I've tried to search, but not too successful.

I have a Benro C068 tripod that I'd like to cut about 3 inches off of the center column so that the ballhead can fold between the legs instead of sitting on top.

Would I be able to do a nice clean cut with hand tools?

Thanks for any tips or pointers.

I would say no. Carbon is made very similer to fiberglass. And cuting fiberglass never stays nice for long. It allways starts to chip and fall apart. If anythig might work it would be a waterjet. It can cut the cleanest of cuts and may be the best way. So i guess it really is, yes it can be cut. But I would never suggest it.

i'd put a couple of wraps of electrical tape around column and use the edge of the tape as a guide. i would wrap a rag around the column and clamp it loosely in a vise and cut with hack saw.

i was able to buy a short column for my benro but it cost me around $45. it's worked out for me because i sometimes use the hook when it's windy.

A very fine toothed saw.. Ed's recommendation of a hacksaw is a good one in that regard.

After the cut, there would be an epoxy resin you would want to coat the cut end with to help prevent any further damage, but I'm not sure what type.

I've never worked with carbon fiber but work with fiberglass all the time (I restore Corvettes for a living) and I'd suggest the very fine toothed saw approach, such as a hack saw using a 32 tooth per inch blade, which is made to cut thin wall tubing or pipe. A better option might be to buy a coping saw & blade meant to cut ceramic tiles. There is a blade that in actual fact is more of a file than a toothed blade, so it won't shred the fibers. Before making the cut I'd use the tape trick, wrapped tightly to both protect & act as the guide, cutting right next to it. I'd also only cut part way through rocking along the side of the tape as far forward & backward from the top as is easily done, going all the way around by rotating the part as necessary, and continue doing this until through. After that I'd use a very fine sandpaper, preferable a wet & dry type around 360-400 grit with soapy water to sand & smooth the area with a slight radius (or bevel) to the end, inside & out. That should prevent any issues with chipping, fraying, or rough edges. If you go with the fine hack saw blade go slowly & do it the same way I suggested for the coping saw. USE LIGHT PRESSURE on the blade, don't rush it.


A skill is developed through constant practice with a passion to improve, not bought.

I emailed Benro, but they seem slow to respond. Strange that they sell this tripod with 2 different center column lengths when purchasing the "kit" option versus "legs only", and not stating this very clearly.

Thanks cicopo for your expertise! I will definitely keep your technique in mind if I decide to go through with it.

Someone from another forum also pointed out the following link which has a CF cutting faq at the bottom of the page in case anyone is interested:

Anyone has the c068 kit center column and want to trade for the leg-only center column? ;)
