You do awesome work Tony! Loved this thread! :)

Wow, Ken! That is awesome! Thanks! That is something I can actually make, I am pretty sure. All you guys are awesome! Thanks so much! :)

More good ideas! Thanks! :)

Thanks for all the great ideas! :)

Hey guys, I have this spinner hub, that is drilled and tapped already for a 1/4-28 crank. I would like to machine away about a 1/2" of the material on the inside, so that I can thread it onto the crankshaft and sit down flush against the propeller, and hiding the prop locknuts inside. I cannot...

If it is going inside a closed boat hull, you would want water cooling. That is the purpose of my conversion.

Look for a model boat flywheel for a CMB or OPS .90 nitro engine (15cc). Run your engine with a rich mixture to help keep the cylinder cool. You can also add a water jacket around the cylinder head, and use an electric pump to circulate cooling water. Do not try to reach peak rpm as you may...

And the rest of them:

I just happen to have saved his photos, so I hope Metal Butcher does not mind me posting them for you.

Thanks MB! :)

Metal Butcher, thanks for posting this. I liked your idea so much I made one for myself, only for the 3/16" size fittings.

Didn't know where else to put this question... Has anyone made this pump from the casting kit? Not the pre-machined parts kit, but the raw materials kit? As I have not yet made anything from a casting, I was wondering if there are any precautions I should know about when working with the cast...

Okay, thanks. I understand better now. :)

I'm glad this question came up. If we have the ability to turn metal on our lathes, why would we want to use a grinder instead? My bench grinder I use makes horrible grinding marks on metal when use it with the standard wheel. Even a new green wheel I bought still makes marks. I can get a...

Awesome, thanks! ;D

I recently tried a 3/8" roughing mill and was impressed. That 3/4" is the bomb! :D What is that cool light fixture you have on yours?

Distilled white vinegar is what I use, recommended to me by a model engineer loco builder. Guess what, it works great and is cheap! ;D

Goodness, gracious! I won't complain about the cost of lumber anymore! :o :o

Add me to the long, long list of 9x20 owners who have upgraded to a larger QCTP and have seen the light! I had my Harbor Freight QCTP kit in a box for years. Just never got around to installing it. Now that I have, I can feel as well as see the huge difference. I already had the 4-bolt...
