Hi all,

Would anyone be able to tell me what speed I should run a 180mm diameter wobble saw at in the spindle moulder?

Thanks

Murray
 
If I was you I'd run as fast as possible with a wobble saw in a sindle moulder, the mere thought makes me shudder.
Rich.
 
Ive used an omas 6" in a spindle moulder and used it at around 4000,about the same as a tablesaw/radial arm.I think the recommended max speed was 6000.I,d run it at 3500 if the sm lets you.
 
I also have the Omas 6" wobble saw and run it at 6000 in my spindle as it only has one speed, its the max stated on the blade but I don't get any vibration. About 4500 should be the max on a 8" one.

Rich, whats the problem with running a wobble saw in a spindle moulder, its what they are made for? Far better than running a Dado set in a table saw.

Hi Jason, I'm obviously talking out of my backside, Iv'e never seen a wobble saw let alone a spindle moulder, please forgive my ignorance, nonetheless the thought of a saw that wobbles fills me with dread, how on earth does one keep the workpiece safe whilst passing it through a saw that "wobbles".
Regards, Rich.
 
The saw blade is clamped between two substantial tapered washers, by rotating one washer in relation to the other the blade is set at an angle to the spindle axis which makes it look like it is wobbling.

The amont of wobble is adjustable so the more the blade runs out of true the wider the kerf or slot it makes. Think of it like a larger adjustable version of a slitting cutter in a router table as long as you use the correct shaw guards its a very good way of creating grooves in timber.

It's also sometimes called a drunken saw :wink:

Hi Jason, thanks for the explanation, is there a thread or link that you know of where I might see one in action?
Sounds to me like it could do the same job as a dado cutter, is there any video links you might know of where I could see one in action?
Regards, Rich.
 
Thanks jason,

I have tried running it at 6000 seems ok. 8000 vibrated too much!
I think I'll try a lower speed as well.

The wobble saw itself is of unknown make but is brand new. I just cant believe it doesn't have a max and min speed stamped on it!

thanks again

I did loo on youtube but could not see anything, here is a diagramme of how they work. If you had asked yesterday I was using mine and could have got someone to video it in action, make squick work of grooving door styles & rails for panels.

DO NOT think that these can safely be used in a table saw, the center boss is about double the width of a dado set so you would need a very long arbour and its also harder to see the edge of the spinning blade.

Hi Murray
I have a three-speed spindle but run my wobble-saw (7" or 8") at the slowest speed (4000revs).

Jason, thanks for that, now I can see what you mean.Thanks for the education, it has not been wasted.
Regards, Rich.
 
Every time somebody mentions Spindle Moulders I get an attack of nerves.
We had one where I served my time, and in those days cutter blocks apparently didn't exist. The cutter was double sided and passed through a rectangular hole in the shaft and was secured? by a bolt and locknut.
Hanging on the wall behind the machine was a brown Cow gown with the arms spread out and a large hole in back and front where the cutter that had come loose and entered and left!
Amazingly the wearer had got away with a slight graze on his right side!
It was a sobering reminder to make sure the cutter was tight.

French cutters, now banned by the Health and Safety overweening NUTCASES!
 
Have you ever had anything to do with them Jake? I have and I have to agree. I lost a finger in a plastic moulding M/C and the H&S were called in. Bright young fellah, looks at one of the other machines, asks questions to demonstrate that 'Book Larnin is Wunnerful Thing' and tells me he wants the chute where the components drop out blocked.
I patiently explained that that was only a hazard if you were to lay on your back and push your hands up between the moving dies and that blocking the chute would completely stop all production.
His reply? 'Not my problem, I want it blocked!'
I refused. He was staggered that someone would have such effontry and was stuck for words, but finally managed to stutter, 'Are you refusing?'
I said yes, and told him to give me his order in writing and I would give my refusal in writing.
He stormed off and sent his boss to see me and I told him the fellah was a P**t.
He replied, 'He's young'. I said he was a Young P**t!
that was the end of that!

Every home should have one.
 
NOW I know why your handle is "Digit" you dark horse you,
Regards, Rich.
 
Thanks Malcolm, I think I should try it on a lower speed like you suggest.

Roy, I must admit this is the first time I have used a wobble saw, but to me it is just a different type of cutter. Still dangerous and very willing to eat a finger if you give it the chance!
Most of my experience centres around rebate blocks adjustable groovers and a pair of 250 mm dia tenoning blocks etc. I feel very comfortable using them, because I know I have set the machine up properly and the blocks are up to standard. I wouldn't go near one of those french heads with a barge pole!!!
I think H&S have the ability to do some stupid things but banning them probably wasn't one of them!

Thanks for the advice guys,

Murray
 
They were a pretty dreadful idea alright Murray, and even the H&S must get somethings right on occasion.
The compensation helped me buy my first house Rich so I simply had to learn to pick my nose with another finger! :lol:

Roy.
 
Roy, Russ Conway didn't do to bad, :wink: :wink: :wink:
Rich.
PS. Mind you, personally Iv'e never sat sidesaddle.
 
No, I haven't, but I have had a cutter fly about a foot past my ear from a non-pinned pre-"euro" safety block. I think the H&S stuff has improved things massively since then, never mind square blocks, french cutters, macho holes in aprons, etc.
 
Like I said Jake, even they can somethings right, but I ran up against them whilst I was self employed, and their bullying tactics went on for 7 months before I forced to back down.
I don't like bullys, whether official or unofficial.

Roy.
