    Hi Simon,

    Following along with interest

    Too wide a belt will reduce the maximum speed that you can obtain with this type of variable speed mechanism. I recall that one of the washing machine manufactures had a problem with belts and spin speeds. I think that they got supplied with belts that were too wide and the machines didn't spin fast enough.

    over the last couple of days I have been scratching my head about the reduced speed range of the mill (mind you it's already better than my current mill but I want it to be running correctly) I have shot off several emails to suppliers in the US including Lagun who made the machine, in 1977 as it turns out.

    They have supplied me with a part number but are not forth coming with actual belt dimensions. They obviously want me to buy their belt for 3 times the price! I'm still awaiting a couple of replies but I suspect the belt is in fact the correct width but not quite long enough. A belt that is too short will run fin inside the rpm envelope but will chop off or truncate both the max and min RPM since the belt does not have the length to run all the way to the end or full diameter of the pulley as either end of the RPM range. This is in fact what is happening. The minimum rpm achieved is about 65 rpm while the max achieved is about 2750 rpm. The specs of the machine indicate it should be doing about 48 - 3750 rpm. That means it's truncating it's min and max rpm by 27%. Too much of a coincidence to me.

    Simon, have you tried talking to specialist belt suppliers like Rydel about the belt, what the number means and what you have?
    They may have a part number decoder that will resolve the issue for you.

    Wouldn't you have the same issue if the belt were too wide? The extra height of the belt would stop the pulleys being able to close right up at either end.

    Hi Michael,

    Yep. I think you are correct but I'm still trying to get my head around it. As in the different consequences of a too wide belt as opposed to a too short belt.

    The person at Lagun said that they got Gates (as in the belt people) to make a special belt for their needs. So I rang Gates direct here in Aus and gave them the Lagun belt part No. but he couldn't help either. I'm thinking if the actual maker of the belt can't help then what hope do I have with another supplier.

    Having said that, I found another supplier in the US who specifically mention a belt part number for the mill I own. Once again it's not the usual belt nomeclature where the belt number includes the with, length, angle etc. It's their own special part number. Anyway, at US$60 it's about 1/2 the peice of Lagun so I may end up getting one from them. I shot them an email to find out more about the belt size, last thing I want is to order this mystery belt only to find it's the same size as the one I have now!

    Michael,

    I just had a bit of a think and also recalled how the belt sat on the pulleys when I was installing it. I do now remember that the pulleys did in fact open far enough apart to allow the belt to sit up against the 40mm shaft. If you recall, I had both pulleys fully apart when installing the belt, to allow max. belt room. So, looking the situation now, it can only be caused by a belt that is too small.

    I think....

    Finally got some further info. Prior to 1994 Lagun used a belt 37.3" long and 1-1/2" inches wide. That's approx. 947mm long and 38mm high. After 1994 it changed to the belt I currently have which is 10x30x900. As I mentioned earlier, my mill was made in 1977 so the belt is too short by about 47mm. The standard belt to fit my machine is a 2322V373 which is a very handy number to know.
    I should be able to source that belt locally.

    Rang several industrial supplies today armed with my new belt number, eager in anticipation for a new belt. However, both places rang back after several hours telling me that a belt that size was not available in Aus and that their records only showed belts that size from OS! ?

    So, I went on ebay and bought one for AU$40 from the US. I actually wanted to buy local but no so.

    Sorry I missed that. I would have suggested F & D O'Conner in Thomastown. Variable Speed Belts - F & D O'Connor Pty Ltd

    They get into weird / harder to find stuff.

    Having said that, if you got out of it for $40 bucks, you would be hard pressed to find it for that price here. On the bright side, the little Aussie battler dollar is doing a bit better than its done in a while.

    Regards Phil.

    Hi Phil,

    That's more that can be said for the UK pound ! It's around 1.10 Euro at the moment, this time last year we were getting 1.40 Euro to the . Since the country decided "Brexit" it has become very much more expensive just to live, not just in the UK but in Europe generally. The government insists that inflation is only around 2.5%, realistically 20% is closer.

    Thanks Phil!

    Actually, I may need that contact in Thomastown. Current state of play is that the ebay seller says that the belt has been delivered (I nominated my shipto address in the US) and shipto say they have not received it! I probably got it delivered direct to me but I'm waiting on a couple of other smaller items to be delivered to shipto and figured I would get them bundled together. I've lodged a customer ticket request so they are now "investigating"

    Next couple of days will see what happens.

    There's a link to them in my post #84 above. End of first sentence.

    Let me know if you end up going that way, and they can get it. There only 5 minutes from me. Wouldn't be a problem to pick it up and on-post it.

    Regards Phil.

    Thanks Phil. Turns out they found my package in the end.

    Well after some trial and error i got the power drive working. Its a Servo Products type 90 power drive. Made in the US about 30 years ago. While they are no longer made, some parts are still available. A helpful supplier of parts in the US emailed me a parts diagram and circuit diagram. These were invaluable in trooble shooting the faulty components on the circuit board.

    In the end, i replaced two SCR (stock items at Jaycar) the 10K speed potetiometer and a resistor. The POT is longer than standard at 75mm and has a rating of 5w meaning the $2 jaycar version is not suitable however i used a jaycar POT in order to get it working before committjng to buyjng the correct parts in the US.

    Since im convinced it can be refurbushed, i ordered about US $35 in parts including new brushes, brush holders and caps, a new speed selector knob and a plastic bottom cover which was missing.

    There are also 3 small bearings which i will replace too. This should bring it back to near new including a nice new paint job.

    Here are the parts waiting assembly. The liitle thing is quite intricate and ill need to hold my tongue right to re-assemble this thing!
