Resta,
What is a armature? I don't understand I got the mould off the crown and brought it home, you can see in the pictures what I ended up with after I trimmed off the edges.

Resta · 10-23-2009, 08:34 AM

Frankawitz, generally for plastic moulds on all perimeter I use fiber chunks in the paste to keep borders from every side stronger and not flexible. And use "[" channels to keep mould in proper position vertical and horizontal. In your photos looks like endways are saggy. I'll make armature in that way: two-three horizontal and four vertical beams.

Resta,
Your termanology is different then what I use, I build channels for the mold to set in. then I can pour my moulding plaster over the mould.

Resta · 10-23-2009, 09:55 PM

It is as broad as it is long. I think that is not the question about terminology or little differences in technology. You have good results, client is happy, you have $$ family to feed.

Frank,
Everything looks great.

Do you cast the whole cornice/crown (as it appears from your mould), or do you run the plain portions and add the enrichments later?

Frankawitz · 10-30-2009, 06:14 AM

Roger I was trying to cast the whole piece, but after two trys I am thinking of doing just the cornice then run the crown in place, the thing that sucks is these people only want me working Saturday and Sundays or after 3:30pm Mon thru Fri. It is not the best working conditions. So now I am doing some painting of a couple bedrooms at another customers house. I tried to set up the forms to cast the piece but I may have to go back down there and apply more rubber to just the cornice part of the moulding. this is a PAIN.

rogerhattman · 10-30-2009, 08:55 AM

I believe ordinarily it is done as you just described. At least the casting will be a a little easier to handle.

I can see how your forced work schedule would be a hindrance.

Resta · 10-30-2009, 04:33 PM

Frank, if you have some discomfort casting like this what I see in the photo, try another way. Stick a molding on the table in position like letter V upside-down, that rubber edges stay in that same horizontal level on either side. Soak half bucket water with plaster, pour off upper half to another bucket. Mix first bucket and apply first splash coat. Cut proper size of burlap, mix second bucket, soak burlap with plaster and put on, trippingly press down. Take back side template and gently run to have whole piece same thickness. When you have all footage done, you’ll install them fast ant easy.

I think to cast and put these enrichments on plaster...and clean everything ...takes more time, but willco traditional way.

Frankawitz · 10-30-2009, 07:07 PM

Roger, Your right that is how they did it they ran the crown and cast the cornice, then laid it in place, when I took out the water damaged section I could see it was two pieces. Resta, I hear what your saying and I will try that and see if I can get it to work. Thanks for the information I appreciate it. I'll let you guys know how it worked out.

Frankawitz · 11-02-2009, 07:29 PM

Well Resta, I did like you said and I managed to get a good cornice moulding.
Now I am going to wait for it to cure then I am going to prime and then make a new rubber mould of the cornice, But here's some pictures of what I have.

Frankawitz · 11-10-2009, 07:18 AM

Well I tried to reform the Cornice and pour another, I keep making the edges to thick.

Resta · 11-10-2009, 11:24 PM

Frank, make back side template to keep proper thicknes and run back side in that same way like you running moldings on the walls. On other hand you can shave back side of edges with the rasp/shaver/scraper.

Frankawitz · 11-14-2009, 07:42 AM

Resta, Sounds good, I will try that, Last night I had to go down and take my bakker down and pull the drops out of the house, They are having Party's with the holidays coming so now I am under the gun, which I knew was coming, yet these people have not made it easy to do this job, so in the end I really don't care how long it takes me at this point, when I start working for these people it was August and they went on vacation and then when school started I was told I could only work after 3:30pm and on Saturdays and Sundays

and now she wants me to get it done right away

yeah Whatever

I have already lost money so why should I care if they are having Party's over the holidays
