In my mind, that's pretty much what I'm making, with the added bonus of being able to set out precisely if required.

Turn the work 45 degrees - put it on its side.

Re-clamping was certainly an option, I need an excuse to make LP ones. :D

Will I have to re-temper after?

I don't own any gauge blocks yet!

Although I suppose the larger the sine plate, the less accurate the stack needs to be?

Perhaps at this size the stack could even be machinable?

Actually the bottom of the 'v's are quite blunt:

That cutter with those inserts was just a quickly Googled example.

I'm sure you can pick-up sharper cutters.

As some might already know, my facemill is currently out of service, awaiting new inserts.

So I thought I'd break out the virgin flycutter.

This is my first ever attempt - be kind!

So I ground what I thought would be a good shape into some 8mm HSS square bar:

There is side and bottom clearance and a chip break breaker with a small rake angle.

The finish was, well, not great:

You can feel every line with your fingernail. Not subtle either.

I tried messing around with speeds (180RPM, 280RPM) & feeds and DOC (0.1mm, 0.3mm, 0.50mm, 0.75mm).

Not great.

Looked okay whilst cutting though:

Cutting deeper shook the house:

Another detour. This time from [Project 4] Sine plate.

I need (would like!) some low profile table clamps to be able to resurface stock too large to be held in a vice.

Taking inspiration from Harold Hall and Quinn Dunki, I plan to make something like this:

Detour: [Project 4] Sine plate

This, like many of my projects I suspect, is a spin-off from [Project 3] Dickson T1 Tool Holder

This option was chosen because it seems the most sustainable i.e. it will be used on other subsequent projects.

I have, in my possession 2 x 32mm thick steel plates taken my old welding table. They're 90kg each!

I took a section from one of them using a 4" angle grinder!

It's around 400mm x 250mm (and weighs 20kg).

The first task will be to square it up.

However, a couple of issues are impeding;

• It recently transpired that my facemill has shoddy inserts
  • Currently waiting on new ones from Arc
• I am lacking low-profile table clamps
  • [Project 5] I think! Sheesh, how far does the rabbit hole go?

I did see both of those posts, thank you.

Not overly keen on using a countersink for this.

Seen some 45 degree side cutters and was considering something like THIS.

I think I'm going to go for a sine plate, 'cos why not (and I think I'll get use out of it beyond this project).

Ah yes, I see. Thanks for getting back to me. I'll add the 1:1 technique to my toolbox.

Ah, I thought 'block' was the holding method (like 'v' block). Thanks for clarifying.

Yes, that's what I'm after. How did you mount it at 45 degrees?

Apologies Ken, but what is 'block'?

Don't suppose you took a picture?

What was your method for cutting the 'v's?

Sorry David, I'm not sure I understand.

NB: This is the smaller T0 size holder, right?

I'll go beat it a few more times with a rubber mallet.

It was dialed in until I bolted the head down.

Yes, that is the plan. I can squeeze 4 in if I do it this way.

However, I'd really like to be able to cut the 45 degree 'v' slots on the X, then I could cut more at a time.

Still haven't figured out a way to do that yet.

Just to clarify, my original question was:

What *should* a Warco Super Major Milling Machine be able to accomplish?

... because that's the machine I have. I just want to know what it can reasonably do.

I'm not in the market for a newer, larger machine.

I fear this thread may get off topic pretty quickly.

If you'd like to follow progress or get involved in further discussions, I started a thread over at:

[Project 3] Dickson T1 Tool Holder

Tramming the head back in to 0° (vertical):

How does 0.1mm over 480mm sound?

So 1mm over 4800mm (4.8m)?
