Jive/Salsa R2 mixture

[Burgerman]

Maybe, I never made a magnet. But I have a few motors. They look like this:

I have a large n50 one too and dropped it into the bench, floor which is concrete etc many times. Not a blemish. And it shoots out of my hand and hits anything iron pretty fast! Also the ones with a countersunk hole in I have screwed to the wall to hold my gate shut. Nithing shatters when tightened?

[Burgerman]

Ferrite type
Compressive strength (N/mm2) 800
Tensile strength (N/mm2) 35

Typical chinese N50
Compressive strength (N/mm2) 1100
Tensile strength (N/mm2) 75

According to wiki, so twice as strong. https://en.wikipedia.org/wiki/Neodymium_magnet

They use a weird bonding thing...

1. Classical powder metallurgy or sintered magnet process[11] old type.
2. Rapid solidification or bonded magnet process

[Burgerman]

Removed 30mm thick foam pad from the centre footplated and replaced wiuth a 300 x 240mm carbon fibre 3mm thick proper autoclaved sheet. Worth about £30 but I had it... Left over from some motorcycle project years ago.
Since it was sticking out and holding my legs from the footplate rear edge. Now it doesent!

Actually looks great. When you photograph it it does weird shit with the sensor. And looks brown/dull... Something to do with having no low pass filter on the D810.

BM, how do you strap your legs to the center footrest? Some pics will help me much

[Burgerman]

I dont. No need. I do use a "bum bag" as a strap around my legs to keep my knees together and to keep money, keys, cards, pills, sunglasses, torch etc in.

If you need some strap, you could bolt a velcro strap to the carbon plate. To loosely go around your legs. Its really strong. Its not pretty shiny ornamental carbon fibre as used by boy racers, but real autoclaved pre-preg engineering stuff as used in formula 1 race cars or aircraft parts. Its seriously stiff, even though just 3mm thick. Light, but you cant break or bend it in any way. If you put one end in a vice and hit it it rings like hard metal sheet. If you drop it it sounds like glass rod. And you can swing on it with almost no flex and you are not strong enough to break it with a hammer. Way too good for that footrest leg plate! But I was using it to mount brake calipers on a big motorcycle. Its a leftover... So it got used.

[snaker]

If moving on difficult terrain and uneven surfaces, I am afraid that the feet easily go off the footplate. I am actually using the swing away footrests and I have to strongly strap my ankles to them. I have not found a sensible way to strap my ankles/legs to a center footrest yet.

[Burgerman]

A single wide velcro strap around your legs near the bottom. I used to do that. One bolt on each half with a large washer and then good to go! https://www.amazon.com/VELCRO-1804-OW-P ... B00I0TTPL8

[Burgerman]

You cant have tilt or recline, esp both, without a headrest... Your head is heavy!
The stock headrest mount that sunriuse supply, requires that it is fitted over the huge push handles, sticks out about 9 inches total, and looks terrible.

So I threw it away as you do, along with all the adjustable knickles that nobody needs, and then made a stronger simpler much lighter mount that mounts where the seat recline actuator goes on the cross bar on the seat back.

Basically I added 2x bits of 5mm thick x 25mm angle iron x 75mm long. And 2x alloy bars, 13mm diameter. At the top added two M8 "eye" bolts. Easy, 10 mins work. And a few 13mm spacers at the headrest mount.

And push handles now shortened by 7.5 inches. I can now turn around in my van, at my PC, or in the toilet, without ripping chunks out of the wall or knocking the computer off the bench... And it wobbles less, looks better, and saves about 4lb...

Replaces this (not my chair, same setup...) here:

[CPguy]

That looks so ... disabled I guess! Right you are to improve on that!

I would not want to be found dead in something as ugly as that...

[Burgerman]

Its not just me. Or you. NOBODY wants it. So why do they do it?

Its like they are trying to make it as badly thought out as they can. To use up as much metal, with as many parts, bracketrs, & bolts as possible. That makes it over heavy, over complicated and as ugly as possible. So that nobody wants it. It also makes it 10 inches too big/wide. Hits everything around you. Maybe they want to sell as few chairs as possible?

Changing half a dozen such cockups on this chair (or any production chair) turns it from a thing of horror to a desirable, properly functional chair. That leaves one question. What are they thinking?

It remains the best rear wheel drive chair available at the moment however! Just requires some minor improvements. But all do.

Sorry back again...

After being turned down by WCS due to not requiring an indoor powerchair, I'm still after a used salsa r2. I know roughly what used chairs go for + shipping cost. So I'm trying to work out the overall cost £ to get one how I would like. I know roughly what a used lift+tilt+recline chair goes for used. I've asked rover220 for a price for a fixed centre footplate (if he has one), and also does it just bolt on?
I'm assuming it won't cost me anything to move the seat back apart from skinned knuckles and some cussing.
How about changing the 12.5" solid drive wheels and solid 9" castors tyres and perhaps wheels to give a more cushioning ride and nicer look?
I don't know this Shirley HK gentleman so will have to buy in UK. Also if I changed the drive wheels I'm guessing I'd need to get some of them spacer plates made like BM.
I don't mean to be ignorant but it is confusing for me. I just want to sort myself with a usable powerchair which will give me an additional mobility tool (along with my scooters and manual chair) to get me out and about to where I want to go.

