What did you do Today 2018

[Harry WilkesParticipant @harrywilkes58467]

Finding that with arteritis in my left wrist and numb fingers that pressing the start button getting difficult so I move the stop/start unit it's now a lot better to use

[Philip RoweParticipant @philiprowe13116]

I've had one of these table clamps on my drilling table for some years now and a very useful feature it is for securing jobs whilst drilling.

Sometimes the arm is too short to reach the job that requires holding, so I bought the next size up which has a longer arm. Unfortunately this one is secured to the table with a 12mm stud and the slots in the drill table are only 3/8", nevermind I think I'll make a smaller stud to suit. After more closely examining the way the stud is attached to the clamp assembly I concluded it was a lot easier to cut the stud off and make a new sub base with a smaller stud screwed into it. This is the result of an afternoon's work delving in the scrap boxes, I know it will never win any prizes but it now does what I want and to my mind that's all that matters in this instance.

By the way if anyone is wondering what the ropes are at the back of the table, they are part of a crude and simple counterbalance to offset the weight of the table when raising and lowering it.

I ordered a Prusa I3 MK3 3D printer at end of October. It turned up early November, but left it to yesterday and today to build when I knew I would have some free time.

Had little unwanted help as you can see.

First two printed items shown. Took couple of goes to get the printhead height correct to get the PLA to stick to bed.

I think they look reasonable. The first go at Benchy did not stick, did one layer then came loose.

Any suggestions for change, I just used the built in defaults. I know Neil is specialist in all this, perhaps I should buy his book.

[Neil WyattModerator @neilwyatt]

That benchy is pretty good – only minor defects on some corners.

I would just go ahead and print some objects and only worry about changes when you find prints not coming out as you expect.

[Jeff DaymanParticipant @jeffdayman43397]

I dunno about changes being needed Colin, that 3D printed cat looks REALLY realistic! ……oh wait……

Just kidding. the boat and sign are a start. Just keep practicing. There are lots of stick-improvement tricks depending on the bed type you have. glue stick, PVA glue, two sided tape, etc. I defer to Neil and others on best technique for your machine. Generally the larger the area of the first layer the better it will stick. Rafts and rims can be used to increase stick area. Speed of nozzle and feedrate of filament can have big effects on adhesion to bed and build quality too.

Merry Christmas to all.

In between trying to get the Chester mill motor off I have been making up a backsplash guard for the Myford Super 7.

Needs a bit more work to route the DRO cables and provide safe power to the DRO but basically finished it today. Fitted the DRO scales about 12 months ago and this is the first time I have powered them on. The display came of the Myford 7 I recently sold.

I need to fit the DRO modification to put the magnetic scale under the cross-slide but need the mill to do this or get my mate to do it on his Hauser jig borer.

Colin

That is impressively attractive. Congrats.

Not today, but 4 days back … finished this little racer to go with the 3-year-old grandkid's little garage set. It's titanium, brass and delrin, 22mm track by 67 long.

[Michael GilliganParticipant @michaelgilligan61133]

What a lucky 3-year-old !!

Nice job, Mick

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?

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.

Pump mounting cracked right out of the tank!

Corner cracked and leaked out…

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.

[Ian S CParticipant @iansc]

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.

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!
