As promised - more detail is available - the project is approximately 200 pages. So I have uploaded a chapter on an insight into Elmer's Wobbler from my project. If you would like to see any other aspect of this project, please have a look at the table of contents also uploaded. If requested...

Cheers Brian Is there any particular type of steel, brass or aluminum that I should be comparing e.g alloy 2007 aluminim etc?

Previous to this thread, whilst I was searching through other threads - I came across a table; I believe this was like a material comparison table. But I cannot seem to find it now

any particular reason as to why those materials?

Hello Guys, Was wondering if anybody had any information concerning material selection for the wobbler components? Gary - nice wobbler mate.

Oh! My tutor has just specified what exactly you mean - I guess I'll have to get back to it after the Holidays! Cheers for the heads up Prop. Enjoy your Christmas everybody!

Perhaps its the CAD Platform I am using potrays this differently? Solidworks. I have ensured the countrebore is on the opposite side to cylinder.

Cheers Thayer - I have ammended this on my report

CAD so far - I was thinking of having a vertical osilliator - I have found some designs for this on the net. Or perhaps I could scale Elmer's units up to the nearest whole figure. Next step (re-egineering) During my CAD, I noticed the Shaft Bush was slightly over, I had to reduce the...

Cheers prop

Is this right?

So - by the time the cyclinder port has reached the exhaust port the cyclinder should be fully compressed with air - ready to dispense the air, and by the time the cyclinder port has reached the intake port the piston should have no compressed air - ready to get air compressed back in...

At this exact moment I am writing about Elmer's Wobbler, currently explaing the oscilliating movement. I was wondering is this all that needs to be mentioned in relation to operation. As I believe bore stroke and performance, belong to 'calculations' rather than 'operation' - perhaps the...

Tin they look amazing! In relation to 're-engineering', I would like to keep to Elmer's design style. However I will be changing dimensions and adding tolerances (this i beleive to be thr tricky part - as if wrong, then the operation of the wobbler would fail). But - yes. I will be taking...

Randy, I'll be following your progress! So far, I'm really impressed!

Cheers Randy - that makes perfect sense now. I should be able to get at least four hours of CAD in on Thursday. I'll be sure to amend this mistake.

Don't worry, I'm conscious that being a second year apprentice, I have only the one day at college and the four other days are at my work placement; which requires me to learn six-sigma problem solving principles, along with lean techniques and various projects. As far as machining goes, I'm...

Thayer, I have had a quick browse through this thread, and am impressed yet confuse; due to the high calibre of this project. Of course I cannot offer any advice, as I am yet a 'blank canvass' in relation to maching. Hopefully by following HMEM - I'll be able to learn and indulge on a craft...

Guys - I was also wondering, why does it seems extremely hard to find any information on Elmer Verburg himself? If I typed a celebrity on google - wiki would have the last place they dined at! I believe doing some background reading on Mr. Elmer Verburg would be beneficial for my project...

Cheers Tin, I think Monday I'll have a look into the titles you have mentioned. Weez - I'm not entirely sure what you mean? On the engineering designs it specifies a locating pin should this fit on the opposite side to how I have shown in my CAD? In simple terms - IT'S THE WRONG WAY ROUND...
