I thought Id start a topic for all to show there ingenuity here.
Building a gasifier can be quite challenging with out the proper equipment. Those that are capable of building these devises may also be able to build the machinery required to build more complex machines. So I thought Id create a place to show this stuff off.
When I started I had a cheap 200 dollar welder, and a grinder. I built quite a few machines out of existing tanks and parts. Mainly the portable air tanks you can get at Tractor Supply and Harbor Freight. These were the cheapest tanks I could find at the time and I could get them brand new. So prepping them for welding wasn’t to difficult. As I learned more and built more machines the builds started getting more and more complex. Along with this was need for the equipment to build these machines. They do not give this equipment away, and at least for me most of it is out of reach of my budget or I just simply refuse to pay the high price.
I have built quite few different devices in my shop that are used on a daily basis. One is the small roller I built, I built this roller about a year ago and it has been used just about every day since. We roll all of our cones and cans with it with the exception of larger cans like the hoppers. Now that the machines are getting bigger other parts are needed and outsourcing this is putting a strain on our production.
So I have built a 48" rolling machine. I will have pics of this machine soon, however, I am reworking it a bit. I have built the rollers out of 1 1/2" black iron pipe. Im using a set of gears that have a 2" pitch diameter. This combo is almost perfect for the 14 and 16 ga steel we use. This machine also has gear reduction. But I ran into some issues with my rollers deflecting, I was afraid this was going to happen, but I wanted to give it a shot with out reinforcing the roller. So I now have this machine back apart and will be installing a core inside each roller to eliminate the deflection. I had to do the same thing with my smaller roller, so Ill get it worked out.
Another machine that we have desperately been in need of is a large shear. I’ve looked around and I just cant find a 60" or larger machine that fits my 300 dollar budget. LOL We have outsourced our rough shearing and this adds to our cost. We have a small shear to cut down the pieces to there final dimensions.
So I put together a CAD model and ordered the materials to build it myself. I have just a little more than 300 into this machine and I put 10 hrs labor into it today. It is just about complete. I still need to install the guides for the upper blade, install the cam actuator and build a table to align the sheet metal. For my blades I just got a stick of 1/2 x 4 CRS and will case harden it tomorrow. I wanted high carbon but it had to be ordered and i don’t have time. So I will order replacement steel later for the blades. The case hardening should hold up for a little while we may need to do some periodic sharpening. But if you build something like this you need tool steel for your blades and you will need to heat treat and quench the steel to harden it. But this is not rocket science look at a paper shear, this is really just one of those on steroids.
