Stuff you have made today

[Maker]

I've had this articulated arm thing for a while, finally putting it to use. Bore the end out;

Machine a bit of brass to fit;

Glue it in place;


Done;


Nice big microscope mount, just needs fixing to the wall. Even says Olympus on it.

Repurposed some copper pipe as soft jaws. I was hoping it would reduce the ringing but it taps the same.

Didnt find time to turn as I was reminding myself how much I hate brush painting and fixing a bowed door frame.

snug fit

Made a spindle spanner/wrench quickly to see if I could get the chuck off the Triumph this aft. Not only did it fit great, not take long to make, but it also worked and the chuck is off, I don't think it's been off in at least 20 years, had to warm the nut to get it to move, then warm the backplate to get it to release off the taper.

Taper looks clean, key is fine and tight, the very back threads are a bit iffy on the nut, chuck side looks fine bah 20yl years of chips and rust in behind the spindle nose.

Clean it up and refit, might strip the 3 jaw as it's notchy and tight in spots.

Made a start on harvest 21.

Not all today but made a clearspan roof for a mates tractor shed between two existing buildings that are on the skew ..Back part will be profile sheets on a steel frame and the front will be timber/tiles to match existing. Joined two gurt beams I had in the yard, the rest is 100x50x4mm box and 50x50x4mm angle. Our brickie built the walls. fair match.

Roof sheets go on tomorrow and the chippie will be pitching the front part of roof.

Mick looks even more cheerful than ever - what on earth have you done to him?!

He looks like he's deep in thought, or trying to fart

Having met Mick a fair few times and shared a brew with him - he's definitely not deep in thought!

E/stop done, light's done, way cover widened and motor guard (to stop chips falling in it!).
Time to start making something before I fit the DRO .

 

[Seadog]

A beautiful job.

 

[Kram]

Turning the OD of plate and its starting to become round'ish. Im using the wrong insert, far too big for light cuts and they were getting too stringy. I decided I *need* a ccmt0602 lefty holder before I continue. None on amazon and didnt want a long wait from china or royal mail. I also wanted a decent size shank as it would have a reasonable stickout, this insert size are usually on 10mm or smaller shanks.

First idea was if I coated a scrap insert with release agent (we used to use boron nitride for hot sintering, no idea if it would work for this), I could braze a close fitting pocket around it and then remove. I dont have any BN, but Id like to try.

Next idea (not mine though) was to make the pocket from 3mm plate and braze it on. I liked this idea, but better with tig to preserve flatness under insert.

Shank was from a boring bar holder, plate was from an old doorbell.

The corner had a slight chamfer so I went to build it up. It helps to turn the gas on

Welds a bit ugly, but Im only going to grind enough for clearance.

Above is the tool I was using, one of the first projects I milled, took ages to do the pocket - a file and tig is quicker!

What size shank do you use? I've got a few ccmt tools in that size with 10 or 12mm shanks from my myford.

If you have the facility to braze, why not just braze the insert in place?

Brazing is a pain, it uses a reasonable amount of gas and only gives one edge then burns whatever coating is on the insert - this steel is sticky on uncoated inserts and gives a buildup on the edge. One of the few times that Ive seen value in the coatings, usually I dont care for them.

OD tools 12-16mm. I could have used the big 32mm lefty boring bar but still need to buy inserts, and not sure what the chips would be like on this.

 

[Munkul]

Why don't you use a negative insert for that job? The edges would hold up better.

 

[Kram]

An intermittent cut of 200mm round on a small chinese mini lathe like this, makes quite a bit of noise. Also negatives are generally bigger and need massive cuts for the chip breaker to work = stringy dangerous mess.

@Munkul what is your new vcmt16 inserts like for chip breaking at 0.4mm deep cuts? I might order some, or, a pack of the YB251 grade chinese ones.

 

[Munkul]

That's what I mean - you wouldn't need to worry about chip breaking on an intermittent cut, and once you're down to clean metal you can fly with the positive insert tool
Not that it matters, obviously whatever works, lol
