  1. FINALLY cast my first project today. This is a new handle to replace the broken one on my wife's grooming dryer, this one shouldn't break. Casting went well for my first time and I learned a lot. Need more draft on my model part so the sand does not tear up when I remove it for example. The greensand was more work to prepare than I anticipated and I read you should do 70/30 sand to bentonite mix and i found that was way too much bentonite. Also I need to pack the sand into the sides of the mold better for a better surface finish, but the casting turned out with very little porosity. Cheer
  2. Aluminum and brass. I made some flasks from 3/4" plywood and I have some sandblasting slag and powdered bentonite I was gonna make green sand out of. Now I just need to figure out a good first project. Thanks
  3. Hey everyone Finished this new foundry and tools last weekend. Refractory has been drying for 3 weeks so I did a cook out firing for about 2 hrs on lowest flame I could sustain until it stopped steaming. Seemed to go well i didn't get any spawling really. I used 2 types of castable refractory because I ran out on the bottom section and didn't have enough for the lid, they both seem to hold up well.I can't remember what types they were, they were industrial surplus from a job at work partial bags that they throw away. I welded several refractory anchors inside the tank, seems to hold up we
  4. Jackstands now finished before paint. Probably try them out today on the truck to put a grease nipple in the slip yolk on my rear driveshaft.
  5. Dont know if you figured this out but my guess is you are cooking the flux off and the surface is oxidizing before you apply the solder. It is hard not to do this with a cooler torch like a mapp torch especially with a butt joint. Most solder joints are lapped like previously stated. This is easier with a cooler torch because the capillary action sucks the flux into the joint where it is not burned off as easily. With a hotter torch with a carbonizing flame such as a presto lite acetylene torch this is not as much of a problem and open joints can be brazed. A turbo torch with mapp also works a
  6. Yea I think I will bead blast them at work and prime and paint the bases. The sliding top section will have to be just bare metal and polished up otherwise i think they will bind because the 1 1/2" pipe in the 2 " is a pretty tight fit. The pins will be 1/2" grade 8 bolts. I might try to mill a ball detent with a set screw into the bolt pins but I'll see how that works out. The sheer strength of a 1/2" gr 8 bolt on a tight fit like that should be quite a bit, actually probably stronger than the legs. Anyways. thanks guys.
  7. I like it. Take an extremely overcomplicated project and make it more complicated. But I think the new switch will now outlast the rest of the plastic parts on the machine.
  8. Hey Made these tall jackstands the other day for working on cars. They are not quite done yet but the bases are complete. I made a couple jigs so they all turned out the same and I'm pretty happy with how they turned out. They are made out of sch 80 seamless pipe some 1"×1/4" flatbar and 3/16" plate. Finished they will be adjustable from 15" to 22". Let me know what you think.
  9. Hey everyone I got a small lathe and a mill last winter and have been quite busy with other obligations so I haven't really been able to use It that much. I have made a couple simple projects since I've had it just some shop chores but this is the first somewhat complicated project I have made. I thought it was pretty cool. This is the milk selector switch off of my wife's expresso machine. It broke about a year ago and I tried to glue it with epoxy a couple of times but it broke as soon as I put it on. So 4000$ worth of machine tools and 6 hrs of shop time later we have a sweet billit alumi
  10. Hello everyone Haven't posted in a while but this is a project I finished earlier this winter. I forged this knife this spring while I was making a knife for my dad's 70th birthday, I had abandoned it because it had formed a crack up the inside of the spine by the front finger groove. So it sat on my workbench for the summer until about December, when I decided to have another go at it. I managed to grind the crack out without taking too much of the handle material out. I had to take out about 3/4" of length out of the blade and about a 1/4" out of the width of the front of the handle. Actua
  11. Not sure what brand they were. They were left overs from a boiler repair at work.
  12. He liked it. It definitely made for a good conversation piece at the party. And i hope he uses it.
  13. My forge is made of insulated fire brick and I just friction fit it together. It is held together tight by putting angle iron on the 4 edges and then I have pallet banding ratcheted down in 4 spots. Only down side is you need a pallet bander. But it seems to work good and has held up for about 5 years so far. I have a piece of hard fire brick In the bottom that I change out every once in a while to stop the flux from eating the bottom too much. You can kind of see the idea in this picture. HERE IS A BETTER PIC
