1K Workshop

The goal is to design a workshop soup-to-nuts, that can be built for 1K$. While the goal is 1k$, the approach is going to be working fully through an approach to see what the total would be as well as the convenience.

Tools

Unpowered Hand tools

• Hammer
• screwdriver ratchet bitdriver (like I have)
• wrench
• pliers
• box cutter
• measuring tape
• square
• clamps
• sand paper

Powered Hand Tools

• rotary tool
• circular saw
• hand drill
• impact driver
• orbital sander
• plunge router

Table/Bench Tools

• band saw
• table router
• belt sander
• drill press
• miter saw
• table saw
• jointer
• planer
• shopvac

And a work bench to work on and system to store everything

Motor

Almost all plans require a large motor. Pneumatic motors are built by Gast and Speedaire. For pneumatic it looks like 1hp is about 30Nm of torque.

The Gast 4AM-NRV-92 might work for hand tools. It's just about the right size(4" wide, 4" diameter, 1.1" shaft). Also about $150.

The Gast 6AM line of pneumatic motors provide 4HP and generally go for $150-200.

A large 3HP electric motor is going to be right around $200.

A large 5HP electric motor is about $350.

I did find the motor armature for a circular saw. Actually, looking for "120V Armature" turned up a lot, and they're pretty cheap. Now I just need to figure out what the stator looks like. It looks like this one matches the previous one. It's just called a "field". The set looks like they cost about $120 together, with a little poking around, I can probably find something workable in the $80 range.

So either way, it looks like something around $300 for power systems.

Another option is to use a plunge router as the powerhouse (at least for the smaller tools). They run anywhere from $90 to $220 (for what we're looking for).

Parts

• Hammer $6
• screwdriver + bit set $24
• wrench $5
• pliers set $12
• box cutter $8
• measuring tape $10
• square $9

Total: $74

Powered Hand Tools

• circular saw blade $15
• drill chuck $15
• router chuck $15

total $45

Table/Bench Tools

• band saw blade $10
• sanding belt $10
• jointer cutter head $50
• trash can (for shop vac) $30

total $100

grand total: $214

So between the must-haves and the power plant, it's almost at $500. The remaining $500 gets spent on wood, cement, screws, bearings and the various metal framing pieces.

Bootstrapping

One of the challenges is that

Stand Alone Compressor

• Air compressor $60 @ Harbor Freight

All hand tools run off the air compressor. All big tools run off an induction motor.

Constructed Compressor

• Tank $40
• Pump $70

Then we need a large electric motor to run the pump.

Deconstructed Compressor

There is a 3.5HP 10gal air compressor for about $150. I could get that and pull the motor out, converting it to a modular system.

However, I'm not sure how much I trust that considering the motor would be worth more than the whole thing (if it's actually a 3.5hp motor).
