I've been busy designing & 3d printing stuff...

[gregsl]

I posted a pic of the Husqvarna Brushcutter case splitter a while ago. Since then I set out to design and print a complete chainsaw "toolkit".

The process has been extremely slow because I have to send the part files out to be printed. This makes it really hard to incorporate changes and print new versions in a timely manner. Unfortunately, the 3d printer I have is an older model and its not capable of printing these parts at the resolution and speed that I'm happy with.

Here's a design mock-up of a semi-complete tool kit. It includes a Carb block off plate, Carb block off plate with hose barb to accept vacuum/pressure pump. Exhaust block off plate, piston support, piston ring compressor, finishing mandrel (scotch-brite Mastermind method), and a Case splitter.



here's a pic of the actual Stihl Case Splitter (for 260) that I picked up from the printer this morning




The Husqvarna Brushcutter case splitter in action. It didnt even flex when i tightened the bolt/split the case




The next toolkit part on my list is an Oil seal puller. I have a mockup done but I am trying to find some hardened metal pliers to use as the jaws instead of having to get some tool steel laser cut into a puller jaw shape.

If there is any interest in purchasing these parts I can custom alter the basic designs to fit whatever model you have. Thing is, it takes a while for them to be printed and even longer to make any required changes and get them printed again. If there is any interest in pre-ordering these kits I could do the required upgrades to my printer and print a whole bunch.

I only have the dimensions for a 260 since its sitting on my bench but I can easily modify the above designs for any chainsaw.

Cool. Can you print me one of those printers? I'll take one.

Ported or non ported ?

 

[boxygen]

Just print me the porting tools, I'll port it myself

 

[Bluefish]

Very cool! Russ

Interesting stuff! We've been discussing getting a printer at work for making production fixtures & tooling, as well as prototypes. I've been learning my way around Autodesk Inventor for the last few months (it was time for the old dog to learn a new trick), so we have the CAD package to design the parts and generate the output files. Naturally I'll make some saw parts if the available materials are suitable.

 

[zogger]

man, is that slick! You should tell the guys here your basic largest outside dimensions that you can print. There's probably a variety of obscure hard to find parts out there where a plastic replacement might work.

The tool set is cool!

Right now I am tapped, but I'll buy something from you eventually.

 

[Bob95065]

You should post the CAD files.

 

[Stihlofadeal64]

wow...I like it!

 

[Rockjock]

If you ever decide to make these for sale let me know.

Sure puts my two HP Indigo presses to shame.

Very cool stuff.

So I've been learning and playing with the printer, and I decided it was time to print something for a chainsaw. I have some plans for things like air filter adapters, as the PETG material seems to have half decent gasoline, oil and ethanol resistance, but those projects all have additional complications. So I decided to whip out something simple. My ported 42cc Craftsman has a larger carb with no purge bulb port, so I just cut off an old bulb and filled it RTV - but I thought maybe I'd print a block off instead.

Like anything else you need to design for the process, and things like how you orient the part during printing are important. And of course first you have to draw it - this part is simple:

However, the 3D printer makes the part by drawing a thin string of hot plastic and building that up layer by layer. The surface finish is pretty lame - good from far but far from good. Here's the part, printed on medium resolution (it took 25min to print):


Here is my RTV part and the printed one:





It's OK - I'm still deciding if I like it better or not. From a functional point of view, it would be better if I just made a plug to mount into and seal the hole in the recoil cover, which I probably will do.

PM sent, Im interested in the tools for vac and pressure testing and also a case splitter.

 

[jughead500]

Cool beans.I see where the rest of my retirements going.lol

 

[Marshy]

I might as well ask my questions here so everyone else can gain from them as well...

Will the block-off plates of case splitter be specific for a given make and model or will they be universal and work for a group of models for a given maker?

Do you need us to provide you measurements for the saw we intend to use them on?

 

[Chris-PA]

Just making sure it's clear I'm not the OP in this thread - I just put my small project here as I thought it was on topic.

I have two saws I'd like to make an air filter adapter for, but it's a PITA project. First I have to find a filter that I think would work, either one that fits under the cover or I'd have to cut a hole in it. On one I'd have to come up with some way to hold the rest of the cover on without the filter cover nut. And then, all the angles and sizes and shapes of parts are obscure, which makes drawing it a real project. But I've been keeping my eye open for appropriately sized air filters from common mowers and such.

BUMP
Interested in 3D printed items as well.
Why let a great thread die!?

 

[jackjcc]

The pressure test plates are very interesting to me. Would buy.

The future is endless.
