Vulcanized materials are not that much cheaper than the RTV’s
especially if you are compairing prices to some of the new
vulcanized silicons. There is no additional equipment needed (the
vulcanizer) either. I just like the RTV’s as they , at least for
me, are so much easier and seemilgly, for me again, foolproof.
John and others who might know:
I thought that the vulcanized compounds were used because in a
production situation they keep the costs down — aren’t the RTV
compounds consdierably more expensive??
I find that the RTV materials cut easier than the vulcanized
molds. There are numerous hardnesses available in the RTV’s, more
than in the vulcanized.
I don’t cut molds yet, but those who do tell me that they change
blades after every mold or two. A box of blades isn’t that
Yep, blades are 10 15 cents each and at that price well worth
saving one’s finger. Don’t forget to lubricate the blades, huge
difference (be careful if you are not used to lubricated blades,
you might cut yourself.)
I couldn’t believe it when someone wrote they didn’t cut molds
because they might cut their finger — first, you’re a craftsman
(or craftsmann) you should be able to manage and ashamed to admit
it if you can’t. Second, when you learned to peal potatoes, didn’t
your mother tell you to cut AWAY from your hand??
Sometimes you can’t always cut away from yourself when cutting
molds but just being very careful and very aware of where the blade
is going to go if it slips or cuts through will eliminate most
problems. I will say a potatoe peeler is nothing like a sergical
knife when it comes to cutting oneself.
