I'm with Mike. I'm also in favor of the simplicity of a VFT for "hobby" steaming, despite the improved efficiency offered by that more complex design. I see the need for at least 8 different bending jigs to make that boiler design. Not so much a Home Shop operation. RussN Or one, multi-purpose, adj...

Mike, a lot will depend on the type of bender employed, some cheaper one are definitely not up to muster, it needs one with a supporting die on the outside of the bend, such as, https://rothenberger.com/ae-en/pipe-bender-multibender.html. It isn't a good idea to bend too close to the open end of a p...

Some considerable years ago, when building a small loco boiler in copper, I was advised to price the copper and then double it to allow for the silver solder. I don't think the advise was far wrong!

Nice one Pete, it seems my postulation in our email last night was close to the mark!

I'd suggested to Pete that there must be many boats out there with mismatched boiler/engine/prop configurations. Pure guess.

Whoops! I walked along that pier to peer at the JOB when I was in Frisco in 2005. One hopes it was accidental and not some idiot with a match.

I have eventually got round to clearing the decks and grinding the slide-bars. As suspected, I beat the tolerance of the manufactured material with exact size, i.e. NO tolerance at all! DSCN7547.JPG Their size was no better than (quoted) 0/+0.002" thickness x 0/+0.008" width. Just wondering whether ...

Cheers Fred, those sizes work well, I was hoping to get away with something much shorter, but I'm not sure yet, I haven't put any final thoughts Pete's way yet, or drawn them.

I'd like to ask what dia. and length of shaft is envisaged?

Surface grinding has not been on the menu, due to too much 'stuff' in the way that needs to be moved before it can be used, and then put back afterwards. It includes cars and locos that can do without being splattered with grindings. I will get to it sometime. Instead my thoughts have moved onto the...
