Today's work was making the rest of the whistle bits. The base was machined and hex cut in the rotary table chuck. Same went for the diffuser in the base, having 3 flats that line up with the ports on the whistle.

The base and diffuser were silver soldered with the smallest pieces that sat on the job before heating.

The centre rod and acorn nut were machined from 1/16" tobin bronze rod and the nut from 1/8" hex.

Fits together well and the onlookers should be pleased to see a small jet of steam coming from the whistle. The real whistle is to be under the smokebox.

Happy steaming!

Some jobs were done on straightening out the running boards and shortening screws for the frames. The sandboxes were trialed on the loco and seem to fit up OK just need some work to the sand pipes. Some 5BA screws were made for the crosshead pump also, I made these out of stainless to withstand a bit more side load and working that it will get.

I made a simple tool to shorten the length of some screws, basically a bit of steel that is the required thickness and with a number of holes in it to suit the various screw diameters. It has a tapped hole at the end and an M5 screw holds another piece of steel against the head of the screw to shorten. Same length every time with a nice square end.

Will come back to the Pansy after a stint on the Britt.

Happy steaming!

One of the interesting jobs done today was machining up the whistle from brass. It was drilled out with a slot drill and turned to make the chamber, and a collet made from hex brass to facilitate holding in the rotary table chuck for milling the 3 cutaways.

As you may be aware I've been involved over the last couple of years with drafting for the new build Victorian Railways V class 2-8-0 steam locomotive, assisting the Victorian Steam Locomotive Company.

Some more time was spent today drafting on the smokebox design. All the drawings are being done from scratch. We have the general arrangement and some Baldwin reference drawings, but all the detail drawings were destroyed many years ago.

The crowdfunding campaign is open for the smokebox project. Go to the website www.vicsteam.com for more information and where to donate for the construction of the smokebox barrel. The campaign is for $3000 and there's only $550 to go!

Happy steaming!

Some 1/4 size Victorian Railways loco number plates were made on the router. If you'd like some as well drop us an email!

Looking at a fundraising product for a Victorian Railways locomotive restoration.

The lubricator was stripped for a clean and inspection. First job was to cut more thread on the crank end of the main shaft to reduce the axial play. The ratchet and pawl were only half engaging so that rectified the problem. The piston and cylinder were stripped and cleaned and reassembled.

It was noticed the 4x mounting screws were a bad arragnement being only screwed directly into the tank and would be continuously leaking oil past the threads. They also had some 1/8" packers which were difficult to fit between the tank and buffer beam. So some blind  bushes were made and silver soldered into the tank to fix all these things at the same time. The lid was repaired at this time also.

The axle pump was dismantled and inspected and de-scaled in the check valves. The o-ring on the spindle was replaced with some graphite packing. The suction valve was noticed to lift up and partially block the suction port so the 4x grooves were filed deeper to allow more past the ball.

Happy steaming!

The brake crank bosses were made and silver soldered on to the cranks and the excess machined and filed off.

The brake shaft was machined as well to suit the cranks. The arms that hold the handbrake nut were filed and drilled out to size to suit the new brake shaft and silver soldered on. The end result is a very free and smooth operation completely unlike how it was.

All that remains of the brake shaft job is to pin the cranks to the shaft with some cross pins.

Happy steaming!

Something's up with my Blogger app on my phone so yesterday's blog below has been transferred to the PC, will see how it goes after reinstallation.

I've managed to free up the brake stand. The first mission was to dismantle it, I thought it had a tapered pin holding the bottom collar on and learned it couldn't be punched out with a pin punch. So the collar was turned off in the lathe. And the remaining "pin" drilled out in the mill which so happened to unwind...a 7BA screw!

The culprit was the handbrake stand has been drilled from both ends and the holes are slightly misaligned making the handle stiff. So the middle of the handbrake screw was relieved to only bear on the ends. Turns very freely now.

A new collar was made and a 7BA screw reinstated. Also the angle needed to be milled to remove the root radius to clear the nut. The nut was chamfered also.

The brake shaft bearings were shortened to not side load the handbrake screw with the lever and nut. These were set up in the 4 jaw chuck using a 5/16" arbor in the tailstock..a technique which I find very handy to square up and quickly centralise small parts like these.

New cranks are being made up from 3mm steel plate and round bar and will be completed tomorrow. Along with the new brake shaft.

Happy steaming!

Working on the brake gear today. The bits and pieces although made previously were tight, jamming, out of square, and not pulling up properly and require "fitting".
  
Some of the hanger pins were found to be bent and I made up a mandrel to hold them and straighten them in the lathe. I taped a permanent marker to the lathe tool to mark the high spot, makes it a bit easier. While at it the hexes on the pins were chamfered and cleaned up.

The brake gear was assembled several times and chamfers applied and swapping of parts around to get best fit, which is all time consuming. The brake gear is not adjustable.

There was some twist in the brake hangers also so they were gripping on one side first. That was rectified.
The spreader beams were still wrong...the front one was found to be bent. The threaded ends were redone to take out some lateral play.

The cranks need to be remade...you'll see why. The brake shaft has silver soldered ends...deciding whether to cut them off and splice more ends on or make a new brake shaft....which I think I may do.


The hand brake column is stiff when the engaging the nut. It could be the nut is cockeyed to the thread.

Happy steaming!

Today the brake gear was under repairs and assembly checks have revealed some issues to rectify. The side rods were catching on the brake block pins, and the hanger pins were close to the side rods also. These were all shortened up so they don't foul. While at it the brake hangers were dress filed to remove the burrs and sharp edges so the paint has something to stick to. The brake blocks themselves had a square edge against the flange root radius so the blocks were filed to suit.

A new brake cross beam was made to replace the bent silver soldered one.

The brake shaft bearings were renewed as the old ones were damaged probably by a derailment. Still needs some more work done to replace the brake shaft and cranks as the cranks and cross holes are loose and not on centre.

Happy steaming!

Pansy's cab plates won't be reused as they have too many holes in the wrong positions, so a new cab has been drafted up for laser cutting.  The removable roof and back wall section have been changed from previous to make for a better appearance.  The bunker can be reused, as it is quite a nice item.

The brake shaft, mounts and crank are all very rough items, and don't fit together well at all, so some new parts are in maufacture.

Will be uploading some pictures soon.

Happy steaming!

Some stainless 6BA cheesehead screws were made and the holes drilled in the firebox to mount the ashpan. Also the ashpan was sand blasted to remove the old paint and surface rust and some high temp black applied.

Trial fitted in the loco just fine.

Happy steaming!
