Engine Standoffs
<span style="font-size: 9pt; font-family: Arial">Hi, Can I use 2 solid wooden blocks to mount the engine on, made out of beech or something similar, instead of using aluminium standoffs?? The weight issue isn't a problem?? Thanks 3D er</span></p> |
RE: Engine Standoffs
Yes you can.

RE: Engine Standoffs
There was a thread going on here not long back where a guy made stand-offs out of a balsa block that was hardened by CA and backed by lite ply. Goes to show that with a bit of imagination you can engineer anything to work.

RE: Engine Standoffs
I have used 3/4" dowel, squared wood stock would be a better bet as to getting more accurate cutting to size. I will stay away from balsa for this purpose.

RE: Engine Standoffs
Balsa compresses too easy. I would avoid it. You need either a nice hard wood or metal as a material.

RE: Engine Standoffs
I use hardwood dowel for short or medium length standoffs...up to 1-1/2 inches in length (personal choice), and then hardwood square stock, for longer lengths, so I can box the sides with some thin ply to form a strong, vibration resistant structure. These options are light weight, and cost effective....

RE: Engine Standoffs
Yes, and your engine will vibrate much less than if it where on "leggy" standoffs.

RE: Engine Standoffs
Thanks!!
Thought they would be better than aluminium standoffs!! as there is more surface area on the softer plywood firewall with a solid beech block. I thought that over time the aluminium standoffs would eat there way into the firewall. And they also seem to be ££££ for what they are!! 3D er |
RE: Engine Standoffs
....and besides....this is a hobby! It's great to maintain some building skill and imagination, rather than paying high dollar for a shiny off the shelf item all the time :) The icing on the cake in this case, is that its a better setup in the long run. :D

I have been using 1" red oakdowels to support a ZDZ80 engine on a 1/3 scale Super Decathlon for 5 years. I did cap the ends with steel washers. I don't know if that was necessary. I did build in a 2 degree slant into the dowels for engine offset. They are very light and have nevercaused any trouble.

Yes and I epoxied the standoffs to the firewall for convenience.

Heres a link to a thread where Iused End Grain balsa to make a standoff for a 116cc engine.

This is how I do it nowadays.<a href="http://www.zrcgf.com/pages/files/Engine%20Mounting%20Technique.pdf">
