Title: Exhaust Collet/Clamp advice
Post by: 10tenmen on September 21, 2019, 11:53:39 AM

Took the exhaust off to clean it and had the collets blasted due to lack of chrome lol, what’s the best high temperature paint to use for painting them.
Ive also sent the carbs off to Bergen in Holland for the full works so I’m not in a rush.

If you don't mind an alloy color paint finish, the Simoniz VHT paint looks great on them. Very hard wearing also due to oven curing. It's SIMVHT31D. Also, it doesn't cost much to have them re chromed but the rust usually starts showing quite quickly due to the original wrinkled nature of the collars.

Thanks Julie just the advice I wanted regarding curing is that warming them in the oven before or after thanks.

All depends on the paint you are using but with the Simoniz VHT, warm them bare on a very low heat for 10 mins and then apply 3 very thin coats about 20-30 mins apart to build up, stand the can in hot water before and between each coat as the paint goes on better. Air cure for a minimum of 24 hours before final curing in the oven. Start oven off low and gradually (over ½ hour) increase to 220°c and cook overall for 1.5 hours. It does give instructions on back of tin.

Fingers crossed a job for Monday carbs are going to be away for 4-5 weeks so plenty of time to fettle thanks Julie.

Haha, no, you should be ok with the pepperoni, but I'm not sure about a Hawaiian 😀😀😀 Joking aside, for those of you that use the wifes appliances for bike stuff, with the baking of parts just make sure you have all the windows / doors open. The smell goes away fairly quick but it is a real strong acrid smell that some wives just can't get their noses tuned into for some reason 🙄🙄🙄 Luckily our parts / engine casing oven is in the workshop, so Trig can cook to his hearts content without me whinging and whining 🤣🤣🤣

That’s why it’s getting done on Monday my good lady Dawn (also a nurse) is doing a bit of work so is away overnight, thanks all.

My original 10th anniversary t-shirt. If you look closely you can see the battery acid splash holes

Sorry for the thread hijack.

Cooked to perfection, though as Julie says it can get a bit smelly, I used VHT Engine enamel, and don't confuse fahrenheit with centigrade otherwise it goes yellow as I found out.

Wow, that oven is clean!  Spitfire, have you ever used it to cook food?

Strangely, that was my first thought too.

Well of course you have to have a clean oven, you wouldn't want to tarnish a good cylinder head would you? With regards to the needs of the inner man all one needs is:- Freezer/microwave/frying pan, or a good local pub.

I am a very lucky man, the kitchen and the oven were brand new at the time and I was allowed to use it for my engine parts, no problem.
Hopefully she will be just as obliging as soon I will be starting to paint F2 engine parts !

I just have my collector box warming up in the sun to try and get the down pipes to fit in as they are a little tight . Not that warm today only 21 degrees but it will be too hot to pick up in half an hour . So just thinking if I was trying to cure some paint it gets well over 100 degrees in my roof soon (Oz )
