Hi All,

First excuse me for my bad English.

I'm almost done designing my router.
I want to move to practical implementation. Most things are bought. I'm left with a router bed and I have a question about that.
I thought the router bed was made of welded steel profiles. But I have concerns about welding. As a result of the internal stresses obtained during welding, there will be distortions in the structure. And they will change over time.
If there are no welds, it remains a bolted structure - but it complicates things a lot.
Please advise people who have worked with epoxy granite.
Can I replace the steel structure with a epoxy granite structure?


Please to see attached photos for sizes.
Will it be strong enough at these sizes?


Z axis: 52kg. Y axis: 57kg Total Y+Z axis:about 110 kg.
I do not have enough epoxy granite data to do simulations in solidworks.


My epoxy resin data (without fillers):
compressive strength: 60 N/mm2 (after 28 days, 23 Degrees Celsius)
flexural strength: 30 N/mm2 (after 28 days, 23 Degrees Celsius)
density: 1.4kg/l


The epoxy structure will be reinforced with 10mm diameter steel rods (rebar - inside into epoxy granite).
I can make thicker walls of construction, but the weight gets very big. However, my goal is to transport and lift this bed by several people. It is currently 150 kg (without the two profiles of 50x50mm calibrated steel. They will be dismantled).
