Going to put this here because everyone needs one for the garden and around the house.
Indispensable in my opinion.
My Makita was dropped so many times off a ladder by some idiot I had to fix it.
Should have taken pictures but I didn't.
In short I did the impossible.
Took apart something that was never meant to be serviced.
The assembly that allows you to go from hammer drill to driving to drilling.
One of the ball detent springs was trashed and had to fix it.
The device was locked up.
The click thing for the clutch was broken.
No replacement for it and don't need it.
Three ball detention springs and ball bearings.
Wee screws other mystery parts.
All got to sandwich together.
Used magnet to keep track.
Put together wrong first time.
Took apart and got it right the second time.
Whole assembly costs about thirty dollars gears and all.
Couldn't get Chuck off had to squirt with kerosene and let time do the work.
Working fine now happy as a clam.

I love a cordless drill. Love cordless anything; cords seem to have a habit of getting severed when I use a tool.

nothing is made to be serviced nowadays. I am glad you could figure it out and salvage it. well done.

I have a couple of old DeWalt 12 v drills, a Makita 12 v hammer drill, and a slightly newer Milwaukee 12 v, which I use the most, because it is smaller and lighter than the DW. I never need those oversized 18 and 20 v models - those are for commercial purposes, and even in my workshop, when assempling an entire project, with dozens of screws and holes, I never run out of juice, with just one extra battery in the Milwaukee. When I need some thicker holes, or when I take it outside, I'll use the DW. I replaced the batteries in those just once, in over 30 years - the replacements lasted better than the originals, probably because they've improved batteries.

I just had my 3 hp Ryobi router, in my router table, bite the dust. It wasn't the motor, but the threads of the system that raised and lowered the router, stripped, and like the part you describe, @worth1, it is not something you can repair, and, being just under 30 years old (you know it was old, because it was made in Japan, before all the companies moved their factories to China!), the part can't be found any longer. So I had to get one to replace it - Triton TRA001 - plus I had to replace the acrylic base, that sets into the table - something I was working on for much of last week! All done now, so back to the seeds! lol

When it comes to parts with threads I can run just about anything you have with my lathe.
But sometimes it isn't worth it.

The problem with the threads is that it runs inside a part, that is not something that could be really be replaced, unless you had the part. The male threads could be replaced, but but not that, and it seems the female part is what stripped. As old as it was, that router didn't owe me anything!

One good thing - this one has a rack and pinion system to lift it, so it should outlive me! At least that part...

A friend of mine liked my Makita drill but couldn't afford one.
I told him he couldn't afford junk.
Well just the other day he bought a set like mine.
It was on sale 30% off and then he got a 25% off military discount on top of that.
It pays to wait.

Been switching over to Milwaukee cordless drills and tools because there always seems to be a sale on them if you wait long enough.
Plus I think there maybe a little better quality, not that I'm knocking Makita.
Some time ago I bought a Milwaukee 12 volt cordless screwdriver thing that has the lug to pop in different types driver bits and it has an adjustable clutch.
It came with two 12 volt 1.5 amp hour batteries that last a pretty good amount of time.
I use it to trim out devices and such because it's light weight.
The have 3 amp hour batteries and 6 amp hour batteries for it but they're expensive.
Well today at Home Depot they had 2, 6 amp hour batteries for the price of one.
I couldn't resist and I needed them and was waiting for a deal anyway.
As far as I know they are on sale everywhere.
They also have 4, 3 amp hour batteries on sale for i think $158 but I didn't see them and didn't want them.
Mathematically the 2 6 amp hour batteries are the same thing but only 2 batteries instead of 4 to keep track of.
50% off is a good deal.
I'm charging batteries at home because I can't afford to get them stolen at work.
And I won't charge the overnight in the house because I don't need a battery fire.

We use Milwaukee at our home. Mt husband can fix about anything. Started as a machinist then a mechanic and now manages industrial mechanics. Which leaves me very fortunate. Anytime you can fix instead of buy new you save so much. Congrats!

I have a couple of 18 volt Makita drills and about a dozen 18 volt 5 amp hr batteries. One is a hammer drill. In addition to using them for drilling I also have several Power Planter earth auger bits. The drills are so strong I could break my wrist if I am not careful while using the earth augers.

I also have a Makita handheld vacuum cleaner and a couple Makita flashlights/spotlights and a Makita air pump for inflating tires and a couple hedge trimmers.

The reason I have the Makita tools is because I have their batteries. The reason I have the batteries is that they came with the Makita 36 volt string trimmers (two batteries on each). I have four 36 volt string trimmers each came with at least two batteries, some came with two extras for free. One of the 36 volt trimmers also accepts a steel blade and an extended hedge trimmer. There are other attachments that I don't have. I also have an 18 volt Makita string trimmer that I no longer use. The Stihl two stroke and the Honda four stroke string trimmers also sit unused.
