I printed some valve caps on my 3D printer.
I would post a photo, but it may get me put on the naughty step, however @Tangledfeet has seen the images via a different channel

Yup, they probably would!

To @The_Yellow_Ardvark , what are those pieces of wood that look like a very long and very flat U? They appear in almost every picture. Do I need a pair?

I do have some PG friendly ones planned, but they'll be a job for when I can next be bothered to play with Blender.

They are a set of felt clamps.

Went in the woods with a friend and his father for asparagus
We found 650 gr togheter
His father 1150 alone

They are a set of felt clamps.

So not "a long felt want"

What do you cast with brass?

Its a chinese one with a 50v 50a power supply from ebay. The original connections are rubbish but once I have that fixed I will do a proper test. The big 135mm dia 5m coil is going to be too long but it is the right size for my SiC/graphite crucible. Others have shown them heating cruicibles but I am not expecting that to work. This really needs an ossiloscope for tuning it.
I have some brass and copper scrap I will try but I doubt it will heat, and 30kg of aluminium to melt.

Anything up to about 6 ounces in a small graphite crucible . Hoping to cast some useable ceramic crucibles in the near future when the final materials arrive from the sellers any day now . Have made several wax forms ( green carving wax ) in silicone moulds but the wax was too hot @ 300 oC and melted the silicone giving me a blob of silicone & wax . Purchased some lower temp wax from China ( blue 180 oC melting ) & some liquid silicone with a catalyst which is supposed to take up to 250 oC before it too melts , it's also supposedly in the post & expected in tomorrow .

What's the reason for the couplings instead of the pipes being crimped on to solid brass terminals .... I have a nice octagonal long arm hexagonal terminal crimping tool that can handle 4 mm to 16 mm tube crimps think I may be able to use that instead if I'm going to make an induction furnace.
When I get to melting my alu & die cast zinc scrap I'll be using a big 80 mm Bullfinch tar burner lance on full bore . Heating the aluminium on some expanded pressed steel sheet so as the it melts it will fall through into a water filled wooden box like rain drops & stay in that shape ..... nice & clean when cold ( hopefully ) .

Then I'll be using my small forge ( or home melter made from a 24 in high ex butane cylinder of reinforced furnace concrete & a home made welded up steel melting pot to turn them back to liquid Alu for casting . If that does not work I've plenty of Plaster of Paris to do a pint sized slip cast of fine porcelain slip to make crucibles and get my wife's pottery making friend to fire them up in her big electric kiln

More workshop organisation at work, trying to get stuff off the floor, nothing ground breaking here, but it all helps.View attachment 273050View attachment 273051

Workshop Organisation 2

Found myself sat in an electrical cupboard with this delight.

I often find myself digging through thé drawers, so after 6 odd years i pulled off the protective plastic and 5 minutes and a few stupid spelling mistakes.

Nothing amazing, but made me happy, I'm easily pleased.

Perhaps I am missing something but I think I need to clarify that the plate bolted to the underside of the slab is for visual \ cosmetic purposes only and is not intended to nor will it stop any water. You need to stop the rainwater from coming down the chimney with a cowl - something similar to the one pictured below.

I did realise that but I was hoping to avoid nipping up to the chimney until the summer. At 76 I need to pick the perfect day for that kind of fun. I wanted to send the grandson up inside but when I measured him he was just that bit too large. Thanks again for you interest.

I have spinal issues a bust shoulder and an artificial knee joint so I paid my 40yrs younger associate a bottle of brandy , a decent roast beef & yorkshire meal to cap my chimney off .
Letting him use my ladders & supplied sand & cement etc. , mixer and disc cutter to cut two slabs to size , bed in some "U" shaped annealed copper venting tubes and cap off our chimney ...... have to smile at my cleverness when it's really frosty weather , as the humid air in the fully vented column condenses as it passes up the chimney and drips back down the salt glazed flue on to the top of our electric looking like log burner fire top

I give it five weeks before they come off .

Ha, ha, we'll see.

Couplings because then easy swap and to store. 3 and perhaps more different sized coils for different jobs.

The dripping molten alu into water sounds a really good solution to collecting usable scrap - doesn't it frighten you though?

Ooh someone's too posh for masking tape and a sharpie.

Ooh someone's too posh for masking tape and a sharpie.

That's always been my go to set up, but hey, what's not to like?

Kind of looks posh / professional ?

I just borrowed it from work for the evening, no way I'm peeling off all that masking tape...

But does look smart.

whole drawer shot, failed on the first photo.

I have a similar indexing system using Chinese takeaway food containers

No, not concerned at all as the grid will be at least 30 inches higher than the couple of inches of water in the top cut off & removed ex gas cylinder . So I won't get splashed or even damp from hot water or burnt by the molten aluminium ...

It's how they used to make lead shot in 90 foot tall towers , several tons at a time pouring molten lead through a round hole screen bucket , the length of fall to the water pit lent itself to a quality spherical lead ball forming at low cost . . Once cooled they were then graded for rollability , being roundish over a set of drop out tables then sized along two long heavy iron rods set off parallel to each other so the smallest stuff drops out first . some would go to shot gun cartridge makers & others to haberdashery concerns who made lead weighted rope/cord for dress hems & curtains . Some would go to angling concerns as split weights & they also went to various engineering establishment that wanted soft lead pellets to balance things or to set a slotted head screw thread in a small hole
