John ,, you need to get a better JU-JU doll , or read the instructions  

Cheers Rob

Bollox, just read the instructions and I need to dip the pins in the blood of a virgin first.
Well that shags the whole setup up then don't it, chances of spotting a virgin round here are the same as Lord Lucan winning the grand national on Shergar.

Looks like you are safe for the next pour, mutter, bollox, rhubarb and double bollox.

John s.

tis a good job you cant fined a virgin in it ,,,,,,,, you better fined one for the next pore ,,,,,,,, its sorted 

Cheers Rob

Hi Lads

I finally got to fire up the furnace this after noon , added a couple of risers to the mould ,

the riser was full , this shot show how much the riser fed the mould

Looking good ,no sign of any shrinkage , just started to dig it out the sand

Removed from the sand , with the core intact , as i dont want the core sand to mix with the ,casting sand



The core sand removed and some of the flash


Still have to cut the gates off and a bit of a clean up of the parting lines , quite pleased with the core wash for a home brew mix
A few shots of the gating




Cheers Rob

Edit :  Oh how my arms hurt ,, Just to give you an idea of the weight of each moulding box , imagine 4 , 2 ft x 1 1/2 ft  flag stones flat in a stack , then having to lift ,turn , and then reposition them all in one go together  , that how heavy each flask is ,, and having to do it a few times cos some lump of sand had fallen out of the mould that should not have

Knew you would do it!

Now what the heck are risers??

Eric

[Divided he ad]

Now that looks good Rob    Top marks for Percy verance ( you know the guy?    )

Oh how my arms hurt

But think of the underlying benefits..... it won't be long before this feels easy and the slightly smaller ones are no trouble at all.... It's amazing how fast the body re-adjusts muscles to do the tasks demanded of it 




 

Now what the heck are risers??

  I was kinda thinking the same thing.... Like an expansion tank?
Feeding during shrinkage? as the outside of the casting sets the risers keep the inside pressurised/fed so it doesn't collapse??  (or am I just inventing stuff in my hectic tired head again?  )

Also, is flash the thin overspill that is cut away where it has seeped into the gap between the moulds?





Looking forward to seeing the rest of this take shape too

Woo-Hoo!     It looks good! 

I just knew third time would be a charm.  Good thing John lives in a loose town so he can't put the
hoo-doo on you again. 

Thanks very much for answering all my questions, Rob.  I'm gettin' a casting edgamakashun here.
The price is right, and the course is first rate!

I knew you could do it..... Eventually!

Hi Rob

I had every confidence that you would crack it ...    

Ignore the comments off-stage from (S)Nottingham. (Hawk, Spit, P'toing).

Try a search on Snotingaham      


Success is not final. Failure is not fatal. It is the courage to continue that counts.


Winston S. Churchill said that, ... err, ..not to me personally, ... and I think it was while he was still alive ..

I can hear the engine running ...

I have been following along with this and have got quite an education in the art of casting and mold making. You have had a couple of goes at the casting bit but every try was better and you look to have it beat now. The finished casting sure looks a treat. I am looking forward to watching this come to life under your care with the mill and other pieces of equipment. I'll be watching for future episodes. 

For anyone that didn't look up Snotingaham, here is a quote from a google find.

"In 1086 the Normans assumed control: they dropped the ‘s’ from Snotengaham, and preserved Sherwood Forest to provide hunting for Norman kings."

Hi
Rob we had some cylinder heads to fly cut at work there were no suitable mounting points so we set them on 4 big blobs of dry wall adhesive (plaster of parris type stuff) this worked a treat nice gentle cuts

nah .... he could sit it in a basic shuttered pour of plaster of paris - but there was a clue in one of Rob's earlier posts .... instead of using plaster of paris, because Rob's into hot casting (but he want's something of lower melting point than the Ali) he'll just pot round the engine with chocolate, with a biscuit base, and some peanuts for aggregate?

Funny you should ask.   I was working a project just this weekend on a lower mount for the quill on my mill, to mount the igauging indicator I just bought.  Nothing fancy like what you have been doing, but it was a first attempt with split pattern.  It's not totally done, but it's turning out OK.

 A couple of pictures:







Hey! It even fits! 

[Rob.Wilson]

Hi Al 

Great job ,the casting came out very  nice and clean ,, sure dose save allot of material making a casting  .

Hope to see more of your casting 

Regards Rob
