Hi all,

The supplier thread above seems to be locked, and the thread it links to doesn't exist, so.... Here's an attempt to create a new supplier thread.

I have found and plan to use the following suppliers to build a JGRO...

Suppliers
======

Small Parts and Bearings Most of the hard to find bits including but not limited to couplers, bearings, Delprin etc. Big catalogue although I haven't ordered from them (yet).

Jaycar Electronic components. Most of what you will need if you want to build your own breakout board and driver boards.

RS Components Electronic components and engineering supplies. If nowhere else these guys will probably have it, I will be sourcing the toroid for my power supply from here.

Oatley Electronics Surplus and electronic bits supplier. In particular they have the IRFZ44 FET required for the driver boards, get em while you can... Always worth a look at what these guys have. Their CNC drivers and constant current drives look the goods for a CNC.

Futurlec Some of the harder to find components, namely the motor controllers needed for the PICSteps and other bits and pieces. These guys also have a PCB fabrication service which doesn't seem all that pricey.

Ocean Controls Industrial and commercial electronics supplier. These guys have steppers at the best prices I have seen in Australia for new steppers, still very expensive compared to the US though.

Southern Steel Cash and Carry Steel supplies, in particular the black pipe required for the bearings.

Bunnings - MDF, Bolts, Screws etc.

I bought my steppers from an E-Bay supplier in penrith (it_equip_on) who repairs printers for a living. It may be worth mailing him directly or watching for his auctions.


Suppliers Wanted
===========

* Aluminium Plate - 12-20mm... Perhaps a scrap merchant.
* ACME Thread - 10TPI (I can find 6 TPI).

[Dethaspagan]

I am looking for an ACME Thread with 10TPI as well. So I am going to ask where did u get yours from? (I dont mean Agro)

[Celtichawk]

Try RS components for couplers, prices look good, not the US but still better than most. Ocean Controls for steppers?

[andy_ck87028]

Power supply components?

Andy

(edit: whoops in original entry, but what source is the cheapest?)

[Agro]

Added to the list. Cheers

Jason.

Andy,

Try RS. I will be buying the toroid, bridge rectifier and large cap from them. I'm a little surprised how hard it is to buy large transformers these days, a few years ago
you could buy them from dick smith.

Jaycar have toroids, Altronics have a wider range including some with low voltage tap for the logic etc. Been using a 160VA on the micromill hardly gets warm, Got a 300VA for next project.

[Agro]

I missed the toroids at Jaycar... I will drop in to their warehouse today

The 18v 300VA looks the goods. This should rectify out to 23v and supply a healthy 16 amps which I will be happy with.

Cheers

Agro.

We use those toroidals all the time. We have not had one fail to date.

I have found that a good place to go for Aluminium Plate is to find a local trailer body builder or bullbar manufacturer. They generally have good size offcuts up to 16mm thick. I used to use Heard Bullbars here in Wollongong but they went belly up a few weeks ago.

Anyone got a source for V bearings? I need 6 at max.

Andy

[Greolt]

Alltronics have 300va toroidals on sale for $40.00 usualy $80

Just got myself on with 30v 5a - 30v 5a - 15v .5a - 15v .5a

Should suit my need just right. About 42v rectified at 10amps.

Can run some regulators for 5v control and 12v fans on the minor windings.

And I ordered yetserday arvo and it arrived at 8:30 this morning.

Can't complain at that

Small Parts and Bearings have them listed but don't carry stock according to their site.

Exy About $40 and about $60 with stud.

Greolt

[andy_ck87028]

Thanks for that Greolt

I'm very interested in the toroid at that price.

Could you give me a web link or phone number?

(NB I was also at Nigel's bbq last week.)

[andy_ck87028]

Thanks Greolt

Excellent tip off. Have bought a 35V + 35V + 15V + 15V 300mVA toroid for $40. Picked it up from the store an hour ago.

For any other Aussies going down the Gecko path, consider this opportunity now.

These guys have a website... www.tea.net.au... TR20x4x2000 $154.65 but they will cut in increments... Finest pitch in rod above 10mm is 4mm which will give you roughly 6 tpi They do rods at 2 and 3 mm pitch but only in 10mm major.

You can also try the following site www.motiontech.com.au
the guy to speak to is Kevin

TR20x4x100 is approximatly $5.00..any length up to 9 meters ...

Cheers Mark
