Morris is a better machinest than I'll ever be!

NB: This is the test piece (not full size).

Whose crazy idea was this:

Let's see how this goes:

Sounds like I might be able to squeeze it in the Y - then I don't even need the vice.

It will mean hand feeding though. Old skool.

Can't hold it in a vice in the correct orientation. It's too large.

Ah yes, I see what you mean now. Will do. Thanks for the tip.

Wow! What a setup.

I don't think the cross-traverse is long enough to use the tilting head, which is why I passed on that idea.

What do you mean by the last sentence? What long cutting edge did I pay for?

Don't worry John, that setup was just an example of how I need the work oriented.

I have been looking at those Duncan. Is that the canonical answer?

I'm currently attempting (with varying degrees of success) to replicate my T1 Dickson tool holder.

The next step is to mill 4 'v' slots (see the image below).

Looks like you can buy insert tool holders which cut 'v' slots at 90 degrees, which would suffice if I mounted the work end-up. However I'd like to avoid buying tools I'd only use once or twice.

I'd it we're just one tool holder I'd be happy to just shove it on the vice BUT the goal is to mill say 4 at a time from one piece of stock before chopping them up.

The current plan (unless convinced otherwise) is to hold the work at 45 degrees and use an endmill to make the cut.

How would *you* hold such a piece?

Sounds reasonable.

I'll get an order in today (and you can claim your commission).

Yes, of course. I know ARC's service is good, but getting new inserts same-day might be pushing it.

Well it's a relief to know that there might not be something wrong with the gears after all.

I did watch your videos, and I do plan on getting some new inserts.

Ah, I didn't think it mattered when facemilling. I'll try again from the otherside later, see if anything improves.

Thanks Martin.

The part is actually half that (70mm), so I guess my feed is way too low.

I tried raising it and it just became louder and louder.

Do you think after a certain point, the noise will start to reduce?

Sounds like you are viewing the pre-view. You have to click on the video to play it.

The next speed down is 280.

Grabbed a new, never been used before cutter (12mm 4 flute) this evening to clean up the mess.

Made sure to deburr the collet, put the cutter in properly into the holder and had at it.

Pretty happy with it in general (cuts are on the flanks of the slot - not a lot I can do about the bottom).

Spent some time on the mill this evening.

Firstly, I've put it on some interlocking foam matting, which has helped a lot.

However the over-all noise reduction has highlighted what I think might be a bigger problem.

Have a listen to the video below. The knocking coming from the gearbox is quite disconcerting.

I just bought one of their roughers - arrived today.

Might give it a spin tonight (with my newly de-burred collet set!) and report back.

This is what the inserts look like:

Not checked it for run-out, but the loud noise and vibrating happens with different cutters.

[Although, it has also just transpired that I have not been using my collet chuck properly!]

I'll do that Jason, thanks.

By push it, I purely mean DOC.

I don't have 2500RPM to play with. My machine tops out at 1600RPM.

Thank you guys.

I think I'm going to try rubber and to improve my technique in the first instance, then bolt it if all else fails.

Not anymore I'm afraid. That's a pre-lathe photo. The workshop is now quite full.

That stand is not made from thin sheet metal. It weighs more than I do.

Oh my goodness. Talk about a case of you don't know what you don't know!

• A 10-11mm collet was used
• The collet was not properly inserted/clicked properly into place (at least not intentionally!)
• The collet needed de-burring

Right, what else do I need to know - tell me everything!
