I like the longer videos, nice job Matty.
Gday, I try to keep the videos to max of 30 mins but sometimes that just doesn't happen, Thanks for watching, Cheers
When doing long format as required, viewers such as myself LOVE it when the creator watches through and writes down "Time Stamps" that can be offered *At the time the video goes up* so (just makimg up a randon example):
00:00:00 - 00:04:16 Project intro
00:04:17 - 00:07:48 Made a poor choice (lol)
00:07:49 - 00:11:32 Sorted how to pull the fat out of the fire
00:11:33 - 21:18:18 Source more materials from "Empire of dirt" and maybe have to buy 6 Torx Style cap-head screws - and wait 2 weeks to get them.
etc.
This is because, many of your viewers (such as myself) fimd your content very relatable - but can't always watch a longer video in less than 3-5 sittings.
Having that index, my friend, will really DRIVE UP the number of FULL VIEWS" you get - and what with the time it takes to do all the filming - I honestly believe taking the time to watch through, and set a list of very accurate "time stamp indexes" - one time - will really make your content SHINE - because it's so easy for your viewers to find where they left off, and continue watching.
@MattysWorkshop - Give it a try. If it doesn't work to your favor, (or favour as the case may be), I'll refund you every penny you've paid me so far! 🤣
I never miss you or Kurt @CEE. I enjoy watching machine shop work and the problem solving.

Gday Loran, Great to hear you enjoy the videos mate, Cheers
No apology necessary for the longer video. Enjoyed every minute of it. :)

Thanks mate, Cheers
If a greese piston can tighten the tracks on a big excavater which is basically the same as what you have created you should have no problem pushing out a pin. The only thing that could give is the piston seal not having a backup ring but if it does its an easy fix. Soft rubber seals are the best for sealing pistons but being soft they can blowout, by putting a especial hard plastic backup ring to give support blowout is virtually eliminated.
Don't worry about lengthy videos, I love them, it means I can sit down and have a good cup of tea while watching without having to select another video still having half a cup of tea left. You create some amazing stuff in your videos, thanks for spending the time to share.
Gday Derek, the ram has been and done the job with no worries at all, I am looking at doing a small modification at sometime and may add an extra seal, Really appreciate you watching and commenting, Cheers
Great build!
Perfect length on the episode! Don't apologize for a longer video!
Thanks for sharing 🇨🇦
Gday Paul, I try to keep the videos to 30mins max but sometimes that doesn’t happen, thanks for watching, cheers
Nice build Matty. Good to see the boring bar did what was needed. You will have to let us know if it does the job for your mate. Thanks for sharing
Gday Ken, The boring bar worked better then I expected and the ram did the job, he said it made getting the pin out a simple job, Cheers
What an incredible build and the performance of the end result was top notch. I’ve never seen a jack built like that using grease so its good to learn something new. Keep these great builds coming.
Thanks Steve, Appreciate you watching mate, Cheers
Track adjusters on a lot of heavy equipment use grease rams. You pump grease into the adjuster to tighten the tracks.
I’ve used brake wheel cylinder with its cup seals and plugs to push a broken rivet out of a shift fork down in a transmission. Used a bucket model high pressure grease gun that had a long hose so a helper could pump it for me. Worked one time and saved disassembling the machine, didn’t work the second time and I had to split that one and put shift fork in a press to get the rivets out. Cylinders were about 1” diameter x 2-1/2” long so pretty compact.
Gday Jim, thats a brilliant idea, I would have never thought of using a wheel cylinder, I must remember that mate, thanks for watching, cheers
Nicely done mate.
Re the orings, they're easy enough to spec. For a dynamic seal like that, around 10-15% compression and 70-80% fill gets you the right seal.
Then it's selecting a cross section, there, the bigger the better. Stops it twisting, gives more tolerance etc.
So assuming that bore was 50mm, a 3x44 oring would be a good size.
That then puts the bottom of the oring groove at 44.75mm ± 0.15mm, that gets you somewhere in the 10-15% mark.
The oring cross sectional area for 3mm diameter is 7mm, so 70-80% fill means the grove area needs to be between 8.75 and 10mm².
