I am looking to build a lowrider v4. I was thinking making the Y rails 120” since that is the length they come in, any issues or changes I need to make for the extra length? I was probably going to make the X rails 57-60” to give me just over 50” in width to work with. I don’t need to oversize th…

Y can be infinitely long, you’ll need to adjust for the curve of the earth and negotiate some treaties with other countries though. The more rigid your x, the faster you can go. The more oversize you go, the slower youll want to move. I’m using a bauer router/makita knock off. Spindle are doab…

The rigidity goes down with the square of the length of X. So half the length in X is probably close to 4x more rigid (in that dimension). But the machine is a balance and you should be happy cutting sheets with a 50" work length in X. Y doesn’t matter as much. The trouble there is mostly the space…

I have the space, I want the area under the table to be able to hold 4x8 sheets so a little oversized will work in my favor. I am thinking to build the table with rails to be able to use the full Z axis when desired but have a typical set up for cutting 3/4 material, my most likely use of the machi…

Well I guess I’ll order an extra router since they are discontinued. Welp all the parts, 2 routers and 15 end mills for $600. Now to figure out the table design… leaning towards putting it on the floor so I can cut the table with the machine.

The LR4 calculator in the docs takes care of that

Yeah, I saw the calculator. How much extra clearance is available beyond the cutting area on the y axis? Local place has 49”x97” and 60x60” sheet goods

I guess you might need to scale it up slightly if you’re planning a slightly larger than fullsize work area
