Great set of videos, very interesting, keep up the good work

Amazing restoration! With current supply chain issues, shortages and empty shelves, the knowledge of how to fix what you have becomes more and more useful. Thank you for sharing!

[@elwellboy]

Glad you enjoyed the video. With a little TLC, these older machines have a lot of life in them. Thanks for watching and commenting.

Very much enjoyed your videos. I just finished checking out my 1963 Unisaw and re calibrating the stops for 90 and 45 degrees. My saw has a LARGE, 10' outfeed table built around it and necessitated removing the top and leaving the wings attached to the outfeed table. This caused a real problem when it came to reassembling the top on the saw. I just couldn't get the holes lined up. After a number of hours fiddling and getting nowhere, I decided a successful tactic might be to get four 3" 7/16ths fine tread bolts to make into alignment pins. I cut off the hex heads on a metal cutting horizontal bandsaw, chucked the threaded end into a half inch drill and pulled out an angle grinder, which I placed on a work table with disc up. Starting the grinder and running the drill with the cut off bolt spinning against the grinder at a modest angle quickly produced a perfect pencil point on the end of the bold. I installed the modified bolts into the top finger tight and took it to the saw-- a little push here and there and the top seated perfectly.

Glad you enjoyed the video. Sounds like a great set up you have for your Unisaw. Your fix sounds like a lot of work but certainly effective. Next time you'll have everything ready to go. Glad you have it back and going. Thanks for watching and commenting.

I've started the restoration of my Unisaw from the 70s so this gave me some good tips. Awesome saw! Thanks for sharing.

[@elwellboy]

Glad you enjoyed it. Good luck with your restoration. These old saws are workhorses and a pleasure to use. Thanks for watching and commenting.

nice work! good series.

[@elwellboy]

Glad you enjoyed it. I love using that Unisaw. Thanks for watching and commenting.

[@mrneil962]

Hey, thank you for making these videos. I have an early 80's model but not much had changed. I appreciate your tips for reassembly!

[@elwellboy]

Glad you found it helpful. These are great saws and will last a lifetime. My kids will probably have this one someday. haha Thanks for watching and commenting.

[@docdevin1]

About to start on a 1966 model. Thanks for the video and the encouragement.

[@elwellboy]

Glad you found it helpful. Good luck on your restoration. Let me know how it goes. Thanks for watching and commenting.

[@ErickUtley]

That was fun... Thanks for taking the time to make the videos. Keep up the good work, oh and the paint looked Great! Ready for another 100 years of hard work.

[@elwellboy]

Glad you enjoyed it. I have enjoyed renovating these old Delta Rockwell machines. Thanks for watching and commenting.

[@richardc6932]

I have a 34-450 Rockwell Unisaw that I have not been successful in dating. Rectangular red manufacturer’s label on the upper right front just above the old switch location. Handles on both adjustment wheels are black plastic not polished steel. It has a large vertical Rockwell spelled out on the centre os the clean-out door. I would love to find the original splitter assembly that protrudes through the throat plate (not one that came on some on the rear of the saw) , my saw came with a humongous motor and two belts. I really enjoyed your whole restoration procedure, brings back memories of my restoration.

[@elwellboy]

Glad you enjoyed the video. These vintage Unisaws are great machines. Check out the following link to match your serial number to date of manufacture. wiki.vintagemachinery.org/DeltaSerialNumbers.ashx I'm not 100% sure but I don't believe the older Unisaws had a splitter that attached to the arbor assembly. Good luck. Hope this was helpful. Thanks for watching and commenting.

[@henrymostert2125]

Great restoration job. Watched beginning to end. Question what color or paint did you spray with. Also it would be good to know what you paid for a basket case. This would help people to see if it's worth the effort to do a restoration. Anyway it looked supper

[@elwellboy]

Glad you enjoyed the video. I used Rustoleum Dark Machine Gray. Home Depot carries it. I picked up this saw for $250. While it was pretty rough looking nothing was broken and it now runs awesome. Thanks for watching and commenting.

[@wajih9219]

Great work! I believe it was part 3 you showed a piece of sheet metal you were going to mount on the right side to stop dust from flying out. I’m guessing you noticed the motor protrudes out the side of the cabinet so a flat sheet couldn’t work. Was wondering what you did for that large side opening?

[@elwellboy]

I fabricated a box from some 1/4" plywood that hangs on the side of the cabinet and covers the motor. The top is slanted so sawdust doesn't collect. It hangs a couple sheet metal screws in the side of the cabinet. I took a picture but can't insert here. It's about 6" deep and just wide/high enough to cover the opening. Works great. Thanks for watching and commenting.

