cracks in the clear coat normally mean the part was under cured. recure the part and they should go away:(

[EHSRACING]

hey pappy what do you use for a oven this is what i built for now im going to upgrade hopefully pc is really cool stuff

[EHSRACING]

hey thanks for the info to i will try to cook them again

this might be stupid but what would happen if you took a heat gun to it while it was already mounted in some spots just curious

[Pappy]

you would probably scorch the powder. put the parts back in a cold oven and bring them back to cure temp that way. once the proper temp has been achieved ...time it out. remember its part temp thats critical not just oven temp.

[EHSRACING]

does it do much if you cook them to long

[Pappy]

the majority of the powders have 100% over bake so heating them too long usually isnt a problem...getting the part to hot is tho:p if you dont have a laser thermometer get one....it will prevent this and will allow you to learn how effieciant your oven is and correct problems before they arise.

[EHSRACING]

laser therm? where do i find them and how $ sounds like what i need thanks for your help man

[Woodsrider]

You can get a laser themometer from eastwood or columbia, or you can get with the local Snap-on tool rep in your area and get one. I got one from Snap-on for $99 it reads up to 500F that is plenty.

No offense but that oven looks like a firetrap, are you sure that thing is safe?

[EHSRACING]

no, its pretty fire proof lol i lined the hole outside in durarock which will pretty much take care of everything i was working on a small budget im going to make a nice oven pretty soon though. im not scared of a little fire anway just as lons as my parts dont burn up jk

what do you use as for the heating ? and how do you keep the temp between 350-400 degree range?

[Castor-426ex]

should have used mineral wool...its not that expensive and has a flame retention of about 1200 degrees i think

[EHSRACING]

mineral wool? never even heard of that is it pretty common i would definetly like to find something like that i checked a couple of places and no one had answers for me how to insulate it

and above is just a house oven that i built a box off of i could keep the temp at about 365 with the setup i have now but im going to make some changes

[Castor-426ex]

i think its the same insulation used in household ovens...call an insulation yard..or shop...if i can find it local here...you should be able to do the same
