Got back to work on my latest project; beam engine, machined up the crankshaft / webs. Remembered to polish up at this stage as it makes it easier in assembly stage. All the shafts are press fit into webs with a touch of Loctite 603. Maybe I should drill & pin the bottom end shaft... thinking

Well if you were asking me George, pin them. Belt and braces job!!!!

I have some 1/16" panel pins which mike up at 0.061" perfect with a 1/16" drill and drop of loctite.

Nice work George

I've occasionally posted on here my progress building my Lion boiler, I had taken lots of video and have decided to have a bash at building a video series of my build.

Today I uploaded my second video, for any one interested here's a link: Lion Boiler Build pt2

Part 1 is an introduction which is here :Lion Boiler Build pt 1

Here it is finished, now I'm busy with the frames, horn plates and wheels.

I hope my videos help anyone thinking of building a model of this historic loco.

 

BTW, Very nice work George on that crank.

 

Nigel

In order to use my insert face milling tool on the horizontal mill I need to make a new drawbar with an M16 thread on the end instead of 5/8" BSW. This evening I hacksawed the appropriate length of 16mm diameter EN16T and cut the M16 thread. While I've screwcut many dozens of threads on my imperial lathe this is only the second metric thread I've cut, and the first one must have been 15 years ago:

m16 thread.jpg

Since this was a metric thread on an imperial lathe I couldn't use the Ainjest high speed threading unit, so I did it as per the manual leaving the half nuts engaged at all times. I started at 58rpm and dropped to 40rpm as the thread got deeper and I needed to be quicker on the tool retract. The insert tooling left a reasonable finish. It was a bit slow going but at the current rate I'll have kicked the bucket before I need to cut another metric thread.

I know the feeling, I also get a mention at our CC dinner for similar services rendered. No cup but I always get a few free pints.

With a colleague, attended the boiler-testing seminar hosted by Cardiff MES - we were very impressed by the track and club-house - and by the catering!

A valuable session, learnt a lot.

Many thanks to all.

I have just stumbled across this interesting document entitled ‘Gear Errata Tables’

**LINK**

https://www.model-engineer.co.uk/sites/7/documents/gear%20errata%20tables.pdf

That title is somewhat cryptic, given that ’errata to what’ is not specified dont know

Can anyone advise, please ?

Did a late night cooking job on the Water Cart wheels last night. Long job setting the individual letters around the hub faces. Had to cook one hub twice, as one letter chose to stick to the retainer washer, rather than the hub. Pleased with the result.

Initial check for size and placing the lettering for spacing-hubs.jpg

On removal of the retaining washer after cooking, the sweated the lettering all in right place on first hub-

Partial clean up of the second hub shows promise-

Bit more maching on the hubs, then rivet to rims time.

Edit-PS Mods. should've really posted in the Workshop Prog forum. Happy if you want to move it?.

Finished off polishing the tiny bell crank link for my beam engine, then went on to start marking out the cylinder from a machined up piece of brass ( didn't get a pic today, next time thinking ).

Fitted a cheap digital tachometer to the crusader today.

Since fitting the VFD, I've been a bit lost with speeds!

Works great!

Finished boring out 15 mudhole doorways for an 8F loco in rebuild at the railway. They were black MS about 4.5" diameter x 1.75" long, with an oval recess about 78 x 90mm x 3/8" deep already CNC milled in one end. I had to bore 'em about 91mm diameter from t'other end to meet without chopping into the 3/8" wide elliptical shelf.

Sorry about the mixed UoMs, but I work in whatever's convenient, and I had a metric Ward 3db to do it on.

I'd already stuffed a succession of drills through the blanks, culminating in a 45mm., which I think is the biggest the turret sleeves would hold.

The machine's solid with a lot of grunt, which I was grateful for as there was nearly 14 cubic inches of steel to cut out of each blank. There's another volunteer who'd partly set it up, but I couldn't get his boring bar to cut - thinking about it since, that might've been due to a negative rake setup that'd rub on the lower edge of the carbide insert if the cut was less than a millimetre or so. Any road up, I substituted my own setup using another tipped boring bar. I found I could take 4mm depth of cut, with a generous suds flush giving - most of the time - a well-broken discontinuous chip flow. Reminded me of some of the work I did in my 20s, back in the mid-'70s.

The things still took me over half an hour each, and it was fiddly getting the depth right on the Ward, probably because I don't know how to set the saddle stops. I think t'other volunteer does, but I doubt he'd be happy to have his brains picked. Anyway, the bits are done, and although it was interesting, by the time I was finished I was glad to see the back of 'em.
