MAG DRILL repair

[Memmeddu]

Hi everyone as for everything I want try to make it happens that I found a bargain down the road
(Engine driven welder I was putting the things together when I found my genset or the engine driven air compressor which I could get one soon but it's not sure yet )
Back to the topic the story repeated I was making a magnetic stand when I was reading a Facebook group about welding hobby
A guy posted the pictures of a Chinese Z4030 magnetic base drill thing
He was pretty frustrated because the gear housing has been cracked while using a big anular cutter
I've contacted him via messenger telling him some tips about repair it so he tried but had not success
He offered it to me for free just shipping costs 18 euros
That's the situation the gear housing is divided in two halves and it's going to crack in another spot .
(I'll upload pictures down here)
My idea is to make a steel enclosure to shrink and secures the parts together .
Wire brush the zamac or magma or whatever cheap and brittle zinc alluminium alloy has been used to make the housing .
Use the center punch on the inside of the steel enclosure and after having press fitted the parts use some chemical anchor to keep all together
Now I would like to know how you'd proceed in my same situation?
Because the in my opinion a simple hose clamp would be enough
I've made a sketch with the measurement of the enclosure for 3x60mm flat stock
My brother in-law gave me an off cut from a 5mm sheet so the measurement would be 4mm bigger

Thanks in advance

If you made a horseshoe shape with long ends (to screw to the lump outside of the gearbox),screw this ,space permitting to the casing from inside,the long ends screw externally to the lumpy bit.

That's was the first option

That's was the first option

And a second?

And a second?

The second Is an enclosure

I'd go with the steel band option, one way or another.

Reminds me of a band I wrapped around my vw gearbox,as a recommendation for off road buggies,back in the day.
This was a preventative measure,don’t know if people had tested it to break point.

It's a solution, and a cheap mag drill.

I've put together the parts and welded an enclosure
It works
Tomorrow I'll finish it up

 

[Memmeddu]

So yesterday I've filled the housing band thingy with some chemical anchor
Today I've used some filler and used an angle grinder to smooth the surfaces .
After doing that I've cleaned it up , masked the motor housing and the spindle , painted it using high temperature black paint (I have those paint cans since I've painted my engine driven welder exhaust system in 2018 so I have to use them prior to their expiration)
Now I'm waiting for the paint to be dry and I'll start reassemble the drill .
It's not pretty but at least it's cleaner

Necessity is the mother of invention.
I like a challenge, and I applaud your efforts.
For me, it has always been about the good feeling one gets from achievement.

Same here the more the effort and the problems I have to solve the better I feel once finished .
Now in this case I was wondering about getting a mag drill for a while ,made a electromagnet , and I was seeking for parts
@gaz1 helps me a lot with ideas to make things I need but unfortunately it requires time to seek parts and to make the things work .
I have to mention him so he would be happy to see that sometimes I manage to complete something

I have to many ideas and things I would to make but unfortunately I'm not able for a reason or for another .

 

[Memmeddu]

I've put it together and I should improve something tomorrow I'll upload pictures

 

[Memmeddu]

That's the ending result
It's ain't pretty but it's functional
Expenses
MAG drill_______________0.00€
Shipping_______________18.00€
Sheet metal_____________0.00€
Chemical anchor________4.00€
4 M5 stainless screws___0.20€
Filler____________________0.00€
Paint____________________0.00€
Actual total cost________22.20€

I have to replace the power cord and plug with proper H07-RNF 3G1.5mm² and CEE Blue plug .
The original one becomes way too hot in too short time .
And I have to buy a Weldon chuck adapter....
Which is expensive I'll probably ask to my local machinist if he can make one for less money

I don't know , I was thinking about making a review of it on the forum because being broken and repair I had to disassemble and I've seen how it has been put together
It has many things that could be improved
I don't know
Let me know if you'd like a review of this drillamathingy
