Will you make custom length turbine pipes for those os us who prefer our smoke tubes to dump outside the plane?

I did a few custom orders early on, but I prefer to stick to 3 lengths nowdays. 10",12",& 14" it's easier to keep tube blanks and mailing tubes in just a couple lengths at this time. I wasn't able to produce custom orders in a timeframe that I thought was acceptable. I build these in batches and sometimes it can be a month between welding a batch.

When I was doing it, it was an additional $2 per inch for any tubes longer than the 14" with a 24" max length.

Product development

I have made some prototypes of possible new products to add to the smoke nozzle and accessory line-up.

First up is the aluminum smoke nozzle kit. Machined from 2024 aluminum stock. Actually a few grams lighter than titanium nozzles. Standard size nozzle orifice.

Second is the remote connect brass nozzle kit. This nozzle is fed from a soft copper tube keeping the soft smoke oil supply line further from the muffler or header pipe. Nozzle has an extended depth adjustment due to more threaded length. Once the nozzle is positioned and locked into place with the captured washer locking nut, a length of K&S #8118 (3/32" x0.014" soft round copper tube) is inserted into a counterbore and soldered in place. A brass single barb pressure fitting nipple is then soldered onto the opposite end of the K&S tubing for a secure soft smoke oil supply line connection. Nozzle has standard size orifice.

Brass pressure nipples. Brass single barb with a 10-32 threaded end. These are great for carb diaphragm venting, fuel cans, etc.

Next we have the preheater kit. Consisting of 2 brass single barb pressure nipples it requires and a length of K&S #8118 (3/32"x 0.014" soft round copper tube. Preheaters can be built a couple different ways. Solder the brass pressure nipples to each end of the preheater tube and wrap tube around the cylinder base between cylinder cooling fins. Smoke oil enters the coil is heated by the heat transfer from they cylinder and then exits the coil. A short length of high temp smoke oil line makes the final connection to the smoke nozzle.
Another way to preheat is to drill and tap 10-32 holes directly across from each other on your muffler making sure that no interior baffles or obstructions in between. Thread the pressure nipples into the tapped holes and then pass a length of K&S #8118 3/32"x 0.014" soft round copper tubing through the muffler and extend past the tip of the pressure nipple by 1/16" on each end. Solder the copper tubing to the brass barb to create a single pass heat exchanger tube. Once soldered to the nipples on opposite sides of the muffler they will not be able to unscrew or come loose.

The K&S tubing I may offer in the future but due to shipping, I would rather have customers source the Copper K&S tubing.

Lastly, DIY Atomizing turbine smoke tube nozzle tips. Build your own turbine smoke tubes to your spec length. Required tubing is 304 Seamless tubing 3/16"OD x 0.028" wall available from McMaster Carr. Smoke tube nozzle tips insert into tubing and you TIG weld, braze or silver solder on to your seamless tubing to your required length. Smoke tube nozzle tips are available in standard orifice or high output orifice sizes.

Hereis how I get the most out of smoke. Needless to say one first needs to install Bad Dog smoke nozzles, there is no better way to inject the oil. After that I start by wrapping the header or can numerous times with 1/8" soft copper tubing, in this example there is 26 inches of copper tubing on each header. I like to start the tubing where the oil will be going in and at the end fold it back over to the same point, this gives more tubing for the oil. Pic #1 Also would like to note that the hottest point on the header is the outside of the bend and that is where I point the nozzle.
Then I wrap the tube with automotive exhaust wrap and secure it with stainless steel zip ties, just enough to hold the exhaust wrap securely. Usually one on each end and one in the middle is more than enough. Pic#2
Next I cover the exhaust wrap with exhaust tape. This tape is not necessary but holds the exhaust wrap long enough for it to form itself to the header. I learned the exhaust wrap formed to the exhaust when I had to make a repair. Pic#3
I use some normal zip ties on the tape to hold it securely until it has been heated, heating activates the adhesive. Pic#4
And lastly the exhaust assembled and ready for use. #5

I have measured temps under this type of wrap up to 500. This really aids in running less oil and having no residue on an airframe.

Thanks Acerc! I've always wanted to wrap a muffler or header with copper but I could never figure out how to hold the tubing in place.

Teflon tape works well also. I like the brand blue monster as it's a little thicker than the plain whit stuff. Wrapping is beneficial to hold some heat in. Heat tape as acerc described will do a better job. It also prevents rattles and vibration of the tubing against the header which could lead to wearing a hole or thin spot in the copper tubing or header over time.

If not using an over wrap and there is any concern about vibration 100% silicon can be used on, under, and around the copper tube.

Valach header no-weld kits now available 17.6mm & 19.6mm

Been in collaboration with Dr G. Vogelsang and I now offer no-weld kits sized for Valach header pipes. Website will be updated soon with the addition of 17.6mm & 19.6mm No-weld kits.

Plan on adding 5mm thread pattern nozzles soon. I have build a few for customers requests. 5mm threaded nozzles are sized for direct fitment in Moki radial ring mufflers.

The cream colored Riley model B with Moki radial running 1- 5mm threaded smoke nozzle gives a respectable amount of smoke versus the twin Valach boxer running a pair of fabricated smoke fittings.

Smoke setups for Moki radials

Now offering M5x0.8mm smoke nozzles for direct fitment into late model Moki radials with the M5 smoke port.

Early Moki radials before the implementation of smoke ports can add smoke easily utilizing the Moki radial no-weld kit nozzle adapter which allows simple addition and installation.

Here's a link to an installation write up from the BDS website.
