The minds in management work in mysterious ways. Wait till Nick Cave's "Red Right Hand" gets a blast in the workshop. Loud enough to do the dusting upstairs in the barracks upstairs.

"Wal is stoked, he has so far carried out management's plan for the door hinges. Also progress on the Smoke box door set up for machining. Trying out the Loctite holding process and so far so good, the workshop mob have never been down this road before."

The filling button collection is growing at the Llewellyn Locomotive Workshops. The smoke box barrel hinges parts are done.

Can you please explain? what are you holding with Loctite?
Not quite sure I follow...

btw - your filing skills whilst not surprising (after all you have plenty of practice in your daytime job) are very impressive

Another brilliant thread from you Dazza. I just love to see a master at work with so much detail. Thank you....

The blank for the smoke box door is parted off the lump of LG2 bronze that was left over from the cylinders and steam chests. Both have been faced, then Loctite back together using a 2.5mm pin to line both together. Then the curved front face with a changing radius and edges will be machined using the Turnado system when it arrives here at head quarters next week.

Then take to the mill for the slots for the stainless steel hing straps to sit into, heat up top break the Loctite bond and then braze the straps and then file the profile them etc.
Well that is the plan management intends to follow for making the smoke box door.

Filing for me is a chore, 40 years of nearly daily filing leaves me jaded with it, however thank you for the compliment. Much appreciated. I am off this weekend to the Rattler to guard tomorrow and then two days of firing and driving.

Thankyou , however I am not sure I am a master, I am terribly slow and I am just following what others have done many times before. I just copy techniques.

Look forward to seeing the results

Hi Dazzer,

Just in case no one else is a fan of where's Wally, I spotted Merv, lmao!

Have been away for a while and now catching up on your beautiful build thread and workmanship, keep it coming.

Best,
Tom

Management purchased a '"Turnado" turning system and it arrived yesterday, so last night the workshop crew made a cross slide attachment to fit the 254 and the spacers. A few first test runs just now. The workshop crew are impressed. This will be used for the smoke box door, domes and later buffer heads and what ever comes along.

The Llewellyn Loco works floor head reports that the door profile is done. The Turnado profile tools worked a treat. Next, to the mill .









File, sand down to 1000 grit

Door was held with a centre pin, loctite and clamp for the fear of moving. 0.30mm cut passes in fear. All worked out OK. Stainless steel hinge pieces underway. Drilling the 1.00mm rivet holes (decorative) wrecked normal twist drills, despite cutting fluid and sharp drills and avoiding rubbing. So out came the 1mm PCP board carbide drill which I have used before for 0.50mm holes. They make dust, not strings of swarf and hence do not jam or become blunt. Worked a treat .

Yes, stainless is a pig to machine
I like using these carbide PCB drills as well, although when they break they usually leave bits of drill in the hole
PITA to get out...
Nice work

I use stainless a lot in my work but not in small sizes, so far using my hand wheel feed on the mill/drill and the DRO on the quill Z I am yet to break one. But crikey I go at a 0.10 -0.15 mm per second with the feed. I broke one with the back of my hand when brushed it by accident when in the collet. Only run the PCB drills in good collets say I. Never a drill chuck. I never use a drill chuck with any drills in the mill/drill.

Fitting up the hinge straps. these will be brazed in and sculptured to appear like straps riveted on the outside of the door. I am yet to make the stainless rivets.











The workshop floor manager is always pondering the next step.

I do love seeing your progress Dazza. That door is looking great.

I couldn't possibly use direct feed on my Bridgeport for such small drills.
I use micro drill adapter:

Unfortunately my budget doesn't extend to $600 for such a thing, so I have Chinese knock-off
You get what you pay.... hence my experience

Not intended as a criticism, but presumably the smoke box will be painted so why not brass rivets? Certainly a lot easier to obtain and to rivet into place.
On reflection, having been following this thread for some time I am beginning to feel that you are perhaps a little masochistic and want to do things the hard way, whichever you are still doing a fantastic job on this loco.

Your "masochistic" is somebody else's "attention to detail"
No, I wouldn't use stainless either, but it is Dazza's railway
