Another cutting machine - “monkey”
Having taken up turning in my garage, I was tired of cutting round timber into blanks with a grinder, due to the lack of extra money I had to build this device, please do not throw rotten tomatoes about the quality of the photos - I only have a mobile phone.
stand for long workpieces:
Now the manufacturing itself.
The spindle body is welded, two already drilled pieces of round timber and between them an ordinary water pipe, outer diameter 90mm. The fastening platform, pre-cut along one plane, is immediately welded (on a lathe):
After welding and cleaning, I threw it into a potbelly stove where it warmed up and cooled down gradually - the effect of such heat treatment was nothing but because the welding was quite easy to process. then he healed for the outside and sharpened one side (the seat for the bearing, etc.), it was not possible to sharpen in one setting, so he took a long, hastily welded cutter and sharpened the second side “clean as clean” on which it was then set to a couple of hundred square meters...
the shaft (45 steel) and the entire spindle assembly, everything is assembled on two tapered bearings (from a Moskvich car), but it’s second-hand, but for such a thing we went all the way.
Making grooves for the engine for tensioning belts, still on a lathe:
I thought for a long time about what to make the handle out of and so that it would be plastic and reliable, and that the switch from the electrical equipment would somehow be secured in it, but as luck would have it, all switches of this type come without any fastening at all, so I had to take two cans of epoxy and a piece of half-inch pipe (a cavity for the wire and fastening the handle itself) and a couple of old keys for deadbolt locks (for reinforcement), and fiberglass. And start modeling plasticine 
— I forgot to take photos of the cast product :unknw: but it turned out quite reliably.
Then it seems like this:
Lego constructor - try to assemble:
I had to buy the engine on the market, I got an American one for 2 thousand rubles. as it turned out, it was not used at all (the branded wires were only stripped, but there were no connections), 2KW 2800rpm. connected directly with two belts.
The spindle is filled with regular machine oil, there are two oil seals with additional boots - no leaks yet
did not have. All the protection was welded by me, some semi-automatically, some by conventional welding (all load-bearing elements were welded with electrodes), the metal thickness is 2mm. I’ll throw in a couple of sizes: from the spindle axis to the swing axis -230mm, from the table to the swing axis 200mm.
Total cost for everything:
2000 engine
200 oil seals
200 belts (it would have been 100 if I hadn’t made a mistake in the calculations and bought the right belts right away)
200 button
200 epoxy
150 paint, solvents
Total 2950 rubles, well, I didn’t count the light and metal - it’s so vague, but in principle it’s a penny. Taking into account the fact that this type of cutting costs 30-40 thousand rubles, I consider it a penny...
That's all, if you ask anything.
