- Looking for the best way to sharpen your brazed carbide tool bits and save some grinder space. Here is a set of spacers to mount two wheels on one end of your grinder. Built on a Precision Matthews 1440TL lathe and Jet JMD-18 Mill Drill.
Combination silicon carbide and diamond cup wheel mounting spacers.
Thanks for watching! - แนวปฏิบัติและการใช้ชีวิต

It never occurred to me to put two wheels on one arbour.. thanks for that. A great idea.
I also love the way that you show your mistakes. I make mistakes more often than I get it right the first time. You give me hope!

@nicholashacking381 - Thanks for the comment and the sub. Yes, I think we all make plenty of mistakes, happy to share mine and try to prevent some for others. This set up works great, hope it works well for you also. All the best.
Great video found it very informative thank you for good work
Metal Shop with Troy - Appreciate the comment. Glad it was helpful.
Super underrated channel.
R R Precision Welding Group - Thanks for that comment. Growing slow and steady! 😁
Never seen two wheels back to back like that.
I have the wheels and a vintage belt driven bench grinder. Going to have to make some spacers I see.
Subbed.
Bustednuckles - Thanks for the sub and the comment. They work great together. Your vintage grinder sounds great, keep it running.
Thank you so much. All my questions were answered in the video. I did subscribe.
bernard mauge - Awesome glad it was helpful and thanks for the sub!
Also another comment: You can broach keyways on your lathe by using a piece of HSS tool bit blank the width of your keyway, and you can simply push it in with your handwheel, taking care to advance only a few thou at a time.
Tyler Fu - Yes, that is a method I have seen used before. If I needed this to be a flat bottom keyway, I would have had to do that. Since the rounded bottom would work for this application I went the quick and easy route. Thanks for the tip!
Found your site while looking for reviews on the SunMaster Lathes. I ordered the TC-1640V variable speed which won't arrive for a couple of months yet
Hope you enjoy the videos while you are waiting. What kind of machining and projects do you have planned for your new lathe?
@@BladesIIB general purpose home machine. Make all sorts of things for friends and self. Am making some tools for clock making which will be one of the things i want to try, Maybe a steam engine as well at some stage
@@mikegregory460 Awesome. Sounds like you have some great plans. Have thought about making a steam engine myself. All the best!
You can offset that washer in a 4 jaw chuck and use it to balance. Subbed
Good tip, thanks.
great video. Thank you for sharing the idea of two wheel combo. Please let me know where I can find the 5" Diamond Cup wheel. Thanks
Tinh Nguyen - Glad it was helpful. I bought both wheels on Amazon. Check out the video at 1:42 and you will see the part number and details for both wheels. Let me know if you need more info. Thanks for the question.
I used the part numbers and searched for them in Amazon website but, couldn’t find them. I’m going to try it again. Thank you Sir
@@TinhNguyen-mb7gx Try just searching 80 grit silicon carbide wheel 6” and search Poltava Diamond Tools Cup Tool Diamond. You may just have to read through the description to ensure you get the size and grit you want. Sorry the part numbers changed. I did just pull up some options in Amazon now with those search entries.
Do'in it. Dave from "Aus" Thank you........
David - glad you are finding some value in these projects. Thanks. 😁
Great video. Why not use the diamond wheel alone for sharpening carbide? I stopped using green wheels years ago. New equipment is great. European or American lathes, mills are the best.
Paul - Great question. Partly just habit and what I am used to. The green seems to remove material faster when I am shaping a new bit, but could just be in my head.
I first saw how you stacked the wheels and I tried to do it, but regrettably my grinder's shank is far too short, it has no room for more than one wheels. Not sure what I can do. I ended up mounting a diamond cup wheel on it... did not use a spacer, just installed it, then used a dial indicator to indicate it in before tightening the nut. Not sure how long it will last, but will get around to making a spacer for it.
Tyler Fu - I would definitely recommend making a spacer for that wheel sooner than later. Having that get loose and start rotating well out of round and off balance could be dangerous in a hurry.
@@BladesIIB I tried to make a spacer, but I was running into difficulties. For one thing, I don't have a small enough boring bar to accurately make a hole exactly 1/2" in diameter, and so I ended up using a 13mm drill bit that is too loose. I had to wrap tape around the spindle to get the cup wheel installed without a problem. By turning the washer around I was able to fit both the grinding wheel and the cup wheel onto the bench grinder, but I don't know how well it will hold or if the wheel will explode. I'm ordering some smaller boring bars, and proper holders for small boring bars (basically those split piece of steel with a round hole in it). I don't have a quick change tool post, so I'm stuck with using a 4 way toolpost. I tried using an end mill to use as a boring bar but it just isn't working.
I'm going to work on making a nut/cup wheel mount that will comfortably secure a grinding wheel and allow me to use the diamond cup wheel. Also ordered some green wheels for grinding carbide.
@@taiwanluthiers That sounds great. Should keep you busy for a while. With the 4 way tool post. Many boring bars have a flat and you can clamp them similar to a square tool. I hold a couple of my boring bars that way in my quick change holders.
What is the brand and model of the mill?
bernard mauge - Thanks for the question. The Mill Drill is a Jet JMD18 with power down feed. I have a full video on that on my channel as well. Will drop the link here in a minute. th-cam.com/video/UFK_klN2YTE/w-d-xo.html
I love how you fool us with the green screen behind you. It makes it look like your shop is super clean and super shiny. Not like what the rest of us have.
@robertcornelius - Ha, no green screen I assure you. Check out a few other videos. The shop gets plenty full of chips. It is just small so I do try to keep it cleaned up. Check out my shop tour video. You will see the open space to clean is minimal. 😁
Why Jet mill/drill, not Precision Mathew's?
tallyman15 - Great question. If I had it to do over again I would definitely get a PM. I had not discovered them when shopping for my mill. Almost bought a Jet lathe as well. Had it ordered when a friend directed me to PM and I changed last minute. Thankful I did. I will likely upgrade my mill at some point, the round column can be a problem sometimes.
@@BladesIIB what PM model would be similar to your Jet?
@@tallyman15 the PM 833TV looks closest to my Jet. I would likely do the knee mill when I upgrade. Similar footprint and I think a better unit for me. So would probably get the PM 935TV.