[@markrosier6889]

Thanks for the update on the Unisaw. Mine was an inheritance from my grandfather, vintage about 1948. Seems to run great but overloads my house curret 120. As I understand it, the saw can run, maybe evern better, with a 240. So my problem is to know which wires in the on/off switch I need to change. Is this safe? Don't think the motor has been rewired from the original but it hasn't been used much, though it has been used a little and seems fine, since 1977.

[@elwellboy]

The wiring change you need to make to convert back to 220V is the motor - not the switch. Most all have a small diagram on the motor housing or inside cover of the wiring box. The old saws can be hard to tell wire colors as they might fade over time. If you can find that it is an easy change. If you can't find that diagram, I'd suggest consulting an electric shop. You don't want to cook the motor. They run alot better on 220. Hope this helps. Thanks for watching and commenting.

[@jongkeum]

Thanks much for uploading this video. It really helps my restoration project. By the way what's the model and HP of the motor? I've seen a lot of Unisaw motors so far but your's is new to me. Thanks again!

[@elwellboy]

Glad you enjoyed the video. The motor is branded Delta Rockwell, model # 83-611, 1.5 HP manufactured by Marathon Electric. Good luck with your restoration. Thanks for watching and commenting.

[@n6408s]

Do you recall what bearings you used for the arbor? Mine look like 6203LB, but those are sealed only on one side.

[@elwellboy]

I used Vista 6203-2Z bearings. Search Amazon for - 6203-2Z bearing. You'll find many available. Hope that helps. Thanks for watching and commenting.

[@shawnbrown2179]

Great Video! Where was it that you purchased your replacement belt from for this project?

[@elwellboy]

Glad you enjoyed the video. I got the belts from Biedlers. Here is the link. www.biedlers-belts.com/ Thanks for watching and commenting.

[@shawnbrown2179]

@@elwellboy Thanks, I am working on restoring a Model 34-405 from 1950.

[@elwellboy]

Shawn Brown fun project- good luck. Let me know how it turns out

[@KaliBlaz]

great project, but i would get rid of the railings and get biesemeyer fence system instead.

[@elwellboy]

Glad you enjoyed the video. I've thought about getting a Biesemeyer but haven't pulled the trigger. Thanks for watching and commenting.

[@hofzer]

How many hours would you say you had into this project? Thanks for the videos.

[@elwellboy]

Hard to say as I didn't really do it all at once but I would guess maybe 20 hours total. Hope the videos were helpful. Thanks for watching and commenting.

[@taybeemad]

@@elwellboy Have just about the same saw. After watching this I will redo mine as well.

[@grobertson2008]

I just bought the same table saw and want to do the same. Would love to be able to ask you question when I tear it down.

[@elwellboy]

That is a great saw. I have really been using mine. No problem. Let me know if you have questions. Good luck on the restoration. Thanks for watching and commenting.

[@grobertson2008]

@@elwellboy thank you for helping. Have an issue getting the interior parts out. In your video you start to remove, and then it skips to the parts being out. Any suggestion?

[@elwellboy]

Once I got the big pin holding the blade arbor out (it was really frozen), I tried to remove the raising and tilting mechanism without removing the screw rods. I couldn't get them out so removed both screw rods and was then able to get the mechanisms out (it was still tight). Hope this helps. Let me know how you make out. If you want shoot me a text at 908-969-1517.

[@grobertson2008]

@@elwellboy thanks a lot and thanks for your number.

[@philipyourno7540]

Any info for a good vfd for a conversion to single phase?

[@elwellboy]

Unfortunately my knowledge base for 3 Phase to single phase is almost non-existant. I have seen stuff on how to do the conversion but have never done one. As you probably know there is a lot of vintage equipment with 3 Phase. Thanks for watching and commenting.

[@ryananthony4840]

Can you get replica Delta plate and nameplate? I'm looking at buying one rt now

[@elwellboy]

You might find something on eBay. Or, check out vintagemachinery.org. You might have to click around there a bit but there is a lot of Delta Rockwell info. there. Good luck. Thanks for watching and commenting.

[@87_North]

Hi there - I have the same model Unisaw (34-450, from 1965) and plan to start restoring it next month! Got it on an auction for only $150.. this video is a ton of help! Any chance I can get your e-mail if I have any questions? Thanks!

[@elwellboy]

Very nice - $150 is a good deal for that saw. Glad you found the video helpful. [e-mail] Let me know if i can help out. Thanks for watching and commenting.

[@reed1541]

Do you happen to have a link or the correct spelling for Beaglers?

[@ryananthony4840]

Maybe the nickels wouldn't fall if the machine was set on a rubber mat?

[@elwellboy]

Perhaps but really the only point of the "nickel test" is to simply show how stable these machines are when they are working properly.
