Jojo, powder coating na kasi ngayon ang uso, at much cheaper in comparison...about three or more times the cost...meron anodizing sa mandaluyong pero gusto maramihan, ayaw nila ng paisa isa...

oo nga eh, meron naman tayo plating and powder coating pero yan anodizing talagang mailap kaya naisip ko pag aralan. yan nga nakakainis, gusto nila may moq eh pano kung isang prototype lang gagamitan like sa mga projects natin di nila pinapansin.

nga pala, merong grinder attachment sa pag hairline finish ng metal, nakita ko kay Peng sa T.Alonzo, Unity Metals...

JojoD818 · « **Reply #12303 on:** Feb 12, 2018 at 08:44 AM »

aba gusto ko yan. nagbebenta sila o gamit lang nila?

tony · « **Reply #12304 on:** Feb 12, 2018 at 10:23 AM »

nakabili na ako ng flysander attachment sa kanila, 25 pesos lang, at okey naman, ask mo si Peng mabait naman sya...

sige nga baka mas mapadali kung may help ng power tools. may jig naman ako para siguradong diretso pero kung meron de-kuryente aba mas ok yun hahaha

ayaw ko sana mag ikot sa area na yan, ang daming pwedeng bilhin eh.

last Sunday's "weekend junk build"... needed a more heftier constant current power supply for my anodizing rig so junk parts to the rescue. upcycling is good for Mother Earth.

first, scrap pieces of "paleta" wood.for the case. nothing fancy, just need something to screw all the pieces onto

kaysa matuyo lang sa lata, I applied some leftover stain and sanding sealer

putting the scrap electronics in... used transformer, scrap heatsinks, salvaged ultrafast schottky diodes and caps...

I repaired this digital voltmeter/ammeter that I ordered from shoppee that got damaged in transit... well that's what the seller said.

time to fire up my new (or is it old) "scrap constant current power suppply"

Electroplating naman...

Chemical reaction!

Testing on a Luger brass shell casing...

Testing the process on a badly oxidized sample. Before (left) and after (right).

Sir Jojo, YGPM po.

tony · « **Reply #12322 on:** Mar 08, 2018 at 07:15 AM »

Jojo, i have several of those tarnished rca jacks. if you want those. i can give them to Lingling at golden mars and you can pick them up there....

JojoD818 · « **Reply #12323 on:** Mar 08, 2018 at 05:58 PM »

Tony, sige good practice piece yan for my plating system. Actually naubos ko na pwede ko plate dito.

I won't be dropping by anytime soon though, may small house project lang ako ginagawa.

Thanks

tony · « **Reply #12324 on:** Mar 08, 2018 at 06:46 PM »

i think it is better to copper plate the brass before gold plating, or is it tin?

JojoD818 · « **Reply #12325 on:** Mar 09, 2018 at 07:59 PM »

It depends on the base metal, some requires copper plating first while other metals do not. It can be good practice though to copper plate first regardless of the base metal. I plate it in pure nickel not tin.

I'm going to start my gold plating setup but it's hard to find sources of chemicals (cyanide, etc), most acids requires special permits from PDEA too.
