Parts removal advice.
« on: April 25, 2016, 09:32:46 AM »
Hey Lukasz could you give some advice for removing the rocker arms for the Mercedes D.IV? I have managed to remove most by cutting the base after breaking a few cutting closer to the part. But even with a brand new scalpel blade I cant seem to clean up the part. They keep breaking into 2 or 3 pieces. Any hints or tips please?

And it doesn't snap these small pieces?

I use a photo etched micro saw for those kind of tasks - mine came from Voyager.

Definitely use a saw. I use the same thing Justin recommends.

For me a fresh old-fashion razor blade works fine. Like those from Wilkinson:

And for more solid resin bits I use a Czech razor-blade saw:

James,
    I use the same razor saw that Prez recommends, like it so much I ordered a second and a bunch of spare blades. Two years later I'm still using the same blade. It has a fine edge on one side and ultra fine on the other. A great little product and you won't need a second mortgage to buy it!
Cheers,
Lance

Okay will try. I used a new blade in my scalpel and could cut the part out at the base. Any closer to the part and it snapped into multiple pieces. Unfortunately as I try to clean up I'm breaking them still. Thanks guys for the help.

A razor blade is thinner than a scalpel blade, this makes the chief difference - no stress is applied to fragile elements when cutting them off.

For me, the Razor Blades work without problems as long as they are sharp. :D

Cheers,

My method is like this:
1) separate the casting box into parts containing single lifters
2) use VERY sharp Olfa knife to separate lifters - very gentle cuts, one by one up to full separation.

I'll send you some supply casts for training :)

All the best, Lukasz

Thank you everyone and thank you Lukasz. When I got home from work my latest order was here and I robbed one of the new sets. The very fine razor saw worked perfectly for me, well at least on one piece. Will do some more tonight and hope to have pictures soon.
I can not say enough about Lukasz products or customer service, he's awesome. And I cant thank you forumites enough for all the advice and help :)

As an aside, I often cut/saw small parts off inside a bag. I cut both ends off a sprue packaging bag so that I can get a hand in each end; one to hold the resin part, one to cut. Any small parts that ping off are caught in the bag.

Now that's a clever idea. Hereby appropriated!

    I think I'll join the "Baggy Set" as well. I will miss all that time crawling around the floor with Wonder Dog helping in the search for the latest tweezer, saw, or knife ping projectile though. For anyone that's built a Fee or another subject with those lovely little control wire pulleys to drill you'll immediately understand the need for a better way! A few days back I launched one and gave up the search after a good half hour. I then spotted it, laying in the recess of a Data File Binder in a book case at least 5 feet from where it originated it's journey, can't count on that every time! ::) ::) Thanks for the tip, Justin.
Cheers,
Lance
