Superb ingenious solution to an otherwise fiddly time consuming job. Love your video’s, no excess waffle, to the point and get on with the job in hand. Awesome, thanks for your time and effort making them!! Regards, Simon.
It's nice watching a true professional. There is a difference in your videos from others out there. Yours not only show how to get it done but also doing it in a timely matter. That’s the difference of being a pro or not. Low mistakes and low time makes a true pro.
Besides being a true pro, your teaching technique is not too shabby either. Experience is the best teacher. You learn from mistakes and just finding better ways from existing knowledge.
That's great stuff Joe, really! I especially appreciate how you pointedly aim to help out us small shops, when you clearly don't need to. You are to be commended sir; Thank you!
Great insight into what goes into producing something that first appears very basic. Makes you realise there is a lot of preparation which has a cost of it's own.
Nice work as usual. Good to see the talk-through of your thought process. Apparently simple solutions to tricky problems still take a bit of thinking to get to! Thanks
Great video, can’t believe the negative comments!! I’m not a professional machinist but find all your videos well made and you describe things really well, I always learn something new from watching, I have looked for some videos from the guys who put up the negative comments but don’t see many! Real surprise!! Please continue with the great work👍👍
Thanks. My moves are usually very calculated for solid reasons. The guys that bash videos like this are from the shops I probably wouldn't want to get parts from. Its also amusing that all the 'Experts' channels are usually music or video game heavy.
Thanks for taking the time to make these awesome videos, Joe! I'm a first year tool and die apprentice in Ohio and my journeyman pointed me to your channel. It has been really helpful to see your in depth explanations to machining processes and theories.
Thanks for sharing your knowledge! Could you please make a video on how you price jobs, both for CNC and manual work? With all the time spent making fixtures for this job, I don't know how I could price it to make money and still be economical for the customer.
Thanks Joe! I was wondering how you were going to trim them to consistent length - then realized 'how' when I saw the second fixture. Great example and demo, thanks again, Joe
Another creative solution to a seemingly simple problem Like Your use of specific Jigs to hold these parts. Could well be applied by us in most Manual Machining projects. Great ideas here for similar jobs. Thanks as always Cap'n for showing and sharing ATB aRM
Nicely worked through Joe. Hope you have good storage for your fixtures -- you know the week after you ditch them the client will be back on for a follow up ;-) Thanks for sharing. Mat
I love fixture work for production. We always mad 2 identical fixtures so we could load one while the other was running. But, that was for 1000's of parts per order. Man, I'd give my right pinky and ring finger for a Bridgeport with a prototrak controller on it. I know there's better heads out there, but you know. Nostalgia.
Another amazing video. Extremely informative as always. Fixturing is an Art and Science in and of itself and you seem to really have a knack, Thanks for sharing your knowledge.
This is a good example to all those (and you seem to attract a reasonable number of them Joe) that think CNC machinists are not real machinists. I takes a real machinist to plan out a job so non machinist button pushers can take over, CNC or otherwise. Delusional, nostalgic or just trolling, I believe these people can't or won't distinguish the two scenarios CNC machines can be employed. Banks of machines lined up making thousands of the same parts run by semi skilled operator and managed by a skilled tool setter. Then there is the job shop constantly changing jobs with limited or singular production frequently with features that are difficult or impossible by manual means. These machines are usually completely run by skilled machinists and any machinist with real skin in the game will acknowledge this even if the skill sets are different.
That was impressive too (came here from the grip stock video). Might I say, I read some of the comments further down, they were really not nice and certainly not deserved. You handled them with as much skill as you create your videos and dealt with your critics beautifully. I will remember that as much as I will try to remember the video.
Thanks for the comment. Being diplomatic isn't always easy, but sometimes it can open eyes better than a blast. Everyone is entitled to their opinion. When it gets personal, thats when I end it.
Joe Pieczynski I just hope I can handle it so well if I cop that sort of comment. So far I have been lucky, having a very small channel probably helps too.
I've been cutting alot of delron for DRS lately, holding +-.0005 on most of their parts. I always us my reminder saying, "very lightly clamp your part, if you think your vise jaws are to tight loosen them a bit", that delron cuts like butter and will hold under minimal pressure. I will be using your drill, band saw, and softjaw setup for a similar part, thanks for the video! I have all sorts of delron setups i like using!
