Thread: Old belt driven Woden grinder

I know nothing of these so can't help but do you think the twin pulley is a modification and it originally had two wheels? It looks like it was cast to have two tool rests so two wheels and maybe driven by a rear driven flat belt through the center?

Thanks Burnsy, you are right. The large pulley wheel looks like it has been added many years after its manufacture to convert the flat leather belt drive system to vee belt via the emmco electric motor. There would have been another grinding wheel where the pulley wheel is now. Looking back at my original post it is a bit ambiguous so I have reworded it to 'flat belt driven grinder'.

Anybody else have any info about the manufacturer Woden or the time period it comes from??

I couldn't find anything specifically on the grinder, but I believe this is the company

Thanks for your research Camoz.

I did have a brief look at the The Steel Nut & Joseph Hampton Ltd company on one of my searches but I couldn't find any references to their manufacture of my grinder.

Then when I had a second look at this company after reading your reply I noticed a link to a 1927 Woden tools catalogue in the first website you listed. This catalogue lists the grinder (apparently it was called a polishing machine) and even has a picture of it. It seems I just didn't have a proper look in the first place. Thanks again.

Looks like who ever converted it was a bit of a visionary and had already realized the benefits of slow speed grinders.

Twosheds,

Glad you found something on it, it's not always easy to locate information, especially for items the company didn't specialise in. Now all you need to do is find that cast stand to go under it

We haven't seen the pulley coming off the motor yet

True, but if the pulley is attached to a 1/4hp 1425rpm motor and isn't visible in the pic then I guess there is a fair step down in rpm.

Perhaps it is gigantic, and spoked.....OK I'll admit it, I just want to see a picture of the full motor. Twosheds, if you get a chance, I am interested in seeing a shot of the full motor (Couldn't find much on early Emmco Orange NSW)

Hi mobyturns and camoz

I would dearly love to find the stand but I think I would have buckleys. However I will start scrounging through the scrap heaps on neighbouring properties when I am back out there for harvest next month. Never know what will turn up.

I took a few piccies of the emmco motor next to the Woden grinder for comparison.

The pulley wheel on the emmco is 60mm outside diameter while the pulley wheel on the Woden is 420mm outside diameter. Good to see a little bit of reduction in rpm there.

The old grinding wheel is 350mm diameter and the whole thing must weigh upwards of 60kg. It was a heavy bugga to lift into and out of my ute.

Haven't tried the motor yet, there is a slight problem with the power cord. However I am toying with the idea of now using the grinder rather than just prettying it up for decoration in the shed. The grinder shaft turns as smooth as silk, not bad for a 50+ year old machine.

I was interested in the mention of "Stauffer (grease) lubricators" ... which were on the 12" jointer I have yet to make any sort of progress with.
A couple of links ... not sure "plain bearings, small loads, slow speeds" applies to the jointer ... :/
Cheers,

Thanks for the link Paul. When I was having a bit of a fiddle with the grinder I noticed the lid of the grease containers had much longer threads than I expected, I did think to myself at the time it was a little strange. It never occurred to me that a turn of the lid will force a small amount of grease onto the shaft. Just shows how little I know about these older machines.

I remember we had an old cement mixer on the farm that had these screw on grease caps. Long fine thread and some knurling around the top of the cap so you could fill the cap with grease and give it a turn or two by hand to force some more grease in every so often.

Well then thank *you*.
I was wondering how the hell they worked, filled with viscous grease.
