bird cooch posted:it's amazing that you pointed this out it actually took me forever to find that bolt but due to the clearances on the backside of the flywheel we weren't able to use any sort of flanged bolt. Without beating a dead horse here, my thinking was to buy the BMW screws and send them out to someone (like the new guy) to do the second op of turning down the flange to the diameter of the eTorx head on the already hardened and to spec fastener. I saw the turning center in your pic there, and, well, that seemed a lot easier than roughing, threading and broaching each one out of bar stock. The final adapter is beautiful. I haven't done anything with EDM, but holey moley, just thinking about having that capability makes my head spin. Super cool thread. bird cooch posted:I am lucky to have some amazing friends who are total instigators and enablers pushing me to make even weirder and crazier cars. Birds of a feather and all that.

It would be a lot easier to chuck up in the lathe and just turn down the shoulders a little bit. I can't remember if there was a solid reason why we didn't do that. bird cooch fucked around with this message at 23:19 on Dec 11, 2020 |

This is real neato. I really like your photos and your writing, and especially the photos of your berner. It is interesting to hear about people swapping the BMW DCT into other cars but I am certainly in favor of it. I specifically chose the DCT for My E90 M3 and four years later I am really happy with my choice.

I should have figured I wasn't charting new territory and had found something that you weren't aware of. If you can't remember why, that's totally fine, but this kind of thing fascinates me- why the m12x1.0 super fine oddball thread on a part you were also cutting the female threads on? Clamping strength? /derail. Please keep the beauty pics of machined and fabricated doodads coming. glyph fucked around with this message at 23:52 on Dec 11, 2020 |

Especially with integration into modern traction control and shift speeds and ramp in ramp out for clamp down forces it's hard to argue with. We will see how well I am able to handle the integration. These cars have a lot of moving parts. She's a babe.  Goof troop is the real comic relief around here.

If I can get time away this weekend I'm going to weld in the fixtures for an 8.8 in the k car. As much for gear selection as for durability. The rotary car will stay stock rear end if I can make an ideal Street ratio workout in that diff.

I've got 2 project threads on the go too so I am well into the entirety of this statement!  I can only dream of achieving anything like your custom iconel and lathe related works on my projects. I'm just bolting various parts together (and welding them) whereas you're actually making the parts yourself before you bolt them together using your own custom fasteners.....

kastein posted:I'm curious what one-off rotary broaching and EDM spline cutting like that costs, as I may need several similar parts done in the near future for a gearbox project I'm working on. So all this stuff was done in batches. The bolts were literally produced by a friend on borrowed machines so the price was beer. He's a mech engineer and wanted to learn how to do it. The quote I got for a run of bolts was really high. Like 20-50$ per with a minimum run of 100. I have had great luck in the past walking into industrial repair machine shops and getting stuff done for beer. Those guys tool up for weird jobs a half dozen times a day. It cost 3-4k in tooling just to make those bolts with free machine access. Special thread micrometers, the very fine thread roller was pretty expensive and the rotary brooch itself. Plus incidentals. I honestly don't know what the EDM costs per run, I generally get that stuff done as part of a package for development of the part. Sometimes that stuff is for free work sometimes that stuff is for a percentage of sales coming forward or a set number of unit sales. Even at that point I usually just trade that in for more work. I'll ask though, give me some rough specifications so I can get you a decent quote.

The other FD is rotary and staying that way. I'm gathering parts to stack a couple motors I just need to do some handicap accessible modifications. Other than that I'm going to throw a all of those fancy little dumb parts I've been hoarding and a few things I picked up in Japan and stuff like that at that car. And just about wrapped up the shop last night.   I need to pop the engine off the transmission and get that ready to machine for a couple dowels this evening. So that should be a good time

I'm going to do the foam board insulation for the ceiling well, as the ceiling . It's got aluminum on the backside so that should really help with lighting. Also I want to note I'm a huge fan of your thread that stuff is a bunch of fun and looks amazing. We essentially got to do over. After all of the work it feels like the tornado did us a solid.

What kind of insulation are you planning to put in? I'm facing a similar issue, want to make sure I'm not missing a product I could use. I haven't found any form board product that was appropriate for direct, uncovered install in an environment that is likely to see flying sparks.

If I were to do it all over again I would install a shop gantry. This weekend or next week I'm going to bolt some angle iron down to the floor so that the wheels track on the lift. you have to spend a lot of time walking around to each side scooting it when you're putting stuff in instead of just grabbing it with one hand. It is a lot nicer than having to do it on the ground. sharkytm posted:Even better: get a forklift. This is the right answer

I know less than zero about this stuff. Are those I beam chain hoists expensive? A little impractical I guess if you're trying to move something in more than one dimension.

