Monitor vane Mounting Bristol 35.5

Hello all,
I am mounting an ancient Monitor Vane (serial number 023- they had hopes of making hundreds of these) to my Bristol 35.5. I have the mounting diagram from Scanmar. Since my tubes are slightly smaller, I cannot use the standard mounts, plus I am way too tight to pay their prices. I got a couple of prebent SS tubes from Jeg's Speed Shop for $24 each, shipped. I have made the tube mounts from cut down SS square tube stock. I have tube stock for the lower tubes as well, just need to get the ends smashed flat somewhere.

Couple of questions-

What size bolts are used to mount the brackets and the vane?

Any one familiar with running the steering lines for this thing on this particular model? I looked at Scanmar's gallery and it did not help much.

Thanks.

Re: Monitor vane Mounting Bristol 35.5

Well, I got it mounted on the transom. I had 5/16 holes in the original mount tubes so went with that and 1/4" on the lower tube mounts on the vane. I used 1/4" bolts to mount the brackets. I had my local welder mash the tube ends on his hydraulic press, squished one end, then I cut and marked the other end and he did those with my assistance to hold it correctly. He only charged me $20, which seems quite fair. I set it about 1-1/2" to 2" higher to allow for a lower waterline when loaded for cruising.

Still need to figure out the lines to the wheel and the air blade adjuster.

I did it solo and with the boat in the water, hanging over the transom. Suspended it from a spinnaker pole resting on the pulpit. Did not have a dink which might have been helpful. Looks pretty decent if I do say so myself.

I can see you are going to have problems with your swim ladder too. I managed to mount ours off to the side but it is a tight fit.

Re: Monitor vane Mounting Bristol 35.5

It mounts with clevis pins and will be removed. Figuring out the mount was a priority, although I have pulled the vane off for the time being, leaving only the brackets installed.
