Stuff you have made today

Are you wise?

He went for a run, make your own mind up.

 

[Kram]

Am I on the wrong forum?!? Who said anything about being wise
I did enjoy the runs, or atleast the second half, the first was hard and should have, if I were wise, had beers before I went.

Having fun out in the sun. That's a 24B sprocket by the way

Another custom socket, this one's a face plate...


The neatest section of weld;



I only tested it on the impact, screwed it to the bench and sheared off the screws. It'll actually be used with a breaker bar. It's made to be bolted to the flywheel of seized outboard engines to rock them back and fourth and free them up. The slots were done on a small waterjet, I just machined it smooth, made the socket and welded it up.

A gate hook for Hay castle entrance gates,it’s had some big funding in the recent past,set to become a major tourist venue,complete with restaurant .
Biggest one I’ve made.

Is it Sunday already?
You might remember that cool thing I was making

If you are doing it for fun or scrap value it looks good.

If for machining you need to heat your moulds, then top up. It stops a lot of the shrinkage you can see.

Did that for the rest, now need more scrap ha.

Only need to make 44od 35mm long rollers, mold is 80mm long so should be able to get 2 out of each slug

It might stop what you can see but it does not make better quality. Topping up will trap a layer of oxide film.
You dont want the mold hot, just be sure it is dry and let it cool off to ambient before pouring.

Keep the top surface hot after pouring to allow for shrinkage. If you dont, the top freezes first and you get void bubbles in the hottest area, the centre and throughout.

Sand molds are the better way, with a steel peice to chilll the thick sections.

Nice

No, not here anyway

no experience with casting here... but I always thought mould as hot as possible was the best bet? and let the pour cool as slowly as possible?

maybe stick a lid on it after the pour to keep the heat in?

Table top ring toss game...

I have a portasol gas iron - i would buy insert heaters like that no problem if i w]could get them. no threads involved.

I've tried that at the beginning, thinking the same and had bad results, then I did some reading up. For thick sections you should cast against a cold chill. Gives smaller grain and no porosity or shrinkage.
When solid, heat treatable alloys should be water quenched then heat treated for best results.


Today, sun dried the rest of my sand and took only minutes to sieve 14kg.
Im going to get a finer sieve before I mix into greensand then dry again.

and here's me watching all those drop it in water / drop it on ice people thinking they're making a hash of it trying to rush things for YouTube points :-p


every day is a learning day :-)

Explains it well, most of his videos are worth watching.

Dug a hole today and had a play with my die filer. Just a small bracket to weld on the top of a new scaffold pole as a hanger for a pulley wheel. Its part of the support for my idea of raising up an outdoor washing line in the back garden.

Started turning the first one cast, so far minimal porosity and cuts beautifully.
