Hi, assembled Mayhemmers!

If in doubt - ask!   So here I am asking.

I have printed most of a clyde puffer, the same basic model as in RSTs post dated 26 Jun 2021

<<Hi,[/size]Not sure if anyone is interested but along with VIC 56/96 type puffer there is now a more regular VIC puffer on download from thingiverse.  I'm playing around with one -just the hull, everything else I'm doing myself.  It's about 1:48-1:50 scale (my favourite scale).  I'm not sure whether I'l finish mine as an original or as a modern tourist steamer yet like VIC 27/32 (if I finish it, it's yet another work in progress again).https://www.thingiverse.com/thing:4832191https://www.thingiverse.com/thing:4254426

  Hi,
  
  Not sure if anyone is interested but along with VIC 56/96 type puffer there is now a more regular VIC puffer on download from thingiverse.  I'm playing around with one -just the hull, everything else I'm doing myself.  It's about 1:48-1:50 scale (my favourite scale).  I'm not sure whether I'l finish mine as an original or as a modern tourist steamer yet like VIC 27/32 (if I finish it, it's yet another work in progress again).

And need to assemble the hull parts which are printed in thick PLA resin
They are not flat or good joints, so I fear that I need filled Epoxy to join them.  But I would like to know more about good ways to join printed parts

Solvent glues?  I have read very mixed reviews, but gather that Ethyl Acteate is a pretty good solvent.  Any other ideas or experience?

Aircraft printed parts I have joined with medium Cyano, but these were pretty close-fitting.  Tia,andrew

We use superglue, but beware, it is brittle once dry

[SteamboatPhil]

Are you going to put a nutter brushless in it Andrew

[Martin (Admin)]

Epoxy works well too...

[andrewh]

Thanks for the replies


Klunk - Yes, I'm aware of the brittleness of Superglue.  Not very water-resistant either, but usually well protected by paint or something similar


The Puffer will be assembled (possibly this evening) with Epoxy filled with microbaloons, Martin, because of the uneven joints and gaps. 


Phil:  [size=0px]Are you going to put a nutter brushless in it Andrew?  [/size]
[/size] I am SO hurt that you think that of me [size=0px]


I am not sure at all that it will ever sail, except perhaps in the bath domestic flotation test facility as the upper works are HEAVY when printed but I might reproduce them in styrene/ply/balsa.  There is a shaft tunnel moulded in, parallel to the bottom, and this would limit the diameter of the  motor that could be fitted - Don't think there would be room for more than a 385 and maybe not even that


The whole printed boat was to find out what the printer can do, and I just like puffers!

I use Plastic Magic from delux, it melts PLA and make a strong joint

Thanks, Tica
That's what I was hoping to learn


Now all I have to do is to find some in Australia

Many thanks, HMS Invisible


That's just what I was looking for!


Regrettably my Chemical nomenclature dates from the 1960/70s and interestingly so does the language of the MSDS, although one the tables also gives it the Systematic IUPAC name


A little search shows that Deluxe do distribute their products in Aus.  Not accessible to me now because I'm in a wheelchair ATM and not able to drive.  It will have to be Epoxy at the moment, just as soon as I can find my supply of microbaloons


thanks
