I grafted some wee PE bits onto the starboard bow... flood holes.
The molded holes are just plain bad, due to the limitations of molding (I guess).   

The PE flood holes are soooooo much better!

Stern PE flood holes
« Reply #16 on: 03 Oct , 2016, 20:43 »
Grafting the PE flood hole template to the stern ventral hull was a piece-o-cake in 1:144 compared to 1:72 scale... it was 1/4 the work!
The dime shows the diminutive size of the parts.

Resistance soldering... THE thing!
« Reply #17 on: 08 Oct , 2016, 18:41 »



Wow, I wish I had discovered resistance soldering years ago.
Soldering has never been so easy & stress-free without the fearing of burning myself.


Pic 1:
My recent thought to use a grounding platform was the proverbial lightbulb going on above my head.  My homemade grounding platform had a grueling debut, and it performed flawlessly.


Pic 2:
Using resistance soldering to connect the 3 pieces of the long PE deck (only 0.007" thick). I put a piece of tape on the platform below the weld joint, to prevent the solder from fouling the copper plate. Then I taped the PE deck to the platform... instant grounding!   Soldering after that was quick & easy.


Pic 3:
I soldered pieces of 0.015" brass wire to the underside of the PE deck, to raise if off a plastic baseplate (to go underneath).
1. Cut brass wire to length.
2. Dip wire in solder paste.
3. Hold wire down onto PE deck with finger, zap with electrode to solder it in place.
4. Repeat, repeat, repeat...

Hi Glenn,


Are you using the other 'secret' ingredient, low melting point solder?, e.g. Javis LMS 145 designed for brass. 138 deg solder paste available readily from ebay from China.

Hi Jon,

I am using and old batch of Koki solder paste (unsure of the composition) that Sierra recommended a long time ago.

Do you have a link for that other brass-specific solder paste?   
I searched on eBay for the Javis LMS 145, but only found solder wire (not paste).
I do not use solder wire any more, only solder paste.

Cheers!

Hi Glenn,


Javis is only sold as wire.
SD528T is the equivalent solder in paste form.

What are you using as an RSU, home built or store bought?

Solder paste, RSU
« Reply #21 on: 09 Oct , 2016, 15:09 »
Hi Jon,

Thank you for the link!   Some day I may run out of my current batch... maybe in 3-4 hundred years at my current rate.  LOL   
Mine is in the same type of dispenser syringe.

I have a very basic, store-bought RSU that I got from Micro Mark a few years ago:
http://www.micromark.com/microlux-resistance-soldering-unit-with-single-electrode-handpiece,10952.html

It was always awkward to use because of the grounding cable.
Now with the grounding platform I made, it is sooooooo easy (and burn-free) to use!

So, Glen, Koki can be melted easily by the monopolar electric solder? is that correct? better results than the hot blower technique? if so this might change my life for the better
*(by the way. I dig your excellent wip, as usual)

Oh yes, SG... solder paste is bloody marvelous & easy to use. 
It even sticks pieces together lightly, then you zap it... and it is nearly instantly soldered in place (maybe 1-2 seconds, tops).
A hot air blower was better than a soldering iron, but you still have to keep it running (and that means contending with a hot metal tip).

RSU + solder paste was a game changer for me.  :)

I made good progress on the ribs & deck of the VIID during a day-long build day:

PE deck details
« Reply #26 on: 13 Oct , 2016, 08:19 »
A day home (due to a root canal) let me get some bench time, so I started adding PE details to the deck.   
With the teeny weeny parts, I may just go blind.

Nice progress Glenn, I have to keep reminding myself that it's 1/144!

Thank you!
I am reminded of the small scale with every teensy-weensy detail that I add.   LOL

VIID progress 15-Oct-2016 :: Soldering & more soldering
« Reply #29 on: 15 Oct , 2016, 09:52 »
Roughly 140 pieces of brass wire "ribs" were soldered to the underside of the PE deck.
Worth the effort?  Yes.
Viewed from the top of the deck, you cannot see the ribs, but they are there doing their job.

Also soldered on a bunch of hatches.

Getting there...