Joe Pieczynski Yeah don't start with sheet, quote based on using large oversized stock and mill symmetrical to size. I have done a lot of Delrin machining. I have ground Delrin to ten thousandths of an inch. It's very versatile and a great option.
T.J. Mackiewicz You can also surface grind Delrin. Some thin double sided tape and an open dressed 32 or 46 wheel and light passes. I've ground it to within .0002" tolerance.
Absolutely ingenious! It was truly refreshing to see somebody go through the effort of creating clever jigs etc., to guarantee a high-quality (and repeatable) end product, where the majority would most likely have taken a quick, cheap and easy way, without further thoughts... After an evaluation period, I have now subscribed to your channel... Would have been stupid not to! Thanks for sharing your considerable knowledge. With cheers from Outback Australia, Rolf
Having spent 37 years as a heavy duty mechanic in a high production dealership clean up time is as valuable as the job its self I see a lot of people using compressed air to blow off their parts where debris goes everywhere I always liked using my compressed air vacuum to control cleanliness inside of engines so why not retrieve chips during machining process and eliminate any additional time cleaning up the machines Time is money unless you like doing it for fun
Great job highlighting fixturing! I am not sure if I would have thought about the drawer slide feature but that saved mount and demount time. The vice like clamp I would think will have future fixturing utility. Itself would be an interesting project to have some video. I would have been inclined to make it from steel for double duty for similar small parts use on a surface grinder. Not a criticism. We called that sort of fixturing "ganged" fixtures. Pallets are a hot topic these days, this is going to give me some food for thought before I build one. As always a well thought out job and a pleasure to watch Joe Pie make a piece-of-cake, lol... Happy Turkey Day to you and yours.
That was great, Joe! Planning ahead every detail of those fixtures so the actual cutting was done quickly and, most important, ensuring the quality of the final product, really shows how professional you and your team are. I worked at a company that made dies for aluminium extrusion, that was 99% of their work and they had the production process very well optimized, wire EDM, big horizontal machining centers and all that stuff, but for the occasional 100 part job, they didn't even had a decent set of parallels. It was a struggle, with every part taken out of the vise 3 or 4 times, chatter, vise jaw lift...The parts came back from the customer more often than not.
Thank you. Rejects and returns are not OK around here. I take the quality of my work very personally as it reflects directly on my ability and skill. I like jobs like this. They make ya think.
That was great Joe. Although not exactly the problem I was having with a project it helped me think out side the box and come up with a solution. Thank you.
Nice work. I am just running a manual Bridgeport mill doing job shop type work and I probably would not quote that job with my setup. Thanks for making the video.
Great work Joe. Delrin is the bane of my life as I'm starting out building dive gear for a living. Easy to cut but an absulute bitch to hold, especially if you're cutting large thin pieces. Every day's a school day though and I'm learning today.
I know my observation is a silly little thing, but I liked on the band-saw how you used the off-cut dog-bone riser as a pusher stick at the end of the cutting operation.
Would you say that the fixtures you made took more time and labor than the parts themselves? And is that time included when you quote the price to make these parts? Just asking..
Joe, before you ever accept the job, do you ever ask if there will be repeat orders, assuming they like your work ? That was a hell of a lot of fixture making time and materials. I have no CNC experiance, but I certainly would not have taken this job on for just 100 parts. You probably spent more time making the fixtures than it took to make the parts. Looked a good job as always though. Well done. Now off topic I know, did you ever get your gun part Anodized ?
That does seem like a lot of fixture time, for 1 order of 100 small parts. Most likely a long time customer and a new part. Joe is probably expecting future orders of that part.
If he does only one run of those, the customer must be ready to pay a pretty heavy setup fee, if there are repeats then, the cost gets amortized as he has more parts done... ;) Aluminum and mostly Delrin aren't cheap...!!!
When I get a job like this, I stand back and think.....I can struggle with 100 parts one at a time and consume a bunch of hours, or spend my time making a fixture I may use again and fly through the parts in the same amount of total time. I usually go with the fixture for part consistency and future profitability. The AR lowers did get anodized and I will show the results. The clear came out a very unique color.
Nice job Joe. i did a job typical. but 5 at a time they were end caps for extruded alu.. 2 setups and i made a fixture to cut them off on the table saw finished. helped pay for the tormach then the haas mini. great job..
Hi Joe, this is where divergent thinking wins the day. An awesome result, but I disagree when you said a few thousand, how about 10,000, now that's what I call super cool.😂😂😂😂😂. Many thanks for sharing you knowledge and skills. Kindest regards. Joe.
