Homemade circle jig for plasma oxy cutter invention tool

Homemade circle jig for plasma oxy cutter invention tool
I decided to build me a homemade tool invention which is a quick circle jig for my Powermax45 plasma and oxy cutter. I am cutting out some lids for some small BBQ grills as a test. The circle jig invention tool works great when doing lots of cuts as it holds the size once the nuts is tightened up. This invention seems to do the proper job and will be added to my tool box of homemade tools The Circle Jig tool could also work with a oxy cutting torch with minimal modification. This invention / tool is something to add to my Plasma Cutter tips and tricks. The circle jig tool can be made for under $14.
$5 Magnet'
$3 All Thread 1/2"
$4 Hex nuts 3pc
$1 Bolt, Washer and Nut
Have fun and be safe.
I could not find the exact model of magnet but here are some similar ones that could work.

Here is a quick video I did today on a circle jig. I always wanted to build one and decided to attempt a simple adjustable jig. Total price in parts under $14.

Donde compro el imán ? Where did u get the magnet

[@cutweldngrind]

@@horaciosalinas8145 I got it at Harborfrieght a few months ago. I am not sure how strong it is but might be rated around 30 to 50lb.

[@rikcastillo7605]

Great guide. I'm gonna use your version. I'm cutting 16 dia x 1/4 circle plates for a smoker pit. Then on to 22 dia. Thanks for posting

[@robertlaw8510]

Thank you. You have made a very good circle jig. When the weather gets a bit warmer here I'm going to make one for myself. It looks to be the easiest circle jig to make that doesn't leave a hole.

[@PRR5406]

This is the best home built circle device I've seen thus far.

[@cutweldngrind]

This has worked great for me and there is so many designs I have seen over the years. I actually used the circles I cut out for a stand for my Wilton Vise last week or so.

[@jeffb5463]

Necessity is mother of invention! Excellent!

[@cutweldngrind]

It was a fun project and I have used it several times. Thanks for the comment.

[@Digitonic1]

Thats amazing!! Jorge. Well done!! You da man!!

[@cetate93]

That's sick, thanks for filming this.

[@cutweldngrind]

Thanks, Tool does come in handy and used a few times already.

[@virgiltoepfer7087]

You did awesome. To help line up your magnet mark center line on your plate then what ever the diameter the magnet is draw a circle to help set it in place. Nice job on video!

[@cutweldngrind]

Awesome tip. We learn stuff every day so I appreciate the ideas and comments. I'm always building stuff so hopefully I can bring more videos this year.

[@mattcrowell7945]

Nice design!.thanks for sharing your idea

[@cutweldngrind]

Thanks for liking. This was a quick design and could do some changes on version 2. I need a set screw or 2 to hold the torch in place and centered.

[@StephenOgle]

Great job and well presented. Thanks for sharing.

[@cutweldngrind]

Thanks. I think the setup worked decent and just needs a little modification to remove slack where torch attaches. Thanks for watching.

[@axcreates_official]

Great idea! Well done. 👍

[@cutweldngrind]

Thank you sir.

[@CruiserMac]

Very ingenious, works great !

[@cutweldngrind]

Thanks. Good thing the weather has been nice these past few days 80F / 26.6 C.

Awsome. Thanx man

[@cutweldngrind]

Thanks.

[@ke6bnl]

Ordered the magnet going to build one

[@BigLou956]

Wow, that's awesome bro...👍😎👍

[@cutweldngrind]

It makes cutting circles faster especially when cutting several the same size. I ran out of consumables for the plasma cutter so only made these for the 13" bbq grill to come.

[@fxpestoperator5527]

That is Awesome Brother!!!!!!!!!!!!!

[@cutweldngrind]

Thanks.

[@JsCrazyCutzLLC]

That's pretty slick😎👍

[@cutweldngrind]

Thanks. It's a quick setup I threw together to get some material cut. It's not 100% accurate as I need to apply some adjustments screws to remove the slack on pipe holding torch.

[@hubertrobinson8825]

Awesome is all I can say

[@cutweldngrind]

Thanks. Sometime we just need to be a little creative because some kits are very expensive. I have seen some circle cutter on ebay starting at $50 but this was cheaper lol.

[@donsmith9081]

The butted coupling must be like a jam nut. Nice design, Thanks!

[@cutweldngrind]

Thanks for the input. I actually made this as a quick project but it could use some small upgrades or adjustments. Thanks again

[@chamanqureshi9216]

Good work

[@cutweldngrind]

Thanks. I still use this jig and never actually modified it like I had planned.

[@shaunoneill3727]

Very clever

[@cutweldngrind]

It works great for my application and could use some tweaking for more accurate results. I would probably apply some bolts to apply pressure to plasma cutter torch so it won't wobble much.

