Brobo Leadscrew 

Greetings and welcome back. It's a new year so let's do the checklist: 1. Health update - sounded boring which is good in medical matters (hope it stays that way) 2. Commissioned job - worked to get a mate out of trouble, excellent 3. Chips - suitable amount of metal sacrificed while extracting those part from stock, nice threads 4. Coolant - present and flowing well 5. Mistakes/complications - just enough for keeping the narrative interesting All up - well done, and carry on. Thanks 😉

Sometimes Matty it's just easier to make the whole thing 🙂 Nice job as always 👍👍 Cheers, Alan.

Always a good day when you put up a new video Matty. If internal trapazoidal threads were easy to male we'd surely see them in more places. You got the customer working again which is the important thing.

It's good to see you can find the energy to do things. I know it's the hardest part. As for grinding a cuttung tool, the next one will be spot on. I'm sure you will figure it out.

Would say fellow is happy, no matter what thread as long as it works 👍 great job, good to see ya back!!!

Good to have you back Matty. Hope the scans reveal some good news for you. The job came out real good in the end. Yeah, sometimes things don't go as planned, so Plan B has to be put into effect. Keep the videos coming mate. Cheers.

Nice work my friend you must be feeling better. You look 100% better. Carry-on.

Thanks for sharing, Happy New Year

One thing Matty is great at besides machining, is going out side the box to make a project work even if it takes another way to approach it! Great first video for 2024, and your looking top notch mate. Keep on Keeping on, and old Bear knows your scans will be positive as mine were. Best to the Misses, Bear.

hi Matty Turned out to be a bigger job than you thought, were there's a will there's always a way great 1st video of 2024 see you next time best wishes Kev (uk)

Good to see you back in the new year Matty. You did well to get the job done with the materials you have on hand. I hope you have good news from your results.

Nice work regardless. Onya Matty.

good to see you at work in the shop. nice little project to begin the year with.

Looks good from where I'm sitting. Thanks for your time.

Hhey there. Matty, good morning to see ya! The ability to complete the task,in a different but acceptable fashion is a win no matter what transpires. Well do ne. Matty 👍🏁🏁🙏

Great first video of 2024 Matty! Man, I gotta say... you are looking a lot better than you did in your last video. You color seems better and you are right orney again!!! That's our Matty... fight a Brown Snake before breakfast, and a Great White after lunch and still be man enough to take all the women home at last bell. Hope your health continues to improve and I hope the rest of your 2024 is awesome.

Always a pleasure to watch Matty. That'll last 50 + years. Why make more work? It's going to do the job just as well. ATB Tony

I'm glad to see you back. Keeping you in my prayers that you beat your medical condition. Keep up the awesome work and videos.

Plan B worked fantastic, nice work!

Glad to see you well enough to go in the shop.

Welcome back Matty, Happy New Year to you, glad to hear you are feeling rested and hopefully the scan comes back with good news, those parts came out nicely even though you couldn't cut the thread you wanted. 👍

Happy New Year! I'm not upset that you couldn't make the tool you wanted ... it gave us a longer video!!! Thanks for sharing 🇨🇦

Hey Matty, thanks for bringing us along with this one. Cheers 👍💪✌

Great to see you back online hopefully your scans come back all clear and the rust is all gone

You're looking great Matty. Keep hanging on to those mill and lathe handles. There is no better therapy brother.

Happy New Year Matty! The editing and all was just fine, another good one and good job improvising a quick fix to get your mate back up and running. I do have to say you look physically healthier than you did last time. Hope that's a good sign.

G'day Matty, and Happy New Year to you and Becs. There's nothing wrong with the video! Plan B worked out ok mate, and it should do the job as you say for a good while. With that trouble with the trapezoidal thread, I would try a trick that I've done before is to grind up a parallel or just slightly tapered at no more than 20 degrees included, (and having a back rake on it so it will cut well) tool just under the tip width of the trapezoidal one and try running that through the bronze to just under full depth, then centre the trapezoidal tool in the groove and then try running it through to full depth. That gives it a lot better chance not to deflect so much as there's a lot less material to try to remove. I sincerely hope you get good news from your recent PET scan in the next few weeks mate. Cheers from England, Sam

Nice work around, to get something happening.

Happy new Year,Matty. Some of those hard bronzes like admiralty bronze and aluminium bronze can be very difficult to single point a thread in/onto. I think carbide insert would be your best bet with that task.

Some times, you just have to roll with what you've got. Good plan B Matty! Bet that V-thread lead screw and nut will work great and last a long time.

Best wishes for clear scans and smoother sailing in 2024. Always enjoy your videos and your can do/will do approach. From a long (long, long) ago third shift turret lathe operator at Standard Pressed Steel (Unbrako!) in Jenkintown, PA, USA. As youse guys say, "Cheers, mate!".

