I also have compound bow but I need a new string and cables. The "bobbins" on the cable broke off and the string got lost somewhere in the past 15 years, any advice on where in our RSA?

Hallo Wildeboer
I got my nylon strings from a company in Alberton named Die Blou Meul phone number 011 907 1107 (International callers should phone +2711 907 1107) and ask for Lucas or Jacques. The cable - you can ask any cable company - in PE I have mine done at The Cable Guy - and they will sort you out. One problem with mine is that it is normal plastic coated and not the durable black coating but it works fine. The plastic wont last though. But just as a point to start that`s where you should go. PS. Where do you stay in SA? Me I am from PE.

Hi Doem, I am from Colesberg. The problem is that I dont have a decent sample of the cables, both cables on my crossbow are broken. I basically need a sample of the cables and string to have new ones made up.

Hi Wildeboer
If you scroll through this forum a guy called OddJob has put all the specs with photos so you can just download those and send it to to Lucas at the Die Blou Meul and they can make it up for you. Surely there is a cable manufacturer in Colesberg that make the cables for you. If you come through to PE you can always go to The Cable Man in Kempston Road.Let me know

Greetings to all the crossbow enthusiasts out there.My name is Garth and I'm from KZN,South Africa.Im very new to crossbows and have managed to acquire these two crossbows by a company called Crisbow and would like to know more about them,especially my Mk1 model which I can't find much info on except that it's the first model from the 1960's apparently.Thank you.

Welcome to THR!
I haven't seen one of those before. Any further pictures of the crossbow and any boxes or manuals would be greatly appreciated.
I'll send you a PM when I get back from the range, since I am also South African, now living in London. I spent a lot of time in Amanzimtoti and I miss the beaches!

Awesome speaking to a fellow South African.I don't have any of the boxes as I bought both bows second hand from two separate guys and got only the bags with them.I'm surprised at how they are both in excellent condition.Will send more pics a bit later.

Thanks for the extra pictures, I find them very interesting!
The only two items that look familiar are the stirrup and the little plate that goes between the stirrup and the prod (the bow). That stirrup is the same one on the the MKIII and MKIV Cheetah and Quadro, and it is made from glass reinforced plastic (GRP).
The little pate was present in some versions of the recurve Cheetah Crisbow. The Cheetah and the Quadro shared a common GRP frame but the Quadro had a compound prod. There were some differences between the buttstock lengths also, amongst the various models.
Your MKI is most similar to the imbuia stocks of some of the Crisbow models. I have a Quadro with an imbuia stock but that one has a steel stirrup.
This is the Crisbow Quadro 2000 with the imbuia stock: (Edit: just noticed you also have one of those)
The thing that fascinates me about your MK1 is the trigger mechanism and the latch and sight assembly. I assume the safety is the lever marked here:
Am I right that it engages as soon as the string draws into the latch?
Do you happen to know if the bag came with the bow, or if it is a rifle slip that the previous owner happened to use for that bow?
Very interesting all the same!
That reminds me I need to update the Crisbow thread I started some time ago because all the Photobucket images are gone...

I also found a wooden stock(Imbuia wood) and recurve prod in a pawnshop in Bloem a few years ago. Made a new string and its shooting quite nicely now. I also have a Quattro still in its box, the camo model. The fletches on the arrows are buggered of course but otherwise in pristine condition.
I still have a black Quattro which I shoot once or twice a year, open sights of course.
All the crossbows were sold in a box, bags were something after-market. I know as I bought 2 crossbows over the years, brand new from sports shops in Bloemfontein early 90's. I had bags made for them as there was nothing commercially available...
I'm situated in Colesberg, on the N1 Highway.

Maybe worth to mention, I met the guy who build the first series of Crisbow crossbows. He is now living overseas but slept over in a guesthouse a few years ago near me. I have a gunshop and he visited me for a chat & coffee.

Yes the safety automatically activates when cocked.I also find the sight adjustment very interesting and old school.The bag came with the crossbow.

Hi Wildeboer.
That must have been very interesting.Did he mention what year exactly was my Mk1 made?

Hi Garth,
We only talked about the crossbows in general. All his crossbows had wooden stocks and later he sold the company off and emigrated due to politics. He was quite surprised when I showed him the plastic stocks....

Very interesting.Thanks for the reply.

I updated many missing images to do with the trigger assembly.
Also, there's a small thread here about converting a blank Picatinny rail to fit a Crisbow, since the plastic dovetail rail on the original Crisbows is not a quality base for mounting rings:

I have some updates here.
Firstly, if you've lost the stirrup for your prod, you can use the attached file to have another one CNCed from aluminium and anodised black. I am not by any means an expert designer and you can see by the drawing it is novice, but I can verify that the machined part does work, because I had it made and tested on one of my Quadro bows. I designed it in Fusion360.

If you need to replace the buffer inside the trigger mechanism, you can have one 3D printed from thermoplastic polyurethane (TPU) with an 80% infill. See the attached STEP file.
This is one I had printed using Craftcloud online. Note how rough this particular print was:
I have tested one of these to 70 shots and it has worked just fine. TPU has a little bit of flex to withstand the force of the cable catch being pushed forward without causing significant indentation on the buffer.
Note that I previously assumed all Crisbow trigger units are the same. This is not the case, some of them have a bulge at the base of the cable catch arm. That's why this buffer has a triangular void towards the base. This buffer should work with all MKIII and MKIV crisbows.
