Got a chance to test out an ATV mounted SnowBlower (that I call "The Beast") that I built 3 years ago. This was my first attempt at welding something together and I half expected it to shake itself apart, but it worked like a champ (for the most part). It has some steering issues, but maybe someone will have some suggestions on how to improve on that aspect? Here it is in action:


And here's the glammer shot from from when I completed it (almost 3 yrs ago):


Didn't get to use it in the last three years, because it was doing it's job and keeping all the big snows from dumping on us - up until today...

Bring it over here! :rofl:

This drifted in 3 hours.

It seems that you might have 2 potential steering problem contributors. Steering issues are stemming from the 2 glides ( height adjusters) on either side of the chute and the caster carriage. How does it trail along when the chute is lifted up off the ground and it's just rolling along on the casters? Maybe the solution is to replace all the casters with some sort of PTFE polyethylene ski glides. Shoot... maybe you could find some sacrificial snow skis for this project. I had another idea of using 1 bowling ball dead center of that carriage that can freely roll around inside of a hemisphere instead of the casters.

I made an aluminum bushing for my bench grinder... got a couple of new wheels recently, a green silicon carbide wheel and a white alum-oxide wheel. Tried to fit the aluminum oxide wheel, and the plastic bushings it came with made it really sloppy. My grinder is only a 1/2" spindle, and the wheels were made with a 1" hole.

Anyway, since the bushings allowed for way, way too much slop, I made a new'un! Turned a piece of 1"+ alum on my baby Atlas 618 to 1.000", and then cleaned up and bored a 1/2" hole... actually ended up being .503, whoops! Hehe.

It helped out a lot, although it still wasn't perfect, strangely enough. I had to tap the sides and face of the wheel to get it to run decently true... but, had to do the same even with the wheels that came with it, so... I guess it's normal? Eh, whatever, it works now! I think I'll make another one tomorrow.

Spent the afternoon making a 1 1/2" dimple die set:

Finished up a connecting rod bolt for a 41-46 Chevy engine. Came out alright for what I need it for.

I finnished putting the deviding head I bought last eeek nack together. It was as nasty as the tailstock, but I tore it down and cleaned, degreased, and polished the rust off of it. The tailstock is next, then I have several projects to compleate with the pair.

This 6" three jaw came attacched to the dividing head. On a side note (tool gloat) I picked the trio up for $350.

I made a T-handle for my air over oil Hydraulic jack on my HF 20 ton press. I was getting tired of reaching for that stupid cumbersome pipe to open the release valve. Made from scrap bin pieces. It fits over the valve screw and uses the original press fit pin to hold it in place. I drilled a piece of 3/4" stock and faced it in the lathe. Moved it over to the mill to drill the 2 holes. I backed out the pin in the valve screw. Inserted the new handle over the screw and repressed the pin thru the new handle and valve screw. It works great. Now I can press and back off quickly. For operations like broaching, you need to press and release in steps, this makes it easy.
