Awhile back I posted some pics. of a mount i made for 100 vdc motor that I had. Some pointed out other ways that were better so I have redone and thought I would show my progress and look for more feedback

As you can see there was no offset in my first mount.

This is my new mount.

looks like a real beast...

whats the amps output ? and what size of blade do you plan on using?

The mounting looks more robust with the pipe clamps. It may be the photo, but the angle on the tail looks a little larger than the 18 to 22 degrees or so I'm use to seeing for these, but as long as the forces between the wind on the blades and the weight & angle of the tail workout all is well. What angle did you use? Rich

I think it is OK.

It looks quite robust.

You'll need to experiment with the tail weight...

I fail to see a reason why you should complain about something that doesnt concern you. ;-)

I have a set of Art's blades that I am going to try,don't know yet what amps will be but if i spin the shaft using my hands shows almost 100 volts so i'm hopeing for good things.

Do I go in the house to watch the hockey game..or stay and work in the garage.....let me think, hence the tv.it is 12 volt and runs off my battery system.

Hi Rich, was thinking of putting a set of the blades i got from you on but don't think I will need those high Rpm's :-) I'm not sure of the exact angle and most of my work is trial and error. I do have Hughs book and tried to follow it for the angle.

I used 21/2" pipe and 3/8" plate, the 6" pipe clamps are bolted and tack welded to the blade also have a heavy duty tapered bearing for inside the mount so it will pivot nice and smooth.

Very robust. Nice piece, hope it works out well.

T.V? who cares?

Looking at your new mount, I think that you should place a gusset between the motor and the yaw tube. With the weight of the motor that far out unsupported,with any vibration the motor mounting plate could fracture. And that would not be good!

Good luck!

I'm glad I didn't post a photo of MINE! ;-)

Thanks for the idea! the motor does weight about 40 lbs. in it self so I am going to take your advise.

Hi,

here in the picture is something I wanted to do for your mount:

Now that is what I call helping a fellow out,pictures sometimes say it lot better then words. Thank you!

It looks very nice! When you add a gusset here and there, it will be stronger. Don't think the tail would need it (though personally I would add it), but the motor, I definitely don't feel comfortable about it being mounted like that. It could use a bit of reinforcement, I think.

Will be building my own mount soon too. Will be made out of stainless steel though. I know it's a bit more expensive (not where I shop, the scrap dealer ), tougher to work with and has lower strength.

However, the corrosion resistance (and thus, need for maintenance) would be reason for me to go that route.

I'm surprized that I've never before seen pictures (as far as I can remember) where some built his mount out of stainless steel (apart from Joe WXYZSCIENCE's downwind turbine, which is partly made out of SS, but has a quite different design from the standard furling mechanisms).

Peter, all my metal parts I give a good coat of primer and rust paint for metal then when I finally mount them out side also give them a coat of LPS 3 heavey duty rust inhibator,this stuff is like a thick coat of wax that sets up quick and lasts a long time.You have to scrape it off if you want to remove it. I ground down a piece of plate to bare metal sprayed some LPS 3 on it and even after 6 months outside the metal is just as shiny as the day I put it out so this stuff works good.

dinges · « **Reply #18 on:** July 10, 2006, 07:42:04 PM »

Understood, Ken.

My remark about the use of stainless steel was a general observation, not criticism on your construction. I know that proper treatment and painting of steel can rustproof it.

I however, like the shiny look of stainless steel

richhagen · « **Reply #19 on:** July 11, 2006, 04:56:51 PM »

Peter, the material costs more, which is probably part of the reason, and you have to TIG weld it which is probably most of the other part, something which I have not tried. It would require very little maintenance though when finished, as you pointed out. Rich

dinges · « **Reply #20 on:** July 11, 2006, 06:19:01 PM »

TIG welding is not a problem for me, however, SS can be welded very well with an AC buzzbox (DC being nicer), as long as open voltage is over 70V (though my dad used to make good welds with a 40V welder; not easy, but can be done).

So, anyone that has the equipment to weld plain steel should be able to weld SS (with practice & the right electrodes).

Material cost is of course still an issue.

Peter.

kenputer · « **Reply #21 on:** July 11, 2006, 07:12:03 PM »

Peter, no problem I was just saying what I do to protect the metal.

Ken

kenputer · « **Reply #22 on:** July 11, 2006, 07:20:54 PM »

I got around to adding the extra support to my mount and the worst thing about it is I have to repaint:-( This will take away any worries about the mount being strong so well worth having to repaint.

A little grinding and paint it will be good as new.

Thanks

Ken

who8myrice · « **Reply #23 on:** July 11, 2006, 08:59:36 PM »

looks great, and with that added support, it should be very sturdy. but i was wonderin, hat kind of motor was that? its very large and i have been looking for something right around that size.

Thanks a lot

-Steve

kenputer · « **Reply #24 on:** July 12, 2006, 04:58:59 AM »

Hi Steve, the motor is a GE PMDC, i have 1 that is 100 volt and another that is 200 volt picked them up on ebay under $50. each.