Assuming you hit the groove depth tolerance, that gives a width of 3.565mm ± 0.13mm
Given the interdependency of the tolerances and that you cut the bottom and sides pretty much at the same time, it's better to aim for the groove depth to be on the shallower end, cause that gives you a bit more room for the width to go over. If you end up with a 44.9mm diameter groove the width can go out to 3.92mm and still have everything in spec.
Gday Daniel, Thanks for the great information, much appreciated, Cheers
Top job mate. Another new toy for the shop. Thanks for your time and the videos mate. Have a good one 👍🇦🇺
Cheers Mark, appreciate you watching mate...
Well done Matty. I can’t believe how well that worked unbelievable power.
Thanks mate, Its got the push thats for sure, Thanks for watching, Cheers
Proper sorry to hear about this setback, the missus had the same thing, only on her tonsil, about 15 years ago. She kicked it's arse, didn't even shut her up!!! Stick in there Matty, you'll soon be back on top.
Superb vid Matty. Always enjoy watching your projects taking shape.
Thanks Doug, appreciate you watching mate, Cheers
Actually, between the boring bar AND your new grease ram, you made yourself TWO really nice bits o' kit there, Matty! We should be able to give "10 likes out of 10!"
Thanks mate, appreciate you watching, cheers
Great video, Matty! That cylinder will come in handy! Big power in a small package! Thanks for your time and sharing! 👍😎✌️
Thanks James, appreciate you watching mate, Cheers
I see Matty's hydraulic workshop coming soon, nice job for a first time.
Gday, Not sure if that'll happen mate, Thats a bit above my skill set, Thanks for watching mate, Cheers
Excellent, was happy with the longer video. Great result.
Gday, glad you enjoyed mate, thanks for watching, cheers
Brilliant, designed off of the back of an idea, top quality, so how long before Curtis has you building and repairing Hydraulic cylinders for him😄. The video was not to long, great work.👍
Gday Don, don't think i'll be repairing cylinders any time soon, Thats a bit above my skill set mate, I try to keep the videos around 30 mins long but sometimes that dosen't work, Thanks for watching and commenting, Cheers
So cool of you to show the chamfering hand movements!
Glad you like that mate, Cheers
Thanks again for another fun, educational and interesting video.
See you again soon.
Thanks Darren, Glad you enjoyed mate, Cheers
This was awesome Matty. I Smiled big when it worked.
Thanks Lisa, I smiled big time to mate, Cheers
Create video Maddie I wouldn't worry about how long it is your content will support much longer videos thank you for sharing
Thanks mate, appreciate you watching as always, Cheers
i watch these when i am kicking back. so longer means more kick back time.. i am okay with that.... i am also retired and look forward to my kick back time, watching longer videos
Gday Paul, I try to keep the videos to the 30min maximum but sometimes that doesn’t work, glad you enjoyed mate, cheers
nice work young sir.
l always enjoy your video's, don't apologize for longer ones, keep up the good work.
Thanks mate, appreciate you watching and commenting, Cheers
Hi Matty, be careful of the grease nipple check ball, you may get a situation when the cylinder is under pressure with no grease gun attached, I have seen the check ball shoot out like a bullet. As mentioned in previous comments, earthmoving equipment have a similar setup to apply tension to crawler tracks, I have a spare check valve if it is any use to you, it basically is an oversized grease nipple with a heavy duty check valve inside, a tapered end and a groove cut in the mounting thread allows relief of the grease when required by loosening.
Gday, Ill keep that in mind about the grease nipples, Cheers
A really handy hydraulic ram, designed as you went along and looks great.
Thanks mate, Appreciate you watching and commenting, Cheers
Awesome job Matty. No leaks to say you winged the O rings. That's my way of working, lol. Great finish off your lathe. Tony
Gday Tony, I was surprised there was no leaks especially around the weld, thanks for watching, cheers
I've recently started using coolant when parting of on my Myford ML7 and it has made a hell of a difference compared to cutting oil, nothing fancy just stuff in a spray bottle.
Nice job mate.
Gday Sid, Coolant is the only way to go I think mate, Thanks for watching, Cheers
Very interesting video Matty. I think for high pressures you need seals with backup. I am not sure o-rings will work, especially for 10000PSI.
