Project Mini Hägglund

Finished:

Unfortunately it doesn`t work well with the 2 3/8" holesaw that i need, but works well with the 1 7/8"...

Exelent idea. Thanks.

Wish I was your neighbor!

Thanks guys...

Machined a new shaft today:

Everything together:

Works great:

Wow:Wow1:that is so cool Steinez! I wish I had a tubing cutter like that. But I guess I need a shop first.:ylsmoke:

You're like a German McGuyver! This is awesome

 

[Steinbruchsoldat]

Thanks guys... :smiley_drive:

The belt sander really needed a spark/dust guard, so i made one today. Started with a barrel:

Added some speed holes:

Drive wheel guard:

Removable grind wheel guard:

Everything together. Needs paint bad:

Also mounted my "new" grinder:

This thing is awesome. Has lot`s of power and never bogs down... :Wow1:

Stein,

It's sure fun watching you work out solutions to your tool needs. Here in the US, we're spoiled with easy access to cheap China-built tools, BUT you get what you pay for. After viewing your notcher, I looked up some of those cheap Harbor Trash notchers to compare them. Yours looks a lot less polished, but lots cheaper and way heavier built. I'll also venture a guess that yours will last a lot longer. I hope you won't be offended if I copy your design!

Anyway, thanks again for an entertaining thread.

Thanks. I`ve always been jealous when i was in the US and saw all that cheap stuff. But yes, you get what you pay for, but a few things are useable...

Finally started working on the Hägglund again today. I continued fixing the track assemblies, so the grousers won`t hit them anymore. First i removed both:

Then i made some parts:

And welded them on:

I know, it`s a bit ghetto fab, but it`ll work for testing...

I really love this!

You not only scratch build a unique vehicle, you scratch build the engineering tools to enable you to build it better!

Fantastic!

 

[Steinbruchsoldat]

Mounted the track assemblies and put everything were it`s supposed to:

Then i started with the frame. Leg room will be tight...

Stein,

Interesting changes.

From the #2 photo above, it appears you've mated the axles from the rear differential out to the drive sprockets. Earlier, you'd mentioned not being able to mate the drive sprockets to the front axles:

And, it`s everything else than easy to run the front axle outputs to the drive sprockets. I tried it and failed...

What was different about the front axles and the rear axles which made the current set-up (rear axles) work?


On a side note, I've noticed that most newer snow-cats have the drive sprockets in the rear, and it was explained to me that it was easier on the tracks going uphill. Do you have thoughts on this? Did you locate your drive sprockets in the front out of respect for the original Hagglund design, or for other reasons?

I could mate the front diff outputs to the drive sprockets with the shafts easily. Problem is the placement of the engine. I can`t put the engine in the front and i can`t put the drive sprockets in the rear. So the power needs to be transfered across the vehicle from the rear to the front.

There`s no difference for the tracks or driving abilities whether the drive sprockets are in front or in the rear. I placed them at front because it`s the only possible way. If i`d put them in the rear i`d be driving on them and that`s not good. It also wouldn`t work with the drive shafts to the sprockets...

Stein,

I've been loving your work since the first post. You're a real go-getter, for sure.

Any worries about the center of gravity? With the short wheelbase (trackbase??) and all, makes me wonder if you'll end up on the nose, or on your back. What's your senses telling you?

 

[Steinbruchsoldat]

The cog is actually pretty low, ist just looks very high. The weight distribution is also really good, there shouldn't de any problems. I also was able to lower the engine a bit with the new design...