Awesome...thanks for sharing.....I would assume that there was more time/cost in the fixtures than the final part....can you share what the price per part was to the client?
Hey man great video, I love a bit of creative fixturing. I am a big fan of the incremental move using a loop too, you can produce some very economical programs from this method. Plus, if you need to make changes you don’t need to go trawling through lines and lines of code. 👍
sweet setup there. im guessing these are for a proof of concept mockup. easier and cheaper to do than build a mold to find a part that wont work. but as long as ya get paid who cares. i enjoy watching and learning.
Just had to make hold downs for a 10' sheet of anodized aluminum plate for my cnc router. I made the hold down blocks out of black delrin and they worked great. I flexed them a bit for the 80 parts I made and they kept their resilance til the end. Keep those drop off's from the band saw, they can come in handy.
+1 I make all sorts of things out of it and haven't been disappointed yet. My only problem is other people want me to make things out of it that just won't work. lol
Joe, do you ever use something like double-sided adhesive tapes to fixture parts; especially where machining forces are low, or drilling, or straight shear, these products allow for kind of "pseudo-dogbone" approach, with a fixture/carrier that carries many parts...we do thousands of tiny parts like this in the PCB industry, where parts are really much ro small to handle idividually, and, in fact, are often delivered on a."sticky tape" baxking, with low peel strength, enabling separation of individual parts quite nicely, and keeping them "organised" in the meantime ;-)
Did the money you spent on the materials to make the fixtures come out to be less than the price quoted to the customer? That seemed like a lot of alloy for a very specific 100 plastic piece job.
Hey Joe, nice video and parts. I have couple questions though. As you stated near the end of the video, you wish you 1,000 of these. Is it worth building fixtures like the kind you have for 100 pieces? Also, the amount of material (Delrin is not cheap) seems to be a lot more waste than just using closer thickness stock. Just my thoughts, enjoyed the vid!
for work like this i wouldve built a small fixture with a boss the same as the pocket and to locate off the two holes for the final operation, used to do stuff like this all the time
That is one very fine fixture... sure proves a point with the technique. Beautiful parts Joe. As the saying goes - ''it's all in the set up''! Wonder how much time went into fixture production. Another fine video. :)
Cool video and appreciate them. Strategy vs quantity is always worth taking a few moment to plan. Last op for only 100 pcs. being made from delrin could also probably just lay a couple gage pins square to and on top of the hard jaws with stop on a pin using a couple 1/8 thin AL straps to set down in the vise between the pins to help support. 2' long pins do maybe18 per shot.
I would have liked to seen the initial operation. I assume the second side required some sort of backing fixture to support the midsection and keep it from flexing away from the cutter.
Nice fixture and job approach. It always pays to plan thoroughly and have a fixture that works as you expect otherwise you spend all day fighting against it. Been there and done that.Just wondering whether you tighten those cap heads in any specific order or to a specific torque setting?
It looks like a lot of time spent on the fixtures relative to the lot size. What was the total time of the job end-to-end with all the figuring and fixturing - setup parts, etc?
Pretty quick! Were the fixures a scratch design/setup or did you already have something close enough to modify or adapt? The end result was pretty slick, I just don't think I could have pulled it off that fast. Hats off.
Hey Joe is there any particular reason the fixture has cap screws with washers on one side and not the other? (Wouldn’t think so but since I’m new to machining I️ figure I️ don’t know what I️ don’t know. Thanks for the awesome channel man!)
I'll wager a guess. The cap screws without washers only have to clamp down on the part, the backstop is built into the base of the fixture. The cap screws with washers have to clamp down and push the part against the backstop. If so, the holes are probably oversized a little and the washers keep the cap heads from centering on the holes and pulling the jaw away from the part. The piece I'm not certain about is the small step where the jaw mates with the base. Seems like it'd interfere with the jaw pushing the part against the backstop. Maybe the dogbone ends extend out enough to compensate.
2 answers here. Washers are used under the front jaw because the holes are a little bigger, and the material is aluminum. I didn't want to imprint the jaw with the screw head and not be able to apply rearward force each time. The little step in the bottom of that jaw is so the front of the jaw tips down during clamping and doesn't raise the center of the part by clamping on the outer most material edge. The clamps are .oo5 taller than the material and pinch .200 into the stock.
