Gonna end up with sawdust all over the floor. Good job.
The flexy tube with the blue tape is connected to a 5 gallon shop vac. This setup has reduced rogue sawdust by at least 80%. At first I didn't give a shit but then it was a big pain in the ass having everything covered in sawdust all the time - much gooder now.
I wired the radial saw on/off switch in parallel with a 2way outlet so I can run the saw / light / vacuum by plugging one cord into the wall.
I believe the next big evolutionary step with the radial saw is to add a variable frequency drive.
I'll increase the speed of the output spindle, put a drill chuck on it and use it as a router table.
Then I could add a tail stock and a rest, and have a built-in lathe.
I have a T shape router bit to add 1/4in tracks into the table top, then add 1/4 carriage bolts with wing nuts to install all the planned attachments.
Only real downside I can think of vs. buying all these individual tools is the setup time but shouldnt take more than 5 mins to switch up to the new task plus it has a tiny footprint compared to a complete wood shop so I think it's a pretty decent idea so long as the motor doesn't have a problem increasing it's speed.
$50 craigslist radial saw becomes $1000's worth of tools
Suggested Maximum Router Bit Speeds
Bit Diameter Maximum Speed
1" 24,000 RPM
1.25 to 2" 18,000 RPM
2.25 to 2.5" 16,000 RPM
3 to 3.5" 12,000 RPM
Circumference = pi X diameter
"Tangential" speed (in inches per minute) = circum X rpm
So:
1" circ. = 3.1415 * 1 = 3.1415 ---> 3.1415in * 18000rpm = 56547in/min or 4712.25 ft/min or 53.55 mph
2" circ. = 3.1415 * 2 = 6.2830 ---> 6.2830in * 18000rpm = 113094in/min or 9424.50 ft/min or 107.10 mph
3" circ. = 3.1415 * 3 = 9.4245 ---> 9.4245in * 18000rpm = 169641in/min or 14136.75 ft/min or 160.64 mph
So a saw motor spins at 3k RPM because at the edge of an 8in blade it's nearing 200mph, so i'll have to increase the saw motor speed by 8x to move a 1in router bit.
