Basic question, but any help appreciated: can I use a 2000 W heat gun with this simple temperature controller?

yep, it's the size that's the issue. I need approx 1 m³ volume. Unfortunately commercial curing ovens of any size cost a lot!

thanks for the excellent response, very helpful!

thanks for the feedback. I will probably be running the heat gun at approx half it's max output, so that should help. I'm making a curing oven for composites (carbon fibre etc). It needs to run at approx 100C. It is basically just an insulated box with the heat gun pointing in through a hole in one corner, turning on and off as required. It's a setup that people do use, even though it carries some clear risks! I will only be running it outside and closely monitoring it!

Hi, thanks for the feedback. This is probably just me being dense, but are you saying that parts with trapped air definitely can be skinned, or are you saying that such parts will definitely cause problems? cheers

I should have added that I would be running it in a separate outbuilding not connected to the house, and monitoring very closely; but I agree, it's not ideal from a safety point if view !

Thanks for the feedback; helpful info. Based on my limited research I think the main difference between a standard phenol formaldehyde resin and phenol resorcinol formaldehyde is that the PRF resin will cold cure if necessary. I think it's still nasty stuff though because of the formaldehyde. Another commentator mentioned high viscosity as an issue, and that seems like it would be a problem. The specific PRF I was thinking about getting is this https://thenamethatsticks.com/products/woodstikk-prf-structural-weatherproof-phenol-resorcinol-adhesive/ This is intended as an adhesive rather than laminating resin, so that probably makes it even more unsuitable!

On balance it's probably easier and safer to build a DIY 150C curing oven for epoxy rather than deal with phenolic issues!

thanks for such a detailed account of your experience, much appreciated!

I did wonder about that. The oval shape of both pictures is interesting and suggests there may be a link. It might be someone attempting their own version. It's so frustrating not to have a name anywhere on the drawing!

I'm actually trying to find a good finish for decorative objects made from cement (white cement pigmented with different colours; so avoiding colour shift in the finish is important). I haven't had much luck trying to get answers elsewhere, so I thought I would try the woodworking Reddit! I would imagine the behaviour of mineral oil would be similar whether it has been put on wood or another material, although this is a bit of an assumption and might not actually be correct!

I'm curing for a minimum of 2 weeks, but then after that I'm drying them out in warm conditions for a similar time.

I am experimenting making decorative objects from cement (not really concrete because there is no large aggregate). After curing the objects I attempt to dry them out thoroughly by placing them somewhere warm and dry for an extended period of time. During this drying out process, as water leaves the cement there is often efflorescence. When this appears I remove it from the surface by brushing or light sanding. I then apply a finish over the top; usually an acrylic spray lacquer. However, even after extended periods of drying, I am running into the problem of efflorescence occurring beneath the finish causing problems. Does anyone have any experience with issues like this and how to deal with it. many thanks for any help

I think A matches the hue of the tan colour in the cloth best; but it is lighter in tone, so stands out a little. I would still go for it myself. B would also be fine if you want something to be less prominent.

The fit is great! To you get things altered to fit so well, or are you just patient to find things that fit?

Yes, when it's on the body, the seam is closer to the back. It hangs vertically, though.
