I have the original wooden Printrbot Simple.

Yes, it's plastics - PLA. I have an old printer - got it about 4 or 5 years ago and built it from a kit. But, it continues to do what I need it to so I haven't been compelled to upgrade.

I haven't heard of wax prints - the wax would be to uncontrollable at high temps (it would take too long to cool off and therefore wouldn't hold it's shape I would think). I have heard of people printing molds directly. Although, I would imagine that the melting point off aluminum is pretty high.

No spacer came with my spindles so I decided just to print my own. Curious to see how they hold up.

does look interesting Yeah, I think that design looks interesting too. I am hoping that you get the info you need as I am interested in seeing you build this one.

Looking forward to seeing it progress. Thanks for taking the time to post.

I am equally new - building my first kart. But, thus far, I have been buying from OMBWarehouse. They have a flat fee for shipping - $7.99 - which I think is reasonable. And, any order over $99 ships free.

I have heard that - especially with respect to online orders. I haven't heard that with respect to phone orders. In fact, I do my shopping online, then getting the online site to quote shipping, then call in with the same items. When I call in, I have always gotten a lower shipping quote than...

Rant coming... Every time I look to buy something from BMI, the shipping ends up being way more than the part. How do they stay in business? I understand that shipping costs have gone up a lot in the last several years. And, yes, I have been incredibly spoiled by Amazon Prime's free same day...

Yeah, I am not too impressed. I put my fingers into the center of the rim on each side to "grip" the bearings and then gave the rim a spin - I don't even get 1/2 a revolution. Very disappointed with my purchase.

How do I grease them. I haven't yanked on them but are they easily removed from the rim so that I can get at the bearings to grease them? Thanks

I purchased some 4" rims with built in bearings from OMBWarehouse. They came with a built in grease fitting. I assumed this was for greasing the bearings. But, it appears that the bearings are sealed. The grease fitting opens into the center section of the rim between the bearings. So, if I add...

Hello everyone. I am new to the forum (first post a few days ago) and new to go karts. I am some building skills - wood, mechanical, electronics, etc - but no metal working skills. Hope to change that in the new few months as I am always looking for new things to learn. And a new project is my...

Thanks for the feedback / suggestions. Yes, I plan on taking a welding class first. There are several metal fab spaces in town that teach welding. Then, if I think it's for me, I'll get a quality welder. With all my random interests, I am sure I will use my welding skills/equipment beyond this...

Thanks ultralight01. The "replacement" of karts by quads and dirt bikes is something that I have noticed as well. I was super surprised at how low cost they are becoming. But, personally, I feel ok putting my daughter in a yard kart but will not even consider a quad or dirt bike for her for...

I am new to the hobby and have been looking around for only a couple of months. I am interested in building an electric yard cart for my 8 yr old daughter. I am comfortable with my mechanical and electrical skills but I don't weld. So, first things first, I need a frame. The only one I could...

Julian, Looks great!