The gantry crane itself is about $700 from Harbor Freight: https://www.harborfreight.com/1-ton-telescoping-gantry-crane-41188.html Then you need a hoist or chain fall for around $75: https://www.harborfreight.com/2-ton-chain-hoist-631.html You’ll notice that the gantry has wheels, and that the attachment point for the hoist rolls along the beam, so you can move things around.

I got my Gantry from northern tool for like 400 bucks and then I spent another three or four hundred dollars on the jet roller and the jet one ton chainfall. But I am going to upgrade to an electric winch on the roller here pretty soon because sometimes the chains are just in my way. But for Fab on the lift it is absolutely amazing I can move the entire motor with one hand and it stays at exactly that height forever instead of having to worry about having a hydraulic cylinder holding it up. having it on wheels is great I still need to build a rail system on the floor so that it goes forward and backwards in relation to the lift easy instead of castering. There's no worry about reach for an engine hoist and all of that stuff and the ability to roll it around the shop and pick up transmissions and engines and stuff like that is great.

Neat. I’m guessing at some point overhead hoists can support loads that freestanding gantries can’t? I mean I’m aware that like shipyards have massive gantries but in terms of hone shop practical equipment.

I can just about lift my cars with this one, but if I had it to do all over again I would have done a building gantry, but I don't have room to clear the top of the lift. We had enormous Gantry cranes when I worked at Boeing that could lift entire airplanes and move them around the building. And had another job working automation at electro impact we had huge ones that we used to move heavy machinery and composite laying robots in each building. They are really trick.

Built in overhead beam trolleys with a chain hoist are neat, but require a lot of pre planning with the structure if you want them to have really useful lift capacity, and are limited in that you have to get the work right under the beam. The trolley crane systems that combine a beam trolley that can also move laterally are $$$$$ to $$$$$$+. Really those roll around gantry cranes are the best bang for the buck if you can deal with the limited height, and have room to store it.

The trolley crane systems that combine a beam trolley that can also move laterally are $$$$$ to $$$$$$+. It’s not that bad. Think of a trolley crane in a garage or small shop like a pair of gantry cranes connected by a beam. Neither needs to be powered in that environment, so you just need 3 beams, and four posts, plus the trollies, which will probably be the expensive part. It can be retrofitted, if you have space.

I hit a snag that I normally don't have an issue with. I am unable to buy tooling right now. Like a lot of folks I made do with cheaper tools for a long time and when it comes to grinders and cutters and all of that sort of stuff. when the shop was damaged a lot of that gear was damaged or exposed to the elements for a brief amount of time. I'm sure we all know that even if you clean it up electrical stuff generally has a shortened lifespan after that. My belt grinder died. Okay not a big deal I've had it for 20 years I'll just buy a new one... But you can't find them. you can find the little bitty teeny tiny ones or the harbor freight junk but I guess there's a knife making show or something that's getting people to buy up all of the metalworking equipment? I'm not 100% on exactly what's going on. So I have spent the last week on some sort of horrible scavenger hunt. Or a quest. a quest that sounds even better. instead of orcs and goblins and trolls I am doing battle with old guys who "know what they have" and resellers with 100% markups for used industrial equipment that's older than I am. I've got a list of stuff that would just be nice to have in my home shop so that I don't have to farm out easy machining or spend a ton of time cutting things down by hand when throwing it on the Bridgeport will do the job. Here's an example. *The party enters the Craigslist/facebook marketplace pit of despair* I went to go look at a supposedly Nice condition knee Mill. It is actually in Nice condition surprisingly.  (My dad giving me side eye while I pretend I don't know that the seller is wrong about how easy it's going to be to hook up) it looks like somebody bought a brand new Mill 15 years ago and put it in his garage and never used it It's got good vices and a turn fixture and all sorts of neat stuff but the asking price has been pulled out of thin air so he's going to have to accept a lower offer..... but it's an old man so I have to play a game. we're both going to spend the next two weeks pretending that after not touching it for 15 years he's going to hook up power to it for a test. he also had a pretty nice lathe that he had accidentally knocked over with his forklift (and cracked the bed) that has been sitting there for the same amount of time with the same amount of setup untouched. This is a fairly cheap Taiwanese manufactured Mill. You can buy them brand new from Atrump without the power feeds or vices fixturing etc for 8k. That's really cheap. Same story over and over. It's a grind, it's the holidays. it's the Rona. It's really frustrating. Also my intake manifold and some of my plumbing is hung up shipping somewhere in Narnia because it's the holidays and the rona blah blah blah. Losing inertia is the worst. https://youtu.be/qfNmyxV2Ncw bird cooch fucked around with this message at 18:13 on Dec 24, 2020 |

All I can guess is the popularity of flipping shows / pawn stars etc. Just a constant stream of "best I can do is $7" followed by "it's a genuine pollock we sold for millions" just breaking everyone. Nobody wants to feel like a sucker to the point they'd rather not sell it I think. Dude doesn't even have the mill he bought years ago under power in his own place?
