Is it good enough to cut huge blocks of wood or say flat wood for framing? If you were wondering I used to use a normal handsaw but it takes a long time. So I just want something which helps me do that faster without breaking the bank. I plan to either borrow or buy a used one locally. But angle grinder and drill will be new.
Another tool which I'm looking to buy is welding machine but once again I don't know anything about it. Just that I've seen people work with them. The welding machine will be for moderate home use. Not like those heavy iron and steel workshops.
Plywood is tricky to get perfect cuts, I did work around it by being careful and using other straight plywood as guide, but one small error will make a big error.
For cutting wood blocks like 2"x4" no issues. Only when cutting plywood,MDF etc. When I was making a battery box, for the frame I used hand saw because I wanted a 2mm accuracy.
Some carpenters have even made a wide base stand using a 6mm plywood/MDF and they cut as good as circular saw, minus the safety stuff of the circular saw.
If its just to cut some one time use, just rent the saw. When I was making the battery box, a carpenter asked 200 bucks to cut the 8x4 feet marine plywood evenly into 4 pieces, while I cut the remaining 2 sides of a left over plywood myself with a marble cutter, for 40 inch I cut mm straight, I paused for a few second at the 40inch mark and resumed again but the rest 8 inch was off by 3mm basically the width of the blade. Why did I pause because I couldn't see the line I had drawn with all the saw dust vs the blade. Where as dedicated circular saw will have mark on the base to show where the blade is.
Welding, there are so many cheap chinese ones these days, but you have to get a DC machine. I have a Esab MMA./scratch start(stick) DC inverter welding machine paid about 25k or so in 2011. While my welding skills are piss poor, a welder used my machine to run for a week of work for me and even in the summer heat direct sunlight it held up quite well, I off course on my part used a small table top 8inch fan, to cool it.
If you want cleanest welds, a TIG welder, with a welding Gas port will do really nice job( American choppers OCC use that), TIG can also weld aluminum.
Then there is the MIG weld, which is the easiest novice friendly machine, it uses a small wire and as you pull the trigger it feeds the welding wire, they sell mig machines with a external or separate wire feeding machine, which makes the cost very expensive. Some high end ones come with built in wire feeder. But they can also be used like regular MMA/scratch start without the wire feeder.
