[@CraigsWorkshop]

How much more cross-discipline can a single project be? Turning, milling, sheetmetal, painting, electrical, heat treat, casting, etc. Also loved the discovery of hidden features, and the improvements to the chiptray, switch, etc. This saw will go on to work for another few generations, I'm sure. Great work - and nicely edited. Bravo! 👍

I’ve been a welder for almost 30 years and despite Jeremy swearing this will never be a welding channel in at least two earlier videos I’m pretty confident I saw some welding as well! Nice vid

[@rallymax2]

OK, let’s break this down. Turning, milling, brazing, re-bushing, taper pins, broaching with a shaper, welding, casting, sandblasting, painting, ratchet replacing using Joe Pi consumable jaws, hardening and tempering, electrical wiring, table fabrication, ball turner, knurling, river mystery metal and a beautiful restoration. This could have been a 10 part series but you made it a condensed joy. I know doing it and filming it took a loooooong time, so thanks so much for this video.

Dear Lord, under which rock in which river did you find the mystery metal for the Tommy bar? Looks like it was forged at the birth of the planet 😂

[@Vandal_Savage]

I thought it looked suspiciously like one of the nails Noah used to build the ark...

[@nefariousyawn]

I was thinking it was salvaged from the Titanic.

I thought he dug it out of the garden. The spade tine broke off some time in the mid 1800s, and has been in the dirt ever since.

[@JeremyMakesThings]

Ha ha. You guys must be new here, welcome to my channel. That sort of stuff is par for the course around here. What it actually is, is an axle shaft I pulled out of a river bank in a spot where there are a bunch of old auto parts dumped (old enough that I also found a Model T driveshaft there). I like old axle shafts because they’re w good steel, but not too hard to machine.

[@barthanes1]

So @throblet was right, it was the river. Thanks for clearing up the mystery.

[@JimNichols]

I am usually quite the cantankerous old mechanic guy in the comments BUT I can find no shade to throw your way. You embrace silence in your videos where silence should be and allow the sounds of the shop ambience to make the music (that you do not have to search for on the internet as non copyrighted) You have a nice grasp of repair and refurbishment and are quite a good mechanic. Bravo. Edit: You and I must be kin, all the cool toys and the ability to sand cast. Milling and making things that are "right" because you can. Again I salute your abilities. I got tired after 40 years of mechanical, electrical and machine work sold all my stuff and moved to Thailand. Truth be told I miss the ability to make or repair anything in my shop... (sad smile) lol thanks for the ride along and the nostalgic look back at my life trough your camera.

[@briancurle6223]

Not seen the collet chuck used as wrench before, gret idea, nice work

[@ronwilken5219]

I was going to comment that the hole in the body was for a shut off switch but you worked that out and installed one. But you made it actuate horizontally. I was going to comment that on my 4*6 saw the switch is inserted so it works vertically. But then I noticed that you fixed that on your own so there wasn't much else to comment on other than the piece of scrap iron for the tommy bar. But someone else beat me to it with the Noah's ark nail joke. So despite having been beaten to the comments by everyone else I'll join them in saying great and thorough job both on the saw, recycling ancient steel and aluminium pop cans and the video. Simply put. THANKS. Regards from Canada's banana belt.🤞🇨🇦🍌🥋🇺🇲🕊️🇺🇦👍

[@blahblahblahblah2933]

After making a new pulley, I was wondering how much harder it would be to remake the shaft. But I guess some problems solve themselves. Nice work! Power hacksaws are neat.

[@JeremyMakesThings]

I would have been more inclined to do it the first time I’d the gear wasn’t pinned on and if my lathe would hold a closer tolerance, but I got it done in the end.

That's a cool trick I haven't seen before. Use a collet in the tail stock to tighten something without flats on it. Nice.

[@ronwilken5219]

Ross, I have a Myford with a threaded mandrel. I made a back plate for a 5C chuck but had forgotten to drill a hole in it for a Tommy bar to help remove it. I used the lathe chuck, jaws reversed, clamped to the backplate to remove it. More than one way TSAC.

Hi Jeremy, Was this uploaded in 360P, or did you not give YT time to do its internal processing before your made it live? A half hour video needs at least 20minutes for YT to do it's AI magic on before it is available to viewers in HD.

[@bengrogan9710]

A nice working restoration Only 2 real comments - 1st: your question on what to do with the badges - My suggestion is cold blue them and and then rub the raised surfaces on some fine grade sand paper, should give some visible contrast 2nd: I'd recommend a small addition for your own sanity - Add 2 rest blocks on the new chip tray - one close and 1 at the far edge as outfeed supports, If you add a small leather strap like a watch or small belt you will mute almost all stock vibration on the front and likely stop a good amount of drop damage to the tray over time

[@dannycoots9503]

Great work

[@ronwilken5219]

Then you missed his rebuild of his Crane's hydraulic cylinders part 1. I say part 1 because they're a phuqing disaster. He's going to have to remake them almost totally.

