- Topper Machine LLC gets lots of jobs, some small, some big, but we almost always get emergency rush jobs. Being able to handle these is critical to a job shops survival. Watch as we make quick work of this repair.
Follow up, the customer had it back in their saw and running the next day. They only lost a little production and saved a lot of money by having us repair it.

I purchased a coaxial indicator in the 70s it was American made and quite expensive, but paid for itself in no time!
Keep up the good work!

Josh, way to power through sir. 100+ degrees, no AC, and busting your hump for your customer so he or she is not left dead in the water with no saw which equates to no lively hood. I wish everyone had your dedication.
last week I offered you to move to Texas. No AC: Texas moved to you! :D
Have some fun on your time off.
Fans n ice water. We did it for years at Madison Machine in Adrian, Mi.
We used to call the rush, emergency jobs "hot jobs". It was an easy way to let the team know and be aware in the shop.
Is that the town dump in your intro behind you?
With the Coax, get it close then turn the machine on slow speed and move the table until the needle stops moving.
You got it done.
One happy customer ready to tell his mate the great job you did that saved his ass.
That's how a business grows.
👍 saved the day again!
Great work, done in short order.
Have a good holiday.
Thanks for sharing.
I would really like to see the saw made! My next door neighbor had a saw sharpening service and I was amazed at what he could do with a saw. Some of them were 7' in diameter and hung over the sides of his little flat bed delivery truck.
I'm more interested in the hammering of blades. I really want to learn, but there are no classes anymore.
The hold was out of roundness, wooden it have been easier to get the center by indicating on the outside of the center piece?
Maybe I’m lacking in knowledge but I would used some softer metal between my hammer and the thin thickness of that finishing to prevent damage to the edges of the bushing.
Fantastic, with your time constraints have you ever used dry ice to shrink your piece and just drop it in and let the ambient temperature swell your bushing in place ?
Yes, problem is the nearest dry ice source is an hour away. So it wasn't worth 2 additional hours to get it done.
Love watching your videos and I learn a lot, wish I had a shop to use my new knowledge in. LOL
Very nice job.👍
👍
👍👍👍👍👍
Good job.... Thanks for the video...
Would it have helped to freeze the part in freezer & then just drop it in. We have used liquid nitrogen at times as it cools quickly & the parts go together as a hand fit. Have also used a bag of ice & water to bring it down in quick fashion. I do love that boring head. If you ever get a name / number please post it so I can try to source one. Thanks for the video & enjoy the time off.
Good suggestion, and yes it would have helped. I would have chilled it,but time was critical. I usually throw the part in the freezer for an hour and good to go, or use dry ice. When I shot the last scene, the customer was pulling in the driveway. It was a true rush job. Thanks for watching.
@@TopperMachineLLC You do the best you can with what you've got in the time you have. Keep the good vids coming!
It would be very interesting to understand the principal design of this indeed nifty boring and facing head.
I use a C02 bottle with a regulator and a spary nozzle aim nozzle inside work keeps it cool and no water .
Nice job, not too many job shops left now days. In Milwaukee area their use to be hundreds of small machine shops now most all are gone. If you need one off part or a repair good luck.
I hope you have a great holiday and get to relax. This was a really interesting project, thanks for showing how you went about doing it. The coaxial centering indicator looked like a very useful tool, I will have to price one up over here. The new saw blade is a beast
If you can get one of these indicators, I would jump on it. It's super handy. The new blade is beautiful and I'm excited to run it.
@@TopperMachineLLC I have just ordered one of those indicators, by coincidence I believe it is coming from the UK company you bought your DRO from. Thanks for the recommendation
@@GardenTractorBoy was it from the Allendale Group? If so, they are great to work with. Enjoy your new indicator. It's been a great addition to my shop.
@@TopperMachineLLC Yes it was from the Allendale, we need to talk to them about DRO soon too. We are working on getting a second mill and some workshop changes so hopefully it will be a great addition. Thanks
when i bought my co-ax, there were only maybe 2 choices - mine cost $315 about 30 years ago. been retired 8 years now, yours is a great "nostalgic" channel. curious as to weather you have some of the "obscure" attachments for the mill, such as (bad phonetics here) "voll-strol"
I can't imagine using a lathe without coolant! Last time i did that was in 1964.
Bonjour je vient de tomber sur ta vidéo. Juste une remarque tu aurais du chauffe ta poulie avant de rentrer ta bague avec avec 0.1 de serrage elle serais rentrer toute seule sinon ta vidéo est super
Years ago I did a very similar job but what we didn’t know was the face we clamped down wasn’t square to the bore so when we machine it the wheel had a wobble so we clock up the outer wheel face using a rotating table and re machined what should have been a simple job turn into a very complex job suck a life for a machinist
Nice work on the wheel bushing job 👌🏽👍🏽. I wonder if you would give us a hint of what your shop rate is? I have a small home shop with a Bridgeport mill and a 13 x 40 lathe (with COOLANT ;) along with plenty of other tools and tooling. I set it up for myself but I found that a LOT of people hear that I have this stuff and want jobs done.
Any other subscribers around the country or world are more than welcome to come in on their rates too. Thanks!!
100° F => 37.7° C, 90f 32.2c
Heck of a big wheel
You could use more lighting?
Hi nice video. What is the make of that indicator. The price sounds very good.
Thx
Like the shirt. Any videos on you building the saw blade ?
Good Job Josh, Just subbed. Do you ever find on your press fit bushings that they become loose over time without using Locktite ?? It looks like most of the jobs that you take on the customer is not " easy" on their equipment.
I haven't seen an issue yet. Usually I do shrink fits, but this one was a time crunch and at the time supplies were 2 hours away, so had to make it work quickly. It is still running in 24/5 service without fail.
Great Video. Question. When you do a bushing like this where you have a small interference fit on the OD and need to hit a tight tolerance on the ID does the ID get smaller by the same amount as the interference of the OD? Is that a predictable outcome?
Good question. Short answer, yes and no. Sometimes I have to go back and bore or hone the ID. Sometimes it comes out perfect.
Don't you have a coolant pump on your lathe?
Stick the sleeve in the freezer for shrink?
Wasn't time. Customer was down and waiting for it. I had to rush this one through, but it went well
What is that green lathe?
You do dam nice work . I worked in a smaller Foundry for 19 years in Indiana and i always wanted to get into the machining part of the Castings we made but we just sold the raw castings but we did have a Bridgeport and a Lathe just like you have in the Maint. room that i had used whenever they were free on projects id bring from home ...Keep up the great work
liquid nitrogen?
Heloo one link for my a pay for borning head adaptor? Thank You.
Why don't you freeze the part and flame heat the flywheel....
If I had more time, I would have. But the customer was down and losing $$$$$/hour. Get it done fast!
Why didn't you put that bushing in the freezer for an hour or even 30 min, as it would have shrunk more than enough
Time. I was against the clock to get it out of here.
Put it in the freezer?
If there would have been time, yes. This job was against the clock, holding up a major mfg in my area.
Wow, another video that I missed. You are something else or you just do not know when to say no. Some of the things you work on are big and heavy; I sure hope that you do not hurt yourself. You willingness to do the hard jobs and even with such tight time limits is a tribute to your dedication. It is always good to see you. Thanks for the video.
Great video
Why didn't you use your big lathe?? I know, its not a gap !! I dis agree with your indication !!! What If that ID is bad !!! Shouda swept the O.D.
I must admit parts getting hot is a new thing for me, when I learnt all the cutters were HSS and we used a lot of coolant. If I ever get my hands on a lathe again this heat thing is something I am going to have to be aware of.....did you go somewhere hot?
