Mold making

4/15/19

I have a Chinese table in my shop missing a very heavily carved section of molding on the rail. Its probably about 3-4" in length and width, and maybe 7/8" thick. It is basically deeply carved fretwork. I can carve it by hand if needed but the client is open to a mold being made. I have another rail to take the mold off of. Any thoughts/recommendations as to what to use?

Doug,

I am aware of that and told the client it should be carved etc. He requested the mold/cast to keep price down. I will do it as to not damage the original so that in the future it could be carved.

We use a silicone product called Knead-a-mold. It's more solid than the pour-on molds and can be used on a vertical surface. Cures fairly quickly. Then we use Mohawk Epoxy Sticks or similar products to re-create carvings or moldings. If you google silicone molding products there are several of them.

I would tell the client to pay you to carve it, or you can destroy the table for him at no charge.

A culture of cheap, in the midst of the richest nation on the planet, makes for people that value their money more than things that are really more valuable than money. They should not be entertained.

Cheaper is not better,it is only cheaper.

Get a reputation for working cheap, and you get to do that for the rest of your working life.

Pete:

My question would be: What is the REAL labor and material cost differential between doing the carving in rosewood vs. making the mold, casting the molded piece, and then trying to get the molded piece to look like rosewood? For a 3-4" piece, it sounds like more trouble to make a casting, fit it in place, and finish to match.

Not sure of the antiquity or value of the table, but if there is any, then perhaps your client can also come to value the difference should he/she ever come to sell it; a restoration vs. a cobbled repair.

Thanks to all who responded in regard to making a mold.

I have since talked with the client and the final choice as to what direction to go is mine. Money is not an issue.

David- thanks for the lecture on cheap. I have had plenty of clients that I have not "entertained". Seems to be the younger generation, that I am actually a part of, that have given me the most headaches. But after over 20 years at this, my patience wears thin at times.

Maybe consider laser scan and 3d cnc carve. Then hand carve and finish the tight details.

Pete- I did not mean to wear your patience thin. I understand what you are saying. One never knows whom one is addressing here on Woodweb.

After 45 years of my various rants, I get few calls for bargains and tire kickers. While I do my best to make a good impression, I do not entertain those looking for cheap. Just because they got gouged on some other endeavor does not mean I must walk on eggs. The fact that Walmart exists and has changed this nation does mean I have to fall into line with that thought.

We have succeeded by avoiding the masses.

We are expensive because we are good. We are proud of the fact that we have trained ourselves to be good. To be the best. This pride is fed by doing the carving and not by making a mold. Carving is a direct extension of our work. Mold making is not.

This is just the way I see it. Nothing personal towards you at all. I have seen your site and you know what you are doing. You are capable of making either choice.

Carving preserves the value of the piece, even enhances it since it has less value when broken. Mold making just makes it usable, maybe presentable. Since the table was made by people like you and me, I suggest it be preserved with the new carving. This respects the table, the makers, the process and the industry. One person's idea of the value of your time is immaterial to the whole.

Dave,
You didn't wear my patience thin at all and no offense taken. Its the 2 clients I have dealt with and gotten rid of the past few weeks that have done that! Both unrelated to this table/mold thing. Long stories. But back to the mold- Ive been around the antique world for many years so I fully understand whatever direction I decide to go. The antique world is the greasiest business. If the work is done well enough, its all original right? Many stories on that! Honesty and antique dealer are words not used in the same sentence. Ill leave my rant at that. The client though is one that I value for reasons outside of the work and he values my skill set and opinion as well. I have a pile of work to get through before I touch this table so we will figure it out.

Busy is always best. It helps keep everything in perspective.
We could easily swap stories about antique dealers......

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
