When building DIY-CNC Router Table Machine, accuracy,straightness & position of axes depends on quality frame and mounting of linear ways, leadscrews. How about outsourcing some of this work to local shop?. What would be the cost of that? Your opinion please...

Whatever frame you`re using it would be great to have trurly parallel and accurate surfaces(sort of master edge?) for mounting linear rails and leadscrew blocks. One could use any type of cheap thick aluminium or steel plate and mill "shelves" for THK type rails and leadscrew blocks to 0.001". Both rail would be in exact same plane, inaccuracies removed.

Z axis and Y axis would look and perform more like these expensive linear stages mounted on special plates, complete with leadscrews, etc(hugely expensive).


So question is how much will the local shop charge? Couple hours on medium size mill with DRO, within 0.002" (or better). Router envelope 3` x 6` or larger. Plus basic drilling for rail hold down bolts. Aluminium plate or mild steel or whatever scrap metal frame you can find and use in DIY CNC Router.

Thanks
