A 750 (1hp) watt servo will only draw about 6.25 amps under full load. If you have a 20 amp circuit available great but your standard 120 volt 15 amp household circuit that isn't loaded up or has other motor loads will work quite nicely. I would check the circuit you planning on using and see what is on it. These days it is more unusual to see 120 v 20 amp circuits unless it is for a particular load reason.

Thanks kgg. My outlet is set up for a 20amp breaker. So I should be ok.

An S point needle looks like a chisel and makes a perfectly flat hole running parallel to the line of stitching.  It will look a lot like the LL but without a hint of diagonal like you see with the LL and REALLY see with the LR.  The stitch pulls really tight into the leather.  I can post up a picture in a few hours when I get home.  I'm not sure I love the way the stitch looks but I do like how deep it sets - no worries about fraying threads in my holsters.

Thanks. Feel free to share some pics later if you want. 

So I plan on ordering. D point, S point & LR point needles, but what size should I get for the 277 thread. 

Should I get size 24 or 25? Or both?

Thanks.

I bought a pack of 24's, 25's and 26's.  I've been sewing on the 25's but I might try the 24's with the S point and see if I like the look of the stitch better but still having it sinking down a bit.  I'll likely buy a pack of TRI/D points in those sizes as well.  As I figure it, I'd rather have them on hand if I need them than need them and have to wait for them to ship.  

The thread chart I refer to says 24 or 25's with 207, 25 or 26 with 277.  YRMV.

Thanks LiftPig. I'll get both just to have them. Like you said. I would hate to get caught with my pants down in the middle of a job/project. 

Thanks.

All you guys with Cobra class 4 machines, How many bobbins do you all keep with your machine? 

Thanks.

Thanks JLS, Is the LL point a diamond shaped needle or is it a triangle pointed needle?

I think I will get some LR needles for bags & such, just for the decorative stitch. 

I think for holsters & sheaths the LL needle would be better suited for them. 

Thanks.

yup. LL is a diamond hole.  I don't much like the "D" of "S" needles, as they make a hole I think is not as strong in teh direction of sewing, and I don't like the way it leaves "space" between stitches.

EDIT TO ADD:  I like a #24 needle, 277 thread on the "top" and 207 on the bottom MOST of the time (I have been known to sew 207/207).  The pics above were #24 needles.

I've heard their customer service & support is good. I'm hoping I never need it thou. 

yes, you certainly are.  I found the service at LMC more hype than reality.  I remember a post about it disappearing, prompting me to ask if advertisers here can get that done for them.  Meh - perhaps it's better now, it's  been a good while since I dealt with them.

Thanks. The S point needles I want for nylon straps & tarp work. I've read the S point seems to fit the best for that type of work. 

I have also heard, like you say, that their customer service can be lacking.

Guys & gals I have finally saved up enough money for a Cobra Class 4 & ordered 1 Tuesday.

Also ordered Patrick1 accessories just in case they are needed.

I will be using 277 thread top & bottom most of the time. My question is: Does anybody have photos of sewing samples with the different leather point needles? Like the D, S, & LR needle points in a #25needle. 

Also does anyone recommend any wear items/parts or additional accessories, I would like to hear about them.

I have been reading & watching lots of videos on that machine. Do any of you guys & gals reccomend any. I'll take any advice given. 

I am hoping if I run into a bind someone will be willing to help out. 

Thanks.

Buy an angled tip oil bottle like this https://allstitch.com/products/deluxe-plastic-oiler-1711

Review The videos Leather Machine Company has as well as Al Banes YouTube videos. Especially learn all lubricating points, there are more than what has red paint markings - like the linkage inside the head.

Enjoy your machine

Thanks. I'll get 1 of them bottles. Do you think a guy should have a syringe oiler as well.

Don't forget to look at whatever else is on the circuit. A 20 amp, 120 volt circuit handles 2400 watts MAX, but you also allow 20% for overhead so your continuous MAX would be 1920 watts. National Electric Code defines "Continuous" as 3 hours, I think. Double check me if you get close.

Not to insult your intelligence, but in case you or someone else don't know, here are the formulas:

Watts = Amps * Volts
Amps  = Watts / Volts
Volts = Watts / Amps

2400 watts = 20 amps * 120 volts
20 amps = 2400 watts / 120 volts
120 volts = 2400 watts / 20 amps
