More 316 turning.

The grandsons desk now has simple extendable legs like this.
Attachment 398383

To hold the legs onto the frame I used the same 50mm SS M8 round head hex socket screws as those for the barrel nuts.
Initially I used plain SS M8 nuts and a SS washer as shown by the green arrow but decided they looked a bit ordinary compared to the barrel nuts so I turned up 8 round nuts with slotted heads from the same 20 mm rod as the barrel nuts.
Fair bit if work for 8 nuts but I reckon then look a lot better,.

Next problem was I did not allow enough hole clearance on the backside which has a stretcher between the legs.
Not a problem - just have two assemble in correct order and make sure the round nuts are slipped into place before the stretcher bots are tightened.
The slots are enough for fingers to hold then till the bolt and nut grab so there's no need for anything in teh slots to hold them

And a "just-cos" thing that turned up while turning the round slotted nuts.

Been very occupied with house renovations which includes a shed expansion. It has begun. floor will be finished by friday and the brickies will start about 10 days later.
The shed is currently 27 meters which is so cramped since i bought in the new machines. I have some stuck outside and will be most happy to get them into the shed. I am also making a storage area under the new patio to house stuff like the engine crane and other rarely used stuff which will free up some more space in the shed. Unfortunately the renos have a fair way to go so not much shedding for a while longer.
Stupid photo comes out upside down, its fine on my PC so not sure why

Don't worry OBM, it probably looks just fine to Barron J John. Good luck with your project, you certainly have something to look forward to.

Hi Mike,

Now I have to make 8 round SS nuts with Slotted heads for the adjustable height legs.

what was wrong with the simple mortice and tenon joint that have been used be eons...lol

It needs to be collapsible. I suppose I could have done the side frames that way but I like turning better than woodwork.

1) Found some old secateurs which are a good small size. Jammed/rusted up. Easy enough to disassemble and scrape rust out. The thin (cutting) blade was OK. Just needed some gentle panel beating (i.e tapping raised nicks down) and sharpening.

Interestingly, the thick (anvil?) blade wasn't flat near the leading edge (the one that is meant to mate closely with the thin blade). So, onto the surface grinder:

and about 12 thou later, a nice sharp tool. But, if you look closely at this photo:
IMG_2931.jpg
you will see I cracked the casting that the anvil blade locks into

I think that might be a case of TOOO MANY WEETIES FOR BREAKFAST.
You don't know your own strength.

It can be strange how that sort of thing can occur. Many years ago I acquired a Sidchrome ring spanner, from memory it was 1" / 15/16, and had been heated and bent by its previous owner for a particular job on a 71series Detroit Diesel engine. I had that spanner for years and can remember bouncing on the end of it while trying to undo trunnion bolts on a Cat D8, and using a 3' length of 2"pipe for some extra grunt to undo some bolt without any ill effects on the ring spanner. Then one cold frosty morning it just rolled off my bench and fell on the concrete floor, snapping in two. I could not believe my eyes!

This spanner won't break when dropped.
I printed it as a demonstration piece.
It's printed as one piece and then you have to break/cut through any fine plastic threads holding the movable pieces together.

It sat in a box for 6 months but recently found a sort of use for it and that is doing up the nuts on cheap plastic bodied pots.
There's something about using a smaller lighter weight tool to reduce the possibility of stripping a light weight thread.

Every time you’d go to an engineering show they’d be printing those useless spanners as a demo for 3D printing.
I can’t believe there is actually a use for them

It would have gone "Ring" tinkle though when it hit the floor though.

1) Bought some stainless tube from Edcon. The surface was rough. Too rough (it is going into a kitchen). ... but I don't have time to turn then all smooth in a lathe, so I cleaned them up on the linisher.
First, tried lightly sanding with a rod down the middle, but then realised I could fake centreless grinding?

The table is at 90°, but the tube nicely stuck in place, slowly spinning!


2) Was cutting some slits in 6mmx60mm steel strap. Carefully angle grinding, watching the line (and my fingers). Finished the cuts, then started welding smaller strap onto the edges. Then, looked down at my hi-vis shirt:
IMG_3138.jpg IMG_3137.jpg
Looks like there was a concentrated stream of sparks from the angle grinder, that the (polyester?) material didn't like?


3) An odd job. Some stainless steel stamped/cupped discs need shortening by about 5mm.
Made a wooden buck on the Hercus, and machined a little metal centre for the tailstock to push the discs into the buck. Then, with a little foam, push A into B, and use a parting tool to machine a ring off it:
IMG_3159.jpg IMG_3158.jpg
0.9mm thick stainless, so it chattered like crazy. Had to turn each one around and emery paper the cut edge.
The foam didn't last, each square did 1 or 2 discs. After 10 or 12 discs, I realised that forcing the tailstock in harder clamped the disc well enough to do it without the foam.


4) Someone gave me a broken drill press (Hare & Forbed BD-320something?). The cast iron motor pulley is trashed:
IMG_3162.jpg
It has been gyrating around on the motor shaft for years - held on only by a grub screw in the keyway slot. The top and bottom on the pulley hole are tapered out from the middle. So, bore it out on a lathe, and then machine a sleeve to fit into it:
IMG_3163.jpg IMG_3164.jpg IMG_3165.jpg IMG_3166.jpg

Then, the tricky parts. Pulley had a damaged M8 grubscrew in it, so drill that out with a 5mm, drill a hole on the other side for another grubscrew, and try to extract the bad one:
IMG_3169.jpgIMG_3170.jpg IMG_3172.jpgIMG_3174.jpg
(one of the few times an Ezy-Out has worked for me!)
Tap the other side M6, and drill a clearance hole in the sleeve:
IMG_3171.jpg IMG_3177.jpg

Now, press sleeve into pulley, and try to fit it:
IMG_3178.jpgIMG_3179.jpgIMG_3180.jpg
(that new M6 grub screw is a little long, and the end needs turning down to fit in the keyway slot)

There are still a few more things to fix.

A) The motor shaft is worn from the gyrating old pulley. Top has worn smaller. I thought I had bored the sleeve to compensate for that (one end is larger than the other), but I pressed it into the pulley the wrong way!!!
Which means the pulley fits on one way, but the belt steps are back to front.
Will try to press the sleeve out, and invert.

B) The intermediate pulley has dropped on its shaft:
IMG_3181.jpg
Will need to remove that, and repair the spacer, or whatever is missing.

Nigel I’ve had similar over the years so when I was working at ACU and they bought leather welding jackets and were throwing out the old leather blacksmiths aprons I purloined them for mates and myself.
I think I might still have a spare if you want it.

Watering the fruit/veg on the weekend, and the hose nozzle went ping:
IMG_3636.jpg

A sensible person would throw it away (maybe after rescuing the brass in it).
As we have already established, I am not sensible


Look through the scrap for a replacement. A cupboard drawer handle:
IMG_3637.jpg

Into the Hercus.
Drill 5mm (which wandered a lot), stepped shoulder:
IMG_3639.jpg

down to 8mm, then tap M6:
IMG_3640.jpg


and it works:

Not quite as smooth as the original, but at least 24% tougher!!!
