Hi All,

Got a slight problem with my Hobbymat MD64 lathe in that is stopped working yesterday. It was like I hit the stop button but it wouldn't switch on again.

There was no burning smells and the fuse was still good in the plug. Straight away I conceived myself the motor had gone bang.

After an email exchange with Essel Engineering (very helpful) I removed the motor this morning to check the centrifugal switch to discover this is a later model and doesn’t have one fitted.

So out came the multi-meter and I worked my way through the wiring and the 2 relays.

On the photo below, if I pushed in the white centre contact on the lower of 2 blue relays the motor would run.

I’ve check out both relays and they seemed to be working as they should.

Now by luck I was checking the voltage to the on/off switch but my multi-meter was set on ohms/continuity rather than voltage. As I touched one of the terminals on the off switch the lather would fire up and run.

I have now put in a bridge wire from the live terminal too the terminal on the red stop switch as can be seen on the photo below. This is the red wire.

In this condition the lathe works as it should using the on, off and direction buttons.

For obvious reason I don’t want to leave the lathe in this condition, I would rather fix it correctly. Problem is for the life of me I can’t work out what I have bridged/by past. In this condition both relays click in and work and my meter checks tell me the switches are ok.

So now I’m confused so hopefully this is where you step in and say that is so & so

Any help is most appreciated

Cheers

Steve

Thanks all, I'm really glad it wasn't me going mad.. I'm amazed at the wealth of knowledge out there.

I have found the first chuck collet details, which does look Chinese. Looks like hole diameter is set so I will just need to find a cutter of that shank size to fit it.

For the ER style I'm not sure which way to go now. May be buy a ER16 collet and see if it fits or cut my losses and go for a new MT1 collet holder. Problem is there isn't much choice out there for the MT1 stuff, unless some else knows different.

Cheers

Steve

Thanks all for the quick replies.

I'm actually quite please you are having trouble working this out as I've measured them over and over and keep coming up with the same.

Am I right is say a ER collet recess should clip/sit into the holding nut lip? (hope you under stand that)

Also another photo of the holder nut diameter

Hi All,>>

As some of you may know I recently required a Hobbymat MF65 lathe and BFE65 mill.>>

Being very new to the engineer I could do with some help trying to identify what collets I require. At the moment I’m well lost and confused. and not having the manual for the BFE isn't helping either.>>

I have 2 collet holders one that bolts on and one with the Mk1 taper.>>

Below is a selection of photos and measurements I have taken. I believe the collets for the mk1 taper are the wrong ones as they don’t seem to sit in the holder very well.

>>

and the 2nd one,

If someone could be kind enough to let me know what these collets are i.e. 5C, ER etc that would be great.

Kind regards

Steve

Hi all,

Just an update on the process so far. After a lot of web browsing, measuring and confirm my MD65 had a 56mm recess I decided to go for the 80mm HBM chuck from RDG tools. This chuck had recess of 56mm so if the PCD didn’t match all I would have to do is drill 3 new holes. This was the closest chuck I could fine.

The PCD looked pretty close to what I measured about 0.5mm out from the spec on the chuck but being a newbie I wasn’t 100% sure on my measurements.

After some super delivery from RDG the chuck was with me, so time to line it all up.

And if by magic the 3 front mounting holes line up prefect with the standard back plate. I’ve replaced the supply 50mm fixing bolts with some 60mm ones and tighten it up in place. I’ve put a dial gauge on there and the chuck is running true.

I’ve not turned anything yet but will do over the weekend.

So the chuck is a direct replacement for the standard one which is a right result.

So thanks to everyone for the advice, it has been most helpful.

Cheers

Steve

Thanks all,

Some great advice and links there, really helpful.

I should be ok now but any problems I'm sure I'll be posting again.

Hi All,>>

I'm new here so a quick introduction and hopefully a few of you can help out with a bit of advice.>>

I've just acquired back my dad's old Hobbymat MD65 lathe and BFE65 Mill attachment. He gave it away some 15 years ago to a friend of his. This Lathe hasn’t been used since then but is still in good condition, all the slides and bed where covered in oil so they haven’t gone rusty.>>

This has now got a new home in my workshop but I have got a few bits missing. The main one being the chuck! So bit of a problem at the moment. >>

The lathe runs fine, not tried the mill yet but will in due course.>>

So I need to fine a chuck for this, at the moment a 3 jaw will be fine as I will only be doing small turning work. Maybe a 4 at a later date.>>

The original clutch back plate is still on the machine, same as the photo below.

>>

So can anyone recommend a chuck that will fit on this or will I need to change the back plate too?>>

I’ve been looking at the following two, >>

Does anyone know if this will fit ok or have any other recommendations? >>

Any advice is most welcome as I’m a bit out of depth at the moment.>>

Cheers
