Shortening central rod

Unread postby Dr Jacoby » Tue Feb 20, 2018 8:49 pm

I'd like to cut about 1.5 inches off the central rod in my 20L Braumeister. Any recommendations on the best tool for the job? The section I'd be cutting is the threaded bit of the rod but I'd like to be able to still screw the tightening nut on and off on the remaining thread.

So I can use a floating mash cap without a hole

What about all the little holes ?

If you really want to do it just unbolt it and cut it using a hacksaw plus a packet of spare blades

Yup - you will have to take it apart.

I cut stainless with a 1mm disk in an angle grinder - take about 10 seconds. A hacksaw will test your stamina and probably take 10 days.

Previous comments still stand tho' " DON'T DO IT" - "Why?" - "Noooooooooooooooo" etc etc :D

The hole in the mash cap tends to leak and eventually the mash cap sinks

Not sure what you're referring to. The mash cap has one hole so it can slide down the central rod.

If I could hire something like this threaded rod cutter I could shorten the rod without creating burrs. The only question is whether it would fit between the rod and the perimeter of the Braumeister. The videos I've seen of the cutter make me think it could work.

I don't want to take the rod apart.

If you want to cut it, why don't you simply unbolt it from the base and use an hacksaw? On my 50L BM, if I tip it upside down I can the central bolt that holds the rod in.

Not sure what you mean. Grains are within the filters. The mash cap floats on top of the mash liquor, which is above the level of the filter. It doesn't come into contact with the grain. The problem is the mash liquor seeping upwards through the whole in the mash cap, causing it to sink.

I am still unsure what the problem is you are trying to solve? And fear you are unleashing more issues than you are solving.

How are you going to make a seal at the bottom of the mash tube for the pump to operate?

If you want to talk this through happy to phone/Skype -
just pm me.
