It’s time for me to order more 76mm tubing again and make more hardware. I’ve had a few requests in previous months about making a long 76mm case so I considered doing a small run of ~57” long cases. These can be used for very high performance reloads, or as mandrels for making your own custom made composite airframes, or for both. They will be type 3 hardcoat plated the same as all of the latest Loki hardware has been.
This is quite possibly your only chance to get tubing in a 75/76mm motor case of this high of quality, at this long of a length with the straightest tubing you can have made in this size. Tubing specifications are called out by ID and wall so the OD is only a reference which is 2.985”. The ID tolerance is +/-.007” IR and the wall is +/-.006” IR. IR stands for individual reading. This means that for every inspection reading location, it has to be within those tolerances. Most tubing tolerances are twice this amount, and they are for the average tolerance of all location readings, not individual readings. After measuring the OD on the entire length of a few current 76/8000 cases on hand, I found a maximum OD variance of only +/-.0025”. That is outstanding!
I would like to get a minimum of about 10 cases or so to make them as cost effective as possible, otherwise the anodizing cost would be relatively high for only doing a few. If I get less than 10 orders, I’ll see if I can still make it work.
Pricing will be set at $355 for the hardcoat finished case only with a low profile thrust ring.
Complete hardware with the addition of snap rings, nozzle washer, bulkhead and nozzle will be priced at $485.
These prices are very reasonable in my opinion if you compare them to the gold type 2 anodized 75/10000 (55.7” Kosdon hardware pricing from 2000. At only a 10% increase for either the case with no thrust ring or for the complete hardware, that’s not bad at all for 17 years of inflation! Compare this with other current brands and it is still an excellent value.
Please note that graphite nozzles (FOR THIS HARDWARE) will not be warrantied for any reason. They are normally only good for one use in cases this long anyway. Also, I would highly recommended that nothing less than Loki Research X grade liner sets be used with this hardware. If you want a set of liners and casting tubes for your hardware, I will include plenty enough of X grade liner and casting tube material for you to cast a motor for only $50. Using standard 76mm Loki internal components you will have at most 52.125” of propellant length using a standard Loki graphite nozzle.
If you would like to purchase one of the above, please send me an email with everything you would like by Dec. 18th.
In the subject line you must put 76/13000 Purchase or it may be missed if it gets filtered into junk mail. Send it to scott (AT) Loki Research –DOT- com… without all the extra stuff. Please post this to your local EX boards/forums as well. All purchase requests need to be received no later than Monday December 18th. I’m sorry for the short notice as well but better late than never. You will be charged 50% upon order acceptance once I have enough orders and 50% plus shipping at the time of delivery. Delivery is estimated to be by the end of April.
For those wondering if I will be making reloads for these, for now the answer is no, so don't purchase one for that reason. However I would make myself a case or two so I have something to do testing with if time permits.
PS. please no PMs about this here but feel free to email this to your friend and re-post it on any local message boards.
Disclaimer- if you purchase one in order to make your own reload, buyer assumes all risks. I assume you should know what you are doing.
