HM adjustable Direct Drive review.

looking at the slope back side of the machine body.. were are you securing the rubber band? Really high were it doesn't do much good? would be good to see some rubber band horns on this..

I have a Kubin Direct Drive.... And love it for color packing..... I really want to get one of these.... I think this is going to be my next adventure

Hello guys, sorry for re-take the post, but i recently have in my hands a HM DD and there´s something i don´t really understand. First of all maybe it´s just me (coming from coils) or the question can be silly, but...

I am looking at the rotary, it seems to have some strips on the top of the excenter and also one on the top, that´s ok. But i move the top part, lightly unscrewed just to know how many distance it has from closest stroke, to longest, ( the cam has a carved hole with it´s own limits, so i try to find each limit side) and i only find 2mm. between each point.
So, assuming the closest point to the center gives me a 2.5 mm. stroke... i have only 2mm. of play wich means 4.5mm. the longest stroke. How can it be 5 or even 5.5?

Thank you, maybe another HM DD user can give me the answer ;)

You can adjust it past the "strips". Each strip is a measurement of MM's. The first is 2.5, the second is 3.5, & the third is 4.5. I'm pretty sure that you can move the slide past 4.5.

Thanks serial1313, yes i can move beyond the carved hole, but i suppossed somebody made it with a purpose... And if i do it i´d be screwing out of the "carved cut" (sorry, don´t know the right word) and would be screwed, but unbalanced...
I´m talking about this:

Attachment 25895

And these are the measurement strips, from limit to limit:

It will go to 4.5mm fine. If you go further than 4.5mm there will be a LOT of side to side movement with needle bar. That is why it only goes up to 4.5.

you are right that you can only slide the moving part inside that slot slightly over 2mm ( in fact 2,39mm .... )
but i can see that in your mathematical calculations, you are not keeping in mind that you are sliding that moving part while the excenter is still... if you slide 2mm ... we are talking about off center.. .... when the execenter actually turns you are actually get a 4 mm difference...
total stroke length is the language we want to talk about...

thanks, Roman

I want one of these soooooo bad,,

Yes Roman, thank you, you´re right. My measures are only the radius, and the stroke it´s actually the diameter. Thanks for the explanations ;)

I own 2 of these machines, I have only got the chance to use it once and it was absolutely amazing for soft black and grey BUT my griffin tubes from eikon wont tighten in the vise? I have no idea whats going on? I cant even get stainless to tighten inside them either.
