My Build - I blame you lot for this....!

[Lee Roberts]

I know just how you feel Mark, only i'v not got any nails left to cut .

Cheers Steve looks good mate, dose the waste get filtered and sent back to the res or ?

Did you get my package ?

Yes Lee, the coolant returns to the tank were there is a filter to catch any swarf, also the tank has baffles inside so that any swarf that gets through the filter ends up at the opposite end of the tank to the pump pick up pipe.

Did you get my package ?

Yes I did, had to go and collect it this morning, thanks for that! Will get your couplers sorted this week and will try and have everything back to you for the weekend. Did not get round to finishing your plates yesterday as beer and other stuff got in the way, will have them done tonight though.

Also what noticeable differences have you noticed :question:

Difference cutting aluminium now is that I am cutting with a 6mm standard HSS 2 flute slot drill with no problems at all, not tried any of the alimaster cutters yet but at the moment I can't see any need to. Also it means once I set the machine running I can switch the lights off shut the door and go and have a cup of tea and a hobnob then come back when its finished!

Come on, don't be shy, 'fess up, what's the tolerance and finish like? :naughty:

Tell me I haven't been wrong all these years about the need for lots of cast iron

I'll even go first with a pic, iron cut .001" deeper than intended, biro tip for scale.

Robin, I don't think your wrong about the need for lots of cast iron for a solid machine, I did my apprenticeship at British Rail (a few years back!) and spent a good chunk of my time in the heavy machine shop operating a Noble & Lund plano mill. Bed was about 10m long x 4m wide and the whole machine must have weighed about 100-130 tonnes, 5mm depth of cut with a 15" face mill no problem at all and a nice finish, but you could still find the limits of the machine when you pushed it.

As for my mini plano mill!, I did not expect it to turn out as good as it did if I'm honest and I am not expecting miracles from it. Accuracy on the 30mm holes that I put in the plate was fairly good, measured them on the X and Y plane and they are 29.94 and 29.97 so slightly oval but not too bad. Finish could be a bit better but I just roughed them out, will have a go tonight with a 0.5mm finish cut climb milling to see how it performs and post up some pics.

Fairly good?

One or two thousandths of an inch out and he's complaining :whistling:

PS: Climb milling sounds like a terrible idea
