3D Printing with Fire and Iron | Making a Solid Multifix Toolpost Riser

Today, we're designing and 3D-printing a casting pattern to make a solid toolpost riser for a Multifix quick-change toolpost on the Grizzly G0602 lathe. The plan is to delete the compound and replace it with a solid block of cast iron to improve the rigidity of the lathe and add a little style and flair at the same time. We'll design the casting pattern in Fusion 360, print it on the Elegoo Mars 2 Pro 3D printer, and send it off to the foundry to have it rammed up and cast in gray iron.
The casting will be done by Clarke Easterling at Windy Hill Foundry: windyhillfoundry.com/

James, you do excellent work with everything. I'll bet you have short learning curves. Now I have to wait till you get the casting back and do another video. Your tutorial on 360 is at a university level. Bravo. Thank you for sharing.

[@summerforever6736]

Yes he is an expert to me

[@ZPositive]

I did the compound delete on my 14x42, and it changed my life. It's amazing how much the rigidity changes the lathe's personality. In 5 years since I did the delete, I've only needed to swap back to the compound twice.

[@thejoetandy]

What sort of operations needed you to swap back?

[@ZPositive]

@@thejoetandy a precision taper and picking up an internally cut thread for cleanup.

[@joergengeerds360]

cutting threads with a STP is easy/possible, or not advisable?

[@ZPositive]

@@joergengeerds360 cutting fresh threads with it is no problem at all. Especially with large external threads, the added rigidity makes the experience downright pleasant. Picking up existing threads for cleanup can be difficult with the STP, but not impossible. Nowadays I loosen the tool from the tool holder, align it with the existing threads, and re-tighten the tool into the holder.

[@DavidKutzler]

Parting was a nightmare on my 7 x 16 inch Chinese lathe, especially with "gummy" metals like brass. I machined a solid tool post riser out of a length of 2 x 2 steel square stock to replace my compound, and my parting blade goes through metal like butter. I only replace the compound on the rare occasions when I need to cut a tapered feature.

[@danbreyfogle8486]

Clark sent me over to see you make the pattern and now I am hooked! I am an old woodworker with no machining skill or equipment so I watch our of curiosity alone (and envy at the tolerances you hold compared to woodworking). I'll be watching your channel as I subscribed.

[@dizzolve]

man you're so fluent with that software. I wish I knew it that well.

[@David_Best]

Having designed and produced lots of solid tool posts for small-medium lathe owners, I feel compelled to offer a few comments. But first I’d like to really commend you for advocating the use of a solid tool post (plinth mounting block) in lieu of the compound on small 10-13" lathes when the compound is not required to profile tapered elements. Indeed, the compound on these smaller lathes is the root of rigidity limitations. A solid tool post setup will drastically improve rigidity, provide for increased material removal rates, and tighter tolerances - not to mention lowering chatter. Additionally, I love how your videos wander off in all directions (custom iron casting, producing a casting plug (mold) with the 3D printer, designing the mold in Fusion 360, etc.). Thank you for doing more than showing us videos of peeling off chips !! With that said, I would like to offer a few comments on the subject of solid tool posts that may be instructive to your viewers. 1 - While the Multifix QCTP would be ideal if starting from scratch, the benefits of a solid tool post are equally applicable to Aloris-style QCTP setups. It is not necessary to convert from Aloris, and all the implied tool holder change-outs, to gain the benefits of a solid tool post mounting system. 2 - It’s worth emphasizing that if the height of the solid tool post plinth block is identical to the height of the compound, either can be swapped out for the other with NO impacts on tool height adjustments. 3 - While I admire all the educational value of doing a custom cast-iron plinth block, this effort is not necessary to achieve the benefits of a solid tool post for most users with 10-13” lathes. Indeed, in my own experience, 7075 aluminum, or a block of 1018 steel is perfectly sufficient for lathes in this size range, and a chuck of such material is typically available (even from McMaster) for $100 or less. Having said that, if you were putting 5 horsepower into a negative rake Trigon insert tool, cast iron might indeed prove beneficial as the plinth block material because of it’s shock-absorption characteristics. Thanks again for a great video.

[@HM-Projects]

Yes, that's what I ended up doing. 1020 mild steel that I had around worked very well. One thing I didn't do but will need to is modify it to pinch the tool post in one corner to reduce the reliance on pure downward pressure.

