That's for sure! Briggs only sell full sheets unfortunately but it's given me lots extra to match some speakers to the turntable.

In the end I've gone the DIY path. I've bought a trim router to try and get a good edge on the veneer and after much reading have decided to go with PVA and clamps as the gluing method.

I bought...

I have a vintage turntable project that I am looking to upgrade with some quality timber veneer. I can easily break down the turntable so it is basically a particle board rectangle with a few holes...

I actually have updates!

I ended up going down the PWM drive path, mainly because it was $200 delivered and I could use the existing motor.

Step 1 was to get a fan that would blow air into the...

Thanks all. Search continues. Will see if I can find a local place for motors near/around Penrith NSW.

Great info, thanks Bob. Just heard back on that motor on gumtree. It's 400mm x 280mm diameter, that sounds huge for a 3HP motor doesn't it?

No way can I fit that on the mount unfortunately

Still plenty of go at 1.5hp, especially vs what I have on there at the moment which is 0.5hp and probably only 0.15 of those left and working properly ;)

What are the pitfalls in looking for...

Thanks cba, very helpful. Will grab a motor and then size the VFD from there.

Ok, on the look out for 3ph stuff now to see how that would pan out. Made an offer on that motor and waiting to hear back. Pricing up the DC motor drive and it's the same as a 3HP VFD delivered.
...

Got it. Thanks Bob.

400v, don't I need 240v?

Everyone talks about cheap 3ph motors but I've never found one for less than a hundred plus.

I don't disagree cba, but I don't have the budget at the moment for a 3 phase motor and VFD, whereas I currently have all I need to get the DC motor running, bar the PWM.

Is there another PWM you...

New plan. Turns out the lead I had to replace the board wants $250 for it, maybe not.

For that price I can buy a KB Electronics DC motor controller which will let me use a pot on it and get total...

I will take my chastising as its due. Appreciate the comcern though.

Cheers Simon, appreciate the help. I've been in contact with a treadmill repairer in Penrith who may have a replacement controller board.

If not I will let you know and see if you have something...

I'm really annoyed with myself. After receiving all the necessary parts to build my new box, building the box, chasing out the lid to incorporate the control board and speed indicator leds... I...

I've found the gal gives off a nasty vapour if welded plus can make the electrode fizz.

I would strongly recommend grinding it off.

Parts ordered, plan is to redesign the control box, a little larger so I can include the control unit for the motor.

Also ordered a few fans so I can try and get the cooing right once I get the...

Will do, watch this space as I've ordered a larger control box and will look to incorporate the control buttons and leds.

True.

Dunno. I was going to run it and see what happens. Worst case I make a replacement.

My motor looks like the brushes are 90 degrees, plus reversing the polarity works fine. Problem is the attached fan which now works great for sucking air out of the motor, not pushing air in.

This is probably getting a little beyond my abilities. Plus the original board works a treat and has speed indicator leds.

I think I will rework/make my control box and include the board as the...

Cheers Ew. I will keep an eye on that. Just run the motor on the bench with no cooling and it didn't even get warm after 2 mins on 20% power. No idea how that will translate in the real world though....

Looking at the back of the board there is a common connection between all the switches (up, down, off). Would that correspond to the ground on the pot?

If so what's the risk of I get the other 2...

Interesting. Maybe the pots not completely out yet then. I assume I have no need for power if I replace the board with the pot?

Eg remove the red/black (if they are power for the board) and work...

Yeah I does go straight to the display.

Got it NCArcher. Looks like I need to incorporate the button module into my control box then.

I will check where the wiring goes for the hall sensor too. If it goes to the display can I assume...

Thought that might be the case. I assume it varies voltage to maintain speed.

Now to the questions.

1) There is a Hall effect sensor that connects to the PWM. What is this for and should I look to keep it?

2) This is the speed control module. I am keen to remove this and...

Great day for the Hercus today, not only did I finally get all my imperial gears (big thanks to pipeclay) but I took a gamble on an eBay auction for a treadmill:
...

So today I managed to steal a few moments to put my cheapie eBay switches etc into my equally cheap eBay waterproof box.

It is designed to control a VFD setup once I get a 3 phase motor. I wanted...

I'll do that, cheers Ueee

Thanks hornet, I knew the edge was for relief which was why I was asking if it was a problem putting it hard up against that edge as that would effectively remove the relief on one side and make it...

Thanks Ben, appreciate the offer of help on the t nut.

What's scary about parting off on a hercus?

Despite still needing to get a few critical parts (rest of the gears off pipeclay, tailstock clamping arm, a few other bits) the last of my critical parts came in today from CDCO. Playing around for...

Thanks Ueee, seems like your back gear clearance is way more than mine. I will see how mine goes for the short term and look to move to a better location once I can think of a better mounting...

Thanks Ewan. I can see the magnet but not where the pickup is located. What lathe is that? Is it a Hercus 9"?

Setup looks a bit similar to mine with the belts etc.

Any pics of how you mounted it? I looked at the bull gear but there didn't look like there was enough room.

First & second one I did pipeclay, as I mounted it sufficiently far out the it would fit a 6" chuck too. Plus magnets are easy to come by so I was going to fit another magnet to a 3 jaw in time.
...

I've been collecting stuff for a future VFD mod and wanted to also add an RPM sensor to the lathe too. Bought some cheapies off eBay so that I could test the concept and replace as they failed or...

Thanks jhovel. Got all the bits at the moment so will pop it into the housing when I get it, didn't think about EMF so hopefully that's not a problem.

Very interesting read. I've been collecting parts for a much simpler control box for when I convert my lathe to VFD. Using cheap parts from eBay to just test the concept first. Only have RPM display,...

I looked here for a part number after measuring the pulley to pulley distance:

http://www.goodyearep.com/ProductsDetail.aspx?id=3128

Mine was 46" so I opted for the 6PK1170 as 6 ribs was just...

Awesome! Thanks.

Do I have to engage the half nuts and then snug them up or does it not matter?

I highly suspect the half nuts are probably worn, everything else on this lathe is and give its age that's not a huge...

Thanks pipeclay, I will probably take you up on that offer, just need to build the toy fund back up a little as it's taken a hammering recently and so I'm a little in the red ;)

I managed to get...

Thanks to a forum member off this site I received a load of the missing gears today at work. Not all of them have been acquired yet but I have enough to be able to connect up the lead screw and have...

Cool. Pics are always good :)
