  1. Piers, I reckon it’s the longer pipe that’s caused it to soot up. I’ve had mine running for two years now, the shed isn’t too big, 2m x 3m and I run it at slow speed otherwise it’s too hot. It hasn’t missed a beat in the time.

    on the subject of silencers, my homemade stainless vacuum flask works really well and cost next to nothing

    I must be ahead of the curve for once, I bought this Ministick lazer cut kit from Kits123123 (Wayne) off Ebay a couple of weeks ago.

    Bob, I did a search on that seller ID but nothing came up, could you give me a link, please?

    Thanks Bert

    Piano wire is no longer the cheap product it used to be, good stuff is worth the cost, The three suppliers mentioned above are good but beware buying on Ebay.

    Have you tried looking for piano wire on eBay? Or are you just giving a general opinion?

    Interesting silencer you've got there Bert.

    I assume that you drilled the holes in the outer layer. What did you do to the inner layer?

    I started by drilling right through the bottom with a 14mm drill bit into the space where the tea would be, I then drilled at random a lot of 6mm holes through the outer case as in the photo. I turned an adapter out of a bit of scrap steel bar which I silver brazed in place. Finally I silver brazed a patch onto the bottom of the outer skin over the 14mm hole

    The exhaust gases go into the inner chamber then pass into the space between the inner and outer casings and then out through the random holes. It works very well and it’s cheap!

  5. SilencerSllencerHeater InstallationI have just got my shed heater up and running, I didn’t want to mess about filling it up so I mounted it on staging with a four gallon diesel reservoir underneath. I have a submerged 24 volt pump in the reservoir so topping up is a breeze. I made a silencer for it using a redundant stainless vacuum flask. This is very effective, when standing near to it the sound is like a small gas torch. A few yards away an there is no noticeable noise.

  6. You can avoid all of that long-drawn out process by pinning the surfaces down after shrinking and doping.

    if you do decide to go the twist it out route you will be doing it a lot because the warps will always come back.

  7. The method I use is to dope both sides of the wing and then pin it down using scraps of 3mm balsa sheet to keep it all clear of the board. You can use scraps of polythene bags to stop the wing from sticking to the packing pieces.

    I also do this when water shrinking the tissue, I always use Esaki lite from Balsa Cabin or FF Supplies which I put on damp using dope as the adhesive. I dope the bare framework first.

    I hope this helps, it always works for me and many other free flight people.

  8. It’s not bad I had one of these with different badge/colour and it was ok. It will not have anything like the power or rigidity of a Bridgeport so you may find that you can’t use the bigger cutters that the Bridgeport can. As for quality, they are Chinese machines built down to a price so you get what you pay for. That said, there are a lot of people who turn out good work on them.

  9. The red wine thing is a bit of folk history really. I suffered for years until th doctor put me on Allopurinol which sorts it out completely. I used to get it in my knees, my feet and my back.

    The things you should avoid are liver, kidneys, oily fish, peas, in fact any food rich in purines. Or you can do as I do, I take one pill a day and get on with my life.
