I had a band saw with speed control problems at work, some doall knock off. I finally had the end of my patience with it. Ordered a 1hp 2000rpm brushed dc motor and put a lathe dc speed controller on it, total spend was like $250 on Amazon and let me tell you, screw belts and pulleys. The cuts are always amazing and we can always get the exact speed we need. And the DC motor is so smooth. I put a timing cog bt setup in it to get rid of excessive pulleys.

[@RotarySMP]

Is that a slow speed geared saw, or a high speed saw for wood?

[@briantaylor9266]

My uneducated guess is that when the previous owner that changed the motor to suit European voltage/Hz, they had to monkey around with pulley sizes, belt lengths, and riser blocks to approximate the correct blade speeds.

You could be on to something there. The 50Hz here would lead to speeds 20% lower, all things being equal.

I have the same bandsaw from 1956 without the replacement motor but it is missing the weight system. Thankfully mine only needed a thorough cleaning and proper sized belts so the motor didn't bounce against the bottom. With a little love, these saws are still fantastic after all these years.

[@RotarySMP]

They really are. I think I am catching up on about 50 years of missing maintenance here.

[@Rustinox]

Your electric motor was made ACEC, Charleroi, Belgium, but I suppose you already figured that out. And you're getting close to a fully operational machine now. That's good.

[@RotarySMP]

Hi Michel. It is a really nice heavy iron framed motor. Hopefully just one more video in this series.

[@steveggca]

Interesting to finally see how the variator works, I'm familiar with the torque converters on snowmobiles (centrifical) ,the variators on bridgeport machines (spring +thrust bearing) first time i've seen this setup with the floating center sheave that works with the weight of the motor and the 2 belts . very simple.

[@RotarySMP]

Hi Steve. It is pretty simple, with motor floating vertically, and horizontally to compensate, and the variator also able to self center. Nowadays, it would be a bigger motor and a VF :)

[@steveggca]

@@RotarySMP Just had a look at the current do-all saws ,indeed they do use a VFD with 2, 3, or 5hp motors depending on size. just like woodworking saws they are all welded steel, no more cast iron.

[@RotarySMP]

@@steveggca My DoALL is also primarily a welded steel sheet frame. There are castings for fittings and wheels etc.

[@steveggca]

@@RotarySMP Ah ! woodworking bandsaws moved away from cast iron (ie delta 14" or its 100's of clones) because the frames were too flexible to handle the required saw band tension, the higher the better ,within reason.

The shaft and bearing for your Air Pump appears like an old style automotive water pump rebuild part. I dont know about now but I used to get these from the bearing supplier. They were dirt cheap. You just cut them down to suit the length required. I used to rebuild and make specialist resin metering pumps and used these shafts in them. Just pressed together with gland packing to seal them up. They dont usally like to be disassembled. May I also suggest that If you are going to replace the belts the best style V belt is one with a "Fully Wrapped" construction and not a ground profile. It is very common in large sets of belts but for smaller ones you normally have to request it. They work well with variator as they wear evenly and drive in shallow or deep groves. In Variator's made to suit ground belts you normally find a specialist belt with an easy wearing reinforcement.

[@RotarySMP]

Thanks for the tips. I will have to see what the belt supplier has here. This saw is basically in a retirement village now, and will never see much work in my shop :)

Hello Mark, I had confidence you’d get this sorted out. 👍 Somehow I completely missed seeing the two risers during the livestream; now, it’s obvious they didn’t belong. About squeeze-out of gasket compound: a lovely Cessna 206 crash landed in a neighboring cow pasture some years back, about 3 miles short of the hoped-for runway, due to power loss. It turned out that the crankcase mounted oil cooler had previously been opened up for maintenance, and was resealed on assembly with too much silicone RTV. There was quite a lot of squeeze-out inwards, where it couldn’t be seen, and a glob broke off and migrated to the crankshaft. It lodged in a crank throw and starved a connecting rod. The occupants survived with some injuries but the aircraft was a total loss.

If the motor mount was in the middle hole the air pump may not be hitting the wall? With the correct length of upper belt I suspect you can add an additional stop nut for the highest speed and not have had to cut the threaded bar down?

I still need to go through an recheck it all once the new belts arrive.

