    They'll be ok for what I want to use them for, not positional accuracy lol.

    Started on my clamps

    the 2 pieces will be bolted together with M4's a T nuts, then the ends drilled for M6 so I can bolt into T nuts in the 10mm track. Idea is I'll have 2 flat surfaces braced and all 4 corners. So I'll make 2 of these cost from KJN 35.

    Will only work for rectangular stuff but that 100% of what I want to cut ;)

    I ground the corners so they would sit flat when supporting the piece. They're adjustable of course so you can support any size piece and they work over the whole travel of the machine. Might add some toggle clamps.

    Now I need a good table saw to prepare the wood on.

    A table saw is the 3rd machine used to prepare lumber, after a jointer and planer, or whatever you guys call them over there. (surfacer?)

    I want the surfacer ASAP (We just call them planers or sometimes thicknesser's) but my supplier for timber supplies it surfaced both sides so I can put it off for a little while.

    My friend also has a really good one I could borrow at a push but it's massive 3 phase thing so don't fancy trying to move it but he has offered to lend it me more than once. He also has a window making table saw I might buy off him which has crazy travel and full slides all round with dual blades for cutting laminates. The problem is is far too big lol, I have considered a vertical wall saw as well B&Q style.

    One clamp is finished but not got enough m4's 20mm to finish the other one, need a trip to toolstation.

    You can see how I intend to do it though, hope it works ok ;)

    There's a 7mm gap under the clamp at the moment but going to drop 6mm MDF on top of the 18mm so the gap will be 1mm. I'm also considering ways to apply downward pressure in all 4 corners as well for maximum clampage ;)

    My ballscrew came (3 weeks, no import tax) it's a lot heavier than the 16mm ballscrew it will replace, the motor on this axis I recovered so unsure of nm but it's the same size and weight to within a couple of grams of my 2nm motors. It's a 2010 screw with BF15/BK15's I have to have a good think if I should fit it to Betty or use it for an 8*4 build. If I do use it on Betty I'll play it by ear if I need to upgrade the motor.

    Clamps are working nicely now ;)

    Going to use Knurled head bolts so I can adjust tool free, will greatly reduce the time needed to set the clamps up.

    These are for the T slot corners
    https://www.ebay.co.uk/itm/M4x25mm-C...EAAOSw4HNaTqx1

    These are for bolting into the frame of the cnc
    https://www.ebay.co.uk/itm/282550095914

    will slum it with A2's and an allen key until they arrive.

    Also will change the 2020 on the bottom to 2040 this will let mill closer to the edge of the part

    2 flute carbide end mill, what bit do I need to get a better finish (Ripping) or it speeds? This piece of wood is at least 60 years old mate found it in a pile of wood his dad bought in the 1950's at auction. This piece of wood was far from flat lol. This is only pocket clearing with no finishing pass.

    Also ordered a few
    https://www.ebay.co.uk/itm/262649813967

    so I can have the most common collets I use fitted to save time when swapping tools.

    I dream about the day I get to have these problems :D
    This is just a guess but have you tried a downcut bit? As you are not cutting straight through it should leave a good finish on the topside?

    As Robert said ,down cut bit, slower feed and............ put self adhesive tape at the side you cut, after the cut remove it and you will have a cleaner cut.
