Still not got the tubes rolled by the boatyard but I did get the front sliding door made and welded in place.

Also was going to be welding some tabs onto the hex bolts of the 220mm stainless clamps so a spanner wasn't required as they will be removed at least once a day but then decided to put a wing nut on the opposite end and weld in place. That means they can still be used with a spanner if require, only thing is they can not be dismantled but that won't be a problem for this application.

A friend then came in asking if I had any bits of aluminium he could take home to fashion some sort of trolley out of. It is for his son who has a joinery business and often has to struggle up the side of houses with patio doors and double glazed units. I said instead of him messing around with grinders and hacksaws that I could just cut it on the plasma. He told me what he was thinking of so I drew it up in Fusion360 and once he was happy with the design it got cut on the plasma and welded up. Still have a clamping mechanism to make, I have an idea or two but he will have a word with his son to see what he thinks would be best.

Ok the quick model drawn in fusion, it consists of two bits of 3" x 3" x 1/4" angle, a flat plate to give the width and a couple of sides where twin wheels will be mounted on an axle.

A few minutes on the plasma and a bit longer welding and this is it so far.

You might find a pair of the cheap Chinese ...... eBay 150 or 175 mm dia non puncturable softish yellow rubber wheels are useful as they can go over a four inch kerb & gravel without too much effort when loaded up
You might also need to put a decent set of sealed for life bearings in them and studlock the nuts on the split rims bolts . I had to do that on mine as they often came undone & the supplied bearings were very playful & graunchy after a few months of use.

One thing off the todo list. I’d say these were borderline acceptable enough to keep but it’ll give me some milling practice machining the faces.

Dev , what casting medium are you using I'm asking as s being new to casting at home in aluminium & brass the finish on the castings looks quite good .

He has wheelie bin wheels, I suggested he would be better with pneumatic or puncture proof wheels but he wants to stick with them, probably because they are free

It’s reclaimed Ali. The scrap is melted down into ingots to get rid of any impurities before it’s used to cast anything. Don’t know if it helps or not but it works for me, YMMV

Check TYA's posts re smelting - he's well known for his artistic [well, someone buys them] results.

Sorry I didn't put it well enough perhaps , what were you using for the casting sand ?

 

[Dev]

Ah right. Bentomix.

Bentomix XTRA Oil Plus Oil Bonded Sand

Bentomix XTRA Oil Plus sand has a special mix of processing oils, Catalysts and bentone binder instead of the bentonite clay and water as used in traditional green sand. No steam is generated when the metal is poured. This means that there is a reduced need for venting of the mold and the sand doesn’t need to be as permeable. Therefore a finer mesh of sand is used which results in a finer finish on the cast part. This also means that the sand does not dry out by evaporation.

Bentomix XTRA Oil Plus has a higher green strength than Petrobond and is Commonly used in the foundry industry.
Ideal for more complex shapes and lettering also very good with finer detail

do you make the to sell ?

 

[DAPPH]

Ah right. Bentomix.

How reuseable is it or is it a one pot shot .

 

[Dev]

I’m faaaaar form an expert, just a novice following the path of St.Myfordboy

The bentomix is not one-shot, I don’t know exactly how long it lasts, I’m not using it every day or anything but I’m still using the stuff I bought more than 2 years ago.

I’ve also used sodium silicate and fine* sand cured with co2. It’s single use. It is cool though and useful for more complex shapes and cores.

I like the sound of your casting medium .
I too have been seeing what MFB was doing . Had a casting made with sieved moulding sand & finely liquidized ( cat litter style ) montmorillic clay aka bentonite ready for pouring . Made the mould up five days ago , this afternoon moved it to the mounting board off the work top where I'd tamped & locked everything together , lifted it up and the whole casting form fell out the drag . Who left it in a place where it got blazing sun for five days


Lesson learnt ............ it dries out quick, the moisture being absorbed by the wooden frames and gets very weak , even the two small battens glued & screwed to the each of the inner walls as keys couldn't hold it in place, it got that dry .

I hope to have a new mould making session tomorrow .

Not a recent one but was trawling some old images on the PC and this was something I made for the kids from some home milled Walnut and oak - must admit looking back I was quite pleased with this. Still going strong and I hope will become a family heirloom when I`m gone.

When the company that makes the skins gives to long a lead time ....adapt and overcome

Got my handrails back from galvanising and powdercoating so fitted them last night.

Got to go back later in the week to resin in one of the anchor bolts and swap a couple of bolts for correct length, but otherwise pretty happy with it... customer seems happy anyway

I've always had a 'thing' about rocking horses, maybe some throwback to the fair grounds of my youth, but we got one hand carved for my daughter when she was a baby, in the Philippines 18 years ago. It has been carted back and forth across the world several times, and resides in my hallway now.

Is that a Manx rocking horse?

I made an axe sharp,,, maybe too sharp, I tried it on paper and sliced it with a razor clean cut.

Used a file to get small chips out then worked up sandpaper then onto a homemade wooden strop wheel I mounted on the bench grinder and use buffing compound gets it up to a mirror shine in no time.

still got a big chip at the bottom to get out somehow if anyone has suggestions then feel free but the axe works fine with it I think.

That will be good to make dowels and pins to hold big timber together.

If you do, trim, adjust the handle just below the head to make a better grip.
