    • The Dash 9 is probably better served with a puller that presses on a screw in the half shaft. The taper fit probably requires this.


      If you used a puller like the USAT one, you would most likely rip the metal half axles from the nylon gear and strip the small holes that hold the half axle to the gear.


      In the picture below you see a half shaft removed from the gear, and the small screws that attach it.

    • I’m just using generic PLA for both this and the gauge blocks.  It’s plenty strong for both.

    • Cool tool, Eric, thanks for sharing.  I don't know that i need it right now, but I do have several of those locos so may need it one day.  I'll download it for future printing.  What filament are you printing it with?

    • Marco: this should work for any of the USA Trains engines. I imagine it would work for the Aristo Dash 9, but I’ve never seen one of those axles. I’ll connect offline about getting one of these to you.

    • Hi eric how are you would you also be kind and sig me up a set like thet for the SD70 and the GP38 is it also good for the F3’s?  Do you happen to also have a wheel puller for the Dash-9’s?  I know here on the forum Greg has had whee pullers for the dash 9. Please send me an invoice for the wheel pullers.  Thank you

    • Eric, That's awesome.    Sign me up please.    Would you be so kind and send the PayPal link to my email address as you had done for the two jigs?    I will gladly send you the $20.00 asap.    This is great.    Now I will have a complete USAT wheel set repair kit.    And the whole works can be shipped it one package.    Thank you Eric.  Mark Betlem

    • Yes, I'd do the same deal as the blocks: $20 shipped.

    • Really cool.....again. That device looks very helpful as well.  Any chance of you offering the completed version of this for sale also?  We could pick up the screws locally.

    • Here's another new 3D gadget for you.  It pulls the wheels and gear apart.



      Here's the file for printing:

      The linked file has a larger wheel cutout, sized for the SD70, which I believe is the largest diameter wheel.  The cutout for the gear is sized for the larger 2-axle gears.

      The jig requires three #10 screws and nuts.  I found with fine thread screws, I could turn them by hand, even with gears that hadn't yet cracked.

    • Now the truth is coming out, everyone thinks Devon is producing all this great modeling on his own, but nope, he has a whole crew of little elves doing all the work while he sits back, gives orders and takes all the credit   Gives a whole new meaning to "Butt Modeler" doesn't it?

    • I also have club members printing for me as well.

      I have considered this as well Bruce

      He's got Dan printing for him, better to use his talents else where.

    • If you're just looking to fool around a bit with making some little stuff, you MIGHT consider getting a 3D printer instead.   They can still be frustrating, but it's really cool to be able to watch it print a part.  If you're not great with 3D design, you can just download stuff from Thingiverse and print it.

    • I appreciate everyone's comments and considerations. Still in the fence. I cant afford quality milling equipment for a few one off parts. Just cant justify it. 

      As far as multi tools, I own THE multi tool. A Shopsmith. Does it compare to my stand alone equipment, not a chance. But is it useful, allows me to do things I otherwise would not get to do. 


      I havent decided to pull the trigger. But it NOT a case of not buying this or saving up for better stand alone equipment. It's a case of buy this or nothing at all. Milling equipment is a too expensive luxury I dont have 


      I asked because I am leary of these sorts of things and have had bad experiences with these sorts of purchases. But on the other hand I have had some good ones with cheap tools allowing me to do stuff I otherwise wouldn't. Tough call. 


      I do thank you all for the input. Its sincerely appreciated. IF i buy it I will let you know how it goes.

      Thanks. I am think I am gonna give it a try. The main thing i see myself doing with it is turning an milling brass and plastic for detail parts, cribbage pegs, etc. Nothing precision. 




      I have to agree with Rick Marty and his comments about multi-use tools. Bottom line is that they are not sturdy enough to give you ANY kind of precision :). Save your money and buy individual tools for your work. A simple hand drill would be far better than this combo tool. You WILL be frustrated beyond belief with the results from this combo machine or ANY combo machine. Really a waste of good money. I am a retired tool&die maker by trade, so you know where I'm coming from :). 

      I built my Gene Allen ten-wheeler (1/8th scale) using a mill/drill combo machine. It weighs 800 pounds and yet it still flexes on heavy cuts. But I know how to use it and where I can get precision down to 0.001. But it takes experience to do this. The average hobbyist who hasn't done machining before, won't know how to get precision out of ANY in-expensive tool. I only use the mill/drill for milling ONLY. I have a separate drill press, 12X36 Clausing lathe. Another combo tool I have is a Shopsmith. Bought it brand new in 1978. I never use it as a table saw. I use it in combination with the Shopsmith bandsaw accessory or as a nice drill press for large work. The ONLY reason I have the mill/drill and shop smith is because I don't have the room in my shop for the full-size mill (Bridgeport). As it is now, I am cramped for space and it's 500 sq. ft.! Full-size Delta contractor shaper with 1-1/4 shaft, full 12 inch radial arm saw.

      Bottom line is that you can find individual tools for specific jobs. In fact, Amazon just sent me an email showing "reconditioned" tools available for about half the cost of new. They come with warrantees, too. Just remember exactly what you said at the start "I know you get what you pay for, but.......". And in tools (any tools), this could not be more true :). You mention that you want to mill or turn brass and plastic....don't be so cavalier concerning these materials :). Without being able to adjust speeds or only 3 or 4 different speeds at your disposal, you will be frustrated quickly. Please "rethink" this purchase :).

      Bought mine for exactly the same reason, couldn't justify to myself the purchase of a lathe for some maybe/might happen in the future projects. 

      Bought mine years ago from Hobbyking for about $50 and have still not used it in anger yet (found a drill press at a garage sale).  Matter of fact I only just pulled it out of a cupboard and added it to the removalist pile in readiness for my move to my retirement abode.

    • Good enough, we can compare frustrations er successes!