Gday Robert, the ram has been used to do the job it was made for and it worked with no problem, if anything I could put a second o-ring in the piston, Thanks for watching, Cheers
Back in the day..... I removed locating pins in blind holes: drill, thread, install grease flitting in the pin, and jack the pin out with a grease gun.
Gday Don, ive heard of this being done before, works very well, Thanks for watching, Cheers
If you had been born during the Eqyptian"s era, I am betting they would have made you Pharaoh by moving massive weights with a simple looking tool (@@)! Matty, this concept totally floors this ole fart! Thx and hats off to you mate :-) Oh, the machining was awesome, and well filmed 👍👍
Gday Bear, thanks for the kind words mate and appreciate you you watching as always, cheers
Great video and great job!! I actually enjoy the longer videos so no worries, the ram came out beautifully mate! Keep em coming!
Gday, Im glad you enjoyed the longer video and appreciated you watching and commenting, Cheers
@@MattysWorkshop I really did! Thank you for all the work you put into making them, I know I really appreciate it, cheers my friend!
Lovely job Matty 👍👍👍 Never would have thought to use grease, brilliant idea. Cheers, Alan.
Gday Alan, it worked better than I expected mate, appreciate you watching, cheers
Matty- your wing it videos are great! Sometimes just starting is the hardest part. Next to cleaning up the shop afterwards! 😮😅😂😊
Gday, I’m not that good at planning out a job and most of what I do is under the “wing’it” theme, thanks for watching mate, cheers
Nice tool Matty, I like it.
As a Dutchy living in the Netherlands I have sometimes troubles understanding your language, but the pictures tells everything..
Your electric woman (Madame Électricienne) from the other end of the world...
Gday Jinny, Glad you like it mate and really appreciate you watching and commenting, Cheers
That is beautiful.
It constantly amazes me how easy you make it look to get poofteenth perfect measurements and fit.
If I can do it mate you can to, thanks for watching, cheers
Hi Matty. After seeing your custom boring bar working well, despite all that overhang, I'm making one too. Awesome video!
Gday Ricki, The boring bar worked brilliantly even with maximum stick out, definitely make yourself one mate, Thanks for watching, Cheers
We can see tremendous force on tracked skid steers etc where they use grease rams to tension the tracks. Hope you can provide some future feedback if your pal was successful at pushing the pin out in the restrictive space
Gday Paul, he has done the job and said it worked great, it made getting the pin out easy, Thanks for watching, Cheers
@@MattysWorkshop Good to hear it got the job done :)
Another fantastic result as per usual 👍
Thanks for watching mate, Cheers
Nice build. If you know the PSI, you can calculate the force. Basically it is your input psi times the area of your piston. The force on the O ring is probably very small especially if you have a tight tolerance between your piston and cylinder. You should be able to apply some pretty massive forces with this setup. It is probably more than your hydraulic press could handle.
Gday Doug, im going to send the specs of theist a mate and hopefully I can get a rough figure of what it'll push, Thanks for watching, Cheers
The latest cordless grease guns from Milwaukee and dewalt can go up to 10,000 psi. I imagine that’d give you more then enough oomph in that little ram :)
Nice job! You winging it turned out great!
I wing most of my builds here and most of them work which is a bonus, Thanks for watching, Cheers
G'day,
A awesome build. And i enjoyed the longer video.
✌️Peace
Gday Kevin, glad you enjoyed the longer video mate, Cheers
Very nice Build Matty
Thanks for the video
Thanks Frank, appreciate you watching and commenting, Cheers
Excellent build and video! I have a Cat 225 excavator that uses a grease cylinder to tension the tracks; & have always been impressed with the power of grease.
Knowing just how much force you could exert using a grease gun would be very interesting.
Thanks!
Gday, it amazing how much power can be generated through a simple device mate, thanks for watching, cheers
Another awesome job Matty
Thanks very much Mark, Cheers
Great build Matty! Top job mate. Cheers from the UK Sam
Thanks Sam, appreciate you watching and commenting mate, cheers
Excellent build Matty, I do alot of hydraulic Jack's, great video, keep'um coming.
Thanks mate, appreciate you watching, cheers
Thanks great build, fun to watch.
Thanks David, appreciate you watching mate, cheers
Really interesting project Matty and well done! Really like the fact that you went from concept all the way to test run at the end. Well done.
