Stuff you have made today

For those that remember my gate build and asked “why are the gates so close to the garage, well I made space this weekend by removing the old garage. Need to do the fence to finish it off
Also finished the side door on my garage.

 

[Kram]

Started on the small one, it turns lovely. OD and face turned, now to start on the bore.

It was going well until I found a dirty great hard ring. Tons of noise and chatter, got through it, but thrown the face and OD well out. Having some lunch before I clock again and finish off the bore.

 

[Milkybars]

Not something I have tried but on a recent video I watched they withdrew the tool outwards on the cut ?
It may help !

 

[Pete.]

Going by the look of the swarf that's a decent bit of steel, you might have cooked the surface and hardened it. Reduce the tool overhang turn the speed down and if your lathe can handle it pile in on the feed rate. Also hit it with some coolant spray when it gets to that hard spot. Hopefully it will take it out in a couple of passes.

 

[Maker]

It does look like the bar is sticking out further than it needs.

 

[Brad93]

Looking at your swarf you're tickling it. You need to take a good 1.0mm depth of cut with CNMG boring bars on tough steels, you want your chips taking the heat out of the part.

 

[Kram]

Its only chucked up by some 3mm wall tube with a bead of stick, in a chuck I dont really trust. It has moved so deeper cuts are not the answer, going to pull it and check the weld. If it were gripped in the Bison by the OD I would agree with you.
Doubt Ive work hardened it, it was about 10mm deep, its not getting that hot.

Yes the 20mm bar only fits that holder where its been adjusted with grinder.. I will swap the new holder. The 32mm bar fits but I am resisting the chance to burn up non ferrous inserts, I need to buy some.

Im told the plate is s355 grade.

 

[Pete.]

S355 is high strength structural steel but stil low carbon. Normal strength is S275.

You say it's 10mm deep but it might be that you're re-hardening it every pass. Of course you could be perfectly right it might have a higher-carbon layer rolled into the plate.

After some friends saw what I did with one in the past. They wanted one.
So I had spares.
One is going to Scotland and one to Israel.
I wonder which one will get there first.

The chains were de-greased with engine cleaner and then "Meths."

The brazed on.

Where's the light bulb?

Could be, but I dont think I were putting much heat in. It was exactly like the weld bead. The surface did not look welded at that diameter so who knows.

Gripped on the ID much better, was not moving about.

Bore done. The face is a little rough so I'll give another face cut tomorrow. Dti doesnt see the hard bits so I was going to leave it in.

Made a little handle to speed up lathe tool changes till I get a qctp sorted. Welded a studding connector nut to an old knackered 1/2" drive socket as the studs are 1/2" Square. Plastic handle was off one of them rubbish hand winches.

 

[Kram]

From last night, drilling..

If I got a bigger pan would I just put more in?

 

[Chillitt]

I made a hole.. I say today, Ive been picking away at it over the last week or so, but today I can walk through it. The kettle is now a third of the distance away and I can see the telly while making a brew. Also I can hear if anyone comes to the door now, which is nice.

 

[Maker]

Made a couple of pulleys, trepanned the big one as it's such an awful material, the small one and the blue spacers are Delrin and an absolute dream to machine.

 

[Kram]

More backplate. The spindle has clearance holes for m10 so it seems silly to use m8, but I dont have any suitable studs or nuts. First time using the Zoro spiral point tap and it is good! Im going to order some more spiral taps, they work far better than taper/second/bottom sets.

This inserts too big and wont break chips on a fine cut. Dont have a LH holder for the small ones.

Small ones break chips ok..

A bit more, got a bit confused on speeds as the pulley was slipping, Ive moved it over to the big pulley then had it far too slow. Bumped the speed back up to 700 and its much nicer.
Smashed one of these tiny inserts being greedy with depth and feed

Don't forget to link if you find some amazon bargain spiral flutes!

 

[Kram]

Mostly made food stuff today. We bought a steam juicer (a common finnish household item). This year we'll have a decent harvest of black currants, maybe the red currants might be saved too if we get rain soon.

Anyway my first try was a pure experiment, I had heard people make cordial using black currant leaves and lemons. I used limes since I had no lemons. Also some sugar.

I got about 500ml of a orange looking concentrate. Since it was an experiment I used a suitable container. I also cooked some black currant jello which goes great with meat like pork chop, it's better to make jello earlier since the berries are higher in pectin then and cordial later in august when the berries give more juice.

Turned out quite nice, odd, but nice, refreshing! I think you can also make tea from the leaves.

That is a good collection of tea strainers

Where did I put my m10 transfer screws?...
