Great photo Bazyle

Strangely enough, I spent yesterday afternoon trying to get the grey matter around all this.

I watched two videos;

1/ Toms techniques (screwcutting n°4)

2/ mrpete222 screwcutting.

After this I went out to the workshop and cut my first recognisable thread

Would recommend watching these

All the best

Thanks Bazyle, for putting up the photo. That's a real help, seeing them together like that.

The VMC actually has more headroom than my Becker which, until now has not presented a problem.

On the other hand, the throat is smaller. I can see issues arising there.

I agree completely about not lowering the quill for milling work; however, I don't really see a problem of rigidity in moving the head or the table. In view that both move on the column, I would imagine it amounts to the same thing.

Unless, as usual, I've missed something obvious ?

And, after all that, I can have the VMC with it's DRO and one power feed, for the price of the Super without a DRO.

All the best,

Daniel

. . . . and a decent tape measure

It's trajectory was erratic, to say the least, due, mainly, to it's complete ommission of a nose cone

However, it's "fuel" did always get it over roof height, after which they were tucked under the rather generous eave.

As long as they didn't move, they were reasonably safe

All the best,

Daniel

This thread thread certainly has more than 65% engagement

More basic and very little precision,

I made this bottle launcher for the children, a little while ago

Not quite ready for a moon trip yet . . .

An after note for Rod J,

Instead of going to work this morning, which I should have done, I went to the workshop and test drilled a piece of steel plate. The drill bit claimed to be a 6.5mm, from what I maintain to be a reputable supplier.

Lo . . . The hole was indeed oval (no joke), varying from 6.4 to 6.49 mm !!

BUT . . . . It wasn't oversize !

Hence my trip down to the supplier to source some more tap specific drills.

Now I'm viewing my digital vernier with some suspicion

Best,

Daniel

Mark,

Can't wait.

Just looking for a thread to do, now . . .

Sorry,

For M8 ; drill 6.8 !

Hello,

Okay - you all win

Have been to my supplier today and invested in a load of specific tap sized drill bits.

Having said that, I opted to follow the formula ((dia - pitch) + 0.1), to give a degree of clearance.

If we simply subtract pitch from diameter we will have 100% engagement, which, apparently, is to be avoided.

Unless I've missed something.

Mind you, now I've entered the murky world of increments smaller than a mm.

Best,

Daniel

Yes Rod,

I would be mightily surprised if one of my 6.5 mm drills came out anywhere near it's actual size.

Enter my el cheapo drill press into the equation and I will probably have an oval hole, anything between 6.7 & 7 mm. Give or take a tad.

After that, as Thor suggests, I usually go the serial tapping route, which is also quite forgiving.

It all depends, as usual, on what degree of precision is actually required for a given situation.

M8 is a rather meaty lump, after all

All the best,

Daniel

Hi Iain,

For all practical purposes, I would drill 6.5 or 7.0mm for tapping M8.

Unless the project demands any higher precision.

The sound advice here, is to tap carefully and rewind every quarter turn, to clear the chips,

you can always feel if the tap is straining unnaturally.

All the best,

Daniel

Thank's Vic,

However, the local community has been informed that my next move will be to the cemetery, and some will need to come and help carry out my box.

Once done with that, they can start on the workshop and the general mess outside.

They are, however, welcome to borrow my digger to dig the pit (not hole).

All the best, Daniel

Afterthought - - -

Just to allay any feelings that I'm favouring Warco, I must add that I have also purchased from ARC€urotrade, and have also received the same irreproachable service.

All the best,

Daniel

Hello Martin,

Welcome.

Being unable to get enough of engineering is quite understandable, but I don't think there's any treatment for it. The only thing to be done, is to hang around with people that will only encourage you, and possibly make it even worse.

All the best,

Daniel
