nither am I the bumpy bits in the main hole are the result of lengthening the large hole to make a BIG slot to allow movement two big holes with centre offset by say 10mm

Yes, but he SHOULD have milled them away so the edge of the slot was the usual baby-soft chrome-plated wonderfinish...

Bingo! That's why I think he farmed this piece out to the local chop shop. You know... The place next
to the little greasy taco shop down the road. ; )

a WEE bit more done , X motor mount finished and finished up all the work too the table ends , had to re work the RH table end as the motor was original going to go on the LH end of the table straight out ,cant mount motor underneath table on the left as it would twat Z motor , RH table end had only machined for one bearing to carry the end of the screw .

Better make a start on the Z motor mount

Anyone no how to change the position of the "Home position" on the Mach3 screen as is it is bottom left , i would like it top right ?

Cheers Rob

Looking good Rob

Cheers Mick.

Rob, what sort of capacity do you expect the machine to have in terms of cutter size and DOC on various materials? Looks like some hefty motors being used there.

doubleboost · « **Reply #385 on:** August 05, 2012, 03:50:46 PM »

Hi
Rob
That is looking really neat and compact

I dont think you will have any problems with the mountings flexing

At this rate you should have it finished to do the valve cover on my mill engine

Never gave it much thought Pete , but i bet it will snap cutter easy with me at the helm

,, the limiting factor will be the HP at the spindle .

Rob, Isn't your X axis motor seriously limiting the X travel on your set up??

I've just been measuring my 6 x26 and at the left most table position, the right hand end of the table casting, is level (within a knat's cock) with the right hand side of the knee casting.
It looks to me that your X motor will hit the knee about 60mm before that point??

This is my machine at extreme left travel

and the DRO showing the max travel

sorry about the poor photos

Cheers

Bob

Hi Bob ,in a word Nope as is I have 420mm

If i had mounted the motor direct I would of had another 65mm of travel

Rob

9fingers · « **Reply #392 on:** August 11, 2012, 04:44:28 PM »

Ok I think I've solved it. My table casting is only 610 long so more like a 6 x 24

My 426 mm travel is however at the expense of part of the dovetail not being engaged but I hope that will not be a problem.

Cheers

Bob

Rob.Wilson · « **Reply #393 on:** August 11, 2012, 04:51:07 PM »

Hi Bob , cant see it being a problem

Got to ask are you planing on making 16" long parts (allowing for tool width ) cant see me needing something that long ,and if i did I would probably get/make a bigger mill

Rob

I used to work on panels for electronic equipment in 19" racks.
I always had to re jig to do the 'other end'. A right PITA

I quite often have a vice on one end of the table and use the other half for mounting stuff direct onto the table.

I can always cope with some extra length

Not allot of actual work on the mill done this week , but i did crack out the etch a sketch and doodle up a drawing for the Z motor mount .

Suppose i better get up early the morn and zap some plate together before i get dragged to the beach for the day
