Hi Rob,

Not sure it is a good idea posting photos of my work in your threads. The casual oberver might think its from you, and that you have lost your touch.   Your reputation is at stake :)

People already suspect you have issues milling out square...



I don't mean to highjack your cupola thread, but when I machined my two motor castings, I drilled through the hinge axis with a long (~200mm long 6mm drill). Even with center drilling, I ended up with the axis alittle squewed off. You can see in the tensioning widget, that things didn't line up very well.

How would you have gone about that?

No worries , the cupola build has stalled for now due to other jobs  :proj:

I would have marked each lug out and drilled them individually ,from either side .

Thanks. I was trying to avoid that, guess it would have been the better of two unattractive options.

Good to see that someone is going to build a cupola. I have had years of experence in running one (9" dia). they can be very temperamental furnace to run so If you need help I can help.

It  has been raining here for 3 days but there was enough of a pause late today for me to cut up some 1/2" rebar and make up 2 botting irons and 2 tapping bars.

Better hurry Rob or I'll be the first to watch slag dripping out of my cupola into a pouring ladle! 

Puttin on the pressure, uhhuh, uhuh :headbang:
I love it when a Plan B comes together!

Ah, well Rob, I've got the drop door to do, the lid to line, lid lift and swivel mechanism, pouring shank, ladle, pig molds to weld, as well as make up some iron sand. So false bravado, here!  :lol:

Here we go  :)

After spending most of the weekend sorting out my workshops , had to take advantage of the good weather , I managed to drag  the furnace into the fab shop , it was a bit of a fight , big spiders and the ivy had grown over it  :palm:

First job was to remove the centre form .

before.


After ,


then a bit work to the stand ,I noticed this had a fare bit of spring in the legs when I was dragging it into the shop and the corners of the box section were also digging into the flags .
So some tubing was added to brace the legs , nice a stiff now . Some 4 inch bar was sliced up to make feet .I rounded the edge so they would slide easier.




these were then welded to the bottom of the legs .


still a bit work to do to the stand .




I better move my arse as Steve has had fire in his furnace  :D

Rob

Woohoo!

That is one impressive cupola.  :bow: :bow: :thumbup:

Mine did come along a little faster.

Just like a fire in a dustbin is faster to prepare for than constructing a convection oven for a pastry chef.

Any time you want to trade, Rob, just let me know!

Thanks Lads  :beer:

Only had an hour in the shop tonight so I decided to make the shoot ,were hopefully molten iron will flow from .

So I grabbed an off cut of 100mm box .


Set it at an angle I was happy with and marked both sides with chalk .



A couple of minutes with an angle grinder .



so I now had a shoot shape .



I decided to bend out the sides using a 2ft adjustable.

 

Once I was happy with the angle , mark one eye ball .

 

I needed to bend the other side the same , the original measurement between the walls was 90mm

 

I had bent the first side out 20 mm



so all i had too do was bend the other out until the gap was 130mm



then both would be bent equal , well close enough for this job.

the bit scrap that was cut from the box previous was re welded in at the front for the shoot to form a lip.






The shoot was then welded to the drop bottom .







would have took me 40 minutes if I did not stop to take photos  :lol: :lol: :lol:
