WIP- Squatters chair-cum-wheelbarrow
Hello,
I have been looking at building a wooden wheelbarrow, one reason being to make some small wagon wheels for myself, as I've been learning the basics at work. There are some beautiful examples on the Net (one pictured below), but the reality is a wooden barrow isn't all that practical! I have an old squatters chair at home, and suddenly it hit me that perhaps I could combine the two. The idea of a wheelbarrow chair isn't original, see the Phillip Starke version here.
My squatters chair is the type with the fixed footrests, and they are an extension of the arm rest; the one pictured below has the footrests below the arm rests. This is probably the direction I will head- see sketch. This project is for an exhibition, so nothing like a deadline to get the juices flowing!
Onto the job...Andy Mac

Wip
I have a stash of silky oak, recycled skirting boards which I saved from a skip during renovations at uni. The profile is pretty odd, like a square S shape, but I cut the sides off on the bandsaw, and have now dressed it all. Some nail holes to contend with, and the finished dimensions are 67 x 31mm. I have some other silky oak as well, some wider and thinner, for armrests, and some much bigger pieces for the wheel rim. I am prepared to make two wheels if the stability is dicey, which will only come from a test sitting. The other unknown at present is the actual construction of the wheel/s, if I go for separate rim segments (felloes) or steam bent rims in two halves. Apparently silky steams OK, but I haven't tried it.
Here I have roughly layed out some of the components to get an idea of angles. I'm not working from a plan, just comparing dimensions between my squatters chair and builders barrow!
Cheers, thanks for lookingAndy Mac

Yep, I've found a nice comfy spot to sit back and watch this one develop as well.
out of curiosity, what's the deadline?Dragonfly

And the real purpose for the Wheel Barrow Chair?
So Andy can take it to the nearest watering hole have what is considered more than enough and then rely on some body to "wheel him home" after he falls asleep in the chair. The ride home will be a gentle floating sensation to which will aid slumber.
I like the idea
Back to reality....Andy I think that stability won't be a problem. It will essentially have a "tricycle under carriage" and the spread of the legs should give good stabilityJust do it!
Kind regards Rod

Hi Andy,
I love the idea of combining the two. I also will watching with the others.
Regards Rod.

Thanks for the interest folks, I'll try to keep regular updates.
Relatively comfortable deadline, the piece has to be at the gallery by 26August. Building a new steam bending setup, including an adjustable backing strap could eat into that! It is something I've thought about for a while, as bending timber is fun and adds a whole new dimension.... so this could be the spur.
Just on the topic of bent wheel rims, most of the examples at work are on lighter vehicles like sulkies and buggies, and the timber (probably hickory) is roughly 40mm thick. Last week I was doing a quick scout around all the vehicles for something else, when I discovered that one of the Cobb & Co coaches has wheels made from steam bent rims, and the hardwood timber would be about 90-100mm thick and almost as wide! A real eye opener! I'll take some photos tomorrow if I remember.
Cheers,Andy Mac

'Evening.
Further to the wheel construction, that is felloes vs steam bent rims, I took a few photos today.
The first is a wheel we are making, which uses the usual felloe segment method. The timber is mountain ash I think, which we buy machined from Sovereign Hill. The next one is a complete wheel using the bent rim method, a light weight wheel for a sulkie. I believe the timber is hickory. The one join I have marked has a mating one 180* apart, and are usually secured by a rim plate with two bolts. The next photo is the big wheels I mentioned last night, on a Concord style coach. The rear wheel (always larger than the front) is 1450mm in diameter, and the timber measures 50mm thick by 90mm wide... not quite what I mentioned yesterday, but still an impressive bend! As an aside, note the dark band underneath the coach, stretching front to rear. That is a thorough-brace, a suspension setup made from multiple layers of leather wrapped around two eyes, basically isolating the undercarriage from the coach.
Cheers, off to the shed to cut some jointsAndy Mac

Here's a bit of progress from tonight: marked out both leg sets and cut one angled bridle joint for a leg and its handle member, and then (bored with straight lines) I shaped the hand grip portion.
I have a couple of characters keeping an eye on proceedings, and when I stabbed my palm with the rasp and started bleeding on the timber, they sent me off, back to the house

Easter workshop time
Hello,
the frame is starting to take shape, and all is going reasonably smoothly. I continued with the three piece bridle joints, then tenoned the top ends of the front legs- as they are in two halves I cut double tenons to go through the arm rests. Then I layed out the back support and located it to with an almost half-lap at the bottom and a bridle joint where it meets with the rear of the arm rest.
I have been cutting the mortices by hand, and the tenons on a radial arm saw I scored some time back, but has been sitting on the floor till this morning. Great for angled laps and tenons!
After the two halves were dry fitted, I started with the cross members, simple m&t's, but I think that the front is too closed in... roughly the size of my squatters chair, but now I'm considering scrapping the two members I've cut so far, and tapering the frame? Front wider than the rear, and tapering towards the wheel.
Cheers,Andy Mac

Pity that you have to scrap the good work done so far!

I had a play with it this afternoon, adding angled cross members to give some taper. Angled tenons, hand cut! At least the mortices are square...
While I don't mind the bigger opening/entry to the chair (and squatters chairs are low, not easy to get in and out of, so the extra space is a bonus) I think I have gone too far. The handles of the wheel barrow part are now well wider than a normal one, which makes it a bit of a reach. The other thing to consider is the canvas sling, that will need to be tapered too!
CheersAndy Mac
