No need, it's bolted down onto the bed. Out of sight and just as strong.

Shopping and household matters ate into the morning but I persevered. Today's job is fitting the top lid.

Image

I need to divide the pitch circle for six studs. Lovely little job for Johnny's 1927 OT lathe.

Image

Here's an overall view of the setup. Mandrel disconnected and the overhead gear set up. That takes the time, marking the hole locations is a quick job and of course dead accurate. Simple dividing using the number plate on the bull gear, there's a 12 hole circle.... Trust Johnny to make it easy!

Image

Here we are ready for drilling.

Image

Here's the next set up. The lid has a register mark to locate it. The game plan is to complete one hole drilled and tapped, fit a set screw and that locates the lid for the other five. However, it was knocking off time. No rush.

I think this set of pics tells the story of my hour and a quarter in the shed this morning. Quietly away and lots of concentration. I find white knuckle work like this very tiring! I don't have a good reputation with small taps! However, as you can see, I have achieved my goal, all the top lid studs installed. When I got to this stage I decided that a bit of tackle tidying was in order but not too much as the next job of the valve chest studs is going to need the same tools. By the way, no gloves this morning you need a lot of touch and feel to work with 7BA. The tweezers are invaluable as well!

Is it me or is that lid offset slightly in relation to the cylinder?

No you're right Ian but that will be adjusted during the process of fitting and will be OK. Don't worry, it will run and nobody will see it off the Ribble!

Image

New taps and abrasives landed. Takes some pressure off!

Today's little job is to get the steam chest lid ready for using as a template for drilling the steam chest and valve face ready for tapping for the studs that hold it all together.

Image

First job was to make sure it was exactly 1/8" thick, these studs are not going to be over generous in length. Then an hour spent carefully measuring and marking the stud holes. Good and careful work. Last job before knocking off time was spotting the locations with the centre punch.....

Image

Into each life a little rain must fall and I had a short sharp shower. Note it was the last hole! I examined the metal carefully under a glass and there is a tiny inclusion exactly where the punch mark is. These things happen, especially with castings. No point getting into a lather. 3 hour's work in total down the drain. Ah well, onwards and upwards! (Far better that it's happened now and not when I was fitting.)

Does the lid have to be CI Stanley or can you just make another one out of stock you will no doubt have?

Better if it was cast iron Ian to match the rest. I have some odd bits about my person, should be able to find some.... If not steel will do OK.

The design committee had a meeting last night and their conclusion was that the broken lid still had value, the carefully measured drillings. So the first job this morning was to drill them all tapping size for 7BA. It will now become a template for the new one, saving all that careful work laying them out.

Image

It's now a template!

Image

Then a search though the treasure chests, one outstanding candidate, we can still have a CI lid. Now for a bit of marking and cutting.

Image

The slitting saw in the horizontal mill is the obvious route but recognise that before I got to this point the vise had to be re-installed and trammed in. It all takes time and isn't as simple as it looks so don't be criticising me for being slow!

Image

Two set ups and two cuts....

Image

Here we are at knocking off time. Tomorrow is clear, the blank has to be cut to size and thickness before it can be used. (I might even punch the marks into it before I do the final reduction in the thickness. I don't want a third stab at it!) Nice morning, I enjoyed that.

Why bother with the punch? You have a number of purpose made centre dills and a stiff enough drill unit to go straight for it. You should know by now not to hit cast iron with a hammer.

With the now template on top, in effect you already have a ready made deep punch hole so I would concur with P on this

It looks like you've got to remove a lot to get it down to 1/8" thickness [Quote: First job was to make sure it was exactly 1/8" thick, these studs are not going to be over generous in length.] Just a reminder, don't do the marking and then find you've erased it!

The stack is going to be high enough when I get round to drilling and the way I shall do it is get two opposing holes drilled and located with studs so the template won't fit after that.
Reducing the thickness is easy China, not much for my El Cheapo mill and sharp HSS cutters!
Nothing wrong with punching cast iron, all the other locations were OK, it was the inclusion that got me and that's just a matter of luck.
These things happen, it's how well you retrieve the situation that counts, all part of the challenge!

It's the new lid... Not milling for size here, all I am after is square! Good start yesterday when I trammed the vise on the HM in, I must have got it right because the two cut edges from that cut are at right angles to each other. A good start!

Image

Once I had it square, a bit of marking up and now I am milling for size.

Image

We have the right size, it matches the chest exactly.

Image

Next I want one clean square face. One cut got me there.

Image

Both the bad lid and the new one degreased. This is because the design committee came up with a change of plan. The game now is to super glue the broken lid to the new one for drilling the holes.

Image

Glued in place. At this point I looked at the instructions (typical Stanley) and realised that full cure necessitates leaving it for 24 hours.

Image

So I put the assembly under pressure in the vise and called it knocking off time. I am sure it would have been OK but I am in no rush, far better safe than sorry.
In case you're wondering, a bit of heat will break the seal when drilling is done. If not, the old lid can be milled off so it can't be a problem.

Image

The lids stuck nicely. First job was to drill the hole pattern

Image

A bit of fiddling to get entry but then I managed to split the two lids.

Image

Before I reduce the lid to 1/8" I dressed the stone and gave my cutter a careful lick to ensure it was as sharp as possible.

Image

Quite a lot to come off and only just over 1/16" hold in the vise so a succession of small careful cuts until I was down to size.

Image

Knocking off time. We have a lid and the drillings, whilst not dead accurate are perfectly adequate. That'll do, I have a busy morning! By the way, the larger hole is where steam will enter.

Image

First job this morning was to put some finish on the valve face. I've just bought some new high class abrasives so I just rubbed it on there instead of lapping it as I normally do.

Image

That'll do nicely.

Image

Then consult the drawings and sort out the studs that are going to be used. Tweezers invaluable.

Image

Then set the cylinder up with the chest and the lid clamped and adjusted in the right place. I measured the depth I had to drill to, set the tapping drill up and drilled a couple of the holes by hand, the easiest ones to get to. It was at this point that things started to go wrong!

Image

As I was drilling the second hole the drill broke. Unusually and fortunately it broke at the shank and not in the hole. (I found out why later.... )

Image

I shame to put this pic up but it shows what went wrong. I have to face up to the truth, my eyes are not trustworthy any more. I was certain I was drilling at right angles to the work. This demonstrates how bad my eyes are! I had a rethink. Recognised that as well as my drilling my original marking was lousy. I did some thinking, set the steam chest and lid up under the Progress drill and put my mistakes right. I was doing so much thinking I forgot to do a pic.

Image

Here's where I ended up, luckily no damage to the cylinder body and valve face, just the lid that needs rectifying and one tap hole on the valve face that is way out from where it should be, Tomorrow I'll tap the holes marked with a cross, tap them and plug with 7BA studding and finish flat. They'll never see it off the Ribble.

Image

You can tell I've been thronged. This morning was halting progress, once I have plugged my bum holes I shall be back on track!

A few weeks or months ago I asked if 3D-printing would take over from casting. Your reply went along the lines that it would be difficult with the high temperatures involved. Today I was reading an article about using 3D-printing to produce medical implants from Tantalum which has a melting point of 2996C. Bet it costs more than casting! I've heard that some complex rocket parts are produced this way also.

Shed is going to be further delayed as I start immunotherapy again on Monday, I shall have to see how side effects hit me. The usual one is extreme fatigue. Never mind, things don't rust in my shed due to the CH and I am going to live forever so no rush!
