You're assuming Russians will just keep on as they are as if nothing happens. But it's not guaranteed. What if they repurpose a plant or two to making the cheapest tanks possible, let's say T-34? What if they call a general draft?
A T-34 would be next to unless in Ukraine, and would just be a death sentence, a T-34 probably isn't even worth fielding against the more modern armour and ATGM's that are in Ukraine.
Not to mention that Russia likely doesn't have any tank groups trained on the T-34 so they would need to spend time doing that as well.
If Russia calls a general draft they are beyond desperate, their actual contract army is already doing incredibly poorly in Ukraine, called up conscripts would do even worse.
Its worth keeping in mind that Russia still needs to defend the rest of its territory whilst invading Ukraine, they are incredibly paranoid about NATO and if Finland/Sweden join NATO they will need to deploy more troops to that border to try look like a real super power again.
Russia had a "Made in Russia" program for the military. But apparently bribes let many side step the rules and post proud "Made in Russia" announcements in the press, while basically relabeling imported parts. Even more amusing is a fair number of those parts come from the Ukraine.
More factories isn't going to help, and these days it's hard to steer, power, target an enemy, or communicate without chips, which Russia is running very short of. Intel, AMD, and even Russia designed CPUs (Elbrus) are hard to come by, TSMC (and other foreign fabs) are honoring the sanctions.
Apparently even the basics like steel are getting hard to come by.

aren't they a sizeable steel exporter? "2018, Russia exported 33.3 million metric tons of steel, a 7 percent ... Russia exports steel to more than 130 countries and territories."
This has been reported in western media; it might be true, or it might be a part of information war. Assuming it's true, shall we expect this to be a permanent problem or a temporary one?

Hard but not impossible. Given that there's a military attache in each Russian embassy, and given the chips are sold over the counter pretty much anywhere, shall we expect this to be a permanent problem or a temporary one?