[@radioroestig9638]

We had a similar problem with the bandsaw in our workshop, with the belts flying off. The top speed was so high that it just ripped of the adhesive. But since the top speed is basically wood bandsaw levels of speed, we just blocked the metal bandsaw from going that high, and run the rubber belts without adhesive. If people in our workshop need higher blade speeds, they can just go to the woodworkshop anyway and use the bandsaw there

[@RotarySMP]

I use this for both wood and metal, so I really need the whole speed range.

[@gubr]

@@RotarySMP What I see is that you need two saws, swapping the band becomes tiresome, doesn't it ;)

[@mike230224]

The only thing that worried me was the oil around the variator pulleys. I imagine it wouldn't take much to get on the face for it to transfer to the belt and result in some slipping. Looks like you might have gotten a little on the face with the gloves, but it's hard to tell.

Looking at the motor mounts, where they bolt to the machine base, is it possible they have been put in back to front Mark?

[@Oberkaptain]

Hey Mark, you might also be getting speed loss from the motor having a different speed.

[@Oberkaptain]

@@RotarySMP true but that isnt a stock motor and the pulley arrangement may have been changed,

@@Oberkaptaintoo true. This machine has been worked over by an industrial sparky at some point, putting on the safety switching, so maybe they installed that motor then.

[@AndrewMilne2008]

Hi, did you check the actual output speed of the motor, the rating plate suggested 1400, but i could not see if that was in STAR or DELTA, do you know what the orginal motor speed that would have originally fitted to the saw, as that would have given the ranges as shown on the speed plate ??

[@RotarySMP]

It is jumpred for star. The manual doesnt specify a motor, as I guess they were fitted with one to suite the country of the customer. Easy enough to correct speed back with pulley size.

[@charlespetitjean3961]

01:42 I would say belgian, indeed, since the plate states it is originating from Charleroi... 😁

US motors are 1800/3600rpm 1725/3450 for 3 phase so that adds to the fun. Ok I need to go to Vienna to buy hardware by the Kilo. I pay about $3 or so per pound for SAE grade 8 hardware here and metric is higher. Something like that I'll take a pic next time I'm there. No fancy scale though it's weighed on a scale at the register like a grocery store... I wish the US would go to metric hardware and metric for cooking but leave the rest. I also need a supply of metric drill bits and taps as they are more expensive here than SAE even though we use both. My theory is the tool and hardware companies are behind not switching. Force us to buy two sets of tools and stock two ranges of hardware... :) My first choice in belts would be a rubber wrapped belt. A cloth wrapped belt would be too abrasive on those pulleys.

If you have ever had the "pleasure" of doing an inventory , inventory scales have a function where you count out a specific number of what every you are counting, register that and thereafter you can bulk weight the items which is translated into count.

Hi Mel, yeah, variators are pretty much obsolete. Kind of cool though :)

[@melgross]

@ my South Bend FOURTEEN lathe uses one. Reeves drive. I like it because the have a motor that moves the pulley, so you just press a button snd the speed changes. Funny though. I have single phase power for it, so I use a VFD anyway. But as it’s an older motor, as the machine is from the early/mid 1970s, I only use the VFD for phase conversion.

[@RotarySMP]

@@melgross Sounds like the VFD in the Schaublin. Kind of overkill, seeing as I also have the back gear and VFD, but it was easier to just leave it in, and only needed two contactors and two outputs to wire it up.

[@melgross]

@@RotarySMP I just bought an j Terra ring take on a VFD. It’s cheap, from Vevor, though others have it too. It’s a VFD, but there aren’t any adjustments. Connect power and a motor, l,use an air switch and you’re ready to go. No speed adjustments. The 5 Hp version was on sale for just $91, so I ordered one just to play with it. It would be good for older machines I imagine as the frequency is fixed so you can’t run it at low speeds and burn an older motor out. Way cheaper than a rotary converter.

[@RotarySMP]

@@melgross That whole rotary convertor thing is not needed over here. All houses, and most apartments have a 3Ph 400V feed.

Hornbach sells UNC bolts in germany…

[@RotarySMP]

In their stores or just online? There is a Hornbach a half hour from my place, but I dont recall seeing UNC there.

