Hi All
Not new to the forum but a new project.
I want to build a router with a table size of approx 1800 x 1250. My plan is to use 100mm square tube for the table base. I was thinking of welding 10mm x 100mm flat on the table area in four places and the same to where the linear rails will run for the gantry. (Please see picture attached). I was going to then get the plates ground so that the table is running perfectly with where the rails will bolt.
After loads of phone calls to various machine shops I am struggling to to get this machined. Very limited on who can do it and the companies that can want what I consider too much money.
I have scanned this forum and many others trying to find another way to fit the rails so that they run perfectly with the table but haven't found anything. There are loads of suggestions just to skim the spoil board but this makes no sense to me unless your rails are perfectly aligned and flat in the first place. EG If you have a 0.05mm bow in your Linear rail so will the table. Or if the opposite rail is not set to the exact same height there will be inaccuracy aswell.
I have also read about the use of lasers but again very expensive and the cheaper rotary lasers only have accuracy of +- 0.3mm /M.
Any suggestions would be great or point me in the right direction of a thread that has covered this.
Many Thanks
Mick
