Thank you Keith glad to see you back posting. Not sure about the craftsman bit just following the plans unlike yourself who builds from pictures and the like.

I am learning so much especially when it comes to the mill

Yesterday the long series drill bits and the long series tap arrived so got on with the buffer beams now they are all fixed in place. Now the first of the wheels are on the lathe no photos of that yet but a quick photo of the frame all assembled. I was very pleased the way it went together I did it on a surface plate to make sure the frames and buffer all sat square and level with no twisting in the assembly

Very well done above my pay grade.

Thank you Peter. This takes a lot longer than the wooden models I normally make, I needed something with a longer build time and have always wanted to make a live steam model. Yes it is a learning curve coming from woodworking hobby which I have not given up.
I have done a lot of reading and watching some of the more well known metal workers on U-tube

It's looking fantastic Derek.

Little wonder that you are happy.

Keep up the top work and the postings.

Have been working on the wheels this is taking a bit of time so far 4 days but that is not solid as I have the garden as well as other jobs.

Started with 6 rough cast wheels which are very good quality as far as casting go no blow holes either

This is what it looks like all that needs doing now is to make a mandrel and finish turning the outer rims

Well that is three down before the next stage three more to go then I will complete the rims on all of them as once the mandrel is turned I do not want to loose the setting of it while turning the rims

Hi Derek,

Yes - nice looking castings. Are they a local (Gt Britain) supply ?

Your loco is going to be a beauty.

Yes they are a British company that supplied them Kennions is there name we are lucky there are a few companies that make castings from stationary steam engines to traction engines. There is a few Australian model steam engine builders one is making the Ballaarat

Top video - Thanks Derek.

That little loco really packs a punch when it gets it's steam up.

Keith

Ballaarat manufactured by the Victoria Foundry in Ballarat, Victoria. Completed in March 1871. Cylinders 7" dia x 14" stroke. Drive wheels 3' diameter, Overall 18' 6" long, weight 9 ton. Gauge 3' 6". Cost 780 pound delivered to Melbourne. The locomotive worked in Busselton, Western Australia.

What is interesting is the valve gear works off the leading axle, but the connecting rod goes to the rear axle. Normal practice is to have the valve gear on the same axle the connecting rod goes to. In the case of Ballaarat the firebox is in the way.

Been a few day sine I posted I did have a hiccup with one of the wheels and had to order a new one anyway I have now completed all of the turning on them the first photo shows the final turning of the treads.

The wheels all turned and laid along side the completed chassis

Now onto the next job cleaning out all of the webs started that last night and managed to get one complete after drilling a load of holes to get started with. After just one it took it out on my hands as I was using a dremel. After this is done I will need to drill for the crankpins but I am waiting for a reamer to do that. Well now onto the remaining 5 wheels



DSCF2399.jpgDSCF2397.jpg

I am sure if it was me, I would not have a hiccup with one wheel, probably 5 of them so would be ordering another half dozen.

Keep up the good work and the posts.

Top work Derek,

The beauty about making a mistake is that you learn not to do it that way again.

It's looking fantastic mate. Excellent

Regards

Keith

Thanks guys yes mistakes are made but I got sorted in the end even if it meant getting a new piece and starting again. It was a moment of brain not thinking correctly I went to the drill rack for some drills to do the centre hole and knowing that I needed to end up with a reamed 7/16" hole I picked up the drill bits and by mistake grabbed the 7/16" bit which as many will know always drill over the stated size instead of a bit one size under so I could put a reamer through.
Yes there are ways around that but I would not have been happy knowing I had to modify the wheel/axle.
I am spending time cleaning out between the webs of the wheels at the moment so no photos, the reamer for the crankpin has arrived so they can now be drilled.
I did take a couple of hours away from the loco and turned a small bowl which I will put in the appropriate section on here.
