Acme rod?

[grahamshere]

Anybody know were one can get acme rod in Canada, im looking for 1/2 10 tpi or 8 tpi 2 start. I got a quote for 2 8' pieces for like $500 bucks, I don't need gold plated acme just regular acme, I know mcmasters has it but im Canadian so thats the end of that! Sorry that came out like that but hey, I phoned I dont know how many fastner shops and they dont even know what 2 start is, Any way if any knows please let me know. I think if any body has a cnc lathe I bet they could make a killing here in Canada. Graham

Try BCbearings.com in your area, or CBS equipment in eastern Canada.

You could just buy the plastic nuts that Roton sells and modify them like this.

That's what I plan on doing on a new machine I'm currently designing that'll use 3/4" 4-start screws.

Or send a small piece to DumpsterCNC and see if his nuts will fit, or if he can make you some that will. Probably cheaper than buying that tap.

I've ordered from Roton and was very happy with the product.Had it shipped next day UPS to Ontario.

The problem I've found with most Canadian suppliers for these cnc bits, is the people on the order/quote desk are overpaid, ignorant muppets! They don't even have a clue about their own line cards. After I spoon feed them all of the information, it takes them 3 days to get me a quote, and it's usually at a retarded price!

HI guys thanks for the help,

Ger 21, Im guessing the 1/8 file is for the groove for the o ring on the antibacklash nut. The flang nuts on the roton web site are 1.5" long and only .75 deep after the thread that would leave 1/8" thick wall, is that enough to make that groove with out it breaking?
Also notice they dont have any hex nuts for the hi-lead screws, Guess the would be easy to make with a piece of the treaded rod, there just for holding the rod in place.What do you think?

Cam1 , thats good to here because thats were im ordering from, I emaild them on a saterday and they replied to me that night so I was very suprised to see that.


Dsl, I here what your saying, I phone 4 places here in BC and not one knew what I was talking about.took them 2 days toget a quote, But $500.00 thats with out the nuts and shipping, dam at rotons you can get a whole ball screw set up for that. What are these people thinking? Think I need to get me a screw machine and start a new buisness lol. Graham

Actually, I was going to turn the groove for the O-ring using my wood lathe. The file was to round the end of the slots to remove the sharp corners which might be weak spots. You don't need a very deep groove to hold the O-ring.

Also notice they dont have any hex nuts for the hi-lead screws, Guess the would be easy to make with a piece of the treaded rod, there just for holding the rod in place.What do you think?

The reason you don't see any nuts for multiple start screws is because they won't get tight. If you need a way to hold them in place, you'll either need to get the ends turned down to mount them in a bearing block, or use some type of clamp on collars.

It can be hit and miss, after many years of procuring PT components, you get to learn which company and specifically which salesman in that company knows where to find stuff and get pricing quickly.
I have some really good guys locally who can source my items.
For leadscrews I generally look at either Roton or Nook and get them from local distrubuters.

[rancherbill]

I know it's a little late, but here's a source. Maybe for next time. They have a bunch of Canadian locations. Fastenal on the forums seems to be either a LOVE or HATE kind of place.

1/2-10 x 12' Plain Acme Threaded Rod
http://www.fastenal.com/web/products...ex?sku=0162475
$36.84 ?local stock? they say normally 3-10 days

1/2"-10 x 6' ACME Low Carbon Steel Threaded Rod
http://www.fastenal.com/web/products...l.ex?sku=47549
$22.26 should be a local stock item



or try Bolt Supple House

Hi,

I'm not sure about what is the acme rod vs normal one but you can find cheap ROD 1/2 or 1/4 or 5/8 at Home Depot or Canadian Tire.

They are much cheaper compared to the one find online

The price by 3 foots is 5/9$.

Rancher
Fastenal ONLY sells fastener grade ACME. This thread is about leadscrew grade.

Labidus
CTC/Home depot does not sell ACME rod (that I know of).
ACME and V-thread do not get used for the same applications.
Fastenal is generally 1/2 price to CTC (for OEM guys anyway).
