At that time i had an overly heavy sled with a huge router. The double pipes were intended for more stability and i wanted the router in the middle. I did find a cheap an simple solution for bearings on the internet, but moved to a spindle and much lighter sled, so did not follow through with this idea.
Check out maslow-mark-II-3d, similar and much better, plus panel-saw options.
With c-beam and spindle, the sled is so light, i’m looking for a ‘light-weight’ option now and might target curtain rails. Still all just in the head.
Kind regards, Gero
