What Did You Do Today (2017)

[Mark RandParticipant @markrand96270]

Tried out a new box of 2.5mm Murex Ferex 7018LT electrodes in practice for welding feet on to some 100mm square columns for a crane in the shed. They were spitting and crackling and making an attrocious bead, almost like wet 6010 rods. Dried them in the oven and tried again. Slightly better but still wrong. Used nearly 20 rods trying to work out what I was doing wrong. Then went on to the Murex web site to look at the specs for these particular rods. It actually says DC-ve preferred for these rods, which is odd. I thought I'd try that as my only other option was to chuck the lot and get some more.

 

Turns out that when I'd made sure to change over to reverse polarity, I was already on reverse polarity, So I'd been using the rods on DC Electrode Negative (like they allegedly prefer). Swapped to DCEP and they started to work as I expected. Slapped myself severely upside the head and gave myself a good talking to!

 

Then cleaned up and spent a couple of hours cutting up timber to make shuttering for a greenhouse base. That did go ok, even if I had to use the wood-spoiling bandsaw, instead of the proper bandsaw with coolant.

Thanks Joseph for all of your V10P info. At some point in the future I'll need to see to the spindle bearings in mine. Currently it is in a remote part of my parent's garage so not quite top of mind but in a long to do list.

Cheers,

Andrew Hutchinson

[Joseph Noci 1Participant @josephnoci1]

No Problem Andrew. I know the V10P well, so if you wish to ask about it I would be glad to help.

BUT, the deep dark depths of a garage filled with 'stuff' is a very sad place for a V10 to be…

I have often seen mention of vinegar as a rust remover as it is a mild acid. I came to the end of a large jar of pickled onions yesterday so tried some of it to soak some gears overnight. Seems to work, zero cost, uses up waste, kitchen friendly (put pongs). Just a report on activity please don't clutter this thread with more de-rusting advice.

These helmets might well be fine, but you only get one pair of eyes to experiment with. There have been horror stories about other cheap items in the past so I would hesitate to use a cheap item which could have possible bad outcomes.

Which is precisely why I wanted to show that not every one is useless, and that some work. The helmet is identical in every way I can identify to the helmet one of our professional welders at work uses for 8.75 hrs per day. I did not blithely use it for welding without a test. First off, held it up close to a bright light, then the sun (where I could see it switch on without needing to look through it) and finally using it for welding with my eyes initially closed and slowly opened them. Seem to have got a very good buy. Furthermore, no feeling of sunburn on my face & I'm very sensitive to UV having a constitution that suits me more to Lapland than Kent.

Regards

Richard.

Richard, may I ask, where did you get your welding helmet from and did it have a model name or other identifier?

I am sorry, but I am not sure where you detailed the item on here!

Still progressing on my V10 refurb…Slow, painful ( all my muscles ache!) and messy!>>

By end of the today though I am done, all parts are sanded, washed down with thinners, all masking is done, and all aluminum parts are cleaned and Phosphoric acid treated , ready for Priming tomorrow and painting the day after. The 'end' is in sight!>>

Here is a view of the Phosphoric Acid Treatment Workshop…

And THIS is what you look like if you don't get a life!

Even my Shoes have the same colour as my machines…

When this job is done all I am wearing there will go in the bin!

The welding helmets have a powerful UV filter built in, the auto-darkening feature is for visible light, so if it fails you will get dazzled, but not blinded.

So where do they come from Richard?

My 5" Brittania past it's hydraulic and steam test. I managed to get a couple of laps on the track too. Still got minor issues to sort out, one lubricaters not working and the regulator very stiff. The front bogie de railed a couple of times, on investigating the problem I found I had tightened the pivot nut too much so the bogies could not follow the track correctly. Well happy with the first outing. I should get the issues sorted out for Saturday 😁

That looks like car to suit back seat drivers, I'd better get one.

Fascinating, that would confuse the speed safety camera camera vans.

Following the recent discussion about impact driver type power drawbars, I've finished reconfiguring and installing the controller box to my machine, connected up the interlocks and tested it out. The electric impact driver will only engage and operate if the VFD "zero speed" output is active and the quill is at top of travel (where the driver can engage with the spline). I don't have any compressed air yet, so the engagement solenoid does not do anything but everything else is up and running.

Operation is simple – fast jog into the (upper) soft limit and press the up arrow button (tool in) or down arrow button (tool out). After a short delay to allow the solenoid to engage the splined drive, the driver comes on. Nice.

Milled the fins on the experimental heatsink I am making. That is 54 slots 1mm wide, 3mm deep and 73mm long, in a recess so a slitting saw isn't practical. All done with a 1mm carbide cutter on the CNC mill. On the first attempt the cutter lasted about 3 seconds. Sulked, had lunch and thought about it. I reduced the feedrate to 350mm/min, reduced the DOC and most importantly referenced the mill off the recessed face I was machining rather than an external face. With a DOC of 0.2mm you don't need to be far out for catastrophe on the first pass. Second time around everything worked; just as well as I only had two 1mm cutters.

To kill time while the CNC mill was running I made a couple of brass pipe connectors. Note to self: must buy some more slow helix drills to avoid 'hiccups' when drilling brass. In contrast screwcutting the 3/4" UNF threads took less than ten minutes and was pain free. I also tapped the 3/4" UNF holes in the heatsink, once the CNC mill had finished. A bit of manual milling and a good clean up to get rid of fine swarf tomorrow and the job is done. Followed by a good clean up of the machine tools and floor.

Also made a rhubarb crumble – the rhubarb travelled all of 15 yards from the top of the garden to get involved. I only made the crumble a few hours ago and I've already pigged three quarters of it.

the difference between involved and committed: just think of bacon and eggs for breakfast: the hen is involved, the pig is committed….

i do enjoy rhubarb in most forms…

Being a bit housebound at the moment did a bit more in the workshop.
Machined the big end holes I would have preferred the vertical mill but its accuracy is doubtful.
I have provision to be able to increase stroke if need be.
A lot of metal to remove on the cranks yet, screw cutting etc for bearing locknuts, sprockets and cam gears.
Dummy big end pin tried in mock-up con rod and needle rollers out of a jet ski.
Physiotherapy today at hospital but doubtful on benefits as already doing exercises to try to help walking with little success.

More inspired by the French Forestry Fire 2CV I'd have thought (being such a high class vehicle 'n' all ):

These vehicles were designed for narrow tracks where it was impossible to turn around and had a 'forward' driving position at each end. The steering at the trailing end was locked in the centre and the engine put into neutral. Then the new 'forward' end was used normally with the engine at that end providing the front wheel drive. Think they date from the early 1960's and around 600 were made. Due to the 2CV's problems with rust, they are now very rare birds.

Regards,

Richard

The rhubarb in question:

It also annoys my neighbour, because he keeps planting rhubarb and it promptly keels over and dies.