Could possibly BM or someone else list what parts I would need and a ballpark figure for them? But not including the centre footplate as I've asked Rover220 for a price for one of them. I can then tot them up with the cost of the chair, shipping and possibly batteries to get an overall price to get myself powerchair mobile.

[Burgerman]

Its not that simple. It all depends what you buy to start with. A simple lift or no lift on an order form changes a lot of other parts and so alters what you may need. Same goes for every tick on the original order form. So before anyone can advise then you need to know what you are buying, and what you intend to do. Somewhere I already made a list of what you should buy initially in a chair. Have a read through my thread here from the start.

Sorry I know you have. I didn't like to mention too much about the chair I've got my eye on, as I was worried about someone else buying it . Basically the chair I have my eye on is a Salsa r2 with elevate+tilt+recline. Initially I didn't think I wanted a chair with elevate+tilt but have now decided I do (I can take or leave recline). Also the chair has 70 degree leg hangers.
You are right I should read back through this thread as you suggest. Sometimes the lazy option is type a new/repeat question

[Burgerman]

What motors?
What controller?
What power module?
Powered legs?
What arm type?

[Burgerman]

You will find most are 90A in place of 120A unless ordered otherwise.
Also can be r-net or Vr2.
Also most have horid wobbly lift up arms. And a loose weak too low, and too outboard swing away.
And most have 14 inch tyres/wheels unless ordered with 12.5 ones.
Most are 2 pole, and 4 mph. Some are 2 pole and 6 mph. You want 4 pole.
Most have unbelievable headrests!
All have the seating way too far forwards.
All have 7 inch long push handles. Often with an extra 7 inches to mount a headrest...
Most have the back configured too low. And the arms too.
All need the thing reprogramming.

[Scooterman]

What motors?

10kph 4-pole
R-net LED
VR2 90Ah
70 degree swing aways
12.5" solid drive wheels
9" solid castors
60Ah x 2
30cm lift + 30 degree tilt
EDIT: flip up armrests

[CPguy]

R-net LED and VR2 90A is not possible. Either both R-Net or both VR2. Check again!

[Burgerman]

Then you need only, 70/80Ah batteries, or lithium.
Seat moving back (which may or may not be easy depending on a few things).
Centre footplate (bolts straight on)
Swing away and pod positioning means
Programming
Headrest dealing with
Arms reconfiguring or better still aquire some single post ones.
Wheels if you wish, and tyres regardless.

Excellent! Thank you BM.
(Rover220 can sort me re the centre footplate)

[Scooterman]

R-net LED and VR2 90A is not possible. Either both R-Net or both VR2. Check again!

The seller emailed me the order form but I know nothing about powerchairs.

[Burgerman]

Well thats a contradiction.

An R-NET control pod requires an R-NET power module. And that can use this too, so start saving! http://www.cw-industrialgroup.com/Produ ... CJSM2.aspx

R-Net http://www.cw-industrialgroup.com/Produ ... R-net.aspx

A VR2 Controller needs a VR2 power module...

[Scooterman]

Here's a photo of the controller.
So do you think there's a mistake on the order form?

[Scooterman]

Perhaps I should a horse instead, probably be cheaper?

[Burgerman]

On the order form both VR2 and r-net are ticked... Which cant work.

Thats an Rnet LED joystick pod. http://www.cw-industrialgroup.com/Produ ... R-net.aspx

[Scooterman]

I'm confused?

These are the only options on the order form. All the other guff is about legrests, armrests, seat width, wheels, etc
If as BM says the item we can see is a R-net led joystick. Then that must mean the VR2 90Ah controller is wrong?

Does it matter? The chair obviously works, but I assume if it's got a lower power controller then the spec isn't as good?

[Burgerman]

Then that must mean the VR2 90Ah controller is wrong?

Yes, its got an r-net 90A one instead, since thats the only one that can be fitted. Or if really lucky a 120A one, but thats not a stock option.

[Scooterman]

Thanks

Re the centre footplate. I notice from looking at the parts manual the footplate is attached to a 90 degree hanger arm. This knee angle would be too tight for me, I need 75-80 degrees. Two options I could think of would be: a) Cut and re-weld hanger arm at 75- 80 degrees. a) cut and weld some form of lockable hinge or mechanism in place of elbow that can be tightened at desire angle by an allen bolt? I haven't a clue if something like that is available so probably the simple option would be a) cut weld re-weld in desired position.

What do you think?

[Burgerman]

As far as I know there are lots or types and all are about 75 degrees. And would need to be to clear wheels.

Oh I didn’t know that. The only one I’ve seen was on a salsa m2 (and your chair). I might ask rover220, he might know more having a few?