As a German, I cringe when I see the use of imperial units. I can not cringe more, so I don't know what to do when I see them mixed with metric units. Mixing them without indicating the units is so mind bending that it's funny! It made my day. To be clear, the video is brilliant!
As a Brit I too cringe at the use of imperial units! I was at school when we went metric so I half my schooling was in one & half in the other system. I swap about but out of habit - imperial for casual "about an inch", & metric for accuracy. I mean who wants to divide 7 & 15/32nds by 3 & 35/64ths? Give me decimals every time!
I don't know if you teach or have in the past but you have a talent for it.
Thank you.
Superb ingenious solution to an otherwise fiddly time consuming job. Love your video’s, no excess waffle, to the point and get on with the job in hand. Awesome, thanks for your time and effort making them!! Regards, Simon.

Very creative, efficient and interesting techniques and jigs. Nice work. Impressed here.
As always, interesting and instructive. Thanks for taking the time and effort to make these videos.
Thanks for taking the time to make these awesome videos, Joe! I'm a first year tool and die apprentice in Ohio and my journeyman pointed me to your channel. It has been really helpful to see your in depth explanations to machining processes and theories.

Fixtures can make or break a job and those look great, fixtures are everything. Nice job!
I wanted to thank you for sharing. It's pretty easy to learn machining but it's not always easy to learn a lot of these techniques of work holding.
Thanks Joe! I was wondering how you were going to trim them to consistent length - then realized 'how' when I saw the second fixture. Great example and demo, thanks again, Joe
Another creative solution to a seemingly simple problem

Machining philosophy applies to manual and CNC. Glad you feel the same way.
Nice video Joe, learn something every time I watch.
My next video is on exceptionally small hole drilling. You'll like that one. Stay tuned.
Nicely worked through Joe. Hope you have good storage for your fixtures -- you know the week after you ditch them the client will be back on for a follow up ;-) Thanks for sharing. Mat
very clever fixtures, the sure sign of a seasoned pro
I like tooling. It was a huge part of my apprenticeship.
Ending with "that's all I got". How humble. Thank you so much for sharing. I know you have lots more and looking forward to it :-)
This bloke's unstoppable!!! Keep 'em coming.
These production job shop tips are super helpful. Thanks, Joe.
I love fixture work for production. We always mad 2 identical fixtures so we could load one while the other was running. But, that was for 1000's of parts per order.

Well put. I agree.
You have a very intelligent approach Joe, big credit to you for sharing, just subscribed.
One of the best channels on youtube, my friend.
Thank you very much. I am enjoying the effort.
No two ways about it Joe- you really have mastered the art!
I love all of your work-holding tips, thanks for all the help you provide
Glad to do it.
i like your thinking, planning and execution.
Thank you. This worked like a charm.
Awesome, Great stuff..... your video (second fixture) gave me the best solution for a gang of small alum. parts I am doing. Thank You JP
Glad it helped!
That was impressive too (came here from the grip stock video). Might I say, I read some of the comments further down, they were really not nice and certainly not deserved. You handled them with as much skill as you create your videos and dealt with your critics beautifully. I will remember that as much as I will try to remember the video.

This is great material, but does have surface tension in sheet form. Single sided operations can be tricky.
Joe Pieczynski Yeah don't start with sheet, quote based on using large oversized stock and mill symmetrical to size. I have done a lot of Delrin machining. I have ground Delrin to ten thousandths of an inch. It's very versatile and a great option.
You haven't cut any delron. It's Delrin
T.J. Mackiewicz You can also surface grind Delrin. Some thin double sided tape and an open dressed 32 or 46 wheel and light passes. I've ground it to within .0002" tolerance.
James G yea ive since switched techniques to double side tape!
Absolutely ingenious! It was truly refreshing to see somebody go through the effort of creating clever jigs etc., to guarantee a high-quality (and repeatable) end product, where the majority would most likely have taken a quick, cheap and easy way, without further thoughts...

I always liked using my compressed air vacuum to control cleanliness inside of engines so why not retrieve chips during machining process and eliminate any additional time cleaning up the machines
Time is money unless you like doing it for fun
As always, a perfect masterclass
The master of the milled/ turned material ,strikes again!!!!
Its good to have knowledge of the material properties to have good results.
I always learn something watching you videos, Joe! Thanks for posting.
Thanks for watching.
