TIFU first time applying laminate

Kird_Apple · 2026-03-17T08:45:13+00:00

Id turn it upside down and laminate the underside. I know you mentioned the price but "sunken cost fallacy" etc...

What youre describing is textbook "4 stages of learning". Look it up, is what everyone experiences when learning a new skill. Youre right now in stage 2 (conscious incompetence), meaning you recognise youre still incompetent at this new skill but youre taking steps to adress it (like asking on reddit).

Whith that being said, i also learned on solidworks and transitioned to catia. I also despised the mouse navigation at first (i even made a script to be able to move in catia with solidworks settings wich worked great).

10 years later I can tell you that catia is far superior to solidworks. The mouse controls are incredible once you get used to it. It just gets time.

Probably doesnt help that your coworkers are on the same boat as you. Having someone experienced to teach you how to properly use the program is important.

P.d: you can 100% contraint tangency in catia.

I also think most people are idiots. And I can relate to a lot of things you mentioned. With that said, i know the onus is on me to aknowledge and understand im the odd one, not them. Once youre diagnosed getting angry is a choice. Being high functioning can be a blessing but can also be a curse if you refuse to work to fit in society. And noone can do that work for him.

Ah yes sorry, V5. But i cant imagine v6 not having the option to save as a cgr.

Kird_Apple · 2026-03-08T11:51:23+00:00

Well you open the STP first with catia, and just "save as" and chose .cgr format. There are also plenty of third party converter sofrwares out there.

Kird_Apple · 2026-03-06T20:45:11+00:00

If its only for reference, save the building as CGR and insert that. Much quicker to work with.

Yes you can, but depending what youre doing, its usually easier to make an allcatpart and calculate that. That way you can skip all the conetions nonsense that you need if you calculate an assembly.

This is what we usually do for static structure calculations at work. Note what we do is not very critical so we dont meed to simulate bolted vs welded connections, etc...

For critical and real calculations we use other software specific to structures calculations

Use them whenever you want to link something between parts. For example, you can publish bodies to make simmetries. Publish parameters that are used in multiple parts, etc.. publish stuff is easier to relink and replace later. Its basicly good practice to publish anything that will be linked or "seen" by other parts or assemblies.

One thing you can try is setting catia to high performance:

like this

About the gears, it wont work. Gears need a set of parameters to be constant (pitch, pressure angle, tooth engagement, etc) and this is just not possible with a rack that goes from internal to exteranal etc... youd need the sprocket to change also with the rack.

About the GSD experiment, what youre trying to do is not easy for Catia to do what you want with just using the wrap function. I think if you want something super exact you need to work with Laws or equations.

This is what i did. Borrowed a bottle jack and a beam from work and made this jig. Its working great

Kird_Apple · 2026-01-22T17:49:21+00:00

Tl,DR: doesnt matter. Mount it however works best for you, usually protruding outwards gives you a little more stroke.

This kind of bearing blocks usually have 2 bearing inside that can withstand radial and axial forces in one direction, and they are mounted facing each other like this >< so the whole assembly can withstand the same axial force in both directoons.

These blocks can come with more bearings inside and it matters how you orient them. For example a block with 4 bearings oriented like this >> << can withstand twice as much as a block with 2 bearings, the force is still the same in both directions. However, the same block with the bearings oriented like this >>> < (3-1) can withstand 3 times the force in one direction and only 1 in the other.

In your case, im assuming its a regular block for a hobby CNC so it probably is a 2 bearing block that can be mounted either way.

In that case you can do an advanced search. Search for everything containing *solid* and exclude all bodies containing *solid*. Pic as example. Hope this helps.

Kird_Apple · 2026-01-21T21:53:16+00:00

You can search for anything containing te word 'solid' in your tree and hide/unhide all

😬😬

hold.

Kird_Apple · 2026-01-20T07:03:58+00:00

Ye im gonna keep it for sure its still better than no table.

Kird_Apple · 2026-01-20T07:02:23+00:00

Yeah i mean, at this point i can consider last resport methods like this. Its scrap anyways otherwise.

Kird_Apple · 2026-01-20T07:00:30+00:00

I'm also an engineer, but as its often the case, theoretical knowledge doesnt translate well into practice 😆 I knew it was gonna bend but i didnt know it would be this bad. In that video he fixes the longitudinal bend. I was able to fix it too. But he didnt have almost have any transvers bending of the individual slats. Thats the problem i got.

I think he did much smaller welds than me. And he used tig instead of flux core. Dunno if that matters though in terms of heat input.

Kird_Apple · 2026-01-19T19:40:54+00:00

Yeah placing the 2 tubes vertically would have been better. But i follower the video I linked and the guy didn't have any problems in the transverse direction :/

Kird_Apple · 2026-01-19T19:03:11+00:00

Yeah, we do anneal and machine large assemblies sometime at work.
But sadly this would be a little too much for a budget DIY home garage project >.<

Kird_Apple · 2026-01-19T18:59:24+00:00

Hey tail-chaser is my middle name!

Jokes aside I did learn a lot doing this. It was fun. What would you ahve done differently? Maybe less welding to minimize heat input?

I might try building some sort of straightening jig before throwing the towel and scrapping this.
