Looks like you got a Optimum milling machine, is that BF20 ?
Did you cut all the sheet metal parts yourself ?

And also, great work

yes. its a bf20l.
and yes. i buy simple sheets and cut them self. my tools are a simple lever shear, flex bandsaw, some bender and a old bosch belt sander.

I'm a programmer by trade, so i could use a cad and buy laser cutted metal, but i won't work with computers after the whole day on it.

------------------
Last complicated parts are the telescopic lift cylinders.


They are located in the big slots inside the frame.
Big? When you plan and estimate the sizes of the cylinder, the slots gets smaller and smaller

Seldom I've planned so long for a single part. Maximum and Minimum Angles, posibilities in machining, needed pressure to lift, sizes of the cylinder, rods and pistons and so. So much interdependent variables. I think, the fifth or sixth plan was the base for the first try.
I'll show you the second and last attempt

I thought the parts ware laser cut
I also have a BF20L that I converted to cnc , and I love it.

Well, after planning, the doing was a simple turning job

the guard rings are very small.


seals are simple o-rings




big thread on the lid






Fits perfect






To lock the trough in open state for working on the hydraulics are at the big ones simple Us wich will hook on the back plate.

So do i


Works


Here you can see the last part of the cylinder with the flange. both from stainless to be able to weld. All other parts are from aluminium.



the original have a maximum tilt angle of 53°.

almost



later, after some test and measuring, i'm able to raise the size of the guard-rings. that brings a lot more stability.

Last post so far

The exciting parts are done. Followed by things i have to do.

Hydraulic arrangement


Many stainless sheets .3mm or .5 mm are cut, bend and welded to build the front.



The bonnet is parted.







on the back the massive airfilters


tank


battery tray


after all the yellow some belaz blue



and, tradional for me, the last thing: The cabin







Et voila. Almost completed




Actually the one and only clip with my Belaz 7540 Mining Dumper working.

(Don't mind the unscale Loader )

Here it is

Now it's waiting for Spring to make a better clip and get some interieur into to the cabin.



Thanks for your Interest.

Maybe you'll watching my thread to build a more scale Loader
