bt20 hojo?

[dhbarr]

My kiddo sketched something with a nosecone that looks similar to an Honest John at about 18mm tube size.

I haven't had any luck turning something up. Thoughts?

Not sure what you are asking.

Try again?

If you are looking for a BT20 sized HoJo cone check Balsa Machining Services website.

I think I have looked through everything at BMS & Flis, but didn't turn one up?

I'll go back and look again, and try not to buy a bunch of other things :-D

Only other source I can think of might be Semroc then.

Yup, no dice. Flis NCB-20SC seems closest.

Surprising to me considering how often the HoJo gets cloned.

Hmm, SEM BC-760?

Its really long at 6".

Yup, those seem to be about the closest at "not very". I suppose I'll have to turn one or more for him, which moves this project _way_ down the list.

Some ideas if you decide to pick this up again:

• Using a transition like the Estes K-27 kit? https://www.spacemodeling.org/jimz/estes/k-27.pdf
• Mating a nosecone to a transition, like the Honest Goon? https://www.rocketreviews.com/unknown-honest-goon.html?
• Mating/gluing the NC to an inverted NC and a coupler?

Post the sketch & pics!

Not a huge difference between bt-20 and bt-50........
