Well the plenum i bought form here arrived today, So i decided to start the polishing process strait away, Have also informed the boss that im skipping work tomorrow because i have "Important matters to attend to" lol. Anyway, Tools to be used wil be sander, using the typical process of going from the roughest grit down to the finest grit, i also have a grinder + disk that i was going to start the process off with but i dont think its necessary. What i had to start with. After 15 mins on one of the runners. More Fun Tommorow.
I'd highly recommend grinding off any casting marks BEFORE you start to polish as they will look terrible with the rest all shiney. And if you grind them off once you've gotten the rest nice and smooth you've got a whole heap more work to do.
post piccys as you go,it will be interesting to see the progress,remember,with metal polishing,patience is a virgin or is that virtue i cant find virgins,so i take the slack way out and buy polished stuff already done (stop quoting pictures ev you nooooob lol )
If someone sold one to me ide probably have bought it anyway lol. But i thought this could fill up those boring afternoons on sunday / saturday for me. Yup will do it all properly starting tommorow. I can easily see how this job can take over 50 hours now, especially if you want to get into every single little crack and crevice. I want to get alot of it done as i dont have a throttle cable cover nor do i want one, so i cant skimp out on the middle. will post lots of progress pics.
find a mate with a mechanics workshop and get it bead blasted first. Will easily access all of the galleries and give you a much cleaner working surface to start with, saving you additional clogging of your sandpaper. Put mine on the other day, combined with polished cam covers. Makes a world of difference
ps- DONT get over excited and hit it with too coarse grade sandpaper. The 1 I got polished came from another member who had started polishing. Even after returned, was left with waves in the top from too much aggressive sanding
i wish you luck, i tryed at one stage but gave up after about 2 days and pawned it off half polished lol
Looks like Niall left his half polished too...You gotta do the front sides of the runners too or it looks like crap when its installed.
I spent 4 bloody 8 hour days on mine looked pretty much like rollins then I left it on the na engine sitting out side and it has tarnashed pretty bad after a fe months
i bought mine 100$ with throttle bodies unpolished... price for polished? well it all depends on how much you want to pay, if no one is looking for one the you wont even get 100 bux for it. i wouldn't pay more then 200$ for a polished plenum though.
