Big Ray Posted October 21, 2014 Report Share Posted October 21, 2014 I bought some c-clamps a week ago from home depot and they work pretty good I am just wondering if I can damage my mold using them. Quote Link to comment Share on other sites More sharing options...

CNC Molds N Stuff Posted October 22, 2014 Report Share Posted October 22, 2014 C-Clamps work fine, but I have found I like the short cheap screw type bar clamps from Horrible Fright. I have a dozen of them hanging over my pouring bench. http://www.harborfreight.com/6-inch-bar-clamp-96210.html I take the plastic protectors off, and save them in a work bench drawer for when I use them for other things. I also have other stuff I have tried to varying degrees of success from home made vises to bench mounted wood workers vises. Quote Link to comment Share on other sites More sharing options...
Big Ray Posted October 22, 2014 Author Report Share Posted October 22, 2014 (edited) Horrible Fright lol! That is funny that you mention those clamps because I was going to buy them. The first clamps I bought where from Harbor Freight. http://www.harborfreight.com/4-in-ratchet-bar-clampspreader-62242.html They sucked because I couldn't squeeze them down hard enough so when I injected my mold plastic oozed out the sides. The cool thing was I took them back the next day and they gave me my money back and I saw the clamps you use Bob. I was going to get them but then I thought they might suck too because they are from Harbor freight. So instead I bought these clamps from Home Depot. http://www.homedepot.com/p/Husky-3-in-Drop-Forged-C-Clamp-97891/205132116 I think I might just buy the Harbor Freight clamps anyway because they are cheap and I see that they will let me clamp more molds together.

gone2long Posted October 22, 2014 Report Share Posted October 22, 2014 In short no, but in the long yes, if your mold is not aligned properly, if it is over-heated or a bur was present then yes you could have a problem, it's all about moderation, your understanding of too tight may not be the same for others, crank a clamp down on a mold that may be thin in a certain area well then you get the picture!
