What did you do Today 2018

What a lucky 3-year-old !!

Nice job, Mick

MichaelG.

Today I repaired a broken compressor crank , brief description below .

Firstly , I removed the bearings , and trued up the crank in my Myford ML7 lathe using a dti and held one end in my 3 jaw chuck and used a fixed steady on the other end , I could then face up the crank and drill and bore a hole to locate the spigot on the new piece I make .

I knurled the spigot and pressed it in the crank , I also pinned the spigot , more pics in my album .

Is there going to be a small prize for the last "what did I " of 2018 or the first of 2019?

Perhaps you might get an official Round Tuit?

First post will go to me when I create the thread

Seriously, why does it need a new 2019 thread?

It could just be 'what did you do today'

I wonder what caused the shaft to break?

No indication of diameters involved from the pictures but I'm assuming its 20-25mm or so and that would take a lot of force to break. If the compressor is belt driven and there was a latent defect in the metal then constant bending fatigue would eventually do for it.

I presume you are going to run with a lot less belt tension now (unless its actually driven by a shaft coupling or another method that does not apply radial load).

It’s not my compressor , I was asked if I could repair it , the diameter is 7/8ths and unfortunately the compressor was dropped when it was being unloaded , it was a nice clean break and on investigation the casting looked to be of good quality .

Treated myself to some new clamps!

These are the first set of Kant Twist clamps I've had. Just like the look of them!

It used to be one continuous thread and got ridiculously long. A new one each year brings some sanity to searching for a thing you remembered was posted a few months ago that turns out to be 3 years ago. Some other forums haven't broken their equivalent thread and are a bit of a mess with lots of threads grumbling about it.

Made a missing Dove tail cover for my George Alexander Master Toolmaker dividing head.

Happy New Year!!

Made a new coolant tank to replace the miserable plastic 'generic' tank that had perished cracked and leaked all over the floor for far to long..

Pump mounting cracked right out of the tank!

Corner cracked and leaked out...

Ali Fabricated tank.

Becoming good at TIG welding Aluminium..

I dug this out of my 'Scrap-box/store' - ends up a long post - where is the best place in the forum to post the story???

Joe

Got new HTD pulleys fitted to SC3 to replace non standard belt drive as fitted. All works fine, a little more noise than original belt.

As usual , on Saterday morning I headed off to the local road side market. On one stall I thought I spotted a Tool Post Grinder, it wasn't, it was an Emco Unimat Modell SL. Lathe, drill press, scroll saw, and some sort of mini planer for wood. Also a flexible drive shaft. There are two lengths of bed bars. I'll set it up, then start asking questions as I find bits I can't work out. Basic turning should be no problem. I didn't try knocking the price down, but I though $NZ 150 not too bad as the machine has had very little use, in fact some of the bits have not been used. Just got to clear a bit of bench space now.

Possibly the understatement of the week, Ian

Well done, Sir

MichaelG.

Bought a pair of ER25 collet blocks a while ago. As useful as they are ER collets don't hold short bits very well. So decided to make a pair of hex and square for my 3C collets. Just used some bit of steel I happened to have in a suitable size.

Collets are drawn in by a threaded ring.

Also made a 3C step collet out of brass to use for holding some cylinder covers I am making. Made from two pieces of brass brazed together (to save on waste).

Today I got fed up with cleaning the Y-axis lead-screw on my Boxford, this is exposed as I have the taper turning attachment, although I don't often fit it.

I did a quick model in Fusion 360

Printed it and hey presto, it should keep the screw clean.

This is the first time I have designed & printed something, yes I could have made it out of metal but it made a good learning exercise. Now to make and print tools to clear the t-slots in the Bridgeport, I have no idea how long they will last, but another learning exercise!

Baldric

Not nearly as impressive as Barry's but whilst sorting out some tooling found a 4.5 mm boring bar that I'd bought some time ago, but no holder for it, so a bit of stock sq. ally, bit of time on lathe, e voila... one mini boring bar holder...

I'm jealous of you lot! I'm 'between workshops', so most of my equipment is inaccessible. This morning, I sprayed (back-pack) 100 litres of glyphosate, but was stopped by the breeze getting up. Job only half-done... This afternoon, I took pity (again...) on neighbour and chainsawed up the big lumps of the poplars recently felled on his land. Two-foot diameter trunks, but easy going, for a big saw and a beer-refuelled old man: there was just rather a lot of it (I mean the timber, not the beer). One day is much like another, really...