27 seconds to finish the part, 35 seconds to admire your work. :-)
I always get a kick our of trying to read the doodles on the whiteboard... You can tell there's nice camaradery in your shop. I love it!

Excellent! Thanks, Joe. Another useful bag of tricks.

I enjoy that part too. Its always better when they perform as intended.
Nice job Joe. i did a job typical. but 5 at a time they were end caps for extruded alu.. 2 setups and i made a fixture to cut them off on the table saw finished. helped pay for the tormach then the haas mini. great job..
I'm about to post a video on something I call flip flop milling. check it out when it posts. I think you'll like it.
Joe, so you made 2 custom fixtures to do that 100 pieces black derlin? It wasn't even mass production?
Hi Joe, this is where divergent thinking wins the day. An awesome result, but I disagree when you said a few thousand, how about 10,000, now that's what I call super cool.😂😂😂😂😂. Many thanks for sharing you knowledge and skills. Kindest regards. Joe.
At 10,000 pieces, that strip would have been 40" long.
That was excellent. Thank you for the thorough walkthrough.
This was a good job. I hope it repeats.
precision and production nice to watch you work Joe
Awesome...thanks for sharing.....I would assume that there was more time/cost in the fixtures than the final part....can you share what the price per part was to the client?
Thanks Chuck.
Really this video blew my mind how simple and efficient it is
Thanks. Its a good approach for smaller parts. The material wasted is more than made up for in time saved.
Thanks Joe
@@joepie221 The material is not "wasted". It's "utilized" to make the job more efficient!
Hey man great video, I love a bit of creative fixturing. I am a big fan of the incremental move using a loop too, you can produce some very economical programs from this method. Plus, if you need to make changes you don’t need to go trawling through lines and lines of code. 👍

Another great video! Thanks for sharing this technique with us.
Great video and great ideas! Thanks!!! It looks like in the final pics(15:46) that the holes are chamfered. If they are, how was that done?
I had a conical c'sink with the angled through hole. I did them by hand before I sawed them off. Took about 5 minutes per strip of 21.
Nice touch! They look perfectly uniform. I figured by hand would be faster, they just looked so perfect, it raised the question. Thanks Joe.
Makes me proud to be Polish . Keep up the great work .
Thank you.
Nice job ,nice fixtures for the job. Thanks for sharing
Another fine Manual or CNC KISS tip.
Thanks Joe.
"No brainer little fixture"...
I will keep this technique in mind for the next time something like this comes up. Thanks!
Just had to make hold downs for a 10' sheet of anodized aluminum
plate for my cnc router. I made the hold down blocks out of black
delrin and they worked great. I flexed them a bit for the 80 parts
I made and they kept their resilance til the end.
Keep those drop off's from the band saw, they can come in handy.
I have a whole box. You never know when they may come in handy.
love working with Delrin and Celcon. I wish everything was as nice as that stuff.
My favorite material. It does have a grain structure though and will warp terribly if not handled right.
+1 I make all sorts of things out of it and haven't been disappointed yet. My only problem is other people want me to make things out of it that just won't work. lol
Joe, do you ever use something like double-sided adhesive tapes to fixture parts; especially where machining forces are low, or drilling, or straight shear, these products allow for kind of "pseudo-dogbone" approach, with a fixture/carrier that carries many parts...we do thousands of tiny parts like this in the PCB industry, where parts are really much ro small to handle idividually, and, in fact, are often delivered on a."sticky tape" baxking, with low peel strength, enabling separation of individual parts quite nicely, and keeping them "organised" in the meantime ;-)
I'm sure this would be the fastest and most accurate way to do this even without the cnc mill.. Thanks Joe, always learning! 😁
I like this kind of stuff. And the fixtures - whew! Looks like it could be a deal breaker if not well planned..
Brilliant insight Joe. Great informative vids. Cheers from the UK 🤘
Easy peasy if your Joe Pie” truly professional, thanks joe more please simply the best.
Watch the micro drilling video coming right up.
Did the money you spent on the materials to make the fixtures come out to be less than the price quoted to the customer? That seemed like a lot of alloy for a very specific 100 plastic piece job.
