Welcome, glad to have you here. .

I added some shelves on one side of the molding shop, since the bound molds have to be places on a very flat surface after they set, else they will warp a tiny bit; just enough to cause a mold leak, if they don't stay perfectly flat for about 30 minutes after set time. .

Bound sand can be reused, but it has to be ground up, and then the resin burned out. I don't try to reuse my molds, but I have saved a lot of them, and am considering grinding them up and using them as resin-bound backing sand, and use new resin-bound sand as facing sand (I think a common...

These are typical molds I made for the green twin engine, made with the above mixer. .

I have seen some in this "hobby" invest heavily in some very expensive lathes, mills, and other machining equipment. I have a very modest Grizzly lathe, mill, and tooling, which I inherited, so no cost. I have put my hobby money into building a commercial-grade iron foundry, and while that has...

This is the used kitchen sand mixer I purchased, to mix foundry sand. .

Nice ! I feel the same way for those who over-ask. .

I like working with steel, since it is infinitely cutable/weldable/bendable. I fabricated most of my foundry tools, and if somthing does not work correctly, I just cut it off, fabricate something new, and weld it on. I use a lot of those thin disks, and I have seen photos of pieces of them...

Nice bike ! .

Welcome Jemin, glad to have you here. Pat J Edit: We have bikers here too ! .

I really like seeing engines come together and run well. I have had a number of false starts on engine builds, where things never came together, and the build failed. I have only succeeded with on engine (so far), and so I really appreciate those who make it look so easy. Great work, and a nice...

I moved my mixer info to this thread, so as not to crash this thread: https://www.homemodelenginemachinist.com/threads/a-commercial-foundry-sand-mixer.36431/#post-416917 .

As HMEL mentions about residual fine particle dust going into the shop, I intend to use a cyclone/shop vac in series, and then pipe the output of the shop vac out through the wall, at least when I am sandblasting. The super-fine particles are the ones you really don't want to breathe, and don't...

That is actually pretty good welding for thin-walled muffler pipe. .

I commercial kitchen mixer works with clean new sand, but may jam if used sand and potential slag is mixed in it. There is a crank to lift the blowl up and down. I fill it with the bowl up. Commercial kitchen mixers are not cheap. I bought a used one, and even then it was not cheap. If I had...

I know a lot of folks who mull/mix in batches, including myself. My mixer container is about the size of 1/2 of a propane tank. Batch mixing works well, and keeps the muller/mixer a manageable size. I am not sure if it is in the design, but some sort of safety mechanism is really neaded with a...

I found this video at the Indianaengineshow link. .

Can you post on this map where we pull in for unloading, and where we park for the event. Need details, since I am no spring chicken these days, and can't do it if there are obstacles. Thanks .
