POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

[mattthemuppet2]

thanks! It did the job and my friend was happy. It had a fair bit of chatter with a CCMT insert, but that mostly disappeared with a CCGT insert, though each tip only lasted about 1 drum. Good chance I'll never use this again, but if I do it'll be handy to have!

I did a 1G on 1” plate: 6010 root, 6010 hot pass (I had planned on 7108 for the hot pass, but the root weld failed to penetrate all the way), 7018 the rest of the way out.

I had to switch from the fixture stand to the welding table halfway through because the plate was warping on the fixture stand.

I am also including embarrassing photos of the 7018 cap on pipe from yesterday, as well as the satisfactory backside of the root weld in that pipe.

Today i had one cylinder head to refurbish. I clean the parts as i went and got lot of work done, staff like lapping and grinding the valves. Then i found out some one has broken then drilled one of the exhaust studs. It was a mess, but i used some good drill bits to drill the centre and an allen key to unscrew what was left. Then i run a tap to clean the threads and used some 2K epoxy to give it a chance to hold. I still need to refurbish the rocker arms and assemble everything but i run out of time for today.

Today i had some time to spare so i decided to do a bit of cleaning. Today it's time to clean the inspection pit, first all the wooden covers come off and got pressure wash...

Spent a bit of time fixing things in the pit in my Dad's garage over the years. They don't like those around here anymore in new construction so my garage didn't get one.

They are handy for some things, but it always seems like the walls are in the way for doing anything that isn't dead center of the vehicle. And around here it always seems like you're crawling into spiderwebs in the darned thing...

I am working on a long, wide flat plate that clamps in a weld test stand that serves to prevent distortion of test sheets and plates. The welder clamps the coupon on this flat plate.

Machined bevels & landings:


Setup to weld the root:


Ground down 6010 root:


Back side of root (which I had to weld because I failed to get full pen):


7018 hot pass:


CLEARLY I am having issues with everything about my weld beads. I invite any suggestions for improvement. This doesn’t need to be a horror show.

Here is the flat plate finished. The square part of the plate started out as a 1” weld test plate, but it warped badly when I welded it. If you look closely, you can see the underfill in the weld seam right down the middle.

I thought it was funny that the plate that got warped ended up being a flat backing for other plates so that this never happens again.

I included a picture of the fly cutter in action at 600 RPM, .0022” DOC and a feed of about 7 IPM.

Today i continue working on refurbishing this cylinder head, all small parts got cleaned. And i assemble it and set the valve lash, and this part is ready to be put in to service. Its suprasing how much time it takes to clean all the small parts and assemble everything.

CLEARLY I am having issues with everything about my weld beads. I invite any suggestions for improvement. This doesn’t need to be a horror show.

So, let me start by stating that I've never stick welded. So this is sort of like the blind leading the blind.
But in general, based on TIG and MIG a few things to try that might help.

Before you run a bead, practice a dry run. Make sure you are comfortable going over the whole pass. If not, move so you are.
Practice a dry run or two trying to maintain travel speed. If you speed up and slow down the weld can vary.
With MIG there are patterns make to make the bead wider and uniform. Cursive 'e', or 'u' shapes. I think you do the same with stick, sort of 'stitch' back and forth as you progress.
Watch the edges of the puddle, and keep those within some boundary. Some straight line reference, imaginary or real. Something to focus on, and just touch the puddle against that as you go.

Maybe this helps... ...maybe not....

Well today i got to cleaning the corner of my workshop, it's always worrying when we have a clean spot in the shop. There is a machine that i've recently come to need because the prices have shot up. By tonight i plan to paint the corner and wash the tiles.

Yep, clean floor space can become expensive
