: If you are at all concerned about durability of these tools, just remember that Quercus and Ferrous products (prior to the partnership) have been around for hundreds of years, and Ductile (the silent partner) is always going to force his partners to go in the right direction!

Noah used a QFC when he built the ark prior to the Great Flood!..and Moses is reputed to have used a QFC to hold the rocks for the 10- Commandments to be carved!

I hope this helps!

I want to see a video of the item in action, on Youtube, by an expert, before I put in my order.

Also, with Theo, I want light blue......

Would someone please have a link to any of the two (three) manufacturers to see this in the web?
Asked papa Google, and couldn't find anything :sad:

Thanks a lot

Martin, Google can easily point you to Quercus or Ferrous, however; QF is so old that they have never needed to use that medium. All of their products have come "full circle from the ground-up".

Neville, Thank you, I've been using these for several years - initially something that I built to satisfy a need in my Abaci Manufacturing. Turned out that I was finding myself using my permanently mounted initial unit quite a bit for projects having nothing to do with making abaci. Several of the guys around here had commented about how nice it would be to have several - in different sizes. The original one was Liriodendron & Ferrous - (Liriodendron is very straightforward, but told Ferrous that he just "couldn't hold-up under the pressure". It worked well for several years, but didn't have the "Corporate Strength" as it now does with Quercus. Ferrous was literally extracted from the Liriodendron Partnership and formed an immediate assembly with Quercus. As I say "Tweak Everything" - there is always room for improvement. I have been their corporate prototype builder for many years and it is a relationship that I expect to last very long and be passed-down through my heirs!

Very soon, I will be posting some photos of my accessory package's contents, which had been back-ordered. I think they will be here today.

Pressure partner? I thought that was Ferrous' job.

Steve, you are correct! Ductile is the main pressure applicator of the group. Quercus and Ferrous without help seem to just stand around, but when Ductile (the silent "pressure" partner) came "on board" - it just seemed to get everyone else moving in the "right direction". There is some muttering on Wall Street that Manganese and Cobalt are investigating getting involved as well.

I kinda like the 3- way partnership as it is now. I am afraid if Manganese & Cobalt get involved it will just elevate their overhead costs. M & C have made no secret of the fact that if they get involved it will require a union.

I have to go to a lunch appointment, but when I get back I hope to post some photos of the accessory package (it arrived via FedUPS earlier today) - to show some of the versatility this unit can provide! I am so excited I hope I don't choke on my food!
