Built a few similar to these with just some 1/2" plate. Turned some shafts, pressed on the bearings and welded the shafts to the plate. Absolute life saver! I move my bridgeport around the garage with 2 fingers!
One suggestion I would make would be 'soften' the corners and ends of the channel a little, the lower corners in particular appear to be a bit bitey, otherwise an interesting and well conducted job.
Nice clear video and great result. I enjoyed watching your build. You'll be happy with those for years to come. I'm quite far along with my own set coincidentally. I'm using some rectangular section which is not as dimensionally consistent as the channel iron you have, but so far it's been workable. I found some cheap Exacto wheels locally, read plastic wheel with 2x 6204 bearings inside. I'm told good for 400kg per wheel (about 880lb). I'm making two types, the follower type (there are two), and one leader type with 4 wheels outside the platform and a rotating pad. The follower type has two wheel inside the section. I also want to easily re-arrange my machines wheneverneeded. After this a toe jack project ... thanks, glad I could see your build.
Yeah that was a thought, but didn't get to it. Was thinking about a ball and socket joint on top, so a machine could rotate, and then a handle to attach to the front axle. Something to think about.... ----Aaron
I was disappointed by the lack of your usual intro, Years ago I built some skates that failed. But I was using them to move a rail road box car and there was unexpected lateral movement that shattered the bearings. My bearings were undersized for the job when combined with lateral movement they were destined to fail. I do like the project and look forward to seeing their use. Again you built an interesting and useful project. Thank you Shalom
That would be a great addition. I made more skates to move my new lathe and drilled and tapped the top of all the skates for 1/2-13. That allowed me to bolt the skates to the bottom of the lathe so they wouldn't wander away on me. Plywood is a great gripper between metal surfaces.
Thanks for the video! BTW you can probably use 10X less lube on the small drill bits; all that matters is the film on the tip and sides. The rest just spatters and makes a mess.
taurus dragon thanks I’m working on all three. And thanks for sharing your twitter handle- sometimes hard to connect who’s who between social media platforms.
Just saw this, but I made some skates similar to these, but longer. I will caution you against using 4 of them, it's easy for one to slip out if the floor is uneven. Best to use either 3 or 2 longer ones like I use. See this post on PM. www.practicalmachinist.com/vb/general/mini-pivot-machine-skates-design-adopted-robbies-machine-service-269080/ Been almost a year since you posted this video, I'd be curious how 4 are working out for you.

Very nice skates, it's good to see another Phoenix machinist/youtuber
And the "sunny in philly" theme reeled me right in! 😀
Andrew Probst haha yeah I have watched the entire series at least 15 times so this was a natural fit for me 😀
Excellent. Gotta make some now.
Nice job, now if I only had a concrete floor in the Tin Barn. :-)

Nicely done. And I like the video style.
Nice job 👍🏻

Thanks for checking it out. Seems like you’ve got a good handle on the various design needs that might help you.
Solid!
I've been following the IG post. Now watching the video. Great stuff, keep it up!
Andrew Probst thanks Andrew! I’ll be adding more as often as I can.
Hi Aaron, I will be making me a set very soon ! Thanks, David A. Bayer
pretty cool
Nice Job!
Thanks Herb!
Get you a set of gauge blocks. Would make grove placement much easier and faster.
Good job! Subed! Ever think about adding a swivel and long handle to the front skate so you can pull and turn the machine?

Amazing
how much weight would these hold up?

do the bearings leave any marks on the concrete ? i mean do they "sink" a bit ?
Is the form tool you used for the retaining rings a modified parting tool?
what size bearings were these and the load they can handle? i was thinking of using a 6204 bearing which with just 4 per skate should handle 4k lbs.
Dear colleague hello can you give me the link ..for ,ebay, to buy these wonderful cheap bearings thank you
add some 1/4 tall pins on top and put a piece of 1/2 plywood on pins , it will be much easier to keep skates under machines
That would be a great addition. I made more skates to move my new lathe and drilled and tapped the top of all the skates for 1/2-13. That allowed me to bolt the skates to the bottom of the lathe so they wouldn't wander away on me. Plywood is a great gripper between metal surfaces.
have you thought about putting a swivel on the top for making turns ?
I did think of that and just didn't get to it. Would certainly make them better, wouldn't it?
@@AlwaysSunnyintheShop yes it would
Great video. Are you happy with the new layout?
Patrick Pirtle so far so good! Have to reorganize tools in all the boxes since I’ve put it off forever.
Do you prefer anchorlube over regular cutting oil. Thanks
Nothing wrong with Anchor Lube but I prefer cutting oil.
what brand chuck is that?
The lathe chuck is a Jacobs Rubberflex collet chuck, and in the mill it's an Albrecht keyless chuck.
enjoyed....I hit the sub button...
outsidescrewball thanks Chuck! Come on back for more content soon.
I liked the song

That long drill was ground uneven.
first bump bearing shell will crack and fall apart
I've used them several times and bumped them around under load and no failures. Hopefully my good luck continues.
Sir, please upload this design of load bearing and others.
This is very useful to us please

Hi, how do you measure weight it can hold?
I don’t really have a way to do it. I’m sure an engineer could calculate it, but I don’t have that skill.
I see, no problem. thank you 😁👍🏼

Thanks for the video!

you should have a barrier between you and the press, cheaper than a thunk to the head

what is that attachment on the lathe chuck called I have never seen one like this before
The collet chuck? It is a Jacobs Rubberflex chuck.
Nice lighting, sound and camera work! Well done!! (I'm @tigwelder on Instagram).
