I know it's no use to the purists but that bronze colour looks fantastic, ideal on a special. What make did you use Julie, just so the rest of us can avoid it.

It's Dupli-colour Engine Enamel with Ceramic Resins Roy.
I like the colour too, on a Mongrel but if I were to tell the truth I would prefer that all my engine was all the same colour but it was a good bike to trial it on.
The Simoniz has a maximum heat range protection up to 800°c where the Dupli-colour only protects up to 288°c. But, its really designed for car engines, not air cooled motorcycles with cooling fins. We found that the fins actually get that hot on the bikes that the Dupli-colour chips off where the Simoniz VHT just stays on perfectly.

Well back to the main subject of this thread. If anyone wants to discuss the actual engine paints I am using just PM me and I will tell you my thoughts and why I chose what I did ..... but remember I am just a DIY amateur, in lock-down, using the best he can do to get on with some projects but at the same time, drawing on the experiences from other forums (particularly the CB750 Sandcastonly forum).
This mornings bake off challenge was my Oct 1969 CB750 crankcases ... the 'oven' was a tad too small but six bricks and 5 minutes later we are up and running again. So it's a truly 'modular' oven. Next up are my '67 Bomber cases (well the top one as the bottom half was never painted)
I was hoping that with this thread, rather than drifting off into a paint preference discussion, I would be have been challenged. "What about health and safety though Ash".
I must admit I work with electrics / electronics all of the time and my missus is always telling me I am too complacent .. and she is right to a large extent.
So please, please.... if you make one of these ovens, or similar with your own modifications.... be really careful. Here are a few tips but I would really appreciate others chipping in with do's and don'ts regarding safety.
1) Use a mains supply protected by an RCD earth leakage protection device. If your house electrics consumer unit doesn't have this feature .... then buy a plug in one from the likes of Screwfix... always best to own one anyway if you are using 240v mains power tools outside and they are fairly cheap nowadays.
2) Use an extension lead that is capable of carrying the full 13A of a domestic mains outlet and .. very important FULLY extend the cable otherwise if left coiled it will overheat on the reel ! A lot of cheapo extensions are only 10A maximum current rated, which is borderline for a 2.5kW load.
3) Fit the thermostat (and indicator if you choose to use one) in a suitable enclosure and if it's metal then connect the earth wire of the plug to it.
4) Connect an earth wire to any exposed metal.
5) Make sure the cooker element exposed terminals are covered with some heat resisting sleeving (usually glass woven or silicone ) If you can't find any PM me.
6) Make sure you stand the heating element well off the floor so that the connections are above the floor by at least 1".
7) Always use in dry weather or better still assemble everything in a garage (not an option for me as my garage is linked to my house and the fumes always find their way into the house).
8 ) Connect the element to outside of the oven with heat resisting cable (usually glass woven or silicone insulated) capable of carrying 13 A .. loads of places on eBay sell it cheap.. just Google 'oven cable'or 'heat resisting' cable. If in doubt PM me.
9) When inspecting the paintwork .. switch the mains off first at the mains outlet. Same when you are finished baking before taking the parts out.
10) Use the oven when kids and pets are not around (e.g. get up like a true baker at the crack of dawn).
11) If you have the storage space and remote location from the house, just buy an old kitchen oven secondhand for next to nothing and use that.

Chipping in:
Item 2 - it is really important to fully extend any cable that is under significant load. If you leave it coiled on the drum it will overheat and ultimately melt.
Trust me on this

Yes Ken, I had to force him in to submission to fit non standard bits to this bike, my 550 Mongrel. I was on a budget but he wasn't happy using non standard fixings and I haven't heard the last of it 😁😁😁😁.
