This Blog is primarily intended for Anthony (AKA anthm27) but for all to enjoy if so desired.

A bit of history.

First up I was enlightened by George Coles back in 2015 when I was first requested by my wife Aurora to make her a Sungka Board (AKA Mancala) which I had absolutely no idea about, so knowing George was in the Phillipines I hit him up for some info.

So acknowledgement to George for his input.

You may wish to check out some of his projects, some most impressive from my point of view.

What George said if you cannot read it.

Re: Sungka board game
Message

Hi Robert

The game has many board sizes that I have seen around Asia. The holes vary from 50 mm – 100 mm. The determining factor is the size of the shells used. I have seen the holes as big as 150 mm. The most common I see is between 80 – 100 mm holes.

Hope this helps.

Best regards

George

EOM

As you can see the overall dimensions are a personal choice.

I made my template with the available holesaws I had.

One hole saw was about 65 mm and the other about 89 mm

I should have used a bowl cutter but it met with a nasty accident and I was unable to get it repaired at the time. So being poor I modified a Cove bit by fitting a bearing.

This works OK for me but it means more sanding on the base of the recess to get it flat.

The templates I made from MDF and the reason there is two because I found they were easly damaged if you withdraw the router with the bit spinning.

The overall size of my finished Sungka boards finished was 725 mm x 190 mm x 28 mm min, to whatever thickness you choose
As George indicated in his reply to me the size of the holes can vary, hence the overall dimensions will be determined by your size choice and hence the length and width will vary accordingly.

The template is attached to the board material by four screws at the ends, the area may will be cut off later, again a personal choice.

To cut the resesses I used two initial settings, one with the bearing engaging the template only then the second engaging the template and material being cut.

In my case continuing down to a depth of 20 mm.

So that should cover it Anthony, otherwise ask away.

-- Regards Rob

May I choose not to enjoy anthm27... nothing personal but the missus might have words?


..... about 65 mm and the other about 89 mm…..
- robscastle

Damn, with modern technology you’d think they’d get the measurements exact… not about…

Sorry rc, the missus already asked the surgeon to go for the head instead….


..... but it met with a nasty accident and I was unable to get it repaired…..
- robscastle

PM me for the details of my surgeon!


.... works OK for me but it means more sanding on the base of the recess to get it flat…..

Rob, if you ever find rc, tell him to open his door and charge the freeloaders for the Sungkas and you’d be able to supplement one of therse Arbortech units... won’t keep the visitors at bay but may help reduce production time/costs… and you won’t have to pay exorbitant shipping costs…. go USPS, my next share portfolio investment.

..... attached to the board material by four screws at the ends…..
- robscastle

Ever thought of double sided tape… you won’t have to fill the screw holes with pink Builders Bog!

In my case continuing down to a depth of 20 mm.
- robscastle

Thank god you are a perfectionist… 20mm… NOT about 20mm.


..... So that should cover … Anthony….
- robscastle

A bucket of water would have been easier and quicker!

What do you scream when you win a game??? Sungaka Mate!

PS. What’s all this crap about???... I’m in pain and I like to share…

-- If your first cut is too short... Take the second cut from the longer end... LBD

OK OMG here we go!

choose not to enjoy... well I set you up good and proper with Daves Knife in your red high heels! haha.

Sloppy tolerances ....I found it hard to hold the phone and tools at the same time.

Surgeon ...When I first started wood working I bought a very expensive bowl cutter from YKE CT and ruined it on the very first go.

Freeloaders ... I was intending to sell them for $50 bucks each, expensive but not much to be made now.

Ball gouge ... yep saw them when they first came out but they were out of stock for a whileand I havent bothered since.
DST
... yeah I have some but was reluctant to use it on high impact routing see template gouge.

Perfectionist, by choice … didnt want to penetrate the base.

The scream ... Asked Aurora but could not understand what she said, kicki or something like that certainly wasn’t anything like Mate!!

In pain ... keep up the one finger typing!! you should feel just like me!!

Right O gents,

With Philippine Sister in law and 10 year old nephew on holidays and staying with us, SUNGKA FEVER has hit big time here in Hong Kong.

Progress so far,
We went to the beach this morning (yes beaches here in HK actually beautiful, sing out if you want to see pics) we collected small rocks and shells for the Sungka pieces actually I suspect we picked up more than the 98 required pieces.

For the template I,ve laminated two bits of 8mm scrap ply together. I went to the Chinese Hardware store, (well hardly a hardware store) But they did however have 89 mm and a 64mm holesaws.
With Sungka fever its forwards and upwards with the scrap Chinese mahogany I found and seen here

All this in 30 degree Celsius heat, the beer should taste good this afternoon.

Rob, good to talk on the phone this morning and thanks for the tips.

Regards
Anthm27

PS. LBD if your reading , your definitely not getting near me. I do however get your sense of humor

17.30 here and its way past beer o clock, I thought best I post the progress before happy hour.
Getting the 16 round pieces out from the inside of the hole saw took the time. (I end up oiling the inside of the hole saw which worked a treat.)
So this is the template, still work in progress.
Cheers

I hope Rob you don,t mind if I continue to hijack your blog,
Today basically finished my first attempt at a Sungka board, I,m definitely not claiming your technique or design rights
I wont post it on projects until I,ve given it some wipe on polly,
Very enjoyable.

Makes sense having it all in one location.

Your work Looks good, I like the radiused edges and final profile.

What did the final depth finish up as?

I bet Liam was rapt!

BTW I found this as well:-

Thanks Rob,

I set my plunge router up to take three passes to get it to 20mm, Its got a turn buckle thing to easily adjust for three depths of cut,(see pic) I then ditched the template and did a final 3mm cut to finish at 23mm deep.

All round overs at the top, edges and holes was 1/4 and the half round underneath was bigger at 1/2 inch.(maybe can see the bottom half round in the pic)

I thought the slight burning was going to give me grief but it sanded out easily, Due to the darker grain through the wood the burning looked worst than what it was (see pic)

Seems they couldn’t wait for the wipe on poly, they’re away. Cheryl with fond memories of her childhood and Nephew Alexi getting a good taste of Philippine culture. (he has definitely played it before though)
Awesome Rob , thanks for the idea from the start,
(Liam got the truck, great memory for names)

This is the 33USD bowl cutters I bought and used here the only thing is the bottom bearing blew up completely, So not sure if there is better out there.

Anth

EDIT. I see these for 66 dollars , seems same as yours, seems they made in italy, probably better??
