Ok back to tires,,,



I have the four pieces printed, still have to glue them together, sand, fill, do whatever to make them mold ready. I did find alumalite resins and mold making supply. I'm not completely sure what products to use but an email to them and hopefull they will help me out. I know why custom tires are expensive. Any of the materials use to make tires this size are not too bad for small parts but I'm gonna need the gallon size and it like 100$ so I could easily see something like this (each tire) costing 40-50$ by the time mold is made, work in making it, the actual material for the pour, ect,, as the saying go " ya gotta pay to play"!!! But if I come up with something that works I may be able to make a couple more.

Ahh right away, 8" aren't big enough!!! Lol!! Guess you have a 797 in mind? I'll work the bugs out with these.

The way my threads have been going today I have some off the cuff comments about the cat on your face but I'll keep them to myself. Your thread has gotten back on track so we'll keep it that way.

The tire looks wicked! You've inspired me to ask Santa for a printer at Xmas. I won't know how to use it but it will be fun to watch it melt weed eater string into blobs.

Looks like a great mustache hu? Although not at the theme park, no rides available. Oh derailed again, guess I'll have to scroll up a bit and watch the video again. Lol!!

For me, the printer is inside the house and not in garage, out of sight out of mind. Several times I have sat in garage thinking how nice it would be if I could just whip up some complex/simple part,,,,,, and then I remember ,,,I can,,,,, I just have to re learn how to use the design program. I did switch to autodesk fusion 360. It's a trial for 30 days and then 300$ a year, cloud based stuff but does all the things the 3000$ software does that I would need. But....., another thing I have to learn. A lot of features, definately have been watching a few tutorials and realizing if I can get a pretty good working knowledge I would be set and able to make whatever I need.

You have my attention steve. I would love to see you build a rope shovel!

Cool looking Tires Cooper keep up the good work looking forward to the end result.

[speedy8305]

Hey Cooper you can get fusion 360 for free for life check around youtube. I did and now I have it on my comp for free I think you have to register it for hobby use or something else dont remember but check it out. just letting you know

[bigford]

around page 100 of this thread you will see cooper caterpillar open fer bizz
with supermario working for him!!!!

[Bo Wallen]

You're right BigFord !!! What a team that would be. Both kids doing amazing thing for sure. Can't wait speed it up please.

[modelman]

The tire looks great cooper. Should mold well. And yes, a tire this size will be expensive!!

[Cooper]

Humm, tube/ tubeless tires?!?! That would be cool!! Maybe for the next project and some more experience on casting stuff .

Well I started welding the tire parts together.

Made a center piece for glueing the parts together. The aluminum was just shy of being able to use to make the rim. So have to get some more stock.




And the shop fox kept wanting to be nosey so he was sniffing the acetone I was using to glue tire with.



( just for the record the cat wasn't huffing glue. Don't want an animal cruelty case!)

[speedy8305]

Looking good Cooper Looks like when you finish it will be a winner.

[Cooper]

Oh and picked up a vacuum pump and harbor fright. Got it for de-gassing molds and casting resins. Quite a few times in the past I could have used one (and some gauges) for repairing/charging air units so it's not all hobby based purchase

Back to the double acting stage cylinder, we tried to come up with a way to feed oil from the bottom but were never able to feed oil from that end for retracting. But I'll keep watching to see how you do it.
Aren't tires fun I did a set for my Letourneau L2350 like you I made a master using some old tires I had then coated it with about a 1/4" of urethane, ( Pink color) I then made 2 plaster aparis (spell ?) outside cavities, to hold molds from deforming. Next I made some urethane foam center cores suspended by a solid core where rims go to save the amount of tire material required. Procedure, place bottom mold in place with center core then foam, then top mold with ports to but in tire material, plaster parts had pins to make sure they lined up. Once cured opened molds pulled out tire trimed off ports and placed this side on the inside when mounted on model. Turned out great tires were made of Smooth On products and with foam core I didn't need to put anything inside tires to stop compressing by models weight. hope this will give you some ideas. Oldguy is true all my friend have been retire 10 years or more.

Thanks again earl, I probably won't get to mess with this stuff till after weekend. I'll try and make something up for what I'm thinking for double acting cylinder. And yes I have been thinking of some sort of core for these as a lot of casting material will be needed. And I have to make 6. Figure this is the first of a few mess ups I'm sure m