[@gubr]

@@RotarySMP They have like the section for nuts and bolts and in there is the special subsection with special nuts and special bolts and cauter pins and handles and stuff (where you pay by number and not weight, and some are cheap and some are not), and close to the fine threat metric stuff they put some "Zoll" stuff. They have from 1/4" to 1/2" or a bit more UNC in outside and inside hex, even stainless, washers, too. Prices go from not so cheap to premium, but in a pinch it's ok. As for tap and die stuff, I bought an cheapo set years ago at Aldi that had both, nowdays they often come with metric stuff only. Of course I had to buy extra for 1/2" BSW 😏

[@RotarySMP]

@@gubr Bauhaus also has stainless hardware by the peice, and that is crazy expensive. It is located so you see it first :)

3d print the tyres

[@RotarySMP]

Too large for the printer unfortunately.

[@bmalovic]

Hold on... Length of the belt should have nothing to do with ratio/speed. With of belt is other story, cos it will make a difference how deep on this conical pulley will it sit, and according to this will change ratio. Length will just change range of the speed, but on same settings speed should not change.

[@RotarySMP]

Yeah, I didn't express that well. I think I was just moving the used portion of the adjustment range with the different belt lengths. You can see that the longer belt was very loose.

[@thedasroach7743]

I hate it when there's visible grease through my bunghole

[@RotarySMP]

Eat fewer fries :)

[@camillosteuss]

Why do i have a feeling that that motor likes oil instead of grease? It doesn`t really look like a plain bearing(journal b.) setup, but that ball point intake talks oil, while the bottom hole speaks of grease preference... One expects two holes for grease(one for in and the other to force all the shit out of by forcing grease through the first hole) and only 1 for oil(being oil, all the shit and the oil are gonna run down your trouser leg... wait, i meant down the shaft... wait no, that is also fucked up... oh well, you get the point...)... That motor was assembled by a woman - i`m sure of it! There is no way that a normal man made motor can send out so many mixed signals without being wired by an Italian... It just makes no sense... Jokes aside, nice work! Glad to see the old girl getting back into shape... Maybe consider some acetal or similar soft-hard pads as ``damping`` ``bearing`` plates between the motor ``feet`` and the base where it sits... Just to soak up some vibration and make it all a tad smoother... Best regards! Steuss

[@RotarySMP]

Hi Steuss, I was also not sure if it should be grease or oil in there. I am kind of hoping that new belts calm down the motor bouncing a bit, other wise a damper might be in it's future.

[@MatthewTinker-au-pont-blanc]

Those grease nipples look like oilers to me! I hate live feeds: cheers Matthew

[@RotarySMP]

Could well be. I haven't had the end caps off to see whether they are plan or ball bearings.

[@ozzyburrns]

Yeah normally i see those used for oil

[@RotarySMP]

@@ozzyburrns I guess I need to pull a motor bell housing and take a look. I didn't see and wicks inside, which I would have expected for oil.

26:28 Is a “G” Clamp somehow different from a “C” Clamp or are they just called different “in the land down under”? Honestly when I 1st heard ya I went back and listened to it again 2 more times just to make sure I wasn’t hearing things. I know I’ve been surprised before hearing things called differently so now that I think about it, maybe a G clamp might actually kinda make sense too if i consider the thread too …. 🫤 … 😑 … 🙂‍↔️ yeah probably not happening my brain is already set but I will remember to use the local jargon if Im in Australia w/ a pressing need to clamp something …. 😅 or is a “G” clamp actually something completely different and I’m just now only hearing it

[@RotarySMP]

Yep, down under they are definitely G clamps. It would only look like a C clamp if you lost the thread :)

[@milloons2847]

Definitely Belgian: Ateliers de Constructions Electriques de Charleroi. ACEC. They made motors and electrical switch gear also Eexd. Went down with the downfall of the heavy industry in Belgium I guess. The presence of the ACEC brand in this saw is not totally unexpected since it belonged to the Belgian army (ABL marking is the giveaway)

[@RotarySMP]

Thanks for that. I suspected it was from the army there. The Dutch "Noodstop" mod had me thinking Flanders. That is a really heavy cast iron framed motor. Lovely build quality.

Hello Mark, Stefan here, I bought band from a shop here in Sweden that was made from cork, and I must say it works very well, just cut the right length, glue with contact glue and hold it in place with a ratchet band? The thing you hold goods on the trailer with.🥹

[@RotarySMP]

Hi Stefan, I thought the polyeurathane ones are supposed to be the best these days.
