Prop Shaft Supports

[Angus TaylorParticipant @angustaylor79395]

I have a model which I need to fit Prop Shaft supports to. These are the standard type (brass) A frame which I need to attach to the hull (GRP). How should I do this? Do I need to epoxy the A frame to the hull with the propshaft in situ or do I need to cutout the hull, slot the A frame support in place and epoxy?

You’ll need to tack-glue both in place at the same time or you’ll have the devil’s own job trying to mate them up afterwards.

I find this is a situation where super glue is handy. My limited experience of fitting A-frames is that everything has to be in place at the same time as Dave suggests, this may entail over-large holes for the supports so as to get them in the right place. Plasticene or even blu-tac is handy to hold things together initially, then a spot of superglue when ready and hey presto. Check everything spins ok and set properly with filler/Araldite/whatever   (do not ask this forum which glue is best to use as you will get too many differing replies)!

hi ya there, if you make a small jig which fits between the two prop shafts at the correct distance and also the correct height from the base of your hull and attach the prop shafts as shown in the pic.    This will enable you to acomplish the correct spacing and angles for your prop shafts and also A frames. 

 

Tac the prop tubes into position with Super-glue and then when you are happy with that, epoxy them in place.   You can then fit your A frames.

 

One thing to remember though, when you are fitting the A frames, you will have to cut slightly larger slots in the hull to allow for slight movement and realigning the A frames.   When you are happy with the positioning, you can epoxy them in place.

 

Hope this helps