[@v8Mercury]

Thanks for your comments.

[@p.t.anderson1593]

I use F360 for my LS Crossfire Pro plasma cutter to make random stuff for people. Even in 2D, text can be a challenge... I just about spit out my mouthful of dinner to laugh when you mentioned the challenge of making the raised 3D lettering on a compound curved surface. What an understatement! From my perspective, your Fusion 360 Fu is very strong...

[@laurawerner]

FYI, the "Fusion 360 School" channel has some good videos on how to emboss / deboss text onto a surface with compound curves. There's no simple way to make the embossed features perfectly aligned with the compound surface, but he's come up with some clever techniques that often look just as good. It's a great channel for an intermediate F360 user.

Very nice, looking forward to seeing the finished part. You may want to print plugs to go over the mounting screws to keep swarf out. Cheers

[@cavemaneca]

My first thought upon seeing your test with the 3D printed parts was that those bolt holes will fill up with swarf and oil in no time. If you can print flexible filament, maybe a contoured rubber-like plug to cover the bolts would be a good addition?

Very cool to see you do this mod as well, in your own way. When I built mine for my newest lathe, I was lucky enough to find a seller that sold large slices of cast iron, they were 200mm diameter by 60mm thickness and around 80€. So I just milled the whole thing out of solid.

[@markfletcher6511]

Once again you have delivered a fun to watch and informative video. Every time you talk us through a Fusion 360 session, I learn a lot. Showing how to make "finished model" and the "casting model" was fascinating. As soon as I finished watching I jumped onto the Windy Hill video to see it come to life. The only downside is having to wait for the machining video.

[@CraigLYoung]

Thanks for sharing 👍

[@5tr41ghtGuy]

James, I have the same lathe, and you can mostly solve the compound flexibility problem simply by rotating the compound collar around backward. Of course, then you cannot see the protractor. My permanent solution was to make a new collar with a much thicker bridge over the protractor. This works so well that I couldn't imagine suffering the inconvenience of deleting my compound.

[@greg4367]

Always learn something from you videos, today even more then usual. Thank you.

[@codebeat4192]

Very talented.

[@mosfet500]

Thanks James, you sure are good with some of these programs. I made a solid tool post and deliberately machined the height lower so my Aloris tool holder would allow the full range of Aloris tooling, which it now does. The reason I didn't go with an indexing holder is the individual tool holders are more expensive and I have about 30 or more tool holder. I just loosen the Aloris and turn it to the angle I want which doesn't happen very often. I like that once the Aloris is square to the lathe I have the 90° set instead of having to change the index position.

[@FullSendPrecision]

I dont know how I'd live without a compound.

No kidding. Cutting tapers would be ... difficult.

[@scratchbuiltdesigns]

I have a size A Multifix from AXA and apart from the 20mm mounting hole it has two 6.0mm alignment holes for dowel pins. I assume yours have them too. I highly recommend to use them to avoid any movement of the post. If you add a few more holes with the right spacing, you can even increase the 40 times 9 degree positions of the Multifix down to 1 degree if you wish by rotating the post from dowel to dowel...You would have to turn a stud for the 20mm center hole to rotate around though, but I believe you will do that anyway to achieve a reapeatable mounting position of the post on the riser...

[@Clough42]

Yeah, I haven't decided exactly what I'm going to pin. I have the correct reamer, though. Some have suggested pinning the riser to the cross slide as well.

[@sebastiengomez3855]

you can use the manufacturing space in fusion and create a manufacturing model. any changes made on the manufacturing model does not change the original design, however changes to the original design will take affect in the manufacturing one. This allows you to have different versions of a model (u can make as many manufacturing models as u want). This is great when you have multi step machining (i mean goin from one machine to another) and you need to derive a new "stock model" to work on. this is essentially what you are doing, you are starting with your cast model, and need to add all the features that couldnt be cast etc.

[@stancloyd]

I don't have the software, so when I built mine, methods were old school to say the least. Having also struggled with a source for appropriate cast stock, I bought a new cast anvil from Harbor Freight and sawed and milled away everything that didn't look like the finished riser block. Because I wanted to thread the usual way and the upside down Joe Pie way, the fuss factor for height was a bit extreme. I thought about reaching out to Clark, but the anvil only set be back about 70 USD.

