I stand corrected on the Dake presses. As mentioned the hand wheel on this brand is only to speed up lowering the ram.
Greenerd on the other hand does offer models that use the hand wheel for applying pressure on the ram. These models have a considerably lower pressure rating than the lever actuated models
And on more research I gatherDake made ship’s-wheel handles at one time, too.
I’ve been out here measuring stuff as if I didn’t have anything better to do, because I’m trying to figure out the leverage of this import and how Dake reports a higher number.
The effective handle length in this import is a little over 22” from the center of spindle rotation to the tip of the handle. Though there is a lot of arm-waving about Dake, nobody provides dimensions.
but from the picture, it appears to be similar.
The pinion teeth in the spindle that drive the ram’s rack have about 1/8” center of engagement. On my import, the spindle diameter for the pinion and the ratchet wheel is larger than the handwheel shaft—2.198” into which the pinion teeth are cut. Half that less the center of engagement is about 0.95”, and with a spec’ed 20:1 leverage would yield an effective handle length of 19”, or about a fist in from the tip. So that all looks conservative but correct.
The Dake appears to use a much smaller pinion shaft, and it is all one diameter from the hand wheel to the ratcheting handle. If the handle is effectively also 22” long, the pinion shaft can’t be any bigger than about 1.17” in diameter, and one post on another forum suggested 1-1/4”.
Here’s a clip from the parts diagram for the Dake 1-1/2:
I do not see anything at all to suggest compound action. The handle rotates on the spindle and the ratchet pawl locks them together.
The spindle is a single diameter from the handwheel end to the handle, and the pinion gears are cut into it. If this is all in scale, that could be a 1-1/8” or 1-1/4”shaft—the square ram is 1-1/4” on a side. It has to be that small or the math doesn’t work.
The handle diameter is apparently 3/4” on the Dake—it’s 0.862” on the import.
I’m thinking the import is beefier, and the high price for the oversized spindle is less leverage. It really does make me think a longer handle would do no harm, to be honest.
I lengthened a dent rod for working on old tubas like this:
It’s a foot long and allowed the other end of the rod (onto which the dent ball screws) to reach all the way down the bell of a German Kaisertuba. I’m thinking that works much better than a cheater pipe, and lets the handle retain its flexibility.
But it’s just a hip-pocket idea in case I run into a situation where I can’t get enough leverage and the part won’t fit in the 20-ton shop press.
