Thread: Bueller's shed - a noobs journey through vintage machinery

PDF sent,

Just watch out for that molten metal, we had someone get a spatter on the neck a few weeks ago in class..

It was nasty.

Got it! I'll watch out for that, the collar of my jacket comes up pretty high but I'll still be careful.

Had a bit of a practice today before running out of Argon (dammit), wasn't nearly as hard as I'd expected. Didn't get anything too pretty but got a nice functioning butt weld and a fillet weld which I got half done before the argon ran out. Both held up to the vice grip test, put all my weight into trying to break the welds and they wouldn't budge. Fun!

Edit: One thing I definitely need to take care of soon is my helmet. It does the job considering it was $175 down to $28 but I can tell it's going to tick me off in the long term. Really bad visibility once the shade kicks in.

You would get more and better feedback posting these to the MW Welding forum.

Try cleaning/flap sanding the joint, and see what affect it makes.
Read up about bevelling the join to get better penetration


The pics below show sometimes called "Scorpion tail" or "rooster", where the slag just comes off by itself
It means a welding "sweet/nirvana" spot has been hit.

Cheers mate, will do. I'm going to spend the next couple of days digesting that PDF bryn23 sent me and once I've got the Argon refilled I'll do some more practice. Have a feeling I was using too much power so I'll need to get that under control before I move onto the thin material I'm using for the chute.

You make a good point on bevelling the joint, I'd actually seen this in a ton of videos but it slipped my mind when I was cleaning up the cuts on the belt sander. Will give that a go next time.

Bueller is trying his hand at MIG welding: No slag. Your scorpion tail/rooster happens with a stick welder.

Was up at the crack of dawn this morning catching up on chores so I could focus on the jointer cabinet today. Couple of hours of sweating and here I am! Cut a new hole in the side and ground down the last bits of the bottom of the chute.







So I'm happy with where I'm at now, I can start taking measurements for the final cardboard chute mock-up. I've already made one so I know what direction I'm headed in, just needs refining a bit. Then it's on to sheet metal fabrication! Never done that before so another learning experience ahead.

Little preview on how the grille will look, will tidy up the opening a bit with a grinder and then tack weld the grille in place.

Not sure I would tack the guard to the stand.
I'd be looking to tack it to a steel frame that is bolted to the stand - then it could be removed a bit more easily if needed.
Can't think of why it might need to removed on a regular basis or even a long term basis, it's just the way I would do it

That's not a bad idea, it's actually the last thing that will get welded in place so I might weld it to a shroud and then bolt it on.

Great work, I've only jumped on this thread last night....

I've noticed that in at least 2 of your photos you have your angle grinder plugged into a partially uncoilied lead - the rest of the lead is still coilied by at least 7 turns on the holder.
I would encourage you to fully uncoil your lead when using power tools to avoid any voltage drops caused by the choke effect of coiliing your leads, plus you're reducing the heat disappation of the lead as well.
People can go years without issues, but the instructions for your tools tell you to fully uncoil for a reason.

Keep up the good work,
Des (near Pinjarra)

Looking at the vent I'd picked out and I don't like how much space it takes up, going to go back to Bunnings tonight and take another look around. Need to be careful of how much extra space I'm using inside the cabinet, still need to fit the motor and VFD.

Des,

I always knew there were issues with coiled leads. Heat and the resulting effects is all I knew. Thanks for the info on voltage drop.

Bob if Bueller were to slit some tube or pipe and slide it over the edges of the intake opening and weld them in place, would it smooth the air flowing into the cabinet enough to warrant the extra work? Kind of bell mouthing the opening.
