I’ve been around cutters since 1980. Cutter blades still give me the willies!

I sharpened many of these blades as a tool and cutter grinder. They were simple compared to most work I did

@Just A Printer, yup, that first cut with a fresh blade always nice. 1 thing I did before inserting a fresh blade- I waxed both sides (with a car wax) to remove any residue from the sharpening process so it didn't drag through what ever I was cutting. Also used #20 strips of scrap for the adjustment, put 1 dead center in case of a warped stick. Man, I sure miss the trade. Kudos to you running your shop alone, neat, efficient and well laid out. Looks like you've got a great customer base !!!

Good job. I have changed over 5000 blades in my life time. Bindery Doctor

I guess I've done that 100 times on the same cutter. IN the beginning, back in 1985 when this cutter became available, the steel blade was not durable and needed sharpening at least 1x a month. Then it gradually changed to 1x a year, and only because we were speechless and felt it should be changed!!. They called this blade high-speed steel. Our cutter came with 3 blades, and the 2nd one also. We never interchanged blades... and we used both about 6 hours a day. All fully loaded and possibly the best bindery equipment purchases we ever made. Good teaching video Dan.

Bless you! I have been struggling trying to figure out how to get the blade back in to a Multi 2020. This was close enough to get me there and get it done!!!

This is great. I just acquired a 1995 Challenge 305 MC with Microcut Jr... a huge upgrade from my old Challenge 305 with a hydraulic retrofit and a screw clamp. Instructions will help me get this perfect the moment we get it wired up.

Great video, thank you! The sweet sound of a sharp blade 🙌🏼😁🙌🏼

OMG! I'm addicted to your channel. I'm a 30 year ex printer (well, once a printer always a printer) of offset and digital. Changing a cutter blade was my favorite thing to do. You are spot on with the safety aspect of the change. The bare edge shouldn't see more than 2 seconds of free air as it goes into the cradle. It looks like you used cover stock to set the blade. I always used 80# gloss text. Don't know if it makes a difference, but I do like hearing the snap. Thanks for you channel and keep it going.

Your video has been very helpful. I work in a printing shop and we have a model just like this. It’s good to see the steps on how it’s properly done.

For moments like 10:34 i really love your work. Thanks for sharing it, Dan!

Hello I like what you are doing same as here. Thanks for sharing information.

Hi Dan, I came accross your videos by accident, looking for information on my next digital press purchase. Must say I am hooked! I too am a single person operation over here in Australia and like you am still excited about print. I am 46 years old and started my offset printing apprenticeship when I was 17 (how the industry has changed since then). Keep up the videos, you will find a growing audience due to your easy style of presentation. I might get the camera out and do a quick print shop tour myself one of these days. I am currently looking at the KM C3070 and the Ricoh C7200, I currently own a KM C1060 so the Konica would be the obvious choice but need to make sure I look at all options. Keep the videos coming, I will spread the word in Oz! Regards, Robert.

Love that sound. She is running great.

Can’t tell you how many times I’ve had to train people on this. Next time I’ll just forward this link!

Very cool channel. Nice to see someone doing this.

A high volume shop might need a fresh knife every week or two. More swaps = more opportunities for mistakes. So, one minor change in procedure is worth considering -- after the knife is lowered into the stick and the pump is off, before any other steps are taken to remove the dull knife, the depth-of-cut screws should be backed off the appropriate distance. Doing this as soon as possible makes it much less likely that interruptions or any other Influence will result in the forgetting of this very important step!

Thanks for sharing your work!

Im cutting here in taiwan but i like your cutter so cute 😅

Thanks. This video helped a lot.

Hi Dan, maybe you have a hint why printed backside of paper gets a little rubbed? changed blade to even new and the cut sticker also.. you dont notice until you have cuts with gloss paper and with color bleeds..

I had a 305, makes me nervous just watching you change it. Only thing i did different was i took the bolts out and left the handles loose and then let the blade carrier hold go back up, leaving the blade behind.

We have polar straight knives. You should look at their blade changing brackets they have. Makes it easier to not nick the blade on the way out. You only have to lower the blade maybe 2” to the bracket.

thank u Sir

Suggestion. Get a 9/16 racheting wrench for doing the blade adjustment

My adjusting screw seems to be either cross threaded or fused in place. I’m afraid to wrench on it and break it. What do I do?

I have a problem with my Challenge 23" MB cutter, I ran out of hydraulic fluid and when I put more in, still not working right, slow and sluggish, I think there is air in the lines. Is there a way to bleed the air or get the fluid up to where it should be?

You just save my fingers. I was going to do it all wrong.

Have you seen the videos by the hydraulic press channel that show what happens when you "cut" a stack of paper with a "maximum dull knife" (i.e. a flat piece of metal)?

Check for edge bow and flat bow

My wife has a Sunray 433P that she uses for book binding. She recently changed the blade with reference to your video, thanks. Her problem is that she can’t reset the “warning knife change” alarm. Could you please recommend a course of action or any one who might know or be of assistance? Thanks

Hello, how are you? Please, I have a question. I have one hand. Is it possible to use it by hand?

Since how many years are you running this cutter ? If you ever come to buy a new one, which paper cutter will you go with ? For industrial use Polar Mohr's are now the best ones but there is a US paper cutters brand called Prism which are amazing too.

very cool video, big fan - does anyone have resources on where to Wax and Oil a guillotine machine? i inherited one and i want to maintain it properly

Thanks!!

I’ve never understood this machine. How do you perfectly cut all the sheets to be exactly the same size? How are Crop marks on sheets aligned how to the machine? If it’s just a visual alignment isn’t that inaccurate?

nice job you do can you tell the size of box you use for packaging Books and the business cards

Ever put a sheet of paper under the cut stick to correct low spots if you have any?

Would it not be safer to rotate the cutting stick while there is no blade installed? Seems like there's still a chance your hand could slip and end up catching the bottom of the blade when you're trying to pry the stick out.

Do you get to adjust the back fence to be parallel with the knife? How often would you say?

Had to change the blades on my cutter last week. It was a little sketch for a moment. Potentially very dangerous.

Having been here for just a few episode I have to ask - Did you start your YT channel so that you have someone to talk to? 😊

I am negotiating a click charge for digital press, at what inking rate do you recommend ?

I had a question about the challenge 305 and was wondering what you thought. I'm considering buying this same machine but I've discovered that Challenge no longer backs any of there machines with Parker valve systems. And in fact suggest they suggest that any of these older machines be scrapped. People selling these things like they are going out of style LOL. To me it all sounds bogus considering that they base it all on one incident that a cutter failed and cut off his fingers. Can you give me any advice or provide a resource that could give me an honest opinion on these machines. Also, my name is Patrick. I accidently used my wives account lol. Thanks!

how often do you change the blade pls ?

sharppen the knife at 24° angel to add more life to the knife

Your cutter is a littler easier to change. We have a Challenge 42" the blade length is 52 inches. It's heavy. Like some one else said changing the blade give me the willies. To me it's the most dangerous job in the shop.

Why dont you replace cutting stick before put the blade 😅

Knife drawn

Wear kylar gloves

Knife draw

indeed that's sweet hhhh

I sweat whenever I watch you use this machine. Yikes.
