Homemade Adjustable Hole Saw // + free Plans

Hey there, in this video I am going to show you how you can build an adjustable hole saw.
Materials you will need:
-steel flat bar 200x25x3mm
-1x m10x40 allen screw
-1x m10x25 allen screw
-1x m10x20 allen screw
-4x m10 self locking nuts
-1x m4x10 allen screw
-2x m3x10 allen screw
-1x 4,5mm hss drill
-1x old saw circular blade (works best with carbide teeth)
Tools you will need:
-angle grinder or hacksaw
-metal file and some sandpaper
-10mm / 3,3mm / 2,5mm / 4,5mm hss drill
-drill / drillpress
-ratchet or wrench and allen key
-m3 and m4 tap and tap wrench
-vernier calipers
-markers
-hammer
-center punch
-bench vise
-optional:
-bench grinder
for grinding the cutting tooth can be also done by using a file or angle grinder and making a flat spot on the 4,5mm hss drill (a file won't work)
-inclinometer
for aligning the bolt when drilling the 4,5mm hole
-countersink
for deburring the holes can also be done with a file or a bigger drill bit

Can I ask why you didn't make 2 cutting nuts? It would be balanced, and cut faster, no?

[@builds_from_scratch3491]

Hey there don't worry just ask :) The second screw with the 2 nuts on weighs the same as the screw with the cutter. The second screw is there as counterweight. It would probably cut faster if i added a second cutter instead but getting both equaly spaced from the center is really time consuming and tedious. But if you plan to make one on your own you can give it a try with 2 cutters instead of 1.
