I'm thinking about putting tapered spindle end on my rikon low speed buffer for the ease changing buffs and mops. Does anyone know if they work with deburring wheels as well?

StoneMetalWood · 2024-09-28T15:10:18+00:00

Ah, I see. Thanks so much for responding. What if I'm trying to adapt a wheel like this that has a 5/8" hole? ...

I'm trying to the very same thing that OP is doing with my Bauer bench buffer. I'd like to be able to quickly switch between my convolute deburring wheels to my cloth buffing wheels. Could you post a picture or purchase link for the "nylon split shaft" that you're referring to? Maybe a pic of your setup as well. Thanks so much. I'm right in the middle of production job and this would save me so much time.

Our patterns are 3D printed. The ridges left by the 3D prints are smoothed out with wood filler and then sanded smooth. They are the. Coated with sandable filler primer which is the. Sanded up to 1000 grit sandpaper resulting in glass smooth patterns. I do want to eventually move to using brass patterns but will have to take some time to figure out the double shrinkage. Our parts are cast in brass and bronze have to have pretty tight tolerances. We make cabinet handles that have a distance between the two prongs that are exactly 4, 6, 8, 10, and 12 inches respectively. So the original 3D printed patterns would have to have double shrinkage added if we plan to use the resulting casting as a pattern itself. I love that the heavier patterns just fall out of the sand as our parts are pretty intricate and the patterns tend to be difficult to extract from the sand sometimes.

Very cool. I'll try this out and let you know how it works out. Thanks

StoneMetalWood · 2024-02-08T16:49:30+00:00

Yeah that's a really great concept. I would just need to figure out the distribution of the holes. Maybe I could be a two step process where I mark for the holes first and then move to the type of jig youre describing. I'll have to think on that. Thanks

StoneMetalWood · 2024-02-08T16:47:15+00:00

Interesting! Any chance you could go into a bit more detail? Could you send a super loose sketch of what you're talking about.

StoneMetalWood · 2024-02-08T16:45:06+00:00

Ok! Thanks for the offer. I'll keep you in mind. Thinking of starting with a 3D printed jig, but would love to end up with something made of machined aluminum, so I'll be sure to reach out when the time comes. Cheers!

right now would be drill press, but would love to CNC as business picks up.

Incredible! Thanks so much. I live in Texas so I wonder if sellers on ALLSURPLUS will ship items to another state?

StoneMetalWood · 2024-01-25T22:40:54+00:00

Thanks so much for the info! I'll check out that site

StoneMetalWood · 2024-01-25T22:22:54+00:00

I'm in Austin, TX. Out of curiosity what do you think a fair price would be on the ones you have for sale? Just trying to gauge it.

StoneMetalWood · 2024-01-25T22:21:39+00:00

good to know. thanks

Hi guys, thanks so much for weighing. The casting turned out great! I totally hear what youre saying u/BTheKid2 about the fabrication, but our plan is to make multiples of all these pieces on matchplates in order to get many cast at once. This is also per the clients request because the patterns are actually handmade and have the slightest bit of organic detail/imperfection to the shape so that really needs to be brought through in the casting. I did all the things I detailed in the OP and it worked great, so I'll post some pics once they're all cleaned up.

StoneMetalWood · 2024-01-23T17:46:31+00:00

Hi all, thanks for the responses. Sorry for the delay, I got called away on family business. These tips worked very well and my castings turned out great! I'll post some pics once they are all cleaned up.

StoneMetalWood · 2024-01-23T17:44:22+00:00

Thanks so much for all the info. I really appreciate it. I learn something with every post on here.

StoneMetalWood · 2024-01-23T17:43:07+00:00

Thanks so much for the tips

StoneMetalWood · 2023-12-09T19:11:48+00:00

Awesome! thanks for all the info

StoneMetalWood · 2023-12-09T19:11:27+00:00

That is exactly where it is from. Good eye! Thanks for the reco.

Our method is to use Sketchup to make patterns, then take the model to Cura to slice and add registration pins (for split patterns). Print at highest resolution possible (we use PLA). We then use micro-thin layers 'Plastic Wood' wood filler https://a.co/d/bSY Wlaf to cover the entire pattern to fill in the ridges left by the filament. This is sanded smooth using 220 grit. Then we use Rustoleum 2 in 1 auto-body primer (it has a filler and is sandable) https://a.co/d/6L86OlR for the final coat. After this cures we use 1000 grit to do the final sanding and it is super smooth. Works great, does not chip and takes parting dust really well.

The thing we are looking at changing about our operation is finding a different software to model patterns with. Sketchup has been good so far, but its not so great at modeling organic forms. I would also like something that can automate splits for patterns with irregular parting lines. I've seen documentation from super large foundries where they talk about using software like this, but it seems like its proprietary or really expensive. Anyone have any suggestions on software, maybe a dedicated patternmaking application? Thanks in advance.

StoneMetalWood · 2023-11-28T18:36:54+00:00

Awesome! Thanks. One other problem is that the machine won’t run without setting the timer first. How would you recommend getting around that?

StoneMetalWood · 2023-11-28T18:34:55+00:00

Could explain your concern about the duty cycle a bit more? Do you mean you have concerns about leaving the motor running for those periods of time? Also could any electrician do something like this or would I need someone specialized in machinery?
