Tony,
I just caught this. I'm with Brian it's a great steam punk sort of idea. I love the concept.

Time has been limited this weekend but I did finish getting the tubes swaged. After looking at my swage job I decided I better hard solder the tubes in just in case. Here is the fire tube assembly out of the pickle.



Next up I will drill the main body and start riveting.

Till next time

Tony

That looks good.

What kind of equipment did you use to do the soldering?

Zee, I used a basic bernzomatic torch with a propane tank in it. I didn't even need to bust out the tank of map gas for the job. The solder was siverflow 55 solder with tenacity 5 flux.



It took quit a while to come up to temperature but tenacity hung right in there without burning. It's good stuff.

Thanks. Good to know.

I always wonder if I have the right tool for the job and would hate to get half-way in, ruin the job, and realize I had the wrong tool.

Is that a small belt sander behind the flux Tony? More pics if so please.

As requested, here are some pictures of my 1 inch belt/disk sander. It's not bad for a light duty unit. You can get the them on Amazon for about $100.

I have the Dremel version of that sander, very very useful for rounding the ends of small parts without setting up the mill and rotary table - use it a lot.

Thanks Tony, it has a nice small footprint which I like. Oftentimes don't need a more powerful unit for rounding small parts like Chris mentioned.

Time for the next update. With the tubes soldered it's time to work on the shell. I glued the template to the shell and drilled all of the holes for the bushings and the mounting screws. I also drilled the corners for the firebox cutout.



Next I spent some quality time with my jeweler's saw to cut the firebox opening.



Then over to the mill where I picked up the rivet holes using the laser and then drilled them.



Here is the boiler with all of the rivet holes drilled.



Now those who have made one of the PMR boilers may be wondering why I haven't made the riveting tools called out in the plans. The reason I didn't make them is I have a secret weapon from my aircraft mechanic days that is perfect for the task. Meet the rivet squeezer.



I hade to bust out the big anvil but the tool made short work of riveting the boiler. I mean that literally, it took a little more than a half hour to rivet the boiler together. Here is the final result.



Till next time

Tony

I had made one of the rivet squeezers, copying the one Florian did - they are very handy as long as you dont need to get too close to a corner.

What are those post thingys holding the parts together till they are rivetted called? I've seen ones like that used in pictures of airplane factories, and there is probably a better name than 'post thingys'!

Chris, they are technically called pin clamps but everyone in the aviation industry knows them as "Clecos" which is a brand name.

Part of me wants to call 'cheat!' 'cheat!' but I'm too envious.

Looks great.  :ThumbsUp:

I'm taking a break from my hurricane prep so I thought I would try to get this build log caught up. After riveting the boiler I tried to solder it with my hand torch without success. I did some research on the forum and ordered a turbo torch setup. It is similar to the Sievert torches you guys use in Europe. While waiting for the kit to show up, I worked on some of the other parts. First up was the base. I faced the bottom flat and cleaned up the outside.



The base was flipped and turned down to fit in the boiler shell.



Then over to the mill where the mounting holes were drilled.



Then I turned the base on its side and drilled and tapped the mounting holes for the boiler shell.



With that done I started working on the top cap. I mounted it into the lathe and turned the top part. Next I bored the top cap to take the chimney.



The part was flipped and turned to fit in the boiler shell.



Then I put it in the mill to drill and tap the mounting holes and mill the recess for the safety valve.



Next up was the chimney top cap. I started by boring the inside diameter and parted off.



Then I made a form tool in some A2 tool steel and cut the final profile.



By this time my torch came in and I soldered the boiler. After soldering I pressure tested the boiler and found numerous pin holes and seeps.



I'm still working to address those issues. Right now the boiler is on hold until after hurricane Irma.

Till next time

Tony
