Rough cast bits smoothed out.
« on: May 14, 2013, 11:14:35 PM »
Just thought some might like to see these parts that I've been working on for umpteen hours filing, sanding and a quick polish ready for chrome.
I always thought these parts the way Honda slapped em out with the rough cast all over the place and their dud white chrome were pretty crappy looking so before I get them chromed I figured I'd get them looking how they should have looked when they were put on the bikes.
I dunno if it's a common thing but I find that chrome places are pretty uncaring about the way they sand off bits so when you get them back the chrome may look great but they are out of shape, this has happened to me a few times so this time I'm making sure they don't touch them. Have a look at these and then check out how the stock parts look.
Maybe it's not a big deal to some but to me it's the detail that sets things apart. You'll also notice I put washers on the bolts, Honda doesn't think they are needed but without them the bolt will gouge into your part, if you want it to look good, I'm funny like that :P

Nic,
Why chrome?  Those parts look gorgeous as is!  :D

Nice job - I'm sure the finished pieces will be spectacular.

Thanks boys, Gman, they'll just rust if I leave em like that. I've done all the engine bolts and washers as well, I ground off the tops of the bolts to make em all smooth so I could polish em up, as well as that, they collect dirt n muck as they are stock. I'm not a chrome freak per se but I like to put a bit here n there, brfff, in saying that, I do have a chrome headlight shell and gauge surrounds as well as the chrome ears to go on so the head will be a bit chrome overkill. Can always put some black up there if it's too much.

Pretty nice Nic!  Are those parts aluminum or steel? I guess since they rust then they are steel or a ferrous alloy that is chromed.

Are you going to refinish your side stand and center stand and have them chromed?

Thanks RAF,yes mate, steel, lots of hard work getting them smooth. The center stand has been powder coated along with the frame, the PO had the frame done but left a few things still on the frame so it was sort of black washed if you will. This bike is lucky I came along I tell ya. The side stand I've wire wheeled the powder coat off and had a bloke "almost" straighten it using the oxy torch but geez if you want something done right you better damn well do it yourself. So I'm just gonna paint the side stand satin black. The spring is also coated black, I may try n wheel it off but may not get it all off, that stuff is hard to shift in some places. I'll need to find another dude that can straighten the side stand for real, or even bend it a tad the other way. The engine cases will be polished alloy, no chrome there.

I polished some aluminum parts recently for another forum member and the sore fingers from that on the aluminum caliper was intense. But they came out pretty nice.
 The dremel abrasive rubber bits (cones and cylinders) get the tight spots to remove the finish but it is hours to get all the nooks and crannies with buffs and felt bobs. I did the fork lowers but did not attempt to smooth the casting on the inside of the fork legs other than what 220-400 paper and the emery to white rouge would do.

I can imagine my experience was childs play compared to doing this to steel to the luster you have achieved. Good thing we do this as a hobby and aren't paying others to do it...

Yeah, I did my fork lowers not long ago, I didn't get too detailed on the inner side of them either. The steel bits, you actually get quicker at it once you get a system. I too used the dremel in the nooks but a cork sanding block and 280 paper cuts it back pretty well after the dremel or 280 wrapped around a Phillips screw driver shaft is good too. You just have to be patient. 280, 360, 600, 1200, 2000 paper and then polish. If you scrimp on the 280 n 360 you'll have scratches that won't come out. I wouldn't want to do it too often though. I've been polishing stuff for a couple of months now, nearly done, almost.

Polished up the cam chain tensioner and SS bolts n washers. You'd never believe how beat up this part was.
Got all my chrome back, it really does pay to sand and polish your bits so the chromer doesn't have to do it and really, that's what you pay the most for, it's a lot of work though but you save a bundle.

Here's the brake arm chromed. All those rough cast marks gone, this is how they should have looked stock I reckon, Honda's chrome is garbage, still is today on the OEM parts.

Those are beautiful! I love chrome, and always have (even during the Gold Plated 90s  8))
If I had your skills (and chrome shop), I'd be doing the brake rod and bar.

Shout it: "We shouldn't have to defend our shiny bits!" "Can't they look good and run well also?"  ;D

BTW, does your government have restrictions that make the chrome shops expensive to operate? I just found one in our local phone book that advertised "yes, we're still open!"

Thanks again beauty lovers. I have no idea what the mongrels make the chromers do here, all I know is I took a heap of bits in, mostly nuts, bolts and washers and a few bigger parts and it cost me $180, that's because I did all the work. I asked them how much to chrome my rims and they said $200 each so that shows you how you're paying for their labour, I wouldn't even think about doing the sanding on a rusty rim, of course you have to strip the chrome first then sand sand sand, $200's probably pretty fair. I just ordered new front and rear DIDs from Z1 enterprises, to my door for $300.
Just for the record, I'm not into chrome engine covers, they have to be polished IMO.
Brake rod n bar as requested  ;D

good work nic,yeah polished alloy looks best,,its a labour of love though for the rest of the time you own it,yeah if you can organise the de chrome then do your own prep with the chromer youll save much money,,they have to obey so many epa rules and regs etc which is also expensive,factory chrome is thin and hap hazard,with minimal hand prep.,youve done bloody well mate!all that elbow grease has paid off.

just out of interest we did a few bins for a chrome place that has to have its tanks de sludged,,all the crud gets ph treated  and certified etc by some company,,we did i think four three cubic metre bins for them and the process cost them 25,000!!that gets done every few years,our bins price at the time was about 150 bucks,,we were busy and didnt empty one of the bins straight away but sat it at our yard,,whoa,,after a day or two all this green copper sulphate looking ooze was coming out of the rain drain holes,those bins then rusted quickly after that.

Thanks Dave, I was gonna take a pic of all the nuts n bolts n washers when I got them home n they were still all wired up but I just couldn't wait to get all the wire off them, there were so many of them and every side of every hex nut and bolt was filed and then sanded before polishing then chromed. If you have a look at your average nut or bolt the stamping leaves then rough as guts on the hex sides, no one will ever notice but my nuts n bolts are all bloody pristine. It nearly did me in doing them all, it took me weeks and many sheets of paper and rubber gloves, it's messy sanding metal but man I'm glad it's done now. Even the washers, on the edges the stamping leaves them looking rough, I used spade bits and drilled into wood just deep enough so I could sand the top of the washers without them sliding all over the place, the edges I would run over the grinding wheel first, then holding them in my hand I would sand them with 280 then 600 then polish, as much as a PITA that it was it was nothing compared to doing all the hex sides. That's why I also ground off the tops of all the bolts so I could get them looking pristine, the purists will no doubt hate me :o

LOL, that and the kick starter were some of the few parts that had good chrome, the starter cover has a ding or two though.

Looks very nice.....I'll offer you room and board for your vacation on the Gold Coast.....

A mere 4 hrs of polishing a day on Aluminium is all it will take mate . :)

Thanks K, that would be good, I'm down south NSW and freezing these days. I couldn't possibly leave my project though, I'm close to having all the parts for it.
