That's a nice looking build  :ThumbsUp:  :ThumbsUp: As you say the designer seems to like brass  :)
Best regards

I like working in brass too, be nice if I had bought lots more a few years ago before the prices went so high!

Thanks Bill - I've never attempted a project this big before, but Kozo's instructions take you through one little part at a time with very good methods, so I am having fun with it.

Couple rainy days, so good time to play back in the shop! Got the rest of the boiler support brackets done this morning.

I am trying another way of hosting the images, hope they come through okay...

The adjustment plates and the rod end plates were gang drilled

and milled

from longer pieces to make it easy to hold/align in the machine vise,

then cut apart and trimmed to final length

before soldering onto the rods on the brackets

and the rod ends

before assembly onto the model.

It is starting to look like a loco, little by little!


Next up are the angled brackets at the ends of the main rails - those look like they will be tricky, getting all the angles in the right directions....

Not for me. I just see a little box with an "X". Maybe you are a member of the Home Model Engine Machinist forum, and are logged in?

Now I'm getting boxes with X's, it was ok just now  :headscratch:.

Went over there and logged in, came back and still boxes with Xs in them  :shrug:

Okay - it was worth the try to cross link them that way, guess it was not a great idea. The photos are attached to the post in the normal way too so you can see the same shots that way, just not in line with the text. I'll go back to the normal attach way from now on.

Yeah - a small machine CAN turn out a big project!

Kinda surprised myself how quickly this part of the build has gone - the main frame is done and ready for paint. A bunch of days I got going back in the shop, until looking up at the clock and going 'WHAT time is it??'. Sure ign of a fun project! Most of the parts so far are nice easy square shapes, but LOTS of little holes to tap....

Most recent parts were the angle braces at the ends, which have lots of odd compound angles to drill/solder at, fortunately Kozo gives detailed measurements for the parts and the soldering jigs, so they came together well.

After that was a set of floorboard brackets, simple blocks, angled on bottom, and drilled using the template made at the start so they all fit perfectly (the jigs for multiple part drilling were well worth the time to make).

Then, it was down to the floorboards - to drill the holes for those I put the whole frame up on the mill table, you can just see the low-tech machinists jack at the far end (two carriage bolts/nuts holding a crossbar) to support it during drilling.

Once all the holes were drilled at tap size, the boards were pulled off and drilled/countersunk for the flat head screws used to hold them on.

Ready for paint now, got some hi-temp paint that I need to test in the sprayer...

I like that mill set up! :ThumbsUp:

Very creative!   Should work just fine, and pushes the limit of a small mill!