Hey Joe, nice video and parts. I have couple questions though. As you stated near the end of the video, you wish you 1,000 of these. Is it worth building fixtures like the kind you have for 100 pieces? Also, the amount of material (Delrin is not cheap) seems to be a lot more waste than just using closer thickness stock. Just my thoughts, enjoyed the vid!
for work like this i wouldve built a small fixture with a boss the same as the pocket and to locate off the two holes for the final operation, used to do stuff like this all the time
That is one very fine fixture... sure proves a point with the technique. Beautiful parts Joe.
As the saying goes - ''it's all in the set up''! Wonder how much time went into fixture production.
Another fine video. :)
Half a day on the tooling. Less on the parts.
Cool video and appreciate them. Strategy vs quantity is always worth taking a few moment to plan. Last op for only 100 pcs. being made from delrin could also probably just lay a couple gage pins square to and on top of the hard jaws with stop on a pin using a couple 1/8 thin AL straps to set down in the vise between the pins to help support. 2' long pins do maybe18 per shot.
Nice work Joe, I’d be happy if I could machine the jigs let alone the parts, thanks for posting
Thank you.
Great job holding those small parts and milling the ends ------ thanks for sharing
Great video Joe, thanks for sharing!
Thanks for sharing Joe! great solution mate
Awesome workholding video! I would love to see more!
I would have liked to seen the initial operation. I assume the second side required some sort of backing fixture to support the midsection and keep it from flexing away from the cutter.
Great video well thought holding fixtures the parts turned out PERFECT!
Nice fixture and job approach. It always pays to plan thoroughly and have a fixture that works as you expect otherwise you spend all day fighting against it. Been there and done that.Just wondering whether you tighten those cap heads in any specific order or to a specific torque setting?
He mentioned "repeat jobs", and the more the merrier, if your going to make a group fixture.
Hey Joe, just for the hell of it. Tell us how many fixtures you made & collected over the years. Now, that make a great video. As always, Great Video.
Holy cow, how much time ya got.
Another great technique. Thanks for sharing!
Thanks for watching
Thanks for the tip yesterday on not knocking down the first opp.
Thats very important in getting a part flat.. You're welcome.
We all appreciate the time and effort you put into these videos.
Hi I enjoy your video very much. Just curious that what kind of CNC milling machine you used in the video. Thanks!
Its a Fadal 4020A
It looks like a lot of time spent on the fixtures relative to the lot size. What was the total time of the job end-to-end with all the figuring and fixturing - setup parts, etc?
About 6 1/2 hours total.
Pretty quick! Were the fixures a scratch design/setup or did you already have something close enough to modify or adapt? The end result was pretty slick, I just don't think I could have pulled it off that fast. Hats off.
Very interesting setup joe, thanks.
Awesome work Joe!
Thank you for the comment and your sub. Much appreciated.
Hey Joe is there any particular reason the fixture has cap screws with washers on one side and not the other?
(Wouldn’t think so but since I’m new to machining I️ figure I️ don’t know what I️ don’t know. Thanks for the awesome channel man!)
I'll wager a guess. The cap screws without washers only have to clamp down on the part, the backstop is built into the base of the fixture. The cap screws with washers have to clamp down and push the part against the backstop. If so, the holes are probably oversized a little and the washers keep the cap heads from centering on the holes and pulling the jaw away from the part. The piece I'm not certain about is the small step where the jaw mates with the base. Seems like it'd interfere with the jaw pushing the part against the backstop. Maybe the dogbone ends extend out enough to compensate.
2 answers here. Washers are used under the front jaw because the holes are a little bigger, and the material is aluminum. I didn't want to imprint the jaw with the screw head and not be able to apply rearward force each time. The little step in the bottom of that jaw is so the front of the jaw tips down during clamping and doesn't raise the center of the part by clamping on the outer most material edge. The clamps are .oo5 taller than the material and pinch .200 into the stock.
Very helpful video. Much appreciated!
As a German, I cringe when I see the use of imperial units. I can not cringe more, so I don't know what to do when I see them mixed with metric units. Mixing them without indicating the units is so mind bending that it's funny! It made my day. To be clear, the video is brilliant!
As a Brit I too cringe at the use of imperial units! I was at school when we went metric so I half my schooling was in one & half in the other system. I swap about but out of habit - imperial for casual "about an inch", & metric for accuracy. I mean who wants to divide 7 & 15/32nds by 3 & 35/64ths? Give me decimals every time!
Really slick way to get those done!
Fantastic video, Thanks for taking the time to do the video i will definitely try this method. Keep up the great work.
Thank you.
Awesome fixture engineering.
