So much info. Still didn't absorb it all. Clearly an enhanced process. Like the recycled clay. The molten metal feeder/reservoir is interesting. <br /><br />You seem ready to cast a 52 inch prop. <br /><br />ThanksHachitahttps://www.blogger.com/profile/13817818554013988050noreply@blogger.comtag:blogger.com,1999:blog-6120586935905234915.post-72680005928211565352021-06-01T16:29:38.030-05:002021-06-01T16:29:38.030-05:00Wow,really cool process.

I was building a hot rod but as I was there every day for 8 hours I got to learn a bit about casting and mold making. One thing I thought of as I watched your video was how they did the tamping. They used an air-operated chisel with a special head.<br />Just before I finished my project (you get a lot done if you put in 40 hrs a week without stopping to BS and drink beer) we did a 52 inch 5 blade prop. The molding process for that was indeed a big deal, as you can imagine there were undercuts. Very difficult and pouring was also critical. A lot of bronze and timing was everything.<br />Nuff said.DELhttps://www.blogger.com/profile/15757102594753616769noreply@blogger.com
