Making a BT50 Tool Holder for SIP Jig Borer Tooling! | Shop Made Tools

Some serious metal removal to transform this scrap piece of material into a shop made BT50 tool holder for our SIP jig borer tooling! In this video we are making a custom BT50 tool holder to suit all of our bigger SIP hydroptic jig borer tooling but mainly so we can use our Wohlhaupter boring and facing head which has a SIP jig borer arbor. The SIP machines have a very unique spindle and all of the jig borer tools have a matching arbour and drive collet to suit it, but that means we can’t use any of the SIP tools in our conventional milling machines…until now! In this video we show the step-by-step process of turning a scrap piece of 4140 round bar into a new BT50 adapter. First, we setup the angle of the lathe compound to match a standard BT50 arbour before rough machining the OD of the round bar. We then drill and tap a hole to suit the drawer bar bolt of the mill before machining the BT50 taper. We then have to setup the angle of the lathe compound to suit the jig borer tooling before machining the taper on the other end of our material and then counter boring that to suit the collar on the jig borer tooling. Next, we use the milling machine to mill out the square for the drive in the tooling and mill out slots for the drive dogs to suit the spindle before finishing off turning the OD to size between centres in the lathe. We test the new shop made BT50 tool holder with our Wohlhaupter UPA-5 SIP boring and facing head before installing it on our BT50 Zayer 3500 bed-style milling machine!

Love how Karen keeps the audio from the real time shot but switches the video to the sped up shot so it keeps the audio from rising in pitch. Little details like that make this channel absolute amazing production. How do people still watch cable television with stuff like this available?

[scruffy]

Thank you to the gentlemen who set Curtis up with all the nice tooling and cabinets
Very nice score Curtis.

[alewis]

When you're not line boring, making new hydraulic cylinders and taking on customer odd jobs, you're rebuilding a crane from top to bottom and making custom shop tools. That goes beyond mastery, and shows real ownership of your profession.
Thanks for the video and have a great weekend.

[timmillikan]

The fact that both local and international viewers are taking time to look out for tooling for you, is testament to your craftsmanship and quality of work.
Both you and Karen should be very proud of the content you produce.
Great video as always.

[erneststevenson]

To us laymen viewers this was a very complex bit of turning and fitting. You are an artist. I like how you keep your work area clear and clean of swarf at the end of each work day. Thanks for the time it takes Karen to create each posting. She's a gem.

I love how he starts with an image in his head, and is able to turn that image into a perfect tool. No blue prints, no computer, just a man, a machine and pure skill. I love watching these video's where he manufactures something out of nothing and gets it perfect. Brilliant, bloody brilliant! Keep 'em coming Kurtis, These video's are the highlights of my Thursday evenings. (Crazy Canuck)

No drawings, no plans, "I just know what I want at the end of it." Curtis, you're not a machinist, you're an artist! Can't wait to see the finished product! 🙂

[theboldcraftsman]

Dude don't diminish your talent. You are both the theorist and the practitioner. All your designs are in your head in great detail. You are an extremely intelligent and talented guy; it feeds our souls just to watch you. Thank you.

[mlsargent]

I'm an automotive mechanic, and have been for many years. I'm more than pretty good at what I do, but to see the knowledge and skill you have to do a job like this, is just amazing to me! It's a pleasure to watch you use your skills. I find the precision very relaxing!

[czh]

That angle trick was MAGIC! Thanks, saved me some head scratching!!

Kurtis
This is an incredibly intricate job which you made look easy. As a 70 year old applied Australian mathematician who has worked in defence contexts I have been exposed to machinists and mate - you are friggin up there! I know that when JPL wants stuff machined it is like a PhD thesis. I am sitting re-egineering the geometry of what you do works (and it does) and you just do it like a magician. There is Japenese guy Airbus used for a critical part and the final dimensions he did on a lathe by sound ie frequency analysis. There is a YouTube video on it. I did a Fourier analysis at a theoretical level of what type of frequencies he was picking up as I didn’t believe they were within normal human frequency response for the resolution he needed but they were. Amazing. Mate when that Yorkshire welderfabber Baz rates you, you have made it believe me. You know that if I am up your way it will be a canathon of epic proportions!

The merch at the end reminded me - My son recently presented me with a CEE T-shirt for father's day. I put it on and said to him "now I'm dressed for success"! The look on his face was priceless. Speaking of priceless, that would be one way to describe your efforts today. As always, thank you K, K and H 👍

[HrleyBoy]

It is wonderful to see someone working who actually has a clue, I love to see you thriving and improving the business too.

[MrJoey]

I'm a machinist of over 20 years. Curtis's understanding of feeds and speeds is staggering. He simply can 'feel' it. The efficiency is amazing!!

[hot_wheelz]

Seriously mate, to be able to produce something like that without so much as a sketch, you aren't just a dang good machinist Kurtis, you've got the mind's eye of an artist.

[covrtdesign]

Easily one of my favorite videos so far. I have barely been around lathes and couldn't quite figure out how to get that taper. Really didn't think it was that easy.
Love watching you make shop tools!

[felixthecleaner]

wow - you not only repair massive earth moving machines but you fabricate parts and you're also a tool maker too which is a special art all in itself. There aren't many people good enough to make shop working tools but you handled it like a Pro - we were already well impressed with your knowledge of all things engineering but you have talents to spare - awesome work Curtis - and as always brilliant filming and editing too from Karen.

Homie looks ace in his new Hi-Viz!

[brerobsym]

Fixing customers' issues, repairing a crane, making tools for your own use, and yet you still take time to spend with the menagerie that hangs around the workshop. Only a little thing, but it shows how life can be lived - we all need to take time out for those little things! Thanks again, and enjoy your weekend...

[ronmeidlinger]

My dad ran SIPS for use. Glad to see Curtis has the best of the best and appreciates that it is not just an extremely accurate machine but also a work of art.
