B-31 Half Hull model

Post by Tommy »

Bob H,

Do you have any half hull models left in inventory? I know a bunch of us chipped in and secured a half-hull to be used as a plug so a mold could be pulled, and last I read you were the steward of the mold! If so, how much $$ to purchase a model? One of the NC faithful is in the market.

Thanks Bob,

Tommy

I don't think a new plug was ever made.
Bob found someone to make the half hulls, perhaps more can be made

PM him. I know he said the mold was getting rough and they did not expect future models to come out as nice as the others.

I thought someone had suggested 3D printing them. I was in COSTCO today and they had a small Dremel 3D printer for just shy of $900. Only issue is the biggest job it handles is 9.5 inches. They had some samples and they were pretty cool.

If I had a spare 900 I would have grabbed it just to play with it. I was trying to figure out if there was anything I could build for the boat.

Fellow Members-

I could produce the 1/2 molded hull for the 31 if the board would like us too. From what I've read on the site the mold needs renewal and repairs. That would not be difficult for us at Holtz Boatworks. Just give me a call or e-mail and I can get it started as long as a mold in some condition is provided, or an actual product that I could fabricate a new mold is available.

I have three or four left from the last batch. The mold could use some work, has a few spider cracks that show up in each part. A new mold may be a better option going forward. Plus the design of the mold makes pulling each part a little tough but doable.
PM me with address so I can get a shipping quote for those interested in the last few. We can either get another round made up or I can ship the mold off to Tom. Let me know what you guys think.BH

Bob, a PM is on the way; looks like our NC crowd wants three so they can all be shipped to one address. Thanks!

Hi Bob, if you see this please let me know the cost to purchase 3 of the remaining half hulls to be shipped to the same address here in NC, and who to make the check to. Thanks

Packed up the mold for the half hull and sent it on its way to a very capable steward.
Tom at Holtz Boatworks should have it by weeks end. I enjoyed getting them made and shipped
Out to a great bunch of guys. BH

I just received the half mold for the 31 Bertram. It's a little rough so we are going to clean up the mold, make a new part and then a new clean Mold to produce a better final part.

It will take us a week or so, but I'll let everyone know when we are ready to offer the new and crisp 1/2 mold. I'm also considering offering mounting boards and possibly a brass engraved plaque as options

First things first

Best to all

I have to say the half hull Bob had done came out great. In fact even if I did not have a 31 if I was a boat aficionado, it would still be great to hang on the wall.

If Tom offers it mounted consider if your wood working skills are not up to par.

I did not mean to say that the mold was not producing a good product. I just want to make a new one to eliminate any additional work after they are molded and produced.

We are going to put a flange on the mold to help with the release and take care of any of the spider cracks found in the existing mold. The end result will be easier for us to provide to the Members and friends.

Sorry if I said it incorrectly, not saying anything is wrong either way, just trying to express that it is worth purchasing. It is a nice piece to have if you own a 31 or just enjoy classic boats.
