    When you compare stiffness there are many aspects that have to be considered. In every case sandwiched construction is lighter and stiffer than uncored structures. The final product is going to be...

    It has evolved.
  7. Re: Small Composite Router Build 1000 X 600 X 300

    LOl are you saying I should shut up and just build this thing? I tell you this last couple of weeks has been full of surprises, and most of them have been very costly.
  8. Re: Small Composite Router Build 1000 X 600 X 300

    I may start a new thread. The machine has experienced extreme design and cost creep. What started out as an exercise in building an inexpensive "good enough" machine, has turned into several...
  9. Re: Small Composite Router Build 1000 X 600 X 300

    I've had a life time of experience working with composites. I've made them considerably stronger than it would have been possible using the same weight in "Real Metal" (aluminum).
    As it turns out...
  10. Re: Small Composite Router Build 1000 X 600 X 300

    I've built several structures using both carbon and glass. Carbon is mostly useful in high load areas. The webs would not be laminated. They could just be plywood with colloidal silica filled...
  11. Re: Small Composite Router Build 1000 X 600 X 300

    Sorry my previous responses are a little out of context. The weakness I referred to was about the round rails.




    It was too thin, I fixed that.

    This project is really about Fiber Glass,...

    I'm switching out the SBR20s on the Z and Y axis to EGR25s plus I added 100mm to both so I can have some extra space between the blocks.
    Images coming.
  13. Re: Small Composite Router Build 1000 X 600 X 300

    The collet can touch depending on how you have it mounted. Drawing are coming soon.

    This keeps getting better. I opened the package and what do you think I found? LOL
    Flex couplers equivalent to something you might find in a printer.

    The ones I just order are rated for 12.5...
  15. Re: Small Composite Router Build 1000 X 600 X 300

    I agree with you guys 100% about this not being strong enough. The system is way out of balance. The problem is the budget. The saving grace is that this is a very small machine.

    I just will...
  16. Re: Small Composite Router Build 1000 X 600 X 300

    The Table will be a wood product composite, that I will do a report on during the construction phase. The Gantry will evolve into a molded, cored, Fiber Reinforced Epoxy, which will be fiber glass...

  18. Re: Small Composite Router Build 1000 X 600 X 300

    Thanks Gerry,

    I couldn't agree more. But this little machine is going to be used primarily for making wood signs. I am going to try cutting some aluminum as a test of accuracy under heavier...
  19. Small Composite Router Build 1000 X 600 X 300

    I couldn't tell you why. Maybe I just like to do things the hard way, maybe I like the looks of things built with composites.

    Maybe, we'll see, if I'm just another dreamer.

    Re: Good Lead on Power Supply

    Thanks for the tip,

    As you well know, Unregulated Power Supplies can momentarily go beyond their rated output. These claim 200% for a few minutes. This will allow for a smaller one to be used. ...

    Good Lead on Power Supply

    Any one have a suggestion for an inexpensive power supply.

    I would like a 48 volt through 60 volt 30 amp or so.

    Thanks

    I watched a few videos. And after viewing them I decided to build a small CNC before I make the large one.

    Thanks Gerry and Robert,

    That last part, whatever I am "familiar with". LOL, What I'm familiar with was used by dinosaurs. In the late 90s I converted a 54" knee mill to cnc, including replacing...