[@Paulman50]

That's brilliant. I'll have to knock one of those up for myself. I haven't tried my new plasma cutter yet.

[@cutweldngrind]

What plasma cutter did you get? I got some consumables for my powermax45 ( China clones) and they lasted a whopping 8 inchs or so each. Ebay had them for half the price so bought 3 sets of trash.

[@Paulman50]

@@cutweldngrind it's a Hosung (I think) second hand was $1000 With a 2 year warranty. Apparently can cut 16mm. (5/8)

[@Paulman50]

@@cutweldngrind I was spraying the tip with anti splatter and it made the tips last about 20 to 30 times longer. Could be worth a try.

[@cutweldngrind]

@@Paulman50 I will have to try that on the new consumables I buy. My Powermax45 was $650 used with 0 warranty. I wanted a new one but they are over $2000. Hopefully I can get some more life out of it.

[@bricoletout1]

Great job, now I have found the way to make my own. Just a question… is your welder using gas or not ? Thanks in advance

[@cutweldngrind]

My Mig welders are using flux wire and maybe once I run out I will switch to gas. I actually need a shop to store my welders out of the elements so hope I can build something soon.

[@stihlpancakes661]

Im guessing your tacks are with fluxcore, due to no gas nozzle. Are you able to run a bead without the nozzle? I can see that saving some money in a pinch.

[@Tanhands36]

Nice video. Do you have the magnet marked for center or how are you finding center of circle?

[@cutweldngrind]

I measure from center of pipe to center of nut for my circle cutouts. I might try a diffrent version later since I built this for some cutouts I needed.

[@darylkaufman9142]

What size threaded rod did you use 3/8? Nice set up going to build one!

[@cutweldngrind]

I used 1/2" threaded rod because I had some 1/2" nuts in the tool box that would work for this application. My plasma cutter torch has a ceramic head so I did not put screws to hold torch tight onto pipe I used. So if you want to get better results try adding screws to hold plasma torch in place.

[@gregmccarter2176]

1/2" is exactly what I'm going to use..I have a bunch of it

[@markchamberlin7554]

I made this at work, while watching your video. Everything worked fine till I turned on the plasma cutter. The pipe head caught some slag and the magnet moved off center. So question what is the magnets strength? I'm using a 95lbs magnet.

[@cutweldngrind]

I think my magnet is also rated at 95lbs. I haven't had issues with my magnet moving and have done 6 circle cutouts only. I haven't worked on projects after getting sick but might use it again with the new plasma cutter that I will give away.

[@markchamberlin7554]

@@cutweldngrind i upgraded my all thread to 1/2, also a bigger magnet but with the same amount lbs rating. One last thing and perhaps I didn't catch it during the video, I raised the cup off the table and now only my plasma head touches the metal. everything works great. Thank you.

[@kehindeoluwatosinchanges4605]

Which welder are you using? Flux core (without gas)?

[@cutweldngrind]

I usually use Flux wire on the Titanium MiG 140 from Harbor Freight and my Hobart Champion Elite arc welder. I had planned to buy a tank for the MiG but I really need a shop to store all my tools and projects.

[@ceylonreports]

👍♥️

[@user-Colhchim]

Толково, только вот колёсика не хватает.

[@jessndam06]

Where did you buy that steel sheet?

[@cutweldngrind]

I buy all the new material at Laredo Discount Metals and have it delivered as it's around 90 miles round trip.

[@nicolec7290]

That is the same thing I did.

[@cutweldngrind]

I wish you had a video so I could check it out. Check out my Prime weld plasma cutter video as I am working on more test and a give away of it hopefully soon.

[@rogertaylor8615]

Is that a drag tip or pilot arc

[@cutweldngrind]

The powermax45 is a pilot arc plasma cutter. The shield on it are made for drag cutting from what I was told years ago. I also have shields for gouging which I don't recall if I ever tried it. I haven't really done much in the past 3 months with any or my cutters.

[@rogertaylor8615]

I was asking because I wondered how high it was off of the metal or if it was just dragging on the metal

[@larrylingle7493]

Where did you buy the magnet?

[@cutweldngrind]

I get the magnets on Ebay, Harbor Freight or Ace Hardware. I think this magnet was rated at 90lbs or so which seems to be a good rating to hold it in place.

[@pedroquintin8864]

Need lovely 😍💋 💝💖❤️

[@toddpfister280]

No your supposed to go to a welding shop and spend 300 dollars what are doing you aren't listening to the system

[@cutweldngrind]

My local shop will probably charge and extra 20% lol. I can but a 1x1 square tubing by 3/16 wall thickness from the city and even pay $30 delivery and still save money from my town welding supplier.

[@chimachristian6888]

Good work
