But, i need help… has to do with composites… some what
i need heat!!!
its getting to damn cold! little heaters arent working. i need something to leave on almost all the time. i dont care about the bill. but i care about 2 things
safety!
and life term
i need something that will heat well. not use gas, only electric. will fill a space something the size, 30ft by 45 ft. if i need 2 units. fine. something in the res. price range. not 10k! 50k btu’s maybe!?
i need it fast, and now! buurrrr
Try looking up MacMaster Carr or Grainger’s but not cheap! The time to buy them is during the summer like now is the time to but summer air conditioners.
I have a 3’ tall round propane heater (from Home Depot, go Tony!) for my fab work area but the wife steals it for her swing set “hang out” area…
I did buy 2x 1’ x 2’ (?) electric heaters from my school dist. auction cheap but shipping them to you…?
I’m told some new construction bldg’s plumb water pipes under / into the cement flooring for heating and cooling?
i was looking at some 32k btu units. 289$?
sorry, 17k btu

what do you guys think?
My used heaters that I bought from our school auction are very simular ones. I never hooked them up but I paid maybe $10 each for them. Yours for that plus shipping but no warrenty…?
What really made me sick, the school was closing out a metal, welding and machining class when I started teaching and I wanted to bid on the whole room (Mills, lathes, tube becnders, arc, mig and tig welders and tons of supplies…) I was told I could as conflict of interest. It all sold for $2000 only! :mad: Then they tell me, “Oh, you own your own business, you could have bid on it…”!:mad::mad:
LATHE!? MILL??? holy darn… you should of killed the person who bid lol. 2nd bidder always wins 
j/k
pm me some info on the heaters please. name, watts etc. thanks!
…make that multiple lathes, mills, gas and all types of welders too! You name it and all for $2000. The moving costs of all this equipment would have more than that but that is how school do these things now a days. I have heard they are auction now on ebay instead but…?
I’ll dig them out check on them and take pictures of them…more costs if I have to hook them up and test them…time is money…if they didn’t work, they woud have tossed them and not auction them off. But?
man…why do I never hear about those auctions…I would have transported all that crap for a whole machine shop at 2000 bucks.
I feel you on the winter crap. Ive been using propane to heat the area designated for composites…and I built a cure oven by using 500watt halogens in a wooden box. Relatively safe and I see 150 temps on my parts in the box after 10 minutes.
You have to be on each school dist. auction list (the old boy network)…top secret unless you know someone…now I’m on it but the rumor now is a company comes in and takes pictures and does it online like at eBay…but yet another top sceret!:rolleyes:
You can always use a propane heater to get the room up to working temps and then work. But use an electric heater after that.
More dirty school secrets are going to be coming out but I still want to sub until I get out of Calif…:rolleyes:
hmm. well let me ask you this. all the resin and equip that people have in shops. if it goes below normal temps when the heat is not on, (at night) and then when your in the shop and heat is on and working temp. is this distroying the resins, etc???

I can’t see it destroying the resins since they are rather inert unless mixed, not only that but lower temps result in slower chemical reactions of any sort, one thing that is very possible is that the temp changes result in condensation which could be crappy.
so long as the resins didnt freeze I cant see why it would matter and I dont even know if resin can freeze…
And if youre doing your layup and you get it B staged…it will just cure a bit more slowly but the heat from the process should carry it through.
Ive just noticed that it takes longer in the mold so you dont see shrinkage…
perfect. all i wanted to know =)
I looked in the container at the classroom, but it is really full of this VW Bug body (full size) molds and other stuff. :rolleyes: But I’ll keep looking for those heaters.
Actually, you can extend the shelf life of resins and stick tapes by refrigeration or better yet freezing them!
ok =
what do you guys think of diesel heaters!? had a friend bring his over. kinda scary. but worked! 60k btu!? fan runs great. but kinda want it to be hung in the ceiling.
hey keep looking =) pm me when u do find it. thanks a lot man!
