Hi
Thanks cnr6400
I have been watching my mate Julians build of his Simplex 0-6-0 loco. We have had the initial twice working pressure test on our boilers and passed that ok. The next boiler test is 1 1/2 times working pressure hydraulic test with the boiler in the loco and all the fittings and pipe work connected. This is where Julian is suffering a bit. Every time the boiler is stripped out to carry out other work then refitted he plagued by leaks
So with that in mind I am aiming to fit my boiler just the once. Everything else must be done and ready.
The running boards are on. Both side tanks are now made and leak free.
I am now making the cab. I want to be able to lift the cab off by removing no more than 6 bolts
I have had to cut 2 slots in the cab front to clear the by pass valve bushes in the back of the tanks
Satisfied that this will work ok its time to cut some metal. The cab I am making from 2mm thick ally
To cut the large hole for the boiler I set up on my home made rotary table with sacrificial MDF. Then the band saw to remove the waste
The 2 slots were milled out. The windows were cut with a hole saw
3/8" x 3/8" brass angle can be curved by teasing it round gently a bit at a time
Attached with 1/16" copper rivets
The 2 cab sides are also made from 2mm ally and machined as a pair. The hole being cut with a 75mm hole saw
Brass angle is used to fix the cab sides to the cab front.
A lapse in concentration and I drilled the holes for the rivets in the wrong place
Some car body filler to rectify the ermmmmm error
To amuse myself while the filler sets I have made some beading.
A scrap of MDF has a 3/16" wide 3/16" deep slot cut around 8" long. The Y axis is locked so that the table stays in place
Tap in a length of 3/16" copper brake pipe
Now with a 2mm cutter machine a slot along the pipe
I will upload a bit of video later
The cab side has been temporarily fixed to the cab front with 3 x 1.5mm cap head screws and nuts for a trial fit with the 2 tanks
Cheers