[@gbspikyfish]

I have one of the little 7x12 mini lathes and made two different blocks to replace the compound; one similar to this video (though just a small block of steel), the other is a little longer and allows the toolpost to be mounted further away from the lathe centre; as that allows a tool to access the outside edge of 6" diameter disk. I haven't really missed the compound on that lathe, though since adding a Colchester Chipmaster to the workshop I have ended up using the compound on that machine quite a few times.

Enjoyed the process presentation particularly the Fusion 360 part. The 3D printer was intriguing, my kids want one and I need to find out more about it in order to get a system that will work for them. You just kicked up the whole youtube tech campus up a couple of notches.

[@Clough42]

I think getting kids started with 3D printing is a great idea. It can be challenging, though, if you want to do more than download and print anime characters. The biggest impediment I've found is designing parts to print. The software can have a steep learning curve, and designing for the limitations of the print technology requires some understanding of how the part is going to be printed (orientation, support, etc.). Filament printers (with PLA) are pretty user friendly, as long as the printer is decent and you get the bed adhesion sorted. Resin printers are capable of much higher resolutions, but the resin is messy, stinky, and toxic. It requires a lot of discipline to keep from getting it on your gloves and then spreading it everywhere. Some kids could handle it easily. Others would immediately tip a liter of resin into the carpet. I'm not even sure how one would clean that up. :)

[@KizmitMakesIt]

Hi James, interesting and informative video as always - thanks for that! When designing parts in Fusion 360 that need "tweaks" in order to 3D print well (or in your case caste), I usually design the "perfect world" component first, then derive a new part (or component) from that original component and make any design tweaks necessary to enhance the 3D printing of it. Any design changes you make to the original part can flow into the tweaked part easily and you don't have to futz around with the timeline as you were doing in this video. If you haven't looked into derived components, it's worth a look.

[@mp6756]

I really like the idea of the solid tool post block. I have had a conversation many times with fellow machinists and I know it isn't highly agree upon and I do understand the variety of options. When single point thread cutting the I believe the proper way to advance the depth is by setting the compound slide @ 29.5° and advancing with the compound. Do you subscribe to that method and if so are you willing to abandon that process by eliminating the compound. I am an older guy and I use the compound slide when threading on my little manual bench top machine at home. I find it cuts a much better finish on the thread given the lack of rigidity on my little bench top machine. I think it has a lot to do with the lead screw and half nut as I disengage the half nut while cutting threads I'm not big on running in reverse to start my next cut. I just found your channel and I really enjoy your thoughts and deliberate explanation of your process. Thanks I would love to hear your opinion on the single point thread cutting. I'm already a fan of your work.

[@aceroadholder2185]

Mike, I also cut threads like you do using the compound slide. There are two reasons I've never seen mentioned that make this method preferable over plunging straight in. First, if plunging straight in you have to keep track of the cross slide setting for each pass whereas if using the compound you only have to return the cross slide to the "zero" that you have set. Secondly, if you bring the threading tool close to the work you can set the cross slide crank handle at about the 10:30 o'clock position and set "zero". The compound slide then is used to bring the threading tool to the work and then set "zero" on the compound's dial. The advantage here is that at the end of the thread the cross slide crank handle can be easily snapped back so the threading tool clears the work. This helps a great deal when threading to a shoulder or out of a thread where a thread relief is not permitted.

[@Clough42]

I wanted a smooth surface, and I have a resin printer, so it was a good match. I've not messed with vapor smoothing, but that's my impression: it's hard to control dimensionally. I wonder what would happen to the raised text if I got enough vapor smoothing to erase the layer lines.

Once it is finished, you could 3D print some plugs for the mounting bolt holes that match the contour of the top. You could include a small (1mm) horizontal hole just above the lowest point of the contour on each plug so you can lift them out with a paper clip or small Allen wrench.

[@somebodyelse6673]

Making plugs is a great idea. To make this into a real project, you could CNC a mold and do some injection molding in plastic 😁

No scoop out from the bottom of the block? A relatively small hollowing would make shrinkage control much easier for your casting guy., without noticeable loss of rigidity.
