JR, I am glad that it worked out for you. When I had my 202 failure I contacted them asking for some info, but up to now have not heard a word from them. For us on the other side of the world it is not that cheap to send it off in the post, but maybe I should try and see what happens.

On the other side I am very happy with the UIM units I am running now. I did had to buy a new transformer ( lower voltage ), but I find my steppers running cooler and I cannot see any difference in speed. Maybe in top speed jogging, but cutting speed is just as fast as what I feel the MechMate can handle without jumping the rails or skipping steps.

Maybe I should post those 202's to you and you send it on for repairs for me

I read most of your build diary and you are an inspiration! It is sort of funny that lumberjack Jeff is on one coast with the most frugal system, and you on the other coast with the most detailed system, and you are both building boats!. I don't mean to insult either of you. Both builds are impressive. I have a couple of questions that you can feel free to answer or not.
1. Are you making a living with the MM?
2. Did you integrate it into an existing buisness?
3. Did it fill an already identified need?

And last but not least. If I get more serious, can I come see you and your MM at work?
Thanks,
Roger, (near Charlotte)

Now Mr J.R. Please explain how it all works. Is that big golden wheel the chisel ? Does that move towards and away from the workpiece. Then I see another stepper to move it left to right.

do you then just spin the workpiece at normal lathe speeds ?

1. How is the finish of the cut
2. Do the customers like it
3. whats the time saved b/w manual and now cnc
4. what RPM are you spinning the cutting wheel at
5. what program do you use to generate the g code
6. What diameter of wood (minimum and max) can you turn on this??

Hi JR,

Nice build, What did you use for the movement, Ball screw or Acme, How is the accuracy.I assume the motor to be a 2 Hp 2880 RPM one. Whats the finsh you are getting, do you sand then after turning? Love to see a video of your machine turning wood.

Regards

Vishnu

I want to be JR when I grow up.

West Satsop Boatworks is just getting started, but we've delivered two 19' boats to our main client.

Like JR, our niche will be making kits.

1) not yet, although we do now have positive cashflow (yay!)
2) no
3) the business was started up around the MechMate, and the relationship my business partner has with Samual Devlin.

As of delivery of the second Pelicano, the MechMate has paid for itself. I can't thank Gerald enough.

This was my first attempt at CNC ....... 2005?. It was built on a shoestring budget. The rods that the carriage travels on are "1 inch black water pipe" just like it came off the shelf. The steppers directly drive regular all thread rod (I will be changing the Y axis to rack & pinion (problem with the rod whipping during jogging)). The motor driving the 8" chain saw cutter is .25 hp 1725 rpm w/ a 1:1 belt drive. The material turns very slow .... around 180 rpms. I can turn almost anything with this that I can turn by hand, however some pieces (depends on design) require some hand work to complete. It's accuracy is much better than almost all wood turnings done by hand. The software is "Mach3" and it is used as if it were a mill with no z axis (X is dia. and Y is length). The cam software is "Sheetcam" and does need to be fooled a little to make it work.

Kenc the wood chips are contained by the shower curtail

Irfan
1. How is the finish of the cut? Very easy to sand
2. Do the customers like it? What customer wouldn't like CNC
3. whats the time saved b/w manual and now cnc? It does 90% of the work while I'm doing something else
4. what RPM are you spinning the cutting wheel at? 1725 RPMs
5. what program do you use to generate the g code? Sheetcam
6. What diameter of wood (minimum and max) can you turn on this?? .5" up to 12" The lathe is an old Delta (pre Rockwell) 6" X 36" with this thing bolted to the back of it, this way I can still turn by hand

Thanks everyone

Roger and Jeff .......... I want to be like anyone making money with his CNC

If I missed anyone's question please point it out.

Johan the cutter is homemade, it is a chain saw chain (smallest you can buy), the disc I turned on my metal lathe.

Thanks Heath

Hello everyone, its been a while since I posted here but I read the forum on average once a week. I need some input from you guys. I'm cutting parts for a small business using 1/8" X 4' X 8' pvc (they supply material). We cut around 10 sheets every few weeks to a month. There are several different stock sheets, each sheet has around 20 pieces. Tell me what you think it's worth per sheet to cut this job. Thanks for the help .... J.R.

JR,
PVC extruded sheet cuts VERY quickly (1/2" pass with 1/4" spiral @ 280-400ipm) - and makes one heck of a mess. Just remember to wear a good filter/respirator mask if your in the little shop.

When I was cutting 3/4" PVC for cooler inserts at the ball field (to separate coke bottles), I charged 50 bucks a sheet to cut it, or 400 for the day if it was a large, repeatable qty.
It takes more time for clean up than it did to cut sometimes. Static cling!

Good luck my friend. Good to see you here.
Sean
