  Good choice of colour for the wax. If you'd got pink, Slim might be givin hisself French manicures!

"I've cut that stock three times, and it's still too short!"

And with wax, you can add a little back if you take too much off somewhere?   

cnr6400  Now you know what to do when that happens  Ha, ha, ha

the blue wax is faily hard, works nice on the mill but is still carvable with the correct tools,,

did some changes to the valve ends, should not need a sleave now,, lots of exterior shaping this weekend..

I don't think the aromatherapy is working

Anyone else notice a smell of potpourri from about 1992 in the forum today?    >aCHOO!< snif...

[tghs]

a little bit of carving and shaping,, these two parts might need a little more work but getting closer.. still have to add the "M" going to try to use a metal stamp in aluminum to make a mold.. still have to make the crosshead wax..   (Slim has the holiday weekend off)

[crueby]

After all this work on the wax, am I right that you only get one chance to mould from it?

[tghs]

one chance!!! but learning stuff all the way..

busy week with that work crap.. but did get the propane tank to test fired the furnace to check for operation, also to thermal cycle a bigger crucible.. the burn-out kiln was run with the break-in program, glad I set it up outside as they were very correct in saying it will smoke during the first run.. shooting to do a casting run next week.. Slim stayed well away saying that he likes his shape just fine.

[crueby]

Glad the test run went fine, and that you didn't  turn Slim into a puddle!

When you're burning wax, or anything else, out of the investment it will smoke every time you do that won't it?  You'll be burning the pattern material in a limited oxygen environment and that's going to make smoke/soot isn't it?  I've seen an exhaust hood over most of the burnout ovens I've seen.

this was the empty break-in burn, I do plan on smoke for the wax burn-outs (will do a steam-out to remove the bulk of the wax before the kiln) neat little tool today, a wax melt pen, think micro spot welding.. great for tacking small parts together..
