Rob, I want to thank you for the videos you have been putting out every day. It has been something I look forward during these times of uncertainty. It is refreshing to see something other than the depressing stuff coming through every other media outlet. Thank you Sir! I have learned alot.
What kind of sorcery is this? Just tried this and this may be the single most helpful thing I've found on YT in a long while. My bandsaw has gear reduction, so it's always been able to cut metal with the right blade, but thin sections are tricky as even with fine teeth, they tend to want to "grab" the teeth, especially if the metal is thin and tough (think thin stainless). This method gets around all of those issues and for you folks who only have high-speed wood-cutting bandsaws, this may be just the ticket! Thanks Rob!
That’s pretty crazy Rob, never would’ve believed it !
Rob,
Thank you for an excellent set of videos on the bandsaw. I was having a bad time of ripping and after your tune up it is like a different saw. Most instructions I have found are very vague and most videos i have watched show how good someone is using the saw but none get into detail like you do and really share the good stuff. Thanks again for a great set of learning tools.
Thanks for the excellent bandsaw series! I bought a bandsaw a few years ago and never used it. I went to set it up yesterday, and both tires split at the seams and fell off. :-) Ordered a new set. After watching you use yours, I'm looking forward to getting mine going.
Good series Rob. Sure do appreciate you taking the time!
What a great way to reuse something you would've thought it was trash but turned into a new tool to use!
Thanks very much for this series. I am in the market for my first bandsaw so this has been invaluable. Never mind the distraction from working from home. Keep up the good work and stay safe. Cheers Greg from Sydney
Thank you Rob. I dulled up a blade a month ago resawing a co-worker's supply of wormy chestnut by hitting some hidden nails I did not find, so now it will be my metal cutter.
My favorite tool, the Crescent-Hammer. Just a little jab. I know about that tool because I use it enough that my Dad is probably turning over in his grave. I used to intentionally fold maps incorrectly where he could see it, just to drive him crazy. The real truth is that I think I can trust what you tell me in these videos and know you have experience to back up anything you say. That is more important than anything else. Thanks so much.
Thanks Rob ; ALWAYS informative!!
I can see it now Episode IIV.. Jake fusion welds with a wood lathe..great show guys!!
Wow, great tip~! I don't cut a lot of metal, but I'll definitely be saving any bandsaw blades for this purpose, should the need arise. Thanks Rob~!
Thank you again for this very informative video. I really appreciate all you are doing for us.
I like it. These videos are a good supplement to being cooped up. Thanks.
Great Tip Rob. Thank you for sharing. 👏🏻👏🏻👏🏻👏🏻
If I wouldn't have seen it I would not have believed it very cool Thanks Rob C
Thanks for the videos there both informative and entertaining and a great diversion for the times
Awesome series. Thank you.
Fantastic, Thank You!
Amazing never seen that before! 👍
Cool idea. I wonder if it will carry over to other tools, such as jig saws or similar.
Thanks for sharing!
@Brett Itchkow I think you'll find that you still have a thrust bearing (with a slot in it to fit the blade).
love the videos!!!!!! table saw series next? im dying to see your other table saw on the other end of the shop
If I hadn’t seen it I would not have believed it and I don’t live in Missouri. Great video. Oh! By the way the people that make adjustable wrenchs also make hammers. 7:14😂
Mind blown...
what a great idea, thanks.
I never dreamed that could be done
Thanks Rob. I'd be concerned about getting metal chips embedded in the tyre (or is it tire?).
Nice finale! What's up your sleeve next?
Tomorrow we are working on the lathe, how to use a skew chisel.
OK, I'm going to cut the teeth of all my band saw blades now.
What about a blade with many tpi and it's dull. do you still have to file them off? I've been told by others that a fine tooth blade was o k for metal. Dan
Could you guys do a video or series restoring an old tool
How did you find this out?
Amazing, 👍
Someone showed it to me long ago and I’m sorry I can’t give credit to them since I can’t remember!
By the way Rob, Woodcraft sells bandsaw wheel brushes for $10.
Really interesting. Let me parade my ignorance, how on earth does this work?
friction, contact with the blade is spread over the 157 inches of blade working on the small area of the piece being cut. burns through it.
@@RobCosmanWoodworking Thanks. It was going to become a brain worm if I didn't find out.
I have a old general 191. Do you know if they came with a theist bearing? Mine doesn’t have one. I’m thinking it did.
What the heck!? How is that even possible? We go into a minimum four week lock down in six hours from now, so it's going to be a while till I can try that, but I can't make myself believe it. I just had a thought and looked at the date, but it's another six days until April 1st.
Couldn’t you turn the blade around backwards since it’s already flat?
Then the teeth would be chewing up your guides and your thrust bearing!
And most blades are bimetal, so you have tool steel on the teeth side for cutting strength and mild steel away from the teeth for toughness (less brittle). Mild steel won't get you very far doing anything to metal.
Rob, where do you find your older tolls like general and Rockwell delta besides craigslist?
Meyer Made Leather Co. government surplus, usually military bases.
Really good tip.& to hell with the message critics that break stones about every little thing they can pick out (i.e.gloves,ect) guys work hard putting great videos&instructional content&these parasites miss it because there too busy critiquing it.
Sorry.just sick of everyone jumping thru hoops to try&appease the unappeasable.
ROB, DOES THIS HAVE TO BE A CERTAIN TYPE OF STEEL BLADE, OR WILL AN OLSEN & OTHER CHEAPER BLADES WORK JUST AS WELL?
i have done it with several blades and all worked.
Very cool and very counter intuitive...Thanks again Rob and Jake. This series is fun to watch. Trust it works for your business as well.
thanks Howard, March will be a record month, we are going straight out. Thank you folks!
Jim Cummins, RIP, showed using a dull blade to "friction cut" metal. He didn't grind the teeth off, so your cuts are probably much cleaner.
What is that on the handle of your screw driver?
We tape everything with hockey stick tape, improves grip for we older folk! robcosman.com/collections/miscellaneous/products/hockey-tape
what is the blade speed?
How come that works? Please explain.
Magic! :), burns through, friction. Contact on the piece being cut is concentrated but spread out over the entire blade.
An experienced woodworker told me that you can cut metal by turning a bandsaw blade inside out so that the teeth are facing up. I haven't tried it but he said that it makes beautifully smooth cuts in any non-ferrous metal. Anyone else tried it?
where did you get the apron thanks
new one Jake and Luther have been working on, should be available for sale in a month or two.
Great informative video. Consider me a subscriber. 2 THUMBS UP
👍👍😎
Tricky!
nice. throw away that adjustable wrench is garbage. woohoo. great vid.
Just how o.O’
I just threw away two old bandsaw blades
Anybody want to offer on a couple of hacksaws I will no longer need?
wondering why sawblades even have teeth now...
just to look sharp!!! LOL
What a joke... use a angle grinder...
