Re: Rebuild of an Allen Mogul.
Lots of cylinders are made from gun metal bronze, still, my friend that ran commercial boilers likes to remind me that steam will erode bronze over time.

Re: Rebuild of an Allen Mogul.
Well, I say don't reinvent the proverbial wheel. The original design is for cast iron, and there is a boatload of them out there, some with thousands of miles on them. We know iron works, and if you have experience with iron from motorcycles, stay with that.utahwestie wrote: ↑Tue Nov 26, 2019 9:13 am

My question is, which material should I use for the liner? in the vintage motorcycle world( another obsession) we use cast iron. I've seen many references to using 660 Bronze.
What are your thoughts?
Cheers

Re: Rebuild of an Allen Mogul.
Hello All,
Thanks Greg for that little insight it was just what I needed to help make a decision. I will be making the cylinder liners out of Cast Iron.
With work being needed on the journal boxes to make them all the same and to the print,next axles needed. I decided to convert to roller bearings in the journal boxes. I also made the journal boxes all the same size and width by machine the boxes to fit wear plates. As you can see the axles had been well used with a couple of efforts to get the timing correct. Every end of the axles were a different size, so the hub diameter will need to be made correct on all the wheels.
I did have a plan to have it sitting on its drivers before the end of last year, a few weeks behind but still moving forward none the less.
Cheers

Re: Rebuild of an Allen Mogul.
Any idea what happened to Anthony?
Re: Rebuild of an Allen Mogul.
He was last on the board on November 23, this year, so he may not be adding to this thread any longer.

Re: Rebuild of an Allen Mogul.
Thank you Harold.
That would be a shame.
Lots of info on his rebuild.

Re: Rebuild of an Allen Mogul.
Hello All,
Long story short, I had a major change around in my life, started new job, having brought my shop back to the my house, having to build new shop area at back of garage.....
But on a positive note, i've lined up all the parts again, dug out the blueprints and am about to start work back on the mogul. Looking back at the thread, I need to update the thread as the project was further along than I last posted. So, I'll work on that over the next few days..
Thanks for the interest.

Re: Rebuild of an Allen Mogul.
Hello All,
Well, I'm back at the Mogul project. I'd lost a bunch of photos of the project, which is a shame as I enjoy reading all the comments/ideas and suggestions on how to do, or how its been done.
Here is a few updated pictures, Smoke box saddle is complete as per the prints. Its painted with a high temperature coating that is allegedly rated up to 1800 deg F...
Cylinders have been sleeved , bored to size. New pistons have been made from Cast Iron bar stock. These are all now the correct and same size. There we're different rom each other and the dimensions.
Cylinders have also been re-machined to align the threaded holes for both front and rear head caps. However, the rear head covers have been machined "funky" and not to the prints. So, after I write this email, I'm hoping to call Steve and get some new castings coming...
Wheels, frame rails, new cast iron apron, leading truck are all painted. At the shop today painting the cylinders and other various frame pieces.
Onwards and upwards, I'll keep moving forward as I'm hoping to be doing steam trails this spring. With my Dad coming up from New Zealand late this summer, my goal is to have a day steaming it with him here in Salt Lake City...

Hey Anthony, looks like it's coming a long great! Hopefully we'll see it fired up this summer at S&S.

Re: Rebuild of an Allen Mogul.
Hello All.
Moving along with the project....
I purchased some brake cylinder castings that had already been started, unfortunately the bottom cylinder head was now undersized( to print ), I had also purchased a set of un machined castings from PostWarBob...but I wanted to try see if I could save these.... So never minding the undersized OD , we'll make the rest to print. I'm thinking I may have to make the piston rod over size also due to the through holes on these not being in the center.
So I'll do the best I can... Chucked them up in the lathe, dressed up the angles and made them to length. I still need to flip them around and finish the backside. I'll use the remaining pre drilled holes as they measured accurately, but I'll also run a spot face tool to make a flat mating surface for the hardware...

Re: Rebuild of an Allen Mogul.
If the through holes are off, could you plug them and re-drill them?
