1.5ton manual clicker press

[DieselTech]

Guys & gals I'm looking at a 1.5ton manual clicker press. My question: Will a 1.5ton manual clicker press cut out a 10" x 4" wallet back? Or is this wishful thinking? 

Thanks. Any & all help will be appreciated.

To help you decide I used the following formula when calculating my tonnage needs for a clicker press.

F (pressing force needed) = S (shear strength of leather / 2) x L cutting (running) length of die X T (thickness) of leather in inches X Sf safety factor

Example for 10 oz leather with a 3 inch square die.

S (shear strength of 10 oz leather) = 2900 psi

L cutting (running) length of die = 12 inches

T (thickness) of 10 oz leather in inches = 0.156 inches

Sf safety factor = 2

F = 1450 x 12 x 0.156 x 2 => 5428.8 pounds (pressing force)

So the question is the manual clicker press rated in Imperial tons or US tons? Also what is the price of the manual clicker press.

5428.8 pounds = 2.42 tons Imperial tons, 2.71 US tons

So the question is the manual clicker press rated in Imperial tons or US tons? The reason being 1.5 US tons equals 3000 pounds while a 1.5 Imperial ton is 3360 pounds.

Whether or not the manual clicker press will work is going to depend on both the bed size of the manual clicker press and the thickness of the leather.

I decided not go the manual clicker press route even though a 5 ton probably would have done for the main reason, Money. A 5 ton would have cost north of $3000 Canadian and would have been a one trick pony. That cost versus converting a 20 ton hydraulic shop for about $700 Canadian total including cost of the shop press when I'm finished. Hum. I'm at about the 75 percent completion mark.

Simple answer is Yes. My 1.25T  Tandy press  will cut that, but I'm restricted on the area size and I have to move the leather/die around to do it in stages

Dang kgg I'm going to need to go back to school. I thank you for the detailed formula. 

But the press is stated as 1.5imperial tons. & has a 14" x 10" cutting platform. 

Thanks I appreciate it.

Thanks fredk how do you like the tandy press? I was looking at a vevor press, due to limit funds at this point.

I have the more expensive press, the model before this one but basically the same;

https://www.tandyleather.world/collections/machines/products/tandypro-r-hand-press

1. I got it in a Tandy sale several years ago, and 2. I had some money come in otherwise I'd not have bought it but I'm glad I did.  I like it a lot. I use it all the time.  dunno what I'd do without it. I use it for 3D/letter stamping and as a clicker press. Next is to sort it for sewing hole punching 

One thing about it though; there is a 'pad' between the arm and the ram and this wears down. They don't tell you about it and you cant buy replacements. I bought a bar of delrin and cut enough discs to last me a few years

Thanks. I appreciate it. Well if I done my math right. It appears it would take 2900lbs to cut my wallet backs. Lol that's if my math was correct.

I just cut a 5.25 x 5.25 inch valet tray out of 1.8mm chrome tan and it cut easily, it even went through the cardboard that I was using as a backing

Thanks. Do you think for wallet dies, I should get them with the stitching holes in the dies? 

Or should I get the dies without the stitching holes? 

I also imagine the press could be used for leather embossing as well. 

I appreciate all the input. Thanks.

Do the math again including the total running length of the holes. Including the holes and depending on whether the holes are punched or perched that may put you very close or over the 1.5 ton rating.

Yes you should be able to emboss quite easily.

I would get a stronger press.  Harbor freight sells em cheap, and they're solid.  I got one round here is.. I think 6 ton (?)... small enuogh to put on a bench.  Big enough to cut your wallets.  Mine used mostly for small holsters, mag pouch parts, drink coasters....

I'd have to look up the "sae" formula for press tonnage, but it would involve the cut length... so a 4" x 4" drink coaster would have a 16" cut length.  You're talking about more than twice that.

I'd do it WITHOUT the stitching "holes", becuase I do not like stitching HOLES.  YEars ago, Tandy sold those little "kits" (which I HAVE used on occasion) with holes - and it sucked   Doesn't look right with thread OR lace, and weakens the project too much.

But yeah - you can emboss with a press as well.  I use it for my "maker stamp" and also for small dies pressed into drink coasters.
