Pewter Repair

[megagreg]

Hi all,

So I'm in the middle of my first SidKit build, and I've ran into a snag. Seems that the pewter was very thin near the back wall of the bulldog frame (where the cylinder would pop out). And while polishing this piece, I polished right through metal leaving a hole (see image).



To compound things, the spring loaded ejector pin/pivot (see image) now gets stuck in that hole every time I eject the cylinder. So I can't completely eject the cylinder without a lot a wiggling and wrestling the blaster.



Anybody have a repair technique for filling that hole?

Thanks much!

I would recommend filling the damage with http://jbweld.net/products/jbweld.php
JB-weld is safe for use and bonds to softer metals. It's pretty easy to sand/paint after curing.

Your finish is looking great btw...hope to see some finished pics!

You could repair the hole with a good lead free solder , simply 'blob' solder quickly into and around the hole , don't leave the soldering iron tip against the surface of the pewter gun for too long or you'll cause more damage than trying to fix the repair , you should end up with a raised 'pimple' of solder on the surface , file or grind it down with a dremmel again not too much grinding - finish with filing and sanding it smooth .

Thanks guys!

Some JBWeld is sitting right in front of me as I type this—so I'll probably try that method first. And I'll post some photos when the build is done.

All the best

JB Weld worked great - thanks again! (solder might have been even nicer (a actual metal finish) but I was too chicken to try that method).

Great repair job there mate…!!

Looking forward to seeing the rest of the build completed.

Regards

I agree looking good, whatever works best - since I'm electroplating mine , I'd have used solder rather than epoxy , since , I need a material that's conductive - looking forward to seeing teh finished article

Very good repair MegaGreg! Looking forward to more pics of your build.

Thanks all !

Still working on it, but here's a sneak peak.



Still to do:

- electronics
- weathering & detail
- fix upper receiver and barrel alignment

Need More Help: What kind of battery is used in the SidKit? Mine came "batteries not included"

See here:

Thanks again !

You can use a 9v flat battery, which I am told Sidero always used, my Sidkit has a 9V inside, or as Rich does a 3v camera one ,the only thing to make sure about is the wiring for the LED's and the switch , and protect the circuit with a small resistor , if you don't know the specs on the LED's as an unprotected circuit and unknown LED's could cause them to overheat and burnout.

Lookin' good...keep up the good work

[megagreg]

Thanks propsjonnyb

From the online instructions: ( http://www.heycomputer.com/instruction/blaster9.htm ) it looks like a 3v camera battery is being used. There was no resistor in the bag of electronics that came with the kit, so I'm thinking I don't need one for a 3v configuration (as opposed to 9v)? ?

[propsjonnyb]

It depends on the specs of the LED's , if you don't know them assume 300 ma and add a small resistor, just to protect them from burnout , if you wire up the LED's incorrectly the circuit could get pretty warm and blow an LED damm shame if you've fixed it in place , most LED's will happilly work forever on 1.5v so try to keep it around that limit, the photos show them linked in series , I'd add a 10ohm or12 ohm resistor just to be on the safe side.

Great advice! Thanks much propsjonnyb. Off to the electronic store…
