Robot Arm

[Arbutus]

I've been making up a list at AliExpress since I need 32 different screw types. I think I will finish the spreadsheet of all the screws and get Spaenaur to quote but for this cheap (well not really cheap) robot arm I'm not sure I need an extra 87 screws if I have to buy a box of 100.

Even McMaster Carr can supply these of which I need 13 according to the parts list.

Where AliExpress wants 1/2 of that but of course I'll have to probably wait a month where McMaster Carr will ship on Friday.

I wonder if the quality is any different. Shipping is about $25 from McMaster Carr.

I've been purchasing metric screws (Black oxide; hex socket) from MMC for years and I have a substantial inventory. Their screws are significantly harder than the offshore cheapies. But the main reason I keep using MMC is that their products are consistent and I can rely on them for the same quality over many years of orders.

If you only need a few dozen screws John, just DM me.

Thanks. I know I want some just for general inventory. I already have a supply of some sizes. Just not everything for this Robot Arm. I've got an order coming from MMC but it's for mostly work-work stuff. I usually add some of my own inventory onto it to save shipping. Impressed with their delivery statement. Theoretically I'll have the stuff on Friday.

How about that. Ordered from McMaster Carr Yesterday and they arrived here just before 7PM. Now I have no excuse to finish building the power supplies for my client. I also received the 3 bearings, slotted shaft and key for the Robot Arm. Now it's just screws, machined castings and motors/gearboxes/encoders left to procure or build.

But tomorrow I have to mow the lawn... again...

Ordered yesterday and they are here overnight! From the US! I’ve ordered from them before and been similarly impressed. Expensive though.

It was impressive. Here's the tracking info. Shipping was $21.84. One has to wonder why, if it's on the vehicle at 9:08 AM that it takes until 6:32PM to reach my FRONT DOOR.

How many Tims are there in Victoria?

Hamilton, ON to Victoria, BC . . . in less then 24 hrs . . . for $21.84 .
I think that is fair.
. . . next time, ask him to pick-up a Medium Double-Double . . . also !!
