Forge info questions?

While you are going Hmmmmmm, here is another thought to ponder -
Making the burners Blown and Controlled.
You might say this is a Hmmmmm-dinger of an idea.

Several chaps here have built my PID controlled forge setup. It adds about $100 to a forge, but allows precise temperature control for forging and for HT.

Here is a thread on it ( there are others):

I am still drawing up ( actually, I asked JT to re-do the drawings) a clean schematic of this design.

I am trying to finish the prototype of a newer version,too. I am taking Friday off, so i could grind about two dozen fillet and kitchen knives in CPM154....or work on the prototype..... Hmmmmmmmm.

I think the Inswool is 6lb. and the Durablanket is 8lb. Is the cost of the Inswool 3/4 of the cost of the Durablanket?

The two are basically the same material. More weight per inch insulates better.

Larry Zoeller's Plistex 900 is quite a bit cheaper than ITC-100. They do the same thing... glue the fibers in place so you don't breath them and reflect heat.

No, the Inswool we sell has a density of 8#/ft^3. I think many will agree, that it is higher quality than Durablanket.

Also, not to continue to disagree with you, but I have seen zero data to back up these claims about this plistix stuff....maybe it's out there, but I've certainly not seen it.

Darren,

Cliff didn't say where he was buying the Inswool but I took the "6#" he put up in post #4 to be 6 lb.

I got hits on DogPile running "PLISTIX 900". I've no idea how to read the data. It looks like it is made by an Illinois company called Plibrico Company... http://www.plibrico-usa.com/Products/MRP/Inj&ServiceMixes.htm

Thanks guys I guess maybe I should have come clean at the begining of this post but, I didn't want what I was saying to influence the advice I was getting here and I did get alot of good advice!
I recently got ahold of of some 6# inswool for a little of nothing. However I knew hardly anyone was using 6# so was wondering if it was a good deal or not to use it.
You know do you use the cheaper stuff and have to replace it three times in the time you would have to replace say Durablanket.
I looked up the specs on both and although I am not really qualified to understand that stuff. They both had almost the same basic indgredents and fairly close on the heat limits I still was unsure,and am still today am somewhat unsure as too the real differences. I figured it was more like brand names, and I think that is somewhat true but, the real difference may be the key indgredents.

Thus the questions about doubling up the material to make up the difference in density from 6# VS 8# and also I had been told that was the thing to do.
I tried contacting several of the manufactures and distributors of the inswool and the durablanket and not one of them has even bothered to return an email. I look at it this way the ones who did respond on this forum are the ones who actually are using the products and probably have almost as much knowledge if not more than alot of the people who are in the field by profession. See alot of them just sell the product and only know what the company brochure tells them if that much. The real knowlege lies with the people who have used their product and know wheter it lives up to the claims or not.
I am member of several other knife forums as I am sure some of the rest of your are because I see you on the other forums. However I have got to say, I think this forum may be the best of all of the forums bar none!!!!!!!!
I want to thank everyone and I do mean evryone that has answered my emails and posted on this subject. It is open discussions like this that clear up alot of misconceptions about forges!

Mike,

Thanks for posting that link. It confirms my suspicion. The temp rating is too low to contain the same materials as ITC. If you're looking for something to just stabilize the fibers, then Satanite or APG36 is much cheaper....

DixieBlades,

If you want technical details from the manufacturers, then you need to contact the engineering departments of those companies, you're correct, the salespeople are just going off of the data sheets, however, the engineers who work for those companies, know the stuff.

There aren't really that many misconceptions about forges out there, *if* you're using a reliable source. Most people don't want to use a reliable source, it takes a little work, you have to read books, journal articles, or model them in the appropriate software. Forges and furnace systems have been around and used in industry for a long time, we're not breaking any new ground here in what we do with them...these things have been designed and modeled for a long time.

Well said and thank you! In case you all didn't notice the key word in that statement it is *if* !!!!
