Gym Equipment (Wood)

[Medeek]

So this is a little off the beaten path for me, usually I am posting about one of my plugins, but here goes anyways.  Since Covid started a couple years back I've had to give up on going to the gym and instead have managed to cobble together a fairly decent personal gym in my garage.  I've got a treadmill, a couple benches and some dumbells and other free weights.  It actually isn't too bad of a setup.

The only thing I have really been missing is a decent lat pulldown machine.  I was about to purchase one on Amazon but after reading a lot of reviews it seems that a good quality machine will come at a not so good price.  That being said I thought it might be interesting and fun to try and build one instead with my teenage boys (get them off their games for once).  Here is my first crack at a design:



My biggest issue or concern is rigidity and stability.  Don't need this thing toppling over on me or one of the kids.  I also haven't shown the hardware in the model yet but it will be pretty simple, a couple of pulleys, wire rope and the 10 lbs pulldown bar.

The link to the model is below if you care to take it for a spin:

P.S.  When it comes to strength and rigidity my concern is largely due to the amount of weight I typically pull (120 - 175 lbs) on a machine like this.  I will probably construct it with glue and screws, but it may need more bracing with OSB or plywood.
