Thread: Very simple milling job required

Hey Ken,

If you have a vice and a hacksaw, why not just saw off the excess and sand the mess smooth on a sheet of alox paper.

BT

Hi BT,

I have considered all the options, a simple milling process is the go.

Anyone, anyone, there's a slab in it for you.........

If only I had my Arboga up and running...........

Ken

neksmerj, if you don't mind a drive to Healesville, about an hour i spoze,

Hi Ken
You'd have to be unlucky but I cant fit you in next Thursday.
Be quicker to post them to me if it suits.
Quicker still to get that damn mill going!

Do you have a lathe? (I can't remember if you have mentioned it or not in other posts/threads) If yes, will it swing 120mm dia? if yes, why not set you guides up in a four jaw and just face the back down to the thickness you want? A bit of mucking about because the plastic is, well , plastic and so will deform a lot easily than metal but still I reckon it would be doable.

Ken,

Have you thought about using a router? Clamp the block between a couple of wood parallels which will serve as rails for the router base and use a router to skim off what you don't need.

Ken going by your drawing and your comments something appears to be wrong.

If the base is per the drawing at 15mm and the finished size is now 4mm that would suggest an 11mm difference,you have asked for 7.6 mm to be removed.

Did your mate charge between $40.00/$50.00 plus material for this job.

Thanks guys for all the suggestions.

Pipeclay, nothing escapes your eagle eye. The finished blocks were machined undersize to suit the acetal the machinist had on hand.

You are also correct about the pricing.

Stu, I may be in touch.

Ken

While we're picking on the drawing.
Don't double dimension(now is that general practice or just something I picked up along the, anyone?)
and who called out +/- 0.1mm on a door track?(unless of course its needed )

Everyone's picking on me. Stu, double dimensioning is not the norm. In this case, the dwg was sent to an apprentice to program a cnc mill. I wanted to leave no doubt with the dimensions. All the dims went out the window anyway when the machinist decided to reduce the overall size to suit the acetal stock in hand.

Win some, lose some.

I'll often double dimension my own drawings although it is normally on a stock preparation outline. It's a technique I use for reducing the forehead redness that is caused slapping it to often.

I do it. Better too much information than not enough.

HUH ???. What sort of machinist is this bloke? Obviously I don't know the full story here, but just going on this, then the "machinst" should maybe consider doing something else. If someone is paying him to do a job and supplies a drawing, then its not up to the machinist to go and change sizes if he doesn't have the right sized material on hand.


Imagine going to, say, the local tyre store to get a set of four tyres fittedand when you come to pick up you get told "we only had 3 the same size so we put a different size on the other one"
