Up the stick

[graffian]

I have a set of Hemi rocker covers and girder forks to coat, so I extended the oven something like 15" to get them in[I have to admit I haven't measured any of this!]. The frame is done and the door is hung, just some ali paneling and insulation to do. I nearly forgot I have to block the gap above the door, I hadn't intended on using the original door as making hinges seemed a pain, but it's nice to look through the window and see the coating flowing, so I fitted the original door.
I now can't find the bit of ali I thought I had to panel it with. I am considering chopping the lathe splash shield up;-)

Does anyone know about insulation sheet, the makers are not very forth coming. I eventually got a reply from one of the companies and their PIR insulation isn't for use over 100ºC and the didn't suggest what was. If it's fire resistant isn't it going to be OK to 200ºC? or is just OK with cold fire. I spose I will have to test some. I don't want to use fibreglass unless I box it in.

Compressed Vermiculite boards will take very high temperatures (they are used to line wood-burning stove fireboxes). Not sure how thermally resistive they are though.

Google 'ceramic insulation blanket' - possibly a bit OTT as its good for temps upto 1200ºC but it appears to be whats used to insulate Aga's amongst other things.

slaved over a hot oven all day

Eventually finished the pregnant oven, it only took me 18 months!
My forks, the reason I needed to extend my oven, came off the bike in September 2011, so I figured I better put them back on soon.
Luckily someones oven just died, so I nicked the insulation and
case panels. The insulation and cover panels are just taped in place, the screws to attach the extensions framework, screw to existing threaded point's in the oven door jamb; so the insulation need's to be removed to get at the screws. The outside of the oven gets to about 60ºC, with the inside at 195ºC . An upright oven would be a lot easier, the forks have to be on a slide/bracket to get them in and out of the oven, then you have to be able to take them off the slidey bit when hot to hang up again for a second coat, if your double coating; it's would be far easier to have stuff hanging up. The forks were pretty pitted so I gave them 2 coats of zinc rich epoxy and hopefully I can sand them smooth for the top coat.

Top man. You finished that a bit on the quick side didn't you?

That looks smart. Nicely done.