Gday Marshall, The idea worked ands better then I expected, Thanks for watching, Cheers
Impressive results. I wonder if the o-rings held because grease is so viscous. Love the finish you were getting. Cheers.
its holding quite well mate, Thanks for watching, Cheers
Brilliant idea
Thanks very much, cheers
Very nice. I agree - your friend can borrow it for a while. Hope it comes back with no dings in it.
Gday, I have it back and it done the job it was made for, think it’ll come in handy one day, thanks for watching, cheers
Well done Matty!👍
Thanks mate, Appreciate you watching, Cheers
G'day wicked build Matty
Thanks mate, cheers
Good one matty awesome build
Gday Brad, hope your going alright mate, cheers
Really incredible finishes you produce with that lathe! That grease ram is a smart idea! I'll bet you could build and sell those. I have seen a lot of YT mechanics struggling with stuck pins. I would like to hear a follow-up from your customer on how great it worked.
Gday, Its been and done the job and worked great, it pushed the pin out, not sure if id like to make and sell these, I like one offs, Thanks for watching, Cheers
@@MattysWorkshop I know what you mean. I'm the same. Meet the challenge, create the solution, sit back, relax and smile.
Ripper effort Matty, and super enjoyable watch - cheers!
Thanks mate, Cheers
Nice job Matty. Yeah, I'd get it back too, and I'd probably charge a rental fee as well.
Gday Preso, it’s done the job and I’ve got it back, not something I’ll use every day but it’s always there, thanks for watching mate, cheers
Lovely little project Matty, to get a nice finish on the welded bit you could look into a circular insert would gove a nice radius cirner
Gday, I do have button insert but I have never had any luck using them, there are very cheap eBay specials, thanks for watching, cheers
G'day mate!!! You done good again. You have a good head on your shoulders mate. Learning a lot from you as well. Cheers
Gday, just have to think outside the box mate, thanks for watching, cheers
I Enjoyed watcing your Video Matty. Thanks.
Thanks mate, appreciate you watching and commenting, Cheers
brilliant idea Matty,
ive not seen one of these before, works great, and you said have i any spare "grey Cells"😉😉👍👍👍👍👍👍

Gday Kev, minimal brain cells required on this one mate😉 Thanks for watching, Cheers
@@MattysWorkshopdon't sell yourself short, your very inventive😉😉👍👍
take care
Kev
Matty,
That is a ‘champion build’ mate 👏👏👏
Your mate is lucky to have someone like you who can ‘scratch’ build tools like that.
Hope it works on his pin pressing job eh?
And yeah…. I think ‘lending’ it to him is a great idea 😎
😂😂
Robert
Gday Robert, its been and done the job and worked well, its definitely a keeper, thanks for watching, Cheers
Good build Matty . Similar to a track adjuster . 👍
Thanks Max, old system that just works, thanks for watching, cheers
Hi Matty, I have a number of charts for O ring grooves both for metric and imperial O rings I could send you both for hydraulics and vacuum. Just remember O rings only displace they are not compressible.
Gday Barry, sounds interesting mate, Cheers
@@MattysWorkshop I can email them to you, just need to know where.
@@barrycaudle9926 My email is ttmrj@telstra.com Cheers
it turned out good.
Thanks Dale, appreciate you watching mate, Cheers
Nice job. Looks like a winner to me too.
Thanks Tom, appreciate you watching mate, cheers
now thats a slick tool to have around. great job!
Gday, I think there will be times this will come in handy, thanks for watching, cheers
Thanks mate great episode loved it
Thanks mate, Cheers
Excelent job, it looks very nice. I'm wondering if it's feasible to build a pneumatic cylinder like this at home, for use in a hand rivnuts installation tool, but I think I'll give it a try.. 😉 If you succeeded, than I have some serious chance.. Cheers!
👍 Great build, and great vid., Thx.
Thanks mate, Cheers
That's a nice build. And it will last forever.
Thanks Rustinox, appreciate, you watching, Cheers
Good job mate !
Thanks very much mate, appreciate you watching, Cheers
You do some really nice work Matty, and you get great finishes off the lathe as well. Great to watch & hopefully learn from. 👍👍👍
Gday Ian, appreciate you kind words mate, Cheers
Bloody good job mate. Didn't know you could get 10,000 lbs out of a grease gun!
