Just an idea on cutting the 45s and then the 90s. Could you cut a piece that is about double your length (plus blade kerf) at 90, then go back and make a single cut at 45 in the middle? For this example, if your blade was .1" and you wanted your pieces to be 21.875" on the long end, your original cut piece would be 42.64". More math up front, but less cuts and less wasted material.
Hey Jim, I had my knee done several years ago myself... Took a good year before most of the pain was gone and it was as close to normal as one would expect... Hang in there it will get better...
Thanks, I'm making some 90 degree brackets out of 3" x 3" x ³/¹⁶" angle with a length of 23¹/²" and they absolutely have to be 90* when done. It's been a while since I have made these and your video just reminded me of a few things I fought with last time... Have a great weekend.
Great video and I like how you nailed those 90s. I can usually get them close to square by tacking both the flat sides, then welding them, then the outside corner, and the inside fillet last.
This. I don't like to play around with guessing how much the work is going to move. I do this same thing and it helps me avoid movement in most cases. Only other thing I would add is to weld the joint on the face from inside to outside so that it pulls more in the outward direction which usually isn't much of anything.
Glad to hear things went well with your knee, Jimbo! My Wife had both knees replaced at the same time on December 12th. She is doing amazing as well. Regards, Brian (Rattletrap2)
I had both hips replaced in 2018 and the only thing I remembered was how bad I wanted to get back in the shop. Hang in there, you won't regret getting the replacement. Regarding the 90 degree...I had the same issue and use the same method you suggested. One thing that I found was that the fillet weld was the culprit for pulling the legs together. Leaving the fillet weld out resulted in a perfect 90 every time. Only problem with this method was that some prints called for 100%; and the is where your method works great!
I’ve started cutting the 45° then truing up the other end. If I remember my geometry, it’s probably best to mark each 45° cut so when turned into a 90 it’s a perfect fit because the angles are complimentary. Sometimes we don’t always get a perfect 45°
I enjoy every one of your builds and projects! Like you I discovered that is better to drill square bars in a mill with some compression in the vise. Those bars are not perfectly square and if you don't put pressure on the sides the exit hole in the bottom will not be centered.
Would your theory hold true if you were making a square frame or rectangular frame? I have never heard of opening up the angle a bit before welding out. Especially if you have a fixture table? Thanks Jimbo.
Excuse me, I have an inquiry about the band saw, do you recommend it? What is the highest thickness it can cut? And what is the best quality that you recommend to me!! And how many watts! Thank you
Leaving it fixtured until it's cool takes a good bit of time. When we have several to make, that may be an issue. Or maybe not...I guess you could have several clamped all over the table top, presuming you had a bunch of clamps and nothing else to make for a while?
Order of operation and direction of weld goes a long way toward keeping things flat and square: Outside first, then sides (welding from inside to outside) and inside fillet last. Jason @FireballTool made this great 3 minute video on the topic ua-cam.com/video/lL98oE2NaQg/v-deo.html Hope this helps!
Rumor has it Jimbo fabricated his own knee replacement. Welcome back buddy, good to see you up and about.
Good to see you back Jimbo!!!

Glad to hear that you are doing better after your surgery. Thanks for sharing this video.
Great to see you back, Health is your wealth remember 👍keep the videos coming Jimbo
Glad to hear you're on the mend. Good tips.
Hang in there! Recovery takes a while, but it does get better!

Glad you're back on your feet and in the shop!
Best wishes for a speedy recovery, from Germany.

Just had my knee replaced on monday. Glad to see you back in the shop as I’m going crazy.
Take it easy buddy and rest up. Look forward to more projects.
Weld On. Fab On. Keep making. God bless.
Glad to see you're getting back at it.

That’s actually a great idea
As always great job! I've had both my knee's replaced and no your pain!! Get well soon!
Get better! Good video! Thanks for sharing! 👌👍
Great video as all ways all ways learn something new👍great to see you back aswell hope your knees doing ok don’t over do it.
Good job like olvays, grittings from Poland.

I usually set up a material stop and drill the 1st hole on every pc then repeat with new stop location
Nice job
Apesar de não entender tudo o que diz, compreendo perfeitamente o que faz. Parabéns!
Great video, Remember to grease them new knees Jimbo 👍

Good morning sir have a great day greetings
Would your theory hold true if you were making a square frame or rectangular frame? I have never heard of opening up the angle a bit before welding out. Especially if you have a fixture table? Thanks Jimbo.
Speedy recovery Jimbo 👍👍👍rest rest and more rest and try Apple cider vinegar for quicker healing of your surgery
What's the purpose of the fixture table if you have to account for distortion? Use the pins and clamps to hold it true. Can weld 3 sides while clamped
Thanks
Excuse me, I have an inquiry about the band saw, do you recommend it? What is the highest thickness it can cut? And what is the best quality that you recommend to me!! And how many watts! Thank you
Good to see you again busy in the shop. Is there a rule of thumb how much you its closing up eg 1/16 at every 10 inch?
Its a gamble
One minute 45 seconds in and you already have four commercials! I’ll go watch fingernails vs. chalkboards to go relax now 😂
Can you keep it clamped for all the welds to keep it square?
get well soon
Hope you well good sir 🙏 👍
Hi my name is ismael my question is how much you charge an hour for watt you do fabrication and welding
Hey Jimbo please Share welding parameters,voltage,amperage etc?thanks
What chamfer bit do you use?
If you fixture inside the fillet and don't pull the welldment out until it's cool, it'll stay square as well.
Yep. I thought the same. Make the best use of your fixture table, by doing complete fixturing
Leaving it fixtured until it's cool takes a good bit of time. When we have several to make, that may be an issue. Or maybe not...I guess you could have several clamped all over the table top, presuming you had a bunch of clamps and nothing else to make for a while?
Could have just set up a stop for drill placement
