I added a drawing and some notes here for those interested in some of the details. This is not a tutorial (and not intended to be), but it may help those with some ideas for building something similar. This sort of project always works best if the maker is willing to do some intelligent experimentation. Good luck with it! studio.kzbin.infoUgkxvkbQ0WoLqJrQJzkEJVmyaRJQ4K0aXKS3/edit

Sorry, I have not done the calculations. Because it is a double lever arm though, and with the approximate locations of the hinges on those lever arms, I think the applied force would be 3-4 times the downward force applied. You can get more (or less) force by extending the length of the lever arms, or shifting the position of the hinges.

Great! Glad that it helps. As long as you use a dense hardwood (maple, oak, ash, hickory, or similar) for the struts, you should be fine. Also, it will be important to use some heavy-duty hinges and perhaps adapt the way that they are used. (I just used some exterior galvanized strap hinges that I had hanging around, but any heavy duty strap hinge will be fine. I would use strap hinges just to allow good connection along the length of the struts. A key adaptation: At the lower-stress hinge points (2 of the hinges) I just used regular lag screws to fasten the hinges to the wood struts. But the other two hinges are potentially higher stress points, so I adapted the holes in the hinges a bit and then used through-bolts with a lock-nut (or lock-washer, and nut) to secure them to the wood. I have posted a picture here to show that: yt3.ggpht.com/Vh6uaCnmIGQloCFZJajai2AbWJQ09nY7NRAkayiwpEKjrdWnx_bsYgDp58Bxsq0bvxtzZ0rhy05u-A=s1600-nd-v1 Have fun building yours. Bon chance!

@@MrHolz1234 thanks for all this helpfull informations, and the link 😊 Have a nice day, bonne journée!

Thanks!

Sure, unless it interferes when the press platen (plate) when is lifted that sort of modification could be done if it is helpful. I don't do print-making, and this press was for my daughter-in-law. So far she has been happy with it. She also has a Woodzilla press which is a similar style that is made with a metal frame. The Woodzilla and other similar brands do not use any sort of stabilizing cord, but I am sure one can be attached if people find it helfpful. Thanks for the comment.

For whatever reason she and many others preferred a lever-operated press like this for their linoleum-block and wood-block prints, so of course that is what I made. (She had a deep aversion to roller etching presses for some reason). The wood struts in my design are well under their load capacity and the press is not in any danger of failing after many uses. I agree a simple hydraulic press would probably work fine - although slower opening and closing. I think some of this may be simple esthetics, and the hydraulic press and roller press apparently lack esthetic appeal for some. She expressed an interest in a "Woodzilla" style hand-press, so that this project is about.

I did not find that it worked for my needs with a brief test. So I returned it.

It got me up that very small hill with no pedaling after a full charge. It was not able to get me up the hill a second time. Although it still has some power left after going up the hill, and would assist pedaling on flats, it was too limited for my needs.

I just went to the Jaxpety site on Amazon, and it appears that they do have a button for front tire option. For some reason they do no show a picture of their front tire though, so you need to confirm that it has at least has 6 mounting holes where you can mount one (and apparently buy that disc separately - standard disc are cheap, and you can easily take it off the bike front tire that you purchase and switch it on to your hub motor tire). Two of the reviews indicate that a standard disc ring can be mounted on the front tire, but one says that it will not fit all disc systems. So, you may have to be prepared to purchase and send it back if the disc brake location is not compatible with what you get. Or alternately if you can add in spacers and spread your forks a little for adjustment, you can probably make it fit. Don’t get the rear kit that they show the picture of as this would be the wrong kit if you want to use this for a front tire with a disc brake. You don’t want the one with gears. Understand that on some bikes having the power in the front is not as desirable, but for my system with the kick-bike, it works great.
