[Firestopper]

Firestopper, why would you not grind aluminum?
I Surface grind aluminum regularly, not for heavy removal but for flatness. I use mist coolant and the same wheel, works fine, try it sometime. Just block your alum parts with some steel

I was taught many moons ago (HS) and reinforced in the Navy to never grind nonferrous material on a bench/pedestal grinder. I have seen first hand a heavily "packed" wheel from someone in the shop grinding aluminum.

I know nothing about surface grinding machines or wheels for nonferrous use (don't have one). Just making sure folks understand the dangers of grinding nonferrous material on commonly found bench grinders.


We got Marks (mksj) new mill delivered and set up. I was surprised to only find one drop deck trailer available for rent in Tucson and they are proud of it too. $150 out the door for a days use. They also hit the customer for $7 on anything that has tires (environmental fee). The deck condition was less than desirable, but we made it work.

We also took along a 4'x4'x 1/4" steel plate to reduce the angle of departure for unloading as we could not take the forklift for unloading. We used a come- along for more control during the unloading. Marks driveway is quite steep, narrow,curved and short so backing in was tricky.

Notice the 1" spacers on the casters, this was a big help in preventing a high center condition even with the steel plate to reduce the angle.


Edge protectors where used on all corners and painted surfaces as well as 2x4 cribbing.

The mill was located, removed the caster spacers and leveled.



The mill now sits as close to the ground as possible (1") at low end leveled.

Another fun project with excellent results.

Thanks for looking,
Paco

Use bees wax to load your wheel to keep from loading your wheel with alu.....

Not a machining project but this will get all the lawn equipment out of the shop.

A friend was selling a shed on Craigslist but because it was over 12 foot No one would touch it. He was thinking about tearing it down. I live four miles down the road , was in need and hate to hear " it can't be done".
I found a cheap torsion axle widened it to 14.5 feet and installed a tongue. It was heavier than I thought bending the axle and tongue so we cut holes in the floor and strapped them up.
The looks on people's faces when a 12x14x13 building moving is priceless.

You've been watching too many of those "mega-moving" shows on tv! Good job.

Well after watching that video I never want to use my bench grinder again!

I don't...just belt grinders...never liked grinder wheels much to begin with

Very cool. Glad the local Gestapo didn't find you on the way home. Cheers, Mike

What did I do in My Shop today...I messed up two, count 'em, two projects. x

First I had hobbed a drive on the shaft of my going to be dividing head, to match the worm gear. Forgot to check the thickness of the tube, hollow shaft doncha know. While reseating it for a test I tapped the end with a brass hammer and cracked that shaft right in two pieces. Dang! Musta gone too deep...ya think!

Then I went to my mill and figured to finish the other project which had been languishing there for several weeks. Well my set-up wasn't as secure as I thought and the piece spun and ruin my project. Dang! Check twice, cut once comes to mind.

Ah well, look at it this way, I now have two 'new' projects to work on.

Whyemier being optimistic. Having a beertrying to stay that way! I hate Murphy!

Some how my daughters boyfriend managed to loose the half moon bed assembly washers for her bed when they moved..



hope he measured right

I know how you feel, had that earlier in the week. Now I have started to the new project of building a new backing plate. A lot of turning to turn the 7" round into a backing plate.

I feel for you, been there, done that, unfortunately more than once, I'm a poor learner.
