Thread: Your latest project

whipped up a welding table out of parts i had lying around today
the top is off an old newspaper proofing press and its got about 4 thou from high to low as best i can measure should be good enough for my welding
stand came with a grinder I brought and the wheels are off a hospital bed i got for free
if i get exited i may give it a clean and lick of paint

that table looks kuta. how thick is the top.
the rest of the shed is looking good to.
well done

Hi azzrock

the top is cast and its made the same as a making out table with the webbing underneath
the best part is the sides are square to the top and to each other
being cast weld splatter wont stick to it either

A proud Dad is sharing a photo of a model solar powered car my son (12yrs) designed and built.
It was raced over the weekend at the Victorian Model Solar Vehicle Challenge at Scienceworks.
No place in the elimination event but the car ran when asked, stayed on the track, was mid field in the elimination and looked good.

His is the Balsawood monocoup body on 3 wheels.

The cars race on a figure of 8 track.

Cars are solar powered - no storage allowed (10 watts maximum panel capacity) -
Son and I had a go at making the panel - ended up with 7.3Watts.
(Cells from China, cut on a miniature table saw I made with a dremel diamond blade, potted in polyester resin, fibre glass matt as reinforcement, Balsa "formwork" ... the Balsa will need to change next time as too much differential thermal expansion)

Metal work, under supervision involved using the lathe and mill/drill to build

• Front axle (1/4" rod turned to 6mm for bearings and drilled to support guide roller posts),
• Front wheels (turned from an 80mm diam bar of Aluminium --- I did most of these and I will take guidance on parting as I resorted to the saw after about 15mm depth ),
• Guide roller mounts,
• Rear axle and guide supports.
• Not up to cutting gears so R&I Instruments were our friend for selected parts

The rear guide ... when front wheels were still plastic

The event is open to any school age person. Heaps of guidance from the Victorian or Tasmanian event web sites. Ian Gardner's guide is a must read.

Nice welding table, now I see why you were interested in those jig tables down in Gisborne.

Regards
Ray

harty. it did remind me of a marking out/jig table.
its really first rate.
you should keep an eye on that there is a few people around here that
would probably start scrapping it flat
the no spatter bit sounds handy. how would you clamp work
pieces to it if needed.
enjoy

Even tho the nice welding table got most of the attention LOL, I really like your sons work. Great to see someone having a go at designing and making stuff at his age. I like the welding table too but as I don't have a big chunk of cast.....

Middle of the pack for HUMPTY 02. I hope you got close to the faster cars and got an idea of what improvements could be made for the future!

Nice work on the solar racer give the young bloke a from me

it may get a series of tapped holes later but i need to work out the pattern to fit in with the webbing on the under side or make some bridge clamps that go from one side to the other

cheers

Bet you didn't get one for your old man! You know he needs one.

I have 2 of the cast plates he might get a surprise if he's good

Agree the table is a work of art. I did smile at the suggestion it would be scraped flat. Seems a shame to weld on it but much easier on the back than the trestle outside that serves some of the purpose here.

Have passed on your RayG, Dean, Harty and all the people expressing likes. Son this end. Thank you all.

Humpty 02 was my son's first go at a "design your own" car so reliability was a great success. Weight reduction, refinement in guide wheels mounting, increased panel power, greater rigidity of drive and decreased friction are all areas for attention in next years car.

Humpty 01 was a kit car in 2012, built on the kitchen table with no Dad supervision.... really clear instructions from the kit designer, it was a great way to start.... and historically carried an egg.... hence the name, But not as exciting to race

My son's mate built his own kit car this year and my son grabbed the interested younger sister of another friend to catch the Humpty 02.
The smiles on the young people's faces when the cars run is a treasure.

Have a great day everyone.

Following mention of this project in the little accident thread https://www.woodworkforums.com/f65/fi...ml#post1707914, I finally made a start on these today.
Materials used are: some parallel flange 75mm channel, some sched 80 (5mm wall thickness) 40mmNB pipe, some 18mm dia steel bar - I happened to have a suitable McPherson strut bar in the useful box - and some suitable ball races. I had collected 16 x 6203 bearing for this project already (40OD x 17ID x 12mm wide).
First cut and face pieces of pipe to fit into the channel (allowing for a thin washer each outside face of the bearings) and bore the ends of the pipe to suit the OD and width of the bearings. Next I cut (75mm long) and turned the ends of the bearing axles to suit the ID of the bearings and to match the bearing locations of the tubes.
I then cut a piece of the channel to see how it all fitted and discovered that the rollers needed a generous chamfering or rounding of the ends to fit deep enough into the channel. That was taken care of and some photos taken.
Next I'll drill the channels to suit and cut each one into a slot to allow assembly. I intend to just tack weld each axle end to allow future disassembly or repair. Photos of that and the finish to come soon.

A little progress today. I also had a play with the new SketchUp 2013 last night. Works quite well and I like the way you can generate standard dimensioned drawings easily.

IMAG0849-1.jpg IMAG0853-1.jpg

just a little drilling and tapping and three more to go....

That looks like it should work a treat Joe. Just make sure the floor is dead clean before you use them!

I'm not sure what the general wisdom on skates is, but one of the guys at the UNI suggested to me to only use 3, the old saying "a three legged chair doesn't rock" was used. In other words if you use 4 and the floor is uneven weight can come off a skate and it can be left behind with dire consequences....as i found out! Balancing 2.7t on 3 skates (and trying to get the 4th one back in) was not fun.
