Happy new year all

I did try blocking the fan off but it wasn't doing what I wanted.the oxalic chamber was too small.when I can I'll try to put a video up and you'll see the difference.it was also my winter project while I wait for the season to start again

Once I sort a better seal for the lid I might make a few.it works great but I want it as good as it can be.ive spent the last eight weeks ironing out problems and still not quite there yet.one of the main problems is getting parts to fit.i ended up having to use two separate blowtorches.i used...

Copied it off one I saw on youtube.when I have time I'll try and put a video up.it really pumps the oxalic out.if you've seen the homemade ones like the one above you'll know what I mean.still having a small problem with the lid sealing tight but with the amount coming from outlet pipe it...

[/ATTACH][/ATTACH][/ATTACH] Here's the vaporizer I made.it's a beast.the amount of oxalic being pumped out is amazing.its taken weeks to build with so many changes and improvements but well worth it.just a few seconds per hive now and job done.

One of my sites is quite a large area of bramble and nettle.i strim it three times during spring and summer.i use a brushcutter blade or circular saw blade which makes short work of even the most overgrown areas.

The first queen I ever marked got covered when the marker pen let a lot of paint flow out.the queen got covered but she was so easy to find on inspections.

I de threaded the grub nuts after taking apart to clean so will try tapping and using sturdier bolts but there's not much thickness to play with so if it doesn't work I'll tig weld the barrels on and clean from fan end where the bolts don't suffer from the heat.the vapouriser does work well if...

Did you get round to trying that fan after

The sawmill in usk is reasonable but you'll need to dry it and plane it

Huge beech came down and smashed a double brood to pieces sunk another hive four inches into ground and knocked another three over which I salvaged.glad I wasn't there at the time.it was rotten in centre but looked fine on outside..

Bought another 100kg from morrisons at 44p a kg.thats my sixth or seventh visit so far.just hope that I don't need to feed the thirty something hive on the heather too much.

It was only a faint wisp of it.i could feel it slightly catching my throat

Did some double broods earlier with two 1g tabs with no issues

Make sure the mask is tight on your face.didn't have a good seal on my 3m one the other day and could feel the vapour hitting my throat

I heat barrel separately with blowtorch to start and leave vapouriser going for a couple of minutes before using oa.most of the time I've had it on full
