Some spacing issues have been correct. Hopefully, this is the final version.





I hope to cut this weekend...

Eric - how are you going to keep the gear lube off the belt?

Dave

There really isn't a way. Just going to lightly lube it motorcycle chain grease... just cause the stuff is sticky... Otherwise, the gears running the wheels aren't lubed either.

I would have thought that, for the amount of use it's going to get, the gears would last most of the rest of the life of the machine even without any lube? Or how about some graphite lube if that's available?

Anyway, this is top stuff, a real MadModder project - I'm loving it :) I may have to do something similar to a lawnmower, just for the hell of it!
Cheers!

Its fun using my brain for something else besides work. These motors, which I am sure you can get over there, can apparently be hopped up to 27+ HP. I am thinking a go-kart winter project might be in the works.

Well, I need a 5/16 endmill. Thought I had one, but I don't. Had to order it... Hope to have it by Monday or Tuesday. Project on hold for a few days.

Another set back. Had a minor emergency to take care off. Hope to be back on it this weekend.

Fun read.... Looks interesting.

Rather you than me.... However I'd much prefer this to re-lining a 12x8x3ft pond!


Good luck, Take your time... No rush  :thumbup:

Back on track. Sort of...

Last night I had a little bit of time and got into the shop. I did get all of the holes drilled out on the plate blanks. Unfortunately, I didn't get any pictures... well, they would be pretty boring to look at anyway...

I am hoping for time tonight to get the plates profiled and possibly get the bearing pockets bored out. We shall see. I promise to get pictures tonight. Profiling the plates will be slightly difficult as I believe I am just at the edge of my mill's Y axis limits (one of the reasons I am going to rebuild this mill).

Did some profiling tonight. Again, no pictures... Namely... it looks like garbage and I didn't feel like taking any. It has been a struggle all evening. The motor on this mill just isn't cut out for cutting anything but air. The motor constantly stalls and I end up blowing a fuse. So, I am out of fuses until I get over to the store to get some. I hope to get them tomorrow or Wednesday.

I am having to do the profiling in sections. My mill just doesn't have the movement on the Y axis to cut it in one shot (stupid X2!).

After the snowblower is done, I need to finish replacing the motor on the mill. I have built a new controller... I have a decent TM motor. I just need to machine up a new mount.

Frustrated.

I went to do some more work on it... Test fit the back plate and realized I put the hole .2" to close to the output shaft. Thought about just slotting the the mounting holes, but I don't quite have the room I need. Soooo back to the drawing board.

Ended up ordering new bearings for the mill motor. Hope this cures some of the issues i am having. Should be here tomorrow.

I had to replace the bearings in the mills motor. They were shot. The mill is much quieter now. I am still having issues with the controller (an old Dell laptop). It will freeze occasionally and I am losing some steps somewhere. I do have a replacement PC... I just have to get motivated to replace it.

I started to mill the plates. I know it looks like I made a mistake in this picture.With the travels on my mill and the lack of the Z being under CNC, I had to cut some clearance at the start. I did get it a little too close, but it wasn't an accidental crash.





I did have a crash though. I lost some steps somewhere and messed up both plates. I have to clean them up and figure out how to recover. I don't want to re do this.

Had a bit of motivation today. Woke up to this:



So I spent a bit of time in the shop. Corrected the machining mistakes the best I could. Turned up some spacers. Tapped, slotted and bored the plates. Did a quick test fit.



Then I drilled and tapped the gears for the grub screws. Cut the 1st groove in the new shaft for the C-clip. Mounted it up for another test fit.





The gears seem to mesh nicely. I need to trim the new shaft and cut the groove for the other C-clip.

Once that is done, I can reinstall the drive mechanism and fully mount the new engine. I still need to figure out how I am going to build the mount for the rod that spins the chute. I have one side figured out. Can't do the rest until I have the blow back together. Hopefully by Tuesday I will be working on that piece.

Snow is a good motivator. We got about 15 cm of it for two weeks and -16C (pretty cold - unseasonally). Now it has been raining and +6 for four days, snow is memory and because we have only few hours of daylight all looks pretty dark. I would take the snow.

Update...

I have almost all of the parts made. I need one more piece as bracing for the chute pivot mount. I ordered a bunch of hardware to assemble it. Should be here tomorrow. I also ordered new shear pins for the auger and ordered some rubber "paddles" for the impeller. <-- more on that later.

I also cleaned up the parts I made. I don't have any pictures today... Phone died ad it is getting late. I will try to get some up tomorrow!

I get it! Pictures inbound!

Collections of parts for the gear reduction and pivot mount for the chute.



Starting to mount things up



Ready to go. Almost...






Before anyone says it... Yes, I know, my shop is a total disaster. That is a winter project. Cleaning and organizing!

So, the back part is almost ready to go. I need to mount the handles and adjust the drive. Then it is on to the front (were it eats the snow). I want to clean it up, do a little work and mount some rubber paddles on the impeller.

So... more pictures later.

Nice work Eric, glad it's coming together, I feel a certain proprietorial interest in the concept  :thumbup:

Very nice work! Don't beat yourself up because you think your shop is a disaster, it doesn't stop you from doing things!!

All the best, Matthew.

***Update***

I decided to paint it yellow, add a headlight and stretch the auger to 24".
