090G rim sprocket! pics!

I have been working on this for quite some time!(way to much)
I want it for my milling purposes. and to have if I want, to run different size chains and rims.

Looks good! Awesome work.

My buddy is a mech. engineer, who has helped me communicate with the drafter, and machinist!
Talk about a lot of detail!(carbon mold(s) epd machining, broaching, burning, hardening, and the list goes on!) A good learning experience! Hopefully with the long week end I can tear into it, and give the prototype a real work out in some knotty pin oak, then some huge beech I have in the pile! But it will be worth it! At least for me!

Now that's sweet!

That's a great looking piece. I know quite a few guys who will be wanting one of those for their 090Gs.

Wouldn't mind one myself. I made one up for an 041G which was much less effort. I had allusions of doing the same for the 090G. Unfortunately, I ran out of gas. Kudos to Teddy.Scout and his partners.

That looks REALLY good. Did you start with a original gear or is that all from raw stock?

I don't have the exact steel name, but it is all new from tool steel, that we are able to get it to around 58-60+ rockwell strength. Finished with the fitting yesterday and and noticed between the 3 final gear shafts a 1 thousands difference. We made them with a arbor shaft size shaft with 1/2 thousands larger then the mean of the 3.

The original looks as though it was cast with the back side turned. I like how the used that room in the spur for the drivers!! It was tough to just put a rim key on there, while still leaving the room to allow the rim to float to center!!!
But got that all worked out, while making it 3 thousands thicker at the weak point! I hope I can get a testing in over the next 4 days to get any other major kinks out. Not going to push it though. Because I have 50 blanks made, and don't want to have rush this. It will be a nice set up! Especially having that rim set-up will give me a lot of options with my 090G's

that is very nice! Good work.

Your gonna have to mass produce those so people can run 3/8" 16T

-The first tanks was with a .404 .063 on a 60" gb bar.
-now I drilled out a 44" gb bar for a 066, put that on the 090G. 3/8 .,050 chain! with a 8t rim.
-After that I am going to put a Stihl roll-matic 36" bar .404 .63 chain.

Then see how all points look at each rim and on the sprocket!
It's cool to have versatility!!!!

When you are ready to start sellin them sign me up for one.

COOL!!!!!! I need to hear that a couple times more!!!
I would like to sell about half of them at least!!!!!!
Let me run at least 20 tanks of fuel through them(and I cut through a couple 4 tanks today! Arms are shot!!!!!! LOL
So I can have some type of assurance before they go out!
So far so good. I have used .404 8t and 3/8 8t so far!

Thanks HOSS
More pics later tonight!

I am also very interested.

Bill

AWESOME!

If all goes well it will make it's debut at the Ohio GTG!!!!

Nice work teddy, it'll be interesting to see how they go.

I have a real nice spur gear on my 090G that was made by another member here, but it sure would be nice to have the option of a rim drive too.

I also have a couple of the spur gears!
By PA Plumber and they are pristine!
I got the latest batch and they are PERFECT! The hardness is is amazing as well, any one who knows machining knows that can be difficult , but he has it DOWN PAT! Awesome machining!!!!!!
For any one who doesn't need a rim sprocket set up, This is who you want to see! I recently got another 090G and he also had also bought 3 from PA PLUMBER. All in all I have 6 of his .404 spur gears! so I am well stocked on those!
I was just already knee deep in this project to back out, plus I want to run 3/8 5/8 chain to mill those NICE logs I get in.(gives me a extra board on logs larger the 3' in diameter especially when get a figured cherry, walnut, sugar maple but in, not to mention the priceless oak and walnut crotches!!)

Here's a pick of his work!!!! PERFECTION!!!!!

I know what some of you are thinking!
BUT THEY ARE WELL GUARDED!!!!!!

it takes alot of expertise to get something like this done(you had good coworkers)... looks as if was done right... good job...
