Had a customer bring in a new set of Moser axels for a custom build he's working on. The axel flanges OD where too large to take a rotor for the disc conversion and the center hub was stepped with a larger OD as well. A very simple and quick job. He also dropped off a aluminum bell-housing the had cracked in the typical area. I have done many Chevy bell-housings for this guy in the past. I used to tig them up only to find out he would blend down the weld to original profiles, so I changed my technique a few years ago saving time and saving him $. I always give the option of welding techniuqe to my competent customers as well as my recommendations. I keep the spool gun plugged in and stored on the 350-P so a simple gas connection and a pull of the trigger(spool gun) and the machine switches over. Miller's gun on demand feature is a time saver.

Gov job parts for day boss... for bad azz bobber.. axle sleeve and bushing wheel spacer fender spacer forward break control bushing
Been burning both ends of the candle home/. work called out to measure up parts at one of the bosses other buildings . real estate agent came last night been painting getting house make ready ect.... have not had a chance to sit read the groups.
Ill prob end up make a few more parts as the rest of the bike is being put together . This pic is the one that my Boss was originally inspired to build his . The Guy who ones this one lives in Germany and when he wrote im to inquire he was honored and sent a few of the details of the bobbing customizing of the scooter . However the guy did leave of the tricks that needed to be figured out. It will be an SS pan head motor on a rigid frame ... The theme is pretty much the same but his will have a lot more details in it .

Damn fat fingers. I meant to upload not reply. The axel to the right now plays with the rotor. As you can see the left won't play yet its .084 over.
Less than .000.5". The hub also required the removal of a .040"step for a face to face fit. The material was fairly hard but a nice finish with inserts.
I've been really please with the size of the lathe 14x40 for the general purpose machining we do.
This is how I prep the cracks on a aluminum bell-housing. In the past, grinding would contaminate the weld zone so I've been drilling to remove material to replace with weld.
Not shown in this picture where to "stop drilled" holes at the termination of the cracks.
The mig technique put down one single bead with good penetration and plenty of bead to blend down. The bell-housing is then re drilled from the back side using the same method and welded. This has proven to work many times in past repairs that required bead blending. Total time was 15 min. saving the customer money vs tig welding.
It should be noted that a broken bolt ear or other structural areas requiring repair, I would tig the repair.
A funny story behind this customer, we have known each other for the past 30 years. He has been in the automotive repair business for himself at least 35+ years. When we first met he brought me a suspension component that required welding and it was filthy with years of grime on it. I informed him that I would have to charge him time for the prep work required to complete the task. When he returned to pick up the component, he was beside himself with the cost of repair as I had more time in cleaning than welding.
I stood my ground and word got out that I was expensive and picky, but the repairs have held strong. Now most customers bring me clean items for repair requiring minimal effort for prep. No longer expensive just picky hahaha.

Is that rotor full seated in the last photo? seems there is no hub protrusion past the face of the rotor for the wheel to center on. Relying on the wheel studs to center the wheel is typically not the best option as it often leads to the wheel being of centered slightly.

Not fully seated in the photo,it was when I pushed it in but moved when I let go for the photo. Protrusion of hub is about .120. Good eye there bmw rider.
Finally got started on my acute grinder rest system today:
The most fun and challenging for me was making the grooves in these:
I had to grind a tool to cut the groove in the face of the part using my lathe. After a few trials the tool look like this:
The groove is 2mm wide and 1.5 mm deep.
The gooves fit the supplied o-rings pretty good:
So I have made a start. I know this is not super advanced or anything but I am pretty happy with the result
Never made a groove in the face of a part before.

I hope you show us the rest system in use, once it's finished, so I can understand what it's for.
It looks like you're well on your way.

Will do once I get more done. It is a tool rest system made by precision engeneering. Going to be fun project to finish the kit, but I will have to buy a mill so it will be an expensive tool rest.
