That might explain the couple of strange bits of metal that came with the machine?
The machine is going nowhere after the following "incident".
While we were assembling it a couple of the old timers put the (25+kg) cast iron gearbox to the feed roller onto a large wheeled work bench.
The gearbox has a large (~10" diameter) spoked cast iron flat belt pulley on one side and large gears on the other side.
Instead of putting the gearbox down on a flat side or a side with the gears they put it down so that the edge of the pulley was resting on the bench.
Then someone decide to move the workbench and the gear box rolled off the bench and landed on the pulley shattering the spokes into half a dozen pieces.
It could be welded but I have hidden the bits in case some one does this as it would be WAAAY too dangerous.
Instead I will have to make a suitable pulley.
While Im at it I might convert it to a V belt system
The cutter cover is woefully inadequate and will need to be completely rebuilt
There are no guards to the belts . . . . . . etc
We are currently wrestling with two old iltalian combo machines. One is a solid old SMC machine with a 10" planer/thicknesser and the other is an equally solid 12".
Both machines have checked out fine electrically, but there's a fair bit of surface rust and everything mechanical is stiff and they need some serious TLC.
I'm working on these from time to time when I get a few spare moments and there is another guy who's spends his 4 hours a week of shed attendance on these machines. The rate of restoration is very slow, not made any easier by a lack of necessary tools. Last friday I had to go home to get spanners big enough to remove the saw blades. Last week I had to go home to get a 20 mm tap, etc.
We have one fella who is really talented with MW machine (he rescued a small Myford MW lathe from a skip and completely rebuilt it) and he's made new aluminium guards for the planer operation of these machines but we still need guards and dust ports for the planer and thicknesser side of operations.
I'd like to be spending more time on these old machines but I've been flat out doing electrical (replacing switches and rewiring stuff), plumbing (water cooler and water boiler etc) plus safety stuff like making and putting up safety signs.
What I should do is take some photos of the gear so you can all see what we are dealing with.

some housekeeping
I would love to think that the blokes working on this machine know they are on solid ground, and know that some wild and outrageous claims about the legality of the old machine should be ignored. And since kuffy could not produce the relevant Australian standard I obtained a copy.
I read it, and did some more reading to confirm what I knew was true, since I have been involved in actually giving input into an Australian Standard.
What it says must be read with a clear understanding of what a non mandated Australian Standard is, and what enforceable mandated standards are.

So....until I have someone show me where the laws banning square head machines are, I'm happy with what I know to be true...
The use of a square head machine in Australia is not banned
Manufacturing square head machines and parts for them in Australia is not banned.
Selling new or secondhand square head machines is not banned.
Squareheads fighting in cages in Victoria is not banned.
Teaching the use of square head machines in TAFE and other places is also not banned.
Here are 52 RTOs approved to deliver this unit of competency.

This is my last post in this thread.
Since I would love to talk more about vintage square head machines, I'll zip across to the vintage machinery section and discuss it with like minded individuals.
Cheers,
Peter<!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <woNotOptimizeForBrowser/> </w:WordDocument> </xml><![endif]-->

AS 1473.6-2005 (which is still the current one to my knowledge). whether the crap this document says is "law" or not, damned if i know. I just know what i was told in school. perhaps ive been trained by teachers spreading myths..Im perfectly happy to concede that older machinery produced before standards or laws are passed aren't always banned outright, i dont know for sure, but it seems reasonable and Peter ill take your word on it. also, thankyou for schooling me on the fact that standards arent always enforceable laws, more like guidelines.
for thicknessers and surface planers and also combo machines, the standard says from memory going back +10years, something about cutterblocks must be a cylinder shape. and then it will crap on about how the knives must be fully supported/clamped and not protrude the cutterblock more than about 1.5mm, or 3mm for 20inch+ thicknessers. there is also something about how far away the clamping wedge can be from the cutting edge, i dont know the measurement but i reckon it gives an exact measurement in it. theres probably other stuff in it, but i dont remember, didnt really care.
now..you may ask, whats so important about any of those design "guidelines" (guidelines, because not all standards are laws i just found out). there all based around limiting the amount of exposed cutter. if you had a cylinder head, with a cutter exposed only 0.5mm from the cutterblock. each revolution of the head can at maximum only take 0.5mm from your finger (ignoring any depth gained from the distance from the clamping wedge), because to be able to take anymore, you need to be able to physically shove your finger into the actual steel cutterblock. all this is a more fancy way of saying "Square heads were outlawed a long time ago due to the amount of trauma suffered if u did touch the spinning head." though i probably shouldnt have said "outlawed" as it obviously struck a nerve with Peter
for a square head, lets say 100mm square head, the comparable cylinder head will be about 141mm in diameter. on a cylinder head with just a cylinder and a cutter sticking out of it 3mm, no clamping wedge etc, you will lose 3mm slices off your finger, arm, face w/e per pass of each knife. on the comparable square head, off the top of my head, its gonna be closer to about 23mm taken per pass of each knife.
in summary,
square heads are not "illegal"
square heads are extremely much more dangerous for the dummies that actually touch spinning cutter. difference of losing a fingertip or hand...
I would be willing to use square heads on anything, buzzers, thickys, spindle moulders w/e. wouldnt worry me in the least. i have used machinery which far exceeds the dangers from square heads. i would not purchase a square head machine for commercial use, just seems like a lawsuit waiting to happen.

You'se can all rest a bit easier.
Following a risk assessment of all the machinery machinery in our shed we have decided to locate Tom "off site" and restrict access to a very small number of members.
