Is it stronger to case the block vs using a round extrusion that is the same diameter? I am a novice and have no idea, I can get just about any shape in any size I want at a local store, cusious why the choice is to cast the block vs cust it off the end of a round bar? Your work is beautiful, at times I really want to learn to cast as well as you! -jeff

Good case made for cost. Does anyone know about strength?

Strength depends on the composition of the scrap used in the melt pot. If you use chunks of damaged wheels (cleaned & no powder coating) it's bound to be strong enough for most workshop castings.

I chose to cast, as the store is very far from my home. Thanks for commenting

Go price some aluminum in that diameter and you'll learn why he cast his own from scraps. It's hideously expensive if you can even find it in that short of a length.

When I'm not buying full stick for jobs I goto The Yard Store, they price aluminum at $2.5/lb down to $1.5/lb for cut offs. I looked at an online supplier that I have used once, 3 inches of 8" 6061 round was $58. About a year ago I purchased 3" of 6" round and 5" of 4" round, bill at the yard store was $60. (I was building a base for a ball turning attachment for my 14" Rockwell lathe) I think they sell online. Is that is more expensive than casting, considering the time of the guy working? Thanks for responding, can't learn anything in a vacuum..
