My mechmate is not totally idle #48 - Sydney, Aus

I've been looking at this forum and at other CNC (mainly desktop) routers for a while. I am now totally sold on the Mech Mate. I intend to build a 8' x 4' version. At the moment I am finishing off a prototype of a hovercraft that I designed. I have attached some photos for your interest. The Mech Mate would have been quite handy in building it, but I have other inventions that I hope to bring to life using the Mech Mate.

That looks cool. Got any photos/videos of it in action.

Kobus_Joubert Mon 27 July 2009 22:55

Welcome Jude, maybe I can hook you up with my brother-in-law. He lives in Sydney and he helped a little when I was building my MM.

By the way, are those RUDDERS not a bit small at the back..

sailfl Tue 28 July 2009 00:36

Jude,

I will show my ignorance. Why aren't the fans at the back so you can see where you are going? They give you lift but don't they also give you direction?

jude Tue 28 July 2009 00:47

Thanks Guys, No I dont have any videos of the hovercraft in action. I had a heap of trouble with the Cuyuna engines and am presently installing centrifugal clutches to make starting the engines easier whilst the drive fans are connected. No, there are no rudders. The craft is steered entirely by the engine throttles. You rev up the outside fan, the higher speed of the airflow as well as the increased static pressure both cause a turn radius.

I've only just decided to do the MM build. Thanks Kobus for volunteering your brother in law, I may need his help sometime in the future. Just sent message to Rick (rnixon) for the Lasercut parts.

think this is a side wall type of craft, i am too interested in this and built a couple of crafts a few years back - lack of space made me to dismantle and just store the engine and prop :)

WELCOME TO THE MM FORUM!

Lex Tue 28 July 2009 01:42

Welcome Jude.
I see that you are not using any flexiable rubber skirting on the craft. Do you get a lot of clearance over the ground? Or is it more for beach aplication?

jude Tue 28 July 2009 16:17

Hello to Javeira and Lex,
My "invention" is a sealing system for hovercraft that is an alternative to the flexible skirt and fixed sidewall systems. Each of the blue panels are separately suspended from the hull. Each panel is also acted upon by a spring and damper. I will set up a website soon detailing the invention (my ISP no longer hosts sites for free), and wont distract you guys from the Mech Mate.

A website I set up some time ago for the Hovercraft is attached here. http://jude.idx.com.au I will update this page soon.

Wow Jude, thats damm cool. Please post vid as i'll love to she her in action.

I have roughly welded up the base table. Will need to redo some of the welds and attach lateral braces. So far everything is proving far easier and quicker than I ever imagined. There are some minor changes from the plans to the legs, etc. I chose to miter the waterpipe (using Tubemiter software) as it was easier for me to do. The hardest thing so far was transporting the X beams home. The first photo shows the X beams and rails on the 'tinnie' with Dangar Island straight ahead.
Also received the MotionKing steppers and drivers, V tyres and other bits, and have started on the power supply and control box.
I need to move this thread to 'Construction started'. Can someome help me with this.

Kobus_Joubert Mon 14 September 2009 22:36

No that is a first in MM world....Beams on Water... Well done

inventall Tue 15 September 2009 00:22

Cool craft!! I like it.

How much fun was that trip in the boat with all that wight!!

P.S. Love Sidney haven't been there since 2000:(

mrghm Tue 15 September 2009 05:08

scott land island???

jude Wed 16 September 2009 01:39

Hi Gareth, fellow Sydneysider, Scotland Island in Pittwater, is not that far from here by boat. I am on Dangar Island on the Hawkesbury River.
Hi Pete, the tinnie handles the weight no problem. The water felt dead calm that day.
Nice to hear from you again Kobus. Got to say I love your build pages.

Before someone zooms in on my welds I should point out that I redid a lot of the welds today with a 3mm arc welding rod (they dont stock the recomended 7018? rods at my steel shop) and it worked heaps better than the 2.5mm rods I used before. Also, I think I was too cautious about not overheating the beams before.

Just to update my progress. The machine is almost there. I have not painted various bits and pieces, the gear racks are not glued in, have not got the Z axis gas strut and other fiddly bits like the idler arm and limit switches are left to do. All the same I am very pleased with progress.
I used Belden CY type cable which at ~$180aus/50meters (used up all 50meters) was considerably cheaper than the Lapp brand. I will trial the machine with el chepo 1/2" router that I had.

For those that are following the progress of my hovercraft, you will notice the centrifugal clutches are installed and aligned. Lots of fiddly work to complete here as well.

BartDeckers Sun 29 November 2009 03:01

Well done Jude. Looks like a fine build.

Robert M Sun 29 November 2009 06:21

Hey Jude,
Nicely going….I can relate & sympathize with a man working hard in a confined space…. I know the feeling !!
Keep us inform of your progress, beast & hovercraft :D
Amicalement, Robert ;)

Sydney can cut it
 
My machine is now cutting and doing it beautifully. I have not got the MM decals on yet (may cut it by hand if needed) but the machine has been a goer since just before Christmas. The specs of the machine in brief are

8' x 4' work area.
Motion King steppers and Motion Kong drivers

Oops , I'll have another go with this update. The pictures should tell the story. I cut a seat for my Dory with the MM. Just to be different I bought Motion King stepper drivers rather than the trusted Gecko's, and they work fine. I am using direct drive from the steppers using 25 tooth TEA gears, and the cut quality is very good. I will attach the MM decals soon, even if I have to cut it by hand.

KenC Fri 05 February 2010 22:52

Congrats! 1st MM afloat!

Kobus_Joubert Sat 06 February 2010 01:13

Nice going Jude. Do you get those nasty Sydney spiders in your garden as well.

Gerald D Sat 06 February 2010 02:03

"Hey Jude, don't let me down.
You have found her, now go and get her.
Remember to let her into your heart,
Then you can start to make it better." - Beatles

Well done! :)

Surfcnc Sat 06 February 2010 03:53

Congratulations
 
Hi Jude - well done, that's all challenges beaten. I was wondering how the yellow machine was going after reading your thread and next thing it is cutting parts.
regards
Ross

KenC Sat 06 February 2010 03:59

When will we see that yellow machine hovers? :)

riesvantwisk Sat 06 February 2010 06:08

Well done Jude,

looks like you have a fine looking and active working going on there.

Ries

Excellent Job! A serial number is just around the corner. :)

jude Sat 13 February 2010 00:52

Can I get a number, please.

OK i've got the Mech Mate logos now, and pictures to show it. Kobus my mate, I have heard of Funnel web spiders and maybe Redbacks being around here but i have never come across one myself. I, however, tend to avoid those high risk activities like gardening. One of the critters you see around here is the Sulphur Crested Cockatoo that wandered into my office some time back. I would like to thank Gerald especially, and all the Mech Mates who have shared their knowledge and experience that made my construction quite painless. Thanks also to Rick Nixon whose kind offer to arrange the laser cutting and bending (superb parts there as well) kicked off my decision to build. I also appreciate the positive comments from you all.

Gerald D Sat 13 February 2010 01:38

Well done Jude!

Gee, using the plans for a bird-feeder took some swallowing. :D

Kobus_Joubert Sat 13 February 2010 03:28

You can be glad the bird is still FEEDING...:D

Enjoy the ride Jude..
