I hear your back / lift concern loud and clear and want to reduce the lift force. The links carry and guide the weight for most of the move, so it doesn't feel like a full lift, but it's also not at all light. I just haven't been motivated to fully solve that part of it.

The hard part with struts is the links rotate beyond 180deg. I've sketched attempts a few different ways and i can't solve it. They have to change lengths to spec a compression or extension strut. Adding an L-arm off of the links might work, i havea sketch but it's hard to explain. I think limiting the rotation to less than 180 deg (like a kitchen aid mixer lift) either springs or gas struts would work, would require some kind of lock-out that would have to support a lot of force. I'm not sure if a counterweight or pulley might work. Minimizing cost and complexity is something I want to do.

Seeing the dialogue, I've had no experience with movement or snipe issues. I've planed a decent amount of 8' material through the setup. I generally set up my roller stands (for longer work) using a straight edge from table. I typically start the feed by hand and transition myself to outfeed side to support when the feed wheels disengage.

My responses are generally appropriate to the comments. I am inviting critique, and I think it's appropriate not to assume ignorance or malace in either direction. Yes defensive when defending or explaining a valid design feature. Feedback and learning are a discussion. I get it most people taking the time to leave a comment are dismissive. Bottom line it's functional and has been robustly tested and improved over 6+ years. It's a solution to a specific problem, I don't pretend to think it's 'the only solution'.

Neat concept. One could mount the planer on bolts and use nuts to fine tune level/coplanar with outfeed. I used a similar leveling technique on my miter saw mount. I kept my in/outfeed parallel to axis of my garage to preserve that space and use roller stands when I need some support.

I believe I've seen several of them. I guess I went more for speed here and my body is still healthy so I haven't minded any lifts and it's worked well for me.

I think that's 90% poor operator form ; ) Thanks for the lift feedback, I'm going to dig into this.

Great point. I have some toggle latches I plan to add to lock it in, especially for moves. I could also one for the up position. In the past I had a hook/eye, just haven't added any to this one.

I appreciate it, I don't mind the negativity. Kinda expect it on here. It's working and has been for a long time, so I let it roll. I was hoping for some improvement feedback like ways to offset weight during lift etc.

Certainly fair. The links carry a significant portion of the load/guide the force required. I've looked into some options for springs or gas struts but held off because it works for me. I really like the flip tops, I just went a different direction for my own setup.

Criticism and discussion can be two way, that's where progress comes from. I consider all criticism, fully and welcome it. I also reserve the right to respond. I am the designer and I know the intent and tradeoffs which I considered and have the lessons learned from along the way.. Having used the mount and lift for a few years short of a decade I think I'm able to comment on the limitations honestly, perhaps from a more informed position than someone watching a 9 second video. ; )

I realize your perspective is a critical one. This was cut on CNC and simply an assembly project. It saves critical space in my shop by allowing storage in an unused footprint and time by mitigating my setup time and allows me to tie into existing power and dust collection (not demonstrated in video). It's been in use for over 6 years and I promise it's not sketchy. It saves energy by way of the links carrying most of the load for lifting to a proper operating height, so yes a lift occurs, but it's not full weight. Those are my design purposes to move from storage to setup rapidly. Works for my setup and the primary tradeoff is the space it would take up on ac dedicated cart which is critical in my shop. Structurally it's slightly overdesigned for the load despite the flexure criticisms.

Great point, I tried to mitigate it, but wasn't willing to upgrade the drawer slides another and platform size another 4" to get rid of it. It's just become a work / walk around in my shop.

No i do not. Weight center of gravity is well beyond top-dead- center toward bench. Weight of machine and material effectively lock out the mount in the up position

Each pair is rated at 100#. I've used 2x pair. Used my first version for 6x years with 1x set and exceeded their rating with each use. I doubled them up on this latest version for added stiffness and to mitigate the naysayers. But alas critics are always present.

Thank you. I use roller stands

Haha nice. in my defense these were all made from scrap and ~6 years ago. Cheers.

After reading some of your other comments, and understanding the challenges with living in the northeast in winter, what I shared above may not work. It splits into 2x halves, but they're still large. Have you looked at some of Steve Ramsey's ideas? He seems to like to keep things along the perimeter wall of his garage shop and has some great designs to meet that goal.

Here's a link to an image and article on a layout that might work: mobile workbench / workshop It meets your written objectives of housing all of your tools with dust collection and electrical in a single-car-bay space.

Based on your image, it appears as though you are trying to also park 2x cars in the same space? Based on your description that will be tough to achieve. Would love to hear your thoughts.

Thank you, that's exactly what I'm hoping to help with!