Gday, Grease guns put out a lot of pressure and more then I originally thought, Thanks for watching, Cheers
Nice turning job with excellent finishes. What tips do you use and where do you get them?
Gday Warren, the inserts I use are TNGG, I buy these from livetools.com.au/ here in Australia, thanks for watching, cheers
a good build,i woud most likely have done 2 or even 3 grooves for o-rings on that piston to stabilize it under pressure
Gday, So far the single o-ring has done the job but if it ever gives trouble its not hard to make a new piston with more grooves, Cheers
I have done hydraulics for many years. the support must be at the top, the tolerance between the piston and the cylinder must not be too large .. normally there is a guide band on the piston
good video matty
Thanks mate, Cheers
Great little project.
Gday Bill, thanks for watching mate, cheers
you could actually add a pipe to it that went from the valve to the top above the piston so when you reased the valve the grease would go into the top half and push the piston down.
good little jack, might make one myself for fun.
Thanks for watching and commenting, cheers
Very nice job. Really.
Thanks mate, Cheers
Great job
Thanks mate, cheers
Nice job 👍👍👍
Thanks mate, appreciate you watching, cheers
Hi Matty, worried you would blow out th O ring without a backup ring but the proof is in the pudding, nice job.
So far its held up alright, Thanks for watching mate, Cheers
probably worth putting spring to return the grease on the top side
Thank you!
Thanks for watching, cheers
Just 2 spanner wrench holes for the nut. I wish your mate would video the pin extraction.
Thanks for sharing 👍
Thanks mate, Cheers
Nice one !!
Thanks mate
Hey Matty if you ever machine something undersized just run the knurling tool over the offending area and it will raise the dia. A few thou. Usually gets you out of trouble
Gday, I did look at this off camera, I have a scissor type knurling tool and it wouldn't open up big enough, Thanks for watching mate, Cheers
Metric is used more throughout the world I believe Matty, so no harm doing metric 🙂
Gday Robert, I use both which is probably a bad habit, Thanks for watching mate, Cheers
Well Matty your some guy, great job pal 🤗👴🏻👍
Thanks Terry, appreciate you watching mate, Cheers
Very tidy mate nice job
Thanks Danny, appreciate you watching mate, cheers
@Matty’s Workshop I have the same lathe as you have 960. I have put a 3 phase motor on it and have varying speed control, bloody great... Really enjoy your work it has given me a heap of ideas.. Keep up the good work, and I hope to catch up with you one day
@@dannygreene4594 there a bloody good lathe and I really can’t fault mine, I did wish it had a foot brake for certain jobs, where abouts are you mate
@Matty’s Workshop I'm in Gisborne NZ, retired Train driver and you?
@@dannygreene4594 I’m in Eden on the far south coast of NSW, retired truck driver
yes enjoyed it !! i have never seen or heard of one of those,, where did you get the idea??👍👍
Gday, the idea came from thinking outside the box mate, thanks for watching, cheers
You showed me what I’de been doing wrong, course I’m pretty much self taught.
I’m only self taught to Ron, thanks for watching mate, cheers
Matty - Let me tell you something that you already know. Bulldozers and other Track Machines - tighten the tracks
using a greese gun. Now I feel better. -- Jim
Spot on Jim and i've had to pump plenty of them up over the years to, Thanks for watching mate, Cheers
Very impressive my friend and dam how do you get the finishes on steel like that I really enjoyed the video
Gday Ralph, I use TNGG inserts and knowing the speeds and feeds, you can get the same mate, Cheers
Incredible work Matty, I was wondering, would using engine oil work?
Gday, I’m thinking with oil it may need a lip seal on the piston I say, thanks for watching mate, cheers
I think you may need an air bleed hole. Nice long video.. Than Matty
Since there is no O-ring around the shaft at the top or one on the cap to barrel surface should bleed the air okay.
Gday, Theres no seal in the top screw on cap, air can bleed out there and theres very minimal in the piston side to be of much concern I believe, Thanks for watching, Cheers
A suggestion, get rid of the zerk and screw the hose straight onto the ram.
Gday, not sure if that’s a good thing, a least with the zerk fitting you can take the grease gun away if your in a tight spot and be able to put the grease back in the cartridge like I showed, thanks for watching, cheers