[@aaronshapiro2542]

I love old machine badges, but you're right restoring them doesn't work. maybe hit them with a dark patina solution, then a light rub on fine sandpaper to polish the high spots.

[@ADBBuild]

My dad used to have this same model saw. His had a custom chip pan and flood coolant. He got rid of it when he got a horizontal band saw. MUCH faster, but definitely less cool.

[@Kevin-wj4ed]

Just awesome

[@mosfet500]

Thanks for the video. I restored one of these, I had the same problem with the 10 tooth blade on your saw at the beginning. These saws just don't run on anything less than 14 teeth. The other problem is the raising mechanism, I got it to work but it was never great, I'll have to come up with a better system or just let the blade rub on the return. I have a power band saw but these saws are great for carbide blades cutting through hardened steels.

[@joell439]

[@swampy1584]

[@jeffreyhallam5517]

Ah! It’s beautiful. I have long been enamored with that odd power hacksaw in the background of your videos. Until KZbin I had simply never seen one of it’s kind. …or well, any machine tools until This Old Tony. Now I have a home machine shop but I digress. It’s such a cool saw. The weird green was ugly in a fun way but I much prefer the blue. I love that you cast your own pulleys when ever the need arises. I know you just cleaned up thee stand but I have a recommendation that I bet you’d dig. I mounted a 4x6 band saw on a 500lb hydraulic lift cart from harbor freight. It’s made it much more enjoyable to use. The adjustable work height let’s me cut heavier stuff closer to the ground and lighter stuff up closer to my comfort zone. Plus it already has a big table top to support catch pan.

[@halfnelson6115]

We had one in my high school shop. My teacher had just changed the blade when I got impatient and decided to make the saw cut faster. The blade immediately snapped and my teacher went off on me. He was livid w/me that day.

[@AlbiesProductsOnline]

If you fined a hard spot in a casting drill it using a masonry drill bit just grind the cutting edge to the same as a HSS drill bit and it will last about 1 hole but it works

[@deanharris7149]

Nice.

[@MarionMakarewicz]

Wonderful video. Beautiful job. Great work all around.

[@MegaLostOne]

Weight shouldn't need to be that far forward, it should use the screw hole towards the back more on the bow of the frame. Don't forget to oil through the hole on the large gear that gives access to the oil cup behind it. Someone didn't oil that on mine and the shaft chewed through the bearing and into the cast. I had to repair the cast and make a new shaft for mine as well. Rustoleum hammer tone paint works great and looks really good on stuff like this.

I have some huge prismatic alumin(i)um jaw inserts in the vise (1 cm thick I guess), clamping in screws and bolts was never easier. Sure the inserts get messed up but no need to put nuts on screws or anything. Do recommend.

[@AlbiesProductsOnline]

I live in Australia and I purchased a similar saw and a big bandsaw and I have noticed every saw I see over seas cut on a pull stroke but both of my saw’s cut on a push stroke it is actually impossible to make ether of them cut on a pull stoke trust me I have tried and it will be interesting to see if this saw will do the same I’m typing this before watching the video let’s see 😊

[@jasonbradley7057]

Nice rusteration, love these old powered saws, one question though, is the saw set up correctly? it appears to be using about three inch of blade.

[@JeremyMakesThings]

The stroke isn’t adjustable…so yes.

[@c4t4l4n4]

Great hackjobs for a power hacksaw. One can observe that you have a screwdriver issue. Why use correct flat tips when you can mess up the grooves with undersized/oversized screwdrivers. 🤣

Date code on your motor is 3rd week of February 1953 btw.

Cool! I assume that’s the B(February) 3 (third week) (19)53. I was speculating a little bit on the age of the saw, but assuming the motor and saw were purchased together, that pins it down a bit better.

[@richardgrahame5408]

Would the blade cut better if you reversed around so teeth pointing frontwards. More power in the pushing than the dragging of the blade.

[@JeremyMakesThings]

No, it’s designed to lift off the work on the push stroke and cut on the pull stroke.

[@camillosteuss]

Be more gentle on those hardness testing files... You should just kiss them onto a surface and with light pressure see if they bite, you needn`t move them more than a single millimeter or attempt a cut... If they bite and resist movement at all, the material`s at least somewhat softer than the file, if she tries to scoot around, dont let her, it just ruins the teeth, and increases the amount of force you need to get them to bite if they ever had any intention of so doing with a particular test sample... Stefan or Robin renz gave a nice explanation of this, but yeah, dont file the material down with them, if they wanna bite, thats all the confirmation you need, if you wire brushed the oxide layers off, as scales can be harder than whats beneath... These are file-like instruments, more than they are really metal working tools per se... You dont tighten the micrometer until it digs into the material and leaves a scratch or a dent... The same principle goes here... Minimal force, minimal engagement, maximal efficiency and best readings... Anything else is instrument abuse, as much as the instrument seems to be a round file, if its calibrated, it demands instrument treatment for best practice and best results... All the best and warmest regards! Steuss
