Was I dreaming, or did I see AB with a digital level indicator, a device I presume would do that the same job. From memory it was being used in a milling operation on top of the vice. About the size of a packet of fags. I'm sure it was this forum, but could be wrong.

You were either dreaming or dazed KJ. That device you saw was Pete F's . Refresh your memory by having a look at Pete's Hercus Surface Grinder post.

On the level? No doubt about your memory, thanks AB.

Works on the same principle as this, only with sophisticated attachments and more money.

Yep, Bob has it right. Around this pop-joint Bob is in control of the precision machining, while I handle the bodges. What I was actually doing Ken was to use a slightly modified el-cheapo vice to hold a lathe bit at the appropriate compound angle on my surface grinder. The digital protractor was being used to find the angles. While their resolution is 1/10th of a degree, I have no idea just how accurate they actually are in practice, but in this instance the rather flimsy looking fixture and bodgy method for finding the angles is perfectly acceptable as no real accuracy is required for grinding the tools anyway, and the whole thing works perfectly.
Anyway, I now return you to your regular viewing

More work
It's starting to take shape. I created a bit of a mess where the handle pocket changes angle. I used a 5mm slot drill in a ER16 chuck on a long 1/2" straight shank to clean up the transition point. There was a fair bit of flex in the long shank resulting in the cutter biting into the sides of the pocket. The mess is hidden by the handle so I can come to terms with it.

Bob what's the cutter you're using there? It looks like a shell mill, but sitting in an ER32 collet or similar???

Pete,
It's a 1 5/8" end mill mounted in a 1" ER40 collet.

Hi Bob,
You are making good progress, it's starting to look like a plane!
Nice work
Regards

AB,
Great machining so far, are you taking orders from GQ?
Is there a sales outlet in Melbourne for Presto tools?
Had a look at their web site, no clues there, sounds like they have had a colourful past.

I haven't been sleeping, I've been waiting for a ball nose end mill to arrive from the States. I thought that I would do a bit more work on the frog and mouth of the plane this afternoon.
My intention was to set the table at 45 degrees then tilt the cast iron base in the vise another 2 1/2 degrees. The Vertex vise didn't fill me with confidence in it's ability to accurately hold something at an angle since I couldn't belt the thing down onto a pair of parallels.
The table actually swings a few more degrees beyond 45 so I guessed where 47 1/2 was. I spent a bit of time clamping the base onto the table only to find I had to reposition two of the clamps to avoid the chuck.
I also found that climb mill cutting with a half inch end mill, 2 hp and a sturdy mill can still cause grief. It dug in and twisted the head out of alignment. Four M10 cap screws secure the head to it's mount.
I'm running out of room at the sides of the mouth with the cutters I've been using. I might have to tilt the table on the X axis and nibble away with a small ball end mill or even a burr on my Dremel.

AB,
Fancy setup, nice looking clamps, not to mention the cast iron machined block.
Nice to see the mill is set up in the middle of the living room, there's not a chip or scrap of cast iron dust to be seen.