Happy New Year to you and yours Matty, lets hope it's a good one. Nice little job to start the year off with and a good recovery. It's about -5C here at the moment, I think I'd rather have your weather "problems."

I believe I have stood on that spot at Twofold....been a while since I was down your way, so I think it's time I get my behind away from work and the van out the backyard 😊

Another job in the books. 👍 We have about 6" of snow right now. I can send you some so you can cool off. 😀

Greetings to you and your family. Good to see plan B worked out well.

Thanks for coming back for us!

Good job you have to do what you need to get it working, stay safe takecare and good luck with the test's ok

Nice to see you're back! Plan A is always to have a Plan B!

Great to see you making precision swarf again Matty 👏, lucky you had some suitable bronze, not a good start when free issue isn't any good. Top notch on trapezoidal screw cutting. Great channel donation, ref Dychem. Hope medical results are positive 🙏.

Happy new year Matty, If you have difficulty grinding a trapezoidal threading tool, have a look at the dead simple jig I made for that purpose. Originally designed to be used on a surface grinder but works equally well in a mill using a cup wheel.

Welcome back Matty hope you had a good brake over Christmas with your family so good to see you back in the shop that layout fluid you can get in Australia looking forward to see more chips made in your shop all the best from my family to yours

Enjoyed the video Matty - another good result. An alternative that might have worked for the lead screw is a square thread. It is stronger and more wear resistant than a 60 degree thread form and the cutting tool is easier to grind than for an Acme thread. I had to make one when restoring my T&C grinder and it worked out ok - after I realised that the required thread pitch was 10TPI and not 2.5mm (they are very close)... Cheers.

Keep on keeping on! It WORKS!

I was happy to see you posted this morning 👍 nice job as always.

Nice job Matty. I'm happy to see another video from you. I hope you are doing well.

I am pleased to hear that you and your family had a nice Christmas. We are praying for favorable results from the scans. I was relieved to see that you were able to salvage that nice chunk of bronze. Please remember that there is a huge crowd cheering you on from this side of your camera.

Welcome back Matt. Nice save on the nut and shaft. Lets hope it's a great 2024 year

All the best for 2024 Matty.

Good luck on the scan, be going for another in a few months. Part looks great, yeah, should be good enough FOR THE NEXT 25 YEARS 😉

looks good to me!!!

Nice to see you back Matty. All the best for you and family in this year to come

Good to see you Matty, Ordinary is great.

Welcome back Matty! I hope you are well rested and healthy.

So good to see you back. Praying your report from the Scans is all positive. .

Grate to see you again, my friend . A day in the shop is a good day. Not having all the right tools to do what you have in your mind. Right on track. One more day with friends and family. A gift from God. Pray you have many more

Hi Matty Good to have you back. Great video as usual, I spent ages trying to find a 16 x 1.5 trapezoidal nut for a lead screw, got it eventually, never thought to change the lead screw. Good luck for the future.

G'day Matty great video mate

I sure did enjoy Matty ! I know what cancer is like I am a CT Scan veteran , God Bless .. You did a great job on the project ! 👍👍

Good to see you back at it Matty even if a bit rusty. Hope the scans prove to be all clear. See you soon from Canada's banana belt. 🤞🇨🇦🍌🥋🇺🇦🕊️🇦🇺🐨👍

Good to see you in action, take care

Good show Matty!

Good video, glad you're still up to making videos

G'day Matty. Excellent video, Lead screw etc worked out well with a good fit.

G'day Matty, It's good to see you back. Plan "B" got the job done.. Should work just fine. Sending good vibes and wishing the best for your health update... Cheers.....ATB...

very good job matty

Camera work looked fine! Good to see that you're up and about. I've had a couple of relation go through this and they got the piss knocked out of them. Hoping you hear good news.

It can help to pre-cut a normal V thread then use the acme/trapezoidal cutter as a form tool to shape the flanks

Thanks for sharing this project with us! As usual for you, the result is outstanding, even with the material limitations and the threading setback. I don't know about everyone else, but I am always amazed at the finishes you achieve on your work. I must be some kind of idiot. Try as I might, I don't seem to be able to make anything that looks nearly as nice as your work. Would you consider making a video sharing what you do (and don't do) to turn out these first-class finishes? Materials, tool choices, feeds, speeds - Can you tell us about the magic you use?

Good video, enjoyed watching your professional work once more. Merry Christmas and a Happy New Year to you and yours as well.

Absolutely far out Matty, g'day mate Noice to see you back and in good health 🎉 and making a cracking video after a holiday

Good to see you back will chat soon. That was a nice looking long screw 😂

Another awesome video young matty, From kiwi land.

Hi Matty, had to make a new nut for my cross slide, 14mm x 4mm trapezoidal thread, did it the easy way with a tap which I bought online. Take care.
