Design Study: Rail Inline With Ball Screw

[Ger21]

I am surprised to read this. Granted, my machine is a little on the small side compared to many I see here, but it will fit on an 80" x 40" machine. The going shop rate is $60/hour near me, so I am counting on all the machining work coming in just a few hundred $. Given how much money people invest into designing and building their own CNC routers, I would thinking have the rail surfaces and mounting pads machined would be easy to justify.

In nearly 15 years of reading a majority of the DIY forums daily, I can count on one hand the number of people who have had their welded frames machined.
The reasons, as stated above, are probably that most people don't know where they could have it done, at a reasonable cost.
